For instance the latest ranking for Pascal, Fortran and Ada are: Tiobe ranking -------------- Pascal 0.603% Fortran 0.563% Ada 0.376% Now, I spent a few minutes to look at the figures myself, following the famous citation "The only statistics you can trust are those you falsified yourself". So I made the search engine queries as described there: http://www.tiobe.com/index.php/content/paperinfo/tpci/tpci_definition.htm including 1-year time windowing when available. Here are the results (the simple queries without time windowing give similar results): Google Google Blogs MSN Yahoo! Wikipedia YouTube ------------------------------------------------------------------ Pascal 2'020'000 25'027 3'170'000 25'200'000 1'664 232 Fortran 1'510'000 11'768 1'640'000 7'900'000 949 113 Ada 2'140'000 110'310 2'670'000 49'300'000 1'764 70 With the weights being 23% for each engine, except YouTube with 7%, it is obviously impossible to have Ada's ranking that is lower than Fortran's and even than Pascal's. Funny thing: the weights sum up to more than 100%, so don't forget to divide by the sum of weights! If you take for instance Pascal's ranking as a reference, the rankings would be actually the following: Pascal 0.603% Fortran 0.294% Ada 0.668% <- uh-oh, almost the "A" category... Of course the reference (here Pascal) would need as well a re-ranking, up or down, which would influence Fortran's and Ada's - this would mean to gather the full index data! Did I miss something ? Some "soft factors" ? I have an Excel sheet for those interested. Or should we bug TIOBE about their statistics' quality ? Or publish a fair, transparent index based on the TIOBE idea, but with the publication of the figures ? ______________________________________________________________ Gautier's Ada programming -- http://gautiersblog.blogspot.com/ NB: For a direct answer, e-mail address on the following web site: http://www.fechtenafz.ethz.ch/wm_email.htm
