Like always Tiobe Softwares has released rankings of programming languages and popularity of programing languages for the month of January 2009. 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. According to Tiobe few of the major gainer and loosers are
- Java Still topping the chart at 1, loosing a small fraction of popularity
- C is gaining popularity and is firm on 2nd spot
- C++ is gaining ground
- PHP came down one place
- ABAP is becoming popular
- Python is down one place
- Perl and Delphi goes down by one spot each
Programming languages last few months rankings:
- Popularity of programming languages for the month of November
- Popularity of programming languages for the month of October
- Popularity of programming languages for the month of September
- Popularity of programming languages for the month of August
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.
