So anyone want to guess at how many different programming languages exist? And have been used at least a couple of times? I discovered the following interesting URL: http://rosettacode.org/wiki/Category:Programming_Tasks. Basically it lists a large number (>100) of different programming tasks and algorithms . You pick your algorithm, then they show you contributions coded in different programming languages. Granted there are occasionally holes in the matrix, yet it is amazing how much programming languages are similar and yet different.

Alternately you can go to the language tab on the left and look at all the algorithms contributed in that language.

Hopefully you find it useful.  —John Emrich
