Prostitution is legal in INDIA. Yes it is.

Prostitution is Legal in India.

Most people in India don't know that (contrary to popular belief) prostitution is legal in India.
Yes, you read that right.

In fact India happens to be one of the few countries where it is legal.
Now, here is the 'but' that you were waiting for.
There is a clause to this law. Prostitution is legal but pimping is not. So, exchange of sexual services for money is not a crime in India, But pimping or owning/running a brothel are crimes. Serious crimes in fact.
This is why India has prostitution but is not regulated.






Here, the countries marked in blue are the countries where prostitution is legal but pimping is not.
The countries in green are the one where prostitution is legal and is regulated.
The ones in red are those where prostitution is illegal.

How do computers work the way they do? When does electricity become executable logic and how?

 Let us start right from the bottom:

• Matter is composed of atoms (we can go smaller than this but this should be enough for this question)
• Atoms have electrons and flow of these electrons is defined as electricity
• Now, to make use of these electrons, we create transistors which can store/free electricity as needed. They are stored in units of 1 (5Volts) and 0 (0 Volts)
• An 8-bit number is then represented with 8 transistors. So 8-bit representation of the number 3 will be : 0000 0011. How is that achieved in hardware? Keep 8 transistors side-by-side (called registers and memory units). Make the first 6 transistors hold 0V and the next 2 transistors hold 5V
• Now, an organization of such registers and memory makes a cpu+ram
• To make it easy to compute using the CPU, we developed machine code. This language is what essentially runs on the CPU. What do I mean by "run"? It means, keep flipping bits. If I want to perform 2+3, in machine, I would store 2 in one register (register explained above) and 3 in another register. Then I would take these values to an Adder unit which would do a mathematical add (not the same as voltage addition) and give me the reply in another register. This is what a sample machine code would look like:

80 02 F3
80 03 F4
88 F3 F4 F5

Obviously, no one understood anything with this. So we came up with an ingenuous system to make it human readable. This is called assembly language. The following piece of code represents the above mentioned numbers:

MOVI 2, REG A
MOVI 3, REG B
ADD REG A, REG B, REG C (add A and B and store in C)

where MOVI = 80
REG A = F3
REG B = F4
REG C = F5
ADD = 88


Voila, our first coding language :)

• Now, assembly is too hard for humans to remember and code properly in. So they developed compilers that would convert a high level language like C to assembly language (remember, this assembly language does the actual flipping of bits)

So, a C representation of the above mentioned assembly would be:
{
int a = 2; b = 3;
c = a+b;
}

• Just like people could write poems with English and not with hand signs, we realized that with an expressive language, people could write some better programs. Then compile it to assembly. Then that would flip bits in registers. Which in turn would affect transistors, which affect flow of electrons
• With the above found expressiveness, we wrote operating systems to maximize hardware usage, since it was seen that the CPU remained idle while we fetched data from disk
• Everything from your keyboard input to mouse to desktop to windows to sound is a program written in such expressive languages, running on top of the OS
• On the OS, we developed a network stack called TCP/IP. This stack provided a standardized methodology for computers to communicate with each other
• Once that was working and we managed to hook computers to each other using cables, we went on to create WWW and http. This allowed people from different networks to communicate with each other. Note that http is a protocol. Servers and Clients are programs that follow (at least) http in addition to internal protocols.

Let's walk the other way, from software to electrons now

• When you type Google in the browser and hit Enter key, an http request is sent from your browser (the client) to Google (server)
• In your own computer, the browser is a program written in C/C++
• This gets compiled to assembly (actually browser is already compiled, you're just giving input numbers to the compiled browser)
• The operating system (windows/linux etc) and device drivers are all already compiled to assembly and are running on your machine
• When the browser assembly gets it's turn to run on the CPU, it runs the assembly
• This assembly code does flipping of bits in registers and memory
• The registers and memory are composed of transistors
• Transistors control the flow of electrons and hence electricity.

