  1. Re:But what about non-IT projects? on 95% of IT Projects Not Delivered On Time · · Score: 1
    The specify-design-build-test(maybe)-deliver process is deterministic. If it's not, what makes you think you can predict its schedule in the first place? 5% on time may be no more than dumb luck.

    Since you clearly now agree that we are speaking of a determenistic process, you also have to agree that Turings Halting Theorm applies. Thus the results of any decision the process demands may not be predictable other than by running the process. The more decisions the process demands, the less predictable they will be. The less predictable the projects path, the less likely you can meet a pre-ordained schedule of any type.

    Thus, no matter what the deterministic process is and no matter how dedicated and skilled the people executing it, the probability of meeting any particular schedule is inversly proportional (at least!) to the number of decisions the process demands.

    Of course, this assumes that you have customers who:

    1. Know exactly what they want
    2. Are articulate enough say what they want
    3. Won't change their (alleged) mind
    ...and how often does THAT happen?

    No wonder the toy projects in biz school give the pointy-haired types the idea that schedules can be met!

  2. Antiradiation missile? on How to Protect Radio Signals Over Short Distances? · · Score: 1
    The usual means to prevent unauthorized broadcasting is to have a lawyer send them a letter. Even better if the lawyer works for the FCC! However, if the short-range broadcasts meet the FCC part 15 rules (in the US anyway), you're out of luck in preventing anything.

    Beyond this, the "big boys" recognize that it is most difficult to prevent the dedicated and motivated from transmitting before the fact. They deal with the problem in two ways:

    The first is jam-resistant modulation schemes - so the miscreants will have difficulty denying authorized broadcasters access to the receiver.

    The second is by various authentication schemes, so that what ever is received can be identified as having come from an authorized source and not a miscreant.

    All of this begs the question, broadcasts authorized by whom?

  3. Orwell is at it again? on How Long Do You Want Digital Media To Last? · · Score: 1

    Hmmm... according to 1984, one of the principles of Ingsoc is "he who controls the past, controls the future." If records are less than persistant, and whoever is in charge at the time that info is copied to new media doesn't have the integrity to accurately copy all of the bits (perhaps a neo-Ministry of Truth?), hmmm... Short lived media seems to fit Ingsoc very well.
