Set Windows time at boot – the ultimate reference

While preparing some 200 non-domain-registered Windows 7 systems as POS systems, we came across a couple of dead BIOS batteries. Time on these machines would start 1-1-2009 every time and while you could forcibly setup the correct time by pushing a couple of buttons inside of Windows, the question arose if it would be possible…

Upside Downternet v2.0

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.

Securing your server with Syslog-ng

There are many programs that help you secure your servers. There are simple firewalling programs and there are complex network intrusion detection systems. Depending on your demands, there seems to be a solution for everyone. Unless you’re picky and you think you can do better – like I did, when I wrote my own combination…

Knoeien met de cijfers van het CBS

Het Centraal Bureau voor de Statistiek doet zijn onderzoekjes anno 2010 nog steeds met een Windows-programma: u moet Microsoft Windows gebruiken om de door het CBS gevraagde gegevens te verzenden.
