If you ever want to have a lot of fun, I recommend that you go off and program an imbedded system. The salient characteristic of an imbedded system is that it cannot be allowed to get into a state from which only direct intervention will suffice to remove it. An imbedded system can't permanently trust anything it hears from the outside world. It must sniff around, adapt, consider, sniff around, and adapt again. I'm not talking about ordinary modular programming carefulness here. No. Programming an imbedded system calls for undiluted raging maniacal paranoia. For example, our ethernet front ends need to know what network number they are on so that they can address and route PUPs properly. How do you find out what your network number is? Easy, you ask a gateway. Gateways are required by definition to know their correct network numbers. Once you've got your network number, you start using it and before you can blink you've got it wired into fifteen different sockets spread all over creation. Now what happens when the panic-stricken operator realizes he was running the wrong version of the gateway which was giving out the wrong network number? Never supposed to happen. Tough. Supposing that your software discovers that the gateway is now giving out a different network number than before, what's it supposed to do about it? This is not discussed in the protocol document. Never supposed to happen. Tough. I think you get my drift. | |
It appears that after his death, Albert Einstein found himself working as the doorkeeper at the Pearly Gates. One slow day, he found that he had time to chat with the new entrants. To the first one he asked, "What's your IQ?" The new arrival replied, "190". They discussed Einstein's theory of relativity for hours. When the second new arrival came, Einstein once again inquired as to the newcomer's IQ. The answer this time came "120". To which Einstein replied, "Tell me, how did the Cubs do this year?" and they proceeded to talk for half an hour or so. To the final arrival, Einstein once again posed the question, "What's your IQ?". Upon receiving the answer "70", Einstein smiled and replied, "Got a minute to tell me about VMS 4.0?" | |
"A commercial, and in some respects a social, doubt has been started within the last year or two, whether or not it is right to discuss so openly the security or insecurity of locks. Many well-meaning persons suppose that the discus- sion respecting the means for baffling the supposed safety of locks offers a premium for dishonesty, by showing others how to be dishonest. This is a fal- lacy. Rogues are very keen in their profession, and already know much more than we can teach them respecting their several kinds of roguery. Rogues knew a good deal about lockpicking long before locksmiths discussed it among them- selves, as they have lately done. If a lock -- let it have been made in what- ever country, or by whatever maker -- is not so inviolable as it has hitherto been deemed to be, surely it is in the interest of *honest* persons to know this fact, because the *dishonest* are tolerably certain to be the first to apply the knowledge practically; and the spread of knowledge is necessary to give fair play to those who might suffer by ignorance. It cannot be too ear- nestly urged, that an acquaintance with real facts will, in the end, be better for all parties." -- Charles Tomlinson's Rudimentary Treatise on the Construction of Locks, published around 1850 | |

The eye is a menace to clear sight, the ear is a menace to subtle hearing, the mind is a menace to wisdom, every organ of the senses is a menace to its own capacity. ... Fuss, the god of the Southern Ocean, and Fret, the god of the Northern Ocean, happened once to meet in the realm of Chaos, the god of the center. Chaos treated them very handsomely and they discussed together what they could do to repay his kindness. They had noticed that, whereas everyone else had seven apertures, for sight, hearing, eating, breathing and so on, Chaos had none. So they decided to make the experiment of boring holes in him. Every day they bored a hole, and on the seventh day, Chaos died. -- Chuang Tzu |
