Handling server configurations
1. IntroDuring my work as a programmer I often encountered that configuration and infrastructure files only lived on the servers they belog to. If they had a copy in git, the states would always divert over time. One reason for this diverting is that you actively have to put the changed files in git, after you finished your work. It’s simply a thing you can forget. What do I mean by " Continue readingSwitching to Hugo
If you see this post, my wordpress blog is gone. My Blog now uses Hugo. I really like formats like Markdown and AsciiDoc. These formats are expressive and you can edit them with every editor you want and don’t need expensive licenses, like for Word or similar.

Ubuntu: automatic password for second encrypted disk
I just encountered the problem that I have to type two passwords at startup, for two encrypted disks. My first disk is encrypted through the Ubuntu installer. After some searching I found the perfect solution for that task. In German its called "Schlüsselableitung", in English derived keys. But perfect solutions often have a big issue why they don’t work, like here. I’m using Ubuntu 16.04 which uses ´systemd´, and that has problems with derived keys. So I found the second most perfect solution for me, using a key-file. Some people argue that this is a security issue, but the derived key is also obtainable with root rights, just like a key-file. And by the way, your private keys of your certificates are also stored on that disks and nearly nobody complains about that.
