ooh my talk on cancelling async #rustlang got featured on LWN! Thanks @pietroalbini.org for linking me to it

What if typescript was right about union types...? cirw.in/blog/typescr...

A better for loop? cirw.in/blog/for-yield

🦀 Talk by @conradirwin.bsky.social, Software Engineer at @zed.dev Modern computers are fast, but modern software rarely pushes them to their limit. Conrad will share how Zed’s GPUI can render a new frame to the entire screen every 8ms. Book your ticket ➡️ eurorust.eu/talks/render...

Makes sense! Also reminds me of this classic: pages.cs.wisc.edu/~remzi/Naur....

Finally figured it out well enough to write it down. zed.dev/blog/why-llm...

Who says AI can't build amazing things... www.windowswen.com

I first wrote up the idea for this 6 years ago, but it took a huge amount of work to actually turn it into reality. Thank you to Orion for the heavy lifting, and all the other Automerge contributors for making it happen!

Are there any statically compiled languages with a typescript-like type system (that can use values in types)? I love rust's exhaustive enum's, but I don't love that they're not just structs, and so you *have* to use a match statement to extract values instead of if…

In the modern world, we should refer to it as "unplugging a flower", not "picking" one.

Finally added `U` to Zed's vim mode; Closing in on being able to complete vimtutor. Only a few things left: * `%` matching in plain-text files * :set ic * :<range>w * :r <filename> !!!

I've (finally) written up the spec for CONL Schema conl.dev/schema.html (next steps publish the language server so it's useful; but feels nice to have found a *significantly* simpler model than JSON schema)

Exciting times! blog.superhuman.com/superhuman-i...

Really love building little details like this. Notice how in the search bar the newlines show up (instead of hiding your multiline content off-screen...)

If `git config --global user.email` reads my email from ~/.gitconfig; what does `git config user.email --global` do?

If you missed my talk at Rust week, or just need to hear the jokes for a second time, it's now online! www.youtube.com/watch?v=5z9D...

To garbage collect or not? cirw.in/blog/garbage...

Trying to reimplement a fun vim easter egg with an LLM...

Petition for all rust crates to copy `schemars` naming convention so we can sound like pirates when reading Carrrrgo.toml

cirw.in/blog/conl hot off the press, my new config file format

"commits messages should be meaningful" me, a professional:

Naïvely pasting “curl | bash” is insecure. I am not naïve. Therefore, I shrewdly type “git clone && make” instead to get the artisanal security nightmares.

I'm giving a talk on Vim at Rustweek. I want to share some "omg" vim tips – anyone have favorite "aha" moments, or obscure-but-useful key mappings?

Come to the Netherlands! Learn some weird vim stuff from yours truly! It'll be fun! rustweek.org/talks/conrad/

Working on improving our diagnostics rendering in Zed. Let me know if you have good examples (or particular pain points) to consider

So excited for this! (but in full transparency, I'm not a co-founder at Zed :D)

We are welcoming @conradirwin.bsky.social to #eurorust25! 🦀

Sometimes I wonder if the vim contributors were just trying to make it hard to copy

Been working on this for the past few months: feels great to finally ship it! zed.dev/blog/git

Dear Github, could you pretty please show the PR number in the actions title, not the run number. I want to click on the PR all the time, and I've never needed the job number (I just copy paste the URL around to communicate about action runs).

Rust proposal, the pub modifier should get longer the more public things get, right now it's backwards. fn a // private p fn a // pub(super) pu fn a // pub(crate) pub fn a // pub

We engineered Zed to be instantly responsive, but what's faster than instant? Anticipating your next move. Introducing edit prediction, powered by Zeta, our new open-source language model. 🚀

Is AI the end of satire?

Ahhhh zed.dev now lets you search ("/" in vim mode, cmd+f otherwise) within search results, a HUGE quality-of-life upgrade for me!!! I've been wanting this from the beginning ✨

As a follow-up to this post, I wrote down my extended thoughts on switching from Neovim to @zed.dev. sgoel.dev/posts/trying...
