I just bought a Cube U30GT Android tablet, based on the Rockchip RK3066 ARM chipset. Here are the instructions to root it under Linux. (more…)
There are many programs that help you secure your servers. There are simple firewalling programs and there are complex network intrusion detection systems. Depending on your demands, there seems to be a solution for everyone. Unless you’re picky and you think you can do better – like I did, when I wrote my own combination of syslog-ng and Linux iptables, skipping the middle man.
Het Centraal Bureau voor de Statistiek doet zijn onderzoekjes anno 2010 nog steeds met een Windows-programma: u moet Microsoft Windows gebruiken om de door het CBS gevraagde gegevens te verzenden. Dat levert een statistische vertekening in de cijfers op (“gebruik van open source software”); erger is het, dat het dataverzamelingsprogramma zo lek is als een mandje. (more…)
When I started using MFOC, from a the description (in Dutch) at ov-chipkaart.org, I immediately ran into the problem described here. A bit strange seemed, that reading the card sector after sector with 10 different predefined keys did not crash the reader, while immediately after starting to try to calculate new keys, the reader would crash.

In part one we built a kernel module and put it somewhere in the filesystem. In this part, we’re going to tell the inputattach utility what to do with it.
A couple of months ago, I bought a Walkera Dragonfly #04, just for fun. While actually flying an RC helicopter is great fun, sometimes you will want to use a simulator. As Linux is my platform of choice, I tried using the Walkera transmitter with a serial cable to run a heli-sim. I found out how to do that; here’s the results of my quest. This article will be split in 3 parts: kernel; utility; Heli-X. This is the first part.
I will use Ubuntu Linux 8.04 Hardy Heron for my explanation. You can use other versions of Linux – but please beware, you will need a pretty recent kernel to be able to build the kernel module.
