Btw, the bug itself was introduced in 30656c5e by Claude Code, and I guess.. improper human review and testing. https://github.com/RsyncProject/rsync/commit/30656c5e Someone using AI to bisect recent rsync.…
First question, bomb shelter?? Next what popped in my head, “Military grade means, made by the lowest bidder.”
Do not connect it to the internet. Problem solved. Basically anything in a social network needs to learn to defend itself against threats. Make computer a hermit, and it can go without updates for a long time. (Oh, but…
Maybe you'll like this, if you download this .html and view it, you'll see a random projection from a random spot on earth. https://gist.github.com/HenkPoley/8fa7a4a8e25f106585584463c1... Sadly mostly north oriented.…
Browser versions tend to burn more power.
LookingGlass' small portrait display is more like (2D) lenticular. Their larger displays use a micro lens system that directs pixels out in beams in different direction. So you also get parallax in the up & down…
I wonder what kind of rig is needed for recording that. It has to be at a least a few different viewpoints.

For the moment (well, february) the improvement with PHP 8.0 JIT is minimal: https://www.phoronix.com/scan.php?page=news_item&px=PHP-8.0-... But usually a JIT is made in a way that you can then move forward with your…
Slightly concerning that a few of their Netty benchmarks show high error counts. Usually meaning it could not handle the load, and behaved odd.
There a Turkish ham radio operators replying on the blog that they know of nothing of this kind. Maybe this "news" was made up?
Seemingly the only relevant reply in this comment section. That said, the article is kind of vague and has a few big misunderstandings unrelated to Tononi's Phi and Information Integration Theory. Phi is basically a…
What do you think of their recent Swift Playground programming education effort ?
Chris Granger (of Light Table fame) and his bunch at Eve are working on something like that. There are a bunch of presentations on YouTube. They are more looking at it abstractly as a possible programming / data model,…
Or donate some of the first blocks (s)he mined.
Just read the paper, it's explained. Or read the presentation, it uses pictures. Basically they run R, a single threaded statistics tool which is setup to hog a core, and in some other cgroup a wildly multithreaded…

Most recent Intel cores actually appear to be slightly slower at integer performance. http://imgur.com/a/2fiLF
A lot of their bugs are induced when you have a cgroup with multithreaded/-process tasks and a cgroup with just a few using processor time. Just testing one benchmark will not show it, unless you have something else…
It seems like everything with buffer/process queues needs a good polish to optimize for fairness. E.g. this is just being readied: http://blog.cerowrt.org/post/fq_codel_on_ath10k/ (also note higher throughput as result)
You check wether your system in NUMA with `lstopo`.
That might be what they call the 'overload on wakeup' bug. Maybe try the patch? I've read that the patch additionally needs a small fix, the goto label position went missing. Probably just before rcu_read_unlock() in…
This research applies to 'NUMA' systems. Commonly servers with multiple physical CPUs that each have a connection to their own memory banks. They can access memory of the other CPU by requesting it, but that take time.…
From what I understand from this presentation the 'scheduling domain' abstraction is reused through different layers of the hierarchy. So for example the two hyperthreads on one logical core are also modeled as…
The scheduler looking at an idle core decides wether to steal work from an overloaded neighbor. It will only compare over the interconnects in the figure (between domains). E.g. the the two cores in the dark grey box…
