alt Hacker NewsIt isn’t, but at the same time, smart hackers were working with highly constrained PC hardware in the 1980s and early 1990s and were cranking surprisingly good performance out of it. Folklore.org has plenty of stories about it, and John Carmack’s early career history is very impressive. We mustn’t forget the demo scene hackers either.
Recently I tried an approach of "just write the f*** code" instead of using infinite abstractions on a new UI side project. So for instance when you scroll, it shifts the pixels and just redraws the new exposed area. This is how stuff worked in the 90s. And it's blazing fast and uses very little memory. It's easy to mess up redraw code like that - in my case, when the window goes past the screen border and the pixels to copy aren't there. That's a bug we also had a lot of in the 90s.
