== AA ==

[[AA]] is asynchronous, healthy and helpful way to document and validate activites.

[[AA]] is a social system for coordinating
distributed teamwork where each participant stays logged for at least 2 hours a day,
publicly microblogging
their development activities related to assigned tickets (self-assigned or team-assigned). At the end of each
daly session, a video log is recorded and [http://vimeo.com/channels/labmacambira uploaded to a public video channel],
the text log is also [http://hera.ethymos.com.br:1080/paainel/casca/ published on the Web] and is
peer-validated for quality. The AA system and its underlying software
engineering methodology enables self-funding for distributed collectives of
developers working on FLOSS projects.

=== AA Client ===
[[Imagem:Aa-macaco.png|right|bottom|alt=AA Console Client]]

AA user end. AA client enables messages to be sent to AA server.

'''Objective:''' AA is a distributed system following a client-server
architecture. Each AA client is a Python application in textual or GTK+ form that communicates
with the AA server, the web instance. Through the client each developer can send
messages and log his activities. Currently, AA client is a simple program
written to run in Linux. Being a software that aims to be used by everyone
it would be important to be multiplatform (perhaps as a web client) and to have
additional functionalities such as better Trac and Git log integration, RSS/Google+
developer feeds, and automatic videolog watermarking. A student working on AA could
work on these features for the program.

[[Imagem:Aapp2.png|right|bottom|alt=AA GTK2 Frontend]]

'''Suggested Roadmap:'''

1) Understand the AA architecture;

2) Use AA in its current form to understand, as a developer working in a collaborative group, what features are most needed. These features could be implemented during the summer or documented for a future developers;

3) Research about how to make AA multiplatform;

4) Implement AA Client as a Web app and make it run on GNU/Linux, MacOS and Windows;

5) Extend the functionalities of AA Client as IRC bot (there is already a Supy Bot plugin, more at http://wiki.nosdigitais.teia.org.br/IRC_DEV)

6) Increment CLI: better AA command line interface to timers, daemons, git, etc. More info: http://wiki.nosdigitais.teia.org.br/AA_%28English%29#Where.3F

7) Add tags: Enhance AA message tagging system.

8) Implement the features on the TODO of the project and some of the features listed by yourself if possible;

9) write a paper about the AA methodology and experiences with the implemented system.

=== AA Server ===

AA is a distributed system for coordinating decentralized teamwork, as described above. We need to develop the server side of AA, which already includes an aggregator of logs, and a master aggregator of all the team information in a dashboard which is similar to iGoogle: [http://hera.ethymos.com.br:1080/paainel/casca/ pAAinel]. Currently, [http://hera.ethymos.com.br:1080/paainel/casca/ pAAinel] merely displays information about logs registered by the AA server, together with complementary information, like a recent irc log, tickets and last screencasts and code commits.

Message receiver and host. More info: http://wiki.nosdigitais.teia.org.br/AA_(English)

==== pAAinel ====
[[Imagem:Aa2.png|right|bottom|alt=AA]]

A django interface with AA shouts, last videos, tickets, IRC messages, etc.

'''Objective:''' Enhance Paainel for selective and informative visualizations.

'''Suggested Roadmap:'''

1) Understand the current AA architecture;

2) Read both pAAinel (made in Django) and AA server (in PHP) code and associated documentation, planning how to rewrite AA server as a module inside pAAinel;

3) To develop and test the new pAAinel together with members of LabMacambira;

4) Continuouslly document the process.

== Online deliberation mechanisms ==

Decision making as a social right. Conceptual background in Digital Direct Democracy (see the open letter in http://li7e.org/ddd2)

=== [http://wiki.nosdigitais.teia.org.br/GT-Web#.C3.81gora_Communs_.28atual_.C3.81gora_Delibera.29 Ágora Delibera] ===
[[Imagem:Agora2.png|right|bottom|alt=Ágora Delibera]]

Envisioning direct democracy, this simple deliberation algorithm has been used in different forms by collectives and in software. From a PHP or Django ''hacksware'' to state of art direct democracy as is Delibera, from [http://www.ethymos.com.br Ethymos], a LabMacambira.sf.net partner and co-worker. In fact it is in use by ONU in almost 90 countries for 'habitation rights'. There is also an interesting LabMacambira.sf.net REST version already being tested and an official release o Delibera, from Ethymos partners, envisioning this year's election for mayors and councillors. There is a national alliance dedicated to direct democracy
going on and writing the [http://pontaopad.me/cartademocraciadireta Open Democracy Letter] which encourage and support
the use of Agora Delibera's mechanisms and codes for representative mandates and public sphere.

'''Objectives:''' Enhance REST deliberation tool to acceptable standards of use for elected representatives. Explore
Ágora Communs; ''hacksware'' to implement and test deliberation modes. With permission to viewing and posting. Test and
implement email, SMS, etc interfaces to Ethymos' Delibera.

'''Suggested Roadmap:'''

1) Study ágora delibera's [https://github.com/teiacasadecriacao/agora-communs/wiki simple mechanism for deliberation];

2) Get in touch with ongoing [http://wiki.nosdigitais.teia.org.br/GT-Web#.C3.81gora_Communs_.28atual_.C3.81gora_Delibera.29 team and code];

3) With current development team, choose core features to better apps;

4) Work close with team in irc channel #labmacambira and maybe try working with [[AA]] as methodology and documentation.

== Open Health ==

Free culture related health initiatives.

=== SOS ===
[[Imagem:Sos2.png|right|bottom|alt=SOS]]

SOS (Saúde Olha Sabedoria): a popular and ethnic heath related knowledge collection and difusion. Example implementation: http://hera.ethymos.com.br:1080/sos

'''Objective:''' Fix some bugs on SOS and extend the concept to other areas, creating a knowledge base around popular culture

'''Suggested Roadmap:'''

1) Understand SOS architecture. It was written in Python using Django, so it is important to have a minor knowledge of these technologies;

2) Look at our Trac for bugs related in SOS and fix them;

3) Look for new features. The Trac is again a good start;

4) Extend the SOS to allow the insertion of other kinds of knowledge, not just related with health;

5) Test the platform with people of Pontos de Cultura and collect their feedback.

[http://toplap.org Live coding] is an alternative way to compose and interpret music in real-time. The performer/composer plays on a laptop and shows your screen to the public, making them part of the performance and even understanding what the musician is really doing to generate that sounds. Live coders commonly use general domain languages or creates their own computer music languages. [http://automata.github.com/vivace Vivace] is a Live coding language that runs in Web browsers using the new [http://www.w3.org/TR/webaudio/ Web Audio API] for audio processing and [http://popcornjs.org Popcornjs] to video sequencing. We want to extend Vivace features like the possibility to apply more complex audio synthesis, create [http://seriouslyjs.org/ processing routines to video], integrate Vivace with [http://threejs.org threejs] to make possible the creation of 3D shapes and text in real time, and work on other [http://github.com/automata/vivace/issues available issues].

'''Objective:''' Continue to add features to Vivace, a Livecoding language that runs on Web browsers.

'''Suggested Roadmap:'''

1) Understand the architecture of Vivace, Web Audio API and Gibber, another amazing Web live coding language;

=== reacPad ===

In general, reacPad is a Pad for multimedia. Images, drawings, graphs, videos and code can be placed and edited inside the Pad in a collaborative way. It is inspired by the principles of [http://worrydream.com/Tangle/ reactive documents] by Bret Victor and [http://fed.wiki.org federated wiki] by Ward Cunningham. Technically, reacPad is a plugin to [http://etherpad.org EtherPad] which makes possible to insert those media inside EtherPads and to be programmable collaborative the same way EtherPad already does for common text.

Important to say that EtherPad is an interesting tool to civil society. With pads we are creating logs for reunions and documents of many kinds (take a look at our page [[Epads]]).

'''Objective:''': Create a plugin to [http://beta.etherpad.org EtherPad Lite] to make possible to embed JavaScript scripts, images and videos inside a pad.

'''Suggested Roadmap:'''

1) Study the EtherPad Lite architecture;

2) Be part of EtherPad Lite mailing list and IRC channel and review the status of plugins development;

3) Develop the plugin inside the plugin system to embed the scripts;

4) Test the plugin and install a demo and public version on our server.

'''Repos:''': The EtherPad Lite GIT repos is a good starting point https://github.com/Pita/etherpad-lite

=== [[AirHackTable]] ===
[[Imagem:Aht.png|right|bottom|alt=AHT]]

The [[AirHackTable]] is an art project - an interactive music instrument based on advanced computer vision algorithms that track flying origamis, associating their trajectories, color, and shape to different musical properties. The recycled coolers inside a cardboard table (itself an origami) generates a layer of air on top of which colored origamis float around and make track patterns depending on their geometry. A set of webcams on top then captures those patterns through our own color detection and 3D reconstruction algorithms, and then generate and modulate sounds based on the trajectory, color, and shape of the origamis. Many are the technological spinoffs of this project, most of which were accepted officially into well-established software such as the [[Pd]]/Gem real time multimedia programming system and [[Scilab]].

'''Objective:''' The [[AHT]] project is an opportunity to develop and spread cutting-edge technology in a playful manner, which may seem otherwise too hard/unapproachable.
We plan to improve geometric recognition to be used for generating sounds for modulating voices that are in agreement with the geometry of the origami. The goal, then, is to implement algorithms for 3D edge/curve reconstruction from the mentor's research, in order to recover the origami's edges in 3D, thus recovering the true geometry of the origami. Other techniques such as 2D recognition of origami silhouettes should also be developed. This playful project is expected to generate technological spinoffs which will be incorporated into other well-established FLOSS projects such as [[Pd]], [[Scilab]], [[OpenCV]], and [http://vxl.sf.net VXL]. Some of the Google projects that can benefit from the underlying machine vision technology include Google Streetview, Google Book scanning, Google Image Search, and Youtube.

'''Suggested Roadmap:'''

1) Compile and run the current system after downloading the large set of repositories and watching our screencasts;

2) Brush up on the background: [[Pd]], [[C++]], and Computer Vision, by talking to the mentors and watching our screencasts;

3) Get the 3D reconstruction system up and running isolatedly;

4) Optimize the system to run in real time;

5) Incorporate the 3D reconstruction system into the [[AHT]] system;

6) Write up documentation and papers on the core technologies.

7) Bonus: Write musical PD Patches to play with AHT synthesis.

8) Bonus: Cerate a Web interface for the AHT camera visualization and synthesis audition.

ABeatTracker is a music software for real time execution of specialized macros
that play rythmic patterns with samples. Its internal module ABeatDetector (ABD),
is a rythmic analiser oriented towards indicating periodicities (symmetryc overal duration cells) in a
tapped in rythm. Its porpuse is to indicate musical cells and successions
that can be used immediatelly in ABT, making it possible to really
play live indicating structures that makes sense and develops what your
partner or base is playing.

'''Objectives:''' blend ABD's rythm analyser with ABT's frontend. Enhance ABT or port it to javascript. Would be really good if ABD and ABT where finaly conected and
ABT could then use ABD's rythmic analysis. Also, ABT could have a Vi or Emacs interface
for live performance with approppriate shortcuts and abbreviations for musical code
execussion.

'''Suggested Roadmap:''' while open for student creativity, musical execution of the code
will reveal hacks that creates interesting musical structures. In a way or another,
it would be good so recover or redesign ABD's code (it has been schatched or broken) and
its communication with ABT.

Also, creating 'presets' and abreviations in Vi or Emacs
will provide lots of sound banks and 'musical set' examples. This ideally leads to further
development of livecoding interfaces in Emacs and Vi.

=== [[SIP]] + [[Scilab]] ===

[[Imagem:SIP_whitebg.png|right|bottom|alt=SIP toolbox]]
[[Imagem:Leptonica.jpg|right|bottom|alt=Leptonica Image Processing Library from Google]]

[http://siptoolbox.sf.net SIP] stands for [[Scilab]] Image Processing toolbox. [[SIP]] performs imaging tasks such
as filtering, blurring, edge detection, thresholding, histogram manipulation,
segmentation, mathematical morphology, color image processing, etc. It leverages
the extremely simple [[Scilab]] programming environment for prototyping complex computer
vision solutions.

'''Objective:''' First, to add functionality to the Google FLOSS project
[http://www.leptonica.com Leptonica] and interface most of this C library with Scilab.
Second, to throroughly document this library. Google projects that will most
benefit from this effort include Google Book search and Google Image Search.

'''Suggested Roadmap:'''

1) Run leptonica and SIP;

2) Make a contribution to Leptonica (at least a simple bugfix), which will help the student get started;

3) Write the necessary C infrastructure to interface Leptonica image structures with Scilab matrices;

4) Interface a Leptonica functionality with Scilab and document it thoroghly;

5) Repeat 4, prioritizing functions that can only be found in Leptonica.

=== [[Scilab]] Interactive Visualization ===

[[Imagem:Scilab_logo.gif|200px|right|bottom|alt=Scilab]]

[[Scilab]] is a free rapid prototyping environment for numerical algorithm
development, similar to Octave, Matlab and (to some extent) Python. A powerful
interactive GUI is one of the main features that makes Scilab stand out from
Python and Octave in their current form. This is a central feature of scilab,
specially for large-scale data mining; the capability of interactively
exploring visual data to/from the scilab language is a fundamental part of
the process of prototyping a solution to a given problem.

'''Objective:''' This project aims to improve interactive data exploration and
editing features of Scilab graphics. In other words, the aim is to make plots
more interactive with data (clicking + deleting a curve, clicking + obtaining
data from a curve, etc). Primary objectives include: to improve tooltip
functionality, to improve editing capabilities, and to improve selection of
plots and inspection of values into a scilab varialble, both in 2D and 3D. This
basically means treating the scilab graphic window as a vector graphics, through
an editing interface, and then being able to get the data back in scilab. Other
objectives include the use of OpenGL for speeding up the speed of (vector)
graphics rendering in general, but always focusing on interactive features
(dragging points from a plot curve and obtaining the corresponding data, etc)

'''Suggested Roadmap:'''

1) Compile scilab from source and understand the graphics branch from Git;

2) See what has already been done, by carrying out minor changes in the code and contributing bugfixes as a starter project;

3) Code the visual selection of individual points and curves and 3D surfaces, and outputting curve properties into a
scilab variable;

4) Improve the inspection of individual curve/surface elements/points with a tooltip;

5) Code the deletion of isolated points and curves from a plot;

6) Code point and curve editing functionality: click and drag a point will change its (x,y) data. Similar for curves and surfaces, but dragging each individual sample points independently, or even Bezier-style functionality could be added.

=== [[Scilab]] Fast and Flexible Image (Raster) Display ===
[[Imagem:SIP-shot4.png|250px|right|bottom|alt=Scilab]]

[[Scilab]] is a free rapid prototyping environment for numerical algorithm
development, similar to Octave, Matlab and (to some extent) Python. A powerful
interactive GUI for displaying raster data (matrices, images, marked pixels,
etc) would be one of the main features that makes Scilab stand out from Python and
Octave in their current form. Interactive graphics is a central feature of
scilab, specially for developing new image processing algorithms; the capability
of interactively exploring raster visual data to/from the Scilab language is a
fundamental part of the process of prototyping and debugging a new algorithmic
solution to a given image analysis problem.

'''Objective:''' This project aims to improve interactive '''raster''' data exploration and
editing features of Scilab graphics. In other words, the aim is to make image
display more interactive with data (clicking + modifying a pixel, clicking + obtaining
associated data from a pixel, etc). Primary objectives include: to improve tooltip
functionality, to improve display capabilities, and to improve selection of
pixels and inspection of their values and associated data into a scilab
varialble, both in 2D and 3D. This basically means treating the scilab graphic
window as a buffer from a raster graphics editor (such as GIMP), through an editing interface, and then being able
to get the data back in scilab. Other objectives include the use of OpenGL for
speeding up (raster) graphics rendering in general, but always
focusing on interactive features and flexible displays. Each pixel should be
efficiently displayed, not only with traditional OpenGL functionality such as pan and zooming,
but most importantly with the ability of having custom ''markers'' to overlay on
the pixels in a fast way. Many image processing algorithms require pixels to be
marked in order to be debugged or animated.

'''Suggested Roadmap:'''

1) Compile scilab from source and understand the graphics branch from Git;

2) See what has already been done, by carrying out minor changes in the code and contributing bugfixes as a starter project;

3) Code the visual selection of individual pixels, and outputting pixel properties (which can be a complex data structure) into a scilab variable;

4) Optimize the speed of the image display;

5) Improve the inspection of individual pixels with a tooltip;

6) Code the display of individual pixels with custom markers, in a fast way
using OpenGL;

7) Finalize a complete fast and flexible display for image/raster data in Scilab. Incorporate it into a full-fledged fast <tt>imshow</tt> function in SIP,
the Scilab Image Processing toolbox.

IRC bots are social technology by nature. Autonomous software agents that can talk directly with people are powerful tools to understand their needs. We visualize IRC as a direct channel to communicate with people. Macambot, Lalenia and coBots are Supybots, Python IRC robots we want to continuously develop as agents that can collect software features proposed by the people and interact with them.

'''Objective:''' Continue the deveopment of the Supybots Macambot, Lalenia and coBots.

