Did you know #FoundationDB's simulator randomly swaps disks between machines on reboot? 75% of the time. On purpose. I wrote how this works: interface swapping, BUGGIFY chaos injection, and how we use it at @clever-cloud.com to build Materia. pierrezemb.fr/posts/diving...

Digital edition of my fourth book, Crafting Engineering Strategy, is up for purchase! (Print copy should start shipping in next 2-3 weeks.) Tried to apply "Staff Engineer" formula to eng strategy topic, with a lot more editing 😂 www.amazon.com/Crafting-Eng...

At long last, @chris.blue and I have submitted the final manuscript of Designing Data-Intensive Applications, second edition, to the publisher. There is always more that could be improved but at some point we just have to call it done. Now it goes into production; probably shipping in ~4 months.

Want to get paid to work on open-source Rust? We asked David Wood, who leads the Rust team at Arm, how to land a "dream job" at the intersection of systems programming and core open-source contribution. His advice for up-and-comers:

The #foundationdb crate is approaching 10 million downloads (currently at 9,998,027) 📊 Thanks to all users and contributors 🦀 crates.io/crates/found... #rustlang

I just published: "Testing: prevention vs discovery" 🧪 Claude Code autonomously found and fixed bugs in my #deterministic #rustlang #simulation 🤯. The FoundationDB/TigerBeetle/Antithesis approach to #testing works, and now #LLMs can participate. pierrezemb.fr/posts/testin...

What happens when the Oxide API is slow? A podcast episode! More specifically, one about how the team employed all manner of debugging techniques to track it down to one obscure async runtime feature! Our colleagues joined me and @bcantrill.bsky.social to discuss youtu.be/4nU4JDG_zPs

As a person who's building a plugin system based on dynamic loading, Rust and FFI, this feels very refreshing www.redpanda.com/blog/multi-l.... Just use gRPC over a Unix socket! I'd love to see a performance comparison though, going over gRPC must slower, even with batching.
