Holiday chaos? Ran out of time for your talk proposal? We're extending the deadline to submit talks to our CFP by 2 weeks. It's now open until January 18th! Submit your talk now at 2026.rustweek.org#cfp. Happy holidays from us at RustWeek!

Second blog post from the Rust vision doc effort: blog.rust-lang.org/2025/12/19/w... Working through the data we gathered really helped sharpen my understanding here.

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! (1/3)

New release of sudo-rs! Version 0.2.11 is out with askpass and multi-lingual support. Want to see sudo-rs in your language? You can start helping out today. PR's are welcome! We thank the @sovereign.tech for investing in this work, as well as 15 external contributors! github.com/trifectatech...

The joint statement “Improving Europe's cybersecurity posture through memory safety”, has now been published: trifectatech.org/blog/calling... It calls for stronger #MemorySafety incentives in EU cybersecurity policies. Thanks to all supporters and contributors! #security

How do you test code that a CI machine won't run? To support avx-512 SIMD instructions in zlib-rs, we taught Miri how to emulate them. trifectatech.org/blog/emulati... #rustlang

How do Merkle Tree Certificates help against the threat of Quantum computers to internet security? Maximilian Pohl explains MTCs, discusses his experience implementing an early @ietf.org draft, and @cloudflare.social's and Google Security's current experiments.

Canonical's Jon Seager talks about our sudo-rs and ntpd-rs (!) in ubuntu-ls.bsky.social, and his bold but level-headed vision on Rust's future for Ubuntu, in the Rust in Production podcast with Matthias Endler: corrode.dev/podcast/s05e... #rustlang #ubuntu @canonicalltd.bsky.social @jnsgr.uk

How about Rust for real-time applications? @diondokter.nl gets you started: buff.ly/g8qruby #rustlang #embedded

Early Bird tickets for RustWeek 2026 are available until Nov 30. Get your 20% discount while you can! The world's biggest Rust conference returns to beautiful Utrecht, welcoming over 900+ community members, professionals and the maintainers of Rust. 2026.rustweek.org #rustweek2026 #rustlang

🦀 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! 🎉

Please support the call for Memory Safety incentives in EU cybersecurity policies. If you agree with the position that memory safety should be on the EU and national cybersecurity agendas, please consider adding your name to this statement to show your support: trifectatech.org/blog/support... 1/3

Openleadr-rs is an opinionated, open-source Rust implementation of the OpenADR 3.0 protocol - and it's ready for real-world pilots. Interested? Check out the repo here: buff.ly/sgwLs6u

** Major milestone ** our sudo-rs is the default sudo for the upcoming Ubuntu 🚀 🦀 More on the Ubuntu blog: discourse.ubuntu.com/t/sudo-rs-is... #rust #rustlang

We have 100+ Rust-related articles on our blog! Read them here: tweedegolf.nl/en/blog/rust Topics: web development, systems programming, Embedded Rust, open-source projects, memory-safety, interoperability with other languages, testing and bug hunting.. and much more. Enjoy! #rustlang

I’ve been maintaining the Rust flamegraph implementation for three years, releasing about every 3 months on average. Consider sponsoring my work if it’s been valuable to you(r team).

Ruben and David are the champions (how cool is that?) for the NTS Pool session at the @ietf.org 123 Hackathon! In parallel they will also work on NTPv5 interop testing and Network Time Security for PTP and CSPTP. wiki.ietf.org/en/meeting/1... #ietf123

Earlier this week, we as #RustWeek organizers came together for a dinner party to celebrate the success of RustWeek 2025 and make the first plans for 2026! What would you like to see at #RustWeek2026? What should we keep the same and what should we change?✨ Excited to see you all again next year.💛

bzip2 - now in Rust 🦀 A couple of cool things here: 1) we used c2rust, and it worked! 2) Alex transferred the bzip2 crate to us during the project 3) the funding was provided, via NLnet Foundation, by the Dutch Ministry of the Interior! (and "Koninkrijksrelaties", look it up :))

We just published all talks from RustWeek 2025 🦀 🌎 Clear your calendars: 25+ hours and 54 talks worth of amazing Rust content! www.youtube.com/playlist?lis... #rustlang #rust #RustWeek

We prefer to say "we'd love to be in your distro". Nevertheless, a really good "sudo-rs explained" by @brodierobertson.xyz‬. Thanks! www.youtube.com/watch?v=Le4i...

Part 2: "with SIMD clever programmers can still beat the compiler"

On my way back home after RustWeek 2025. So, so proud that we hosted the Rust Project All-Hands, the 10 years of Rust celebration, and the biggest Rust conference yet. See you all next year! Thanks to my co-organizers Jana, Laura, @tertsdiepraam.bsky.social and @mara.bsky.social ❤️ #rustlang #rust

Trifecta Tech Foundation is now a member of the @rustfoundation.org ! Why? We believe that software must become safer; that this is paramount in critical infrastructure; and that #rustlang is an outstanding choice of technology for this purpose. rustfoundation.org/media/rust-f...
