Fil-C is a fanatically compatible memory-safe implementation of C and C++. Lots of software compiles and runs with Fil-C with zero or minimal changes. All memory safety errors are caught as Fil-C panics. Fil-C achieves this using a combination of concurrent garbage collection and invisible capabilities (InvisiCaps). Every possibly-unsafe C and C++ operation is checked. Fil-C has no unsafe statement and only limited FFI to unsafe code.

The Astrophysics Source Code Library (ASCL) is a free online registry and repository for source codes of interest to astronomers and astrophysicists, including solar system astronomers, and lists codes that have been used in research that has appeared in, or been submitted to, peer-reviewed publications. The ASCL is indexed by the SAO/NASA Astrophysics Data System (ADS) and Web of Science and is citable by using the unique ascl ID assigned to each code.

Today, we’re looking at two case studies in how to respond when reactionaries appear in your free software community.

Building open-source alternatives to proprietary tools often requires breaking certain assumptions that we hold about how tools ought to be built. It is not enough to make your open-source tools self-hostable, but make them scalable enough so you can offer them yourself for free.
