Ubuntu 13.04 – Basic Unity Interface / Desktop Tutorial
This is a basic tutorial for the Unity Interface / Desktop which comes with Ubuntu 13.04 – it should help get you up and running. Each new version of Unity (introduced in 11.04) improves on the functionality of the desktop. This tutorial reflects the way I understand and use the Unity interface. The Unity interface consists of four main parts: Panel Launcher Dash HUD The Panel The Panel is the strip at the top of the interface: The menu bar that you are used to seeing near the top of an application’s window is now displayed in the panel: There is a catch: The menus displayed in the Panel are only for the active (topmost) application window. The menus are only displayed when you hover your mouse over the Panel, otherwise, the Panel is empty. If a window is maximized (full screen), the buttons … Read entire article »

Ubuntu 12.10 – How to Lock Your Screen / Computer
These instructions are for Ubuntu 12.10 running the Unity interface. They may be the same for other version combinations, but no guarantee is made. Sometimes you have to leave your computer but don’t want to leave your session open for someone else to start using. One option is to log out, the other is to lock your session. Logging out is rather drastic and requires you to save all your work. Locking the screen allows all your work to remain as is until you unlock the screen. Keyboard Shortcut 1) Press Ctrl + Alt + L to lock your screen. NOTE: pressing Ctrl + Alt + L means: simultaneously hold down the Ctrl key and Alt key, then press the L key as though you intend to type it.

Ubuntu 12.04 Server – How to Install a GUI
This tutorial is for Ubuntu 12.04 Server. While the instructions are probably the same for other versions of Ubuntu Server (and, maybe, for other Linux Server distros), I make no guarantee. In previous versions of Ubuntu, there were small differences between the kernel used for the Server and Desktop versions. In Ubuntu 12.04, there is no longer any difference. The main difference between the two versions is that Ubuntu 12.04 Server is a bare-bones, no frills, down to the metal version of Ubuntu – which makes it the perfect version if you want to run Ubuntu but completely customize it to your tastes without the overhead / bloat of everything that goes into Ubuntu Desktop. NOTE: Ubuntu Server is a pure command line driven system – at least until you add a GUI The … Read entire article »

The Two Types of Pirate The Shameless Pirate This one knows they are stealing your content, feels no remorse and usually does it to either increase traffic (and revenue) on their site or increase their (perceived) credibility / expertise. Some do it for both reasons. Often times they will retouch your article (and usually butcher the text) … Read entire article »
