Windows95 Compared to Jesus

If you have half a brain, you can't help but notice the throng of publications, analysts and net users declaring Windows95 the Saviour of the Computer Industry. If you have less than half a brain, you probably believe it. Could it be?

To find out, let's compare Windows95 against a widely-accepted Saviour, Jesus of Nazareth:

Jesus Windows95

Jesus: Said, "Surely I come quickly."
Windows 95: Has been promised "any day now."

Jesus:Is taking a lot longer to actually arrive
Windows 95: Is taking a lot longer to actually
arrive.

Jesus: Can walk on water.
Windows 95: Can crawl on a 486.

Jesus: Sits in judgement at the pearly
gates.
Windows 95: Will be used to judge Bill Gates.

Jesus: Bible says, "In Him, all things Windows 95 doesn't even run all
are possible."
Windows 95: doesn't even run all
possible Windows apps.

Jesus: Started life as a carpenter.
Windows 95:Turns perfectly good computers into
furniture.

Jesus: Born in a manger.
Windows 95:Resembles something found in a barn.

Jesus:Remembered for protecting the
weak.
Windows 95:Has weak memory protection.

Jesus:Was raised from the dead.
Windows 95:Was created from Windows 3.1.

Jesus performed great works for
the multitudes.
Windows 95 multitasking performance
barely works.

Jesus has no sin.
Windows 95 has no shame.

if this offends any Christians out there, I don't really care. But you can email me if you think it will make you feel better.

As Good As It Gets

"Computers in the future may weigh no more than 1.5 tons." - Popular Mechanics, forecasting the relentless march of science, 1949.

"I think there is a world market for maybe five computers." - Thomas Watson, chairman of IBM, 1943

"I have traveled the length and breadth of this country and talked with the best people, and I can assure you that data processing is a fad that won't last out the year." - The editor in charge of business books for Prentice Hall, 1957

"But what ... is it good for?" - Engineer at the Advanced Computing Systems Division of IBM, 1968, commenting on the microchip.

"There is no reason anyone would want a computer in their home." - Ken Olson, president, chairman and founder of Digital Equipment Corp., 1977

"So we went to Atari and said, 'Hey, we've got this amazing thing, even built with some of your parts, and what do you think about funding us? Or we'll give it to you. We just want to do it. Pay our salary, we'll come work for you.' And they said, 'No.' So then we went to Hewlett Packard, and they said, 'Hey, we don't need you. You haven't got through college yet.'" - Apple Computer Inc. founder Steve Jobs on attempts to get Atari and HP interested in his and Steve Wozniak's personal computer.

Digits of Zero

Is zero a 1-digit number or a 0-digit number, or neither?

You may think that 0 is a 1-digit number. However, this will make 00 a 2-digit number, 000 a 3-digit number, and so on. Leading zeros do not count towards the digits, and 0 itself is a leading zero.

If you think that 0 is a 0-digit number, you're still wrong. 100 is a 3-digit number, 10 is a 2-digit number, 1 is a 1-digit number, and therefore, .1 is a 0-digit number, .01 is a -1-digit number, and so on. Therefore, the number of digits of a real number x is 1+int(lgx). Since lg0 is meaningless, the number of digits of 0 can't be defined.

The History of Operating Systems

The Dosfish

Long ago, in the days when all disks flopped in the breeze and the writing of words was on a star, the Blue Giant dug for the people the Pea Sea. But he needed a creature who could sail the waters, and would need for support but few rams.

So the Gateskeeper, who was said to be both micro and soft, caused to be fashioned a Dosfish, who was small and spry, and could swim the narrow sixteen-bit channel. But the Dosfish was not bright, and could be taught but few tricks. His alphabet had no A's, B's, or Q's, but a mere 640 K's, and the size of his file cabinet was limited by his own fat.

At first the people loved the Dosfish, for he was the only one who could swim the Pea Sea. But the people soon grew tired of commanding his line, and complained that he could neither be dragged or dropped. "Forsooth," they cried, "the Dosfish can do only one job at a time, and of names he knows only eight and three." And many of them left the Pea Sea for good, and went off in search of the Magic Apple.

Although many went, far more stayed, because admittance to the Pea Sea was cheap. So the Gateskeeper studied the Magic Apple, and rested awile in the Parc of the Xer Ox. And he made a Window that could ride on the Dosfish, and do its thinking for it. But the Window was slow, and it would break when the Dosfish got confused. So most people contented themselves with the Dosfish.

