SWT fix for Java Protocol Analyzer

Hello Folks,

I am currently working on some reverse engineering of wireless protocols of home automation systems, and sooner or later you encounter the point where you need some kind of protocol analyzer to understand what the devices are exchanging in their communication. More infos on that will follow some time later, but now I would like to share a short advice/fix for a tool I found. It is called “Protocol Analyzer” and right, it can be used to understand the signals the devices are exchanging.

Android on Acer Iconia W500P Tab

Hello Folks,
today I would like to share some interesting facts about Android on a Acer Iconia Tab W500P. I happen to have access to such a Tab today. On this Tab there is Windows 7 installed by default. Hmm, and Windows 7 is not a operation system optimized for touch input, in my opinion.

Hello my dear followers,

I am very proud and pleased to announce, that my blog was read from people of 142 countries during the year 2012. Most of them came, because of my post on how to download apk files directly form the Android store … well, yeah, you are very welcome if my work was helpful for you 🙂

I also wanna say thank you, for the about 40 visitors of my blog every day 🙂 I have never expected that my pure technical writings do attract so many readers each day, although I do not publish so many posts.

For more details, and for those of you how are interested, I would like to share the annual report wordpress created for my blog. I do hope that those of you checking regularly on my site spread the word and let me know in the comments what you liked or disliked. Please be aware, that I cannot answer to each of you comments but I do my very best.

Meanwhile you can have a look at the annual report:

Panels in Ubuntu 12.10 Gnome Classic

Hello fellows,

during the last two day I spent my leisure time to set up the current Ubuntu 12.10 on my laptop. I used Ubuntu 10.04 LTS for quite a long time, but now I backed up all my files and installed the latest version. I liked Ubuntu 10.04 a lot, the Gnome 2 Desktop was very handy and the nice graphic features were awesome. I had the 3D cube to manage my four workspaces and the wobbly window effect, so basically the nice things you can easily set up and use with Compiz.

The latest version of Ubuntu comes along with desktop manager Unity, which I don’t like very much. All the known features are gone and it is more clumsy to handle.

Here I would like to write about what I did to get the Gnome 2 feeling I am used to from Ubuntu 10.04 back to Ubuntu 12.10.
