== 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 ====

== 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.

=== Wearable Health Monitor ===

[[Imagem:Beat.jpg|400px|right|bottom|alt=Monitor]]

Dwells the use of sensors to register life signals and build an open and non-invasive public database. A wearable monitor to track vital information (like heart beat, body temperature and pulse) and make it public to anyone on the Web. Imagine have a database of our clinic state in some easy way to measure. This can be helpful in diagnostics of diseases. Or maybe we can find a way of analyze these informations in order to correlate different people routines in the same country.

'''Objective:''' The main concept is to demystify how we can measure your vital information. Opening this information to everyone.

'''Suggested Roadmap:'''

1) Study which are the body information that we can track

2) Find ways to create or use sensors to track these body informations

3) Write tutorials

== Games ==
[[Imagem:Playn-logo.png|145px|right|bottom|alt=PlayN -- Cross Platform Game Framework originated at Google]]
[[Imagem:Logo-gwt.png|right|bottom|alt=GWT -- Google Web Toolkit]]

Cross-platform open-source games using PlayN and Google Web Toolkit technology, working closely with cartoonists and hackers.
The intent of this in not only to work to produce funny and interesting games, but also to develop the PlayN framework engine itself
in the process. Even though PlayN is itself open source, it currently lacks open source games and professionally-looking demos. Through these projects you will help develop such awesome technology that was born inside the google GWT team and help it blossom. In addition, these projects will give you the skills experience to build any complex interactive application in a single uniform Java base that works both on the desktop and on mobile platforms, both natively or through the Web or a Java VM. The technology that makes this possible is derived from GWT and we are confident from our previous market and community surveys that it is important to get experience with it and develop it further in an open manner.

Throughout Google Summer of Code we will be constantly asking the question: is it worth developing a professional-grade game in PlayN style Java and tweaking the backends (HTML5, iOS, etc) to maintain a better code base, or would we rather just write the game in HTML5/Javascript directly?

=== [[Pet]] ===

Pet is a game about having this virtual being or pet (in our specific case, a bunny) which you
take care since its infancy. Our twist to this is in a very comic teen/young adult direction, working with cartoonists from [http://www.pulapirata.com PulaPirata.com]
for the art and concepts. Basically it is a living cartoon bunny called Pingo, where the actions you take during its lifetime
will make for different comic results, such as very dorky or very rebel. In a deeper way, this analyzes and satirizes the way we grow up in
our current society. In a broader sense, the technology used here will be leveraged to build a general cross-platform engine for virtual pet games based on PlayN.
These kinds of games fit perfectly with mobile devices and casual web games. Moreover, this strikes a good complexity level to get us started
with serious PlayN programming - it is not very simple, as it can easily go to RPG directions, and it is not very complex since we are using a retro style of 2D or pseudo-2D comic art.

'''Objective:''' To build a virtual pet PlayN engine which runs on the Web, android and iOS, making a separate release. Make it work with our proposed art and script and release the Pet game.

'''Suggested Roadmap:''' See our detailed roadmap in [[Pet]]

=== [[SimBar]] ===

Build and run a bar-like business and attract eccentric figures to your circle of dear friends.
This isometric game is similar to the classic SimCity, but with more social tendencies and
geared toward the teenage/young adult public. One starts with an establishment which can
be a very simple bar with comic characteristics depending on its geographic and cultural context.
The success of the business can go in many directions during the game, from a straight cafe or restaurant
to a full-fledged nightclub. Some of the characters who go to experience these establishments could be actual
avatars from real people, who could enjoy the quirky style service and culture of each place and even
recommend them.
'''This game would yield a full-fledged open-source isometric and social engine for PlayN,
which is currently lacking.'''

'''Objective:''' To build a business establishment simulator PlayN engine which runs on the Web, android and iOS, making a separate release. Make it work with our proposed art and script and release the SimBar game.

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.

=== [[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.

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;

=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.

The mentorings named below for each idea corresponds to individual affinities
for the trend. In practice, all mentors will be mentoring together. See also the [[SummerOfCode2014#Mentors| Mentors]] section.

== 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.

[[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;

[[Imagem:Beat.jpg|400px|right|bottom|alt=Monitor]]

Dwells the use of sensors to register life signals and build an open and non-invasive public database. A wearable monitor to track vital information (like heart beat, body temperature and pulse) and make it public to anyone on the Web. Imagine have a database of our clinic state in some easy way to measure. This can be helpful in diagnostics of diseases. Or maybe we can find a way of analyze these informations in order to correlate different people routines in the same country.

'''Objective:''' The main concept is to demystify how we can measure your vital information. Opening this information to everyone.

== Games ==
[[Imagem:Playn-logo.png|145px|right|bottom|alt=PlayN -- Cross Platform Game Framework originated at Google]]
[[Imagem:Logo-gwt.png|right|bottom|alt=GWT -- Google Web Toolkit]]

Cross-platform open-source games using PlayN and Google Web Toolkit technology, working closely with cartoonists and hackers.
The intent of this in not only to work to produce funny and interesting games, but also to develop the PlayN framework engine itself
in the process. Even though PlayN is itself open source, it currently lacks open source games and professionally-looking demos. Through these projects you will help develop such awesome technology that was born inside the google GWT team and help it blossom. In addition, these projects will give you the skills experience to build any complex interactive application in a single uniform Java base that works both on the desktop and on mobile platforms, both natively or through the Web or a Java VM. The technology that makes this possible is derived from GWT and we are confident from our previous market and community surveys that it is important to get experience with it and develop it further in an open manner.

Throughout Google Summer of Code we will be constantly asking the question: is it worth developing a professional-grade game in PlayN style Java and tweaking the backends (HTML5, iOS, etc) to maintain a better code base, or would we rather just write the game in HTML5/Javascript directly?

=== [[Pet]] ===

Pet is a game about having this virtual being or pet (in our specific case, a bunny) which you
take care since its infancy. Our twist to this is in a very comic teen/young adult direction, working with cartoonists from [http://www.pulapirata.com PulaPirata.com]
for the art and concepts. Basically it is a living cartoon bunny called Pingo, where the actions you take during its lifetime
will make for different comic results, such as very dorky or very rebel. In a deeper way, this analyzes and satirizes the way we grow up in
our current society. In a broader sense, the technology used here will be leveraged to build a general cross-platform engine for virtual pet games based on PlayN.
These kinds of games fit perfectly with mobile devices and casual web games. Moreover, this strikes a good complexity level to get us started
with serious PlayN programming - it is not very simple, as it can easily go to RPG directions, and it is not very complex since we are using a retro style of 2D or pseudo-2D comic art.

