Doing A/B Testing? Read This

This article claims that "MOST WINNING A/B TEST RESULTS ARE ILLUSORY”. I agree.

Please ignore the well-meaning advice that is often given on the internet about A/B testing and sample size.
For instance, a recent article recommended stopping a test after only 500 conversions. I’ve even seen tests
run on only 150 people or after only 100 conversions [5]. This will not work. The truth is that nearer 6000
conversion events (not necessarily purchase events) are needed.

and

Almost two-thirds of winning tests will be completely bogus. Don’t be surprised if revenues stay flat or even go down after
implementing a few tests like these.

From Dental Technician to Board Game Designer

Here’s a profile of Klaus Teuber, who left his unhappy life as a dental technician after creating the most famous and successful board game of recent decades.

Pete Fenlon, the C.E.O. of Mayfair Games, said, “Our volume of sales will be such that, over time, [Settlers of] Catan could, in terms of gross revenue, be the biggest game brand in the world.”

I’m a big fan of the game. I’ve bought it in 3 languages and I’ve also bought the iPad version.

How Not To Implement Card-Shuffling Software

This one is a classic, from 1999. I like it. It illustrates the value in openly publishing critical sections of highly important code:

Poker is a card game that many people around the world enjoy. Poker is played at kitchen tables, in casinos, and cardrooms -- and more recently, the Web. A few of us here at Reliable Software Technologies play poker. Since many of us spend a good amount of our days online, it was only a matter of time before some of us put the two interests together. This is the story of how our interest in online poker and software security mixed to create a spectacular security exploit.
