Seeing more modular gaming mice lately with swappable parts and weight tuning. Curious if this actually helps in competitive FPS or if consistency matters more. Anyone here used modular gear in serious play?


Curious what the HN crowd thinks matters most in camera comparisons — low-light, detail, or autofocus? Feedback will help shape the next update.

I created this guide because most “AI tool lists” online are either too technical. My aim was to make something simple enough for beginners who want to try AI without feeling overwhelmed. Happy to hear suggestions on what I should add or improve.


New analysis shows that a widely-publicized quantum computing “breakthrough” doesn’t replicate under closer scrutiny. Researchers attempted to reproduce the claimed quantum advantage and found conventional explanations for the results — suggesting the original announcement oversold what the device actually did.


One thing that surprised me in this piece is how quickly AI is becoming good at the parts of communication we assumed were uniquely human… It feels like AI is holding up a mirror not to what we say, but to how we listen


I like how they’re re-using old Samsung stock where possible and only switching people over as needed. It avoids unnecessary waste while still shifting to a more sustainable standard.


Microsoft is bringing Claude into healthcare workflows through Foundry — aiming at clinical and administrative tasks that require accuracy and compliance. Does AI in regulated medical settings actually improve reliability, or just shift risk?


Going through this page surprised me. A bunch of things I thought were “basic facts” like humans having only five senses, Einstein struggling with math, or seasons changing because we’re closer to the Sun turn out to be wrong. There are quite a few tech-related misconceptions in there too. Made me realize how many things we repeat without ever checking where they came from.


Why not to answer "I don't know" instead of hallucinating? I don't know Einstein's progress in math, I don't know how many senses are there.


Incredible story: In 1971, a tiny bug in AT&T’s switching software caused a cascading failure that took down nearly all long-distance calling in the US. The entire system collapsed because one switch sent a malformed signal and every other switch copied the same failure. Wild early example of distributed-system fragility.


I'll bet it is, but that link is a 404.


Yeh I can't find anything about this, only the outage in 1990:

This is a great example of how a small change in the right place can outweigh years of incremental tuning.


I don't think I've ever seen less than 10x speedup after putting some effort into improving performance of "organic"/legacy code. It's always shocking how slow code can be before anyone complains.