'''Objective:''' To build a virtual pet PlayN engine which runs on the Web, android and iOS, making a separate release. Make it work with our proposed art and script and release the Pet game.

'''Suggested Roadmap:''' See our detailed roadmap in [[Pet]]

=== [[SimBar]] ===

Build and run a bar-like business and attract eccentric figures to your circle of dear friends.
This isometric game is similar to the classic SimCity, but with more social tendencies and
geared toward the teenage/young adult public. One starts with an establishment which can
be a very simple bar with comic characteristics depending on its geographic and cultural context.
The success of the business can go in many directions during the game, from a straight cafe or restaurant
to a full-fledged nightclub. Some of the characters who go to experience these establishments could be actual
avatars from real people, who could enjoy the quirky style service and culture of each place and even
recommend them.
'''This game would yield a full-fledged open-source isometric and social engine for PlayN,
which is currently lacking.'''

'''Objective:''' To build a business establishment simulator PlayN engine which runs on the Web, android and iOS, making a separate release. Make it work with our proposed art and script and release the SimBar game.

=== [[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.

[[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;

=== [[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,

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;

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.

=== 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.

=== Wearable Health Monitor ===

[[Imagem:Beat.jpg|400px|right|bottom|alt=Monitor]]

Dwells the use of sensors to register life signals and build an open and non-invasive public database. A wearable monitor to track vital information (like heart beat, body temperature and pulse) and make it public to anyone on the Web. Imagine have a database of our clinic state in some easy way to measure. This can be helpful in diagnostics of diseases. Or maybe we can find a way of analyze these informations in order to correlate different people routines in the same country.

'''Objective:''' The main concept is to demystify how we can measure your vital information. Opening this information to everyone.

'''Suggested Roadmap:'''

1) Study which are the body information that we can track

2) Find ways to create or use sensors to track these body informations

3) Write tutorials

== Games ==
[[Imagem:Playn-logo.png|145px|right|bottom|alt=PlayN -- Cross Platform Game Framework originated at Google]]
[[Imagem:Logo-gwt.png|right|bottom|alt=GWT -- Google Web Toolkit]]

Cross-platform open-source games using PlayN and Google Web Toolkit technology, working closely with cartoonists and hackers.
The intent of this in not only to work to produce funny and interesting games, but also to develop the PlayN framework engine itself
in the process. Even though PlayN is itself open source, it currently lacks open source games and professionally-looking demos. Through these projects you will help develop such awesome technology that was born inside the google GWT team and help it blossom. In addition, these projects will give you the skills experience to build any complex interactive application in a single uniform Java base that works both on the desktop and on mobile platforms, both natively or through the Web or a Java VM. The technology that makes this possible is derived from GWT and we are confident from our previous market and community surveys that it is important to get experience with it and develop it further in an open manner.

Throughout Google Summer of Code we will be constantly asking the question: is it worth developing a professional-grade game in PlayN style Java and tweaking the backends (HTML5, iOS, etc) to maintain a better code base, or would we rather just write the game in HTML5/Javascript directly?

=== [[Pet]] ===

Pet is a game about having this virtual being or pet (in our specific case, a bunny) which you
take care since its infancy. Our twist to this is in a very comic teen/young adult direction, working with cartoonists from [http://www.pulapirata.com PulaPirata.com]
for the art and concepts. Basically it is a living cartoon bunny called Pingo, where the actions you take during its lifetime
will make for different comic results, such as very dorky or very rebel. In a deeper way, this analyzes and satirizes the way we grow up in
our current society. In a broader sense, the technology used here will be leveraged to build a general cross-platform engine for virtual pet games based on PlayN.
These kinds of games fit perfectly with mobile devices and casual web games. Moreover, this strikes a good complexity level to get us started
with serious PlayN programming - it is not very simple, as it can easily go to RPG directions, and it is not very complex since we are using a retro style of 2D or pseudo-2D comic art.

'''Objective:''' To build a virtual pet PlayN engine which runs on the Web, android and iOS, making a separate release. Make it work with our proposed art and script and release the Pet game.

'''Suggested Roadmap:''' See our detailed roadmap in [[Pet]]

=== [[SimBar]] ===

Build and run a bar-like business and attract eccentric figures to your circle of dear friends.
This isometric game is similar to the classic SimCity, but with more social tendencies and
geared toward the teenage/young adult public. One starts with an establishment which can
be a very simple bar with comic characteristics depending on its geographic and cultural context.
The success of the business can go in many directions during the game, from a straight cafe or restaurant
to a full-fledged nightclub. Some of the characters who go to experience these establishments could be actual
avatars from real people, who could enjoy the quirky style service and culture of each place and even
recommend them.
'''This game would yield a full-fledged open-source isometric and social engine for PlayN,
which is currently lacking.'''

'''Objective:''' To build a business establishment simulator PlayN engine which runs on the Web, android and iOS, making a separate release. Make it work with our proposed art and script and release the SimBar game.

[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";

=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;

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.

=== Wearable Health Monitor ===

[[Imagem:Beat.jpg|400px|right|bottom|alt=Monitor]]

Dwells the use of sensors to register life signals and build an open and non-invasive public database. A wearable monitor to track vital information (like heart beat, body temperature and pulse) and make it public to anyone on the Web. Imagine have a database of our clinic state in some easy way to measure. This can be helpful in diagnostics of diseases. Or maybe we can find a way of analyze these informations in order to correlate different people routines in the same country.

'''Objective:''' The main concept is to demystify how we can measure your vital information. Opening this information to everyone.

'''Suggested Roadmap:'''

1) Study which are the body information that we can track

2) Find ways to create or use sensors to track these body informations

3) Write tutorials

== Games ==
[[Imagem:Playn-logo.png|145px|right|bottom|alt=PlayN -- Cross Platform Game Framework originated at Google]]
[[Imagem:Logo-gwt.png|right|bottom|alt=GWT -- Google Web Toolkit]]

Cross-platform open-source games using PlayN and Google Web Toolkit technology, working closely with cartoonists and hackers.
The intent of this in not only to work to produce funny and interesting games, but also to develop the PlayN framework engine itself
in the process. Even though PlayN is itself open source, it currently lacks open source games and professionally-looking demos. Through these projects you will help develop such awesome technology that was born inside the google GWT team and help it blossom. In addition, these projects will give you the skills experience to build any complex interactive application in a single uniform Java base that works both on the desktop and on mobile platforms, both natively or through the Web or a Java VM. The technology that makes this possible is derived from GWT and we are confident from our previous market and community surveys that it is important to get experience with it and develop it further in an open manner.

