GPU people are so pretentious.

This is maybe a hot take, but I think game devs hurt themselves a lot by defaulting to either Unity or Unreal.

Human nature is to oversell things:

People who say "C is modern-day assembly" usually way undershoot it.

When it comes to pointers, "just use 64 bit integer" is way more intuitive to me.

@valigo If there's a benefit to doing something, it seems to get pushed to the extreme.

@valigo We did it since the beginning of times:

@valigo Bro everything is just in the cloud (other peoples' computers).

@valigo if by "hardware locks" you mean things like x86's `lock` prefix then there's a difference - that guarantees atomicity but unlike SW locks it can't deadlock etc so forward progress and correctness are both guaranteed.

@valigo This very post is an example of this.

@valigo it's not us, it's the marketing people.

@valigo "we"? Speak for yourselves

Mar 13, 2026

@valigo Why are you lumping everyone together? I understand that you are exaggerating for effect, but such provocations are, at best, pointless.

Mar 13, 2026

@valigo "serverless" doesn't mean better, it means you target a particular runtime and set of constraints and you get desirable scaling properties.

Mar 13, 2026

@valigo as engineers we need to be especially careful because it’s really all about trade-offs.

@valigo I would say we have shallow understanding where we gonna end as designers / researchers / engineers

@valigo Mike Acton is e-celeb tier

@valigo Wow python is fucking slow as its not efficient as something like C++

@valigo "Imagine working your ass off, praying to a statue of Mike Acton in your bedroom, and then some twitchy manager on cocaine demands that you transpile 6 years of hard work through a [spiritually] Python interpreter".

@valigo Interestingly, if you try to write Rust in this way, pointer provenance will cause misoptimizations that break everything.

Nov 18, 2025

@valigo Wouldn't this make working with arrays more difficult? Array[1] would have to be Array[sizeof(data)] etc

Nov 18, 2025

It is confusing if you aren't used to it, that is true.

Nov 18, 2025

@valigo Pointer arithmetic based on type sizes makes sense when considering aligned load/store memory operations.

Nov 18, 2025

@valigo For real I'm parsing through a binary array and trying to say "the next byte is a uint8_t, the next two bytes are a uint16_t" and the most elegant way to do it is mind-numbingly ugly pointer bullshit.

@valigo I had the displeasure of being exposed to Hex-Ray’s decompiler for years so I have gotten used to it, but it is annoying ye…

@valigo His style goes a bit beyond that, judging by the defines used it’s similar to some form of literate programming but with C preprocessor.
