Earlier this month I was contacted by a DevCon presenter asking permission to include some slides from my eleven-year old anchor/buoy materials as part of his presentation. I said I’d be honored, but then added, “You might mention that I haven’t used A/B on a new project in about eight years.” He asked what system I was using instead, and a number of other colleagues have wondered as well, which brings us to the topic of today’s article.










As it happens, there is a very simple formula, 2^x, where x represents the total number of objects, for counting all possible combinations (including none).
