  cBioPortal for Cancer Genomics

  Science and medicine

  The cBioPortal for Cancer Genomics is a resource designed to provide broad community access to cancer genomic data. It provides a unique user­-friendly and "biology­-centric computational user interface", with the goal of making genomic data more easily accessible to translational scientists, biologists, and clinicians. The interface was explicitly built and continues to evolve with careful usability studies involving multiple biological and clinical users, and an active and engaged user base.

  Cuneiform Digital Library Initiative (CDLI)

  Science and medicine

  The Cuneiform Digital Library Initiative (CDLI) is a global collaboration of Assyriologists, museum curators, and historians working together to make the world’s earliest written records accessible online. CDLI focuses on cuneiform inscriptions dating back to the very beginning of writing around 3350 BC. Today, more than 500,000 such artifacts are held in museums and private collections worldwide, and CDLI has already digitally catalogued over 350,000 of them, helping researchers and the public explore humanity’s oldest written heritage.

  Kornia

  Programming languages

  Kornia AI is a non-profit organization advancing Spatial Artificial Intelligence through open collaboration. Founded in 2018 and registered as a non-profit in 2023, Kornia AI is supported by a global contributor community. The organization began with Kornia, a widely adopted Python library for Differentiable Computer Vision (>2M downloads/month, 400+ Google Scholar citations). In recent years, the core maintainers have shifted focus to kornia-rs, a native Rust stack for high‑performance 3D computer vision and spatial AI. Our direction emphasizes robotics and edge deployment: safe, memory‑efficient, low‑latency pipelines that run on constrained devices (e.g., embedded/Jetson‑class hardware). kornia-rs is gaining traction in the open-source community and is used by leading companies such as Farm-ng, Rerun.io, and Copper Robotics, who have featured the project on their platforms.
