GPS plasmoid

Thursday, April 9th, 2009

Having recently acquired a bluetooth GPS receiver for as little as 20 €, and just having switched to KDE 4, i tried to combine those two, and write a little plasmoid to show the current position on the desktop.

And that is basically everything to say, enjoy the little applet.

Installation

Make sure gpsd is installed and set up properly. Also make sure the python bindings are installed.
In Ubuntu you would need to:

sudo apt-get install gpsd python-gps
sudo dpkg-reconfigure gpsd
sudo apt-get install python-plasma python-dev

After those are installed, you can proceed to install the plasmoid with plasmapkg -i.

GPS Mouse in Python

Saturday, November 8th, 2008

Some months ago I aquired a cheap gps mouse (Royaltek RGM-2000, really cheap, 2 € + shipping) at ebay. My plans to use it in combination with an microcontroller and a display haven’t worked out, it is a lot of work and the garmin units do that job fine.
However, playing around with it in python lead to better results. Getting the data to google earth works nicely, and at least qlandkarte can read the generated gpx tracks.

Usage

  • Start the Program, add a parameter for the port your nmea device is attached to (/dev/ttyUSB0 is the default

kernel config based on lsmod output

Monday, October 6th, 2008

After reading about the amazing 5-seconds bootup I decided to once again compile a kernel myself. Compiling a kernel is almost trivial these days, but customizing the configuration can still be quite confusing. For example, the names of the modules in lsmod aren’t the ones you select as config options. To map them, I found some scripts in the LQWiki, but they weren’t that easily to use, and also programming in bash is just painful.

So i wrote a python variant, that takes an input config(for example your distributions config) and changes the reply to “y” for all config options if the respective module is loaded(ie. if ext3 is loaded, CONFIG_EXT3_FS=y will be set).

Feeding a screensaver from the digikam database

Monday, June 2nd, 2008

After several months of living without any screensaver, I decided it just would be nice to once again have something nice to watch and show while idling. I really like the photo slideshow that ships with windows vista, but as my laptop runs linux only that was not possible. The next best thing i found was glslideshow from the xscreensaver compilation. Like most slideshow programs, glslideshow will look into a given directory, and show files out of it in random order. However, there are downsides to that simple approach: My photo folder contains some private pictures, and also some pictures that are just ugly. So i decided to connect it to my digikam database, which was surprisingly simple.
