The issue with optionality only hit me after I had my first child. I realized that every year I spent single in my early 30s was a year I wouldn't get to spend with my future grandchildren. Optionality has hidden costs.

The social scene around AI and AI safety is more unpleasant than I realized. I'm sure there are other sides to it. But when you get a lot of men with too much money who think they're saving the world, surrounded by groupies, what do you expect? Read the long Bluesky thread about this, collected on one page: https://skywriter.blue/@segyges.bsky.social/3mvom4b4dn22q I can't confirm this stuff - I stay far away from this scene. And the sentence "AI Safety is Mostly a Sex Cult" is a massive exaggeration. But... (1/n) AI alignment Related

When there were just a few of us, we had meaningful relationships because we knew and liked each other. When we grew to between fifty and a hundred people, we had a community; when we grew beyond that, the sense of community began to slip because we didn't all know each other in the same way. That's when I realized that having groups (departments) of around a hundred (give or take about fifty) that are bound collectively by our common mission was the best way to scale the meaningful relationship. While bigger companies tend to be more impersonal, that is just another challenge that has to be… Related

Computer science professor who works on fast data processing; co-author of the simdjson parser and a weekly blogger about software performance since 2004.
One very visible effect of AI this summer has been a large influx of bug fixes. In some sense, it is the opposite of AI slop. I manage widely deployed libraries and, in some cases, the number of pull requests has been doubled. In the simdjson library, I merged 92 pull requests in 2024, I am at 134 thus far. In many instances, AI found long standing well hidden bugs. It makes me happy because I dislike bugs. But this puts stress on people packaging and distributing these libraries. Sadly, I have also never received so many pull requests that I have not merged. For simdjson, I received 219 pull… Related

Design engineer; formerly at Linear and Vercel; author of Sonner and Vaul; teaches animations.dev.
One of my favorite details of Sonner: By default the toast disappears after 4 seconds unless you hover over it. But what if a toast is triggered and the user switches to a different tab? 4 seconds would pass and the toast would never be seen. That’s why there’s a `useIsDocumentHidden` hook that checks if the document (tab) is hidden, and if so, it will pause the timer. This can be done with the "visibilitychange" event listener on the document. A small detail that improves the experience. Related

I think I’ve realized that GUIs, even though they have much better primitives for displaying all sorts of information and interacting with it, are also very restrictive. There’s usually only one way of doing things in a UI. You either love it or hate it. Which brings me to terminals and multiplexers. When you think about it, a terminal is basically a small GUI builder, letting you create your own environment from small, well-crafted tools that each do one thing well. So it’s no wonder people keep coming back to terminals. Quoting @mitchellh Quick Superlogical demo to end the week.

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.
