I wrote one of those once! It was a nightmare morass of one-pixel errors. Maybe there was some clever simplification I missed that would have made it all easy, but these days I use the libraries. :P

I know that's how stb_truetype's renderer works, incidentally. Don't know if Freetype is the same, but I'd be mildly surprised to find it wasn't.

The geometry may be flat, but relationships between objects are still arbitrary, so light can still hit things from any angle. Try as you might, you can't escape curves. ;)

That article's a classic; definitely worth a read for anyone interested in graphics.

Whoops, yeah, you caught me. As I handwaved in the post, there's a little bit of implementation detail in the real code that I removed to clarify the algorithm. Fixed now, thanks.

ryg has been at RAD Game Tools for a while now, and mentioned yesterday on Twitter that he's been doing contract work on Valve's hardware experiments. [1]

Especially of interest to HN readers is Part 3, which is about the economics of streaming anime - the ad-revenue numbers they present are shockingly low.

Yeah, this article seriously rubs me the wrong way. The tone throughout is "Rich Nerd Buys Cool Toy." And in that context a lot of the talk about the clock's "greater purpose" comes off as bootlicking.

If I were Bezos, I'd be particularly upset about what the writer puts into his mouth about the Gates Foundation and other charities - "Well, Bill Gates has already cured AIDS and malaria, so all that's left for me is to build a fuck-off huge clock!"

It's not just that - even when we're talking Warren Buffett here, the scale of the US govt is totally different. Buffett's entire fortune ($50B according to Wikipedia) would only cover a few weeks' worth of borrowing and then we're right back where we started only Warren Buffett has no more fortune. It's silly to say we should expect him to do that.

What he's saying by advocating tax raises is "I will pay more if I know that everyone else will also pay more." He's not interested in paying $XM to reduce the debt by $XM, but he would happily pay a personal cost of $XM if it meant reducing the debt by $XB.

(This is called "collective action," and it's also Groupon's business model.)
