Autocompleting text with known values seems like an easy problem to solve, but so so so many UIs get it wrong. I see this frequently enough that, rather than complain about them individually, I though I’d just write down the set of rules they often break.
Today we're announcing the most-significant evolution of our platform — something we've been building towards for a long time that we're thrilled to share with you. Introducing Multiplayer: code with friends in the same editor, execute programs in the same interpreter, interact with the same terminal, chat in the IDE…
The demoscene is about producing cool real time works (as in “runs on your computer”) called demos . Some demos are really small, say 64 kilobytes or less, and these are called intros . The name comes from “crack intros”. So an intro is just a demo that’s small.
Async Python is slower than "sync" Python under a realistic benchmark. A bigger worry is that async frameworks go a bit wobbly under load.

It's not that hard to build a coding agent. 300 lines of code running in a loop with LLM tokens. You just keep throwing tokens at the loop, and then you've got yourself an agent.
C-Reduce is a tool by Regehr and friends for minimizing C compiler bug reproducers. Imagine if you had a 10,000 line long C file that triggered a Clang bug. You don’t want to send a massive blob to the compiler developers because that’s unhelpful, but you also don’t want to cut it down to size by hand. The good news…

You are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites . This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.
Over the last few years, static type checkers have become available for popular dynamic languages like PHP (Hack) and JavaScript (Flow and TypeScript), and have seen wide adoption. Two years ago, a provisional syntax for static type annotations was added to Python 3. However, static types in Python …
