Google Summer of Code: Participating Organizations

As I was paging through the Google Summer of Code site this morning, I realized that I recognized less than half of the participating organizations. Ten minutes and twenty-five lines of Python later, I had all their descriptions in a single page for easier printing. (Note: it was only this easy because Google’s websters had taken the time to put in clearly-labelled div’s — thanks, Google.) So, here they all are — hope it’s useful.

BZFlag is maintained by a rather large, active, and distributed base of users from all around the world. The project is one of the most successful and sustained cross-platform open source games ever with an active developer, administrative, and player community. With more than a million downloads in the last five years alone, more than 200 players online at any time of day or night, and having been under active development since 1992, the project has actually become even more popular over the years as the game continues to grow and as improvements are made to BZFlag.

Our developer community presently consists of a primary core of developers that have made extensive contributions to the game and remained active over many years, along with about a dozen apprentice-level developers that are coming up in the ranks, and about two dozen peripheral/casual developers, extension developers, and web integration programmers. All of our project developers live and collaborate on the #bzflag IRC channel exclusively, which is the hub of all of our development and network infrastructure administration. From IRC, we administer network operations for the approximate 10k+ active player base and 200+ public servers. As we are predominantly a globally distributed network-oriented game, we also maintain the public server listings, provide player tracking, network statistics, global authentication, user and group management, abuse and ban controls, player support, league management, and more.

Our group is organized to the extent of coordinating and holding developer meetings (via IRC) as needed for important development discussions. We operate via a benevolent dictatorship combined with a meritocracy amongst the core developers. Extensive discussions are held for any changes to the game that affect the ‘spirit’, environment, and types of interactions found in the game, including the addition of new features such as new flags and enhanced graphics. We also serve as a support arm to our user community assisting them with anything from how to get started with the game to setting up their own server to writing their own new extensions to the game.

Another goal of Casetta project is to write documentation about several proprietary file formats of calculator, to help everyone to work in this domain.

Center for the Study of Complex Systems (CSCS), University of Michigan

The Center for the Study of Complex Systems (CSCS) is a broadly interdisciplinary unit within the College of Literature, Science and the Arts (LSA) of the University of Michigan, Ann Arbor, Michigan. CSCS’s mission is to encourage and facilitate research and education in the general area of nonlinear, dynamical and adaptive systems. Participating faculty represent nearly every college of the University. The Center is based on the recognition that many different kinds of systems which include self-regulation, feedback or adaptation in their dynamics, may have a common underlying structure despite their apparent differences. Moreover, these deep structural similarities can be exploited to transfer methods of analysis and understanding from one field to another. In addition to developing deeper understandings of specific systems, interdisciplinary approaches should help elucidate the general structure and behavior of complex systems, and move us toward a deeper appreciation of the general nature of such systems.

You can use the components that Dojo provides to make your web sites more useable, responsive, and functional. With Dojo you can build degradeable user interfaces more easily, prototype interactive widgets quickly, and animate transitions. You can use the lower-level APIs and compatibility layers from Dojo to write portable JavaScript and simplify complex scripts. Dojo’s event system, I/O APIs, and generic language enhancement form the basis of a powerful programming environment. You can use the Dojo build tools to write command-line unit-tests for your JavaScript code. The Dojo build process helps you optimize your JavaScript for deployment by grouping sets of files together and reuse those groups through ‘profiles’. In addition to all this power for your web applications, you can use the power of the Dojo Toolkit in any sane JavaScript environment such as Mozilla Rhino. With over 100,000 downloads of our 0.4 release, its also pretty popular and high-profile.

In addition to the Dojo Toolkit, the OpenRecord ( and Cometd ( projects are part of the Dojo Foundation.

