BRL-CAD
Media
This is the place to be if you love computer graphics. We do 2D/3D modeling, 3D printing, solid geometry, design, and more. Depending on the project, you have the opportunity to work with C/C++, Python, OpenGL, OpenCL, Qt, Javascript, and more... Help us develop open source computer-aided technologies (CAx)! We operates as an umbrella organization with several CAx communities including: <ul> <li> - OpenSCAD is a solid 3D modeler with a rich syntax for programmable geometry. <li> - LibreCAD is a 2D modeling system specializing in blueprint-style drawings and draftings. <li> - IfcOpenShell is a library for working with standard IFC building model data. <li> - BRL-CAD is a solid modeling suite with conversion and advanced solid ray tracing features. <li> - Manifold is a solid geometry mesh processing library. </ul> We want to select at least one student for each, so feel free to ask us where to start. <a href="https://opencax.github.io"><img src="https://summerofcode.withgoogle.com/media/org/brl-cad/4ec07aqdfrvygfed-360.png"></a>

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.

checkstyle
Programming languages
Checkstyle is a development tool to help programmers write Java code that is easy to read and adheres to a coding standard. Our utility automates the process of checking Java code to spare humans of this boring (but important) task. This makes it ideal for projects that want to enforce a coding standard. Each and every check also forces our users who are not familiar with these standards to read them and makes them think about why these standards exist.

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.
