The "Mom software modification"
My Dad (interesting guy: in his mid 80's and still a member of the US National Academy of Sciences) called with the bad news: my Mom did not like the way food ingredients were showing up on the KBrecipes.com knowledge-intensive recipe web portal that my wife and I are working on.
Apparently my Mom did *not* like seeing "0.5 cups" instead of "1/2 cup".
Fortunately, I did not have to change anything in the model or controller layers - just one small bit of code in my presentation layer had to be changed.
BTW, for people interested in artificial intelligence: check out the "AI agent" page at KBrecipes.com.
