I'm a pretty simple person, I see a treemap or hierarchical visualization and I am pleased.

A prop typed Item[] tells you what's inside the array, not whether you get a stable array next render. So I made referential stability a type. Inline array to a memoized child? Type error at the exact line. React + Preact, packaged as `stableref` 👇

I think it looks really clean, will definitely try it out.

What is this keming you are talking about? 🤔

Nah, I only use quintuple-equals, just to be safe.

Ah yes, that makes perfect sense. Thanks!

I mean, why it's not called field.value instead of field.input?

Jonas Røssum @nimrossum.com · 26/06/2026

I'm a bit curious as to why not all the props to the fields are spread to the elements. Is there a specific reason for this? 🤔

Jonas Røssum @nimrossum.com · 16/06/2026

I'm SO in! The other day I was completely unable to rename variables, because I was out of copilot credits 😑

@trueberryless.org one more new pfp member! I might join soon when defending my master's thesis 📸

Jonas Røssum @nimrossum.com · 04/06/2026

Oh, good point. I think I do it like that because I once read that there is a limit of the amount of args you can give to Math.max, but in this case it would make the code much simpler!

Jonas Røssum @nimrossum.com · 04/06/2026

This! I just migrated from an unmaintained args parser to parseArgs and it does everything I wanted! I even used the config that I pass to parseArgs for generating --help! github.com/git-truck/gi...

okay I swear, the publish workflow will work this time git add .github/workflows/release.yml git commit --amend --no-edit && git push --force-with-lease 🔁 repeat

This is a great bridge! I am excited about disposables being introduced in libraries API's, making cleanup cleaner and safer! Can't wait for it to come to the Atomics API's for mutex acquisitions. In the meantime, we implemented our own DisposableMutex here: github.com/git-truck/gi...

npmjs.com is critical JS infrastructure, not a side project. Wild that microslop shipped a half-assed, vibe-coded dark mode, with poor contrast, making README code blocks impossible to read. IMO this is a stewardship problem, not just a bad UI tweak. @npmx.dev could not have had better timing!

We're very proud of this release! We will soon publish a paper on it as well, stay tuned!

Jonas Røssum @nimrossum.com · 28/05/2026

Hmm... I will visualize one of your favorite repositories if you'd like?

Jonas Røssum @nimrossum.com · 28/05/2026

Sure, give it a go 😅 but I think there are some false positives for some reason!

Jonas Røssum @nimrossum.com · 28/05/2026

Yeah there is something funky going on with our tsconfig.json...

I'm looking for sponsors for Valibot and Formisch. If either library is part of your companies stack and you want to partner on what's next, my DMs are open.

It was a pleasure interviewing you, thanks for the insights and feedback, it's much appreciated!

💥 just released a github action: `uppt` it aims to be a very simple, secure release workflow for maintainers that adheres to best security practices ⚪ trusted, staged publishing on npmjs.com ⚪ github environment protection ⚪ generated release PR + changelog ⚪ automatic release + publish on merge ✨

I was amazed at how locked down it was, it's *very* secure!

Same story here! Discovered you could write macros in Microsoft Word using Visual Basic. I think I made a calculator or something. 16 years later and still coding in a Microsoft program (vscode) 😅

Big week: we officially moved into our new NY office 🗽 Now the fun part begins. I'm starting to build our engineering team from the ground up, and we're looking for talented software engineers who get excited about hard problems, tight loops, and shipping real things fast.

High five! I don't know what's happening on GitHub, business is booming!
