Running redis using upstart on Ubuntu

I've been trying to understand how to setup systems from the ground up on Ubuntu. I just installed redis onto the box and here's how I did it and some things to look out for.

To install:

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

#####Copied from askubuntu's Enabling mic mute button and light on Lenovo Thinkpad

There are two possible "hardware" indicators (to show that mute is on or off):

The Power button light (green) will blink to show when mute is on The Mic mute button light (orange) will be on or off to show mute status (just like in Windows)

Solution 2 requires a patched thinkpad_acpi kernel module, and is only recommended for advanced users who know what they are doing. This is because the patch is not included by the thinkpad_acpi developers by default, (See this discussion for more details).

###Common Steps

	echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc
	. ~/.bashrc
	mkdir ~/local
	mkdir ~/node-latest-install
	cd ~/node-latest-install
	curl http://nodejs.org/dist/node-latest.tar.gz \| tar xz --strip-components=1
	./configure --prefix=~/local
	make install # ok, fine, this step probably takes more than 30 seconds...
	curl https://www.npmjs.org/install.sh \| sh

	# Mac OS X Lion introduced a new, iOS-like context menu when you press and hold a key
	# that enables you to choose a character from a menu of options. If you are on Lion
	# try it by pressing and holding down 'e' in any app that uses the default NSTextField
	# for input.
	#
	# It's a nice feature and continues the blending of Mac OS X and iOS features. However,
	# it's a nightmare to deal with in Sublime Text if you're running Vintage (Vim) mode,
	# as it means you cannot press and hold h/j/k/l to move through your file. You have
	# to repeatedly press the keys to navigate.

	REPO_URL=`git remote -v \| grep -m1 '^origin' \| sed -Ene's#.(https://[^[:space:]]).*#\1#p'`
	if [ -z "$REPO_URL" ]; then
	echo "-- ERROR: Could not identify Repo url."
	echo " It is possible this repo is already using SSH instead of HTTPS."
	exit
