</h2><p>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 <i>best</i> programming 
language or the language in which <i>most lines of code</i> have been written.</p><p>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 TPC index can be found <a href="tpci_definition.htm">here</a>.

Based on this definition languages such as HTML and XML are not considered 
programming languages. The same holds for data query language SQL. ASP and ASP.NET are also not 
because it is regarded a technique that makes use of other languages such as JavaScript and 
VBScript or .NET compatible languages.<br><br><li><i>Q: How are dialects of languages grouped?</i><p>A: Some languages are grouped together because they are very similar to each other. An example 
is the language entry Basic which covers Visual Basic, QBasic, Microsoft Basic, etc. VB.NET is an 
exception to this rule because it differs too much from classic Visual Basic versions. The ratings 
for a collection of languages is calculated by taking the maximum of all individual entries. BTW, 
assembly languages are not grouped in the index because they differ so much from each other in our 
opinion that they should be treated separately.</p><li><i>Q: Am I allowed to show the TPC index in my weblog/presentation/publication?</i><p>A: This is OK provided that the original source is referred to: <a href="http://www.tiobe.com" target="_blank">www.tiobe.com</a>.</p><li><i>Q: What happened to Java in April 2004? Did you change your methodology?</i><p>A: No, we did not change our methodology at that time. Google changed its methodology. They 
performed a general sweep action to get rid of all kinds of web sites that had been pushed up. As a 
consequence, there was a huge drop for languages such as Java and C++. In order to minimize such 
fluctuations in the future, we added two more search engines (MSN and Yahoo) a few months after 
this incident.</p></li></ul><p class="tcopyright">Send mail to <a href="mailto:webmaster@tiobe.com">webmaster@tiobe.com</a> with questions or
