Setup new Mac with OSX Lion from scratch

These commands are good as of 2011-07-27.

Install Xcode 4

The download/install takes a while so start it first. When it finishes downloading you will still need to run it to complete installation.

iTerm2

Really the nicest choice for a terminal on OSX right now, especially with Lion style full screen support.

[2] pry(main)> test_string = "/foo/bar/bah/bing"
=> "/foo/bar/bah/bing"
String#starts_with?

[3] pry(main)> Benchmark.realtime { (1..10000).to_a.each { %r{^/foo}.match(test_string) } }
=> 0.009987447
