calling Fortran from C

If you want to call Fortran from C, Here is a good site to consult to. Without it, I would have spent many more hours.

The web site's author is Jonathan Thornburg. Just want to say 'thank you'.

Python is overtaking Perl

Here is Python vs. Perl on Google Trends.

Something can be said from this:

• Python is overtaking Perl;
• Bangalore of India has more Perl/Python programmers than any other city in the world;
• Indian programmers prefer Perl over Python by a ratio of 3 to 1, lagging behind the world trend;
• The three most Python capable cities in the United States are San Francisco, Seattle and Atlanta.

Some Notes:

• My understanding of Google Trends is that the rankings among regions/cities/languages are by absolute volumes, but the bar lengths are not comparable, otherwise you would conclude that there are as many Swedish-speaking Python programmers as English-speaking ones.
• I tend not to trust the Regions ranking. It says that both Norway and Finland (population of less than 10 million each) have more Python programmers than the United States (population of more than 300 million).
