We are developers of the Audacity® sound editor which runs on Linux, Windows, and Mac. Audacity is widely used, with around 15 million downloads in the past year from Sourceforge ( Audacity won Best Project for Multimedia in the Sourceforge 2007 Community Choice Awards ( Audacity has been featured widely in the media, including (, and a reference in a New York Times article. Audacity is a flagship application of the wxWidgets ( cross-platform toolkit and it is widely admired as one of the only multimedia applications that runs beautifully on all three major platforms. Care has been taken to make Audacity work with screen readers for visually impaired users. Audacity has been translated into almost 30 languages, and nearly half of Audacity users use it in a language other than English. Perhaps most importantly, Audacity has a large and vibrant developer community. There are no full-time developers, but about a dozen team members who have been with the project for several years act as the leaders of the community, setting the direction and coordinating releases, but many contributions come from the dozens of other developers who have contributed small features, bug fixes, or other patches, and hundreds of other developers who participate on the mailing lists and help test and track down bugs. In addition, dozens of volunteers help with documentation, technical support, language translation, community support, and more.

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

BRL-CAD is represented and developed by a consortium of individuals in the open source community from industry, academia, government, and private industry from all over the world. Our organizational interests in BRL-CAD vary across the project's primary focus areas including computer-aided design (CAD), computer-aided manufacturing (CAM), solid modeling, and computer graphics. We have about a half-dozen core developers that are active on a daily basis with the project and several dozen community contributors, modelers, artists, and engineers. Our developers predominantly interact over IRC and through our various mailing lists. The BRL-CAD package is a powerful cross-platform open source solid modeling system that includes interactive solid geometry editing, ray-tracing support for rendering and geometric analysis, image and signal-processing tools, system performance analysis tools, a robust high-performance geometry engine, and much more. Currently standing at more than a million lines of code, 400 utilities, and hundreds of man-hours investment, BRL-CAD has more than 20 years of development history (since 1979) and is in production use by more than 2000 organizations around the world (this was our last statistic before we went open source and became untraceable). As useless bragging rights and fun statistics, the Ohloh source code statistics site recognized BRL-CAD as having "the world's oldest source code repository". Ohloh is a site that tracks the commit activity for more than 12,000 open source repositories performing in-depth historical analyses and commit tracking. When they reviewed the project histories for all projects in their database, BRL-CAD came in as the oldest project that has had continuous uninterrupted activity even edging out Emacs and GCC: Released as open source software just a little over three years ago, BRL-CAD has received considerable attention from the CAD and solid modeling communities. We've had more than 230K downloads within last 12 months alone and our download rate is increasing. As far as we're aware, BRL-CAD is actually the only open source solid modeling system available with production-quality capabilities under an OSI-approved license. The BRL-CAD user-base is primarily composed of individuals in the CAD industry where the modeling requirements are fundamentally different to those of content modelers (e.g., Blender) that are used for animation, gaming, and film purposes. Where content modelers include commercial products like Maya, Softimage, and 3D Studio; BRL-CAD's primary competitors are in an entirely separate industry where commercial products like Unigraphics, Solidworks, Pro/Engineer, CATIA, and AutoCAD dominate. See for a visual overview of where BRL-CAD fits within the various CAD industries. Our goal is to become the best solid modeling system available by encouraging collaboration throughout the CAD communities, improving recognition that we're a production-quality F/OSS project, providing effective/better user-friendly tools, and by continuing to work hard at implementing the features needed by our users.

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.

The Enlightenment Project

Preferred License: New BSD license

The Enlightenment Project is an open source project dedicated to providing advanced graphical libraries, tools, and environments. Currently, the project is made up of three different components: Enlightenment DR16, Enlightenment DR17, and the Enlightenment Foundation Libraries. While we are best known for the Enlightenment Window Manager itself, there is a long history of providing advanced libraries and tools to support the window manager and other applications, such as Imlib, Imlib2, and FnLib, which extend far beyond the window manager itself in scope. Presently, in development towards the DR17 Desktop Shell, we have created an entirely new set of libraries and tools that provide more power and flexibility than any other group of graphical libraries available: the Enlightenment Foundation Libraries. These libraries offer such functionality as an X11 canvas library (Evas), X11 abstraction layer (Ecore), and an canvas based interface layout library (Edje) that allows separation of interface and application logic (thus making every application that uses it "skinable"). These libraries are extremely fast and lightweight. So much so they have been adopted by many other organizations. Most notably, organizations such as Openmoko, Maemo, Terrasoft, the Canola project, and more.

