I’ve heard of people doing ambient performance profiling by instrumenting their code to insert clicks into an audio buffer based on a high precision clock and piping it out a speaker. You get to learn the sound of your code at 44.1KHz

Back in the days of the PS2, you’d just take a couple of long triangle strips, give them a twist or two, then UV-animate a static texture up through them.

There are definitely athletes who spend their entire prime years working in the minor leagues trying to get their big shot in the majors and never quite getting there. It’s a life of constant travel, crazy hours and very little money.

Having grown up playing these games, I was a bit taken aback when folks online sometimes called me out for using ellipses "wrong". I had assumed it was common practice...

Having spent a couple decades making engines that did ship games, now I spend a fair bit of free time helping noobs make engines even though statistically nearly none of them end up shipping games. Making a game engine is a fun and highly-e

I knew a guy who would brag that he used Outlook as his build system 20 years ago. Builds would take 9 to 24 months depending on the complexity of the project. But, as the CTO of a mid-sized software company, it worked for him.

Note that the pre-sorting wasn't just for drawing. It was for loading as well. The PS1 only had 2MB of RAM and a 2X CD-ROM with a seek time of a 1/4 second or more depending on the distance traveled by the drive head. So, straight

Technically, the (pixel) fragment shader stage happens after the rasterization stage.

Back in the PS2 era of game development, we didn't have much of virtual machines to work with. And, making a shippable build involved wacky custom hardware that wouldn't work in a VM anyway. So, instead we had The Build Machine. T

For one, the project started in 2019 https://geminiprotocol.net/history/ So, I guess Google should rename their LLM? For another, to do that we'd have to follow something like the prescription drug naming process

I can imagine subpixel rendering being rather easy for SDF fonts. But, I can’t say I’ve seen it done.

Wuffs looks pretty awesome. Thanks for making it. Wuffs is intended for files. But, would it be a bad idea to use it to parse network data from untrusted endpoints?

“Shared mem” in CUDA and compute shaders works the same way. And, geometry shaders are very reminiscent of PS2 VU1 programming, during essentially computer shaders that can output directly to the rasterizer without going through DRAM.
