Cohesion tells us how narrowly defined an object is. An object with high cohesion is defined for one purpose and it only performs that purpose. An object with low cohesion tends to try to do a lot of different things. Cohesion also tells us if too many objects are attempting to do the same thing. […]

…that it will help you be successful at the #1 job in America
If you read my About page, you will see that when I choose Computer Science as a major I did so because I enjoyed it — NOT because I thought it would be a good career move. In fact, I was […]

Back in my days of playing Star Wars Galaxies, I was Ichiir, the wookie — renegade mayor of Tusken’s Bane. We had organized quite a community of players in those days and through that organization we were able to do some unique and innovative events. One of those events was called “The Hunt for Neutron-7″ […]

Ok, so this is a bit out of order, but this was the original brainstorm thread. I continued it with the thread in the earlier article. In this thread, we hadn’t come up with the name “Night City Rules” — we were still calling it the meta-game.
Sonjaya:
So, what is the meta-game? Before I can […]

If you only take away one thing from this series, take this:
DO NOT design for reuse. Design for loose coupling, high cohesion. Do that and reuse will happen on its own.
I have seen many projects go stray because the developers were too focused on designing reusable objects. They ended up creating overly complicated class […]

In the early portion of 2005, I attempted to purchase Cyberpunk CCG. We were going to integrate online and offline play via a system we were calling Night City Rules. I have included the brainstorming discussion thread here. Its a long one:
