The 12” TV that I played SNES on had convenient brightness/tint/sharpness dials. Depending on my mood I’d turn sharpness all the way up for hard pixels or all the way down for a free Gaussian sampling filter ;)

When I started what you did was nothing but set up DMA streams to set registers. DMA sets registers, hardware reacts by rasterizing triangles. In the GeForce3 era, the registers got complicated enough they resembled tiny "pixel shaders

I've been programming GPUs since the PlayStation1. The way they work under the hood has changed fundamentally maybe 4 times in that span. I can't compare it to changes I've seen in CPU architecture since then. Maybe like: Com

That's not necessary. If a service has access to the raw audio of a show, it can fingerprint each second of that audio in a way that can be matched in a tiny amount of computation even for a recording in a noisy environment. That can&#

I know a guy who made a Shazam-like phone app that can listen to a few seconds of noisy audio and make a fingerprint that can be used to quickly ID those specific few seconds out of a pre-fingerprinted archive of an enormous amount of audio

Logo was my introduction to programming. Working on a 1 MHz Commodore64, my masterpiece was a fireworks show that was animated by the fact that the individual drawing commands were so slow you could watch them play out. So, draw a curve fro

On a CPU, hyperthreads are mostly replicated register banks. This allows the CPU to hold the context for 2 threads simultaneously. And, lets parts of a CPU make progress on one thread while the other thread is stalled. CPUs also has a kind

I can imagine abusing this to implement undo-redo for a game editor. Take snapshots. Record actions. Implement undo as: role back to a snapshot and re-run actions from the snapshot to the desired state.

Yep. It's my thesis that early GL APIs feel beginner-friendly because they are so hand-holdy, one-step-at-a-time. But, they end up more complicated when you get serious and they instill bad practices. Instead, the "modern" AP

I'm the opposite. Between work and family, I don't get a lot of time to hole up in a cave with an IDE for fun. Prior to LLMs, it was a struggle to get much of anything done. So, I rarely tried. But, now I can get ideas fleshed out
