Start up tmux with custom windows, panes and applications running
#!/bin/sh
#
# Setup a work space called `work` with two windows
# first window has 3 panes.
# The first pane set at 65%, split horizontally, set to api root and running vim
# pane 2 is split at 25% and running redis-server
# pane 3 is set to api root and bash prompt.
# note: `api` aliased to `cd ~/path/to/work`

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

Sass/Less Comparison

In this document I am using Sass's SCSS syntax. You can choose to use the indented syntax in sass, if you prefer it, it has no functional differences from the SCSS syntax.

For Less, I'm using the JavaScript version because this is what they suggest on the website. The ruby version may be different.
