The GNU C Library version 2.41 is now available.

The GNU C Library is used as the C library in the GNU system and in GNU/Linux systems, as well as many other systems that use Linux as the kernel.

The GNU C Library is primarily designed to be a portable and high performance C library. It follows all relevant standards including ISO C23 and POSIX.1-2024. It is also internationalized and has one of the most complete internationalization interfaces known.

I wrote a program that turns the feed it receives from your webcam in ASCII art. It's open source: you can find the code on Github.

Forgejo is a self-hosted lightweight software forge. In version 10.0: TOTP secrets were made more secure. The UI was made more accessible and reworked to improve the UX. Searching users, repositories, releases and issues was improved. Low German (Plattdüütsch) translation was completed. This is the last version to allow a transparent upgrade from Gitea v1.22 or lower.
