Sage Downloads - Spring 2009 Edition

This post is about Sage download statistics. It is not really exact science, but good enough to measure tendencies. It uses JavaScript on all download pages of the mirror sites and tracks clicked download links by assigning them certain values. Therefore, it misses those situations where somebody downloads "directly", uses wget, has JavaScript disabled or scripts blocked. So, the actual numbers are higher. Said that, here are the numbers for April, March and June 2009:

Total Downlods:

Apr 5, 2009 - Apr 11, 2009	1110
Apr 12, 2009 - Apr 18, 2009	964
Apr 19, 2009 - Apr 25, 2009	1082
Apr 26, 2009 - May 2, 2009	1197
May 3, 2009 - May 9, 2009	1005
May 10, 2009 - May 16, 2009	1001
May 17, 2009 - May 23, 2009	1160
May 24, 2009 - May 30, 2009	1169
May 31, 2009 - Jun 6, 2009	1298
Jun 7, 2009 - Jun 13, 2009	1212
Jun 14, 2009 - Jun 20, 2009	970
Jun 21, 2009 - Jun 27, 2009	1079

There is no clear tendency, maybe a bit more at the end of the semester but falling since the end of it. Day-to-day stats are rather linear, too.

No surprises here, Ubuntu leads them all, then Fedora and Debian. Linux 64bit looks the same.

It would be interesting to score them against some index, like, population, GDP and similar. And then fit the factors to understand, why Brazil is next to China for example ...