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.

GIMP - GNU Image Manipulation Program

Preferred License: GNU General Public License (GPL)

GIMP is an acronym for GNU Image Manipulation Program. At over ten years old, its history merges itself with the development of a Free Desktop Environment, having first provided the basis for projects such as gtk+, gutemprint and other graphic programs. It is a free program distributed under the GPLv2 suitable for such tasks as photo retouching, image composition and image authoring. It is usually pre-installed in all major Desktop GNU/Linux distributions and available in other Platforms such as Microsoft's Windows. GIMP is a Free Software, high-end photo manipulation application that supports creating original art from images; a high-end application for producing icons, graphical elements of web pages and art for user interface elements and also works as a platform for programming cutting-edge image processing algorithms, by scientists and artists. With the advent and spreading of digital pictures and imagery, being able to edit and change photos in a computer became a major task on the daily usage of personal computers. Everyone having at home tools far more powerful than those available to professional photographers for decades. Most pictures hardware do offer a gratis program with basic picture manipulation facilities - but one of the main purposes of Free Software is exactly to end the artificial restrictions of features and capabilities of any software. Therefore, GIMP provides a fully featured image manipulation environment available for everyone, and we have a goal of making it each time richer. Currently, GIMP is undergoing a deep change in its rendering core, which is being replaced by the Generic Graphics Library - GEGL. GEGL while being developed by members of the GIMP team and community and is also a modular and independent graph based image processing framework, with bindings to other languages. It aims to provide GIMP with a lot of currently missing high-end features such as non-destructive editing, deep color depth support, HDR, and macro recording.

The Globus Alliance

Preferred License: Apache License, 2.0

The Globus Alliance ( is a community of organizations and individuals developing fundamental technologies behind the "Grid," which lets people share computing power, databases, instruments, and other on-line tools securely across corporate, institutional, and geographic boundaries without sacrificing local autonomy. Since its creation in 1996, the Globus Alliance has been committed to developing open source software, although development was initially carried out by a small number of university research groups. However, since transitioning in 2005 to an open governance model (, derived from Apache's Jakarta project, the scope of participants has widened to include many more groups around the world, including companies and individuals. Globus currently hosts more than 20 projects, actively developed by a community of more than 100 committers, and spanning a variety of technology concerns on grid systems: common runtime, data management, information management, security, and documentation. Additionally, members of the Globus community can propose new projects which, after an "incubation" process ( can escalate to full Globus projects. There are currently more than 25 projects in incubation.

Project Hackystat

Preferred License: Apache License, 2.0

The mission of Project Hackystat is to provide a framework for collection, analysis, visualization, interpretation, annotation, and dissemination of software development process and product data. Work on Hackystat began in 2001 as a research activity in the Collaborative Software Developmnt Laboratory ( in the Department of Information and Computer Sciences ( at the University of Hawaii ( From 2001 to 2006, the project grew a substantial code base (approximately 350,000 LOC), user community (over 800 users of the "public" Version 7 Hackystat server, with an undetermined additional number of users on private servers), and developers (dozens of contributors to the code base from approximately 20 academic and industry sites). A significant number of publications occurred during this time (a partial list of which is available at In addition, there was one commercial, non-open source spin-off based upon a subset of this project called Sixth Sense Analytics ( A summary of Project Hackystat's release history is available at In 2007, we made the decision to reimplement the code base almost entirely from scratch as a coordinated set of RESTful web services. This effort took nine months, and Version 8 has been in public release since January, 2008. We also decided to move the hosting of the project from the University of Hawaii to Google Project Hosting. The old site is still available at, although it is no longer maintained.