The ikiwiki project aims to develop a general-purpose wiki engine, with particular emphasis on personal wikis, project wikis, blogs, and collaborative software development. We provide several features unique or uncommon amongst wikis:

  1. Rather than inventing yet another simplistic, linear revision control system, ikiwiki uses a standard version control system such as Subversion or Git. You can edit a wiki by committing to your repository, as well as through a traditional web interface. This makes ikiwiki ideal for collaborative software development; just keep your wiki in version control next to your software. You can also take advantage of the features of these systems; for instance, you can keep a local branch of your wiki via Git.
  2. You can turn any set of pages into an inline news feed, complete with RSS and Atom support. You can run your weblog on ikiwiki (and many people do), run a Planet-like aggregator for external feeds, or keep a TODO and bug list with tags for completed items.
  3. ikiwiki provides a wiki compiler, designed to transform your wiki content into a set of static pages. You can then serve these pages as static content. ikiwiki will not fall over during a Slashdotting, because page views don't require the ikiwiki CGI; as long as Apache can keep up, your site will survive. Furthermore, you can choose whether you want to run the ikiwiki CGI for web edits or only handle commits to the underlying version control system; you can even run ikiwiki privately and just manually copy the content to another server. So if you want to put a wiki up on a server without installing any software on that server, try ikiwiki.

National Evolutionary Synthesis Center (NESCent), Phyloinformatics Group

The NESCent Phyloinformatics group is a partnership of the NESCent Informatics program with developers from a number of widely popular open-source life-science programming toolkits (BioPerl, Biojava, Biopython, Bioruby, BioSQL; collectively referred to as the Bio* projects, see and software tools for phylogenetic analysis. This resulted in the first ever Phyloinformatics Hackathon ( held in Durham, NC, in December 2006. The objective of the group is to further seamless interoperability and the consistent support of data exchange standards in all areas of evolutionary bioinformatics.

The National Evolutionary Synthesis Center (NESCent), is an NSF-funded center located in Durham, NC. Its overall mission is to facilitate synthetic research aimed at addressing fundamental questions in evolution. Synthetic research uses existing primary data from previously published studies and other sources to combine them in new and intelligent ways to address questions of broad significance.

At the core of the mission of the Open Bioinformatics Foundation (OBF), the umbrella organization for the Bio* projects is the promotion of open-source software development in the field of bioinformatics.

Many applications are easily available through pkgsrc, the NetBSD Packages Collection.

Neuros Technology

Neuros is a manufacturer of multimedia devices (audio players, media centers, personal video players) fully committed to the use of open source software and methods for all current and future products. All the source code is released as open source, mostly under the GPL license, and community involvement is a key component both in the design of the devices (with schematics for the hardware freely available) and in the development of software (with regular flow of patches from the community being included in the official repository). The current focus (and focus for SoC) is on the Neuros OSD, nominally a media center/recorder but actually a fully hackable Linux-based general purpose media device which use beyond the original function is fully supported and encouraged.

Nmap Security Scanner

We produce the free and open source Nmap Security Scanner, which will be celebrating its 10th anniversary this year. Briefly, Nmap is a utility for network exploration, administration, and security auditing. It uses IP packets in novel ways to determine which hosts are available online (host discovery), which TCP/UDP ports are open (port scanning), and what applications and services are listening on each port (version detection). It can also identify remote host OS and device types via TCP/IP fingerprinting. To learn more, check out Nmap.Org.


We’re an open source interactive 3D rendering engine for use in games, simulations, interactive art, museum exhibits, scientific visualisation, and plenty of other things.

One Laptop Per Child

One Laptop per Child (OLPC) is a new, non-profit association dedicated to research to develop a $100 laptop—a technology that could revolutionize how we educate the world’s children. This initiative was first announced by Nicholas Negroponte at the World Economic Forum at Davos, Switzerland in January 2005.

Our goal: to provide children around the world with new opportunities to explore, experiment, and express themselves.

Please note that the $100 laptops—not yet in production—will not be available for sale. The laptops will only be distributed to schools directly through large government initiatives.

Note that most of the work OLPC needs done needs to be done as part of other existing projects, though there will be some OLPC specific opportunities as well. We expect work done in various projects should conform to the licensing policies of that project; work on OLPC specific projects will likely be GPL/LGPL/MIT, depending on precise circumstances, to be determined at the time.

