Missing menu icons in Eclipse (GNOME)

Recently, I noticed that Eclipse (and other programs as well) is missing icons from menu items. Following screenshot best describes the problem:
Firstly, I though that this was Eclipse related problem, but since other windows are missing icons too, GNOME was to blame. With a little help of Google, I found an easy working solution.

Background and Foreground process manipulation in Linux

Most crucial aspect of modern multitasking operating systems is to understand difference between  background and foreground processes. Process is just a technical way to call a running program. When you are interacting in some way with a process (using interface) or watching its output in a terminal, you call that process the foreground process. All other processes on your computer are either suspended processes (paused at the moment) or background processes (still running, but you can't interact with them).

Migrating to Linux (Part II): Installation

Installing Linux nowadays is a simple task. However I suggest you first try it before actually installing it.
One of the most safest method is to use a Live CD. This will load linux into your RAM memory, without doing anything to your hard disk. Nothing will be copied to hard drive. Ubuntu offers Live possibility. Simply, burn downloaded Ubuntu ISO (or create bootable USB), restart computer and insert CD (or USB) during boot-up sequence. Remember that BIOS settings must be configured to allow booting from CD (or USB).
Another option, which I generally used to test Ubuntu in the first place, is to install a virtual machine emulation software, like VMWare. This will allow you to emulate whole new machine inside your Windows environment for testing. I recommend using this method because you can see how OS installation procedure will work. If something fails, it will be only inside virtual machine, without any consequences yo your own computer. Keep in mind that VMWare is commercial product. Another good virtual emulation program  is virtualbox. Personally, I never tried it, but many youtube how-to-do-something-in-linux uses it.
There is another option using WUBI which comes with ubuntu ISO and it is available when you insert Ubuntu disc on Windows operating systems. I never tried this, but one my friends did. It is something like virtual machine emulation with ubuntu already installed. Again, I never tried this solution so google somewhere else to see what this actually does.

Migrating to Linux (Part I)

As a programmer, I found that I needed to make myself familiar with Linux OS at some point. A year passed since I got exposed to Linux (mainly using it to publish web sites on Apache tomcat) and decided that the time has come to try it on my desktop.
Last time I encountered Linux was during my faculty days. Curiosity and general interest in something new, made me to install it as a second operating system besides Windows XP. However, intensive studies allowed very little to none time to experiment. Back in those days, Linux distributions were not very user friendly to the absolute beginner. Not to mention cruel and depressing... 
Few months ago, serious 'infection' of bad sectors on my hard drive made me to replace it  with newer, better and much much larger (talking in TBs :D). It was a perfect time to reserve some space for Linux.
