It's best to avoid the feature for now 😔

Rails Needs New Governance Ages ago, when I was still a student, I taught myself Ruby on Rails for my senior thesis and fell in love. Fifteen years later, and I’ve used Rails at every job I’ve ever held in the tech industry. Fifteen years, and I still love Rails! But there’s something rotten at its core, and we share a name.

Is there a tool that, given a set of .d.ts files, gives you the minimum version of TypeScript supported?

TIL @nuqs.47ng.com requires TS ^5, and that requirement came in silently as a feature was merged (const modifiers on generics).

I need to automate this to prevent further type breaking changes.

MIT report: 95% of generative AI pilots at companies are failing There’s a stark difference in success rates between companies that purchase AI tools from vendors and those that build them internally.

MIT’s NANDA initiative found that 95% of generative AI deployments fail after interviewing 150 execs, surveying 350 workers, and analyzing 300 projects. The real “productivity gains” seem to come from layoffs and squeezing more work from fewer people not AI.

A screenshot from the tsup repository showing a text above the heading: "Warning: This project is not actively maintained anymore. Please consider using tsdown instead. Read more in the migration guide".

tsup is not actively maintained anymore 👀

With >9M NPM monthly downloads and >10k GitHub stars, tsup is undeniably a popular choice for bundling. Unfortunately, it is not under active maintenance anymore.

Thanks to @egoist.dev & contributors for all the work on tsup 🙏🏻

Rolldown Integration Next Generation Frontend Tooling

In the latest @rolldown.rs powered @vite.dev version, we've enabled the rust-based resolver plugin by default!
This will lead to even faster builds in case you don't use the experimental native plugins yet.

Wanna try out more native core plugins? Then enable them and make sure to use rolldown-vite

the main thing that makes me uneasy about llms is the cultural backdrop of global war on knowledge. the war on knowledge isn’t new but now it’s cheered on from tech too. tools for thought pivoted to slot machines because that’s what people want. “how things work” is buried under opaque indirections

obviously actual domain knowledge isn't going anywhere so it seems like the gap between more experienced and less experienced developers will widen? with less knowledge transfer and incentives to learn. i've learned a lot from conversations i'm no longer observing

👀 React + throw a promise technique, soon deprecated?

If you throw promises to trigger Suspense boundaries, it looks like a good idea to migrate to React.use()

PR not merged yet, but it's likely React will print a warning

Added a new feature to help users resolve version mismatches between the CLI and the plugins (breaking changes in the WIT files).

#WebAssembly Component Model is promising, but examples are either too simple or too complex.
