Programming Languages Popularity Index

Ever wondered which programming languages are hip these days? Or what are the trends? Or whether C++ is being replaced by Java? I've just found this website from Holland which calculates index for those.

Check it out: TIOBE Programming Community Index

Very interesting way of calculating it:
"The TIOBE Programming Community index gives an indication of the popularity of programming languages. The index is updated once a month. The ratings are based on the number of skilled engineers world-wide, courses and third party vendors. The popular search engines Google, MSN, Yahoo!, and YouTube are used to calculate the ratings."

And wonderful message: C and C++ are not going anywhere. :)
