Steven and I put our tech vision for Clever Cloud on one page. I've said it before: cloud is software. Reliability starts there. So we combine our own tech with open source and build for versatility across infrastructures. Here's some of the work behind it: www.clever.cloud/technologies/

If you enjoy working with large-scale data processing systems and you want to stay relevant, you have to learn Apache DataFusion. Slowly but surely, it's replacing many other tools. The RAD stack (Rust, Arrow, DataFusion) is the future. One example: www.datadoghq.com/blog/enginee...

For a long time, I thought MySQL performance was far behind Postgres, at least for Kestra's database use case. But I was wrong; you can tune it to match Postgres performance; it's just a matter of the default configuration. www.loicmathieu.fr/wordpress/in...

New post on Foojay: Jenesis lets you turn your existing build scripts into actual build tools. No need to rewrite everything from scratch. By Rafael Winterhalter. Check it out: foojay.io/today/introd... #Java #BuildTools #DevTools

I've learned a *lot* about benchmarking in the past year, mostly by making a lot of mistakes. Here's what I learned (in talk-transcript form): hollycummins.com/benchmarks-g...

If you prefer a written version of how I think we should build Java programs, here's a blog posting on Jenesis: foojay.io/today/introd...

Narrator: It only got worse after we managed to automate the blind rewrites.

RIP Margaret Hamilton, the brilliant computer scientist whose contributions to software for the Apollo Guidance Computer were absolutely crucial to the Apollo Moon landings.

The stealth company I co-founded has a name: Hadronic. Java has a strong future, AI and agents are here to stay, and the best way to predict this future is to invent it. Why, and who we are hiring: emmanuelbernard.com/blog/2026/09...

I'm convinced Europe needs partnerships for digital autonomy. Because the point isn’t to own every component, but to keep technologies interoperable, expertise distributed and customers free to choose what comes next. @nivolle.com explains our approach here: www.clever.cloud/blog/company...
