Performance Speed Limits (2019)

news.ycombinator.com Travis Downs 2025-10-18 11:06:10

How fast can it go? Sometimes you just want to know how fast your code can go, without benchmarking it. Sometimes you have benchmarked it and want to know how close you are to the maximum speed. Often you just need to know what the current limiting factor is, to guide your optimization decisions. Well this post is about that determining that speed limit. It’s not a comprehensive performance evaluation methodology, but for many small pieces of code it will work very well. Table of Contents Th

Video player looks like a 1-inch TV from the ’60s and is wondrous, pointless fun

arstechnica.com Unknown 2025-10-22 06:29:47

If a family of anthropomorphic mice were to meet around a TV, I imagine they'd gather around something like TinyCircuits’ TinyTV 2. The gadget sits on four slender, angled legs with its dials and classic, brown shell beckoning viewers toward its warm, bright stories. The TinyTV’s screen is only 1.14 inches diagonally, but the device exudes vintage energy. TinyTV 2 Specs Display Size: 1.14-inch Resolution: 216×135 Panel Type: IPS Dimensions: 1.9×1.4×1 inches (47.6×36.6×25.9mm) Ports: 1x USB

In Search of AI Psychosis

news.ycombinator.com Scott Alexander 2025-10-20 04:30:50

AI psychosis (NYT, PsychologyToday) is an apparent phenomenon where people go crazy after talking to chatbots too much. There are some high-profile anecdotes, but still many unanswered questions. For example, how common is it really? Are the chatbots really driving people crazy, or just catching the attention of people who were crazy already? Isn’t psychosis supposed to be a biological disease? Wouldn’t that make chatbot-induced psychosis the same kind of category error as chatbot-induced diabet

Researchers at King's College London have examined over a dozen cases of people spiraling into paranoid and delusional behavior after obsessively using a chatbot. Their findings, as detailed in a new study awaiting peer review, reveal striking patterns between these instances of so-called "AI psychosis" that parallel other forms of mental health crises — but also identified at least one key difference that sets them apart from the accepted understanding of psychosis.
