Our Rust workshops are hands-on: you’ll mostly write code. We have workshops for every stage of your journey, from the basics to async, testing, embedded, and C-to-Rust migration, for individuals and teams, remote or on-site. We’re an accredited Rust Foundation Trusted Training provider. #rustlang

Our @paolo.ricciuti.me is speaking at this year’s Svelte Summit with @sveltesociety.dev, happening Nov 19-20. The day before, on Nov 18, Paolo will hold a workshop about agentic engineering with Svelte. Tickets are on sale now. See you in Ljubljana! 👋 👉 sveltesummit.com #Svelte

. @mainmatter.com has a need for a Europe-based #reactnative engineer, ideally German or Italian-speaking. Anyone?

Do you want to build practical Rust skills? Join our upcoming workshop in Barcelona! We’re running a "Learn Rust from Scratch" workshop at Upskilling Week on Thu, Nov 19. The hands-on workshop covers ownership and borrowing, the standard library, async & testing. Register below 👇 #RustLang

Thanks everyone for a great EuroRust! See you next year in Prague 🙌 #RustLang #EuroRust27

That's a wrap on the first day of EuroRust. Thanks everyone for a great day, see you tomorrow! 🙌

All code will converge on Rust @marcoow.bsky.social explains why when the cost of building systems in Rust goes down and the end result remains superior to what other stacks produce, all code that *can* be Rust will eventually *be* Rust. → mainmatter.com/blog/2026/10... #rustlang #ai

The second chapter of our "C to Rust Migration Book," written by @jonaskruckenberg.de, is on its way. The first chapter covered the basics. This one turns theory into practice, digging into the tools that make migrations work. Stay tuned! Read the first chapter here 👇 #rustlang

What does agentic engineering with Svelte look like in practice? Our Svelte lead @paolo.ricciuti.me built a real Svelte app with the agent writing every line of code, building up the engineering harness along the way so it produces good results instead of a pile of slop #Svelte #AgenticEngineering

Have you wondered what “context rot” really means? Agentic engineering is moving fast and so is the terminology around it. Our @paolo.ricciuti.me put together a glossary to keep it straight. Read the post 👉 mainmatter.com/blog/2026/08... #agenticengineering

Did you know C's int isn't actually guaranteed to be Rust's i32? They line up almost always, except on niche architectures. Rust decided that "almost" is close enough. Read about what this means in our free C-to-Rust migration course: mainmatter.com/c-to-rust-mi... #RustLang

rare PSA: we @mainmatter.com have our Rust engineers free right now! A client paused on budget timing, so they are coming straight off a highly complex c2rust project! some of theee best engineers I know, looking for the gnarliest problems you’ve got! 👀 DM me if your company has those!

Did you know struct layout in Rust is technically undefined? The compiler can silently reorder your fields to save space, you can watch it happen on Compiler Explorer. More in our free migration course: mainmatter.com/c-to-rust-mi... #RustLang

AI is changing how software gets built. In @paolo.ricciuti.me’s new blog post, he wrote up how the Svelte team built tools to guide agents towards writing good Svelte code, and why git, tests, and review matter more than ever. 👉 mainmatter.com/blog/2026/07... #sveltejs
