Wait. When submitting a stack though github cli, it doesn't set the remote tracking branch? I'm sure the cli submits the code via git, since I had to unlock my SSH key.
If I had push.autoSetupRemote enabled and gh cli would have chosen a different branch name, I'd have two remote branches?

Now that everyone is moving to stylex I feel like surimi.dev was a good idea after all.

Coding used to be my hobby. For a long time now, it's been my job and it's really hard to treat it as a hobby (even with fun side projects). BUT:
I feel like "coding without AI" could become my hobby again. I really crave hand-crafting code without AI but that's hard to justify in my day job.

Just remembered I have the vite-plugin-slidev npm package. Started to work on a nice integration but let it slide (Pun intended). Does anyone want the package name to do good?

Tangled will take over the world (GitHub). It'll take years but I'm willing to bet on it.
I never made that bet on bitbucket, gitlab etc. But I have a feeling.
Today vitest overtook jest in weekly downloads. Something I wouldn't have bet on a few years ago xD

Emptied a variety of antiquities and rarities from one shipping container into two, much smaller, shipping containers.

A couple of years ago that unicorn was considered an Easter egg. Only a handful of people in the company even knew about it.
Now it's a meme. And a bad one.

I love that Github is finally building UI features again, but did they have to hire the team that built the AWS web console UI to do it?

I had so much FOMO about Atmosphere conf. But now that everyone talks about how great it was... yeah no. I missed out.

p75 and p90 JavaScript bytes on the web have exploded since May, 2025—easily the largest 10 month period based on HTTP Archive data since 2023.

The Cursor editor is getting worse and worse for me over time. I'm discovering more and more bugs every day. And they're all stuff unrelated to Vscode but rather things that seem to be the cursor extensions like agents.

So what do we think about edge.js by wasmer?
github.com/wasmerio/edg...
Being known as the WASM guy amongst my friends, I'm still a bit skeptical. But if this can evolve into an open source alternative to WebContainers/Nodebox, I'm sold.

Hey @npmx.dev folks! Wondering if the package size badge on npmx considers the size of dependencies that must be installed? E.g does it check the actual install size via bundlejs or similar? (I doubt that but you never know with npmx xD)

The Error code property proposal looks super promising. I wasn't aware just how well aligned the ecosystem is when it comes to error codes.
Using instance-type based error classification is more elegant, but not really applicable for Javascript.

Anyone here knowledge in how vite and Vue/nuxt work together that can review a PR? I can donate some money for the effort, but I can't go down a rabbit hole to understand the entire environment API thing with the vue vite plugin.

Two things about knip.dev I don't get:
- how did we live without it for so long
- how did @webpro.nl NAIL the timing? Gave it to us right when AI started to produce left-overs in our codes faster than we ever could.
