Preferred License: GNU Library or Lesser General Public License (LGPL)

BZFlag is a free online multiplayer cross-platform open source 3D tank battle game that is maintained by an active community of individuals distributed all around the world.. It is one of the most successful and sustained cross-platform open source games ever with an active developer, administrative, and player community. There have been more than a million downloads in the last five years alone and our user base presently consists of more than 200 players online at any time of day or night. The project has actually become more popular over the years as we continue to improve and enhance the game. BZFlag has been under active development since 1992. Our organization is presently comprised of a rather disparate group of individuals that work on BZFlag because they love the game and the community that surrounds it. There are presently 71 individuals entrusted with access to BZFlag core resources including 46 individuals that have committed source code modifications over the project's life span. Our developer base presently consists of 9 documented core 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. Additionally, there are several dozen trusted staffers, server operators, and graphic artists that assist in the day-to-day operations needed by the game for keeping servers up and running, providing server list services, designing artwork, providing network statistics, image hosting, web hosting, and much more. All of our project developers almost exclusively collaborate on the #bzflag Freenode IRC channel, which is the central hub for most of our development discussions, decision planning meetings, game operations, and network infrastructure administration. We operate via a benevolent dictatorship combined with a meritocracy that strives for consensus between the core developers and other involved community members. Extensive discussions are held for any changes to BZFlag that affect the game's traditional "spirit", mood of gameplay, tone of the user environment, and types of interactions possible in the game. These discussions also include considerations whenever there are new features being added such as new flags, enhanced graphics, or changes to the gameplay. We also serve as a support arm to our user community assisting them with anything from how to get started playing to providing assistance with setting up their own server or even helping them write their own new extensions to the game. From IRC, we administer network operations for the approximate 18638 registered player base and for the tens of thousands of unregistered players that engage in more than 10000 daily player sessions across more than 250 public servers. As we are 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 conflict resolution, competitive league management, and user community support.

Center for the Study of Complex Systems, Univ. of Michigan

Preferred License: Apache License, 2.0

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.

FFmpeg is the leading open source multimedia processing library. Nearly any open source program you use that can play a sequence of video images accompanied by sound is probably using FFmpeg to do so. It can decode the most prominent multimedia formats ever created, whether open or proprietary, and can encode to the most important formats as well. As a novelty, FFmpeg can also decode a vast array of impossibly obscure multimedia formats and remains essential for legacy multimedia files (no codec is too old or obscure for this project). Anecdotally, FFmpeg just might be the leading multimedia processing library in existence, as many proprietary applications use it as well (as permitted by the LGPL license). There are many stealth uses as well. YouTube does not advertise how their backend conversion software operates. However, independent, empirical research has demonstrated that YouTube uses FFmpeg to convert videos.

The FreeBSD Project

Preferred License: New BSD license

The FreeBSD Project is a large, mature, and yet relatively tightly nit organization. The FreeBSD Project began 15 years ago in 1993, but is based on the work at Berkeley CSRG with open source revision history going back 30 years to 1978. There are currently over 300 developers with write access to the main revision control system, and hundreds more with access to our Perforce servers for experimental and third party development (this is also where our summer of code students have worked in previous years). We have an active mentoring program to bring all new developers into our community, not just those that we introduce to FreeBSD through the GSoC. There are hundreds of mailing lists, blogs, irc channels, and user groups all detailed on our main website. FreeBSD offers a complete operating system in which students can work, not just a kernel or specific userland stack. This allows for interesting work that spans the userland/kernel boundary, and allows students to build up and package complete modified FreeBSD operating system CDs/DVDs to distribute as ISOs for testing, for example. Relevance to Google : Google has many tens of thousands of FreeBSD-based devices helping to run its production networks (Juniper, Force10, NetApp, etc..), MacOS X laptops, and the occasional FreeBSD network monitoring or test server. Research in FreeBSD security, networking, and other areas has also regularly been adopted recently and throughout its 30 year history to other open source systems. The most recent example from this month is perhaps the JEMalloc allocator which was introduced in FreeBSD 2 years ago and has recently been imported into the Firefox browser, also widely used at Google. This is an exciting time for FreeBSD as Cisco, Juniper, NetApp, Force10, and many other embedded networking device companies are moving towards FreeBSD (Cisco) or upgrading to more modern FreeBSD releases (6.0/7.0 for all the rest). We are also seeing these companies hire open source liaisons and making a concerted effort to contribute more code back.

