New best story on Hacker News: Show HN: I built a hardware processor that runs Python

Show HN: I built a hardware processor that runs Python 914 by hwpythonner | 241 comments on Hacker News. Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions. I independently developed the full stack — toolchain (compiler, linker, codegen), and hardware — to validate the core idea. Full technical details will be presented at PyCon 2025. Demo and explanation here: https://ift.tt/NnE2xJ6 Happy to answer any questions

New best story on Hacker News: Cursor IDE support hallucinates lockout policy, causes user cancellations

Cursor IDE support hallucinates lockout policy, causes user cancellations 823 by scaredpelican | 289 comments on Hacker News. Earlier today Cursor, the magical AI-powered IDE started kicking users off when they logged in from multiple machines. Like,you’d be working on your desktop, switch to your laptop, and all of a sudden you're forcibly logged out. No warning, no notification, just gone. Naturally, people thought this was a new policy. So they asked support. And here’s where it gets batshit: Cursor has a support email, so users emailed them to find out. The support peson told everyone this was “expected behavior” under their new login policy. One problem. There was no support team, it was an AI designed to 'mimic human responses' That answer, totally made up by the bot, spread like wildfire. Users assumed it was real (because why wouldn’t they? It's their own support system lol), and within hours the community was in revolt. Dozens of users publicly canceled thei...

New best story on Hacker News: Tell HN: Announcing tomhow as a public moderator

Tell HN: Announcing tomhow as a public moderator 980 by dang | 306 comments on Hacker News. Hi all, Tom Howard is going public as HN moderator today. He has been doing HN moderation work for years already and knows the site and its practices inside-out, so the only new thing you'll see is mod comments from Tom showing up in the threads the way mine do. I'm not going anywhere, so you'll have two of us to put up with going forward :) I've known Tom since he was sctb's and my batchmate back in YC W09. Many of you know him as the kind and thoughtful community member tomhoward ( https://ift.tt/GP1uJIp ). He's still kind and thoughtful, but he's going to post as tomhow from now on ( https://ift.tt/hW1gKti ), the same way I switched to dang when I went through this rite of passage years ago. Below is a bit from Tom about himself. Please join me in welcoming him to this new status which he was crazy enough to say yes to! --- YC and HN have been a huge part of my ...
