Linux and Networking: Too Much Fail for One Configuration
So, this is a problem that I’ve spent a day or so working on at work, and it goes like this… A router (Linux, running ZeroShell) is configured with three interfaces, as shown in the following diagram: In this case, the network has a configuration problem in that PC1 is configured with a default gateway […]
Engineer to English Translation Guide
A colleague of mine (thanks Carole!) remarked the other day how I should make a T-shirt with a translation guide that roughly equates what and engineer says with what they mean and/or what one can expect out of the next series of events. I thought this was a great idea, and came up with not […]

Well, I bought and installed a shiny new WD 1.5 TB hard disk this weekend, and I have to say it went better than expected, despite the fact that it took a day to complete. The physical installation, of course, was a piece of cake (one of the great things about SATA). No messing about […]
