Looked at the current November 2008 TIOBE programming language index, found via Cedrics Twitter. Java still on top, very slow slide, Ruby down by 2 places, no longer under the Top 10, C++, C# and especially Python up, PHP still 5th, Erlang at 31st, Scala at 43rd 😉 F# not listed in Top 100.
Other interesting tidbits:
"The object-oriented paradigm is at an all time high with 57.9%. The popularity of dynamically typed languages seems to be stabilizing."
Object-Oriented Languages 57.9% +1.6% Functional Languages 2.6% +0.4% Statically Typed Languages 60.0% +1.2% Dynamically Typed Languages 40.0% -1.2%
(after some big increases for dynamically typed languages since 2002)
