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 ?

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".

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...

Really Cursed go.dev/issue/77930 TIL there exists such thing as syscall conflicts between Linux and vendor forks of Linux.

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 ?

In my threat model hackers have arms and USB cables. github.com/meshtastic/f...

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 !

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... 🚀

Working in hardware gives a whole new literal meaning to FIXME comments: > FIXME: this will blow up if 5V_EN and 50V_EN are concurrently HIGH, consider adding an interlock

When will a general purpose ISA add a programmable logic instruction ? One 4LUT per output bit, inputs indexed from 2×64bits source operand bits = 352 config bytes, with PTL 131456 transistors (11 transistors delay). Would replace many instructions in algorithms where each bit has different logic.

New debugging tech: have you tried turning on the AC ? I was debugging a random once a day crash in the go runtime, turns out my ram was at >100°C. Disabling XMP for now. Shame ECC isn't standard on consumer hardware.

It is 2025 and I had to send A LETTER. Disgusting.

After nine months of inactivity my 3D printer started failing all prints while I need to make parts for a manufacturing machine. I post a photo on a random discord and within minutes I get an expert telling me exactly what is wrong and how to fix it. Maker communities are truly a magic place.

Today the toolchain broke, so I've hexedit-ed the binary to fix a bug. « Everything is open source if you know assembly. » might not be as wrong as it looks.

What they don't tell you about software engineering is that on 11 April 2025 at 04H07 UTC+2 you will spend 40 minutes stare at the screen thinking, read thousands of words across multiple issues to catch back up, do a couple greps to check how things were done just to review a 1 LINE CODE CHANGE.

Google plans to move all Android development to its internal branch and then publish relevant updates to the Android Open Source Project when they're ready. AOSP isn't going anywhere, but updates will come less frequently.

My life: - Lurk in an open source project. - Spend a couple hours coding a feature wanted for months. - 😎 - Turn out you need to spend 10 more minutes fixing an edge case. - It now only works for you because you're the only Arch user and Debian ships a 20-month-old version of libuv.

@thepudds.bsky.social is my hero So far, up to 15x faster escape analysis for the Go compiler when compiling the TS checker package. End to end that's an 8x faster compiler of the checker package for us, bringing it down from 50 seconds to 6 seconds. github.com/golang/go/is...

TypeScript team: rewrites compiler in Go. Go community: what do you mean your new compiler takes more than a minute to compile? Unacceptable. Dishonorable even. We are so sorry for this sub par experience. Not how we do things around here. Two days later: WIP 5x speedup. HN: why pick Go anyway?

Awesome work by @thepudds.bsky.social github.com/golang/go/is... Compiling the typescript compiler went from 70s to 30s !

Today we're thrilled to announce our effort to port the TypeScript compiler and language service to native code, gaining a 10x speed boost in build times and editor responsiveness! devblogs.microsoft.com/typescript/t...

The most surprising thing in the typescript-go story is the number of C# devs feeling betrayed by Microsoft.

Useless go fact: Untyped expressions are not limited to the const realm. Using << and >> operators on an untyped LHS with a variable RHS produce an untyped variable expression.

The ESP32 backdoor conclusion from an offensive PoV: If you are running code in ring0* you can read, write and execute arbitrary code. *note that the Core used in the first ESP32 lacks an MMU like the vast majority of MCUs.

Tomorrow's side quest, figure out why the first function compiles better than the second one: func good(x, y uint) uint { return min(x, y) } func good(x, y uint) uint { return min(y, x) }

Today's mood: - 12h00 I guess I am writing Java - 15h00 Fuck Java why am I doing this ?

So much fun waiting to be had, I just noticed the go compiler lacks RISCV64 C & B support even tho GORISCV64=rva2020u64 & rva2020u64 respectively allows us to use them.

Wake up babe new Agile manifesto just dropped ! agvxov.github.io/fdd/fdd_mani...

Ok hear me out, Factorio asynchronously autosave while playing by forking to create a COW of the memory space. What if we did the same thing for Go tests ? The scheduler would fork on each scheduling decision and run all paths, this allows to prove some concurrent is always correct via bruteforce.

Hype new interprocedural analyzer for go1.25's optimizer: - Interprocedural backward register allocation go-review.googlesource.com/c/go/+/636839 - Side effects marking for functions go-review.googlesource.com/c/go/+/637936 - backward propagation of proofs (I'll code that later) - ...

Tips: - Types, use them !