GNU Hurd

Preferred License: GNU General Public License (GPL)

The Hurd project is a loose community of people sharing a common interest in developing the Hurd kernel, which is the official kernel of the GNU operating system (see ). When the Hurd was originally started in 1990, it was the last missing major component for a complete GNU system. Today Linux and other free kernels are available to fill this gap, and the combination of GNU and Linux (often incorrectly called just "Linux", see ) is in wide use. However, the Hurd is still interesting due to its unique design, better fitting the GNU philosophy than traditional monolithic kernels like Linux. The GNU GPL guarantees that all users of software published under this license get the legal permission to adapt the software they are using according to their wishes, and also get the source code and other tools necessary to put this permission to use. However, in traditional operating systems, the kernel and related low-level system software are protected from normal users, and cannot be easily modified; only the system administrator has power over these. The Hurd offers special mechanisms that allow any user to change almost all of the system functionality he uses, without affecting the rest of the system, and thus easily (at runtime) and without any special permissions. This ability to run subenvironments more or less independant from the rest of the system, can be classified as a very sophisticated lightweight virtualization approach. (See ) To offer these possibilities, the Hurd uses a true multiserver microkernel architecture. That makes it quite unique: The Hurd is the only general-purpose multiserver microkernel system in development today that is nearly ready for everyday use, and offering almost perfect UNIX compatibility. (More than half of the packages in the Debian repository are available for the Hurd.) All other existing true microkernel systems are either research projects not nearly complete enough for actual use, or limited to embedded systems and other special purposes, or both. Marcus Brinkmann and Neal Walfield from the Hurd project are working at the bleeding edge of microkernel operating system research. They have been in contact with the most distinguished researchers in that field from the L4 ( ) and EROS ( ) / Coyotos ( ) microkernel operating system groups, and have written a couple of research papers ( ).

Computer Systems Research Group, Vrije Universiteit (MINIX)

Preferred License: New BSD license

MINIX 3 is a small, modular, multiserver operating system aimed at being highly reliable, fault tolerant and self healing. Only about 5000 lines of code run in kernel mode. The rest runs as a collection of user processes, mostly separate processes for each device driver and server. If a driver fails, it is automatically replaced by a fresh copy, without user intervention (or even knowledge) and without affecting running programs. Few other systems can survive fatal errors in some critical system components without even missing a beat. The goal of reliable systems will have been achieved when no computer has a RESET button and no user has ever experienced a crash and does not know anyone personally who has ever experienced a crash. MINIX 3 supports the POSIX interface and about 500 of the standard UNIX programs have been ported to it, including X11, gcc, perl, python, ghostview, mplayer, the GNU core utilities, and many more. There is also a a simple GUI (EDE). Nevertheless there is much more to do. You can help.

NCSA - The National Center for Supercomputing Applications at the University of Illinois

Preferred License: Apache License, 2.0

The University of Illinois' National Center for Supercomputing Applications (NCSA), one of the five original centers in the National Science Foundation's Supercomputer Centers Program, opened its doors in January 1986. Since then, NCSA has contributed significantly to the birth and growth of the worldwide cyberinfrastructure for science and engineering, operating some of the world's most powerful supercomputers and developing the software needed to efficiently use these systems (for example, NCSA Telnet and, in 1993, NCSA Mosaic™, the first readily available graphical Web browser). Today the center is recognized as an international leader in deploying robust high-performance computing resources and in working with research communities to develop new computing and software technologies. The center focuses on: Developing and deploying powerful, reliable computing, data, and networking resources that enable researchers to solve the most demanding science and engineering problems in a timely manner. We develop and explore innovative architectures and techniques to achieve petascale science. Working with research communities to develop the tailored cyberenvironments that provide the means to fully exploit the extraordinary resources available on the Internet (computing systems, data sources and stores, and tools). Researching and developing software, techniques, and tools to improve national cybersecurity and to help law enforcement better respond to cyberattacks. Providing insights into complex systems and sharing the thrill of scientific discovery with the broadest possible audience through artful visualizations of scientific phenomena. Preparing the next generation of scientists and engineers to effectively use the growing national cyberinfrastructure. The National Science Foundation, the state of Illinois, the University of Illinois, industrial partners, and other federal agencies support NCSA. Cyberenvironments and Technologies Division All the hammers and all the nails in the world can't build a house; tools alone just aren't enough to get the job done. It's the same in the world of cyberscience. The advantages of the national cyberinfrastructure won't be realized without scientists and engineers who are empowered to tap its capabilities. To that end, NCSA is developing cyber¬environments that will enable scientists and engineers to take full advantage of the nation's cyber-resources to drive scientific and engineering advances. Cyberenvironments will integrate distributed computing and data resources into end-to-end scientific processes, providing a boost in productivity. Cyberenvironments include scientific and engineering applications, graphical user interfaces and portals for easy interaction with the applications, and workflow and collaboration software, as well as an integrated data analysis and visualization capability. They couple traditional desktop scientific and engineering applications with national and global cyber-resources to provide researchers an unprecedented capability to assemble, integrate, automate, and manage complex, collaborative projects. Cyberenvironments will ensure that the capabilities in the national cyberinfrastructure can be brought to bear on the most challenging science and engineering issues facing the nation and the world.

