According to TIOBE Programming Community Index Java is the leading programming language again, ahead of C and C++, its nearest rivals.

Perl and PHP occupy 4th and 5th positions respectively attesting to the power of scripting languages.

Within the .NET languages only C# appears likely to survive. VB has suffered large decline and is currently in 6th position.
Programming Languages

Ruby is at 28th behind DBase (didn't know people still used it).

At the moment there is a trend that both Visual Studio 6 core languages, C++ and Visual Basic, are losing heavily (-8.89% for the last year). Are all those Visual Studio 6 users moving to Visual Studio.NET? Apparently not. VB.NET and (managed) C++ are not gaining popularity. The only language that is still on the rise is C#. But that only counts for 1.7%.