Our world continues to be ravaged by a pandemic of epic proportions, as over 40 million people are infected with or dying from HIV/AIDS – most (up to 95%) are in developing countries. Prevention and treatment of HIV/AIDS on this scale requires efficient information management, which is critical as HIV/AIDS care must increasingly be entrusted to less skilled providers. Whether for lack of time, developers, or money, most HIV/AIDS programs in developing countries manage their information with simple spreadsheets or small, poorly designed databases…if anything at all. To help them, we need to find a way not only to improve management tools, but also to reduce unnecessary, duplicative efforts.

As a response to these challenges, OpenMRS formed in 2004 as a open source medical record system framework for developing countries – a tide which rises all ships. OpenMRS is a multi-institution, nonprofit collaborative led by Regenstrief Institute, Inc. (, a world-renowned leader in medical informatics research, and Partners In Health (, a Boston-based philanthropic organization with a focus on improving the lives of underprivileged people worldwide through health care service and advocacy. These teams nurture a growing worldwide network of individuals and organizations all focused on creating medical record systems and a corresponding implementation network to allow system development self reliance within resource constrained environments. To date, OpenMRS has been implemented in several African countries, including South Africa, Kenya, Rwanda, Lesotho, Uganda, and Tanzania. This work is supported in part by organizations such as the World Health Organization (WHO), the Centers for Disease Control (CDC), the Rockefeller Foundation, and the President’s Emergency Plan for AIDS Relief (PEPFAR).

The Project is an international community of volunteers and sponsors including founding sponsor and primary contributor, Sun Microsystems. develops, supports, and promotes the open-source office productivity suite, supports the Open Document Format for Office Applications (OpenDocument) OASIS Standard and is available on major computing platforms in over 65 languages.


The OpenSolaris project is an open source project which was initially based on the source code for the Solaris operating system. It is a community development effort, providing a forum to collaborate and improve operating system technology. The community has grown from its original roots in Sun Microsystems to be part of a much wider community, incorporating a wider set of interests and ideas, to where it is today, a diverse community of people from many different backgrounds, right across the world contributing to the project.

The governance constitution details the OpenSolaris community organizational structure as a whole,, loosely described as a set of community groups growing up around a set of projects and technologies, each formed by various participants, contributors and core contributors (or members), working under the guidance of the OpenSolaris Governing Board.

The community has well over 20,000 officially registered participants, spread over 40+ community groups, and 50+ user groups worldwide. OpenSolaris also has several distributions derived from the base operating system, including Nexenta, Belenix, and Solaris Express. The number of people contributing code is still relatively small due to some infrastructural barriers in moving the source code management system out behind Sun walls. We have made significant progress in this over the last year, and the beta program for a fully read/write Mercurial repository available is nearing the end.

Oregon State University Open Source Lab (OSU OSL)

The Open Source Lab at Oregon State University exists to help accelerate the adoption of open source software across the globe and aid the community that develops and uses it.

Our goal is to ensure that Plone remains the premier open source content management system and that we broaden its acceptance and visibility worldwide.

Portland State University

We’re the Portland State University Summer of Code team, hoping to participate in a third year of this fine activity. In the past two years, we’ve successfully mentored 11 students through projects in a variety of areas ranging from the immediately practical to the forward-looking esoteric.

Our specialty is projects that clearly benefit the student, the open source community, and society in general, but have no obvious fit in the standard mentoring organizations. In particular, we tend to focus on small-scale or individual, risky but promising open source ‘seed’ projects that we think will grow into something great.

We have a tendency to mentor projects in open technology, including Linux kernel driver work and open hardware/software systems work with a solid code component. That said, a number of our projects have been at the applications level as well; one of our strengths is the ability to track down mentors for a wide variety of different kinds of activity. Portland, Oregon is an amazing place, and we’re lucky to have access to a strong, diverse open source community.

PostgreSQL project

PostgreSQL is a community-driven and owned open source database project, with twenty-one years of development starting at the University of California at Berkeley. We are widely recognized as the second best known open source database.

