My setup for Rails dev on OS X Lion

1. Back up

   A few things to think about:

   • media
     • photos, music, and videos should all be on external drive
   • projects/code

• make sure all Git repos are pushed up

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

• rbenv
• ruby-build

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

# About:
# A flight planning algorithm, particularly useful for private pilots.
# The idea is that one might be interested in, say, flying into LED (in Russia)
# from DCA (in DC); bearing in mind that small aircraft can only go so far
# on a single tank of gas, this algorithm will perform the hard work of
# computing a rather tricky route.
#
# Concretely:
# Given a set of airports (and their code, latitude and longitude),
# find the shortest route between any given airport A and B,
