When I'm typing English (or, indeed, when I'm typing code) I insert a space after every comma.
Yet today I received a sample data file that was allegedly "comma delimited" and strangely has a space after every comma.
Of course, this is easy to handle in Perl since I can just split on qr/, / instead of qr/,/, but it gives me a spooky feeling that a human is generating this data each day. I know that can't be the case looking at the mind-boggling numbers in the data, but it still scares me. Combined with the episode related in the linked previous journal entry, it gives me the certain feeling that these people have rarely created a data file for consumption elsewhere before. Not a way to inspire confidence.
