Food for thought

"I'm not against types, but I don't know of any type systems that aren't a complete pain, so I still like dynamic typing." - Alan Kay (2003)

"UNIX was not designed to stop its users from doing stupid things, as that would also stop them from doing clever things." - Doug Gwyn

"In the real world one big split is between people who use symbolic debuggers and people who use print statements." - Peter Seibel

"Seriously, use the ****** debugger." - Jonathan M. Bardin