Now it came to pass that the Blue Giant came upon the Gateskeeper, and spoke thus: "Come, let us make of ourselves something greater than the Dosfish." The Blue Giant seemed like a humbug, so they called the new creature Oz II.

Now Oz II was smarter than the Dosfish, as most things are. It could drag and drop, and could keep files without becoming fat. But the people cared for it not. So the Blue Giant and the Gateskeeper promised another Oz II, to be called Oz II Too, that could swim fast in the new, 32-bit wide Pea Sea.

Then lo, a strange miracle occurred. Although the Window that rode on the Dosfish was slow, it was pretty, and the third window was the prettiest of all. And the people began to like the third window, and to use it. So the Gateskeeper turned to the Blue Giant and said "Fie on thee, for I need thee not. Keep thy Oz II Too, and I shall make of my Window an Entity that will not need the Dosfish, and will swim in the 32-bit Pea Sea."

Years passed, and the workshops of the Gateskeeper and the Blue Giant were many times overrun by insects. And the people went on using their Dosfish with a Window; even though the Dosfish would from time to time become confused and die, it could always be revived with three fingers. Then there came a day when the Blue Giant let forth his Oz II Too onto the world. The Oz II Too was indeed mighty, and awesome, and required a great ram, and the world was changed not a whit. For the people said "It is indeed great, but we see little application for it." And they were doubtful, because the Blue Giant had met with the Magic Apple, and together they were fashioning a Taligent, and the Taligent was made of objects, and was most pink.

Now the Gateskeeper had grown ambitious, and as he had been ambitious before he grew, he was now more ambitious still. So he protected his Window Entity with great security, and made its net work both in serving and with peers. And the Entity would swim, not in the Pea Sea, but also in the Oceans of Great Risk. "Yea," the Gateskeeper declared, "though my Entity will require a greater ram than Oz II Too, it will be more powerful than a world of Eunuchs.

And so the gateskeeper prepared to unleash his Entity to the world, in all but two cities. For he promised that a greater Window, a greater Entity, and even a greater Dosfish would appear one day in Chicago and Cairo, and it too would be built of objects.

Now the Eunuchs who lived in the Oceans of Great Risk, and who scorned the Pea Sea, began to look upon their world with fear. For the Pea Sea had grown and great ships were sailing in it, the Entity was about to invade their Ocenas, and it was rumored that files would be named in letters greater than eight. And the Eunuchs looked upon the Pea Sea, and many of them thought to immigrate.

Within the Oceans of Great Risk were many Sun Worshippers, and they had wanted to excel, and make their words perfect, and do their jobs as easy as one-two-three. And what's more, many of them no longer wanted to pay for the Risk. So the Sun Lord went to the Pea Sea, and got himself eighty-sixed.

And taking the next step was he of the NextStep, who had given up building his boxes of black. And he proclaimed loudly that he could help anyone make wondrous soft wares, then admitted meekly that only those who know him could use those wares, and he was made of objects, and required the biggest ram of all.

And the people looked out upon the Pea Sea, and they were sore amazed. And sore confused. And sore sore. And that is why, to this day, Ozes, Entities, and Eunuchs battle on the shores of the Pea Sea, but the people still travel on the simple Dosfish.

Mad Scientist

There was a mad scientist (a mad ...social... scientist) who kidnapped three colleagues, an engineer, a physicist, and a mathematician, and locked each of them in separate cells with plenty of canned food and water - but no can opener.

A month later, returning, the mad scientist went to the engineer's cell and found it long empty. The engineer had constructed a can opener from pocket trash, used aluminum shavings and dried sugar to make an explosive, and escaped.

The physicist had worked out the angle necessary to knock the lids off the tin cans by throwing them against the wall. She was developing a good pitching arm and a new quantum theory.

The mathematician had stacked the unopened cans into a surprising solution to the kissing problem; his dessicated corpse was propped calmly against a wall, and this was inscribed on the floor in blood:

Theorem: If I can't open these cans, I'll die.

Proof: assume the opposite...

Laws of Computing

When computing, whatever happens, behave as though you meant it to happen.

When you get to the point where you really understand your computer, it's probably obsolete.

The first place to look for information is in the section of the manual where you least expect to find it.

When the going gets tough, upgrade.

For every action, there is an equal and opposite malfunction.

He who laughs last probably made a back-up.

A complex system that does not work is invariably found to have evolved from a simpler system that worked just fine.

The number one cause of computer problems is computer solutions.

A computer program will always do what you tell it to do, but rarely what you want to do.
