Thanks to my co-organizers Jana, Laura, @tertsdiepraam.bsky.social and @mara.bsky.social ❤️

Tweede golf in 2025 was… over 80% #opensource!

As a service provider working across the commercial, government, and non-profit sectors, we are extremely proud (and honestly pretty amazed) that 86% of our code written in 2025 was open-source!

Thanks to our clients and funders!

🦀 I've improved the implementation behind all the string formatting macros in Rust: println, panic, format, write, log::info, etc. (Everything using format_args!().) They will compile a bit faster, use a bit less memory while compiling, result in smaller binaries, and produce more efficient code! 🎉
