XSLT is actually a rather nice language for when you want to transform XML things into other XML things. Now, if only XML itself were nicer to write in the first place...

Abandoned VASP building near Congonhas airport (CGH/SBSP), São Paulo; pictures taken during a work trip a few months ago. An eerily serene monument of the past, quietly decaying amidst of one of the country's busiest airports.

Implementation is very silly, it uses PortAudio's synchronous interface and effectively limits the speed of the emulated machine. I've tried an async implementation on a ring buffer overwriting samples regardless of whether they've been drawn, but that just looks jittery. There's only so much you can push though an audio interface. Maybe there's a way to make that nicer somehow?

I've heard of some people using VGA as an analog out, setting a modeline with a tiny VSYNC/HSYNC and drawing according to how you want your signal to come out; then we'd get a few MHz rather that 48 or 96kHz, I guess.

@mcc I had picured TECO as an older relative of Emacs, had a long beard and spoke an inscrutable tongue. Nobody ever seemed to have actually /met/ them, but they heard stories. But I guess that works, too.
