Machine, Man and behavior

Machine and Man ? some one would rather say, there is no comparison,  man has a variety of behavior, every one on earth behaves differently in a certain situation.

But I think its just our perception, we all do behave same to one thing in a certain circumstances, exactly what we want from machines, e.g. when we touch to a hot iron(unconsciously),  we all do one thing to get our hand away from that iron with as much speed as possible…

Looking in a broder term, a person who is considered to be criminal, was not same since his birth, environment had be created for him to behave like this even before he came to this earth.

when we write a programming function for machine to define its behavior, we use same thing to behave differently based on what environment has been prepared for. similarly, man has only one nature and is born with that,

Of person X behaves in a way in a certain environment(considering all environment variables changing his behavior are known), then person Y must always do the same thing in similar environment.

Inventory is Evil

In business, either it is cutting edge technology, a shoe manufacturing company or what ever, business man has to pay the cost for keeping inventory.

As Tim Cook, the Corporate Operating Officer of Apple said, “Inventory, is fundamentally evil,”. “You kind of want to manage it like you’re in the dairy business,” he has said. “If it gets past its freshness date, you have a problem.”

Rule is simple, one should know customer’s expectation or (if possible) drive customer’s expectation. Let us have example of Cook’s apple,

The company torpedoed an entire quarter’s performance by announcing a new version of its PDA, which helped dry up sales of the old version, then failing to deliver the new product when the company said it would. We have exaples for appearance of  the iPhone, the iPod, any number of iMacs and MacBooks in stores under Cook’s team.

Private Browsing Mode

Firefox 3.1 will be having private browsing mode as per yahoo News.

This functionality is required in some case like when we are going to use a public computer for some reason.
In presence of Google’s Chrome, Apple’s Safari, and Microsoft’s Internet Explorer 8, this open source browser should have some thing to maintain its good market share
what should be the next thing a user may need with a browser ????

The Child Genius

Karl Friedrich Gauss displayed immense mathematical talent from a very early age. Stories tell of him being able to maintain his father’s business accounts at age three. In elementary school, he confounded his teacher by observing a pattern that enabled him to avoid a decidedly tedious calculation.

Gauss’s teacher had asked the class to add together all the numbers from 1 to 100.

You write down the sum twice, once in ascending order, then in descending order, like this:
1 + 2 + 3 + . . . + 98 + 99 + 100
100 + 99 + 98 + . . . + 3 + 2 + 1
Now you add the two sums, column by column, to give
101 + 101 + 101 + . . . + 101 + 101 + 101
There are exactly 100 copies of the number 101 in this sum, so its value is 100 × 101 = 10,100. Since this
product represents twice the answer.

So generic pattern found is as

1 + 2 + 3 + . . . + n = n(n + 1)/2

Methematical behaviors

Reference from “The Language of mathematics“

Prime Numbers primes seem to be in great abundance among the first hundred or so natural numbers, they start to thin out as you proceed up through the numbers, and it is not at all clear from
the observational evidence whether or not they eventually peter out altogether. For instance, there are eight
primes between 2 and 20, but only four between 102 and 120. Going further, of the hundred numbers
between 2,101 and 2,200, only ten are prime, and of the hundred between 10,000,001 and 10,000,100, only
two are prime. Do they really end up at some point…???

It can be checked by Euclid’s equation for next prime number,

P = p1 × p2 × . . . × pn + 1;

Artificial Neural Networks

Here is a very useful archive for newbies to Neural Networks and also for those who want to have a bird eye view about neural networks and related applications.

and this book is particularly for Unsupervised Learning in neural Networks.
