The idea is to list one hundred curious things about programming. These can be taken on faith. In some languages they are true. In other languages, no. Developing a sense of what might and might not be true is the part of programming that is rarely taught, probably because the inconsistency is an embarrassment.

Are we close to done? Not hardly. Let's assume we'll have 10 topic areas averaging 5 topics each with an equal number of advanced topics hidden within. This makes for 100 topics total. Our 7 topics has us about 70% done with the surface outline, 35% done identifying topics, and, just samples of the writing to test the style.