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.

This project is truly amazing, which attracts a variety of people from around the globe. We are students, researchers, interaction designers, user interface designers, software engineers working on opens source hardware and software solutions. With over 1300 NUI Group members all over the world we are changing ways of human computer interaction. One very important aspect of this project is to create and utilize open standards that allows software development to flourish. For example, we use the TUIO protocol, which is the standard for tabletop communication. Another crucial standard that must be created in an open environment is "Gesture Standards", which allows for fluid interaction across input devices. Our doors are always open and looking for new people with similar interests and dreams. We believe that community is more powerful than money or technology. We are mainly maintaining a set of open source projects including: OpenTouch - WinLibre GSoC 2007 Best Success - multi-touch library for Mac OS X Touchlib - First open source library for multi-touch screen operation working under Linux and Windows TouchAPI- A library which allows for rapid prototyping of multi-touch client applications in Adobe Flash/Flex/AIR or Silverlight/WPF TUIO Simulator - Java TUIO protocol simulator allowing you to test your multitouch apps without multitouch screen (written by reactivision project team) Other than just mentioned projects, we are also looking forward to work with other open source projects like reactivision, libavg, opentable and many more that are widely used by NUI Group members. We have also started to work on multitouch applications for iPhone/iPod Touch using recently released iPhone SDK and we are waiting for innovative project proposals from community.

Open64 is the final result of research contributions from a number of compiler groups around the world. Formerly known as Pro64, Open64 was initially created by SGI and licensed under the GNU Public License (GPL). It was derived from SGI's MIPSPro compiler. Open64 also derives from work done by Intel Corp, in conjunction with the Chinese Academy of Sciences. They created the Open Research Compiler (ORC), a specially modified version of Open64 with custom modifications for researchers. These changes were later folded back into the main Open64 source tree in 2005. Open64 has been retargetted to a number of architectures. Pathscale modified Open64 to create EkoPath, a compiler for the AMD64 architecture. The University of Delaware's Computer Architecture and Parallel Systems Laboratory (CAPSL) modified Open64 to create the Kylin Compiler, a compiler for Intel's X-Scale architecture. CAPSL and Hewlett-Packard are currently working on Osprey, a project to replace Open64's front end (derived from GCC 2.95's frontend) with the current GCC front end. The Open64 compiler suite currently includes compilers for C, C++, and Fortran90/95 compilers for the IA-64 Linux ABI and API standards. Open64 is currently in version 4.1. Professor Guang Gao and CAPSL at the University of Delaware are the current gatekeepers of the project.

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).

Pardus project

Preferred License: GNU General Public License (GPL)

