Heh, would be a great way for us, newbies, to learn about the specific requirements of FDS too. That could serve as guideline for us. Other aspects can be learned by hacking the code, studying the protocols, etc. But this only can be learned through experience, the hard way by screwing up yourself, or by learning from other people's experience (which I hope to learn more from this list). This is what I found most lacking. Everyone seems to have to spend a lot of time, repeating the learning process the hard way, because there is lack of sharing of case studies and past experiences. Two of my high school classmates are studying architecture and civil engineering. They have all kinds of case studies, experiences, past failures and successes. And very detailed besides that. You can easily use them as guideline for new designs. Some are no-no, some are best practices, etc. They were laughing at what we call "software engineering", because they can easily prove at what load their bridge will crash, but I have no way to prove at what load my server will crash. Sure, it is easy to say that computer and software evolve much faster, but still, this domain seems to be characterized by the lack of rigorous and scientific measurement. No, I'm talking about the O() thing, that's nothing compared to other engineering fields. I study the linux kernel too, and there's also no way to prove the reliability of the system. Sorry that this has nothing to do with FDS, and sounds like a rant :) I love my field of study, but that does not seem to stand up to scientific review. Oh great, I just flamed two groups of people in one shot :) Ah, should go to sleep now, maybe tomorrow will be better. sz __________________________________ Start your day with Yahoo! - Make it your home page! http://www.yahoo.com/r/hs
