Recently I've been devoting most of my spare time to (a) troubleshooting a graphics card/motherboard problem on my home PC prior to calling the manufacturer; and (b) WhaTBI?.

Unfortunately, the manufacturer in question was Multivision, who I found out yesterday ceased trading earlier this month, so the less said about that the better :(

On the WhaTBI? front, though, I've been making some reasonable progress, and hope to checkin again some time soon. Before this, though, I definitely need to get my head around the "inteface vs. abstract base class" issue. I guess Brad Abrams and the various CLR guidelines will be my first port of call, but if anyone knows of any alternative resources, or can offer any practical advice, it would be much appreciated.

Hot on the heels of this will be a bit of a look at OPath, so if anyone knows of any good introductions then again I'd be most grateful. (As an aside, someone [sorry - can't remember who now] recently pointed at this intro to XQuery, which I must also read...)

But before all that I guess I'd better get some "real" work done...
