If anyone wants a nice side project... The fast number parsing fast_float (part of GCC, and other important systems like MySQL) is not always exact when dealing with 16-bit float parsing (specifically float16_t). That is, some number strings can lie in between two numbers and the rounding is wrong. In fact, nobody has done a proper analysis of the implementation to insure that it is correct. Yeah. I could ask my AI, but it is still work, especially because I do not trust anyone, not even an AI, to get it correct the first time around. Contributions invited. github.com

Co-founder of Modem and a founding engineer at Sentry, where he went on to be VP of Engineering. Co-author of Third-party JavaScript, and co-host of the State of Agentic Coding podcast with Armin Ronacher.
It's becoming normal practice to plug your coding agent into tools like Slack and helpdesk software to find customer insights. Turns out it's super inefficient, because you're just fetching and smashing raw strings into your context repeatedly. So we released a new MCP server that solves that. MCP Related

Here's my conversation with Anthony Kaldellis about the deep history of the Roman Empire in the west and the east (the Byzantine Empire). This was a truly fascinating conversation with a lot of wisdom for the modern world and for the future of human civilization. The Roman state lasted over 2,200 years. If we want to understand human nature, the modern world, and how humanity can flourish, it is valuable to study history, especially the history of why societies survive and why they collapse.

people say that uh you get into tech in order to change the world. If you want to change the world, then thinking about the impact that your technologies have on the world is part of your job.

Their words
if a revoked user still wants to, say, vandalize a document, they can just backdate their edits, give it an earlier timestamp. So, relying on clocks is absolutely useless here because people can forge the timestamps from those clocks and thereby then potentially undermine the access control mechanism.

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.
