Search for text in files opened in the current folder in the current work space in Perforce. I would suggest using the part before the string passed to grep as an alias in your bashrc so you can use something like grep_p4o "text to search" directly.
alias grep_p4o='p4 opened | (folder="${PWD##*/}"; sed -e "s/.*${folder}\/\(.*\)#.*/\1/g") | xargs -o grep --color=auto -H'

Created February 11, 2015 01:00
Monte Carlo Method for approximating the value of pi using ratio of area of circle inscribed in unit length square.
"""
Using Monte Carlo to find the value of pi.
Intiution: Ratio of area of circle to area of uniq length squre it is inscribed it can be used to approximate pi.
Area of circle = pi/4
Area of square = 1
Ratio = pi/4
Let us generate random points x,y inside the square. The probabilty of the point being inside circle is equal to the above ratio.
Circle centered on origin.
Given: -0.5 <= x,y <= 0.5
A point is inside circle if x**2 + y**2 <= 1/4
