Hard book sales need not indicate growing popularity of a language. In a way it could indicate that the language is more used in the software industry, because the typical buyer of an open source language book does it for a company project. For Python the lesser book sales I think indicates that the language is so easy to learn from the Internet and from groups like this, that there is no real need of a hard copy of a book. Also Python has more free books (ebooks) out there then Ruby.
Regarding the absolute percentage growth if language A grows from 10 packages to 15 it really means it *has* grown by 50% by itself and it is impressive. In this case the hypothetical language is real young, so growing from 10 to 15 is to be also considered as growth. There is no real way to compare this kind of a percentage *across* languages, which differ widely in their user base and code base. I think in the case of Python, PyPI is pretty incomplete. There are lots of excellent Python packages out in the wild which have not registered with PyPI. I am not a Perl monk, but I guess this is quite different in the case of CPAN which starts with "Comprehensive" as its first word anyway :) --Anand On Jan 4, 2008 4:23 PM, Indrajith K <[EMAIL PROTECTED]> wrote: > Number of packages to a good extent can be taken as a indicator of the > reach of the language (though it makes sense more to languages like > python, perl, ruby etc).