SCons Foundation: Next-Generation Build Tool

SCons is a cross-platform, next-generation build tool. Unlike most other build tools that invent their own mini-language or wedge a scripting language onto some other configuration file syntax, SCons configuration files are actually Python scripts. The flexibility of Python scripting makes it possible to solve complicated build problems in surprisingly small amounts of maintainable code. Its portability (the only requirement is Python 1.5.2 or later), cross-platform features (extensive support for languages and compilers), and reliability (MD5 file signatures, cache) make it an incomparable tool for build masters in particular, and also for many free software projects.

SCons has been an active project since its founding in 2001. SCons now averages about 7000 downloads per month and has active user and development mailing lists with membership of approximately 450 and 150, respectively, and average monthly traffic of 275 and 100 messages, respectively.

The SCons Foundation was organized in 2003 to hold the copyrights of the SCons source code, and to provide a legal entity for any other organizational necessities (e.g., receiving donations). The Foundation is a Delaware non-profit corporation, but does not currently have 501(c)(3) status.

The ScummVM project allows users to run a variety of classical graphical point-and-click adventure games including Monkey Island, Simon the Sorcerer, Space Quest, and many more. To this end, ScummVM features a complete reimplementation of each supported game engine (Virtual Machine - VM). The number of engines is constantly growing thanks to a very agile and diversified development team.

Portability is one of our main concerns, and hence, ScummVM has been ported to numerous platforms: desktop environments (Windows, Mac OS X, Linux, *BSD, Solaris, …), game consoles (Nintendo DS, PlayStation 2, PlayStation Portable, …), smart phones and PDAs (WinCE, PalmOS or Symbian based), and others (like BeOS, AmigaOS or OS/2).

SilverStripe CMS & Framework

SilverStripe is a PHP5/MySQL-based product that is both a content management system (ala Joomla!, Drupal etc) combined with a rich extendable framework for building websites and web-applications (ala Ruby On Rails, CakePHP). While SilverStripe shares all the buzzwords like MVC, AJAX, Web Standards, we realise how difficult it is to build and maintain complex websites. We are passionate about improving this and differentiate ourselves by putting the user first (important for open source!) and using contemporary technology (e.g. we consciously don’t support PHP4 because making it PHP5+ allows us to do elegant object oriented code as found with RoR).

Its proven itself. In the last month since our past major release, we’ve been quickly endorsed on, on the front page of, had thousands of downloads, and our online community has grown exponentially. Among our blog posts and reviews, is a very informative review at and have been invited to present at OSCON 2007. There are a number of reasons we released the SilverStripe platform open source. Not only does it allow us to give something valuable back after years of using open source products ourselves, we feel we’re evolving the web community with a genuinely innovative product. Finally, we are so convinced SilverStripe will work best when it is widely adopted that we BSD licensed it. We are personally committed to furthering open source and open standards, which fuel the free and interoperable web and directly improves the world we live in.

SIP Communicator is based on the OSGi ( architecture using the Felix implementation from Apache. This makes it very extensible and particularly developer friendly.


Sparse, the semantic parser, provides a compiler frontend capable of parsing most of ANSI C as well as many GCC extensions, and a collection of sample compiler backends, including a static analyzer also called ‘sparse’. Sparse provides a set of annotations designed to convey semantic information about types, such as what address space pointers point to, or what locks a function acquires or releases.

The Linux kernel community uses Sparse to check for common errors in kernel source code. Other projects, such as, have begun to use Sparse as well.


Squeak is a Smalltalk dialect and a programming environment created by many of the original Smalltalk authors. Its first edition was released in 1996, and it’s currently at version 3.9, with a 3.10 version under development. It has spawned many related projects, both non-commercial (such as Squeakland, Croquet, Scratch, Sophie) and commercial (Plopp, DabbleDB). It’s also the main developer platform for the Seaside web framework. The Squeak community is helped by the Squeak Foundation, a small organization dedicated to support Squeak’s development. The Squeak Foundation will be incorporated as a 501(c) non-profit during 2007. The Squeak Foundation takes care of all the bureaucratic tasks for the community (providing funding for server and connectivity costs, etc.); all the other tasks and problems, including technical ones, are handled by the community.

