Systems and developer-tools engineer at Cloudflare as of 2026, on durable infrastructure for AI agents; worked on React and PartyKit before that. Writes at sunilpai.dev.
overwhelmed by the response to this, I knew it was common but didn’t realise how badly people needed to see it acknowledged. fwiw, I learnt this most deeply on the react team; I joined what I thought was my dream job, and immediately failed in this fashion, leaving in a year. Quoting @threepointone new post: the senior engineer death spiral https://t.co/xzgU1jVBRh a friend just started a big job and asked for some advice. so I braindumped a monologue about a super common failure mode I see with engineers and posted it here, hope it helps whoever it can.

It's likely that more software will be produced next year than in all of the history of computing. It took Vercel 10 years to get to 1 billion deployments, but then we added another 1.4 billion in the last 10 months alone. Some of this will be tiny, personal and even disposable software. An HTML file with some javascript ("artifacts"), a report, a pricing calculator, a slide deck, all the way to sophisticated apps, agents and platforms. Deployment speed is one of our obsessions. We've brought down the time to deploy, upload, assign a domain and globally propagate an artifact to 1 second. This… Quoting @vercel_dev You and your coding agent can now use the CLI to deploy static artifacts in less than one second. ▲ ~/ vercel deploy ./my-static-site --prod JavaScript Related

Yep. Except: 1. This was about important internal tools.

I call this kind of thing 'cosplaying an enterprise production app'. All that complexity was in the way and using straight rails was perfect in that case. 2. I make calls like this all the time.

One thing that drives me crazy about the React ecosystem, and more specifically "tech influencers" and "thought leaders" in the space, is the infantilization of the developers using and working in it.

Or today’s discourse; Don’t use `useCallback’, ‘useMemo’, and React.memo. If you’re building anything beyond a simple CRUD app or a an incredibly focused app with few features, you _will_ need these features.

Their words
Did you know, the tests you write with react-testing-library look almost identical to the tests you write with vue-testing-library. Magic things happen when you don't test implementation details. :)

Wine writer and Master of Wine; Financial Times wine columnist, editor of The Oxford Companion to Wine and co-author of The World Atlas of Wine.
Their words
The World Atlas of Wine has unrivalled maps. Hugh did a fantastic job, the real spadework, of getting some top quality maps of the world's classic wine regions and many of the new ones. The original editions had Hugh's matchless prose, trying to encapsulate the spirit of each region in surrounding texts, but the maps are the thing, and some photographs.

What is a korrent?
A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