The participating organization is the Pardus project ( Pardus is a Linux distribution development project under the auspices of TUBITAK UEKAE. TUBITAK (The National Scientific and Technological Research Council of Turkey) UEKAE (National Research Institute for Electronic and Cryptography) is a government-run research institute in Turkey. TUBITAK ( is the scientific research funding organization of Turkey - a la NSF, and UEKAE is one of the research institutes of TUBITAK - a la Max Planck. TUBITAK UEKAE is located in Gebze, ca. 50 km from Istanbul, and has offices in Ankara as well. TUBITAK UEKAE has more than 500 researchers working in the fields of information security and cryptography. Pardus project has a triad of goals: Developing Linux distribution for widespread use in Turkey and elsewhere, to have some sound financial sustainability even though the mother organization is a not-for-profit, and finally to develop a FOSS ecosystem in Turkey and elsewhere to innovate in Linux and related technologies. Pardus, the distribution, is the main tool to achieve these goals, and has, in turn, three fundamental requirements: Having full Turkish (i.e. mostly UTF-8) support, ease of use and installation, and a human-centric and task-based design approach (instead of a technology-centric and tool-based one). Pardus project has been launched in Fall 2003 and the technical roadmap has been laid of in Fall 2004. The Pardus developers consist of 15 TUBITAK UEKAE employed core developers (10 full-time) and more than 25 community developers. The product of the project, Pardus, is a free operating system, main pieces of which (and all the code developed within the Pardus project) are distributed under GPL license.

The Java PathFinder Team

Preferred License: NASA Open Source Agreement 1.3

The Java PathFinder project (JPF) was started at NASA Ames Research Center in 1999. JPF is a research JVM (implemented in Java) that runs as a "software model checker"; It stores program states and checks properties, backtracking and re-scheduling threads as necessary to cover all program executions. JPF has won several awards, inside and outside of NASA. JPF was open sourced in April 2005 with the mainline development hosted on Sourceforge. The primary goal of open sourcing JPF was to enable students to contribute and take their code with them after their summer internships - and begin to build a development community. So far, we have received contributions from students at SUNY Stonybrook, Kansas State, MIT, CMU, U. Mass, Georgia Tech, UC Santa Barbara, University of Nebraska, INRIA, Toronto, Masaryk University and UIUC. The primary industrial user of JPF is Fujitsu Labs. The Java PathFinder Team is comprised of the JPF research team at NASA Ames, several past NASA team members who have moved to industry, and a number of students who are using JPF in their graduate studies.

Zikula Application Framework

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

Zikula is an Open Source Web Application Framework written in the popular web scripting language PHP. It is free to download and use, and is supported by a large community of many thousands of people across the globe. There are over 500,000 websites using the Zikula Framework on the web today. The Zikula Software Foundation was established in 2005 to ensure the longevity of the project, and is a non profit organization that assists the project in its long term strategic goals. The members of the Foundation's board are all volunteers and members of the project. Zikula itself is managed day to day by a five person steering committee, elected by the members of the Software Foundation. The core code is developed by around twenty developers, though there are many other regular contributors who submit patches and changes both small and large to the core code and these are often incorporated into the next release. The project’s biggest advantage is the mass of third party developments available. Much like other web application frameworks, the project lives and dies by the third party developments which are available, and these are hundreds for Zikula, from basic content modules to forums and download management scripts. These range from the complicated to the simplistic, and the system can be customized to an individual user’s need depending on the type of website they are trying to create.

We are the open source development team at Portland State University. We develop a lot of different kinds of open source project: everything from the world's most advanced low-cost amateur rockets and law-enforcement communication systems to web toolkits and programming environments. We specialize in open source projects with an academic component, and those that are off the beaten path. We think we've been an academic leader in the R&D side of free and open source software. For example, the components of the X Window System developed by PSU students, faculty and friends touch users of the free desktop every day. Our location in Portland, Oregon gives us access to a large pool of top-quality open source developers, and they have been very good to us in helping to mentor our students. For Summer of Code, we are looking for developers in Portland and from around the globe who are excited about an open source project that has an academic bent, or that doesn't fit well with any other Summer of Code organization.

Ptolemy Project, University of California, Berkeley

Preferred License: New BSD license

The Ptolemy project studies modeling, simulation, and design of concurrent, real-time, embedded systems. The focus is on assembly of concurrent components. The key underlying principle in the project is the use of well-defined models of computation that govern the interaction between components. A major problem area being addressed is the use of heterogeneous mixtures of models of computation. A software system called Ptolemy II is being constructed in Java. Ptolemy II differs from other commonly used graphical block-diagram languages in that they typically support only one model of computation. In addition, Ptolemy II is a more open architecture in that its infrastructure is open source, and the interfaces to the core mechanisms in the software are published and documented. The Ptolemy project has been under development in Java since 1997.The work is conducted in the Department of Electrical Engineering and Computer Sciences of the University of California at Berkeley. Currently, full-time members of the project include 1 faculty member, 3 systems/software managers, 5 postdoctoral/visiting scholars, 11 grad students, 2 visitors, 2 undergrad students (details at ). Our contributors include people from industry, universities, research institutions and other public projects (details at ). We have a long collaboration with the Kepler project (, an open-source scientific workflow system that uses Ptolemy as its core.

