Here's a quick checklist of things to do after installing ubuntu. Special sections are provided for cases when you upgrade versions.

Numix theme

Install a fresh flat looking theme:

1. Install the unity tweak tool if you don't already have it: sudo apt-get install unity-tweak-tool
2. Get the theme: sudo apt-get install numix-gtk-theme
3. Use the unity tweak tool to change the theme
4. Note that the terminal theme can also be changed via Preferences -> General -> Theme variant -> Dark

Flat icons

Get some snazzy flat icons to go along with the new theme:

sudo add-apt-repository ppa:noobslab/icons
sudo apt-get update
sudo apt-get install ultra-flat-icons

Use the unity tweak tool to select the new icon set.

Software

Development

Java

sudo apt-get install git
sudo apt-get install mysql-server

Media

Clementine, VLC, Gimp

Utility

Chromium, Chrome, Skype, Dropbox, indicator-multiload, Bleachbit

Redirect port 80 requests

Add redirect from port 80 to 4000:

sudo iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 4000
sudo iptables -t nat -L

Remove redirect:

sudo iptables -D PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 4000

The above redirect command can be put into /etc/rc.local for persistence (without the sudo).

Change Apache default port

sudo vi /etc/apache2/ports.conf
Listen 8000

sudo vi /etc/apache2/sites-available/<default>
<VirtualHost *:8000>

sudo apachectl restart
