The Google Code Jam is a programming competition where you have to solve
algorithmic problems using whatever programming language you like.
The stats of what programming languages were used in the first round
were collected:
http://www.go-hero.net/jam/11/languages
Some select figures for languages used to solve the first question:
C++ 5032
Java 2321
C# 628
C 532
Haskell 100
Clojure 13
GO 13
D 5
Scheme 5
(In previous 3 years, D had between 2-4 entries for the first question,
so not much change, despite total contestant counts increasing quite
dramatically)
Generally, I believe people tend to use the language they are most
familiar with, and for people that know more than one language they will
choose the one that is most expressive. Stability of implementations
could also be an issue.
Obviously you can't draw too many conclusions from this alone, but more
data is always better. Take what you will from it.
