TIOBE Index for September 2014

September Headline: Java and C++ at all time low

Java and C++ are at an all time low in the TIOBE index since its start in the year 2001. This doesn't necessarily mean that Java and C++ are on their way out. There is still a huge demand for these programming languages. A possible explanation for this trend is that the notion of programming has widened its scope through the years. A growing number of specific fields is using programming languages to write programs nowadays. Examples are biomedical, statistical, hardware and psychological programming. These specific fields all come with their own set of programming languages that are gaining ground at the expense of general purpose languages such as Java and C++.

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. Popular search engines such as Google, Bing, Yahoo!, Wikipedia, Amazon, YouTube and Baidu are used to calculate the ratings. It is important to note 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.

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.

  1. Apart from "<language> programming", also other queries such as "programming with <language>", "<language> development" and "<language> coding" should be tried out.
  2. Add queries for other natural languages (apart from English). The idea is to start with the Chinese search engine Baidu. This has been implemented partially and will be completed the next few months.
  3. 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.
  4. Start a TIOBE index for databases, software configuration management systems and application frameworks.
  5. Some search engines allow to query pages that have been added last year. The TIOBE index should only track those recently added pages.
