A list of links that I find useful for:
Useful information can be found on the internet but it's hard to find good relevent information. For example: mv */* . will move all your files in a directory up a level. But you can also use sudo rsync -avz . /var/www/html. You can easily duplicate a database in phpmyadmin. Wireframes and rough layout for pages or a website can be done in Adobe Illustrator. But where do you get that information?
Come back for updates and a more complete listing.
