This talk by @siosm.bsky.social covers the important work being done to enable verification for bootc images like ours. youtu.be/D7HqckeHlx8
"Using composefs and fs-verity, we can link a UKI to a complete read only filesystem tree, guaranteeing that every byte of every file is verified on load."

I’ve spent so much time chatting with AI and teaching them along the way that I’m starting to wonder if it’s time they start paying me back for all these free lessons!

Firefox changed their ToS recently, and it’s really bad. It’s disappointing to see Linux distros still setting Firefox as the default browser when security and privacy should be top priorities.

This might be my conspiracy theory, but doesn’t it seem like the food industry pumps out junk just so the medical industry can profit off our ailments? Are they colluding against us? We’re stuck in a vicious cycle—keep us sick, keep them rich.

🌍 Open source is a global effort.
It doesn’t matter where you’re from—what matters is that you’re building.
The best software isn’t built behind closed doors—it’s built in the open, by people like you.

Finally got to catch up with an old friend and we ended up having a super productive evening! We dived into open-source tools, demoed the Brave browser, explored the magic of Nix/NixOS, and talked about projects like secureblue and Trivalent. We also agreed Chromium’s security model is hard to beat.

Free speech is liberty's foundation. When America—historically its strongest defender—wavers, the world notices. Laws favoring 'safety' over speech open doors to censorship. Once government defines 'acceptable speech,' dissent becomes the target.

AI agents will be HUGE. With each new capability, attack surface grows. Attackers can poison training data, manipulate decision logic or use deceptive inputs to trigger unintended behaviors. One compromised agent can infiltrate entire networks. We need adversarial testing and monitoring.

Please make sure to use E2EE alternatives like Proton Drive. For those stuck in the Google ecosystem, tools like Cryptomator can encrypt your files before uploading to Drive. Not perfect (no metadata protection) but much better than storing plaintext.

Testing Ubuntu after many years (only for system hardening guidance). While I still recommend Pop!_OS over Ubuntu, I understand switching OS is tough. Let’s improve your current setup!
Reminder: we don’t recommend Ubuntu due to past privacy concerns, but it’s still far better than Windows.