Throughout Google Summer of Code we will be constantly asking the question: is it worth developing a professional-grade game in PlayN style Java and tweaking the backends (HTML5, iOS, etc) to maintain a better code base, or would we rather just write the game in HTML5/Javascript directly?

=== [[Pet]] ===

Pet is a game about having this virtual being or pet (in our specific case, a bunny) which you
take care since its infancy. Our twist to this is in a very comic teen/young adult direction, working with cartoonists from [http://www.pulapirata.com PulaPirata.com]
for the art and concepts. Basically it is a living cartoon bunny called Pingo, where the actions you take during its lifetime
will make for different comic results, such as very dorky or very rebel. In a deeper way, this analyzes and satirizes the way we grow up in
our current society. In a broader sense, the technology used here will be leveraged to build a general cross-platform engine for virtual pet games based on PlayN.
These kinds of games fit perfectly with mobile devices and casual web games. Moreover, this strikes a good complexity level to get us started
with serious PlayN programming - it is not very simple, as it can easily go to RPG directions, and it is not very complex since we are using a retro style of 2D or pseudo-2D comic art.

'''Objective:''' To build a virtual pet PlayN engine which runs on the Web, android and iOS, making a separate release. Make it work with our proposed art and script and release the Pet game.

'''Suggested Roadmap:''' See our detailed roadmap in [[Pet]]

=== [[SimBar]] ===

Build and run a bar-like business and attract eccentric figures to your circle of dear friends.
This isometric game is similar to the classic SimCity, but with more social tendencies and
geared toward the teenage/young adult public. One starts with an establishment which can
be a very simple bar with comic characteristics depending on its geographic and cultural context.
The success of the business can go in many directions during the game, from a straight cafe or restaurant
to a full-fledged nightclub. Some of the characters who go to experience these establishments could be actual
avatars from real people, who could enjoy the quirky style service and culture of each place and even
recommend them.
'''This game would yield a full-fledged open-source isometric and social engine for PlayN,
which is currently lacking.'''

'''Objective:''' To build a business establishment simulator PlayN engine which runs on the Web, android and iOS, making a separate release. Make it work with our proposed art and script and release the SimBar game.

'''Suggested Roadmap:''' Check out our design docs at [[SimBar]]

[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:'''

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.

=== [[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

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.

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.

(14:06:29) automata: minha formação é em ciência da computação, Udesc/SC

(14:06:47) lecasteloes: ótimo... e tua relação com a música?

(14:07:04) automata: vim para são carlos a convite do Renato Fabbri, bom amigo assim como glerm que nos apresentou

(14:07:30) automata: a música vem pela curiosidade, não tenho formação

(14:07:54) lecasteloes: mas, vc programa ou já programou algum algoritmo pra som/ música?

(14:07:56) automata: faço experimentações usando tecnologias, web, linguagens, livecoding...

(14:08:09) lecasteloes: ótimo!

(14:08:39) lecasteloes: o "Lalenia" é o Renato?

(14:08:46) lecasteloes: Fabri?

(14:10:47) glerm: eu trabalho com software e hardware livre ja fazem alguns anos

(14:10:54) glerm: com software livre fazem quase 10

(14:11:24) glerm: basicamente comecei a cada vez mais me envolver com a parte de programação quando iniciei a pesquisa com puredata

(14:11:41) lecasteloes: pra música ou outra aplicação?

(14:12:09) glerm: eu comecei a curiosidade com música, pois sempre tive bandas e projetos musicais

(14:12:29) glerm: depois que comecei a aprender me interessei tanto que fui estudar Ciência da Computação

(14:12:37) lecasteloes: e na graduação vc fez?

(14:12:40) glerm: isso

(14:12:50) lecasteloes: uhum...

(14:13:17) lecasteloes: Yago, estamos nos apresentando aqui... vc poderia dizer umas frases a respeito da sua atuação?

(14:15:34) yagofranco: Bem, estou me formando agora no bacharelado em música da UFJF. Tenho grande interesse na área de semiótica, composição algorítmica e audio-tecnologia em geral.

(14:16:15) glerm: só pra finalizar minha apresentação - trabalhei bastante na pesquisa com construção de instrumentos musicais pois dei bastante oficinas sobre isso (em SESCs, pontos de cultura, projetos artísticos), dentro do contexto de instrumentos D.I.Y. estas coisas. Tenho um software sampler desenvolvido em PD chamado navalha... http://navalha.devolts.org . Já fiz algumas coisas junto com Vilson e Renato também, com labmacambira e submidialogias entre outros trampos.

(16:35:52) automata: isso, esse vídeo comecei a ver ontem, viagem

(16:36:15) automata: glerm, o hybrid soltou a ideia de transformar esse curso CAC em um coursera

(16:37:59) automata: mesmo princípio do sinal analógico de tv será?

(16:41:25) glerm: tem que ver os detalhes do protocolo que ele ta usando

(16:41:30) glerm: o que é coursera?

yago, qual mesmo o comando para ver o código fonte em lisp?

Yago Franco 2:41 PM
command + shift + L

me 2:41 PM
valeu
hmm aqui mostrou o lisp listener yago

Yago Franco 2:42 PM
a perdão, confundi
mas o eu não me lembro
codigo

me 2:43 PM
ah, uma possibilidade é abrir o .omp
ele é basicamente um código lisp certo?
bem legal

glerm soares 2:44 PM

me 2:44 PM
nesse patch faltou OMAlea
não rolou glerm
vou ver depois

glerm soares 2:44 PM

pois, alt nem ctrl nem meta aqui, busco depois, relaxa
sabem se existem estudos em música generativa que leva em consideração essas peculiaridades dos instrumentos?