Swarm Development Group

The Swarm Development Group (SDG) was founded in September 1999 as a private, not-for-profit organization to support the development of the Swarm Simulation System (Swarm) and the interests of the group members. The purposes of the SDG are to:

  1. advance the state-of-the-art in multi agent based simulation through the continued advancement of the Swarm Simulation System and support of the Swarm user community
  2. promote the free interchange of multi agent based simulations among computing specialists and the public
  3. develop and maintain the integrity and competence of individuals engaged in the practice of agent based simulation.

Agent-based models (ABMs) are an exciting new approach for learning about and simulating complex systems, and its use is growing rapidly in science and business. As opposed to traditional modeling techniques that represent systems via differential equations for system state, ABMs represent systems as a collection of digital individuals that each have unique characteristics, interact with each other and their environment, and exhibit adaptive behavior.

Swarm is a platform for ABMs that includes: a conceptual framework for designing, describing, and conducting experiments on ABMs; software implementing that framework and providing many handy tools; and a community of users and developers that share ideas, software, and experience. Swarm was the first of several agent-based modeling platforms that are widely used by scientists and students studying complexity in many fields of science. Swarm was originally developed in the mid-1990s by Chris Langton at the Santa Fe Institute and has an active, international user community. Swarm software is a library of Objective-C classes; users code their models in Objective-C, Java, or C++.

The gEDA Project

The gEDA Project is an open-source collaborative involved in creating CAD tools running on Linux (and other unix-like variants) useful for electronic design. Such tools are often called ‘EDA’ tools, an acronym for ‘Electronic Design Automation’. Since our tools are released under the GPL, we are the gEDA Project – short for ‘Gpl’ed EDA’ Project.

The gEDA project is almost nine years old although some components of it date back to 1990. To date, the project has created a set of programs which together provide an end-to-end design flow for printed circuit board (PCB) design. Rather than presenting the user a single, monolithic application for design, we have roughly ten major applications and several dozen minor utilities which are used in a design flow allowing an engineer to take a circuit design from concept, to schematic, to simulation, layout, and to manufacturable PCBs. Therefore, we sometimes refer to our programs as ‘the gEDA Suite’, since our project is an alliance of many different programs worked on by many different developers.

The gEDA Project has perhaps 10 – 20 active developers working on different parts of the tool set. We have seen scores of websites featuring PCBs designed using the gEDA tools. The Project web page logs thousands of downloads of the gEDA Suite per year.

The gEDA Suite is used by students and hobbyists, as well as by professional engineers and consultants. We are currently gaining traction as an educational tool at universities in Europe. Our software has been profiled in EE Times and Linux Journal.

As for formal organization, we are not incorporated as a 503(c), nor do we have any other sort of legal structure. However, the main developers (about 10 people) maintain regular e-mail contact, the developer e-mail list handles several dozen e-mails per day, and the major developers telephone each other regularly. Therefore, we feel confident that we have the required organizational depth to provide support for a Google SoC student.

The GGI Project

The GGI project is a volunteer organization developing portable lowlevel graphics solution frameworks. It provides various libraries, of which the two most fundamental are LibGII (for input-handling) and LibGGI (for graphical output). We want to allow any program using GGI to run on any platform or any backend that can act as a display, requiring at most a recompile. Currently supported plateforms are Linux, Windows (MSYS/MingW, Cygwin), Darwin/MacOSX, FreeBSD, OpenBSD, NetBSD, Solaris. In addition to native display systems (DirectX, Quartz, X etc…), GGI offers a set of additonal backends that can be multiplexed (file, memory, vnc, …). Our work is used in lots of noncommercial and commercial projects (see for a short list).

