I really love Qt, so one of the first things I wanted to do is to get my Qt application running on raspberry Pi.
The QtOnPi didn't work for me, because it is using Qt5, but my apps require good old Qt 4 desktop widgets. But what I understand it is possible to port it to Qt5

It's annoying when you copy image to the SD card and the main partion uses 2Gb out of 8Gb (in my case)
Here is just a quick reminder what to do to set up arch linux on Pi while utilizing all 8Gb or whatever size SD card you have.
