@braelyn_ai just try difftastic. you would have incredibly less output.

Rust使いがunsafeを過剰なまでに嫌う理由は何なんだろう。少なくともメモリ安全の保証がないZigよりは十分安全だと思うんだけど
Theo - t3.gg@theo
uv has 350k lines of Rust, and 73 "unsafe" calls. The Bun Rust port is already 681k lines of Rust, and has over 13,000 "unsafe" calls.

@zack_overflow lol, how much do you earn? 10m$/year or what?? stop using phrase 100x recklessly.

Unfortunately, I don't use Zig now. Every 1.5-5x human DX productivity boost from Zig features is eclipsed by the 100x boost from coding agents writing Rust:
Allocator interface:
This is my favorite Zig feature, you feel so galaxy brain using a specialized allocator to optimize a code path (e.g. arena, stack fallback etc). The problem in Rust used to be that there was no Allocator interface equivalent and if you wanted a Vec that used a custom allocator you literally had to copy+paste the std version and modify it to use it (this is what Bumpalo did, look at the source). For a long while now there has been an Allocator trait in nightly, and it seems to be good now. Because it is a trait it is static dispatch, vs Zig's which is based on a vtable. Unlike Zig there isn't a community-wide convention of designing data structures to be parametric based on the allocator, but AI changes the game and makes it trivially to copy paste code and change that. I find it works well enough for my use-case.
Arbitrary bit width integers + packed structs:
Another beloved Zig feature of mine. It makes it so easy to do DOD-style CPU cache optimizations and stuff like tagged pointers, NaN boxing, etc. and even made bitflags really easy to make. You could always do this in Rust or any systems programming language but it was really ugly/unergonomic. The least worst option was using some crate like bitfield/bitflags which both rely on proc macro magic to work. Now, with coding agents I literally do not care how annoying it is to write the code by hand.
Comptime:
This is Zig's flashiest feature, no other programming language except maybe for obscure dependent-types langs have compile time evaluation as nice as Zig's. I thought I would miss it a lot, but I actually don't. For me, 95% of comptime usage is to create Zig's version of generic data structures with parametric types. Rust has a better designed type system IMO (see next section). In the remaining 5% of cases, not having comptime sucks. The only reliable way to reach an equivalent is through codegen. I'm making a game right now, and I have hardcoded hitbox geometry data generated from a tool that I want to bake into a data structure. Without comptime, I have to get Claude to write a script that generates the Rust file. However, I don't find myself needing compile time evaluation that much anyway.
Rust's type system:
I think I'd rather trade having comptime for Rust's better-designed type system, especially for bounded polymorphism (traits/typeclasses). Trying to do the equivalent in Zig is a nightmare. Also, I think that Rust's type system allows you to enforce more variants and prevent coding agents from making common mistakes. In my game I use the euclid crate which essentially allows you to not mix up coordinate spaces (very common problem in graphics programming) by creating specialized types for each coordinate space (e.g. Point or Point)
Not having to deal with memory issues:
With coding agents allowing 100x more code to be written, this also means you need to scrutinize 100x more Zig code for memory issues. Without formal verification, the surface area of the search space to enumerate to find bugs is just so much larger now. With the magnitude of code being generated now, Rust is even more attractive. Rust's tradeoff was always that it hinders developer productivity especially if you are unfamiliar with borrow checker, but this simply does not matter with coding agents anymore. And if you do use unsafe in Rust there's tools like miri which you can have the coding agent run the code against to make sure it doesn't cause UB or isn't violating Rust's aliasing rules when it comes to unsafe.
I still miss writing Zig and find it to be a great language but I like Rust more and coding agents work with better with it.

It's not a question anymore, most of Zig's best features were designed for human ergonomics, which matters less now All of Rust's best features came at the cost of added verbosity, which applies less to agents because they have superhuman working memory and never get tired

Okay but what about a 12 million line diff? That's the number of lines changed between linux 6.0 and 7.0.
This is instant in Diffy.

You know how you can render a 10,000-line diff without melting the browser? By focusing on simplicity. 🧵

@TechHighest are you happy? are you satisfied? how you feel about near future? etc.

@amariokoro @zeddotdev I think we too often turn to American models and very little to Chinese models... for me, the best closed-source models are American and the best open-weight models are Chinese.

@duanebester @saltyAom why it is not using builder pattern like in gpui? your chat app example source code look a bit weird for me because of that probably.

@syshukus People who run the hiring process should be the ones that an employee will be directly working with. And these people need to intimately know the job. This fixes most of the issues with hiring.

If you still don't hate recruiters enough, or if you are still not convinced that hr is the most incompetent, harmful, and entitled industry in tech, just watch this video.
But TLDR is "I have 20 seconds to find 5 keywords in your CV, but nobody taught me how to use Ctrl+F"

Tech is extremely starved for talent, but yet good programmers I know can't find a job. Hiring processes in tech is utterly broken, and essentially gatekept by reddit mods. Even though it's been solved a long time ago. Anyway, go watch the video: m.youtube.com/watch?v=nbxjb1…

@immatthamlin @zeddotdev maybe you tried to open zed wit sudo. i had his issue, because sqlite file was owned by root

a couple of minor annoyances with @zeddotdev recently:

@TechHighest @CringePoop isnt the problem that windows has so much surfaces for the same thing. probably created because different teams never communicared and than noone stepped to fix it.

@TechHighest Im thinking about getting my first mac. whats up with keyboard nd trackpad?
English
Software:
- I had less things break under Ubuntu than macos, and god knows how broken Ubuntu is.
- everything requires a third party app to fix. most of them are open source tho
Hardware:
- Keyboard & trackpad worse than I expected
- rubber feet are non existent
- Chrages fast

@Abhinavstwt in rust you can write `() = ();` because its both value, type and pattern to match(empty tuple)
