Jazoon: Wednesday Keynotes

I don’t remember much from these keynotes except that Ted was great as usual and that the second keynote bored me to death. I did take some notes, though: I should have a look at Apache Sling (in incubation) and Erlang.

Ted gave some examples of simple questions which a third grader could solve but which most adults (even those with a degree) can’t solve in any reasonable time. Most needed one hour or more. One was this:

Take two sticks, one is 4 meters and the other is 5 meters. Throw them in a well which is 3 meters wide. In which height do the sticks intersect?

It took me 15 minutes to come up with 2.7 meters (or (5*sqrt(34)) / (5+sqrt(34))). Anyone?
