"When I design software, I really try hard to make it simple."
It's kind of interesting that his approach, using essentially 1980s-era scaling technology (inetd forking a server per request, plus old-style CGI for dynamic content) has no trouble at all running these high-traffic websites on a tiny VPS.edit: Though come to think of it it shouldn't be that surprising. If that architecture managed to work at all on 80s hardware, it should scream on anything from 2011, even a VPS.
