musl 1.2.6 is now available.
For details see the release announcement on the mailing list: https://www.openwall.com/lists/musl/2026/03/20/1
Source link: https://musl.libc.org/releases/musl-1.2.6.tar.gz
Detailed WHATSNEW: https://git.musl-libc.org/cgit/musl/tree/WHATSNEW?id=v1.2.6#n2444
I tried copilot in VS Code sometime in 2025 and was thoroughly disappointed with its ability. It felt like a really bad auto-complete at best, making plenty of mistakes and generally being utterly irritating to actually use with its need to constantly pop in as I was typing with long form coding suggestions that were often wrong. I was already predisposed to being negative about AI due to the usual mix of reasons and wrote off all the AI coding tools as useless.
What's your favorite AI Coding agent CLI/GUI that can use Codex / Copilot subscriptions?
* Codex is pretty bad from my experience
* Copilot is quite better
* OpenCode I haven't tried recently but I have heard good things.
* Squad, quite good, from a multi-agent perspective, used at work, haven't setup it at home
Any others that you would recommend?
Another old project of mine, Tomlyn, just got a major refresh with the 1.0 release: https://xoofx.github.io/Tomlyn/ - a solid, modern foundation for working with TOML in .NET.
Coding agents made it possible to reach this level of polish in my spare time. It's also pretty liberating to ship it, feel the accomplishment, and move on.

A more honest third party monitor of GitHub services. The vital service has under 92% of uptime for the last three months. Rumor is they are migrating everything to Azure and it is going very badly
Don Knuth, himself, mentioning using Claude Opus 4.6 that helped him resolved a difficult problem. https://cs.stanford.edu/~knuth/papers/claude-cycles.pdf
"I’ll have to revise my opinions about “generative AI” one of these days."
So, is GenAI still generating pure garbage, Knuth an idiot, that likely doesn't know what is he doing? 🤔
Just released a major 3.0 version of SharpYaml https://xoofx.github.io/SharpYaml/ 🎉
Back from maintenance mode, this new version brings significant improvements: Compatibility with System.Text.Json attributes, NativeAOT support built-in, more built-in serializable types supported, faster than ever and full documentation website! 🚀
I had a need for NativeAOT support for a new project, here it is!

Quite surprising release from the french administration today:

Dunno if this is the first MCP server released officially by a country, but nonetheless, this is a great move.
