  • GNU Octave

    Science and medicine

    GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable.

  • International Catrobat Association

    Programming languages

    Computational thinking for all with free visual coding apps The Catrobat project develops useful frameworks to create games, animations, or apps easily within a short time. This set of mobile creativity tools for smartphones is inspired by the well-known Scratch framework by the Lifelong Kindergarten Group at the MIT Media Lab. The motivation behind the project is that programming is an important cultural technique on the same level as mathematics and physics, from a practical as well as from a philosophical point of view. Our aim thus is to popularize the skills needed to program from an early age in a fun and engaging way that will facilitate the spread of its adoption among young people all over the world.

  • LibreOffice

    End user applications

    LibreOffice is a modern Free & Open Source Office suite, one of the largest open source projects, and used by millions of users worldwide. LibreOffice is compatible with many file formats like Microsoft® Word, Excel, PowerPoint and Publisher. At its heart though, LibreOffice is built around an open standard, the OpenDocument Format, as its native file format. LibreOffice is developed by users who, just like you, believe in the principles of Free Software and in sharing their work with the world in non-restrictive ways. The development of LibreOffice is supported by The Document Foundation which provides the infrastructure for the project. We believe that users should have the freedom to run, copy, distribute, study, change and improve the software that we distribute. While we do offer no-cost downloads of the LibreOffice suite of programs, Free Software is first and foremost a matter of liberty, not price. We campaign for these freedoms because we believe that everyone deserves them. Though the members of our community hail from many different backgrounds, we all value personal choice and transparency, which translates practically into wider compatibility, more utility, and no end-user lock-in to a single product. We believe that Free Software can provide better-quality, higher-reliability, increased-security, and greater-flexibility than proprietary alternatives. LibreOffice is a large project (approx. 6MLOC), which makes it interestingly complex, but at the same time, provides a place for all sorts of contribution & skills. The community behind LibreOffice is the heart of the project, without which we would not have the resources to continue developing our software. The passion and drive that every individual brings to the community results in collaborative development that often exceeds our own expectations. With tons of different roles in the project, we invite everyone to join us in our work and help us to make LibreOffice known, prosper, and accessible to all.

  • National Resource for Network Biology (NRNB)

    Science and medicine

    The National Resource for Network Biology (NRNB, https://nrnb.org) organizes the development of free, open-source software technologies to enable network-based visualization, analysis, and biomedical discovery. Biomedical research is increasingly dependent on knowledge expressed in terms of networks, including gene, protein and drug interactions, cell-cell and viral-host communication, and vast social networks. Our technologies enable researchers to assemble and analyze these networks and to use them to better understand biological systems and, in particular, how they fail in disease. The NRNB mentoring organization includes projects such as Cytoscape (https://cytoscape.org/), WikiPathways (https://wikipathways.org/), SBML (https://sbml.org/), SBGN (https://sbgn.github.io/) and others. This is a great opportunity to work at the intersection of biology and computing! For example, Cytoscape is downloaded over 24,000 times per month by researchers. We take mentoring seriously and are proud of our 96% success rate (https://nrnb.org/alumni.html#gsoc-tab) with former students and projects. But don’t take our word for it, read testimonials from prior NRNB students (https://nrnb.org/testimonials.html#student-tab) and mentors (https://nrnb.org/testimonials.html#mentor-tab). Find out more about the software projects being developed in coordination with NRNB at our website (https://nrnb.org). Also refer to our GSoC page (https://nrnb.org/gsoc.html) for additional resources and application tips.

    Science and medicine

    OpenAstronomy is a collaboration between open source astronomy, astrophysics & heliophysics projects that are used by researchers and software engineers around the world to study our universe either by analysing the data obtained from amazing instruments like the [James Webb Space telescope](https://jwst.nasa.gov/), the [Square Kilometer Array](https://www.skatelescope.org/) or the [Solar Dynamic Observatory](http://sdo.gsfc.nasa.gov/), developing very sophisticated numerical models (eg., [FLASH](http://flash.uchicago.edu/)) or designing interplanetary trajectories for human-made spacecraft. The analysis of such data helps multiple types of research, from being able to forecast solar storms to detecting planets in other stars, to understanding how galaxies are formed to explain the expansion and the origin of the universe.
