Let's start slow.

First of all, most of the GUI toolkits including QT4 are set up in the following steps, and in this order.
  1. Create an application, possibly with commandline args. (If not created explicitly this 'application' thing will already exist somewhere.)

Perhaps oddly, tk was the best. QT4 was the worst. I subclassed a text editor widget and YOW! was it ever slow!! But I think we'll give QT another look and this is why.

Mount Iphone/Ipod touch in Linux
This tutorial is thanks to a request from a subscriber on the Youtube channel. The tutorial addresses the steps necessary to get the newer Apple iPod Touch and iPhone devices to mount so they can be accessed by your Linux box. Even if your Linux distribution can do this out of the box, you may find it helpful to know what is at work, so you can address the situation if something goes wrong.
