When our users load a module from the list at http://rc.fas.harvard.edu/module_list we increment the count in a MySQL database.

Afterwards, we can query the database with checkmodule as described at http://blog.jcuff.net/2012/07/part-two-scientific-software-as-service.html

[jcuff@odyssey ~]$ checkmodule -u jcuff | head
