The “opt-out" of your code from “The Stack” is a joke. No big surprise. But I first thought they have at least the decency to apply the opt-out before publishing - naive, I know.
They promise (pinky swear!) to remove your repositories before each patch release. Meaning existing datasets are not touched – your intellectual property is not removed. There simply is no removal at all! What a farce…

Maybe I'm misremembering it, but didn’t FreeBSD (like NetBSD) adopted a strict No "AI” policy?
The last mention of working on such policy I could find is in the status report for Q3 2025: https://www.freebsd.org/status/report-2025-07-202…
The awesome @nanoparsec reminded me about @PrototypeFund today 💕 And I can't stop thinking about it. Luckily there are a few months left before the next application phase starts.
Need. More. Ideas! 😅
I wished “interest in working with artificial intelligence” in a software engineering job description is meant as machine learning, computer vision, semantic modeling, expert systems, etc.

Haven't seen a big splash in the (IT) news yet, but apparently there is a 16 year old vulnerability in KVM which can be used to escape a guest and even take over the host (CVE-2026-53359): https://github.com/V4bel/Januscape. If /dev/kvm is…

Hot take (or maybe not): Not a single customer support contact got better by using "AI” (voice) chats.
What about you stop whining about supporters are too expensive and fix your products and services, make them easier to use and understan…
I also recently learned that the traditional coding case studies are more and more replaced with "vibe coding sessions”. Not a joke! Not only crazy, well funded US startups!