Luiz Casteloes 2:52 PM

me 2:53 PM
((1 2 3) (4 5 6))
dois acordes
(1 2 3 4 5 6)

Yago Franco 2:53 PM
isso

me 2:53 PM
uma melodia

glerm soares 2:54 PM
sim a sacada é saber os melhor objetos pra montar essas listas ;)

me 2:54 PM
isso ae

Yago Franco 2:54 PM
e tambem é uma questão de tentativa e erro. Eu sempre abro o listener e vou testando

me 2:55 PM
se A é (1 2 3) e B é (4 5 6) então (list A B) gera uma lista de listas: ((1 2 3) (4 5 6)) e (concat A B) vai concatenar mesmo (1 2 3 4 5 6)
bem nessa yago
em python é a mesma coisa, tem que manter o avaliador aberto para ir testando

Yago Franco 2:55 PM
isso, ai derrepente vc usa um flatt pra remover os parenteses internos

me 2:56 PM
isso!

glerm soares 2:56 PM
sim, assim como em python eu tou usndo bastante o print

Yago Franco 2:56 PM
não conheço python

me 2:56 PM
yago, manda um python no terminal do mac que vc já conhece, é bem tranquilo
é lisp sem parênteses
:-)

glerm soares 2:57 PM
yago -> http://musicforgeeksandnerds.com/
pra começar com python e partituras é bem bom esse livro

Yago Franco 2:58 PM

Yago Franco 2:58 PM
vcs já mexeram com isadora?

me 3:00 PM
lembro de um pessoal na udesc usando para teatro o isadora, mas nunca mexi yago

glerm soares 3:00 PM
yago, pras coisas que isadora faz eu uso gem do PD

Yago Franco 3:01 PM
eu assisti um trabalho no EIMAS que o cara usava max pro audio e isadora pro video. Muito bacana o resultado.

glerm soares 3:01 PM
o max tem o jitter tb

Yago Franco 3:01 PM
é eu vi que da pra usar o Jitter do max tb, mas parece que o isadora é mais simples e leve

glerm soares 3:02 PM
yago, uma coisa legal pr representação de misca é o Iannix

Yago Franco 3:02 PM
vou procurar

me 3:02 PM
isso, iannix é demais, talvez para algo mais teatral algo como http://animata.kibu.hu/
processing também

Yago Franco 3:03 PM
depois assisto, a internet aqui é uma coisa de cada vez. rs
não precisa nem escrever pro google eles devem estar ouvindo...
tem um path do Pedro (que foi do COMUS) que ele conseguiu uma maneira bacana de coincidir sempre o numero de notas
om-loop

me 3:22 PM
range(3,8) em python?

glerm soares 3:27 PM
ou xrange?
tem haver

me 3:27 PM
isso, xrange é mais rápido
ele foi feito para usar em iterações (tipo for e tals)

glerm soares 3:30 PM
no PD tem um objeto chamado change que filtra repetições

também viajei, ainda não saquei o que é o CL no athena haha
composition language?
só tratar as sublistas dos acordes como se fosse um elemento da lista

Luiz Casteloes 3:46 PM
guilherme, quando voltar avisa...

me 3:52 PM
(x-append (list 1 2 3) (list 1 2 3)) no listener facilita entender

me 3:58 PM
glerm, ótimo livro sobre common lisp (CL): http://www.gigamonkeys.com/book/
lembra um pouco a questão da matemática discreta em oposição a contínua...
dizem que a matemática discreta consegue até ser mais rica
porque vc tem um espaço bem definido para explorar
força vc extrapolar criativamente

glerm soares 4:07 PM
Luiz, de uma olhada depois no Iannix (software partituras alternativas)

me 4:07 PM
doido isso, sempre há necessidade de uma escala, mapeamento...
de um domínio em outro

== Aula 1 (04/09/2013) ==

CAC

Malt, 2006. Pedagogos, fácil acesso. Renato conversou sobre teoria de
conjuntos com ele. Um dos maiores pedagogos em CAC.

CAC tem ~60 anos de idade.

Xenakis.

Definições CAC... de Malt, 2006

Definições do Cope, 2008.

Schaffer, spectralistas, debussy, estão preocupados com o resultado,
na escuta, e não no simples experimentalismo.

eu achei que o google guardava os chats
acho que perdemos o chat aqui do hangout

automata
16:51

Luiz Casteloes
16:52
a gente pode ir aperfeiçoando isso ao longo do curso, tranquilamente...

glerm soares
16:52
o chat do irc está guardado

automata
16:52
acho que gravei o vídeo, estou tentando converter

glerm soares
16:52
Ola Carmem

automata
16:52
olá carmem!

Luiz Casteloes
16:52
(a questão da interatividade, registro, etc.)

automata
16:53
sobre os trabalhos de conversão de imagens em música

glerm soares
16:53
Na próxima aula já vamos trabalhar algo com OM?

automata
16:53
estamos desenvolvendo um trabalho aqui
de análise de imagens
mas não temos a parte musical
acho que podemos dialogar
perfeito
ótimo

glerm soares
16:55
Esta semana pretendo trabalhar com uma biblioteca de análise chamada music21, o Vilson e Renato já fizeram algo com ela também

automata
16:55
sim, temos trabalhado com análise das influências do scarlatti em beethoven, o domenico
opa opa voltei
desculpem, caí aqui

glerm soares
16:57
Vejo que nos patches vocẽ trabalha com umas coisas do tipo "perfil melódico" tirado de contornos de formas

automata
16:58
isso, o contorno de formas (curvatura) temos aqui, então podemos dar um jeito de conversar gerando esses perfis melódicos

glerm soares
16:58
Eu acho que o ideal é fpormalizar os algoritmos
*formalizar

automata
16:58
aquele script das triangulações glerm
legal
aqui mais detalhes sobre a análise de pinturas que estamos fazendo https://www.writelatex.com/329602ypmdzp

glerm soares
16:59
Acho bom entender os algoritmos

automata
17:00
também acho legal
poderíamos ir tentando converter para outras linguagens/tecnologias e ao mesmo tempo brincando/aprendendo OM
legal essa dinâmica

glerm soares
17:01
Uma coisa que quero trabalhar nos próximos Eu estou querendo focar no conceito de "assinatura"
que o David Cope usa

automata
17:01
massa glerm, quero acompanhar isso também
legal

glerm soares
17:01
eu vou tentar dar uma formalizada nisso até a proxima aula

automata
17:03
parece que Renato chegou a conversar com Malt sobre os trabalhos dele com teoria de conjuntos
não ouvi todas
as apontadas na wiki

glerm soares
17:07
eu conheço algumas e ouvi outras, mas mostre o que preferir
qual o link?

automata
17:07
qual link?

Luiz Casteloes
17:07
hiller e xenakis
1as obras de CAC

glerm soares
17:08
supite Illiac?

Luiz Casteloes
17:08
isso

glerm soares
17:08
suíte

Luiz Casteloes
17:08
não precisa ouvir tudo

glerm soares
17:08
qual Xenakis?

