HN is mostly dead to me. The site was billed as a place for curious minds, but there is little curiosity in letting a machine do your thinking.

I've had several instances of Kdenlive corrupting my save file, making them unable to be recovered. So no, that's not always a solution.

Lego's original moat was their patent. This expired in the 80s, and so their new moat became their manufacturing tolerances. None of their competitors could match the quality of their product. This lasted until about the 2010s when clo

Don't get hung up on the numbers or scale. The value of the doomsday clock is in the direction it's moving.

You're very correct but I suppose I was really answering why compilers centralize around SSA. It's a bold choice to choose one data structure for everything, and that requires more motivation than, "it makes certain optimizat

I like this article a lot but it doesn't answer the question of "Why SSA?". Sure, a graph representation is nice, but that isn't a unique property of SSA. You can have graph IRs that aren't SSA at all. And sure, SSA

Hey, this is my project. Cool to see it here again. You might like this article I wrote on the backend: https://pubby.games/codegen.html

Keep in mind that the ruling party has massively powerful surveillance systems at their fingertips. It's hard to say how things will unfold, but being a dissident may not be in one's best interest.

Well, they won two branches democratically. The supreme court is a different matter.

I remember playing that game once. The vast majority of the chat messages were some variant of, "I need a boy" or "I need a girl", meaning they were looking for dates. I guess boyfriend and girlfriend were banned, but bo

I didn't intend for my post to be about rural vs urban, or smart vs dumb. The point I was trying to make was that some people just aren't interested, no matter their background. You can find these people everywhere, which might ex

Something I've been wondering lately is how big of a blind spot I have from being habitually online. Like, I'll read the news, and I'll read political discussions on HN and r/politics and r/conservative and Twitter,

Take strings for example. In C you have to manually manage memory and there are a million pitfalls. Lots of programmers are lazy and use fixed-sized arrays and "unsafe" functions like strcpy which results in security vulnerabiliti

I mean it depends on the project and scope, but if you just write C-style code but use unique_ptr, vector, string, and <algorithm>, you're already at an advantage.

I've seen a few people/companies do this and it always baffles me. You don't have to use every C++ feature in existence, but a little bit here and there is far more productive and safe than writing C.

So here's the problem: you can buy an older cast-iron table saw with good precision and a large bed for $50-$150 on craigslist, or you can buy a cheap piece of made-in-china plastic at home depot for $500. The cheap piece of plastic ch

Trying to write a perfect optimizer is like trying to slay a hydra. Every time you address one weakness, two more are spotted. The overall approach has to run in polynomial time (or close to it), so there will always be missed optimization

I'd recommend just googling how a bike works instead of pursuing this argument. There's lots of good articles, like this one: http://www.cyclelicio.us/2011/bicycle-dynamics/ It looks like my theory on wh

Nah, that's not it. Try riding a bike in reverse (or pushing it). It's not at all stable, because the feedback is applied in the opposite direction. You'll fall right away, even though the gyroscopic effect is identical.

by pubby 2y ago
I've heard that the gyroscopic effect in bicycles is rather small. The balance instead comes from the positive angle of the front wheel, creating feedback. If the bike leans one direction, the wheel rotates to counteract it.

Thanks. I might sell some one day, maybe as a physical cartridge release as those have better margins. Mostly though I want people to enjoy my stuff, so a lot of what I release is free.

It's always a eucatastrophe[1] for me. Some random event occurs and it gives me something to focus on. Maybe a person shows up in my life, or an event, or an idea. Contrary to common belief, trying to pull myself out through sheer will

As a kid I did the math on all the lego sets, and came to the conclusion that the 500 piece bucket was the best bargain, beating out the 1000 piece bucket by a decent amount. Most other sets were an awful value in comparison. As an adult, I

OSB is much more nuanced than particle board, often in a bad way. Many manufactures orient the chips along a single axis, meaning it shares the anisotropic properties of solid wood where the X axis has a different strength and expansion rat

Something I realized recently was that you can just buy popcorn kernels in bulk and pop them in the microwave using a covered bowl. I don't think I'll ever buy instant popcorn baggies again.
