A friend and colleague said "I know just enough Java to be dangerous". Indeed I have no computer science training, but I had six years of Latin (the last one conversational). That allowed me to fix scripts and code, when posted in remote locations "from BK thru Bako to Baku" - respectively Bangkok, Bakersfield CA and Azerbaijan - check them out under 1997, 1998 and 1999.
Notice the play of words on this post "New book and banner ads" with "New look and banner maps" the previous one.