'''Suggested Roadmap:'''

1) Understand Supybot and its plugins;

2) Develop a test plugin to interact with people collecting their suggestions as software features;

3) Study Python NLTK (Natural Language Toolkit);

4) Improve the plugin with natural language processing, to talk with people "as a human";

5) Create a Trac plugin to add bug and features entries based on the IRC bots data base of conversation with people that use #labmacambira at irc.freenode.net and/or other channels and IRC servers.

=== Permanent Conference ===
[[Imagem:Conf-perm2.png|right|bottom|alt=Per]]

Every year in Brazil we have the Conference for Defense of Children Rights along all the country. This
are ephemeral reunions, that can benefit alot from a good platform for permanent discussion.

What happens when the conference end? Where the ideas discussed at the conference goes and whats happening about it? Permanent Conference is a Web application to collect knowledge generated on these conferences and to make sure they will be available to all the people.

'''Objective:''' Continue the implementation of the Django application Permanent Conference

'''Suggested Roadmap:'''

1) Read the code already written for the application. It was written in Django, so it is good to have a minor knowledge about that;

2) Understand the [ missed features] and bugs around. Trac is a good point to start;

3) Implement the features;

4) Test with people from Pontos de Cultura from Brazil.

=Vouchers and Recommendations=

There are some honorable documents there were written to Google
itself, as recommendations and vouchers of our work. First of all,
there is this letter from Célio Turino[1], idealizer of 'pontos de cultura',
a Brazilian federal program that reaches 8,4 million people (5% of Brazilian
population). It is a formal gift from him to LabMacambira and a homage to
Cleodon Silva (1949 - 2011), who inspired LabMacambira.sf.net.
The is also a formal document from the National Commission of the almost 4000
pontos which tells a little bit more about LabMacambira.sf.net's importance
for Cultura Viva[2]. The third letter came Ethymos, a partner enterprise
(LabMacambira.sf.net is not an enterprise) that joins LabMacambira.sf.net
in a direct democracy and free medias protagonist network in Brazil.
The fourth letter came from Puraqué, a collective based in Santarém,
in the Amazonian region [4]. Worth noticing that both Amazonian Free Software
Forum (FASOL) and Amazonian Forum of Digital Culture are in the third edition,
and the text might suggest otherwise.

== AA ==

[[AA]] is asynchronous, healthy and helpful way to document and validate activites.

[[AA]] is a social system for coordinating
distributed teamwork where each participant stays logged for at least 2 hours a day,
publicly microblogging
their development activities related to assigned tickets (self-assigned or team-assigned). At the end of each
daly session, a video log is recorded and [http://vimeo.com/channels/labmacambira uploaded to a public video channel],
the text log is also [http://hera.ethymos.com.br:1080/paainel/casca/ published on the Web] and is
peer-validated for quality. The AA system and its underlying software
engineering methodology enables self-funding for distributed collectives of
developers working on FLOSS projects.

=== AA Client ===
[[Imagem:Aa-macaco.png|right|bottom|alt=AA Console Client]]

AA user end. AA client enables messages to be sent to AA server.

'''Objective:''' AA is a distributed system following a client-server
architecture. Each AA client is a Python application in textual or GTK+ form that communicates
with the AA server, the web instance. Through the client each developer can send
messages and log his activities. Currently, AA client is a simple program
written to run in Linux. Being a software that aims to be used by everyone
it would be important to be multiplatform (perhaps as a web client) and to have
additional functionalities such as better Trac and Git log integration, RSS/Google+
developer feeds, and automatic videolog watermarking. A student working on AA could
work on these features for the program.

[[Imagem:Aapp2.png|right|bottom|alt=AA GTK2 Frontend]]

'''Suggested Roadmap:'''

1) Understand the AA architecture;

2) Use AA in its current form to understand, as a developer working in a collaborative group, what features are most needed. These features could be implemented during the summer or documented for a future developers;

3) Research about how to make AA multiplatform;

4) Implement AA Client as a Web app and make it run on GNU/Linux, MacOS and Windows;

5) Extend the functionalities of AA Client as IRC bot (there is already a Supy Bot plugin, more at http://wiki.nosdigitais.teia.org.br/IRC_DEV)

6) Increment CLI: better AA command line interface to timers, daemons, git, etc. More info: http://wiki.nosdigitais.teia.org.br/AA_%28English%29#Where.3F

7) Add tags: Enhance AA message tagging system.

8) Implement the features on the TODO of the project and some of the features listed by yourself if possible;

9) write a paper about the AA methodology and experiences with the implemented system.

=== AA Server ===

AA is a distributed system for coordinating decentralized teamwork, as described above. We need to develop the server side of AA, which already includes an aggregator of logs, and a master aggregator of all the team information in a dashboard which is similar to iGoogle: [http://hera.ethymos.com.br:1080/paainel/casca/ pAAinel]. Currently, [http://hera.ethymos.com.br:1080/paainel/casca/ pAAinel] merely displays information about logs registered by the AA server, together with complementary information, like a recent irc log, tickets and last screencasts and code commits.

Message receiver and host. More info: http://wiki.nosdigitais.teia.org.br/AA_(English)

==== pAAinel ====
[[Imagem:Aa2.png|right|bottom|alt=AA]]

A django interface with AA shouts, last videos, tickets, IRC messages, etc.

'''Objective:''' Enhance Paainel for selective and informative visualizations.

'''Suggested Roadmap:'''

1) Understand the current AA architecture;

2) Read both pAAinel (made in Django) and AA server (in PHP) code and associated documentation, planning how to rewrite AA server as a module inside pAAinel;

3) To develop and test the new pAAinel together with members of LabMacambira;

== Online deliberation mechanisms ==

Decision making as a social right. Conceptual background in Digital Direct Democracy (see the open letter in http://li7e.org/ddd2)

=== [http://wiki.nosdigitais.teia.org.br/GT-Web#.C3.81gora_Communs_.28atual_.C3.81gora_Delibera.29 Ágora Delibera] ===
[[Imagem:Agora2.png|right|bottom|alt=Ágora Delibera]]

Envisioning direct democracy, this simple deliberation algorithm has been used in different forms by collectives and in software. From a PHP or Django ''hacksware'' to state of art direct democracy as is Delibera, from [http://www.ethymos.com.br Ethymos], a LabMacambira.sf.net partner and co-worker. In fact it is in use by ONU in almost 90 countries for 'habitation rights'. There is also an interesting LabMacambira.sf.net REST version already being tested and an official release o Delibera, from Ethymos partners, envisioning this year's election for mayors and councillors. There is a national alliance dedicated to direct democracy
going on and writing the [http://pontaopad.me/cartademocraciadireta Open Democracy Letter] which encourage and support
the use of Agora Delibera's mechanisms and codes for representative mandates and public sphere.

'''Objectives:''' Enhance REST deliberation tool to acceptable standards of use for elected representatives. Explore
Ágora Communs; ''hacksware'' to implement and test deliberation modes. With permission to viewing and posting. Test and
implement email, SMS, etc interfaces to Ethymos' Delibera.

'''Suggested Roadmap:'''

1) Study ágora delibera's [https://github.com/teiacasadecriacao/agora-communs/wiki simple mechanism for deliberation];

2) Get in touch with ongoing [http://wiki.nosdigitais.teia.org.br/GT-Web#.C3.81gora_Communs_.28atual_.C3.81gora_Delibera.29 team and code];

3) With current development team, choose core features to better apps;

4) Work close with team in irc channel #labmacambira and maybe try working with [[AA]] as methodology and documentation.

== Audiovisual ==

=== [[AirHackTable]] ===
[[Imagem:Aht.png|right|bottom|alt=AHT]]

The [[AirHackTable]] is an art project - an interactive music instrument based on advanced computer vision algorithms that track flying origamis, associating their trajectories, color, and shape to different musical properties. The recycled coolers inside a cardboard table (itself an origami) generates a layer of air on top of which colored origamis float around and make track patterns depending on their geometry. A set of webcams on top then captures those patterns through our own color detection and 3D reconstruction algorithms, and then generate and modulate sounds based on the trajectory, color, and shape of the origamis. Many are the technological spinoffs of this project, most of which were accepted officially into well-established software such as the [[Pd]]/Gem real time multimedia programming system and [[Scilab]].

'''Objective:''' The [[AHT]] project is an opportunity to develop and spread cutting-edge technology in a playful manner, which may seem otherwise too hard/unapproachable.
We plan to improve geometric recognition to be used for generating sounds for modulating voices that are in agreement with the geometry of the origami. The goal, then, is to implement algorithms for 3D edge/curve reconstruction from the mentor's research, in order to recover the origami's edges in 3D, thus recovering the true geometry of the origami. Other techniques such as 2D recognition of origami silhouettes should also be developed. This playful project is expected to generate technological spinoffs which will be incorporated into other well-established FLOSS projects such as [[Pd]], [[Scilab]], [[OpenCV]], and [http://vxl.sf.net VXL]. Some of the Google projects that can benefit from the underlying machine vision technology include Google Streetview, Google Book scanning, Google Image Search, and Youtube.

'''Suggested Roadmap:'''

1) Compile and run the current system after downloading the large set of repositories and watching our screencasts;

2) Brush up on the background: [[Pd]], [[C++]], and Computer Vision, by talking to the mentors and watching our screencasts;

3) Get the 3D reconstruction system up and running isolatedly;

4) Optimize the system to run in real time;

5) Incorporate the 3D reconstruction system into the [[AHT]] system;

6) Write up documentation and papers on the core technologies.

7) Bonus: Write musical PD Patches to play with AHT synthesis.

8) Bonus: Cerate a Web interface for the AHT camera visualization and synthesis audition.

that can be used immediatelly in ABT, making it possible to really
play live indicating structures that makes sense and develops what your
partner or base is playing.

'''Objectives:''' blend ABD's rythm analyser with ABT's frontend. Enhance ABT or port it to javascript. Would be really good if ABD and ABT where finaly conected and
ABT could then use ABD's rythmic analysis. Also, ABT could have a Vi or Emacs interface
for live performance with approppriate shortcuts and abbreviations for musical code
execussion.

'''Suggested Roadmap:''' while open for student creativity, musical execution of the code
will reveal hacks that creates interesting musical structures. In a way or another,
it would be good so recover or redesign ABD's code (it has been schatched or broken) and
its communication with ABT.

Also, creating 'presets' and abreviations in Vi or Emacs
will provide lots of sound banks and 'musical set' examples. This ideally leads to further
development of livecoding interfaces in Emacs and Vi.

=== [[SIP]] + [[Scilab]] ===

[[Imagem:SIP_whitebg.png|right|bottom|alt=SIP toolbox]]
[[Imagem:Leptonica.jpg|right|bottom|alt=Leptonica Image Processing Library from Google]]

[http://siptoolbox.sf.net SIP] stands for [[Scilab]] Image Processing toolbox. [[SIP]] performs imaging tasks such
as filtering, blurring, edge detection, thresholding, histogram manipulation,
segmentation, mathematical morphology, color image processing, etc. It leverages
the extremely simple [[Scilab]] programming environment for prototyping complex computer
vision solutions.

'''Objective:''' First, to add functionality to the Google FLOSS project
[http://www.leptonica.com Leptonica] and interface most of this C library with Scilab.
Second, to throroughly document this library. Google projects that will most
benefit from this effort include Google Book search and Google Image Search.

'''Suggested Roadmap:'''

1) Run leptonica and SIP;

2) Make a contribution to Leptonica (at least a simple bugfix), which will help the student get started;

3) Write the necessary C infrastructure to interface Leptonica image structures with Scilab matrices;

4) Interface a Leptonica functionality with Scilab and document it thoroghly;

5) Repeat 4, prioritizing functions that can only be found in Leptonica.

=== [[Scilab]] Interactive Visualization ===

[[Imagem:Scilab_logo.gif|200px|right|bottom|alt=Scilab]]

[[Scilab]] is a free rapid prototyping environment for numerical algorithm
development, similar to Octave, Matlab and (to some extent) Python. A powerful
interactive GUI is one of the main features that makes Scilab stand out from
Python and Octave in their current form. This is a central feature of scilab,
specially for large-scale data mining; the capability of interactively
exploring visual data to/from the scilab language is a fundamental part of
the process of prototyping a solution to a given problem.

'''Objective:''' This project aims to improve interactive data exploration and
editing features of Scilab graphics. In other words, the aim is to make plots
more interactive with data (clicking + deleting a curve, clicking + obtaining
data from a curve, etc). Primary objectives include: to improve tooltip
functionality, to improve editing capabilities, and to improve selection of
plots and inspection of values into a scilab varialble, both in 2D and 3D. This
basically means treating the scilab graphic window as a vector graphics, through
an editing interface, and then being able to get the data back in scilab. Other
objectives include the use of OpenGL for speeding up the speed of (vector)
graphics rendering in general, but always focusing on interactive features
(dragging points from a plot curve and obtaining the corresponding data, etc)

'''Suggested Roadmap:'''

1) Compile scilab from source and understand the graphics branch from Git;

2) See what has already been done, by carrying out minor changes in the code and contributing bugfixes as a starter project;

3) Code the visual selection of individual points and curves and 3D surfaces, and outputting curve properties into a
scilab variable;

4) Improve the inspection of individual curve/surface elements/points with a tooltip;

5) Code the deletion of isolated points and curves from a plot;

6) Code point and curve editing functionality: click and drag a point will change its (x,y) data. Similar for curves and surfaces, but dragging each individual sample points independently, or even Bezier-style functionality could be added.

=== [[Scilab]] Fast and Flexible Image (Raster) Display ===
[[Imagem:SIP-shot4.png|250px|right|bottom|alt=Scilab]]

[[Scilab]] is a free rapid prototyping environment for numerical algorithm
development, similar to Octave, Matlab and (to some extent) Python. A powerful
interactive GUI for displaying raster data (matrices, images, marked pixels,
etc) would be one of the main features that makes Scilab stand out from Python and
Octave in their current form. Interactive graphics is a central feature of
scilab, specially for developing new image processing algorithms; the capability
of interactively exploring raster visual data to/from the Scilab language is a
fundamental part of the process of prototyping and debugging a new algorithmic
solution to a given image analysis problem.

'''Objective:''' This project aims to improve interactive '''raster''' data exploration and
editing features of Scilab graphics. In other words, the aim is to make image
display more interactive with data (clicking + modifying a pixel, clicking + obtaining
associated data from a pixel, etc). Primary objectives include: to improve tooltip
functionality, to improve display capabilities, and to improve selection of
pixels and inspection of their values and associated data into a scilab
varialble, both in 2D and 3D. This basically means treating the scilab graphic
window as a buffer from a raster graphics editor (such as GIMP), through an editing interface, and then being able
to get the data back in scilab. Other objectives include the use of OpenGL for
speeding up (raster) graphics rendering in general, but always
focusing on interactive features and flexible displays. Each pixel should be
efficiently displayed, not only with traditional OpenGL functionality such as pan and zooming,
but most importantly with the ability of having custom ''markers'' to overlay on
the pixels in a fast way. Many image processing algorithms require pixels to be
marked in order to be debugged or animated.

'''Suggested Roadmap:'''

1) Compile scilab from source and understand the graphics branch from Git;

2) See what has already been done, by carrying out minor changes in the code and contributing bugfixes as a starter project;

3) Code the visual selection of individual pixels, and outputting pixel properties (which can be a complex data structure) into a scilab variable;

4) Optimize the speed of the image display;

5) Improve the inspection of individual pixels with a tooltip;

6) Code the display of individual pixels with custom markers, in a fast way
using OpenGL;

7) Finalize a complete fast and flexible display for image/raster data in Scilab. Incorporate it into a full-fledged fast <tt>imshow</tt> function in SIP,
the Scilab Image Processing toolbox.

IRC bots are social technology by nature. Autonomous software agents that can talk directly with people are powerful tools to understand their needs. We visualize IRC as a direct channel to communicate with people. Macambot, Lalenia and coBots are Supybots, Python IRC robots we want to continuously develop as agents that can collect software features proposed by the people and interact with them.

'''Objective:''' Continue the deveopment of the Supybots Macambot, Lalenia and coBots.

'''Suggested Roadmap:'''

1) Understand Supybot and its plugins;

2) Develop a test plugin to interact with people collecting their suggestions as software features;

3) Study Python NLTK (Natural Language Toolkit);

4) Improve the plugin with natural language processing, to talk with people "as a human";

5) Create a Trac plugin to add bug and features entries based on the IRC bots data base of conversation with people that use #labmacambira at irc.freenode.net and/or other channels and IRC servers.

itself, as recommendations and vouchers of our work. First of all,
there is this letter from Célio Turino[1], idealizer of 'pontos de cultura',
a Brazilian federal program that reaches 8,4 million people (5% of Brazilian
population). It is a formal gift from him to LabMacambira and a homage to
Cleodon Silva (1949 - 2011), who inspired LabMacambira.sf.net.
The is also a formal document from the National Commission of the almost 4000
pontos which tells a little bit more about LabMacambira.sf.net's importance
for Cultura Viva[2]. The third letter came Ethymos, a partner enterprise
(LabMacambira.sf.net is not an enterprise) that joins LabMacambira.sf.net
in a direct democracy and free medias protagonist network in Brazil.
The fourth letter came from Puraqué, a collective based in Santarém,
in the Amazonian region [4]. Worth noticing that both Amazonian Free Software
Forum (FASOL) and Amazonian Forum of Digital Culture are in the third edition,
and the text might suggest otherwise.