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.

"OpenStreetMap is a project aimed squarely at creating and providing free geographic data such as street maps to anyone who wants them. The project was started because most maps you think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive or unexpected ways." Contributors to OpenStreetMap take handheld GPS devices with them on journeys, or go out specially to record GPS tracks. They record street names, village names and other features using notebooks, digital cameras, and voice-recorders. Back at the computer, contributors upload those GPS logs showing where they travelled, and trace-out the roads on OpenStreetMap's collaborative database. Using their notes, contributors add the street names, information such as the type of road or path, and the connections between roads. That data is then processed to produce detailed street-level maps, which can be published freely on sites such as Wikipedia, used to create handheld or in-car navigation devices, or printed and copied without restriction.

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++.

Translate Toolkit & Pootle

Preferred License: GNU General Public License (GPL)

We are focused on the development of localization tools. The focus of the tools is to make localization of computer software and content translation easier and of higher quality. We do this by creating the Translate Toolkit (a set of tools to manipulate translation formats e.g. we transform Mozilla and localizations into Gettext PO) and Pootle (an online translation and translation management tools used by and Creative Commons amongst many others). We also create an online resource to help others localize effectively, especially in minority languages. The people involved in our project are closely aligned with translation and localization. Thus we are not programmers theorizing about what is best for localizers but are localizers actively trying to make our lives easier and to improve the quality of our own translations.

TurboGears is an open source project which was founded by Kevin Dangoor in 2005. Kevin brought together a number of tools which people were using for web development into one usable package, in a few hundred lines of code. The result was a framework which allowed for swappable components, allowing a developer the flexibility to choose the best-of-breed technology to solve their web application challenges. As the popularity of TurboGears grew, more developers began to participate. The development of TurboGears became a world-wide effort. Though our developer base has changed throughout the project's life, our ultimate goal has remained: To provide web developers a toolkit which is easy to get started with, supports agile development and provides an exceedingly high level of flexibility, unmatched in the world of web frameworks. Currently our development staff consists of about a dozen programmers (though this figure might be a little bit misleading since there are dozens more developers working on core dependencies, from Genshi and SQLAlchemy to ToscaWidgets, and DBSprockets) whose efforts are divided between supporting a stable base and developing the next generation of our software. This has resulted in merging our efforts with those of another popular Python web framework (Pylons) with the goal to build an even more component-oriented framework and to perpetuate our active role in the Python web frameworks domain. TurboGears, strives to bring together the open source community to develop cutting-edge technology which is enjoyable to use.

WinLibre project is an open source project aimed at popularizing Open Source software. WinLibre is a META-project that was originally targeted for the windows platform (hence its name) but it has evolved during the last 2 years to embrace also the Mac OS and Linux platforms. We are focusing on delivering to our users quality open source software with a strong emphasis on ease of use. We are mainly maintaining WinLibre (open source software distribution for windows) and MacLibre (open source software distribution for Mac OS X). The Winlibre distribution provides a collection of first-class open-source software bundled in a easy single installer & updater. Through time and thanks to the former editions of the Google Summer Of Code, the Winlibre project has evolved and created other sub-projects to fill gaps in the open-source desktop software offering. The Maclibre distribution is an equivalent to the Winlibre distribution for Mac OS.

Preferred License: New BSD license

Xiph.Org 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 developed most of the major patent-free audio and video codecs currently in use, including Vorbis, Speex, FLAC and Theora, as well as developing 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, browser plugins and convenience libraries to facilitate adoption of Xiph.Org's lower-level technology. As such the two projects have largely aligned goals, but focus on different levels in the stack.

XMMS2 - X(cross)platform Music Multiplexing System

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

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 Rundström and Anders Waldenborg 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).
