Where technology and lunacy meet


  • Change ip address from the command line

  • In my work I have to connect to various equipment that uses different IP addresses in order to configure and monitor them. To make it easier for myself I have made a couple of script files so that I can change the IP address easily.

    The first step before we can create the script file is finding the network adapter name. Don't worry. All we need is included in the Windows system.

  • AUR packages

  • After I bought a new printer I needed to install the printer driver for it. Unfortunately I could not make the package, that already existed in the aur, work on my PC.
    Therefor I took my other printer driver PKBUILD and changed it to install my new printer driver.

    Instead of uploading it to the aur and create a duplicate package (sort of), I decided to include my aur packages on my own homepage. They can conveniently be found on the downloads page.

  • The New Year is almost here

  • Happy New Year everyone!

    It's almost time. Get together with your family and enjoy a relaxed evening.

  • Backup using rsync

  • Making a backup is a must. And although doing it manually works, it is far from perfect. What if you are busy one week and can't run your backup?

    And then there is the question about what method to use. Do you go with a commercial solution? Or one of the free alternative systems?
    Why not go outside your comfort zone and use a standard tool?

    Well that's what I thought anyway...

    Let's first take a look at the actual script:

  • Change language on Windows 7 Home Premium

  • Unfortunately Microsoft does not support changing the on-screen language on the "smaller" versions of their Windows operating system.

    Fortunately there exists a third party tool that can handle that. It's called vistalizator and can be found on here.

    There is a pretty good guide on how to use it too. I used it succesfully on a colleagues PC to install his native language.

  • Bridged network

  • For virtual hosts it's necessary to make a bridged network adapter. At least if you want your hosts to be on the same network as the rest of your machines.

  • Static and virtual IP address

  • To set static IP address on debian (or derivative distros) is straight forward. A workstation don't necessarily need to use static addresses, but it's unavoidable on a server.

  • Samba Guest User

  • I ran across a mailinglist with a post about the "map to guest" parameter. It describes it rather well.


    samba defaults to "never" which the developers believe is a good idea.
    however, i believe the default for NT4 is "Bad Password". would it not
    make more sense to make the default the same as NT4 as most of the other
    options do?

  • Barcode Scanner Emulator

  • Concept

    Build primarily as proof of concept and because I found the challenge interresting, this little unit is able to send an ascii string terminated with a CR/LF via a RS232 connection. It's emulating the transmission of a barcode and can be used with any kind of equipment that is expecting a barcode.

  • Securing Arch Linux

  • This is the first draft of the article that later was added to the arch linux wiki. For an updated version you should look there as well.
