System Software
The common belief in the gambling world is related to the roulette wheel bias. Many kokodrilos (big–time gamblers) swear by the wheel in the sky that they make millions by exploiting the roulette wheel bias. There are plenty of legends. The wheels must have been terribly worn out.
I do have some problems and some remarks regarding the bias of the roulette wheel. I have done the most thorough research in this field. My tool of choice is computer software. My roulette software is not only unique, but founded on solid mathematics. I have analyzed both real–life casino roulette spins and random–generated spins. The reports are very much the same. Nobody will ever be able to tell which one is the real spin report and which one is the report on computer–generated roulette spins. The number frequencies are the same.
The three volumes systematically develop and apply the systems methodology for software development. For that the concept of a system is analysed and various types of systems used in computer science are systematized into a concept of an ad hoc system that is suitable as a mechanism for software development. The kernel of this methodology consists of a systematic approach for ad hoc systems development (specification, implementation, validation).
If your Macintosh provides the functionality and reliability that you need at the moment, there is no necessity to upgrade your system software. In theory, a user running a Quadra 700 computer could upgrade from System 7.0 all the way to Mac OS 8.1 but the Mac would probably need more memory, more hard disk space, a CD ROM drive and the owner would find that a few applications needed upgrading too. If it ain't broke, don't fix it...
