Guess which one is Rust btw. 🤣 (The point is the language isn't a free lunch for performance. Rust could be just as small as any other here. It isn't a given. Fundamentals and system design trump everything else. Language wars are stupid as hell.) Quoting @mitchellh The Superlogical server is built to run anywhere and everywhere and serve a level of scale (terminals+clients) unmatched w/ prior solutions. So let's start talking about that, starting with memory usage and comparisons to other popular multiplexers. I want to start by talking high level: why does t… Related

Evan Prodromou has the unenviable task of making the whole ecosystem easy to understand. Thankfully he does that well. Things are logically laid out, there are comprehensive descriptions of even the most obscure parts of the spec, and it builds up nicely from the fundamentals.

During the weekend I built a contextual search tool for a photo library with 42k images across 2.8k galleries. The results are amazing! Turns out the AI models that generate embedding vectors from images directly are BAD at capturing the image contents, so I had to first generate captions and then generate the embeddings for the captions instead. Total cost: $30 for both captions (gpt-5-mini) and embeddings (text-embedding-3-large with 3072 dimensions). OpenAI Related

Their words
Playground by Richard Powers is a strange and wonderful novel set (mostly) on a remote atoll in French Polynesia that follows the tangled lives of an environmental advocate, a sculptor, a tech entrepreneur, and a brilliant bookworm trying to escape the grinding poverty of Chicago's South Side. The richly drawn characters drive the story, but what I love most about the book is that it's a love letter to the ocean with prose that comes closer than anything else I've read to capturing what it feels like to, for example, dive a thriving coral reef.

There is an algorithm called BM25 precisely for this, which is a more sophisticated version of TF-IDF. TF-IDF is term frequency times inverse document frequency, a very old-school information retrieval system that just works actually really well even today. And BM25 is a more sophisticated version of that, that is still beating most embeddings on ranking.

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.

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.
