Nur kurz am Rande: Der Fledermauslichtschrankenaufbau hat uns über knapp einen Monat wunderbar Daten geliefert, danach fielen jedoch nach und nach die Sensoren aus.
Das Problem: Wildbienen. Die Tiere scheinen sich wohl im Infrarot-Licht wohl zu fühlen… naja… das Experiment ist jetzt auf jeden Fall abgebrochen.
I was playing around with CoreOS in the last few days and i had a problem that the “installer” only created a 3GB GPT-label, with the problem that the backup header wasn’t at the end of my disk but at the end of this 3GB section, so I couldn’t just resize my rootfs to the full disk.
To resize the ROOT-filesystem we’ll have to move this backup data to the end of the disk:
On my server I have multiple IPv6 addresses, but I want to define that all outgoing connections should always use one specific address.
On Linux there is an option to mark an IPv6 address as “deprecated”, you can do that by setting the address parameter preferred_lft to 0. After that the address is still reachable, and you can still respond over it, but Linux will newer use it for new outgoing connections.

A few months ago somebody used the lasercutter at Dingfabrik to cut a box for a clock that shows time using words. I liked the idea so I asked for a box, and I got one.
Now… originally this should’ve been a birthday present for my dad, but the controller I built had some problems and I had no time™ and other stuff happened so yea… I basically finished this about a year later… but hey, it works!
