For anyone else, thinking hmm, that sounds easy. The TL;DR is that you don't "just need to read" Alex's blog, you need to read, think, try, fix, bug search, rinse, repeat, take on board a number of complex ideas and concepts, and/or buy ideal hardware. The arch linux topic is very long! I've read most of it as it came in, but reading that whole thing for tidbits and fixes that Google doesn't always turn up isn't quick or easygoing. Good luck!

That was 3 years ago. Right now the process is more streamlined.

Of course I assume that people that frequent hacker news are geeks and tinkerers.

Yeah, I'm definitely a geek and tinkerer, but testing in Safari is work stuff I don't like, and the only way to do it properly is with actual Apple hardware.
