Perhaps unusually for someone with an interest in computing, my knowledge of electricity - the driving power behind computers the world over - is sketchy to say the least. Beyond remembering which way to twist a light bulb and avoiding the temptation to stick a fork in the toaster, I'm something of a novice in understanding how this mysterious force actually works.
As a result, I was mightily impressed by Wiebetech's HotPlug device which Paul Mah recently blogged about at TechRepublic. Here's the YouTube video where James Wiebe explains how the system works:
Clever, huh? The downside is it's yet another box to drag along with you but, hey, us IT guys have got to get our exercise somewhere.
And for anyone else struggling to replace a light bulb (I'm sure there's a joke here somewhere) just remember: "lefty loosy, righty tighty". It even works with taps...in the Northern Hemisphere anyway :-)
