Trusted SSL certificates used to cost money, but in the past companies like StartCom already started to hand out domain-verified certificates for free, but now we have Let’s Encrypt, which takes a different approach.

I really like IP-KVMs. They are great devices that allow you to directly connect to and control your computer from basically anywhere in the world, even if your system crashed or your network card died. Also you can access the bios settings and raid configuration utilities which wouldn’t be possible with normal remote-desktop tools.

Some of there devices also have a possibility to attach “virtual media” to your device, essentially allowing you to boot your remote system off an iso image on your local system, giving you a lot of possibilities to reinstall or rescue an operating system.

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!
