License count is made by ssh'ing to fsurfer, then

cd /home/httpd/FreeSurfer/customers

and each ???? and ????? file is a license. To license count by year, ex. 2015:

ls --full-time * | awk '{print $6}' | grep 2015 | wc -l

and this is a loop which regenerates the table data above:

@ total = 0
foreach year ( 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019)
set count = (`ls --full-time * | awk '{print $6}' | grep $year | wc -l`)
@ total += $count
echo "|| $year || $count || $total ||"
end

Mailing List

Subscribers

last updated March 1 2019

There are 2936 freesurfer mailing list subscribers (includes those who do not receive messages but can post).

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).

Monthly Post Counts

To get this data, nmr-help can get the raw message-list data from the mail server, where you'll ask them to run this, then they send you the output file 'fsmsgraw.txt':

[root@mail freesurfer]# for f in `ls -1d 2* | grep -v txt` ; do  [ -d $f ] || continue; echo $f `ls $f/*.html | wc`; done > fsmsgraw.txt

The output looks like this:

2014-May 567 567 11905
2014-November 120 120 3118
2014-October 477 477 11923
2014-September 444 444 11986

We care about the first and second column, where the second column is five greater than the message count, and where we'll want to make the first column (date) sortable. So run this:

cat fsmsgsraw.txt | awk '{printf("%s\t%s\n", $1, $2)}' | sed 's/-January/ 01/' | sed 's/-February/ 02/' | sed 's/-March/ 03/' | sed 's/-April/ 04/' | sed 's/-May/ 05/' | sed 's/-June/ 06/' | sed 's/-July/ 07/' | sed 's/-August/ 08/' | sed 's/-September/ 09/' | sed 's/-October/ 10/' | sed 's/-November/ 11/' | sed 's/-December/ 12/' | sort -n | awk '{printf("%s-%s %s\n",$2,$1,$3)}' > fsmsgs.txt

which creates output like this:

06-2014 596
07-2014 666
08-2014 557
09-2014 444
10-2014 477
11-2014 120

which can be imported into a spreadsheet, column 1 interpreted as a date, 5 subtracted from column 2, and plotted, like this:

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 exported to a text file and the second column is summed. Note that 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 }'
