A colourful box that says: New blog post! Callgraph Analysis Writing custom lints for fun and profit! Compiler team lead Jynn Nelson dives into the world of static analysis and callgraphs by showing how Ferrocene ensures that only the most strictly tested code is used in safety-critical applications. Thank you for reading and following us on BlueSky.

Some fun compiler-adjacent #RustLang reading: How can you make sure [panic!] is unreachable in part of your program? This write-up goes into how we approached callgraph analysis in #Ferrocene – and how you can try it out for yourself!

A colorful square with tones of blue, green, purple and red. In the top left corner is the Ferrous Systems logo. What follows is a green box and it says "New release". This is the header of a light blue box. Inside this box, the headline reads: Ferrocene 26.02.0 is here: Rust for safety-critical systems just got easier with ASIL B certification for the Rust [core] library. Read the blog and release notes now! The post is so colorful because we are excited and happy about this news and thank you for taking the time to see our content. We appreciate it!

Ferrocene 26.02.0 is out 🦀

This release adds ISO 262626 (ASIL B) cert for a subset of #RustLang [core], making it easier to start building certifiable Rust for safety-critical systems.

At #ew26? come by booth 4-402 (and get some stickers!).

A blue square that advertises the latest white paper from Ferrous Systems titled The Business case for Rust & Ferrocene. Description on the square says: With growing software complexity and stricter regulatory requirements, traditional programming languages struggle to meet the demands of modern, safety-critical embedded systems. Read how Rust and the Ferrocene toolchain deliver a safer, more efficient approach — blending performance, memory safety, open source flexibility, and certification readiness.

Why Rust? Because it makes commercial sense. If you're unsure if #RustLang is right for your business – or want to convince your CTO that it's time to add Rust to your stack, then it's time to download our white paper:
