  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.

  UC OSPO

  Science and medicine

  The UCSC Open Source Program Office (OSPO) and the UC OSPO Network supports open source work throughout the University of California system. Beginning in 2022, the UCSC OSPO took over the programmatic responsibilities of the UCSC Center for Research in Open Source Software (CROSS), including mentorship activities such as GSoC. The UCSC OSPO creates partnerships with stakeholders within and outside the UC system in order to help students learn from open source communities, support scientists in using open source to accelerate research efforts, and connect students and scientists with sponsors from industry, government, and foundations. The OSPO helps bridge the gap between academic research and successful open source projects by promoting innovative projects maintained by UC-affiliated scientists and researchers. We support the transfer of cutting-edge technology resulting from UC-originating research to industry via successful open source projects. Due to the multi-campus nature of our current efforts, the projects we support and promote cover a wide range of topics and technologies - including:
