Earned Lessons

I have a new post up at blog@CACM, “How Much Software Testing is Enough“, about the value of Test Driven Development and the benefits of testing even when you don’t feel you have the time to do it well.  Included with this post is a vignette of one the most memorable bugs in my career as a software developer since it happened on a memorable date and the poetic justice from the book that triggered the problem.
