License count is made by ssh'ing to surfer, then cd /home/httpd/FreeSurfer/customers, and each ???? and ????? file is a license. To license count by year, ex. 2011:

ls --full-time * | awk '{print $6}' | grep 2011 | wc -l


Mailing List

last updated 24 may 2011

There are 1232 freesurfer mailing list subscribers who actively receive emails.

To determine this number, login to the administrative interface of the freesurfer mailing list, click 'Membership Management', and the total number of users is shown italicized in the middle. This number includes those who have opted to not receive the mailings. To subtract who has opted to not receive emails, each of the 20 or so pages of the membership list must be checked (tedious, but this takes about five minutes, versus trying to figure out how this info is stored in the bowels of the mailing list server).

Where the lines are defined by the number of carriage returns. The number of lines of every page in the wiki is in PageSize , which is imported to a spreadsheet and the second column is summed*. Note that the the PageSize of any moinmoin wiki shows the number of bytes of each page. To change it to the number of lines, the wiki engine (Python) is slightly modified.

ssh fsurfer@surfer
cd /var/www/moin/wikis/fswiki/lib181/python2.3/site-packages/MoinMoin/

edit Page.py . In the size() function, comment out the line

            return os.path.getsize(self._text_filename(rev=rev))

and add these two lines

            f = open(self._text_filename(rev=rev))
            return len(f.readlines())

* - To sum the columns, paste the PageSize page to a text file and use awk to sum.

$cat pgsize | awk '{ SUM += $2} END { print SUM }'