The Space Telescope Science Institute

The Space Telescope Science Institute (STScI) is the science operations center for the Hubble Space Telescope (HST; in orbit since 1990) and for the James Webb Space Telescope (JWST; scheduled to be launched in 2013). STScI is located on the Johns Hopkins University Homewood campus in Baltimore, Maryland and was established in 1981 as a community-based science center that is operated for NASA by the Association of Universities for Research in Astronomy (AURA). Today, in addition to performing continuing science operations of HST and preparing for scientific exploration with JWST, STScI manages and operates the Multi-mission Archive at Space Telescope (MAST), the Data Management Center for the Kepler mission and a number of other activities benefiting from its expertise in and infrastructure for supporting the operations of space-based astronomical observatories. The staff at STScI consists of scientists (mostly astronomers and astrophysicists), software engineers, data management and telescope operations personnel, education and public outreach experts, and administrative and business support personnel. There are approximately 100 Ph.D. scientists working at STScI, 15 of which are ESA staff who are on assignment to the HST project. The total STScI staff consists of about 350 people.

STScI operates its missions on behalf of NASA, the worldwide astronomy community, and the general public. The science operations activities directly serve the astronomy community, primarily in the form of HST (and eventually JWST) observations and grants, but also include distributing data from other NASA missions (e.g., Far Ultraviolet Spectroscopic Explorer, Galaxy Evolution Explorer) and ground-based sky surveys. The ground system development activities create and maintain the software systems needed to provide these services to the astronomy community. STScI’s public outreach activities provide a wide range of information, on-line media, and programs for formal educators, planetariums and science museums, and the general public. STScI’s award-winning public outreach websites receive millions of hits per month. STScI also serves as a source of guidance to NASA on a range of optical and UV space astrophysics issues.

The STScI staff interacts and communicates with the professional astronomy community through a number of channels, including participation at the bi-annual meetings of the American Astronomical Society, publication of quarterly STScI newsletters and the STScI website, hosting user committees and science working groups, and holding several scientific and technical symposia and workshops each year. These activities enable STScI to disseminate information to the telescope user community as well as enabling the STScI staff to maximize the scientific productivity of the facilities they operate by responding to the needs of the community and of NASA.

The X.Org Foundation supports development of the reference open source implementation of the X Window System. Foundation is an open source project and non-profit corporation dedicated to providing open and free-to-implement multimedia technology as a foundation for an interoperable, level playing field on the internet and other digital distribution networks. Over the past 8 years we have hosted development for all the major patent-free audio and video codec development, including the Vorbis, Speex, FLAC and Theora, the Ogg streaming format, and the Icecast streaming media server.

This year we are also coordinating projects for the Annodex Association under our umbrella. The Annodex project is developing a set of open specifications and open source software to allow the creation of hyperlinked Webs of audio and video integrated with the text-based view of the current Web. Toward this goal, Annodex has done a great deal of work developing tools, browswer plugins and convenience libraries to facilitate adoption of’s lower-level technology. As such the two projects have largely aligned goals, but focus on different levels in the stack.


XMMS2 is the spiritual successor to the very successful XMMS project. The creators of XMMS got together in 2002 and spun out the XMMS2 sister project that is now lead by Tobias Rundstrom and Anders Gustafsson with around 10-15 regular contributors spread over the world (but concentrated in Europe). Our focus has been to separate music playback from the UI in order to provide multiple interfaces and other interesting features. While the code of the music playback engine is starting to mature we have also added features that are expected from modern music players, like a Media library and a powerful way of querying it (Collections).

XWiki is a Java open source wiki under a LGPL license. In addition to being a full-featured wiki, it is also a second generation wiki allowing small collaborative web applications to be written easily and quickly. XWiki has a vibrant community of developers and users, massively expanding during the last year. The community is made of individual users as well as companies around the world which are using XWiki for Intranets and Communities.

One example of an important project built on top of XWiki is Curriki ( which is open source itself and hosted inside XWiki’s source repository. Curriki is an online service for creating and sharing open education resources (based on XWiki and the Google Web Toolkit). Note that we plan to also select projects directly related to the work in progress on Curriki.
