This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
I took a short look at the example chapter of PostGIS and realized, Open Street Maps is not mentioned in the book. Is this becous of, they changed to PostgreSQL only during the last year, or is there an other reason for this?
Anyway, the book looks quiet interesting, and I would be happy to read a bit more in it ;)