Luiz Casteloes
17:08
st
'tá lá também

glerm soares
17:08
ah ok
nos links

Luiz Casteloes
17:14
voltando...

glerm soares
17:14
ok

Luiz Casteloes
17:14
conseguiram ouvir um trecho de cada?

glerm soares
17:14
ouvindo as duas xenakis
Illiac eu ja conhecia

Luiz Casteloes
17:15
qual a impressão?
ou pressão...

glerm soares
17:15
priincipalmente nesta Achorripsis

Luiz Casteloes
17:15
ou (de)pressão...

glerm soares
17:15
da pra perceber que há uma preocupação grande com a alternancia dos timbres
Até onde consegui acha de documentação o Hiller fazia algo semelhante ao "jogo de dados de Mozart" recombinando partes ja preparadas
*achar

automata
17:17
parece maquínico realmente
1o
não tanto no 2o

glerm soares
17:18
Uma pergunta

automata
17:18
o que é CAO e EAO?
deepblug
blue*
ah ok
CMA == CGC?
ok

glerm soares
17:30
Tem um exemplo interessante de livecoding nos links do Luiz

automata
17:30
acho que até o 'produto' final de cada (diferido/real) é para um contexto diferente

glerm soares
17:30
onde ele subsitui o gesto do pianista pelo gesto do programador

automata
17:31
também gosto desse https://vimeo.com/50061269
acho muito difícil 'gostar' de ouvir livecoding se não durante a performance
http://wiki.nosdigitais.teia.org.br/FooBarBaz

glerm soares
17:32
Se tudo tem que ser em Mas se fosse pensar na literatura por exemplo, tempo real não existiriam mais obras literárias, só tweets?

automata
17:33
massa, happenings?

glerm soares
17:33
A questão da maturação da idéia é interessante como conceito.

automata
17:34
tempo diferido seria um conjunto de momentos de tempo real?
tempo reais passados
ops, momentos passados
é, livecoding acho próximo ao jazz, realmente
há preocupação com a máquina compositor mas e a máquina escuta/crítica?
pontilhismo
preocupação com o fenômeno físico, tentando figurar a natureza
jogando notas aqui, pensando alto
3) bastante sensível em tentar mapear imagem em som
cor
5) pasteurização na música eletroacústica/eletrõnica
humanizar a máquina, sonho da IA forte
e atualmente da computação afetiva

glerm soares
17:48
Queria deixar uma pergunta que senti falta - como pensar o "corpo" do instrumentista nisso (pré e pós composição)...

automata
17:48
massa glerm
glerm, acho que tamos te ouvindo, não?

glerm soares
17:49
sim
isso
ainda não

automata
17:51
não li
sensoriamento
máquina escuta/crítica

glerm soares
17:52
existe alguem pensando a fundo o "machine learning" em musica?
(máquina aprendendendo com o gesto do mpusico)

automata
17:53
pessoal pesquisa machine leaning para classificação de gêneros e compositores
mas para entendimento do gesto, não sei
ccrma?

glerm soares
17:54
aprendizado por "tentativa e erro" - tipo maquinas que fazem reconhecimento de voz porque coletam milhares de palavras da mesma voz

automata
17:54
lembro de uma pesquisa sobre análise dos códigos em uma performance de livecoding para auxílio enquanto o intérprete tocava

glerm soares
17:55
alguns algoritmos de open computer vision usam machine learning por exemplo (openCV)
ou bots como o cleverbot

automata
17:55
glerm, encher o intérprete de sensores e usar machine learning para analisar?

glerm soares
17:55
(bots de chat)
vilson, sim mas seria preciso ter critérios para categorizar este corpus

automata
17:56
gestos
topo o que tiverem em mente :-)
não
baixinho

glerm soares
17:57
Eu vou trabalhar em paralelo com umas idéias da minha dissertação e tentar ver o que aprendo sozinho do OM pra trazer umas duvidas... basicamente vou tentar entender os algoritmos
... pergunta de novo por favor

automata
17:57
vou também 'fuçar' no OM
interessante Carmem

glerm soares
17:58
ok

automata
17:58
seria uma ideia...
talvez relacionar o gesto (posição do braço, do corpo...) com a música
isso

glerm soares
17:59
é o que estou insitindo em buscar em trabahos
como o do David Cope

automata
17:59
teria que experimentar

glerm soares
17:59
a busca de assinaturas
em um corpus
para gerar padrões de similaridade

automata
17:59
isso glerm, vc quer no nível simbólico

glerm soares
17:59
- respondendo a Carmem
ta ali acima

automata
17:59
manda ver

glerm soares
18:00
Carmem, pense no deepblue

(16:26:52) automata: effeerre pediu para o Kreidler imitar ele? hahaha foda

(16:27:51) automata: glerm, o Kreidler fez? respondeu?

(16:28:19) glerm: acho que respondeu que curtiu o livro dele mas que tava super ocupado agora, essas coisas

(16:28:48) glerm: acho que ele mandou o Elefante de Marfim pra ele

(16:29:07) automata: não conheço acho, xo ver

(16:29:14) glerm: é bem massa

(16:29:29) automata: http://www.oelefantedemarfim.cc/

(16:29:31) automata: ?

(16:29:57) glerm: isso

(16:31:24) glerm: olha aqui - o inverso de fazer som com imagem -

(16:33:50) automata: massa o Elefante de Marfim, fr regassa

(16:34:41) automata: eu vi essa do bruno vianna, muito legal, transforma intensidade do sinal em intensidade de cinza em leitura de imagem corrida... algo assim

(16:35:52) automata: isso, esse vídeo comecei a ver ontem, viagem

(16:36:15) automata: glerm, o hybrid soltou a ideia de transformar esse curso CAC em um coursera

(16:37:59) automata: mesmo princípio do sinal analógico de tv será?

(16:41:25) glerm: tem que ver os detalhes do protocolo que ele ta usando

(16:41:30) glerm: o que é coursera?

(16:50:58) glerm: alo

(17:19:39) hybrid saiu da sala (quit: Ping timeout: 260 seconds).

(17:22:30) automata: glerm, coursera é aquela interface web onde rolam cursos abertos, https://www.coursera.org/

(17:22:32) lalenia: Title: Coursera.org (at www.coursera.org)

(17:22:35) automata: tem coisa bastante fina

Notas sobre a disciplina de CAC (Composição Assistida por Computador) - Música e Interdisciplinaridade

== Aula 1 (04/09/2013) ==

CAC

Malt, 2006. Pedagogos, fácil acesso. Renato conversou sobre teoria de
conjuntos com ele. Um dos maiores pedagogos em CAC.

