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.

[[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.

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]].
=== 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:''' The [[AHT]] project is an opportunity to develop and spread cutting-edge technology in a playful manner, which may seem otherwise too hard/unapproachable.
'''Objective:''' Fix some bugs on SOS and extend the concept to other areas, creating a knowledge base around popular culture
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:'''  
'''Suggested Roadmap:'''  


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

== 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?


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;
=== [[Pet]] ===


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


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


'''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.

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


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

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)

[[Scilab]] is a free rapid prototyping environment for numerical algorithm
A collaborative creative coding environment on Web. [http://li7e.org LI7E] focus is on [https://github.com/automata/li7e/wiki/Manifesto collaboration]. Imagine how awesome is to code seeing the results running in real time. And doing this with people all over the world, in the same time. This incredible ideia moves the LI7E project, which aims to bring facilities to code in a collaborative way using creative coding APIs.
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.


'''Objective:''' The main objective is extend LI7E. Connect JavaScript creative libraries and develop a client-server system to support the real time evaluation of the code, in a collaborative and distributed way using nodejs and WebSockets.

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

We are planning to create a plugin to [http://etherpad.org EtherPad] that makes possible to run JavaScript (and maybe other languages) inside of EtherPads and to be programmable collaborative the same way EtherPad already does for common text.
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]]). It is interesting to take a look at [http://worrydream.com/Tangle/ Bret Victor works on "reactive documents"]. It is a kind of documents we are interested to implement using pads.

=== [[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.

<pre>'The increasing dominance of graphic interfaces for music software obscured
3) Get the 3D reconstruction system up and running isolatedly;
the continuing presence of the command-line tradition,
the code writer, the hacker. The code writing of deferred time
computer programming may be assembled out of time order, debugged and optimized.'


--- Simon Emmerson, Living electronic music, 2007</pre>
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.

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


'''Objective:''' Continue the deveopment of the Supybots Macambot, Lalenia and coBots.
[[Imagem:SIP_whitebg.png|right|bottom|alt=SIP toolbox]]
[[Imagem:Leptonica.jpg|right|bottom|alt=Leptonica Image Processing Library from Google]]


'''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
[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.

== Permanent Conference ==
1) Run leptonica and SIP;
[[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
2) Make a contribution to Leptonica (at least a simple bugfix), which will help the student get started;
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.
3) Write the necessary C infrastructure to interface Leptonica image structures with Scilab matrices;


'''Objective:''' Continue the implementation of the Django application Permanent Conference
4) Interface a Leptonica functionality with Scilab and document it thoroghly;


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

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


'''Test version:''' A test version is running at http://hera.ethymos.com.br:1080/confperm
[[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.

== SOS ==
=== [[Scilab]] Fast and Flexible Image (Raster) Display ===
[[Imagem:Sos2.png|right|bottom|alt=SOS]]
[[Imagem:SIP-shot4.png|250px|right|bottom|alt=Scilab]]


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


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

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 uploaded to a public video channel, the text log is also 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

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.

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: pAAinel. Currently, 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

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)

Ágora Delibera

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 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 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 simple mechanism for deliberation;

2) Get in touch with ongoing 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.

Wearable Health Monitor

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

PlayN -- Cross Platform Game Framework originated at Google
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 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.

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.

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. Vivace is a Live coding language that runs in Web browsers using the new Web Audio API for audio processing and Popcornjs to video sequencing. We want to extend Vivace features like the possibility to apply more complex audio synthesis, create processing routines to video, integrate Vivace with threejs to make possible the creation of 3D shapes and text in real time, and work on other 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 reactive documents by Bret Victor and federated wiki by Ward Cunningham. Technically, reacPad is a plugin to 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 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

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 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.

Scientific Computation

SIP + Scilab

SIP toolbox
Leptonica Image Processing Library from Google

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 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

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

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 imshow function in SIP, the Scilab Image Processing toolbox.

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


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

Suggested Roadmap:

1) Understand Supybot and its plugins;

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

3) Study Python NLTK (Natural Language Toolkit);

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

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

Permanent Conference

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.
