Think of it as a map of the rapidly changing world of computer software.
On Wednesday, GitHub published a graph tracking the popularity of various programming languages on its eponymous Internet service, a tool that lets anyone store, edit, and collaborate on software code. In recent years, GitHub.com has become the primary means of housing open source software—code that's freely available to the world at large; an increasing number of businesses are using the service for private code, as well. A look at how the languages that predominate on GitHub have changed over time is a look at how the software game is evolving.
In particular, the graph reveals just how much open source has grown in recent years. It shows that even technologies that grew up in the years before the recent open source boom are thriving in this new world order—that open source has spread well beyond the tools and the companies typically associated with the movement. Providing a quicker, cheaper, and more comprehensive way of building software, open source is now mainstream. And the mainstream is now open source.
Hmm, Perl has been declining...

Not insufficent, less efficient. The compiler has to have a clear view that you are doing
for( i = 10; i 20; ++i ) prod *= a[i]
and that it's the same as doing
for( p = a+10; p a+20; ++p ) prod *= *p
(which would translate to a single "repeat 10 times multiply addressed by register with autoincrement" instruction inside the loop -- those things in the core of the loops make the big difference in performance)
(notice that in most cases, yeah, the compiler can do that. But the pointer arith is there to deal with the other :D cases)

(smart people know that there is a < that was omitted above, on each code example)
