Set Windows time at boot – the ultimate reference

June 30th, 2016

While preparing some 200 non-domain-registered Windows 7 systems as POS systems, we came across a couple of dead BIOS batteries.

Upside Downternet v2.0

January 3rd, 2016

I’ve always wanted to implement upside-down-ternet, but lacked the resources. But now it’s 2016 and you can make your wifi-stealing-neighbour’s web browser do all the hard work.

IP addresses for your Hetzner machine

October 23rd, 2013

We lease a couple of machines at Hetzner.de and recently, I looked to improve my initial Easy Setup manual, so I could also use the IPv4 “main” address for a virtual machine.
