I just want you to know that your write-up of client/server architecture and programming was the single best resource that I used when exploring that area of software development. I read Valve's, Gaffer's, and yours, dozens of times each. Yours was the silver bullet. I also appreciated your examples at the end simulating a client/server model as those were very helpful. I made a really simple game with my knowledge [0], purely for exploration and fun, but I couldn't have done it without your articles.
