Many fans of the Zabbix monitoring software wonder why the Debian "wheezy" release from May 2012 does not contain Zabbix any more. This became a frequently asked question so I decided to put this article up.
Do you have trouble switching the display when docking and undocking your Linux laptop? In this article I will show you how to use disper and keyboard shortcuts to do that reliably if you are using nVidia's annoyingly broken RandR-incompatible graphics driver.
Zabbix is a very complex software that takes weeks to fully understand. One of the most interesting, most complex and least documented features are escalations. They are used to define a schedule what Zabbix is supposed to do when a certain event occurs. Like waking up the system administrator or do some automatic emergency cleanup tasks.
I have just recently bought the HTC Hero phone with the Android operating system. In my life I have had a whole lot of PDAs from Apple Newton MessagePads to Psions to WinCE (unbelievable that Microsoft's crap stinks like on the first day even after ten years of evolution) to Zaurus to - now - Android. Although I was sceptical I must admit that I'm loving most everything that Google does so it's the perfect choice. And although Android is not entirely free Google at least offers the SDK for nuts. And although I had no clear intention of developing a certain application I was missing I still wanted to try at least a "Hello World". So this article is supposed to get you started with Android application development using Debian.
If you need to rename a larger number of files following a certain pattern then you will long for an automated solution. The 'rename' command helps you here that is (at least on my Debian installation) part of the Perl installation. All you need to know is the basics of regular expressions to define how the renaming should happen.
Many system administrators seem to have problems with the concepts of pipes and redirection in a shell. A coworker recently asked me how to deal with log files. How to find the information he was looking for. This article tries to shed some light on it.
After I went from analog cable TV reception to a shiny satellite dish on our roof I was facing new challenges. Like how the hell do I watch TV on my workstation now and how do I record programmes to DVD now? Luckily the watching part was a cakewalk thanks to kaffeine. The great KDE media player was surprisingly capable in helping me find my hundreds of (mostly useless) TV and radio channels pouring from the sky. And it has a timer function, a simple EPG (that really needs some love) and a recording feature for DVB-S transport streams. So much for that.
