Bob brought me an error message from one of the web apps I wrote for him to create capital improvement projects for public schools. The error read “Can’t do math!”   While matching rooms to the master schedule for a college, I noticed several classes were scheduled in a men’s restroom. Thinking this must be a mistake, I checked the title of the classes, which included “On site pumping methods” and various “Safety” classes. Perhaps they were scheduled in right place after all.
