Truecrypt Failed to set up a loop device in openSUSE

If you are getting the error message “Failed to set up a loop device” while mounting Truecrypt media on Linux, especially in openSUSE, there’s a simple fix. Normally I have to browse through various forums to find different bits of information to fix a problem, and I normally post the full fix here. This fix is so simple that I’ll link directly to it on openSUSE’s support forum.

Show Desktop icons in Gnome 3 on Open SUSE 12.1

Open SUSE 12.1 comes with the completely redesigned Gnome 3 desktop, which in my opinion is the best one so far. I have been using Gnome for a few years now and even though I like the clean design of Gnome 3, I still like to have some desktop icons. To Show your Desktop icons on Open SUSE 12.1 is a very simple procedure,

  1. Go to Applications > Advanced Settings
  2. Select Desktop
  3. Set option “Have file manager handle the desktop” to ON

For other Versions of Linux you may need to install dbconf

Arduino the Open Source hardware

If you are a thinker, a mad scientist in the making or just a curious ADD person like me, the Arduino boards are just what you are missing in life.

Arduino Uno BoardArduino is an open-source physical computing platform based on a simple micro controller board, and a development environment for writing software for the board.

Arduino can be used to develop interactive objects, taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors, and other physical outputs. Arduino projects can be stand-alone, or they can be communicate with software running on your computer .

Arduino hardware can be used in Windows, Mac or Linux. The boards can be assembled by hand or purchased pre-assembled and the open-source IDE (programming environment) can be downloaded for free.

There’s a great starting guide at http://arduino.cc/en/Guide/HomePage, but I have also been recommended this book:

30 Arduino Projects for the Evil Genius

This guide shows you how to program and build a variety of projects with the Arduino microcontroller development system. Covering Windows, Mac, and Linux platforms, it gets you up to speed with the simplified C programming you need to know–no prior programming experience necessary.

You can find more books and arduino boards and components on here.

Examples of what one can accomplish with Arduino:

Spotify crashes in Linux under Wine

I have been using Spotify on Linux for quite a while now, under Wine. Suddenly it decided not to work a any more.  I was getting the following error when trying to run the new 0.6.2 version.  “The program Spotify.exe has encountered a serious problem and needs to close.”

Trying to run it from the command line showed me yet another error message: “wine: Unhandled page fault on read access to 0x00000068 at address 0x7bc368b5 (thread 0042), starting debugger…”

UPDATE: Please first try the WinHTTP.dll fix posted by Nick in the comments section.

My simple solution: After searching in various forums and blogs and trying a myriad of  “fixes” that took me nowhere. The simplest answer I found was to remove the Spotify app from Facebook. I can now listen to my Spotify  play lists on my Open SUSE Linux. It does mean that you will be without the Facebook integration, which for me is not a big deal.

To delete Spotify from your Facebook account go to Privacy Setting >> Apps and Websites >> edit (Spotify) >> remove application

Spotify does have a Linux version of its software, which is currently in preview version and only available for Debian/Ubuntu  paid subscribers.  On their website they said: “As we haven’t found a reliable way to display ads yet, this version (Linux Preview) is only available to Spotify Premium and Unlimited subscribers. ”  Fair enough I would say…
