After adding a new penguin to my zoo and moving around a few services, I had the need to re-route HTTPS traffic to a different host for doing all the SSL handling (which would then send a request back – but via HTTP on a different port). The simplest way to do this is to… Read More »
I’m a data hoarder. And as such I still have email conversations going back to 2003. To not clog up my provider’s disk space and, because I don’t want to donate all these old conversations to Google, I’ve setup my own email archive using dovecot.

My private SSH key is ancient. And thus it still was in the “old” RSA format, recognisable by the header: This never was an issue. Everything works fine. Until now. While trying out GitFinder, it just didn’t want to accept my id_rsa file and always came back with “invalid format”. I’ve also made sure to… Read More »

However, I don’t know whether it’s the dongle or something specific to the RasPi2’s USB implementation,… Read More »
There are two locations where you can define the button’s location: dconf and gconf. The dconf-method works for most of Gnome Shell and Unity. However, e.g. Chrome is using the “old” gconf-setting. dconf Install and run dconf-editor. Go to org → gnome → desktop → wm → preferences and find the setting button-layout. The default… Read More »
On my hp Spectre x360, the Ins key is only reachable via the Fn key as in Fn+PrtScr. So I wanted to swap both keys. System-wide – so not only in X (using xev). I finally found this which suggested the following procedure:
Steam has the bad habit to not run after upgrades of the Steam software. This is, because it uses its own libc which expects libraries not there in Ubuntu. To fix this, delete the file libstdc++.so.6.0.18 from the following folders: Update October 2016 It seems Steam has a few more bad duplicates to make it… Read More »
To install Puppet on CentOS 7, you can basically follow these instructions. Notes: To permanently switch from WEBrick to Apache, configure systemd like this: Install client agent on RedHat/CentOS
Detect new disk size With virtual machines (VMware at least), you can resize the disk drives without restarting the VM itself. After doing that, you have to get Linux to recognize the new disk drive size. Use one of these (found hereand here) – assuming the modified drive is /dev/sdc: Check the success with fdisk… Read More »
