I've just finished a deep-dive on Intel APX github.com/golang/go/is... and the new CFCMOVcc and CCMPcc (as well as CTESTcc) instructions look very cool. You can remove branches from && and || even if they have (basic) memory side effects.

New surprisingly good go optimization, I've reduced the codesize by 2% with a simple change ! This changes the end of most functions from 2 instructions: add %rsp, $offset pop rbp To a single: leave Once encoded we go from 5 bytes to 1 byte. go-review.googlesource.com/c/go/+/548317

I am trying to move my browser to TLS1.3 exclusively and the only thing that broke today is bsky.app, please fix.

I hate computers, something I've done close to 20 times stopped working because my computer became TOO FAST. TIL the rpiboot usb gadget doesn't handle throttling properly.

Just installed Sunshine and Moonlight, crazy good. The GPU encoding performance is awesome. Sadly using HEVC not AV1 as only one of my computer has an hardware AV1 implementation. (the one using intel arc)

Working on the go compiler, is my commit too big ?

Countdown Standard xkcd.com/3232/

Highest level cryptographic rage baiting. www.youtube.com/watch?v=M1si... There are not enough words in all the world's languages to describe how mad I am; well done. Tom went out of his way to make the worst possible TLS implementation. Meanwhile calling my positions "toxic max security".

No one can force me to have a secure website!!!

Everyone pays for search. The only difference is what you pay with.

I just published kotama, an experimental GOOS=tamago compiler branch that allows execution of a rich example in barely 6MB of RAM, running on an rv64imfc CPU (yes, no d or a extension). This paves the way for supporting aifoundry.org Minion cores! github.com/usbarmory/ko...

This one is pretty funny go.dev/issue/77934. Turns out a struct used for Go ←→ Linux syscalls use int64 when Linux expects int32. But by chance this can't cause a bug because: 1. it is the last field of the struct 2. the size of the struct doesn't change since C aligns int64 to 8 bytes on 32 bits

I cold compiled Firefox today. Not in artifact mode, a complete compile. And it finished in 35 minutes ! 35 !!! Linux takes a bit more than an hour. I was ready to come back tomorrow. How is it so fast ?

Hum that compile time versus number of lines of code in the function looks O(n*n) suspicious.

Playing factorio in real life: The factory is growing ! 2nd Pick-and-Place and 4 3D printers print-farm (4th one is bigger and doesn't fit).

Feeling like that time someone merged a completely empty commit description and title to the Linux kernel.

Ok so I did the math, results are crazy. My household is currently paying 0.19€/kWh this is 3312€ a year, yes it's a lot, reasons include a broken heatpump and 2EVs. For 1k€ I can buy 5kw of solar panels, a 6kw for 1.1k€ more. As you might have noticed, if I install them myself, 2100€ < 3312€.

Never before I thought the performance of rm needed to be improved. I need to remove a single directory with a few hundred millions of files. I know it looks insane but it's on a modern file system (btrfs) so it works fine. Anyone got multithreaded faster alternatives to suggest ?

TIL openssh-client now warns you with a very helpful error message if the server does not support post-quantum cryptography. Gotta update my robot vacuum I guess.

Enjoying the end of the winter freeze and you ?

I need to make a story inspired on Roko's Basilisk but using instrumental convergence as a premise.

Feels like writing assembly minus the part where you typo on letter and create an Remote-Code-Execution vulnerability. Really exciting stuff to play with !

Go 1.26 brings the long-awaited vectorized operations (SIMD) in the simd/archsimd package. Since it's hard to create a portable high-level API, the Go team decided to start with a low-level, architecture-specific one and support only amd64 for now.

Straight from an episode of MacGyver Russia's new Anti-Air drone consist of a manpad (shoulder mounted anti-air launcher) attached on top of a shahed (originally Iranian kamikaze fixed wing UAV).

If whole engineering fields had to designate a single thing as their friend. - Software would be computers. - Civil would be concrete. - Electronic would be Kapton tape.

It's 2026 and I don't believe I am saying this. But I am paying for a search engine because the experience is superior to google (Kagi). Much faster that google with it's bloated tracking. Results are more relevant to what I care about.

Ooh, the SIMD WIP stdlib API for #golang is ready for people to poke! From Cherry from a few minutes ago: > As of today, we've landed a preliminary version with a reasonable API coverage. You're welcome to check out the dev.simd branch and try it with your use cases. github.com/golang/go/is... 🚀