== AA (client) ==
[[Imagem:Aa-macaco.png|right|bottom|alt=AA Console Client]]

[[AA]] is a social system for coordinating
distributed teamwork where each participant stays logged for at least 2 hours a day,
publicly microblogging
their development activities related to assigned tickets (self-assigned or team-assigned). At the end of each
daly session, a video log is recorded and [http://vimeo.com/channels/labmacambira uploaded to a public video channel],
the text log is also [http://hera.ethymos.com.br:1080/paainel/casca/ published on the Web] and is
peer-validated for quality. The AA system and its underlying software
engineering methodology enables self-funding for distributed collectives of
developers working on FLOSS projects.

'''Objective:''' AA is a distributed system following a client-server
architecture. Each AA client is a Python application in textual or GTK+ form that communicates
with the AA server, the web instance. Through the client each developer can send
messages and log his activities. Currently, AA client is a simple program
written to run in Linux. Being a software that aims to be used by everyone
it would be important to be multiplatform (perhaps as a web client) and to have
additional functionalities such as better Trac and Git log integration, RSS/Google+
developer feeds, and automatic videolog watermarking. A student working on AA could
work on these features for the program.

[[Imagem:Aapp2.png|right|bottom|alt=AA GTK2 Frontend]]

'''Suggested Roadmap:''' 1) Understand the AA architecture; 2) Use AA in its
current form to understand, as a developer working in a collaborative group,
what features are most needed. These features could be implemented during the
summer or documented for a future developers; 3) Research about how to make AA
multiplatform - we are planning to make a Web client; 4) Implement the features
on the TODO of the project and some of the features listed by yourself if
possible. 5) write a paper about the AA methodology and experiences with the
implemented system.

== pAAinel (AA server) ==
[[Imagem:Aa2.png|right|bottom|alt=AA]]

AA is a distributed system for coordinating decentralized teamwork, as described above. We need to develop the server side of AA, which already includes an aggregator of logs, and a master aggregator of all the team information in a dashboard which is similar to iGoogle: [http://hera.ethymos.com.br:1080/paainel/casca/ pAAinel]. Currently, [http://hera.ethymos.com.br:1080/paainel/casca/ pAAinel] merely displays information about logs registered by the AA server, together with complementary information, like a recent irc log, tickets and last screencasts and code commits.

'''Objective:''' We desire to rewrite the AA microblog server (actually written in PHP) as a module inside pAAinel, a Django application.

'''Suggested Roadmap:''' 1) Understand the current AA architecture; 2) Read both pAAinel (made in Django) and AA server (in PHP) code and associated documentation, planning how to rewrite AA server as a module inside pAAinel; 3) To develop and test the new pAAinel together with members of LabMacambira; 4) Continuouslly document the process.

== [[AirHackTable]] ==
[[Imagem:Aht.png|right|bottom|alt=AHT]]

The [[AirHackTable]] is an art project - an interactive music instrument based on advanced computer vision algorithms that track flying origamis, associating their trajectories, color, and shape to different musical properties. The recycled coolers inside a cardboard table (itself an origami) generates a layer of air on top of which colored origamis float around and make track patterns depending on their geometry. A set of webcams on top then captures those patterns through our own color detection and 3D reconstruction algorithms, and then generate and modulate sounds based on the trajectory, color, and shape of the origamis. Many are the technological spinoffs of this project, most of which were accepted officially into well-established software such as the [[Pd]]/Gem real time multimedia programming system and [[Scilab]].

'''Objective:''' The [[AHT]] project is an opportunity to develop and spread cutting-edge technology in a playful manner, which may seem otherwise too hard/unapproachable.
We plan to improve geometric recognition to be used for generating sounds for modulating voices that are in agreement with the geometry of the origami. The goal, then, is to implement algorithms for 3D edge/curve reconstuction from the mentor's research, in order to recover the origami's edges in 3D, thus recovering the true geometry of the origami. Other techniques such as 2D recognition of origami silhouettes should also be developed. This playful project is expected to generate technological spinoffs which will be incorporated into other well-established FLOSS projects such as [[Pd]], [[Scilab]], [[OpenCV]], and [http://vxl.sf.net VXL]. Some of the Google projects that can benefit from the underlying machine vision technology include Google Streetview, Google Book scanning, Google Image Search, and Youtube.

'''Suggested Roadmap:''' 1) compile and run the current system after downloading the large set of repositories and watching our screencasts; 2) brush up on the background: [[Pd]], [[C++]],
and Computer Vision, by talking to the mentors and watching our screencasts; 3) get the 3D reconstruction system up and running isolatedly 4) optimize the system to run in real time
5) incorporate the 3D reconstruction system into the [[AHT]] system; 6) write up documentation and papers on the core technologies.

== [[SIP]] + [[Scilab]] ==

[[Imagem:SIP_whitebg.png|right|bottom|alt=SIP toolbox]]
[[Imagem:Leptonica.jpg|right|bottom|alt=Leptonica Image Processing Library from Google]]

[http://siptoolbox.sf.net SIP] stands for [[Scilab]] Image Processing toolbox. [[SIP]] performs imaging tasks such
as filtering, blurring, edge detection, thresholding, histogram manipulation,
segmentation, mathematical morphology, color image processing, etc. It leverages
the extremely simple [[Scilab]] programming environment for prototyping complex computer
vision solutions.

'''Objective:''' First, to add functionality to the Google FLOSS project
[http://www.leptonica.com Leptonica] and interface most of this C library with Scilab.
Second, to throroughly document this library. Google projects that will most
benefit from this effort include Google Book search and Google Image Search.

'''Suggested Roadmap:''' 1) Run leptonica and SIP; 2) make a contribution to
Leptonica (at least a simple bugfix), which will help the student get started;
3) write the necessary C infrastructure to interface Leptonica
image structures with Scilab matrices
4) interface a Leptonica functionality with Scilab and document it thoroghly
5) repeat 4, prioritizing functions that can only be found in Leptonica.

== [[Scilab]] Interactive Visualization ==

[[Imagem:Scilab_logo.gif|200px|right|bottom|alt=Scilab]]

[[Scilab]] is a free rapid prototyping environment for numerical algorithm
development, similar to Octave, Matlab and (to some extent) Python. A powerful
interactive GUI is one of the main features that makes Scilab stand out from
Python and Octave in their current form. This is a central feature of scilab,
specially for large-scale data mining; the capability of interactively
exploring visual data to/from the scilab language is a fundamental part of
the process of prototyping a solution to a given problem.

'''Objective:''' This project aims to improve interactive data exploration and
editing features of Scilab graphics. In other words, the aim is to make plots
more interactive with data (clicking + deleting a curve, clicking + obtaining
data from a curve, etc). Primary objectives include: to improve tooltip
functionality, to improve editing capabilities, and to improve selection of
plots and inspection of values into a scilab varialble, both in 2D and 3D. This
basically means treating the scilab graphic window as a vector graphics, through
an editing interface, and then being able to get the data back in scilab. Other
objectives include the use of OpenGL for speeding up the speed of (vector)
graphics rendering in general, but always focusing on interactive features
(dragging points from a plot curve and obtaining the corresponding data, etc)

'''Suggested Roadmap:''' 1) Compile scilab from source and understand the
graphics branch from Git; 2) See what has already been done, by carrying out
minor changes in the code and contributing bugfixes as a starter project
3) Code the visual selection of individual points and curves and 3D surfaces, and outputting curve properties into a
scilab variable.
4) Improve the inspection of individual curve/surface elements/points with a tooltip
5) Code the deletion of isolated points and curves from a plot
6) Code point and curve editing functionality: click and drag a point will
change its (x,y) data. Similar for curves and surfaces, but dragging each
individual sample points independently, or even Bezier-style functionality could be
added.

== [[Scilab]] Fast and Flexible Image (Raster) Display ==
[[Imagem:SIP-shot4.png|250px|right|bottom|alt=Scilab]]

[[Scilab]] is a free rapid prototyping environment for numerical algorithm
development, similar to Octave, Matlab and (to some extent) Python. A powerful
interactive GUI for displaying raster data (matrices, images, marked pixels,
etc) would be one of the main features that makes Scilab stand out from Python and
Octave in their current form. Interactive graphics is a central feature of
scilab, specially for developing new image processing algorithms; the capability
of interactively exploring raster visual data to/from the Scilab language is a
fundamental part of the process of prototyping and debugging a new algorithmic
solution to a given image analysis problem.

'''Objective:''' This project aims to improve interactive '''raster''' data exploration and
editing features of Scilab graphics. In other words, the aim is to make image
display more interactive with data (clicking + modifying a pixel, clicking + obtaining
associated data from a pixel, etc). Primary objectives include: to improve tooltip
functionality, to improve display capabilities, and to improve selection of
pixels and inspection of their values and associated data into a scilab
varialble, both in 2D and 3D. This basically means treating the scilab graphic
window as a buffer from a raster graphics editor (such as GIMP), through an editing interface, and then being able
to get the data back in scilab. Other objectives include the use of OpenGL for
speeding up (raster) graphics rendering in general, but always
focusing on interactive features and flexible displays. Each pixel should be
efficiently displayed, not only with traditional OpenGL functionality such as pan and zooming,
but most importantly with the ability of having custom ''markers'' to overlay on
the pixels in a fast way. Many image processing algorithms require pixels to be
marked in order to be debugged or animated.

'''Suggested Roadmap:''' 1) Compile scilab from source and understand the
graphics branch from Git; 2) See what has already been done, by carrying out
minor changes in the code and contributing bugfixes as a starter project
3) Code the visual selection of individual pixels, and outputting pixel
properties (which can be a complex data structure) into a scilab variable.
4) Optimize the speed of the image display
4) Improve the inspection of individual pixels with a tooltip
5) Code the display of individual pixels with custom markers, in a fast way
using OpenGL.
6) Finalize a complete fast and flexible display for image/raster data in
Scilab. Incorporate it into a full-fledged fast <tt>imshow</tt> function in SIP,
the Scilab Image Processing toolbox.

[[Imagem:Agora2.png|right|bottom|alt=Ágora Delibera]]

Envisioning direct democracy, this simple deliberation algorithm has been used in different forms by collectives and in software. From a PHP or Django ''hacksware'' to state of art direct democracy as is Delibera, from [http://www.ethymos.com.br Ethymos], a LabMacambira.sf.net partner and co-worker. In fact it is in use by ONU in almost 90 countries for 'habitation rights'. There is also an interesting LabMacambira.sf.net REST version already being tested and an official release o Delibera, from Ethymos partnerts, envisioning this year's election for mayors and councillors. There is a nacional alliance dedicated to direct democracy
going on and writing the [http://pontaopad.me/cartademocraciadireta Open Democracy Letter] which encourage and support
the use of Agora Delibera's mechanisms and codes for representative mandates and public sphere.

'''Objectives:''' Enhance REST deliberation tool to acceptable standards of use for elected representatives. Explore
Ágora Communs; ''hacksware'' to implement and test deliberation modes. With permission to viewing and posting. Test and
implement email, SMS, etc interfaces to Ethymos' Delibera.

'''Suggested Roadmap:''' Study ágora delibera's [https://github.com/teiacasadecriacao/agora-communs/wiki simple mechanism for deliberation].
Get in touch with ongoing [http://wiki.nosdigitais.teia.org.br/GT-Web#.C3.81gora_Communs_.28atual_.C3.81gora_Delibera.29 team and code].
With current development team, choose core features to better apps. Work close with team in irc channel #labmacambira and
maybe try working with [[AA]] as methodology and documentation.

== reacPad ==

We are planning to create a plugin to [http://etherpad.org EtherPad] that makes possible to run JavaScript (and maybe other languages) inside of EtherPads and to be programmable collaborative the same way EtherPad already does for common text.

Important to say that EtherPad is an interesting tool to civil society. With pads we are creating logs for reunions and documents of many kinds (take a look at our page [[Epads]]). It is interesting to take a look at [http://worrydream.com/Tangle/ Bret Victor works on "reactive documents"]. It is a kind of documents we are interested to implement using pads.

'''Objective:''': Create a plugin to [http://beta.etherpad.org EtherPad Lite] (the [[http://nodejs.org node.js]] port of EtherPad) to make possible to embed JavaScript scripts inside a pad.

'''Suggested Roadmap:''' 1) Study the EtherPad Lite architecture; 2) Be part of EtherPad Lite maillist and IRC channel and review the status of plugins development. As we know, today there is not a plugin system for EtherPad Lite, so there will be a task to create a first prototype of a plugin to the system; 3) Develop the plugin inside the plugin system to embed the scripts; 4)

ABeatTracker is a music software for real time execution of specialized macros
that play rythmic patterns with samples. Its internal module ABeatDetector (ABD),
is a rythmic analiser oriented towards indicating periodicities (symmetryc overal duration cells) in a
tapped in rythm. Its porpuse is to indicate musical cells and successions
that can be used immediatelly in ABT, making it possible to really
play live indicating structures that makes sense and develops what your
partner or base is playing.

'''Objectives:''' open for student proposal. Would be really good if ABD and ABT where finaly conected and
ABT could then use ABD's rythmic analysis. Also, ABT could have a Vi or Emacs interface
for live performance with approppriate shortcuts and abbreviations for musical code
execussion.

'''Roadmap:''' while open for student creativity, musical execution of the code
will reveal hacks that creates interesting musical structures. In a way or another,
it would be good so recover or redesign ABD's code (it has been schatched or broken) and
its communication with ABT.

Also, creating 'presets' and abreviations in Vi or Emacs
will provide lots of sound banks and 'musical set' examples. This ideally leads to further
development of livecoding interfaces in Emacs and Vi.

[http://toplap.org Livecoding] is an alternative way to compose and interpret music in real-time. The performer/composer plays on a laptop and shows your screen to the public, making them part of the performance and even understanding what the musician is really doing to generate that weird sounds. Livecoders commonly use general domain languages or creates their own computer music languages. Vivace is an attempt to create a Livecoding language that runs in the Open Web using the new [https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html Web Audio] and [https://wiki.mozilla.org/Audio_Data_API Audio Data] APIs.

'''Objective:''' Continue to add features to Vivace, a Livecoding language that runs on Web browsers.

'''Suggested Roadmap:''' 1) Understand the architecture of Vivace and [http://github.com/oampo/Audiolet Audiolet] (the awesome JavaScript Audio lib created by Joe Turner); 2) Understand features specified at TODO and present at other languages like [http://www.ixi-audio.net/content/software.html ixi lang] and ABT/ABD; 3) Implement the features; 4) Screencast performances using Vivace, maybe public ones.

IRC bots are social technology by nature. Autonomous software agents that can talk directly with people are powerful tools to understand their needs. We visualize IRC as a direct channel to communicate with people. Macambot, Lalenia and coBots are Supybots, Python IRC robots we want to continuously develop as agents that can collect software features proposed by the people and interact with them.

'''Objective:''' Continue the deveopment of the Supybots Macambot, Lalenia and coBots.

'''Suggested Roadmap:''' 1) Understand Supybot and its plugins; 2) Develop a test plugin to interact with people collecting their suggestions as software features; 3) Study Python NLTK (Natural Language Toolkit); 4) Improve the plugin with natural language processing, to talk with people "as a human"; 5) Create a Trac plugin to add bug and features entries based on the IRC bots data base of conversation with people that use #labmacambira at irc.freenode.net and/or other channels and IRC servers

Every year in Brazil we have the Conference for Defense of Children Rights along all the country. This
are ephemeral reunions, that can benefit alot from a good platform for permanent discussion.

What happens when the conference end? Where the ideas discussed at the conference goes and whats happening about it? Permanent Conference is a Web application to collect knowledge generated on these conferences and to make sure they will be available to all the people.

'''Objective:''' Continue the implementation of the Django application Permanent Conference

'''Suggested Roadmap:''' 1) Read the code already written for the application. It was written in Django, so it is good to have a minor knowledge about that; 2) Understand the [ missed features] and bugs around. Trac is a good point to start; 3) Implement the features; 4) Test with people from Pontos de Cultura from Brazil.

== SOS ==
[[Imagem:Sos2.png|right|bottom|alt=SOS]]

"Saúde Olha Sabedoria" (or Health, Look! Knowledge) is a Web application to collect popular tips around human health. People can also learn how to use popular knowledge to cure their deceases. We believe that softwares like SOS are an interesting way to preserve the culture of a nation and spread it to the others.

'''Objective:''' Fix some bugs on SOS and extend the concept to other areas, creating a knowledge base around popular culture

'''Suggested Roadmap:''' 1) Understand SOS architecture. It was written in Python using Django, so it is important to have a minor knowledge of these technologies; 2) Look at our Trac for bugs related in SOS and fix them; 3) Look for new features. The Trac is again a good start; 4) Extend the SOS to allow the insertion of other kinds of knowledge, not just related with health; 4) Test the platform with people of Pontos de Cultura and collect their feedback

A total of 11 participants in GSoC 2012 were directly related to [http://labmacambira.sf.net LabMacambira]. This was achieved by mentoring together with (other) GSoC 2012 orgs such as [http://www.google-melange.com/gsoc/org/google/gsoc2012/e_cidadania e-cidadania] and [[Scilab]]. Members of [http://labmacambira.sf.net] also took part as students, for Mozilla and the mentioned orgs. This participation focused in projects related to [[AA]], digital deliberation methods, [[Scilab]] and [[Mozilla]][http://maverickranter.blogspot.com.br/2012/05/5-bolsas-do-google-summer-of-code-dadas.html].

