Ruby 1.9.3 installer for Cloud9 workspaces
#!/bin/bash
# This script downloads and installs Ruby 1.9.3-p194 into Cloud9 workspace.
# It makes possible to use Ruby 1.9 for running apps there instead of default Ruby 1.8.7
# Create this file in a root of your workspace.
# Run in command line: chmod +x install-cloud9.sh
# And: ./install-cloud9.sh
# It will take some time to download and compile libyaml and ruby.
# Adjust ruby version paths according to your needs.

Latency numbers every programmer should know

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

fix git commit with wrong email address in git config, before pushing
If:
- you add and commit with the wrong email address in git, and
- your remote has a hook set up to prevent you from pushing with the bad address
Then you need to amend the author of your commit before push can succeed:
1. fix your email address in git config:
$ git config user.name "Your Name"
