Tiobe Programming Comminity Index for January 2005

January Headline: PHP Awarded Programming Language of 2004

The TIOBE Programming Community index gives an indication of the popularity of programming languages. The index is updated once a month. The ratings are based on the world-wide availability of skilled engineers, courses and third party vendors. The popular search engines Google, MSN And Yahoo! Are Used to Calculate The Ratings. Observe That The TPC 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.

Legend

Some Column NEED Extra Explanation:

(Position). This column indicates the difference in position with respect to last year. Ratings. The search query ' " programming" -tv' is used to calculate the TPC Index. This query is executed for the regular Google, MSN, and Yahoo! web search and the Google newsgroups for the last 12 months. The formula that is applied is # (normalized Google web hits) # (normalized MSN web hits) # (normalized Yahoo! web hits) # ( normalized Google newsgroup hits). The term "normalized" means that the sum of all web hits of the first 50 languages ​​for a query is taken and evenly distributed. (ratings). This column indicates the changes in ratings for the last 12 months. Status. Programming languages ​​that have status "A" are considered to be mainstream languages. Status "A-" and "A--" indicate that a programming language is inbetween status "A" and "B". From a supportability point of view , IT IS STRONGLY Advised to Stick To Mainstream Languages ​​for Industrial, Mission-Critical Software systems. If a programming language has a rating that is higher than 0.7% for at least 3 months it is rewarded status "A". The first two months the programming language will receive status "A--" and "A-" respectively. The Opposite Holds for Languages ​​That Go from Status "a" to status "b" .Sending US Artefacts or ideas how to improve the Way the TPC Index IS CALCULATED Are Very Appreciated (tpci@tiobe.com).

January's NewsFlash

BROUGHT to you by Paul Jansen

In order to minimize fluctuations of the index, www.msn.com is now also used as a search engine to measure programming language popularity. Both C and Java take most advantage of this change, whereas PHP loses a couple of percents. PHP has earned the title "Programming Language of the year 2004" with a positive delta of more than 3 percent within 1 year. The launch of PHP version 5 is generally regarded as a further step to maturity. It is expected that PHP will be capable to maintain its top 4 position for a long time. suprisingly, C is runner up thanks to the addition of MSN.com as an extra data provider. Delphi and Python are third and fourth best respectively. We asked Bruce Eckel (author of 'Thinking in Java' .) why Java dropped so heavily this year His answer can be found at his weblog:. http://onthethought.blogspot.com/2004/12/java-slipping.html Most interesting are the comments of Benjamin Ferrari stating that "[ ...] One Reason for Java Slipping Could Be That IT IS Not Treat ed as a 'language for everything' anymore. ". Finally, FYI. We started monitoring the programming languages ​​AppleScript, BCPL, Oberon, Occam, and Slate. We stopped keeping track of A , REALBasic, and Rebol.Frequently Asked Questions
