The diff output is more specific:
[I]f a whole block of text is moved, then all of it, rather than just the beginning and end, is detected as changed.
>The algorithm described here avoids these difficulties. It detects differences that correspond very closely to our intuitive notion of difference.
It often be helpful to be able to debug memory usage in Swift on Linux, for example to debug memory leaks.
This is a quick overview of how to generate a report of memory usage for your Swift app. This guide will only show you how to generate the report, not how to analyze it, it might be written up in a blog post later.
First we need to install a tool called Valgrind, which is used to trace memory usage.

| let end = CACurrentMediaTime() | |

Sublime Text 2 ships with a CLI called subl (why not "sublime", go figure). This utility is hidden in the following folder (assuming you installed Sublime in /Applications like normal folk. If this following line opens Sublime Text for you, then bingo, you're ready.
open /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl
You can find more (official) details about subl here: http://www.sublimetext.com/docs/2/osx_command_line.html
