TITLE: We Need a Course on Mundane Data Types AUTHOR: Eugene Wallingford DATE: June 08, 2017 12:10 PM DESC: ----- BODY: Earlier this month, James Iry tweeted:

Every CS degree covers fancy data structures. But what trips up more programmers? Times. Dates. Floats. Non-English text. Currencies.

I would like to add names to Iry's list. As a person who goes by his middle name and whose full legal name includes a suffix, I've seen my name mangled over the years in ways you might not imagine -- even by a couple of computing-related organizations that shall remain nameless. (Ha!) And my name presents only a scant few of the challenges available when we consider all the different naming conventions around the world. This topic would make a great course for undergrads. We could call it "Humble Data Types" or "Mundane Data Types". My friends who program for a living know that these are practical data types, the ones that show up in almost all software and which consume an inordinate amount of time. That's why we see pages on the web about "falsehoods programmers believe" about time, names, and addresses -- another one for our list! It might be hard to sell this course to faculty. They are notoriously reluctant to add new courses to the curriculum. (What would it displace?) Such conservatism is well-founded in a discipline that moves quickly through ideas, but this is a topic that has been vexing programmers for decades. It would also be hard to sell the course to students, because it looks a little, well, mundane. I do recall a May term class a few years ago in which a couple of programmers spent days fighting with dates and times in Ruby while building a small accounting system. That certainly created an itch, but I'm not sure most students have enough experience with such practical problems before they graduate. Maybe we could offer the course as continuing education for programmers out in the field. They are the ones who would appreciate it the most. -----
