🔥 Discover this insightful post from Hacker News 📖 📂 Category: ✅ Main takeaway: (Since a full rotation brings every point on the triangle back to where it started, mathematicians stop counting rotations past 360 degrees.) These symmetries are discrete: They form a set of distinct transformations that have to be applied in separate, unconnected steps. But you can also study continuous symmetries. It doesn’t matter, for instance, if you spin a Frisbee 1.5 degrees, or 15 degrees, or 150 degrees — you can rotate it by any real number, and it will appear the same. Unlike the triangle, it…

🚀 Discover this trending post from Hacker News 📖 📂 Category: 📌 Main takeaway: The years I’ve been working brought a lot of context, more scars, and more pattern recognition. You start seeing inefficiencies, problems. Like a lineman sees a frayed cable: obvious, dangerous, and actually … fixable. The reflex is to speak up, to suggest a better pipeline, a safer rollout, a saner incident process, whatever. But at some point you notice a hard truth: most of that unsolicited wisdom doesn’t land anywhere. Most of the time not because it’s wrong, but it’s inconvenient (for the moment), politically/socially awkward,…

Why are my headphones buzzing whenever I run my game?

0 CommentsEntertainment

💥 Read this insightful post from Hacker News 📖 📂 Category: 💡 Main takeaway: Background I use rust with my own engine working on an isometric-perspective game inspired from Gnomoria, RimWorld, Dwarf Fortress, etc. Whenever I started my game, my headphones were buzzing. I could play Fortnite, Overwatch or any other game and that doesn’t cause my headphones to buzz. It’s only my game. And it’s really annoying, as you might imagine. Why can I play Overwatch and Fortnite fine, while my isometric game makes my headset buzz? I had a fairly decent CPU, a 3090RTX card, 32GB RAM and…

You can’t fool the optimiser — Matt Godbolt’s blog

0 CommentsEntertainment

✨ Explore this trending post from Hacker News 📖 📂 Category: 💡 Main takeaway: You can't fool the optimiser Written by me, proof-read by an LLM. Details at end. Sometimes you’ll step through code in a debugger and find a complex-looking loop… that executes as a single instruction. The compiler saw through the obfuscation and generated the obvious code anyway. Consider this assortment of highly questionable unsigned addition routines - for variety, here compiled for ARM (unlike yesterday’s addition example). Despite these all being very different ways of returning x + y, the compiler sees through it all and recognises…
