When I look they are ads for buying Maple. (Remember where I work). Google is smart... Much better ads than the random weblog ads I had before, although I just don't think any of my visitors are likely to want to buy a copy of "Maplesoft 9" (P.s. it's Maple 9, and 9.5 is out now....)
Work is interesting. Though I get the feeling I'm not quite earning my pay yet. Though it is only the 2nd week, I'm sure they'll eventually get me doing useful stuff.
Although spending the afternoon making a simple Maplet all fancy and doing some IM over e-mail is fun too...
