Multiplication
"Quickly, what is 1000 x 1000?"
"1,000,000."
"How did you arrive at the answer?"
"Simple. I just multiplied them together."
"You sure?"
"Of course!"
"Hmm... Now, what is 999 x 999?"
(Timed out thinking) bzzz---
"You didn't do the multiplication that time, did you?"
"Uhh... No, I didn't."
"What did you do?"
(Hang head in shame, low voice) "I counted zeroes. There are three zeroes in 1000. And three plus three is six."
Aspect Oriented Programming
Yesterday's presentation at the St. Louis Java User's Group is excellent, even though we have to move 50 people to OCI.
Mark Volkmann talked about Aspect Oriented Programming. Very thorough, very lively. The presentation material is on the Javasig website, here.
