I'll take a side of the four freedoms with that. ❤️

The GNU C Library version 2.44 is now available! New features include system-wide tunables, memory mapping optimization using transparent huge pages, more optimized and correctly rounded mathematical functions, vectorization for AArch64 and RISC-V, Guarded Control Stack locking on AArch64, support for LoongArch32, and more...

How C++20 improved the for-loop syntax lzon.ca/posts/tips/cpp…

We need a strong, vibrant FOSS ecosystem to keep the future democratic. Let's keep creating, contributing, and collaborating in the open. The future gets more interesting when everyone has the freedom to build it.

This openness creates more than code; it creates agency. It empowers students to learn, researchers to validate science, and startups to compete without gatekeepers. As technology evolves, questions of security and governance deserve thoughtful, transparent answers.

True FOSS (Free and Open Source Software) is built on four essential pillars: 🔓 Freedom to Run for any purpose. 🔍 Freedom to Study & change the source code. 🤝 Freedom to Share & help your neighbor. 🚀 Freedom to Improve & share those modifications with the world.

The next generation of technology should have more people shaping it, not fewer. The GNU Toolchain exists to guarantee Software Freedom—ensuring you have the rights to run, study, share, and improve the tech we all rely on. 🧵👇

@derjanni @sovtechagency @bundeskanzler @derjanni GNU Toolchain ≠ GNU Project. GNU Toolchain didn't fund libmicrohttpd — that's Sovereign Tech Agency money for a separate GNU lib. Different teams, different goals. Not every GNU package is a toolchain component. #readingIsFundamental

I browsed through the @sovtechagency project pages, and the @gnutools funding of libmicrohttpd3 with €234K of my tax money raised eyebrows. I know the lib and use it regularly, v2 is still experimental. But @bundeskanzler already paid for v3? #wtf
