  • CircuitVerse.org

    Science and medicine

    CircuitVerse is an easy to use digital logic circuit simulator which aims at providing a platform to create, share and learn digital circuits. It can run on almost any device without the need for installing any software. The platform has been designed for use by students, professionals and hobbyists alike. The vision is to develop a community around the platform that will aid students to self-learn digital logic design. The platform is currently used by several universities worldwide. Apart from the simulator, users can create, learn, collaborate and share their work. Teachers can create groups and host assignments on the platform. The platform’s impact has been more evident than ever in the Covid 19 pandemic as CircuitVerse enabled schools and colleges to move their courses online.

  • Free and Open Source Silicon Foundation

    Other

    The FOSSi (Free and Open Source Silicon) Foundation is a not-for-profit organization with the support the growing community of open source silicon hardware. We do this with a variety of activities and through Google Summer of Code we bring together enthusiastic mentees and outstanding projects. Under our umbrella are open source silicon hardware projects, operating systems and compilers for such projects, tools for electronic design automation and the related ecosystem.

  • MDAnalysis

    Science and medicine

    MDAnalysis is a Python library for the analysis of computer simulations of many-body systems at the molecular scale, spanning use cases from interactions of drugs with proteins to novel materials. It is written by scientists for scientists and is used for cutting edge research in biophysics, chemistry, soft-matter physics, and materials research around the world in academia and national research labs. MDAnalysis strives to be highly interoperable and hence a growing number of projects use MDAnalysis as their foundational library or integrate it.

  • The ns-3 Network Simulator Project

    Science and medicine

    Are you interested in contributing to a widely-used performance evaluation tool for computer networking research? ns-3 is a *discrete-event, packet-level network simulator* with an emphasis on networking research and education. Users of ns-3 can construct simulations of computer networks using models of traffic generators, protocols such as TCP/IP, and devices and channels such as Wi-Fi and LTE, and analyze or visualize the results. Simulation plays a vital role in the research and education process, because of the ability for simulations to obtain reproducible results (particularly for wireless protocol design), scale to large networks, and study systems that have not yet been implemented. A particular emphasis in ns-3 is a high degree of realism in the models (including frameworks for using real application and kernel code) and integration of the tool with virtual machine environments and testbeds. Very large scale simulations are possible; simulations of hundreds of millions of nodes have been published. ns-3 has been in development since 2005 and has been making regular releases since June 2008. The simulator is written in C++, with bindings for Python scripting, and uses the CMake build system. We use a GPLv2 licensing model and heavily use mailing lists and Zulip chat, but typically not other social media.
