Versions 2.0.3 and 3.0.3 of this python package have been released today. Both branches 2.0.x (for python 2.x, x>=5) and 3.0.3 (for python 3.x) will be in sync in the future with identical features and an almost identical API. For 2.0.3 only one new function (tileBSP()) was added. Have a look here for more information….
Reading Arexx TL-500 with Python on Linux – Part II
My first script was changed a little bit to get nicer output. It can now log the raw data received from the Arexx unit (in hexadecimal form) and uses separate log files for the sensors. Sensor numbers can be mapped to other names using a dictionary. I use two TL-3TSN, one TSN-50E (long range) and…
Using KDE’s kwallet with Firefox/Iceweasel
Konqueror is a good browser, but sometimes you need to use Firefox (called Iceweasel on Debian). I discovered a plugin to let FF store its passwords in kwallet, but after installation of the plugin all passwords were gone. Fortunately you can disable the plugin and the old passwords are still there. So if you want…
Reading data from the Arexx TL-500 on Linux
Some days ago I was looking for a temperature monitoring solution for some rooms and 19″-racks at the university. The Arexx TL-500 looked promising and I bought it. Unfortunately there are only Windows drivers available. But some people already analyzed the communication protocol and hacked a simple version of a linux driver: http://www.algorithm-forge.com/techblog/2010/01/linux-usb-driver-for-the-arexx-tl-500-part-ii/ There’s even…
processing | poor man’s evolution
This is an example from my generative design class of the digi-pro project. Note: these processing sketches are based on java, the execution in your browser may be restricted or even blocked completely. Please review the security settings of your browser and your java installation if you don’t see the sketches. You need to include…
processing | Koch-curve
This is another small demo from my generative design class of the digi-pro project. It draws a Koch curve using a recursive algorithm at variable depth. The horizontal mouse position is used for the depth value. By pressing the p-key you may toggle the drawing of small point markers. The c-key will export the points…
processing | greatest common divisor
This is a small demo from my generative design class of the digi-pro project. It uses the euklidean algorithm to compute the greatest common divisor (GCD, GGT in german ) of two numbers. The mouse position (x, y) is used for the numbers. Press the keys 1, 2 or 3 to get different visualization methods…