CAC tem ~60 anos de idade.

Xenakis.

Definições CAC... de Malt, 2006

Definições do Cope, 2008.

Schaffer, spectralistas, debussy, estão preocupados com o resultado,
na escuta, e não no simples experimentalismo.

eu
16:53
sobre os trabalhos de conversão de imagens em música
glerm soares
16:53
Na próxima aula já vamos trabalhar algo com OM?
eu
16:53
estamos desenvolvendo um trabalho aqui
de análise de imagens
mas não temos a parte musical
acho que podemos dialogar
perfeito
ótimo
glerm soares
16:55
Esta semana pretendo trabalhar com uma biblioteca de análise chamada music21, o Vilson e Renato já fizeram algo com ela também
eu
16:55
sim, temos trabalhado com análise das influências do scarlatti em beethoven, o domenico
opa opa voltei
desculpem, caí aqui
glerm soares
16:57
Vejo que nos patches vocẽ trabalha com umas coisas do tipo "perfil melódico" tirado de contornos de formas
eu
16:58
isso, o contorno de formas (curvatura) temos aqui, então podemos dar um jeito de conversar gerando esses perfis melódicos
glerm soares
16:58
Eu acho que o ideal é fpormalizar os algoritmos
*formalizar
eu
16:58
aquele script das triangulações glerm
legal
aqui mais detalhes sobre a análise de pinturas que estamos fazendo https://www.writelatex.com/329602ypmdzp
glerm soares
16:59
Acho bom entender os algoritmos
eu
17:00
também acho legal
poderíamos ir tentando converter para outras linguagens/tecnologias e ao mesmo tempo brincando/aprendendo OM
legal essa dinâmica
glerm soares
17:01
Uma coisa que quero trabalhar nos próximos Eu estou querendo focar no conceito de "assinatura"
que o David Cope usa
eu
17:01
massa glerm, quero acompanhar isso também
legal
glerm soares
17:01
eu vou tentar dar uma formalizada nisso até a proxima aula
eu
17:03
parece que Renato chegou a conversar com Malt sobre os trabalhos dele com teoria de conjuntos
não ouvi todas

17:30
Tem um exemplo interessante de livecoding nos links do Luiz
eu
17:30
acho que até o 'produto' final de cada (diferido/real) é para um contexto diferente
glerm soares
17:30
onde ele subsitui o gesto do pianista pelo gesto do programador
eu
17:31
também gosto desse https://vimeo.com/50061269
acho muito difícil 'gostar' de ouvir livecoding se não durante a performance
http://wiki.nosdigitais.teia.org.br/FooBarBaz

17:32
Se tudo tem que ser em Mas se fosse pensar na literatura por exemplo, tempo real não existiriam mais obras literárias, só tweets?
eu
17:33
massa, happenings?
glerm soares
17:33
A questão da maturação da idéia é interessante como conceito.
eu
17:34
tempo diferido seria um conjunto de momentos de tempo real?
tempo reais passados
ops, momentos passados
é, livecoding acho próximo ao jazz, realmente
há preocupação com a máquina compositor mas e a máquina escuta/crítica?
pontilhismo
preocupação com o fenômeno físico, tentando figurar a natureza
jogando notas aqui, pensando alto
3) bastante sensível em tentar mapear imagem em som
cor
5) pasteurização na música eletroacústica/eletrõnica
humanizar a máquina, sonho da IA forte
e atualmente da computação afetiva
glerm soares
17:48
Queria deixar uma pergunta que senti falta - como pensar o "corpo" do instrumentista nisso (pré e pós composição)...
eu
17:48
massa glerm
glerm, acho que tamos te ouvindo, não?
glerm soares
17:49
sim
isso
ainda não
eu
17:51

sensoriamento
máquina escuta/crítica
glerm soares
17:52
existe alguem pensando a fundo o "machine learning" em musica?
(máquina aprendendendo com o gesto do mpusico)
eu
17:53
pessoal pesquisa machine leaning para classificação de gêneros e compositores
mas para entendimento do gesto, não sei
ccrma?
glerm soares
17:54
aprendizado por "tentativa e erro" - tipo maquinas que fazem reconhecimento de voz porque coletam milhares de palavras da mesma voz
eu
17:54
lembro de uma pesquisa sobre análise dos códigos em uma performance de livecoding para auxílio enquanto o intérprete tocava
glerm soares
17:55
alguns algoritmos de open computer vision usam machine learning por exemplo (openCV)
ou bots como o cleverbot
eu
17:55
glerm, encher o intérprete de sensores e usar machine learning para analisar?
glerm soares

eu
17:57
vou também 'fuçar' no OM
interessante Carmem
glerm soares
17:58
ok
eu
17:58
seria uma ideia...
talvez relacionar o gesto (posição do braço, do corpo...) com a música
isso
glerm soares
17:59
é o que estou insitindo em buscar em trabahos
como o do David Cope
eu
17:59
teria que experimentar
glerm soares
17:59
a busca de assinaturas
em um corpus
para gerar padrões de similaridade
eu
17:59
isso glerm, vc quer no nível simbólico

Massa

2013-06-04T04:02:53Z

VilsonVieira:

==MASSA é Música e Áudio em Sequências e Séries Amostrais.==

A massa é um conjunto de scripts que implementam computacionalmente
as relações descritas na dissertação '''Música no áudio digital: descrição psicofísica e caixa de ferramentas'''.

Para clonar o repositório:

$ git clone git://labmacambira.git.sourceforge.net/gitroot/labmacambira/massa

Caso você tenha usuario no Sourceforge habilitada para os repositórios macambiras, pode baixar
com direito a escrita:

$ git clone ssh://<usuario>@labmacambira.git.sourceforge.net/gitroot/labmacambira/massa

No repositório, a pasta '''dissertacao/''' contém uma descrição das relações implementadas em código.
A pasta '''scripts/''' possui os arquivos que implementam em Python as relações descritas.
A pasta '''musicas/''' possui scripts que sintetizam músicas com base nos princípios expostos e implementados.
A pasta '''snippets/''' possui scripts usados para as figuras da dissertação e que implementam outras
utilidades, como a ISO226 que é o último padrão adotado das curvas iso-audíveis.

== Instruções para leitura da dissertação ==

Cada relação analítica presente na dissertação possui seu equivalente em código Python. Assim, recomenda-se a leitura da dissertação e dos códigos em paralelo.