LabMacambira.sf.net was not selected as a GSoC 2012 organization. However, we are very proud and thankful for all the vouchers and recommendation letters written for us (and forwarded to Google) during the summer of 2012. These letters are listed in the following section.

=Vouchers and Recommendations=

There are some honorable documents written to Google
itself, as recommendations and vouchers of our work. First of all,
there is this letter from Célio Turino[1], idealizer of 'pontos de cultura',
a Brazilian federal program that reaches 8,4 million people (5% of Brazilian
population). It is a formal gift from him to LabMacambira and a homage to
Cleodon Silva (1949 - 2011), who inspired LabMacambira.sf.net.
There is also a formal document from the National Commission that gathers almost 4000
'pontos de cultura' telling a little bit more about LabMacambira.sf.net's importance
for Cultura Viva[2]. The third letter came from Ethymos, a partner enterprise
(LabMacambira.sf.net is not an enterprise) that joins LabMacambira.sf.net
in a direct democracy and free medias protagonist network in Brazil.
The fourth letter came from Puraqué, a collective based in Santarém,
in the Amazonian region [4]. Worth noticing that both Amazonian Free Software
Forum (FASOL) and Amazonian Forum of Digital Culture are in the third edition,

== AA (client) ==
[[Imagem:Aa-macaco.png|right|bottom|alt=AA Console Client]]

[[AA]] is a social system for coordinating
distributed teamwork where each participant stays logged for at least 2 hours a day,
publicly microblogging
their development activities related to assigned tickets (self-assigned or team-assigned). At the end of each
daly session, a video log is recorded and [http://vimeo.com/channels/labmacambira uploaded to a public video channel],
the text log is also [http://hera.ethymos.com.br:1080/paainel/casca/ published on the Web] and is
peer-validated for quality. The AA system and its underlying software
engineering methodology enables self-funding for distributed collectives of
developers working on FLOSS projects.

'''Objective:''' AA is a distributed system following a client-server
architecture. Each AA client is a Python application in textual or GTK+ form that communicates
with the AA server, the web instance. Through the client each developer can send
messages and log his activities. Currently, AA client is a simple program
written to run in Linux. Being a software that aims to be used by everyone
it would be important to be multiplatform (perhaps as a web client) and to have
additional functionalities such as better Trac and Git log integration, RSS/Google+
developer feeds, and automatic videolog watermarking. A student working on AA could
work on these features for the program.

[[Imagem:Aapp2.png|right|bottom|alt=AA GTK2 Frontend]]

'''Suggested Roadmap:''' 1) Understand the AA architecture; 2) Use AA in its
current form to understand, as a developer working in a collaborative group,
what features are most needed. These features could be implemented during the
summer or documented for a future developers; 3) Research about how to make AA
multiplatform - we are planning to make a Web client; 4) Implement the features
on the TODO of the project and some of the features listed by yourself if
possible. 5) write a paper about the AA methodology and experiences with the
implemented system.

== pAAinel (AA server) ==
[[Imagem:Aa2.png|right|bottom|alt=AA]]

AA is a distributed system for coordinating decentralized teamwork, as described above. We need to develop the server side of AA, which already includes an aggregator of logs, and a master aggregator of all the team information in a dashboard which is similar to iGoogle: [http://hera.ethymos.com.br:1080/paainel/casca/ pAAinel]. Currently, [http://hera.ethymos.com.br:1080/paainel/casca/ pAAinel] merely displays information about logs registered by the AA server, together with complementary information, like a recent irc log, tickets and last screencasts and code commits.

'''Objective:''' We desire to rewrite the AA microblog server (actually written in PHP) as a module inside pAAinel, a Django application.

'''Suggested Roadmap:''' 1) Understand the current AA architecture; 2) Read both pAAinel (made in Django) and AA server (in PHP) code and associated documentation, planning how to rewrite AA server as a module inside pAAinel; 3) To develop and test the new pAAinel together with members of LabMacambira; 4) Continuouslly document the process.

== [[AirHackTable]] ==
[[Imagem:Aht.png|right|bottom|alt=AHT]]

The [[AirHackTable]] is an art project - an interactive music instrument based on advanced computer vision algorithms that track flying origamis, associating their trajectories, color, and shape to different musical properties. The recycled coolers inside a cardboard table (itself an origami) generates a layer of air on top of which colored origamis float around and make track patterns depending on their geometry. A set of webcams on top then captures those patterns through our own color detection and 3D reconstruction algorithms, and then generate and modulate sounds based on the trajectory, color, and shape of the origamis. Many are the technological spinoffs of this project, most of which were accepted officially into well-established software such as the [[Pd]]/Gem real time multimedia programming system and [[Scilab]].

'''Objective:''' The [[AHT]] project is an opportunity to develop and spread cutting-edge technology in a playful manner, which may seem otherwise too hard/unapproachable.
We plan to improve geometric recognition to be used for generating sounds for modulating voices that are in agreement with the geometry of the origami. The goal, then, is to implement algorithms for 3D edge/curve reconstuction from the mentor's research, in order to recover the origami's edges in 3D, thus recovering the true geometry of the origami. Other techniques such as 2D recognition of origami silhouettes should also be developed. This playful project is expected to generate technological spinoffs which will be incorporated into other well-established FLOSS projects such as [[Pd]], [[Scilab]], [[OpenCV]], and [http://vxl.sf.net VXL]. Some of the Google projects that can benefit from the underlying machine vision technology include Google Streetview, Google Book scanning, Google Image Search, and Youtube.

'''Suggested Roadmap:''' 1) compile and run the current system after downloading the large set of repositories and watching our screencasts; 2) brush up on the background: [[Pd]], [[C++]],
and Computer Vision, by talking to the mentors and watching our screencasts; 3) get the 3D reconstruction system up and running isolatedly 4) optimize the system to run in real time
5) incorporate the 3D reconstruction system into the [[AHT]] system; 6) write up documentation and papers on the core technologies.

== [[SIP]] + [[Scilab]] ==

[[Imagem:SIP_whitebg.png|right|bottom|alt=SIP toolbox]]
[[Imagem:Leptonica.jpg|right|bottom|alt=Leptonica Image Processing Library from Google]]

[http://siptoolbox.sf.net SIP] stands for [[Scilab]] Image Processing toolbox. [[SIP]] performs imaging tasks such
as filtering, blurring, edge detection, thresholding, histogram manipulation,
segmentation, mathematical morphology, color image processing, etc. It leverages
the extremely simple [[Scilab]] programming environment for prototyping complex computer
vision solutions.

'''Objective:''' First, to add functionality to the Google FLOSS project
[http://www.leptonica.com Leptonica] and interface most of this C library with Scilab.
Second, to throroughly document this library. Google projects that will most
benefit from this effort include Google Book search and Google Image Search.

'''Suggested Roadmap:''' 1) Run leptonica and SIP; 2) make a contribution to
Leptonica (at least a simple bugfix), which will help the student get started;
3) write the necessary C infrastructure to interface Leptonica
image structures with Scilab matrices
4) interface a Leptonica functionality with Scilab and document it thoroghly
5) repeat 4, prioritizing functions that can only be found in Leptonica.

== [[Scilab]] Interactive Visualization ==

[[Imagem:Scilab_logo.gif|200px|right|bottom|alt=Scilab]]

[[Scilab]] is a free rapid prototyping environment for numerical algorithm
development, similar to Octave, Matlab and (to some extent) Python. A powerful
interactive GUI is one of the main features that makes Scilab stand out from
Python and Octave in their current form. This is a central feature of scilab,
specially for large-scale data mining; the capability of interactively
exploring visual data to/from the scilab language is a fundamental part of
the process of prototyping a solution to a given problem.

'''Objective:''' This project aims to improve interactive data exploration and
editing features of Scilab graphics. In other words, the aim is to make plots
more interactive with data (clicking + deleting a curve, clicking + obtaining
data from a curve, etc). Primary objectives include: to improve tooltip
functionality, to improve editing capabilities, and to improve selection of
plots and inspection of values into a scilab varialble, both in 2D and 3D. This
basically means treating the scilab graphic window as a vector graphics, through
an editing interface, and then being able to get the data back in scilab. Other
objectives include the use of OpenGL for speeding up the speed of (vector)
graphics rendering in general, but always focusing on interactive features
(dragging points from a plot curve and obtaining the corresponding data, etc)

'''Suggested Roadmap:''' 1) Compile scilab from source and understand the
graphics branch from Git; 2) See what has already been done, by carrying out
minor changes in the code and contributing bugfixes as a starter project
3) Code the visual selection of individual points and curves and 3D surfaces, and outputting curve properties into a
scilab variable.
4) Improve the inspection of individual curve/surface elements/points with a tooltip
5) Code the deletion of isolated points and curves from a plot
6) Code point and curve editing functionality: click and drag a point will
change its (x,y) data. Similar for curves and surfaces, but dragging each
individual sample points independently, or even Bezier-style functionality could be
added.

== [[Scilab]] Fast and Flexible Image (Raster) Display ==
[[Imagem:SIP-shot4.png|250px|right|bottom|alt=Scilab]]

[[Scilab]] is a free rapid prototyping environment for numerical algorithm
development, similar to Octave, Matlab and (to some extent) Python. A powerful
interactive GUI for displaying raster data (matrices, images, marked pixels,
etc) would be one of the main features that makes Scilab stand out from Python and
Octave in their current form. Interactive graphics is a central feature of
scilab, specially for developing new image processing algorithms; the capability
of interactively exploring raster visual data to/from the Scilab language is a
fundamental part of the process of prototyping and debugging a new algorithmic
solution to a given image analysis problem.

'''Objective:''' This project aims to improve interactive '''raster''' data exploration and
editing features of Scilab graphics. In other words, the aim is to make image
display more interactive with data (clicking + modifying a pixel, clicking + obtaining
associated data from a pixel, etc). Primary objectives include: to improve tooltip
functionality, to improve display capabilities, and to improve selection of
pixels and inspection of their values and associated data into a scilab
varialble, both in 2D and 3D. This basically means treating the scilab graphic
window as a buffer from a raster graphics editor (such as GIMP), through an editing interface, and then being able
to get the data back in scilab. Other objectives include the use of OpenGL for
speeding up (raster) graphics rendering in general, but always
focusing on interactive features and flexible displays. Each pixel should be
efficiently displayed, not only with traditional OpenGL functionality such as pan and zooming,
but most importantly with the ability of having custom ''markers'' to overlay on
the pixels in a fast way. Many image processing algorithms require pixels to be
marked in order to be debugged or animated.

'''Suggested Roadmap:''' 1) Compile scilab from source and understand the
graphics branch from Git; 2) See what has already been done, by carrying out
minor changes in the code and contributing bugfixes as a starter project
3) Code the visual selection of individual pixels, and outputting pixel
properties (which can be a complex data structure) into a scilab variable.
4) Optimize the speed of the image display
4) Improve the inspection of individual pixels with a tooltip
5) Code the display of individual pixels with custom markers, in a fast way
using OpenGL.
6) Finalize a complete fast and flexible display for image/raster data in
Scilab. Incorporate it into a full-fledged fast <tt>imshow</tt> function in SIP,
the Scilab Image Processing toolbox.

[[Imagem:Agora2.png|right|bottom|alt=Ágora Delibera]]

Envisioning direct democracy, this simple deliberation algorithm has been used in different forms by collectives and in software. From a PHP or Django ''hacksware'' to state of art direct democracy as is Delibera, from [http://www.ethymos.com.br Ethymos], a LabMacambira.sf.net partner and co-worker. In fact it is in use by ONU in almost 90 countries for 'habitation rights'. There is also an interesting LabMacambira.sf.net REST version already being tested and an official release o Delibera, from Ethymos partnerts, envisioning this year's election for mayors and councillors. There is a nacional alliance dedicated to direct democracy
going on and writing the [http://pontaopad.me/cartademocraciadireta Open Democracy Letter] which encourage and support
the use of Agora Delibera's mechanisms and codes for representative mandates and public sphere.

'''Objectives:''' Enhance REST deliberation tool to acceptable standards of use for elected representatives. Explore
Ágora Communs; ''hacksware'' to implement and test deliberation modes. With permission to viewing and posting. Test and
implement email, SMS, etc interfaces to Ethymos' Delibera.

'''Suggested Roadmap:''' Study ágora delibera's [https://github.com/teiacasadecriacao/agora-communs/wiki simple mechanism for deliberation].
Get in touch with ongoing [http://wiki.nosdigitais.teia.org.br/GT-Web#.C3.81gora_Communs_.28atual_.C3.81gora_Delibera.29 team and code].
With current development team, choose core features to better apps. Work close with team in irc channel #labmacambira and
maybe try working with [[AA]] as methodology and documentation.

== reacPad ==

We are planning to create a plugin to [http://etherpad.org EtherPad] that makes possible to run JavaScript (and maybe other languages) inside of EtherPads and to be programmable collaborative the same way EtherPad already does for common text.

Important to say that EtherPad is an interesting tool to civil society. With pads we are creating logs for reunions and documents of many kinds (take a look at our page [[Epads]]). It is interesting to take a look at [http://worrydream.com/Tangle/ Bret Victor works on "reactive documents"]. It is a kind of documents we are interested to implement using pads.

'''Objective:''': Create a plugin to [http://beta.etherpad.org EtherPad Lite] (the [[http://nodejs.org node.js]] port of EtherPad) to make possible to embed JavaScript scripts inside a pad.

'''Suggested Roadmap:''' 1) Study the EtherPad Lite architecture; 2) Be part of EtherPad Lite maillist and IRC channel and review the status of plugins development. As we know, today there is not a plugin system for EtherPad Lite, so there will be a task to create a first prototype of a plugin to the system; 3) Develop the plugin inside the plugin system to embed the scripts; 4)

ABeatTracker is a music software for real time execution of specialized macros
that play rythmic patterns with samples. Its internal module ABeatDetector (ABD),
is a rythmic analiser oriented towards indicating periodicities (symmetryc overal duration cells) in a
tapped in rythm. Its porpuse is to indicate musical cells and successions
that can be used immediatelly in ABT, making it possible to really
play live indicating structures that makes sense and develops what your
partner or base is playing.

'''Objectives:''' open for student proposal. Would be really good if ABD and ABT where finaly conected and
ABT could then use ABD's rythmic analysis. Also, ABT could have a Vi or Emacs interface
for live performance with approppriate shortcuts and abbreviations for musical code
execussion.

'''Roadmap:''' while open for student creativity, musical execution of the code
will reveal hacks that creates interesting musical structures. In a way or another,
it would be good so recover or redesign ABD's code (it has been schatched or broken) and
its communication with ABT.

Also, creating 'presets' and abreviations in Vi or Emacs
will provide lots of sound banks and 'musical set' examples. This ideally leads to further
development of livecoding interfaces in Emacs and Vi.

[http://toplap.org Livecoding] is an alternative way to compose and interpret music in real-time. The performer/composer plays on a laptop and shows your screen to the public, making them part of the performance and even understanding what the musician is really doing to generate that weird sounds. Livecoders commonly use general domain languages or creates their own computer music languages. Vivace is an attempt to create a Livecoding language that runs in the Open Web using the new [https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html Web Audio] and [https://wiki.mozilla.org/Audio_Data_API Audio Data] APIs.

'''Objective:''' Continue to add features to Vivace, a Livecoding language that runs on Web browsers.

'''Suggested Roadmap:''' 1) Understand the architecture of Vivace and [http://github.com/oampo/Audiolet Audiolet] (the awesome JavaScript Audio lib created by Joe Turner); 2) Understand features specified at TODO and present at other languages like [http://www.ixi-audio.net/content/software.html ixi lang] and ABT/ABD; 3) Implement the features; 4) Screencast performances using Vivace, maybe public ones.

== Permanent Conference ==
[[Imagem:Conf-perm2.png|right|bottom|alt=Per]]

Every year in Brazil we have the Conference for Defense of Children Rights along all the country. This
are ephemeral reunions, that can benefit alot from a good platform for permanent discussion.

What happens when the conference end? Where the ideas discussed at the conference goes and whats happening about it? Permanent Conference is a Web application to collect knowledge generated on these conferences and to make sure they will be available to all the people.

'''Objective:''' Continue the implementation of the Django application Permanent Conference

'''Suggested Roadmap:''' 1) Read the code already written for the application. It was written in Django, so it is good to have a minor knowledge about that; 2) Understand the [ missed features] and bugs around. Trac is a good point to start; 3) Implement the features; 4) Test with people from Pontos de Cultura from Brazil.

== SOS ==
[[Imagem:Sos2.png|right|bottom|alt=SOS]]

"Saúde Olha Sabedoria" (or Health, Look! Knowledge) is a Web application to collect popular tips around human health. People can also learn how to use popular knowledge to cure their deceases. We believe that softwares like SOS are an interesting way to preserve the culture of a nation and spread it to the others.

