20 years ago I'd look for an InstallHook call in a Windows program. There are legitimate reasons to use hooks, but a game should have none.

Well, it's a good video but... Hacker News? On the related topic, you know how in Ford Mustang the engine noise is simulated so the engine would sound like a pre-emission-standards V8 even if it runs on just four? How about a similar t

I lead a small R&D team in Materialise's Kyiv office. Due to very demanding requirements (we need someone who can do math, write code, and communicate with other people reasonably well, often at the same time), I usually have to re

I think, type inference is a poor man's model checking. And it makes exactly as much sense as your model does. There is no such thing as a universal model. https://wordsandbuttons.online/static_typing_isnt_free.html Ad

I think this is brilliant! And, what's more important, practical. I did a similar thing a few years back for small linear systems: https://wordsandbuttons.online/outperforming_everything_with... The idea is essentially

No, it's all vanilla JS. Moreover, I don't even have internal dependencies, every page is written from scratch (with a pinch of copy-paste). This is a hobby project, and I like to program, so I'm just not interested in code r

This means that the more lexemes look alike, the more they need color difference the highlighting provides. Like 'coordinate_u' and 'coordiante_v' should be distinctively different, but 'coordinate_u' and &#x27

Wow! Didn't expect to see it on Hacker News again. Hello, hi! I'm Oleksandr Kaleniuk, and I wrote the thing back in 2020. Please don't take it all too seriously. There was COVID-19, I had nothing better to do. I did write a n

We used quaternions in our engine back in 2005-2008. Compared to matrix multiplications, multiplying quaternions was cheaper so we could save a few instructions here and there. But I never used them since. One reason being, I suppose, proce

What do you think about Geometry for Programmers? https://www.manning.com/books/geometry-for-programmers It has been recently published (April 2023) and not yet in any lists.

Have you tried reading code instead of smelling it?

This "level of abstraction" euphemism actually means "the level at which I'm not reading code anymore even and especially if I should". Of course, linear code is more readable! Linear everything is more readable. Ha

In a way, every static typed compiler has a bit of Prolog in it: https://wordsandbuttons.online/logic_programming_in_cpp.html

Cloning things makes maintenance harder linearly. Generalizing things makes maintenance harder exponentially. Counterintuitively, generalization only makes sense on small numbers or reiterations, not the vice-versa. I started https:/&

Ten years ago, Python used to be excellent as a second choice for everything. So if you dabbled in machine learning, web, statistical analysis, text processing, system scripting, computer algebra, etc, it made sense to learn some Python eve

You have to measure. It's a contextual optimization, no compiler in existence measures contextual optimization for you. Even the profile-based optimization is a spray and pray thing. CPUs are not getting better at division per se, but

Have you tried measuring the actual impact of this? This optimization is so old, I'm not even sure if it's still worth the effort. It definitely worked in the 90s. What you do here is you save on division, and lose on instruction

If you're inclined to write fast code in assembly, you will. If not - not. The thing is, optimizing compilers don't actually do any optimization in the classical sense. They don't do run-measure-modify loop as programmers do

You are right. The site is not fast because of Assembly, it is simply well designed. Assembly, however, pushes towards healthier design choices. You have to keep things simple since you are the one who pays for the complexity, not a third-p

There is a notion that programming is an extreme kind of poetry. Like with haiku, where there are rules, and the rules are formal, you can ratify an ISO standard on haiku rules; but they only support the structure and not the sense.

I've been wondering myself whether "software engineering" is a misnomer. We have so many of them in software engineering. What if creating software is closer to investigative journalism than to building bridges? Consider this

This just shows that we need a sustainable widely supported hardware platform for long-time operation. 30 years is not that long. I wonder if RISC-V could take this niche.

Back when I was active in academia, our publishers were reluctant to print source code or even repository links (that was largely before GitHub) but they could still share a paper source on demand. If you reference someone else's paper
