I'll be at @fosdem.org talking about how foundations can make ecosystem level investments to improve project sustainability. See you in Brussels?
FOSDEM 2026 - Ecosystems, Not Projects: Rethinking Open Source Foundation Funding
Open source foundations face growing demands, more projects, more users, more scrutiny, while still relying on fragile funding models built around grants, sponsorships, and donations. This talk…

Observability isn't a tool you buy anymore, rather it's a property of the platform you build.

If I had to summarize 2025 in a sentence, it would be that observability finally matured from a data business into a systems problem again.

Every server at Meta runs eBPF, 50% over 180 programs and they run on average across 20 different kernel versions

I think we will see more and more companies heading this way so check out this talk to see how they needed to re engineer their CI/CD pipeline

eBPF dev room schedule for FOSDEM 2026 is out 🐝

eBPF has become a normalized building block for infrastructure so if you want a single room that spans kernel internals, language tooling, observability, and networking, I'll see you in Brussels over a beer 🍻

Happy 10th Birthday, Cilium! πŸŽ‚

One decade ago, Thomas Graf pushed an initial commit with just a LICENSE, a .gitignore, and 226 lines of code. There was no Hubble, no Cluster Mesh, no network policy, no Tetragon, and eBPF still had a logo with a pea pod in it.
