I've learned one thing. Just because some people have Ph.d's or they work for a money-rich organization, dosn't mean they have any brains. Most universities are just "diploma mills' nowadays. That said, Linux and Perl should be NUMBER 1 on the list, if you want to gauge them in terms of impact on the computing world. Just a bunch of idiots at ZD....they remind me of that recent Microsoft commercial shown during the football games.....the whole office runs around like jackasses and dumps water on some jerk, just because he got Windows to print out a report. Just the kind of employees I would want running my favorite corporation.
