Naive Recursive Implementation

Fibonacci numbers are used as a very common example for teaching recursion. fib 0 = 0 fib 1 = 1 fib n = fib (n-1) + fib (n-2)

How to configure the font size of views in Eclipse on Linux

Eclipse does not give you the possibility to change the font size of the views like 'Project Explorer' or 'Servers', which looks ugly on Linux since Eclipse uses the default (desktop) font size. But you can edit specific configuration files to get the proper font sizes. To fix this annoying font si...
