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 ase + 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!

@ID_AA_Carmack 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

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 earn more: labs.iximiuz.com/challenges/lin…

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/goos…

@dadhi @mrangelo4199 @drk 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

quick demo of my current terminal multiplexer setup to end the week.
the thing to note: there is no client side terminal here. there's no xterm .js or ghostty-web. the terminals you see are plain, static html projections of the server side terminal state.

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.
I am giving a talk on AI and programming in a couple of weeks. I have an abstract but the talk is not ready yet.
What should I talk about?
The audience will be made of young people.

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 ↓
