Hi @neuecc,
Do you know how to implement GetRef as instance method here:
public interface ITs<T> {
ref T GetRef(int index);
}
public struct Ts<T> : ITs<T> {
public T T0, T1;
public ref T GetRef(int i) {
switch (i) {
case 0: return ref T0; // ERROR CS8170
...
}

Code optimization is absolutely fascinating.
When you multiply something by a constant (let's say 24), LLVM replaces multiplication (imul) with a combination of left shift (shl) and load effective address (lea)
Left shift by 3 is the same as multiplying by 8, load effective address does math of [base + index] in the brackets, and then stores its result.
All of this literally to save 1 cycle. Because imul takes 3 cycles, and shl and lea take 1 each.
And you can find tables with similar heuristics for a lot of different constants. These people who write optimizing compiler backends spend so much effort to save just one instruction, so don't throw it all away!

I just made a programming language doing exactly this. As many address-space-reserved huge stacks as the program statically needs, with bump alloc, stable pointers, all compile time safe and yet way faster than what you can do in C++/Rust: github.com/aardappel/goose

Meet TinyFFR: a real-time cross-platform 3D rendering lib for modern .NET that doesn't mess around.
Native AoT, SIMD math, PBR, FSR, SDF text, skeletal anims, multi-format 3D models, and drop-in UI support (Avalonia/WPF/WinForms/ImGui).
Check it out: hubs.li/Q04BtBnJ0

How DNS resolution works 🔽
Ultimately, it all boils down to a simple network request to a DNS server. But which server to use, and whether to look up the name in /etc/hоsts or the local cache, depends on the resolver, whose behavior varies across Linux distros, language runtimes, and tools.

The "rewrite it in Goose" movement is already gaining steam, see here some early results of rewriting expertly written ninja/json/yaml/jq parsing in Goose and getting large speedups: github.com/calpeyser/goose-e…

yeah nats for sure. people use Kafka, but they shouldn't 😆
i wasn't happy with anything so made `xs`
as i'd experimented with composing actors, things would get rowdy quickly. that's why `xs` is able to run the actor for you.

A look into the current state of `xs`: a localfirst utility to work with event streams. As well as being great to orchestrate with @nu_shell, it now bundles an embedded Nushell interpreter, so you can register snippets of `nu` code for it to manage

this clip is just the projection visualization
the server emits HTML patches as a compressed brotli stream, which Datastar morphs into place
Just to not forget, I will try to attribute llm-generated in my projects with // todo @llm comments. So when coming back I can work them off and drop the comment when satisfied.

Testing database code can be such a miserable experience. Iit's flakey, it's slow, and often it's not really testing what you think it's testing. Someone should really create a database that makes unit testing as easy as testing regular functions. 😎

I remember being bothered a lot by AI being non-deterministic.
Not sure why it seemed like a big issue at the time.
Turned out to be not a problem at all.

Thanks to everyone who gave me ideas as what to talk about regarding AI and programming in my upcoming lecture. I will try to give credit.

TIL: "make -n some-target" prints the commands it would execute without running them.
It's a shame that it took me 15 years to discover this option, but now it'll definitely be one of my favorites 🔥

This is the closest to infinite context I've experienced.
I've been using it for a week to organize my life and build things (including itself!), and it just keeps going. I only use it now.
OSS next week, prompt to build your own below ↓
