is it also right if i want to use same schema/table for every request data storing????
how can i distinguish themselves.... (i am processing json data)???
i am using this

Introduction
The Prime Counting Function, also known as the Pi function π(x), returns the amount of primes less than or equal to x.
Challenge
Your program will take an integer x which you can assume to be positive, and output a single integer equal to the amount of primes less than or equal t...
I recently wrote a simple BrainF*** interpreter in Ruby:
require "io/console"
$VALID = "+-<>.,"
def parse(code, level=0)
ast = []
while !code.empty? do
c = code.shift
if c == "]" then
if level == 0 then
throw Exception.new "Unmatched brackets...
@flawr: This Math.SE question just reminded me of how, yesterday while I was tutoring a student in Differential Equations, I decomposed a fraction into three parts (Wikipedia). I then had something like an epiphany where I realized that the denominators of the resulting fractions were basically basis vectors.
Unfortunately, the student didn't know Linear Algebra, but man, that was a cool realization.
The fraction was $\frac{x^2+1}{x-x^3}$, incidentally, which decomposes to $\frac{1}{x} + \frac{1}{1-x} - \frac{1}{1+x}$. Since these are linearly independent, it immediately follows that any polynomial with $x-x^3$ in the denominator and a numerator that is at most degree 2 can be decomposed into fractions with denominators $x$, $1-x$, and $1+x$.
I overloaded some C# operators to get a pseudo version of the Brainfuck symbols in the effort of understanding the flow of this language.
I got this version:
void Main()
{
/*
* Write `Hello World!`
* using operators overloading for brainfuck symbols
*/
var _ = ne...
What I don't like about Evernote (I never used it, so I may be wrong) is that it seems to be one of those apps who wants to do everything: notes, calendar, OCR, and probably more. But then, I'm probably wrong, as everyone seems to like. What was your experience with it? Why are you moving away?
@LuisMendo it does try to do everything but I didn't really mind that (I just ignored the features I didn't use). I'm moving away from it because they've changed their business model so that you can now only use it for free on two devices and I don't use it so actively that I feel like paying for it.
Just realized that we're coming up on Winterbash 2016 then realized that the first thing that comes to my mind when I think about the winter season is Winterbash and not Christmas
(Oh look, I stumbled upon framsticks.com, which is a cool artifical life software, is open source, shareware, but has a free command line interface. WANT.)
Tic-Tac-Latin!
This is a true story, so names have been altered.
My latin teacher, Mr. Latin, created his own proprietary (no joke) tic tac toe variant let's call it tic-tac-latin. The game is simple, it is essentially tic tac toe played on a four by four grid.

@ConorO'Brien Look. The set of prime factors of 1,000,000 are: {2^6*5^6} There is no other possible set of prime factors, by definition. Arranging numbers but not changing them doesn't count, because the arrangement isn't labelled as unique in this case.
