1. Hunting Ghosts

    For one task I need to start a group of services, provided through a docker-compose.yml. It worked yesterday and today I'll finish my task with a developer's test of the complete integration.

  2. KeepassXC Browser plugin

    For years I have been using KeepassXC and in some places even as browser plugin. Its auto typing sequence is very flexibile. But a drop down selection at the input fields for username/ password is much easier to handle. But this comes at a price. More…

  5. Wonderdisk

    I often do hardware tests and compare Linux desktops. So I need many distributions bootable but also isolated. A handful of pen drives is the easiest solution. The following sections describe how to go one step further and bring them to a single USB disk. More…

  6. Power or Float-Exception

    As always nothing changed but nevertheless a common work process doesn't work anymore. Additionally it is a very simple task done in a few minutes. Pressure rises and no matter where you search for the solution it is always found where you look last. More…

  7. Mastering Gentoo

    The common desktop Linux variants like Fedora, Ubuntu or Debian have an installer that gets the average computer up and running within a few hours. Its result is an absolutely usable desktop environment. But Linux is so much more. When using Linux From Scratch, Arch Linux or Gentoo you end up touching a mirror turning your finger into liquid metal. Either panick now or see behind the Matrix. This is the first part of 4 starting with suggestions for filesystem layout. More…

  10. Finding of the Week

    I really enjoy taking part in other developer's struggles. This includes playing developer's games. One of them is the so called Finding of the Week. The intention is to educate, relief from stress and to remember the early days of programming. A group of developers comes together online. And everyone presents a piece of code and a very (geek) entertaining discussion starts. Once this turned awkward for me and implicitely many others. More…
