I just installed another language to Ubuntu 12.04, and was a bit surprised not to find any icon in the systray (taskbar, top bar, notification area), also there was no shortcut I could find to make it change language.
In case you are trying to change the keyboard layout/language with a keyboard shortcut or setup the systray icon that looks like a keyboard to switch the language in the notificationa rea, then you've come to the right place

When I started programming website on a localhost, I often ran into issues setting up SEF URLs. So, I started using virtual hosts by creating fake domain names and then make them connect to the local apache server via the hosts file.
For example, if I work on webdesignblog.asia on my localhost, I am accessing webdesignblog.dev, which is a fake domain linked to my localhost via the virtual hosts (enabled sites) and hosts modifications.

Whaaa, Datageddon! My 2TB external just decided to stop working. "dmesg | tail" gave me the worst of the worst messages: "EXT4-fs (sda1): group descriptors corrupted!", which translates to me as "kiss your data bye bye"…
After some searching I came across the magic terminal commands to solve the problem:

After performing a quick search on how to manipulate an existing VDI file, I found a bunch of lengthy guides, all pretty much saying the exact same thing… create a new VDI, load the old and new VDI disk images into a Virtual Machine as a master and slave drive, boot with a gParted or equivalent BootCD image, and then clone the old disk to the new one… or in short: do a lot of steps that take forever, but not what I want: Resize VirtualBox Disk Image.
After flipping through the 10th or so guide, I realized that pretty much all of them were written in 2008… very unusual as bloggers usually write about the same subject on a yearly basis. That in mind, I search a bit more and… BINGO! Since VirtualBox 4 is out, there is a simple command line tool to resize VDI images. Man, those extra 5 minutes of searching just saved me from a lot of hassle and a huge waste of time.

I configured the wifi settings of the printer using the USB connection, a Windows PC, and the Windows portion of the Installation CD provided with the printer. After it was configured, I disconnected it from the USB, so there is only the power cable now.

During an update some package broke and caused apt-get to throw a fit. I could't remove the package, nor could I update it. It was really annoying, as no update would work, as long as this broken package was there.

This guide on how to resize a software raid1 should work on most Linux Distributions. I used a dedicated server located in Strassburg running Ubuntu Server 12.04, and I connected to it via ssh from Asia. 
Here my setup prior to doing this:
Two 2 TB hard disks (sda/sdb) with 3 partitions each
sda1/sdb1 -- md0 -- /boot
sda2/sdb2 -- md1 -- swap
sda3/sdb3 -- md2 -- /
md2 uses pretty much all the space.
Here the setup after completing the steps below:
Two 2 TB hard disks (sda/sdb) with 4 partitions each
sda1/sdb1 -- md0 -- /boot
sda2/sdb2 -- md1 -- swap
sda3/sdb3 -- md2 -- / (~320GB)
sda4/sdb4 -- md3 -- LVM "nova-volumes" (~1650GB)
