☢️ Systemd 256.1 Fixes "systemd-tmpfiles" Unexpectedly Deleting Your /home Directory - Phoronix

Anyone know if RIFF chunks with id "\0\0\0\0" (4 zero bytes) with zero size is valid and a thing? I've seen WAV files multiples times with these in between other chunks or last in a file. Can't find anything in specs about it, most players and decoders seem to ignore them.

I heard someone complaining "Why did they have to put pixel art on the Museum of Ethnography?!"

Reader, they are traditional cross stitch patterns.

Man, I just spent two hours ricing tmux instead of writing my article that's due next week. #Linux really is the ultimate procrastination tool.

Title: CVEMITRECVSSNVDCNAOSS WTF

Abstract:

Bogus CVEs, know-better organizations, conflicting databases, AI hallucinations, inflated severity scoring, security scanners, Jia Tan. As the lead developer in the curl project, Daniel describes some of the challenges involved and what you need to do to stay on top of security when working in a high profile Open Source project running in some twenty billion instances. Involving many examples from real life.

Last year European Parliament and national parliaments rejected the “EU child porn scanner” that was set to be installed on every phone. Apparently this week we’re going to ignore all that parliamentary action and mandate such a scanner once more. Here’s what I wrote earlier on how this super scary thing would work in practice: https://berthub.eu/articles/posts/client-side-scanning-dutch-parliament/

I watched the new Practical Engineering video on the bridge collapse, and Grady said words to the effect of "all the work was partitioned out. nobody had a complete view of the situation. the people who really saw the problems had no autonomy to do anything about them, and the people with the authority to do something never saw the full picture - all they got was a piece of paper with action items", and I've never nodded along to something so hard. This happens aaaaalllllll the time in security.

Hey you fine people: Our agenda for the birthday party is public now: https://troopers.de/troopers24/agenda/ #TROOPERS24 See you next week! 🥳

Last year in "How I choose a security research topic", I used two unnamed attack concepts as case-studies for fast failure. I can now reveal both unnamed techniques were timing attacks. I'm happy to say my third attempt went better!

somebody asked how people who have historically been anti-copyright could be against AI content theft, so let me give this a shot:

Information wants to be free to enrich human knowledge. It does not want to be free to make human knowledge worse to enrich the pockets of assholes

Our tl;dr from @RealWorldCrypto

FYI, there is a bug in systemd. So, running: "systemd-tmpfiles --purge" will delete your /home/ in systemd version 256. #linux

Transparency baby.

The new Intel Skymont architecture details, as presented brilliantly by Chips & Cheese¹ (strongly recommended) have a very "inspiring" paragraph:

"Skymont duplicates microcode for the most common complex instructions across all three clusters, letting them handle those instructions without blocking each other. Intel gave gather instructions as an example, which can load from multiple non-contiguous memory locations."

Intel is calling this nanocode, I am calling this a new playground...