'''Objective:''' Fix some bugs on SOS and extend the concept to other areas, creating a knowledge base around popular culture

'''Suggested Roadmap:''' 1) Understand SOS architecture. It was written in Python using Django, so it is important to have a minor knowledge of these technologies; 2) Look at our Trac for bugs related in SOS and fix them; 3) Look for new features. The Trac is again a good start; 4) Extend the SOS to allow the insertion of other kinds of knowledge, not just related with health; 4) Test the platform with people of Pontos de Cultura and collect their feedback

='''UPDATE (2013):'''=

A total of 11 participants in GSoC 2012 were directly related to [http://labmacambira.sf.net LabMacambira]. This was achieved by mentoring together with (other) GSoC 2012 orgs such as [http://www.google-melange.com/gsoc/org/google/gsoc2012/e_cidadania e-cidadania] and [[Scilab]]. Members of [http://labmacambira.sf.net] also took part as students, for Mozilla and the mentioned orgs. This participation focused in projects related to [[AA]], digital deliberation methods, [[Scilab]] and [[Mozilla]][http://maverickranter.blogspot.com.br/2012/05/5-bolsas-do-google-summer-of-code-dadas.html].

Here is the list of the mentors/students of LabMacambira.sf.net and their respective projects:

LabMacambira.sf.net was not selected as a GSoC 2012 organization. However, we are very proud and thankful for all the vouchers and recommendation letters written for us (and forwarded to Google) during the summer of 2012. These letters are listed in the following section.

=Vouchers and Recommendations=

There are some honorable documents there were written to Google
itself, as recommendations and vouchers of our work. First of all,
there is this letter from Célio Turino[1], idealizer of 'pontos de cultura',
a Brazilian federal program that reaches 8,4 million people (5% of Brazilian
population). It is a formal gift from him to LabMacambira and a homage to
Cleodon Silva (1949 - 2011), who inspired LabMacambira.sf.net.
The is also a formal document from the National Commission of the almost 4000
pontos which tells a little bit more about LabMacambira.sf.net's importance
for Cultura Viva[2]. The third letter came Ethymos, a partner enterprise
(LabMacambira.sf.net is not an enterprise) that joins LabMacambira.sf.net
in a direct democracy and free medias protagonist network in Brazil.
The fourth letter came from Puraqué, a collective based in Santarém,
in the Amazonian region [4]. Worth noticing that both Amazonian Free Software
Forum (FASOL) and Amazonian Forum of Digital Culture are in the third edition,
and the text might suggest otherwise.

== AA (client) ==
[[Imagem:Aa-macaco.png|right|bottom|alt=AA Console Client]]

[[AA]] is a social system for coordinating
distributed teamwork where each participant stays logged for at least 2 hours a day,
publicly microblogging
their development activities related to assigned tickets (self-assigned or team-assigned). At the end of each
daly session, a video log is recorded and [http://vimeo.com/channels/labmacambira uploaded to a public video channel],
the text log is also [http://hera.ethymos.com.br:1080/paainel/casca/ published on the Web] and is
peer-validated for quality. The AA system and its underlying software
engineering methodology enables self-funding for distributed collectives of
developers working on FLOSS projects.

'''Objective:''' AA is a distributed system following a client-server
architecture. Each AA client is a Python application in textual or GTK+ form that communicates
with the AA server, the web instance. Through the client each developer can send
messages and log his activities. Currently, AA client is a simple program
written to run in Linux. Being a software that aims to be used by everyone
it would be important to be multiplatform (perhaps as a web client) and to have
additional functionalities such as better Trac and Git log integration, RSS/Google+
developer feeds, and automatic videolog watermarking. A student working on AA could
work on these features for the program.

[[Imagem:Aapp2.png|right|bottom|alt=AA GTK2 Frontend]]

'''Suggested Roadmap:''' 1) Understand the AA architecture; 2) Use AA in its
current form to understand, as a developer working in a collaborative group,
what features are most needed. These features could be implemented during the
summer or documented for a future developers; 3) Research about how to make AA
multiplatform - we are planning to make a Web client; 4) Implement the features
on the TODO of the project and some of the features listed by yourself if
possible. 5) write a paper about the AA methodology and experiences with the
implemented system.

== pAAinel (AA server) ==
[[Imagem:Aa2.png|right|bottom|alt=AA]]

AA is a distributed system for coordinating decentralized teamwork, as described above. We need to develop the server side of AA, which already includes an aggregator of logs, and a master aggregator of all the team information in a dashboard which is similar to iGoogle: [http://hera.ethymos.com.br:1080/paainel/casca/ pAAinel]. Currently, [http://hera.ethymos.com.br:1080/paainel/casca/ pAAinel] merely displays information about logs registered by the AA server, together with complementary information, like a recent irc log, tickets and last screencasts and code commits.

'''Objective:''' We desire to rewrite the AA microblog server (actually written in PHP) as a module inside pAAinel, a Django application.

'''Suggested Roadmap:''' 1) Understand the current AA architecture; 2) Read both pAAinel (made in Django) and AA server (in PHP) code and associated documentation, planning how to rewrite AA server as a module inside pAAinel; 3) To develop and test the new pAAinel together with members of LabMacambira; 4) Continuouslly document the process.

== [[AirHackTable]] ==
[[Imagem:Aht.png|right|bottom|alt=AHT]]

The [[AirHackTable]] is an art project - an interactive music instrument based on advanced computer vision algorithms that track flying origamis, associating their trajectories, color, and shape to different musical properties. The recycled coolers inside a cardboard table (itself an origami) generates a layer of air on top of which colored origamis float around and make track patterns depending on their geometry. A set of webcams on top then captures those patterns through our own color detection and 3D reconstruction algorithms, and then generate and modulate sounds based on the trajectory, color, and shape of the origamis. Many are the technological spinoffs of this project, most of which were accepted officially into well-established software such as the [[Pd]]/Gem real time multimedia programming system and [[Scilab]].

'''Objective:''' The [[AHT]] project is an opportunity to develop and spread cutting-edge technology in a playful manner, which may seem otherwise too hard/unapproachable.
We plan to improve geometric recognition to be used for generating sounds for modulating voices that are in agreement with the geometry of the origami. The goal, then, is to implement algorithms for 3D edge/curve reconstuction from the mentor's research, in order to recover the origami's edges in 3D, thus recovering the true geometry of the origami. Other techniques such as 2D recognition of origami silhouettes should also be developed. This playful project is expected to generate technological spinoffs which will be incorporated into other well-established FLOSS projects such as [[Pd]], [[Scilab]], [[OpenCV]], and [http://vxl.sf.net VXL]. Some of the Google projects that can benefit from the underlying machine vision technology include Google Streetview, Google Book scanning, Google Image Search, and Youtube.

'''Suggested Roadmap:''' 1) compile and run the current system after downloading the large set of repositories and watching our screencasts; 2) brush up on the background: [[Pd]], [[C++]],
and Computer Vision, by talking to the mentors and watching our screencasts; 3) get the 3D reconstruction system up and running isolatedly 4) optimize the system to run in real time
5) incorporate the 3D reconstruction system into the [[AHT]] system; 6) write up documentation and papers on the core technologies.

== [[SIP]] + [[Scilab]] ==

[[Imagem:SIP_whitebg.png|right|bottom|alt=SIP toolbox]]
[[Imagem:Leptonica.jpg|right|bottom|alt=Leptonica Image Processing Library from Google]]

[http://siptoolbox.sf.net SIP] stands for [[Scilab]] Image Processing toolbox. [[SIP]] performs imaging tasks such
as filtering, blurring, edge detection, thresholding, histogram manipulation,
segmentation, mathematical morphology, color image processing, etc. It leverages
the extremely simple [[Scilab]] programming environment for prototyping complex computer
vision solutions.

'''Objective:''' First, to add functionality to the Google FLOSS project
[http://www.leptonica.com Leptonica] and interface most of this C library with Scilab.
Second, to throroughly document this library. Google projects that will most
benefit from this effort include Google Book search and Google Image Search.

'''Suggested Roadmap:''' 1) Run leptonica and SIP; 2) make a contribution to
Leptonica (at least a simple bugfix), which will help the student get started;
3) write the necessary C infrastructure to interface Leptonica
image structures with Scilab matrices
4) interface a Leptonica functionality with Scilab and document it thoroghly
5) repeat 4, prioritizing functions that can only be found in Leptonica.

== [[Scilab]] Interactive Visualization ==

[[Imagem:Scilab_logo.gif|200px|right|bottom|alt=Scilab]]

[[Scilab]] is a free rapid prototyping environment for numerical algorithm
development, similar to Octave, Matlab and (to some extent) Python. A powerful
interactive GUI is one of the main features that makes Scilab stand out from
Python and Octave in their current form. This is a central feature of scilab,
specially for large-scale data mining; the capability of interactively
exploring visual data to/from the scilab language is a fundamental part of
the process of prototyping a solution to a given problem.

'''Objective:''' This project aims to improve interactive data exploration and
editing features of Scilab graphics. In other words, the aim is to make plots
more interactive with data (clicking + deleting a curve, clicking + obtaining
data from a curve, etc). Primary objectives include: to improve tooltip
functionality, to improve editing capabilities, and to improve selection of
plots and inspection of values into a scilab varialble, both in 2D and 3D. This
basically means treating the scilab graphic window as a vector graphics, through
an editing interface, and then being able to get the data back in scilab. Other
objectives include the use of OpenGL for speeding up the speed of (vector)
graphics rendering in general, but always focusing on interactive features
(dragging points from a plot curve and obtaining the corresponding data, etc)

'''Suggested Roadmap:''' 1) Compile scilab from source and understand the
graphics branch from Git; 2) See what has already been done, by carrying out
minor changes in the code and contributing bugfixes as a starter project
3) Code the visual selection of individual points and curves and 3D surfaces, and outputting curve properties into a
scilab variable.
4) Improve the inspection of individual curve/surface elements/points with a tooltip
5) Code the deletion of isolated points and curves from a plot
6) Code point and curve editing functionality: click and drag a point will
change its (x,y) data. Similar for curves and surfaces, but dragging each
individual sample points independently, or even Bezier-style functionality could be
added.

== [[Scilab]] Fast and Flexible Image (Raster) Display ==
[[Imagem:SIP-shot4.png|250px|right|bottom|alt=Scilab]]

[[Scilab]] is a free rapid prototyping environment for numerical algorithm
development, similar to Octave, Matlab and (to some extent) Python. A powerful
interactive GUI for displaying raster data (matrices, images, marked pixels,
etc) would be one of the main features that makes Scilab stand out from Python and
Octave in their current form. Interactive graphics is a central feature of
scilab, specially for developing new image processing algorithms; the capability
of interactively exploring raster visual data to/from the Scilab language is a
fundamental part of the process of prototyping and debugging a new algorithmic
solution to a given image analysis problem.

'''Objective:''' This project aims to improve interactive '''raster''' data exploration and
editing features of Scilab graphics. In other words, the aim is to make image
display more interactive with data (clicking + modifying a pixel, clicking + obtaining
associated data from a pixel, etc). Primary objectives include: to improve tooltip
functionality, to improve display capabilities, and to improve selection of
pixels and inspection of their values and associated data into a scilab
varialble, both in 2D and 3D. This basically means treating the scilab graphic
window as a buffer from a raster graphics editor (such as GIMP), through an editing interface, and then being able
to get the data back in scilab. Other objectives include the use of OpenGL for
speeding up (raster) graphics rendering in general, but always
focusing on interactive features and flexible displays. Each pixel should be
efficiently displayed, not only with traditional OpenGL functionality such as pan and zooming,
but most importantly with the ability of having custom ''markers'' to overlay on
the pixels in a fast way. Many image processing algorithms require pixels to be
marked in order to be debugged or animated.

'''Suggested Roadmap:''' 1) Compile scilab from source and understand the
graphics branch from Git; 2) See what has already been done, by carrying out
minor changes in the code and contributing bugfixes as a starter project
3) Code the visual selection of individual pixels, and outputting pixel
properties (which can be a complex data structure) into a scilab variable.
4) Optimize the speed of the image display
4) Improve the inspection of individual pixels with a tooltip
5) Code the display of individual pixels with custom markers, in a fast way
using OpenGL.
6) Finalize a complete fast and flexible display for image/raster data in
Scilab. Incorporate it into a full-fledged fast <tt>imshow</tt> function in SIP,
the Scilab Image Processing toolbox.

[[Imagem:Agora2.png|right|bottom|alt=Ágora Delibera]]

Envisioning direct democracy, this simple deliberation algorithm has been used in different forms by collectives and in software. From a PHP or Django ''hacksware'' to state of art direct democracy as is Delibera, from [http://www.ethymos.com.br Ethymos], a LabMacambira.sf.net partner and co-worker. In fact it is in use by ONU in almost 90 countries for 'habitation rights'. There is also an interesting LabMacambira.sf.net REST version already being tested and an official release o Delibera, from Ethymos partnerts, envisioning this year's election for mayors and councillors. There is a nacional alliance dedicated to direct democracy
going on and writing the [http://pontaopad.me/cartademocraciadireta Open Democracy Letter] which encourage and support
the use of Agora Delibera's mechanisms and codes for representative mandates and public sphere.

'''Objectives:''' Enhance REST deliberation tool to acceptable standards of use for elected representatives. Explore
Ágora Communs; ''hacksware'' to implement and test deliberation modes. With permission to viewing and posting. Test and
implement email, SMS, etc interfaces to Ethymos' Delibera.

'''Suggested Roadmap:''' Study ágora delibera's [https://github.com/teiacasadecriacao/agora-communs/wiki simple mechanism for deliberation].
Get in touch with ongoing [http://wiki.nosdigitais.teia.org.br/GT-Web#.C3.81gora_Communs_.28atual_.C3.81gora_Delibera.29 team and code].
With current development team, choose core features to better apps. Work close with team in irc channel #labmacambira and
maybe try working with [[AA]] as methodology and documentation.

== reacPad ==

We are planning to create a plugin to [http://etherpad.org EtherPad] that makes possible to run JavaScript (and maybe other languages) inside of EtherPads and to be programmable collaborative the same way EtherPad already does for common text.

Important to say that EtherPad is an interesting tool to civil society. With pads we are creating logs for reunions and documents of many kinds (take a look at our page [[Epads]]). It is interesting to take a look at [http://worrydream.com/Tangle/ Bret Victor works on "reactive documents"]. It is a kind of documents we are interested to implement using pads.

'''Objective:''': Create a plugin to [http://beta.etherpad.org EtherPad Lite] (the [[http://nodejs.org node.js]] port of EtherPad) to make possible to embed JavaScript scripts inside a pad.

'''Suggested Roadmap:''' 1) Study the EtherPad Lite architecture; 2) Be part of EtherPad Lite maillist and IRC channel and review the status of plugins development. As we know, today there is not a plugin system for EtherPad Lite, so there will be a task to create a first prototype of a plugin to the system; 3) Develop the plugin inside the plugin system to embed the scripts; 4)

'''Repos:''': The EtherPad Lite GIT repos is a good starting point https://github.com/Pita/etherpad-lite

ABeatTracker is a music software for real time execution of specialized macros
that play rythmic patterns with samples. Its internal module ABeatDetector (ABD),
is a rythmic analiser oriented towards indicating periodicities (symmetryc overal duration cells) in a
tapped in rythm. Its porpuse is to indicate musical cells and successions
that can be used immediatelly in ABT, making it possible to really
play live indicating structures that makes sense and develops what your
partner or base is playing.

'''Objectives:''' open for student proposal. Would be really good if ABD and ABT where finaly conected and
ABT could then use ABD's rythmic analysis. Also, ABT could have a Vi or Emacs interface
for live performance with approppriate shortcuts and abbreviations for musical code
execussion.

'''Roadmap:''' while open for student creativity, musical execution of the code
will reveal hacks that creates interesting musical structures. In a way or another,
it would be good so recover or redesign ABD's code (it has been schatched or broken) and
its communication with ABT.

Also, creating 'presets' and abreviations in Vi or Emacs
will provide lots of sound banks and 'musical set' examples. This ideally leads to further
development of livecoding interfaces in Emacs and Vi.

'''Languages:''' Python and ChucK comunicating via OSC mainly, vi and Emacs scripting too

[http://toplap.org Livecoding] is an alternative way to compose and interpret music in real-time. The performer/composer plays on a laptop and shows your screen to the public, making them part of the performance and even understanding what the musician is really doing to generate that weird sounds. Livecoders commonly use general domain languages or creates their own computer music languages. Vivace is an attempt to create a Livecoding language that runs in the Open Web using the new [https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html Web Audio] and [https://wiki.mozilla.org/Audio_Data_API Audio Data] APIs.

'''Objective:''' Continue to add features to Vivace, a Livecoding language that runs on Web browsers.

'''Suggested Roadmap:''' 1) Understand the architecture of Vivace and [http://github.com/oampo/Audiolet Audiolet] (the awesome JavaScript Audio lib created by Joe Turner); 2) Understand features specified at TODO and present at other languages like [http://www.ixi-audio.net/content/software.html ixi lang] and ABT/ABD; 3) Implement the features; 4) Screencast performances using Vivace, maybe public ones.

