IO bound compiler would be weird. Memory, perhaps, but newer CPUs also tend to be able to communicate with RAM faster, so...

I think just having LSP give you answers 2x faster would be great for staying in flow.

I've seen gcc+ld use a large amount of disk (dozens of GB) during LTO.

There have definitely been some applications of this sort of thing to speedrunning -- though far less sophisticated than the approach here, and usually only testing against a very small subset of the game. I've heard of some of this kind of work being done before on e.g. SM64.

I've also done something along these lines myself in Super Metroid. Mother Brain's neck moves in a conceptually simple but very chaotic pattern influenced by Samus's vertical movement, and there's a cutscene during the fight where the positioning of her neck can make a difference of about 7 seconds. The TAS fight used complicated movement to manipulate her neck position developed through much trial-and-error, while the best known human-viable manips were several seconds slower.

I wrote a program to search the state space for optimal movement patterns, and working with some speedrunners we were able to come up with a new human-viable manipulation that matched the previous TAS fight, as well as a new TAS manipulation that saved an additional 41 frames.

Very impressive! I had wondered where that MB manip came from. No surprise at all that it was you. :)

There's an appropriately minimal comparison with runit in her slides (PDF) from a talk she gave in 2024: https://leahneukirchen.org/talks/#nitroyetanotherinitsy

cout · 3 days ago

What I got from looking at that comparison is that runit starts a separate supervisor process for each process started. I like the cleaner process tree of nitro, but I wonder what the tradeoffs are for each.

In my experience, 80% of the links it provides are either 404, or go to a thread on a forum that is completely unrelated to the subject.

Im also someone who refuses to pay for it, so maybe the paid versions do better. who knows.

cout · 9 days ago

The 404 links are truly bizarre. Nearly every link to github.com seems to be 404. That seems like something that should be trivial for a tool to verify.

It's probably impossible to meet modern emissions, fuel economy, and safety standards without some computer control.

I haven't seen an analysis of whether regulations preclude those controls being open source and giving the car owner full access. Of course the owner could make the car noncompliant in that case, but the owner can do that on current and past cars using a wrench.

When we think of computers Er think of solid state digital computers. But the first fuel injected vehicles were mechanical computers. I suspect it's still very possible to do the same today, but not practical to design.

Also I'm trying to think of what role the computer plays in emissions other than ensuring stoichiometry.

Interesting. I tried to follow the discussion in the linked thread, and the only takeaway I got was "something to do with RCU". What id the simplified explanation?

Apple takes huge amounts of cash in exchange for making a search engine their default and they go out of their way to stop users from removing search engines or adding their own. Those apple sanctioned search engines are effectively paid ads, and apple users end up getting sold to those other ad companies with no option to use anyone else as their default.

The last good browser is Lynx

Why lynx and not w3m or links?

Actually Pydantic could be extremely useful if used in conjunction with SQLAlchemy, check out the SQLModel library, from the very same creators of Pydantic.

cout · a month ago

Having used sqlmodel recently for a project, I was underimpressed. Documentation was sparse, I found myself going to the source code to figure out how to solve problems I ran into, and I ended up dropping into sqlalchemy a lot more than I wanted. I think the idea is sound, but the code is hard to follow, and there are a lot of missing common cases.

This is the Javascript hipster effect. FastAPI and Pydantic are pushed heavily because of their fancy docs page and the evangelism which thrives on reinventing the wheel. So we are all now stuck with everything being Pydantic this Pydantic that, instead of existing frameworks which are frankly better.

Which existing framework is better?

Sort of a related tangent:

Some of the best gaming time in my life has been on handheld consoles, even when the games were available on PC or TV.

I wish there was a modern platform (not just a hobbyist Raspberry Pi kit or something) in the Switch or DS form factor, that boots straight into a coding environment like the legendary Commodore 64 and other "computer-consoles" of that era, with a central app store for indie devs to publish to for free. Add in dedicated support from a game engine like Godot, and I think something like that could spark a renaissance of solo devs/buddy teams experimenting with new game ideas and stuff.

cout · a month ago

Even if you had the machine, it is not enough.

What was magical about that coding environment is that you could go to the store and pick up a computing magazine and type in a game. Then you could play it and tweak it as you wanted. I have no idea what the equivalent would be today; the cost analogue I can think of is watching Mario maker or Minecraft videos and then implementing what you learn in your own world or level.
