Linux Nyan Cat MoTD

I’ve always had interesting or funny MoTD on my servers. Since my naming convention is based on Futurama characters, I’ve plenty of fun MoTDs. There’s a project I’m working on, the acronym of which is N.Y.A.N – so of course I’ve to create a Nyan cat MOTD! Here’s what the MoTD looks like. On a Ubuntu machine, […]

Installing Environment Modules

It’s been a while since I’ve done a proper Linux post. I found Environmental Modules a while ago, and it is an utterly fantastic idea. From their blurb: What are Environmental Modules?

Issues with the NVIDIA 285.05.09 drivers on openSuSE 11.4

I came across an odd issue today with the Official NVIDIA Drivers on openSUSE. After updating the drivers, my external monitor would keep flickering and flashing regardless of the connection used (DVI or VGA).

Installing CEGCC on openSUSE 11.4

CEGCC is an a open source cross compiler for Windows CE. You can develop on a PC, and create apps that run on a WinCE device or a WinMo phone. After moving hard drives I noticed that I had forgotten about the cross compiler, which is in /opt/ – therefore not covered by a package […]

Breaking WEP using Backtrack 3

I had a bet with a friend of mine (for a case of beer) that I could crack a fake WEP encrypted access point in under 5 minutes using my rather old Packard Bell Easynote Skype Edition. There are a few things to note, I used an old WEP only router that I was about […]