The gEDA Project

Preferred License: GNU General Public License (GPL)

The gEDA Project is a confederation of roughly 25 developers who work on CAD tools (programs) used for electronic design. The tools are designed to work on Linux and other unices. Some of the tools share a link library, and some are stand-alone. In general, users invoke the programs individually from the unix command line (or a desktop icon). However, we are currently developing a "project manager" which will tie many of the tools into a common entry point. Amongst the tools in the project are: gschem -- a program used to draw schematic diagrams of circuits. pcb -- a program used to design PCBs (printed circuit boards). gerbv -- a program used to view and validate PCBs. Gnucap -- a program used to analyze and simulate analog circuits (equivalent to SPICE). Icarus Verilog -- a program used in design and analysis of logic circuits. gwave -- a program used to view the output of Gnucap, ngspice, and other circuit simulators. In all, the gEDA Project encompasses around 18 programs which may be used in electronic design. A full list of our tools may be found here: Our CAD tools are used by students, educators, hobbiests, small consultants, and even in engineering groups in larger companies.

Preferred License: MIT license

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 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: * 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. * 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. * 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.

Preferred License: GNU General Public License (GPL)

Neuros is a manufacturer of open multimedia devices that is fully committed to the use of open source software and methods for its 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 and OSD 2, an open internet set-top box/media center/recorder. The Neuros OSD can consolidate all a users physical media into a single box (dvds, vhs tapes, home movies) and in the future will be able to do the same with all the downloadable and streaming video as well. The open Neuros OSD platform is an alternative to the closed, walled garden systems distributed by cable and satellite operators.

Nmap Security Scanner

Preferred License: GNU General Public License (GPL)

Nmap ("Network Mapper") is a free and open source utility for network exploration or security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and both console and graphical versions are available.

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 developing countries, including South Africa, Kenya, Rwanda, Lesotho, Uganda, Tanzania, Haiti, Mozambique, Sierra Leone, and Kerala. This work is supported in part by organizations such as the World Health Organization (WHO), the Centers for Disease Control (CDC), the Rockefeller Foundation, the International Development Research Centre (IDRC) and the President's Emergency Plan for AIDS Relief (PEPFAR).

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.

SCons next-generation build system

Preferred License: MIT license

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 not only for build masters but 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.

ScummVM is a collection of Virtual Machines which allow a variety of commercially available graphical point-and-click adventure games to run on modern hardware, often with improved features. Supported games include favorites such as Monkey Island, Simon the Sorcerer, Space Quest, and many more. To this end, the Virtual Machines (called Engines) are complete reimplementations of each supported game engine in a structured fashion using the C++ language. The development team works either by reverse engineering game executables (usually with the permission of creators of the game), or by using the original source code of the games provided by the creators. The number of engines is constantly growing thanks to a very agile and diversified development team. The VM approach followed by ScummVM results in efficient code, which has been ported to numerous Operating Systems. Besides running on all mainstream desktop environments, namely Windows, Mac OS X and most Unix variants (Linux, *BSD, Solaris), ScummVM works on popular game consoles (Nintendo DS, PlayStation 2, PlayStation Portable and more), smart phones and PDAs (WinCE, PalmOS, iPhone or Symbian based), and even on many not-so-mainstream systems (like BeOS, AmigaOS or OS/2). ScummVM has a highly productive team of about 35 currently active developers (out of an all-time pool of over 60), who work together on a codebase almost 650,000 lines of code. In addition we have many non-developer contributors, and a huge and highly active community. ScummVM is among the top ranking projects hosted on with well over 100,000 monthly downloads and ~10 million project web hits per month.

SilverStripe CMS & Framework

Preferred License: New BSD license

Innovation. Open Source. Make it easier and more fun to build and maintain websites. Change the world. 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.

The Space Telescope Science Institute

Preferred License: New BSD license

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.

Swarm Development Group (SDG)

Preferred License: GNU General Public License (GPL)

The Swarm Development Group (SDG) was founded in September 1999 as a private, not-for-profit [501c(3)] 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++.