IRC bots are social technology by nature. Autonomous software agents that can talk directly with people are powerful tools to understand their needs. We visualize IRC as a direct channel to communicate with people. Macambot, Lalenia and coBots are Supybots, Python IRC robots we want to continuously develop as agents that can collect software features proposed by the people and interact with them.

'''Objective:''' Continue the deveopment of the Supybots Macambot, Lalenia and coBots.

'''Suggested Roadmap:''' 1) Understand Supybot and its plugins; 2) Develop a test plugin to interact with people collecting their suggestions as software features; 3) Study Python NLTK (Natural Language Toolkit); 4) Improve the plugin with natural language processing, to talk with people "as a human"; 5) Create a Trac plugin to add bug and features entries based on the IRC bots data base of conversation with people that use #labmacambira at irc.freenode.net and/or other channels and IRC servers

== Permanent Conference ==
[[Imagem:Conf-perm2.png|right|bottom|alt=Per]]

Every year in Brazil we have the Conference for Defense of Children Rights along all the country. This
are ephemeral reunions, that can benefit alot from a good platform for permanent discussion.

What happens when the conference end? Where the ideas discussed at the conference goes and whats happening about it? Permanent Conference is a Web application to collect knowledge generated on these conferences and to make sure they will be available to all the people.

'''Objective:''' Continue the implementation of the Django application Permanent Conference

'''Suggested Roadmap:''' 1) Read the code already written for the application. It was written in Django, so it is good to have a minor knowledge about that; 2) Understand the [ missed features] and bugs around. Trac is a good point to start; 3) Implement the features; 4) Test with people from Pontos de Cultura from Brazil.

== SOS ==
[[Imagem:Sos2.png|right|bottom|alt=SOS]]

"Saúde Olha Sabedoria" (or Health, Look! Knowledge) is a Web application to collect popular tips around human health. People can also learn how to use popular knowledge to cure their deceases. We believe that softwares like SOS are an interesting way to preserve the culture of a nation and spread it to the others.

'''Objective:''' Fix some bugs on SOS and extend the concept to other areas, creating a knowledge base around popular culture

'''Suggested Roadmap:''' 1) Understand SOS architecture. It was written in Python using Django, so it is important to have a minor knowledge of these technologies; 2) Look at our Trac for bugs related in SOS and fix them; 3) Look for new features. The Trac is again a good start; 4) Extend the SOS to allow the insertion of other kinds of knowledge, not just related with health; 4) Test the platform with people of Pontos de Cultura and collect their feedback

='''UPDATE (2013):'''=

A total of 11 participants in GSoC 2012 were directly related to [http://labmacambira.sf.net LabMacambira]. This was achieved by mentoring together with (other) GSoC 2012 orgs such as [http://www.google-melange.com/gsoc/org/google/gsoc2012/e_cidadania e-cidadania] and [[Scilab]]. Members of [http://labmacambira.sf.net] also took part as students, for Mozilla and the mentioned orgs. This participation focused in projects related to [[AA]], digital deliberation methods, [[Scilab]] and [[Mozilla]][http://maverickranter.blogspot.com.br/2012/05/5-bolsas-do-google-summer-of-code-dadas.html].

Here is the list of the mentors/students of LabMacambira.sf.net and their respective projects:

LabMacambira.sf.net was not selected as a GSoC 2012 organization. However, we are very proud and thankful for all the vouchers and recommendation letters written for us (and forwarded to Google) during the summer of 2012. These letters are listed bellow:

=Vouchers and Recommendations=

There are some honorable documents there were written to Google
itself, as recommendations and vouchers of our work. First of all,
there is this letter from Célio Turino[1], idealizer of 'pontos de cultura',
a Brazilian federal program that reaches 8,4 million people (5% of Brazilian
population). It is a formal gift from him to LabMacambira and a homage to
Cleodon Silva (1949 - 2011), who inspired LabMacambira.sf.net.
The is also a formal document from the National Commission of the almost 4000
pontos which tells a little bit more about LabMacambira.sf.net's importance
for Cultura Viva[2]. The third letter came Ethymos, a partner enterprise
(LabMacambira.sf.net is not an enterprise) that joins LabMacambira.sf.net
in a direct democracy and free medias protagonist network in Brazil.
The fourth letter came from Puraqué, a collective based in Santarém,
in the Amazonian region [4]. Worth noticing that both Amazonian Free Software
Forum (FASOL) and Amazonian Forum of Digital Culture are in the third edition,
and the text might suggest otherwise.

== AA (client) ==
[[Imagem:Aa-macaco.png|right|bottom|alt=AA Console Client]]

[[AA]] is a social system for coordinating
distributed teamwork where each participant stays logged for at least 2 hours a day,
publicly microblogging
their development activities related to assigned tickets (self-assigned or team-assigned). At the end of each
daly session, a video log is recorded and [http://vimeo.com/channels/labmacambira uploaded to a public video channel],
the text log is also [http://hera.ethymos.com.br:1080/paainel/casca/ published on the Web] and is
peer-validated for quality. The AA system and its underlying software
engineering methodology enables self-funding for distributed collectives of
developers working on FLOSS projects.

'''Objective:''' AA is a distributed system following a client-server
architecture. Each AA client is a Python application in textual or GTK+ form that communicates
with the AA server, the web instance. Through the client each developer can send
messages and log his activities. Currently, AA client is a simple program
written to run in Linux. Being a software that aims to be used by everyone
it would be important to be multiplatform (perhaps as a web client) and to have
additional functionalities such as better Trac and Git log integration, RSS/Google+
developer feeds, and automatic videolog watermarking. A student working on AA could
work on these features for the program.

[[Imagem:Aapp2.png|right|bottom|alt=AA GTK2 Frontend]]

'''Suggested Roadmap:''' 1) Understand the AA architecture; 2) Use AA in its
current form to understand, as a developer working in a collaborative group,
what features are most needed. These features could be implemented during the
summer or documented for a future developers; 3) Research about how to make AA
multiplatform - we are planning to make a Web client; 4) Implement the features
on the TODO of the project and some of the features listed by yourself if
possible. 5) write a paper about the AA methodology and experiences with the
implemented system.

== pAAinel (AA server) ==
[[Imagem:Aa2.png|right|bottom|alt=AA]]

AA is a distributed system for coordinating decentralized teamwork, as described above. We need to develop the server side of AA, which already includes an aggregator of logs, and a master aggregator of all the team information in a dashboard which is similar to iGoogle: [http://hera.ethymos.com.br:1080/paainel/casca/ pAAinel]. Currently, [http://hera.ethymos.com.br:1080/paainel/casca/ pAAinel] merely displays information about logs registered by the AA server, together with complementary information, like a recent irc log, tickets and last screencasts and code commits.

'''Objective:''' We desire to rewrite the AA microblog server (actually written in PHP) as a module inside pAAinel, a Django application.

'''Suggested Roadmap:''' 1) Understand the current AA architecture; 2) Read both pAAinel (made in Django) and AA server (in PHP) code and associated documentation, planning how to rewrite AA server as a module inside pAAinel; 3) To develop and test the new pAAinel together with members of LabMacambira; 4) Continuouslly document the process.

== [[AirHackTable]] ==
[[Imagem:Aht.png|right|bottom|alt=AHT]]

The [[AirHackTable]] is an art project - an interactive music instrument based on advanced computer vision algorithms that track flying origamis, associating their trajectories, color, and shape to different musical properties. The recycled coolers inside a cardboard table (itself an origami) generates a layer of air on top of which colored origamis float around and make track patterns depending on their geometry. A set of webcams on top then captures those patterns through our own color detection and 3D reconstruction algorithms, and then generate and modulate sounds based on the trajectory, color, and shape of the origamis. Many are the technological spinoffs of this project, most of which were accepted officially into well-established software such as the [[Pd]]/Gem real time multimedia programming system and [[Scilab]].

'''Objective:''' The [[AHT]] project is an opportunity to develop and spread cutting-edge technology in a playful manner, which may seem otherwise too hard/unapproachable.
We plan to improve geometric recognition to be used for generating sounds for modulating voices that are in agreement with the geometry of the origami. The goal, then, is to implement algorithms for 3D edge/curve reconstuction from the mentor's research, in order to recover the origami's edges in 3D, thus recovering the true geometry of the origami. Other techniques such as 2D recognition of origami silhouettes should also be developed. This playful project is expected to generate technological spinoffs which will be incorporated into other well-established FLOSS projects such as [[Pd]], [[Scilab]], [[OpenCV]], and [http://vxl.sf.net VXL]. Some of the Google projects that can benefit from the underlying machine vision technology include Google Streetview, Google Book scanning, Google Image Search, and Youtube.

'''Suggested Roadmap:''' 1) compile and run the current system after downloading the large set of repositories and watching our screencasts; 2) brush up on the background: [[Pd]], [[C++]],
and Computer Vision, by talking to the mentors and watching our screencasts; 3) get the 3D reconstruction system up and running isolatedly 4) optimize the system to run in real time
5) incorporate the 3D reconstruction system into the [[AHT]] system; 6) write up documentation and papers on the core technologies.

== [[SIP]] + [[Scilab]] ==

[[Imagem:SIP_whitebg.png|right|bottom|alt=SIP toolbox]]
[[Imagem:Leptonica.jpg|right|bottom|alt=Leptonica Image Processing Library from Google]]

[http://siptoolbox.sf.net SIP] stands for [[Scilab]] Image Processing toolbox. [[SIP]] performs imaging tasks such
as filtering, blurring, edge detection, thresholding, histogram manipulation,
segmentation, mathematical morphology, color image processing, etc. It leverages
the extremely simple [[Scilab]] programming environment for prototyping complex computer
vision solutions.

'''Objective:''' First, to add functionality to the Google FLOSS project
[http://www.leptonica.com Leptonica] and interface most of this C library with Scilab.
Second, to throroughly document this library. Google projects that will most
benefit from this effort include Google Book search and Google Image Search.

'''Suggested Roadmap:''' 1) Run leptonica and SIP; 2) make a contribution to
Leptonica (at least a simple bugfix), which will help the student get started;
3) write the necessary C infrastructure to interface Leptonica
image structures with Scilab matrices
4) interface a Leptonica functionality with Scilab and document it thoroghly
5) repeat 4, prioritizing functions that can only be found in Leptonica.

== [[Scilab]] Interactive Visualization ==

[[Imagem:Scilab_logo.gif|200px|right|bottom|alt=Scilab]]

[[Scilab]] is a free rapid prototyping environment for numerical algorithm
development, similar to Octave, Matlab and (to some extent) Python. A powerful
interactive GUI is one of the main features that makes Scilab stand out from
Python and Octave in their current form. This is a central feature of scilab,
specially for large-scale data mining; the capability of interactively
exploring visual data to/from the scilab language is a fundamental part of
the process of prototyping a solution to a given problem.

'''Objective:''' This project aims to improve interactive data exploration and
editing features of Scilab graphics. In other words, the aim is to make plots
more interactive with data (clicking + deleting a curve, clicking + obtaining
data from a curve, etc). Primary objectives include: to improve tooltip
functionality, to improve editing capabilities, and to improve selection of
plots and inspection of values into a scilab varialble, both in 2D and 3D. This
basically means treating the scilab graphic window as a vector graphics, through
an editing interface, and then being able to get the data back in scilab. Other
objectives include the use of OpenGL for speeding up the speed of (vector)
graphics rendering in general, but always focusing on interactive features
(dragging points from a plot curve and obtaining the corresponding data, etc)

'''Suggested Roadmap:''' 1) Compile scilab from source and understand the
graphics branch from Git; 2) See what has already been done, by carrying out
minor changes in the code and contributing bugfixes as a starter project
3) Code the visual selection of individual points and curves and 3D surfaces, and outputting curve properties into a
scilab variable.
4) Improve the inspection of individual curve/surface elements/points with a tooltip
5) Code the deletion of isolated points and curves from a plot
6) Code point and curve editing functionality: click and drag a point will
change its (x,y) data. Similar for curves and surfaces, but dragging each
individual sample points independently, or even Bezier-style functionality could be
added.

== [[Scilab]] Fast and Flexible Image (Raster) Display ==
[[Imagem:SIP-shot4.png|250px|right|bottom|alt=Scilab]]

[[Scilab]] is a free rapid prototyping environment for numerical algorithm
development, similar to Octave, Matlab and (to some extent) Python. A powerful
interactive GUI for displaying raster data (matrices, images, marked pixels,
etc) would be one of the main features that makes Scilab stand out from Python and
Octave in their current form. Interactive graphics is a central feature of
scilab, specially for developing new image processing algorithms; the capability
of interactively exploring raster visual data to/from the Scilab language is a
fundamental part of the process of prototyping and debugging a new algorithmic
solution to a given image analysis problem.

'''Objective:''' This project aims to improve interactive '''raster''' data exploration and
editing features of Scilab graphics. In other words, the aim is to make image
display more interactive with data (clicking + modifying a pixel, clicking + obtaining
associated data from a pixel, etc). Primary objectives include: to improve tooltip
functionality, to improve display capabilities, and to improve selection of
pixels and inspection of their values and associated data into a scilab
varialble, both in 2D and 3D. This basically means treating the scilab graphic
window as a buffer from a raster graphics editor (such as GIMP), through an editing interface, and then being able
to get the data back in scilab. Other objectives include the use of OpenGL for
speeding up (raster) graphics rendering in general, but always
focusing on interactive features and flexible displays. Each pixel should be
efficiently displayed, not only with traditional OpenGL functionality such as pan and zooming,
but most importantly with the ability of having custom ''markers'' to overlay on
the pixels in a fast way. Many image processing algorithms require pixels to be
marked in order to be debugged or animated.

'''Suggested Roadmap:''' 1) Compile scilab from source and understand the
graphics branch from Git; 2) See what has already been done, by carrying out
minor changes in the code and contributing bugfixes as a starter project
3) Code the visual selection of individual pixels, and outputting pixel
properties (which can be a complex data structure) into a scilab variable.
4) Optimize the speed of the image display
4) Improve the inspection of individual pixels with a tooltip
5) Code the display of individual pixels with custom markers, in a fast way
using OpenGL.
6) Finalize a complete fast and flexible display for image/raster data in
Scilab. Incorporate it into a full-fledged fast <tt>imshow</tt> function in SIP,
the Scilab Image Processing toolbox.

[[Imagem:Agora2.png|right|bottom|alt=Ágora Delibera]]

Envisioning direct democracy, this simple deliberation algorithm has been used in different forms by collectives and in software. From a PHP or Django ''hacksware'' to state of art direct democracy as is Delibera, from [http://www.ethymos.com.br Ethymos], a LabMacambira.sf.net partner and co-worker. In fact it is in use by ONU in almost 90 countries for 'habitation rights'. There is also an interesting LabMacambira.sf.net REST version already being tested and an official release o Delibera, from Ethymos partnerts, envisioning this year's election for mayors and councillors. There is a nacional alliance dedicated to direct democracy
going on and writing the [http://pontaopad.me/cartademocraciadireta Open Democracy Letter] which encourage and support
the use of Agora Delibera's mechanisms and codes for representative mandates and public sphere.

'''Objectives:''' Enhance REST deliberation tool to acceptable standards of use for elected representatives. Explore
Ágora Communs; ''hacksware'' to implement and test deliberation modes. With permission to viewing and posting. Test and
implement email, SMS, etc interfaces to Ethymos' Delibera.

'''Suggested Roadmap:''' Study ágora delibera's [https://github.com/teiacasadecriacao/agora-communs/wiki simple mechanism for deliberation].
Get in touch with ongoing [http://wiki.nosdigitais.teia.org.br/GT-Web#.C3.81gora_Communs_.28atual_.C3.81gora_Delibera.29 team and code].
With current development team, choose core features to better apps. Work close with team in irc channel #labmacambira and
maybe try working with [[AA]] as methodology and documentation.

== reacPad ==

We are planning to create a plugin to [http://etherpad.org EtherPad] that makes possible to run JavaScript (and maybe other languages) inside of EtherPads and to be programmable collaborative the same way EtherPad already does for common text.

Important to say that EtherPad is an interesting tool to civil society. With pads we are creating logs for reunions and documents of many kinds (take a look at our page [[Epads]]). It is interesting to take a look at [http://worrydream.com/Tangle/ Bret Victor works on "reactive documents"]. It is a kind of documents we are interested to implement using pads.

'''Objective:''': Create a plugin to [http://beta.etherpad.org EtherPad Lite] (the [[http://nodejs.org node.js]] port of EtherPad) to make possible to embed JavaScript scripts inside a pad.

'''Suggested Roadmap:''' 1) Study the EtherPad Lite architecture; 2) Be part of EtherPad Lite maillist and IRC channel and review the status of plugins development. As we know, today there is not a plugin system for EtherPad Lite, so there will be a task to create a first prototype of a plugin to the system; 3) Develop the plugin inside the plugin system to embed the scripts; 4)

'''Repos:''': The EtherPad Lite GIT repos is a good starting point https://github.com/Pita/etherpad-lite

ABeatTracker is a music software for real time execution of specialized macros
that play rythmic patterns with samples. Its internal module ABeatDetector (ABD),
is a rythmic analiser oriented towards indicating periodicities (symmetryc overal duration cells) in a
tapped in rythm. Its porpuse is to indicate musical cells and successions
that can be used immediatelly in ABT, making it possible to really
play live indicating structures that makes sense and develops what your
partner or base is playing.

