TIOBE Programming Community Index for January 2011

January Headline: Python wins the TIOBE Programming Language Award of 2010!

Programming language Python has become programming language of 2010. This
award is given to the programming language that gained most market share in
2010. Python grew 1.81% since January 2010. This is a bit more than runner up
Objective-C (+1.63%). Objective-C was favorite for the title for a long time
thanks to the popularity of Apple's iPhone and iPad platforms. However, it lost
too much popularity the last couples of months.

Python has become the "de facto" standard in system scripting (being a
successor of Perl in this), but it is used for much more different types of
application areas nowadays. Python is for instance very popular among web
developers, especially in combination with the Django framework. Since Python is
easy to learn, more and more universities are using Python to teach programming
languages.

The TIOBE Programming Community index is an indicator 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!, Wikipedia and YouTube are used
to calculate the ratings. Observe that the TIOBE index is not about the
best programming language or the language in which most lines of
code have been written

The index can be used to check whether your programming skills are still up
to date or to make a strategic decision about what programming language should
be adopted when starting to build a new software system. The definition of the
TIOBE index can be found here.

This Month's Changes in the Index

This month the following changes have been made to the definition of the
index:

A list of all programming languages that are tracked by the TIOBE index has
been added to the definition page.

There are still lots of mails that need to be processed. As soon as there is
more time available your mail will be answered. Please be patient.

Bugs & Change Requests

This is the top 5 of most requested changes and bugs. If you have any
suggestions how to improve the index don't hesitate to send an e-mail to tpci@tiobe.com.

Add queries for other natural languages (apart from English). The idea is to
start with the Chinese search engine Baidu.

Add a list of all search term requests that have been rejected. This is to
minimize the number of recurring mails about Rails, JQuery, JSP, etc.

Start a TIOBE index for databases, software configuration management systems
and application frameworks.

Apart from "<language> programming", also other queries such as
"programming with <language>" and "<language> coding" should be
tried out.

There is a bug in the calculation of the max of all entries in a language
group.
