Yes, instead of everybody contributing to one central codebase, we now have the same concept being rewritten a thousand times :-)

I did this more as an experiment but man it sucks, doesn't it?

We live in crazy times. I wanted to add a PID to the list for my personal use and since I use Rust way more than Go, I decided to one-shot one app, and Codex indeed one shotted it, wow.

This looks pretty cool, nice UI too. Gonna take it for a spin.

A while ago I worked on a similar idea, it was back when I was learning Rust so not super proud of the code, but I love the name of the tool: https://github.com/gistia/joindoe

Just ported it to rust and plan on maintaining it if you want to add it to your original comment.

I really liked the idea, so I am porting it to Rust https://github.com/fcoury/fracturedjson-rs

I have been slowly progressing on writing a Rust like language that compiles to JavaScript for a few years now. With the rise of AI and it becoming better recently with Opus 4.5, specially with Rust, I've been trying to have a speedrun version of it.

Think of it as TypeScript but with full algebraic types and other commodities from Rust:

Very interesting. Is it or will it be open source? Any links?

I thought Apple would get around and improve their memory prices with time, I guess it's the opposite: all manufacturers are now becoming Apple given these raises.

I wonder what Apple's next move will be :-)

Shameless plug: I did a series a couple years back, before AI was this huge, about writing a Vim-like editor in Rust, in case you want to play with it in the future:

It's interesting. I grew up in Brazil and if you don't know, we are very famous for having one of the most exorbitant importing tariffs in the world.

I thought that with time Brazil would modernize and get closer to the US in that regard. It's really sad to see the opposite happening.

It's sad to see that they have their focus on these while their flagship, once SOTA CLI solution, is rotting away by the day.

You can check the general feeling in X, but it's almost unanimous that the quality of both Sonnet 4 and Opus 4.1 is diminishing.

At first, I didn't notice this quality drop until this week. Now it's really, really terrible: it's not following instructions, pretending to work and Opus 4.1 is specially bad.

And that's coming from a anthropic fanboy, I used to really like CC.

I am now using Codex CLI and it's been a surprisingly good alternative.
