Using multiple github accounts with ssh keys

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

  1. Generate ssh key pairs for accounts and add them to GitHub accounts.

System wide cpu usage:
The numbers on the top left from 1 to 8 represents the number of cpu's/cores in my system with the progress bar next to them representing the load of cpu/core. As you would have noticed the progress bars can be comprised of different colors. The following list will explain what each color means.
Blue: low priority processes (nice > 0)
Green: normal (user) processes
Red: kernel processes
Yellow: IRQ time
Magenta: Soft IRQ time
Grey: IO Wait time
