I like Unicorn because it's Unix —
Eric Wong’s mostly pure-Ruby HTTP backend, Unicorn, is an inspiration. I’ve studied this file for a couple of days now and it’s undoubtedly one of the best, most densely packed examples of Unix programming in Ruby I’ve come across.
Unicorn is basically Mongrel (including the fast Ragel/C HTTP parser), minus the threads, and with teh Unix turned up to 11. That means processes. And all the tricks and idioms required to use them reliably.
We’re going to get into how Unicorn uses the OS kernel to balance
connections between backend processes using a shared socket,
fork(2), and accept(2) — the basic Unix prefork model in
100% pure Ruby.

Python is Unix —
Jacob Kaplan-Moss does the prefork echo server example from my Unicorn is Unix piece in Python. Awesome. Let’s see some more of these. Where you at, Perl?
