Back in 1997, one of the reporters, Robert McMillan, was working for another publication when he emailed Postel about upcoming changes to the internet’s naming system. Postel responded, but only to berate McMillan for using a digital signature with his email message. The signature, he said, was just a pointless way of clogging up internet bandwidth. He never did answer McMillan’s question.
Now this makes me smile...also in 1997, after years of developing applications, I was just getting started to focus on helping customers improve performance of their application(s). A wise man, then in his late fifties, let's call him MC (I don't have permission to publish his real name), who practiced the very craft for years, pulled me aside and told me, "the only way to improve performance is to do-less-things, whether it is less number of hops, reduced DB access, less disk access, jam more data into the pipe, whatever it may be, just do less...look for waste, and there are always waste. BUT never forget the cost aspect of the change. That's the pudding. If you can remember that, you would do well in this business". And my friend I never forgot that...THANK YOU.