Antes de tudo, assegure-se de ter Python e Git instalados em seu sistema (aqui instruções para instalação em GNU/Linux Ubuntu):

$ sudo apt-get install python git python-setuptools

Também é necessária a instalação de Scikit Audiolab, em sua última versão. Por sua vez, Scikit Audiolab depende da última versão de libsndfile. Para instalar ambos, faça:

$ wget http://www.mega-nerd.com/libsndfile/files/libsndfile-1.0.25.tar.gz
$ tar -xvzf libsndfile-1.0.25.tar.gz
$ cd libsndfile-1.0.25/
$ ./configure
$ make
$ sudo make install

$ git clone https://github.com/cournape/audiolab.git
$ cd audiolab/
$ sudo python setup.py install

Faça o download do repositório da massa:

$ git clone git://labmacambira.git.sourceforge.net/gitroot/labmacambira/massa

Para cada seção, leia o código e execute os scripts encontrados nos sub-diretórios da pasta '''dissertacao/''' referentes à seção. Por exemplo, para a seção 2.1:

$ cd secao2.1/
$ python eqs2.1.py

Cada script pode gerar arquivos de áudio (.wav) e gráficos (.png) no diretório corrente, dependendo da situação.

VilsonVieira:

We provide information on how to run free software and general free software development on Mac OS X.
Our instructions are not exactly radically about pure "free" software, but focus on advanced usage and software development that may be useful for creating free software.

'''This information may not be optimal or well-automated as the current contributor to this article is not very much experienced with Mac OS X.'''

== Configuring Mac OS X for development ==
* I didn't use a package manager at first and installed the following by going directly to the websites
** Firefox, Chrome
** Git
** Google voice plugin
** Libreoffice
** Transmission bit torrent client
* Install an IRC client from the app store
* Install XCode from the app store
** Go to XCode -> Preferences -> Downloads and install command line tools for xcode
* Change capslock to control key in system preferences -> keyboard ->
* Learn the trackpad gestures. They're useful. Activate the four finger gesture for exposee
* Turn off stupid autocorrection
* Vim
** install macvim if you want to have something like gvim; otherwise its already in the system
** Firefox is still the best browser for wiki editing. Install its all text plugin and use macvim as the app.
* /home vs /User
** I disabled automount of /home then symlinked to my home directory using this [http://apple.stackexchange.com/questions/44058/mac-os-x-how-to-symlink-home-to-users]
* Function keys to behave as function keys
** System Preferences -> Keyboard -> Keyboard -> checkbox "Use all F1, F2, etc. as standard function keys"
* iTerm2 is a better terminal than Terminal [http://sysd.org/terminal-velocity]
* I installed Latex from downloading a torrent form the Mactex website. Once you install it, to get a 'latex' or 'pdflatex' command in the terminal without restarting your computer you need to issue:
eval `/usr/libexec/path_helper -s`
since in OS X there is a path helper that updates system-wide PATH according to ls /etc/paths.d/* for you.
* X11. I installed XQuartz directly from the site's .dmg package. Rumors on the web say the macports xorg package has some issues.

==== What I've installed using Macports ====

Some apps are newest in macports and are easier to install using it than downloading installers from each website.
sudo port install kdenlive gimp mplayer2 ddd pdftk okular evince nautilus inkscape xfig yasm zlib bzip2 faac lame speex libogg libvorbis libtheora libvpx x264 XviD openjpeg opencore-amr freetype

=== Java ===
* The maven build system already comes in Mac OS X mountain lion
* I installed JDK by typing java in google and clicking on the oracle website. If you need java 6 then you need to logon to developer.apple.com and get it there.

=== Package Managers for Programming ===
Currently there are many package managers for Mac OS X emulating the ones available in Linux. In fact, the main advantage of linux I've perceived so far is the availability of solid package management so that you can get a full-fledged development system up and running from scratch automatically. In Mac OS not everything can be done automatically, and dev packages do not seem to be as rock solid as in GNU/Linux.
* Fink
** This seems to be mentioned in building many free software such as [[Scilab]] and [[Pd]]. It doesnt seem to be user friendly (for mountain lion one has to install fink from source)
** From what I read, has many binary packages and works like apt-get
* Macports
** User friendly, but installs a layer of software in parallel to whats already in Mac OS X.
** Building mozilla firefox supports macports
** Latest kdenlive, gimp are available in macports
** ImageMagick recommends macports
** From what I read, no binary packages. But that's good since there's nothing like building from source from a developer's point of view.
** '''Word has it that macports can have old/outdated packages, that's why people have switched to Homebrew. Many people use both.'''
** Latest kdenlive video editor is only easily installed using Macports
** Mplayer has many builds in macports, including mplayer2 and development snapshots
* Homebrew
** Somewhat user friendly and reuses most software thats already in Mac OS X - better integration with the system.
** I've heard it on the web that it doesn't have as many packages as Macports,
** An experienced friend said homebrew is sometimes unstable, having broken installations and packages
** Homebrew has newer packages than macports according to rumors, however it seems to have fewer packages
** Building mozilla firefox supports homebrew
** '''My experienced friend uses both macports and homebrew'''
** Mplayer2 doesn't seem to be available in homebrew

=== Webcams ===
* For the [[PS3_Eye]] I installed macam from the website, but it doesn't work properly [https://sourceforge.net/tracker/?func=detail&aid=3552330&group_id=44375&atid=43934] #fail

=== System Automation ===
* Configuring mac os x from the commandline [https://t.co/UnsH1dgcgA]
* [http://boxen.github.com Boxen]

== Installing Linux on a Mac ==

There are two options, running Linux on top Mac OS X using something like VMware, parallels desktop, virtualbox,
or installing linux natively.

=== Macbook pro early 2013 ===
I will here report my experience on installing linux on a early 2013 macbook pro.