Computers are man-made miracles of the highest order. No single person could have thought of all this. It has taken more than 50 years and millions of smart people to get to this point. Most computer programmers and professionals I've talked to, have an incomplete picture of what a computer actually is and (as you put it) how does electricity get converted to software.

What was the IQ of Shakuntala Devi, The Human Calculator?

While Shakuntala Devi could multiply two 13 digit numbers just under 28 seconds and tell the eighth root of a 14-digit number in less than 10 seconds, everytime, correctly, she could not recite the numbers given to her in the IQ test in reverse order and could only utter 4 digits before stumbling! [1] She was labelled as "average".

And she once calculated 23rd root of a 201-digit number in 50 seconds which was later verified by writing a special program on Univac 1101 at the US Bureau of Standards. [2]

At the University of Rome one of her answers to the problems was found to be wrong by the calculating machine, but after re-checking it was found that the machine had made the mistake and not Shakuntala.

Oh and meanwhile I just came to know I have an IQ of 130! [3] I beat "The Human Calculator" :D
IQ is for fun and doesn't correspond to intellect as much as you'd think :)

This is why he is named as God Of Cricket. Happy?

Some records will be broken :'(

Why is mathematical constant pi so unique ?

• William Jones is the person, who introduced the symbol of Pi in the year 1706. But it was Leonhard Euler who popularized it in 1737.
• Pi has about 6.4 billion known digits which would take a person roughly 133 years to recite without stopping.
•  The world record holder for the most memorized digits of Pi took nine hours to recite over 44,000 digits of Pi.
• Some scientists use the fractions 22/7, 355/113  and 104348/33215 to approximate Pi. These fractions have an error of only 0.04025%, 0.00000849% and 0.00000001056% respectively. 
•  The Babylonians, who found the first known value of Pi, used the fraction 25/8. Although Pi can be approximated by a fraction, it cannot be expressed as a fraction because it is an irrational number. In other words, Pi’s digits go on randomly for infinite.
• It is impossible to 'square the circle'. In other words, you can't draw a square with the same area as a circle using standard straight-edge and compass construction in a finite number of steps. The Greeks were obsessed with trying to do this. A long time ago people thought there was an illness attached to trying to 'square a cirle' called Morbus Cyclometricus.
• If one were to find the circumference of a circle the size of the known universe, requiring that the circumference be accurate to within the radius of one proton, only 39 decimal places of Pi would be necessary.
• At position 763 there are six nines in a row. This is known as the Feynman Point.
• Pi day is celebrated on March 14 at the Exploratorium in San Francisco (March 14 is 3/14) at 1:59 PST which is 3.14159. Pi Approximation Day is on the 22/7 - that is, July 22. For the past few years, people at Chalmers University have celebrated it.
• There are people who believe that Pi contains the answer to the universe, or that information is held in the digits. It has even been suggested it contains the VOICE OF GOD. In Carl Sagan's book 'Contact' the places of Pi are found to contain a message from the beings that built the universe.
• With the help of Hitachi SR 8000, a powerful computer, a Japanese scientist found 1.24 trillion digits of Pi, breaking all the previous records.
• There are no zeros in the first 31 digits of Pi.
• First six digits of Pi appear in order at least six times among the first ten million decimals of Pi.

How to create file server using python

We can use a simple python command to create our own server.

Install python : Welcome to Python.org

Open your console. (Terminal in Linux/Mac OSX and cmd in Windows).
Type the following:
python -m SimpleHTTPServer.

For python 3.0 and above : 

python -m http.server 7000


That's it! You have created your own file server. You can now access the files on this machine from other machines over the internet!





You can access the files on this server through your web browser. Just type the following:


http:// [ip-address-of-server]:8000








This will list all the files in the server, and you can browse and download any permitted files just like you do on a normal website.

To find the IP address, I have another section here.

2. How to find your own IP address:

i ) For Windows:

Type:
(windows key + r)
and press [enter].
Type
ipconfig




3. The IPv4 Address section is your required IP.

ii) For Linux/Mac OS X:

Open the terminal, type:

ifconfig
