No longer amazon.com associate on The Virtual Bookcase / 2020-01-03

I received a message from amazon that The Virtual Bookcase no longer qualifies as an amazon.com associate. That was no big surprise as I haven't done a lot of maintenance on the site and haven't added a lot of content in the last years.

The only serious maintenance was for the migration to the new web server where php 7.0 is the standard version. I wish to some day migrate to perl but haven't found time yet.

So I removed all amazon affiliate links I could find. This also means I can't use the amazon.com API anymore.

Looking at the number of commits per year in the code for the site gives a clear picture:

  7 2020
  9 2019
 47 2018
  4 2017
  5 2016
  7 2015
  5 2014
  6 2013
 16 2012
  5 2011
 13 2010
 11 2009
 28 2008
 25 2007
 81 2006
 53 2005
 34 2004
 52 2003
 53 2002
 43 2001

The 2018 peak was the migration to php 7.0. The scripts for the maintenance of the site have a separate repository where no real upgrades have happened in the last 10 year:

  6 2019
  7 2018
  2 2017
  3 2016
  3 2015
  2 2014
  3 2013
  8 2012
  1 2011
  3 2010
 16 2009
  3 2008
 12 2007
 22 2006
 55 2005
 13 2004
 42 2003
 32 2002
  7 2001

And to get this commits per year statistic from cvs:

$ cvs log | grep date: | awk -F"[ -]" ' { print $2 } ' | sort -r| uniq -c

Doing it at the top of the checked out tree will give the reports for all the files.