'''Objectives:''' open for student proposal. Would be really good if ABD and ABT where finaly conected and
ABT could then use ABD's rythmic analysis. Also, ABT could have a Vi or Emacs interface
for live performance with approppriate shortcuts and abbreviations for musical code
execussion.

'''Roadmap:''' while open for student creativity, musical execution of the code
will reveal hacks that creates interesting musical structures. In a way or another,
it would be good so recover or redesign ABD's code (it has been schatched or broken) and
its communication with ABT.

Also, creating 'presets' and abreviations in Vi or Emacs
will provide lots of sound banks and 'musical set' examples. This ideally leads to further
development of livecoding interfaces in Emacs and Vi.

'''Languages:''' Python and ChucK comunicating via OSC mainly, vi and Emacs scripting too

[http://toplap.org Livecoding] is an alternative way to compose and interpret music in real-time. The performer/composer plays on a laptop and shows your screen to the public, making them part of the performance and even understanding what the musician is really doing to generate that weird sounds. Livecoders commonly use general domain languages or creates their own computer music languages. Vivace is an attempt to create a Livecoding language that runs in the Open Web using the new [https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html Web Audio] and [https://wiki.mozilla.org/Audio_Data_API Audio Data] APIs.

'''Objective:''' Continue to add features to Vivace, a Livecoding language that runs on Web browsers.

'''Suggested Roadmap:''' 1) Understand the architecture of Vivace and [http://github.com/oampo/Audiolet Audiolet] (the awesome JavaScript Audio lib created by Joe Turner); 2) Understand features specified at TODO and present at other languages like [http://www.ixi-audio.net/content/software.html ixi lang] and ABT/ABD; 3) Implement the features; 4) Screencast performances using Vivace, maybe public ones.

IRC bots are social technology by nature. Autonomous software agents that can talk directly with people are powerful tools to understand their needs. We visualize IRC as a direct channel to communicate with people. Macambot, Lalenia and coBots are Supybots, Python IRC robots we want to continuously develop as agents that can collect software features proposed by the people and interact with them.

'''Objective:''' Continue the deveopment of the Supybots Macambot, Lalenia and coBots.

'''Suggested Roadmap:''' 1) Understand Supybot and its plugins; 2) Develop a test plugin to interact with people collecting their suggestions as software features; 3) Study Python NLTK (Natural Language Toolkit); 4) Improve the plugin with natural language processing, to talk with people "as a human"; 5) Create a Trac plugin to add bug and features entries based on the IRC bots data base of conversation with people that use #labmacambira at irc.freenode.net and/or other channels and IRC servers

== Permanent Conference ==
[[Imagem:Conf-perm2.png|right|bottom|alt=Per]]

Every year in Brazil we have the Conference for Defense of Children Rights along all the country. This
are ephemeral reunions, that can benefit alot from a good platform for permanent discussion.

What happens when the conference end? Where the ideas discussed at the conference goes and whats happening about it? Permanent Conference is a Web application to collect knowledge generated on these conferences and to make sure they will be available to all the people.

'''Objective:''' Continue the implementation of the Django application Permanent Conference

'''Suggested Roadmap:''' 1) Read the code already written for the application. It was written in Django, so it is good to have a minor knowledge about that; 2) Understand the [ missed features] and bugs around. Trac is a good point to start; 3) Implement the features; 4) Test with people from Pontos de Cultura from Brazil.

== SOS ==
[[Imagem:Sos2.png|right|bottom|alt=SOS]]

"Saúde Olha Sabedoria" (or Health, Look! Knowledge) is a Web application to collect popular tips around human health. People can also learn how to use popular knowledge to cure their deceases. We believe that softwares like SOS are an interesting way to preserve the culture of a nation and spread it to the others.

'''Objective:''' Fix some bugs on SOS and extend the concept to other areas, creating a knowledge base around popular culture

'''Suggested Roadmap:''' 1) Understand SOS architecture. It was written in Python using Django, so it is important to have a minor knowledge of these technologies; 2) Look at our Trac for bugs related in SOS and fix them; 3) Look for new features. The Trac is again a good start; 4) Extend the SOS to allow the insertion of other kinds of knowledge, not just related with health; 4) Test the platform with people of Pontos de Cultura and collect their feedback

A total of 11 participants in GSoC 2012 were directly related to [http://labmacambira.sf.net LabMacambira]. This was achieved by mentoring together with (other) GSoC 2012 orgs such as [http://www.google-melange.com/gsoc/org/google/gsoc2012/e_cidadania e-cidadania] and [[Scilab]]. Members of [http://labmacambira.sf.net] also took part as students, for Mozilla and the mentioned orgs. This participation focused in projects related to [[AA]], digital deliberation methods, [[Scilab]] and [[Mozilla]][http://maverickranter.blogspot.com.br/2012/05/5-bolsas-do-google-summer-of-code-dadas.html].

Here is the list of the mentors/students of LabMacambira.sf.net and their respective projects:

LabMacambira.sf.net was not selected as a GSoC 2012 organization. However, we are very proud and thankful about all the vouchers and recommendation letters were written for us (and forwarded to Google) during summer of 2012. We are listing those letters as follows:

=Vouchers and Recommendations=

There are some honorable documents there were written to Google
itself, as recommendations and vouchers of our work. First of all,
there is this letter from Célio Turino[1], idealizer of 'pontos de cultura',
a Brazilian federal program that reaches 8,4 million people (5% of Brazilian
population). It is a formal gift from him to LabMacambira and a homage to
Cleodon Silva (1949 - 2011), who inspired LabMacambira.sf.net.
The is also a formal document from the National Commission of the almost 4000
pontos which tells a little bit more about LabMacambira.sf.net's importance
for Cultura Viva[2]. The third letter came Ethymos, a partner enterprise
(LabMacambira.sf.net is not an enterprise) that joins LabMacambira.sf.net
in a direct democracy and free medias protagonist network in Brazil.
The fourth letter came from Puraqué, a collective based in Santarém,
in the Amazonian region [4]. Worth noticing that both Amazonian Free Software
Forum (FASOL) and Amazonian Forum of Digital Culture are in the third edition,
and the text might suggest otherwise.

== AA (client) ==
[[Imagem:Aa-macaco.png|right|bottom|alt=AA Console Client]]

[[AA]] is a social system for coordinating
distributed teamwork where each participant stays logged for at least 2 hours a day,
publicly microblogging
their development activities related to assigned tickets (self-assigned or team-assigned). At the end of each
daly session, a video log is recorded and [http://vimeo.com/channels/labmacambira uploaded to a public video channel],
the text log is also [http://hera.ethymos.com.br:1080/paainel/casca/ published on the Web] and is
peer-validated for quality. The AA system and its underlying software
engineering methodology enables self-funding for distributed collectives of
developers working on FLOSS projects.

'''Objective:''' AA is a distributed system following a client-server
architecture. Each AA client is a Python application in textual or GTK+ form that communicates
with the AA server, the web instance. Through the client each developer can send
messages and log his activities. Currently, AA client is a simple program
written to run in Linux. Being a software that aims to be used by everyone
it would be important to be multiplatform (perhaps as a web client) and to have
additional functionalities such as better Trac and Git log integration, RSS/Google+
developer feeds, and automatic videolog watermarking. A student working on AA could
work on these features for the program.

[[Imagem:Aapp2.png|right|bottom|alt=AA GTK2 Frontend]]

'''Suggested Roadmap:''' 1) Understand the AA architecture; 2) Use AA in its
current form to understand, as a developer working in a collaborative group,
what features are most needed. These features could be implemented during the
summer or documented for a future developers; 3) Research about how to make AA
multiplatform - we are planning to make a Web client; 4) Implement the features
on the TODO of the project and some of the features listed by yourself if
possible. 5) write a paper about the AA methodology and experiences with the
implemented system.

== pAAinel (AA server) ==
[[Imagem:Aa2.png|right|bottom|alt=AA]]

AA is a distributed system for coordinating decentralized teamwork, as described above. We need to develop the server side of AA, which already includes an aggregator of logs, and a master aggregator of all the team information in a dashboard which is similar to iGoogle: [http://hera.ethymos.com.br:1080/paainel/casca/ pAAinel]. Currently, [http://hera.ethymos.com.br:1080/paainel/casca/ pAAinel] merely displays information about logs registered by the AA server, together with complementary information, like a recent irc log, tickets and last screencasts and code commits.

'''Objective:''' We desire to rewrite the AA microblog server (actually written in PHP) as a module inside pAAinel, a Django application.

'''Suggested Roadmap:''' 1) Understand the current AA architecture; 2) Read both pAAinel (made in Django) and AA server (in PHP) code and associated documentation, planning how to rewrite AA server as a module inside pAAinel; 3) To develop and test the new pAAinel together with members of LabMacambira; 4) Continuouslly document the process.

== [[AirHackTable]] ==
[[Imagem:Aht.png|right|bottom|alt=AHT]]

The [[AirHackTable]] is an art project - an interactive music instrument based on advanced computer vision algorithms that track flying origamis, associating their trajectories, color, and shape to different musical properties. The recycled coolers inside a cardboard table (itself an origami) generates a layer of air on top of which colored origamis float around and make track patterns depending on their geometry. A set of webcams on top then captures those patterns through our own color detection and 3D reconstruction algorithms, and then generate and modulate sounds based on the trajectory, color, and shape of the origamis. Many are the technological spinoffs of this project, most of which were accepted officially into well-established software such as the [[Pd]]/Gem real time multimedia programming system and [[Scilab]].

'''Objective:''' The [[AHT]] project is an opportunity to develop and spread cutting-edge technology in a playful manner, which may seem otherwise too hard/unapproachable.
We plan to improve geometric recognition to be used for generating sounds for modulating voices that are in agreement with the geometry of the origami. The goal, then, is to implement algorithms for 3D edge/curve reconstuction from the mentor's research, in order to recover the origami's edges in 3D, thus recovering the true geometry of the origami. Other techniques such as 2D recognition of origami silhouettes should also be developed. This playful project is expected to generate technological spinoffs which will be incorporated into other well-established FLOSS projects such as [[Pd]], [[Scilab]], [[OpenCV]], and [http://vxl.sf.net VXL]. Some of the Google projects that can benefit from the underlying machine vision technology include Google Streetview, Google Book scanning, Google Image Search, and Youtube.

'''Suggested Roadmap:''' 1) compile and run the current system after downloading the large set of repositories and watching our screencasts; 2) brush up on the background: [[Pd]], [[C++]],
and Computer Vision, by talking to the mentors and watching our screencasts; 3) get the 3D reconstruction system up and running isolatedly 4) optimize the system to run in real time
5) incorporate the 3D reconstruction system into the [[AHT]] system; 6) write up documentation and papers on the core technologies.

== [[SIP]] + [[Scilab]] ==

[[Imagem:SIP_whitebg.png|right|bottom|alt=SIP toolbox]]
[[Imagem:Leptonica.jpg|right|bottom|alt=Leptonica Image Processing Library from Google]]

[http://siptoolbox.sf.net SIP] stands for [[Scilab]] Image Processing toolbox. [[SIP]] performs imaging tasks such
as filtering, blurring, edge detection, thresholding, histogram manipulation,
segmentation, mathematical morphology, color image processing, etc. It leverages
the extremely simple [[Scilab]] programming environment for prototyping complex computer
vision solutions.

'''Objective:''' First, to add functionality to the Google FLOSS project
[http://www.leptonica.com Leptonica] and interface most of this C library with Scilab.
Second, to throroughly document this library. Google projects that will most
benefit from this effort include Google Book search and Google Image Search.

'''Suggested Roadmap:''' 1) Run leptonica and SIP; 2) make a contribution to
Leptonica (at least a simple bugfix), which will help the student get started;
3) write the necessary C infrastructure to interface Leptonica
image structures with Scilab matrices
4) interface a Leptonica functionality with Scilab and document it thoroghly
5) repeat 4, prioritizing functions that can only be found in Leptonica.

== [[Scilab]] Interactive Visualization ==

[[Imagem:Scilab_logo.gif|200px|right|bottom|alt=Scilab]]

[[Scilab]] is a free rapid prototyping environment for numerical algorithm
development, similar to Octave, Matlab and (to some extent) Python. A powerful
interactive GUI is one of the main features that makes Scilab stand out from
Python and Octave in their current form. This is a central feature of scilab,
specially for large-scale data mining; the capability of interactively
exploring visual data to/from the scilab language is a fundamental part of
the process of prototyping a solution to a given problem.

'''Objective:''' This project aims to improve interactive data exploration and
editing features of Scilab graphics. In other words, the aim is to make plots
more interactive with data (clicking + deleting a curve, clicking + obtaining
data from a curve, etc). Primary objectives include: to improve tooltip
functionality, to improve editing capabilities, and to improve selection of
plots and inspection of values into a scilab varialble, both in 2D and 3D. This
basically means treating the scilab graphic window as a vector graphics, through
an editing interface, and then being able to get the data back in scilab. Other
objectives include the use of OpenGL for speeding up the speed of (vector)
graphics rendering in general, but always focusing on interactive features
(dragging points from a plot curve and obtaining the corresponding data, etc)

'''Suggested Roadmap:''' 1) Compile scilab from source and understand the
graphics branch from Git; 2) See what has already been done, by carrying out
minor changes in the code and contributing bugfixes as a starter project
3) Code the visual selection of individual points and curves and 3D surfaces, and outputting curve properties into a
scilab variable.
4) Improve the inspection of individual curve/surface elements/points with a tooltip
5) Code the deletion of isolated points and curves from a plot
6) Code point and curve editing functionality: click and drag a point will
change its (x,y) data. Similar for curves and surfaces, but dragging each
individual sample points independently, or even Bezier-style functionality could be
added.

== [[Scilab]] Fast and Flexible Image (Raster) Display ==
[[Imagem:SIP-shot4.png|250px|right|bottom|alt=Scilab]]

[[Scilab]] is a free rapid prototyping environment for numerical algorithm
development, similar to Octave, Matlab and (to some extent) Python. A powerful
interactive GUI for displaying raster data (matrices, images, marked pixels,
etc) would be one of the main features that makes Scilab stand out from Python and
Octave in their current form. Interactive graphics is a central feature of
scilab, specially for developing new image processing algorithms; the capability
of interactively exploring raster visual data to/from the Scilab language is a
fundamental part of the process of prototyping and debugging a new algorithmic
solution to a given image analysis problem.

'''Objective:''' This project aims to improve interactive '''raster''' data exploration and
editing features of Scilab graphics. In other words, the aim is to make image
display more interactive with data (clicking + modifying a pixel, clicking + obtaining
associated data from a pixel, etc). Primary objectives include: to improve tooltip
functionality, to improve display capabilities, and to improve selection of
pixels and inspection of their values and associated data into a scilab
varialble, both in 2D and 3D. This basically means treating the scilab graphic
window as a buffer from a raster graphics editor (such as GIMP), through an editing interface, and then being able
to get the data back in scilab. Other objectives include the use of OpenGL for
speeding up (raster) graphics rendering in general, but always
focusing on interactive features and flexible displays. Each pixel should be
efficiently displayed, not only with traditional OpenGL functionality such as pan and zooming,
but most importantly with the ability of having custom ''markers'' to overlay on
the pixels in a fast way. Many image processing algorithms require pixels to be
marked in order to be debugged or animated.

'''Suggested Roadmap:''' 1) Compile scilab from source and understand the
graphics branch from Git; 2) See what has already been done, by carrying out
minor changes in the code and contributing bugfixes as a starter project
3) Code the visual selection of individual pixels, and outputting pixel
properties (which can be a complex data structure) into a scilab variable.
4) Optimize the speed of the image display
4) Improve the inspection of individual pixels with a tooltip
5) Code the display of individual pixels with custom markers, in a fast way
using OpenGL.
6) Finalize a complete fast and flexible display for image/raster data in
Scilab. Incorporate it into a full-fledged fast <tt>imshow</tt> function in SIP,
the Scilab Image Processing toolbox.

[[Imagem:Agora2.png|right|bottom|alt=Ágora Delibera]]

Envisioning direct democracy, this simple deliberation algorithm has been used in different forms by collectives and in software. From a PHP or Django ''hacksware'' to state of art direct democracy as is Delibera, from [http://www.ethymos.com.br Ethymos], a LabMacambira.sf.net partner and co-worker. In fact it is in use by ONU in almost 90 countries for 'habitation rights'. There is also an interesting LabMacambira.sf.net REST version already being tested and an official release o Delibera, from Ethymos partnerts, envisioning this year's election for mayors and councillors. There is a nacional alliance dedicated to direct democracy
going on and writing the [http://pontaopad.me/cartademocraciadireta Open Democracy Letter] which encourage and support
the use of Agora Delibera's mechanisms and codes for representative mandates and public sphere.

'''Objectives:''' Enhance REST deliberation tool to acceptable standards of use for elected representatives. Explore
Ágora Communs; ''hacksware'' to implement and test deliberation modes. With permission to viewing and posting. Test and
implement email, SMS, etc interfaces to Ethymos' Delibera.