Install All Required Application

Before it's start, install your system with required application bellow :

sudo apt-get install build-essential automake make

Download the Patch

Download Following Source for compiling the driver (Broadcom BCM4331) and patching the kernel.

compat-wireless
the patches, here
the latest version of bw43-fwcutter (version 015)
Broadcom's proprietary driver to extract the firmware

Patching and Compiling

Make a folder named bcm4331 and put all file you have download there, then

# tar xf compat-wireless-2011-08-27.tar.bz2
# tar xf patch_bcm4331.tar.bz2
# cd compat-wireless-2011-08-27/
# patch -p1 < ../bcm4331-1.patch
# patch -p1 < ../bcm4331-2.patch
# patch -p1 < ../bcm4331-3.patch

Next, enable the driver

# scripts/driver-select b43

Next, go to config.mk, find row 276 and remove `#`, so that become

CONFIG_B43_PHY_HT=y

Compile and Install the driver

# make
# sudo make install

Unpack and Compile b43-fwcutter:

# tar xf b43-fwcutter-015.tar.bz2
# cd b43-fwcutter-015
# make

Extract the firmware

# tar xf ../broadcom-wl-5.100.138.tar.bz2
# export FIRMWARE_INSTALL_DIR="/lib/firmware"
# sudo ./b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" broadcom-wl-5.100.138/linux/wl_apsta.o

Unload all related modules that use wireless

# cd compat-wireless-2011-08-27
# sudo make wlunload

Reboot your system and load compiled Wireless b43 module

# sudo modprobe b43

Next, add the b43 to the list of modules so the system will load them on startup (the module is not automatically loaded).

# cp /etc/modules /etc/modules.old
# echo "b43" | sudo tee -a /etc/modules

Next, Sometimes the driver does not work properly after suspend and hibernate. It is necessary to unload the module before putting the laptop to sleep and to reload it after wake up. For Ubuntu, it is sufficient to create the file (or append to the file)

# cp /etc/pm/config.d/default /etc/pm/config.d/default.old
# echo 'SUSPEND_MODULES="b43"' >> /etc/pm/config.d/default

Yes it is.. I realy hope this will fix the MBP Wireless problem issue.

From http://www.ubuntubuzz.com/2011/10/macbook-pro-wireless-broadcom-bcm4331.html

=== Atualizar fw do AirPort quando atualizar Ubuntu ===

Os arquivos estão em ~/tmp.

</pre>

Notas
*1* Neste exemplo agentes interagem com igual probabilidade P = 1/(numero de arestas na rede), ou seja igual probabilidade;
*2* Cada agente tem uma propriedade, numero real, alocado em fields;
*3* A interacao eh um filtro de altas frequencias no atributo do no/agente, ou seja a interacao e homofilica/homogeinizadora;
*4* A rede eh aleatoria.
*5* Para gerar modelo de agentes em redes complexas diferente, mais realista, eh necessario generalizar qualquer um destes pontos no local indicado no codigo atraves dos numeros das notas.

== Processamento de Imagens ==

'''((( Ver também [[PythonImagem]] )))'''

=== Como abrir uma imagem? ===

<pre>
from PIL import Image
im = Image.open('foo.jpg')
</pre>

=== Como converter em escala de cinza? ===

<pre>
im_cinza = im.convert('L')
</pre>

=== Como acessar cada canal de cor da imagaem? ===

<pre>
im_r = im.split()[0]
im_g = im.split()[1]
im_b = im.split()[2]
</pre>

=== Como equalizar uma imagem por histograma? ===

<pre>
from PIL import ImageOps
im_eq = ImageOps.equalize(im_cinza)
</pre>

=== Como aplicar uma função qualquer com janelamento de 3x3? Ou, como aplicar um filtro qualquer com janelamento? ===

No caso, vamos aplicar a função entropia em cada pixel da imagem. A função entropia recebe como argumento os 9 vizinhos do pixel, já que o tamanho da janela (argumento size da função generic_filter) é equivalente a 3. A função entropia retorna o novo valor do pixel.

<pre>
from scipy import ndimage

def entropia(viz):
viz = list(viz)
qtd = [viz.count(x) for x in viz]
prob = [viz[i]/qtd[i] for i in range(len(viz))]
return n.sum([-x*n.log(x) for x in prob if x != 0])

im_entropia = ndimage.generic_filter(im_cinza, entropia, size=3)
</pre>

=== Como calcular o valor de entropia de uma imagem inteira? ===

<pre>
def entropia(im, nbr_bins=256):
hist = im.histogram()
hist_length = sum(hist)
samples_probability = [float(h) / hist_length for h in hist]
return sum([-p * log(p) for p in samples_probability if p != 0])

v_entropia = entropia(im_cinza)
</pre>

=== Como calcular os valores de energia de uma imagem? ===

<pre>
from scipy import fftpack
energias = fftpack.fft2(im_cinza).real**2 + fftpack.fft2(im_cinza).imag**2
</pre>

Calculando a energia de janelas de uma imagem, determinadas em um particionamento em grade da imagem. A recomposicao da imagem original (s[0] x s[1]) e feita mas agora no espaco de frequencias bi-dimensionais.

<pre>
from scipy import fftpack
import Image
import numpy as np

img = Image.open('/r.0.jpg');
img = img.convert('L');
s = [img.size[0], img.size[1]];
pttlen = 80; # numero de blocos por dimensao da particao na imagem (total pttlen x pttlen = 6400 neste caso)
arr = np.array(list(img.getdata()));
arr = arr.reshape((800,800));
energia = dict( [[(i,j), np.log(fftpack.fft2(arr[i*s[0]/pttlen:(i+1)*s[0]/pttlen,j*s[1]/pttlen:(j+1)*s[1]/pttlen]).real**2 + fftpack.fft(arr[i*s[0]/pttlen:(i+1)*s[0]/pttlen,j*s[1]/pttlen:(j+1)*s[1]/pttlen]).imag**2)] for i in range(pttlen) for j in range(pttlen)]);

# This rebuilds the original imagem in the frequency domain of window length (s[0]/pttlen)x(s[1]/pttlen)
fourierimage = Image.new('L',(s[0],s[1]),255);
for v in energia.keys():
b0 = Image.new('L',(s[0]/pttlen,s[1]/pttlen),255);
data = energia[v];
data = data.reshape(-1);
data = data.tolist();
b0.putdata(data);
fourierimage.paste(b0,(v[0]*(s[0]/pttlen),v[1]*(s[1]/pttlen)))
fourierimage.show();

</pre>

=== Como calcular convex hull de uma imagem binária? ===

Convex hull preenche as regiões convexas de uma imagem binária, gerando uma "mancha", sem essas concavidades. A razão entre a área da imagem original e a área encontrada pelo convex hull é uma boa medida para determinar o quanto uma região é circular ou não. Quanto mais circular, mais próximo de 1.0.

== 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 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:'''

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;

2) Work on Vivace issues;

3) Screencast performances using Vivace, maybe public ones, to test it on a real scenario;

=== 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 maillist 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.

=== [[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.

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.

=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.
