🇪🇺🤝🇨🇭 Switzerland is in the European research game.
The country is now part of Horizon Europe and the Euratom Research and Training Programme.
This means Swiss researchers can join forces with European peers to push the boundaries in health, energy, and digital innovation.
And the pace is up.
✅ Digital Europe and Euratom this year
✅ Fusion for Energy in 2026
✅ Erasmus+ in 2027
✅ EU4Health after
From CERN to space, it's time to aim even higher. For all to benefit.

Ended up giving away 80 of these "Open Book" SAOs at Supercon, and it was so much fun! Megathanks to @evan@krall.sh for helping with assembly. Fun facts:
First book requested: Catch-22
Last book: Moby Dick
The one I wore: The Little Prince
Most requested: The Hitchhiker's Guide to the Galaxy
Oldest: Robinson Crusoe
Newest: Fourth Wing
Oddest: a tie. the McMaster catalog, or the DSM-5
Number of people who brought my SAO on stage for their badge hacking demo: 4
New campaign subscribers since Saturday: 130

An eBPF Loophole: Using XDP for Egress Traffic
XDP is Linux's fastest packet processor but only handles incoming traffic. We found a loophole in how the kernel determines packet direction to make it work for outgoing traffic too!

Using XDP for Egress Traffic
XDP only works for ingress. We found a loophole that lets it work for egress. Here's how we did the impossible.

I'm getting the feeling that one of my 2026 resolutions should be to finally try and actually contribute to C-based projects aside from the kernel more. Maybe that will finally give me a similar level of confidence in that language to Go/Rust.

Flatpak now supports OCI registries! Hell yeah. Now the only thing missing is systemd-sysupdate support for fetching updates from there, and then every single piece of software I run is vendored through the same registry format.

New opinion that's growing on me: If software freedom on iOS and Android is essentially dead, then maybe it's ok if you make the iOS and Android apps proprietary as long as you vendor a proper, libre Linux app as the thing to push people towards