'''Suggested Roadmap:''' Study ágora delibera's [https://github.com/teiacasadecriacao/agora-communs/wiki simple mechanism for deliberation].
Get in touch with ongoing [http://wiki.nosdigitais.teia.org.br/GT-Web#.C3.81gora_Communs_.28atual_.C3.81gora_Delibera.29 team and code].
With current development team, choose core features to better apps. Work close with team in irc channel #labmacambira and
maybe try working with [[AA]] as methodology and documentation.

== reacPad ==

We are planning to create a plugin to [http://etherpad.org EtherPad] that makes possible to run JavaScript (and maybe other languages) inside of EtherPads and to be programmable collaborative the same way EtherPad already does for common text.

Important to say that EtherPad is an interesting tool to civil society. With pads we are creating logs for reunions and documents of many kinds (take a look at our page [[Epads]]). It is interesting to take a look at [http://worrydream.com/Tangle/ Bret Victor works on "reactive documents"]. It is a kind of documents we are interested to implement using pads.

'''Objective:''': Create a plugin to [http://beta.etherpad.org EtherPad Lite] (the [[http://nodejs.org node.js]] port of EtherPad) to make possible to embed JavaScript scripts inside a pad.

'''Suggested Roadmap:''' 1) Study the EtherPad Lite architecture; 2) Be part of EtherPad Lite maillist and IRC channel and review the status of plugins development. As we know, today there is not a plugin system for EtherPad Lite, so there will be a task to create a first prototype of a plugin to the system; 3) Develop the plugin inside the plugin system to embed the scripts; 4)

'''Repos:''': The EtherPad Lite GIT repos is a good starting point https://github.com/Pita/etherpad-lite

ABeatTracker is a music software for real time execution of specialized macros
that play rythmic patterns with samples. Its internal module ABeatDetector (ABD),
is a rythmic analiser oriented towards indicating periodicities (symmetryc overal duration cells) in a
tapped in rythm. Its porpuse is to indicate musical cells and successions
that can be used immediatelly in ABT, making it possible to really
play live indicating structures that makes sense and develops what your
partner or base is playing.

'''Objectives:''' open for student proposal. Would be really good if ABD and ABT where finaly conected and
ABT could then use ABD's rythmic analysis. Also, ABT could have a Vi or Emacs interface
for live performance with approppriate shortcuts and abbreviations for musical code
execussion.

'''Roadmap:''' while open for student creativity, musical execution of the code
will reveal hacks that creates interesting musical structures. In a way or another,
it would be good so recover or redesign ABD's code (it has been schatched or broken) and
its communication with ABT.

Also, creating 'presets' and abreviations in Vi or Emacs
will provide lots of sound banks and 'musical set' examples. This ideally leads to further
development of livecoding interfaces in Emacs and Vi.

'''Languages:''' Python and ChucK comunicating via OSC mainly, vi and Emacs scripting too

[http://toplap.org Livecoding] is an alternative way to compose and interpret music in real-time. The performer/composer plays on a laptop and shows your screen to the public, making them part of the performance and even understanding what the musician is really doing to generate that weird sounds. Livecoders commonly use general domain languages or creates their own computer music languages. Vivace is an attempt to create a Livecoding language that runs in the Open Web using the new [https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html Web Audio] and [https://wiki.mozilla.org/Audio_Data_API Audio Data] APIs.

'''Objective:''' Continue to add features to Vivace, a Livecoding language that runs on Web browsers.

'''Suggested Roadmap:''' 1) Understand the architecture of Vivace and [http://github.com/oampo/Audiolet Audiolet] (the awesome JavaScript Audio lib created by Joe Turner); 2) Understand features specified at TODO and present at other languages like [http://www.ixi-audio.net/content/software.html ixi lang] and ABT/ABD; 3) Implement the features; 4) Screencast performances using Vivace, maybe public ones.

IRC bots are social technology by nature. Autonomous software agents that can talk directly with people are powerful tools to understand their needs. We visualize IRC as a direct channel to communicate with people. Macambot, Lalenia and coBots are Supybots, Python IRC robots we want to continuously develop as agents that can collect software features proposed by the people and interact with them.

'''Objective:''' Continue the deveopment of the Supybots Macambot, Lalenia and coBots.

'''Suggested Roadmap:''' 1) Understand Supybot and its plugins; 2) Develop a test plugin to interact with people collecting their suggestions as software features; 3) Study Python NLTK (Natural Language Toolkit); 4) Improve the plugin with natural language processing, to talk with people "as a human"; 5) Create a Trac plugin to add bug and features entries based on the IRC bots data base of conversation with people that use #labmacambira at irc.freenode.net and/or other channels and IRC servers

== Permanent Conference ==
[[Imagem:Conf-perm2.png|right|bottom|alt=Per]]

Every year in Brazil we have the Conference for Defense of Children Rights along all the country. This
are ephemeral reunions, that can benefit alot from a good platform for permanent discussion.

What happens when the conference end? Where the ideas discussed at the conference goes and whats happening about it? Permanent Conference is a Web application to collect knowledge generated on these conferences and to make sure they will be available to all the people.

'''Objective:''' Continue the implementation of the Django application Permanent Conference

'''Suggested Roadmap:''' 1) Read the code already written for the application. It was written in Django, so it is good to have a minor knowledge about that; 2) Understand the [ missed features] and bugs around. Trac is a good point to start; 3) Implement the features; 4) Test with people from Pontos de Cultura from Brazil.

== SOS ==
[[Imagem:Sos2.png|right|bottom|alt=SOS]]

"Saúde Olha Sabedoria" (or Health, Look! Knowledge) is a Web application to collect popular tips around human health. People can also learn how to use popular knowledge to cure their deceases. We believe that softwares like SOS are an interesting way to preserve the culture of a nation and spread it to the others.

'''Objective:''' Fix some bugs on SOS and extend the concept to other areas, creating a knowledge base around popular culture

'''Suggested Roadmap:''' 1) Understand SOS architecture. It was written in Python using Django, so it is important to have a minor knowledge of these technologies; 2) Look at our Trac for bugs related in SOS and fix them; 3) Look for new features. The Trac is again a good start; 4) Extend the SOS to allow the insertion of other kinds of knowledge, not just related with health; 4) Test the platform with people of Pontos de Cultura and collect their feedback

== História ==

Macambira foi um pseudônimo usado por [http://www.youtube.com/watch?v=D7Lz82m2m2I Cleodon Silva], grande vetor da cultura livre, falecido em São Paulo, no dia 7 de junho de 2011 aos 61 anos.

Renato Fabbri e Daniel Marostegan conceberam o grupo juntando-se a Vilson Vieira e Ricardo Fabbri, para trabalho de desenvolvimento de tecnologias de software livre, inicialmente nas áreas:

*Audiovisual
*Web

=== Timeline ===

Junho 2011: concepcao, organizacao, chamada para recrutamento, socializacao

Julho 2011: entrevistas, tour da teia e do lab para interessados, treinamento intensivo em projetos de software livre, atividade intensiva em geral para fazer o projeto rolar.

Agosto 2011: primeiro mês de AAacambira.

== Iniciando no Lab Macambira ==

*Manual para os que iniciarem no time: [[Manual do Novato]]

=== Usando o AA ===

Algumas recomendações de como utilizar bem o AA.

POST:

*15 min +- 5m, ou seja, temos 5 minutos de tolerância. Fora desta margem, o log é perdido.
**pode estourar até 20% dos logs em um mes sem abono de bônus
**entre 20 e 30% perde 150 conto
**entre 30 e 40% perde 300 conto
**entre 40 e 50% perde 450 conto e fica passíel de remoção
*Posts extras ao bel prazer

SESSÕES E REPOSIÇÕES

*pode perder e repor ate 3 dias sem abono de bônus
*cada dia além do terceiro dia perde 50 conto
*perdeu 7 dias ou mais, mesmo repondo, fica passível de remoção
*não pode repor mais de uma sessão (2h) em um dia

SESSÕES PERDIDAS

*cada dia perdido e sem repor, perde 100
*3 dias ou mais sem repor, fica passível de remoção do lab

VALIDAÇÕES DOS LOGS

*Cada dia chega um log para cada um validar (atribuição randômica)
*Quem valida fica anônimo (não para a gerência)
*Pontos (uma frase para cada):
**Fortes
**Fracos
*Classificação em: Imprestável, ruim, regular, bom, excelente

TASK LIST

*Cada GT tem seu task list com prioridades e deadlines (task list externo ao AA numa primeira versao, p.ex. sourceforge),

com tasks alocadas a cada macambira

*Cada Macabira associa-se a um e somente um GT primário no qual ficará logado pelo AA.
*A princípio cada um tem autonomia para escolher seu GT primário
*À gerência, cabe realocar Macambiras em caso de necessidade

ATIVIDADE:

*Desligar celular
*Ficar em lugar não movimentado
*Concentrado
*Baseado em:
**Meritocracia
**Auto-regulagem Social
*Screencast diário de 2-10 min. (sem ele o log fica inválido)

ADENOS:

*Em caso de rendimento claramente insatisfatório, pode-se aumentar as horas para 3h diárias
*Constatada falcatrua, a pessoa automaticamente perde os benefícios financeiros e rola um queima filme forte.

IRC

2011-12-08T20:55:13Z

Marcosm:

Internet Relay Chat ou IRC e' a maneira de bate-papo em grupo mais tradicional da Internet e da comunidade Hacker. A sala de bate-papos do Lab Macambira e' a:
#labmacambira na rede freenode

O log do canal pode ser acessado em:
http://hera.ethymos.com.br:1080/~macambot/labmacambira_lalenia3.txt

== Clientes ==
O IRSSI e' atualmente o cliente mais aclamado na comunidade Hacker. Muitas pessoas tambem usam o XChat.

== Automatizando ==

E' cultura hacker estar sempre logado nas salas de bate papo de seu interesse no IRC, mesmo sem estar batendo papo a todo instante.

=== Startup no Ubuntu ===

Para iniciar o IRSSI de forma automatica no Ubuntu, va' em Startup Aplications (no Unity, clique no logotipo do Ubuntu na barra de tarefas ou aperte o botao do ruindows, e busque por startup applications). Em seguida clique em "Add", Name IRSSI, command:
/usr/bin/xterm irssi

=== Entrando nas salas automaticamente ===

==== IRSSI ====
As configurações do irssi ficam em .irssi/config
O Irssi pode realizar boa parte dessas configurações automaticamente através da conexão no servidor e do /save

===== Conectando no servidor =====
Dentro do arquivo de configurações, no array "servers" adicione:

{
address = "irc.freenode.net";
chatnet = "freenode";
port = "7000";
use_ssl = "yes";
ssl_verify = "no";
autoconnect = "yes";
},

===== Autenticando Usuário =====
Se seu user for cadastrado na freenode, adicione isso no array chatnets pra logar automaticamente:

freenode = {
type = "IRC";
autosendcmd = "/^nick [seu nick];/^msg nickserv identify [sua senha];wait 2000";
};

===== Entrando no canal =====
Adicionar no array channels o #labmacambira:

{ name = "#labmacambira"; chatnet = "freenode"; autojoin = "yes"; },

=== Conectando automaticamente com XChat ao iniciar o Ubuntu ===

Antes de tudo, instale o XChat:

sudo aptitude install xchat

Depois vá no menu '''XChat''' e depois em '''Lista de redes...'''.

Procure a rede '''Freenode''' na caixa de seleção '''Redes''' e selecione-a. Ao lado, clique em '''Editar...'''. Em '''Canais favoritos''' coloque os canais que quer conectar, separados por vírgula. Na mesma janela, há a opção '''Ligar automaticamente ao início'''. É só habilitá-la e pronto.

Para abrir o XChat assim que iniciar a sessão do Ubuntu:

Execute o '''gnome-session-properties''', clique em '''Adicionar'''. Depois complete o campo '''Nome''' com '''XChat''' e o comando '''xchat'''. Feito.

== Comandos Basicos ==
=== IRSSI ===
Para mudar o canal, use Ctrl-N e Ctrl-P.

Para entrar num canal, use, por exemplo,
/join #labmacambira

Para olhar o log de um canal, simplesmente use Page-Up e Page-Down.

== Outros Canais Uteis ==

#gnu, #fsf, #ubuntu, #ubuntu-br, #linux

Instalando CPC no DreamHost

2011-08-23T19:03:00Z

Marcosm:

As instruções para fazer o Django funcionar no DreamHost estão na wiki: [http://wiki.dreamhost.com/Django]

Depois é preciso fazer algumas alterações no script do Passenger, no caso adicionar a seguinte linha para colocar a aplicação no path:

<pre>sys.path.append(os.path.join(os.getcwd(), 'cpc'))</pre>

Vale observar que o script django-setup.py deve ser executado dentro da pasta onde foi criada a pasta 'public'.

Passos para poder fazer push também:

Executar o comando: ssh-keygen -t dsa
Ps.: Não consegui fazer funcionar sem senha, então basta usar AA123

Depois abra o arquivo id_dsa.pub dentro da pasta ~/.ssh/

Ai é só copiar esse texto (chamado chave ssh) que tem lá dentro e me enviar(Lucas) pra liberar acesso ao projeto no Gitorious
(ps.: caso você use o root + seu usuário normal alternadamente para o git, faça o processo com os dois usuários e envie as 2 chaves)

Depois só dar o git clone, git push, git pull, ... No endereço GIT.
git@gitorious.org:macambira_aa/macambira_aa.git

== Reuniões ==

=== 18-Jul-2011 ===

Horário: 14:00hs

Participantes: Alexandre, Lucas, Marcos Mendonça, Nivaldo, Renato.

''' Ideias: '''

* Definir campos

* Twitter ( 100% aprovação )

* IRC
** Canal AA com ''bot'' para registrar de forma limpa

* Pensar em validação do parceiro

* Escolher o aviso sonoro
** Opção: Falar o nome/nick da pessoa

* Janela de notificação semi-transparente (estilo padrão do Ubuntu)

''' Esqueleto mínimo: '''

* Banco de dados:
** Usuário (cadastro)
** Mensagens
** Configurações (intervalos de notificações dos usuários, manter hisótico de alteração das durações por data e hora)

* A princípio desenvolver nos dois
** Browser -> Portabilidade
** Python -> Funcionalidade

* Notificações
** A cada 30 minutos. Repete a cada 30 segundos até que receba a mensagem. Pode mudar segundo a Tabela de configurações.

* Mensagem
** A princípio, no máximo 100 caracteres

[[Category:Lab Macambira]]

== Concepção para reunião de quarta-feira ==
[[Usuário:Rfabbri|Rfabbri]] 02h04min de 27 de Julho de 2011 (UTC)

<pre>
POST:
* 15 min +- 5m, ou seja, temos 5 minutos de tolerância. Fora desta margem, o log é perdido.
** pode estourar até 20% dos logs em um mes sem abono de bônus
** entre 20 e 30% perde 150 conto
** entre 30 e 40% perde 300 conto
** entre 40 e 50% perde 450 conto e fica passíel de remoção
* Posts extras ao bel prazer

SESSÕES E REPOSIÇÕES
-> pode perder e repor at 3 dias sem abono de bonus
-> cada dia além do terceiro dia perde 50 conto
-> perdeu 7 dias ou mais, mesmo repondo, fica passível de remoção
-> não pode repor mais de uma sessão (2h) em um dia

SESSÕES PERDIDAS
-> cada dia perdido e sem repor, perde 100
-> 3 dias ou mais sem repor, fica passível de remoção do lab

VALIDAÇÕES DOS LOGS
* Cada dia chega um log para cada um validar (atribuição randômica)
* Quem valida fica anônimo (não para a gerência)
* Pontos (uma frase para cada):
** Fortes
** Fracos
* Classificação em: Imprestável, ruim, regular, bom, excelente

TASK LIST
* Cada gt tem seu task list com prioridades e deadlines (task list externo ao AA numa primeira versao, p.ex. sourceforge),
com tasks alocadas a cada macambira
* Cada Macabira associa-se a um e somente um gt primário no qual ficará logado pelo AA.
* A princípio cada um tem autonomia para escolher seu gt primário
* À gerência, cabe realocar Macambiras em caso de necessidade

SISTEMÁTICA:
* Cada sessão gera um log, que possui
** os posts
** o identificador de usuário
* Feed em tempo real (no caso de falta de conexão com a web, fica arquivo txt)

INTERFACE WEB:
* Mostra quando falhou o timeslot do Macambira
* Mostra o dia em que falhou
* Mostra reposição
* Mostra tempo extra
* Mostra por seleção de usuário

ATIVIDADE:
* Desliga celular
* Fica em lugar não movimentado
* Concentrado
* Baseado em:
** Meritocracia
** Auto-regulagem Social
* Screencast diário de 2-10 min. (sem ele o log fica inválido)

ADENO:
* Em caso de rendimento claramente insatisfatório, pode-se aumentar as horas para 3h diárias</pre>

== TODO (28/07/2011) ==

* Terminar relógio (AADaemon) '''FEITO'''
* Enviar todo o log em uma única requisição HTTP (AAHTTPSender) '''FEITO'''
* Refinar AA Web
** Campo vermelho para slots perdidos '''FEITO'''
** Datas '''FEITO'''
* Incluir bonificação/penalização
* Validar log AA Web '''FEITO'''
* Configuração '''FEITO'''
