Quest for a Driver – or how to waste your Life Away
December 15, 2008 @ 3:02 pm

Last month I inherited an old laptop – an Averatec 2100 which was to be put on Craigslist and sold for a few bucks. Well, it didn’t work out that way.

jQuery and ASP.NET Article Part 2 Posted
December 03, 2008 @ 2:26 am

Also covered is client side templating for managing HTML in one place.
