RECEME - Remote Command Execution through eMail Exchange
A service concept is implemented here for seamless & connectionless computation from anywhere to anywhere
REmote Command Execution through eMail Exchange or RECEME successfully attempts to solve the problem of remote code execution. The proposed solution executes any .Net runnable code on a computer(where the service application is up and running) in the form of a 'ICommand'.
The commands can be fired from any other location by sending an email/twit/(or any other mode in principle eg sms/phone/etc) to the connected communication client (email-box in the current implementation).

PROBLEM: Game of life
The universe of the Game of Life is an infinite two-dimensional orthogonal grid of square cells, each of which is in one of two possible states, live or dead. Every cell interacts with its eight neighbours, which are the cells that are directly horizontally, vertically, or diagonally adjacent. At each step in time, the following transitions occur:
1. Any live cell with fewer than two live neighbours dies, as if by loneliness.
2. Any live cell with more than three live neighbours dies, as if by overcrowding.
3. Any live cell with two or three live neighbours lives, unchanged, to the next generation.
4. Any dead cell with exactly three live neighbours comes to life.
5. Any dead cell with age > 3 dies (additional rule). Every generation creates an age for the cells
The initial pattern constitutes the 'seed' of the system. The first generation is created by applying the above rules simultaneously to every cell in the seed — births and deaths happen simultaneously, and the discrete moment at which this happens is sometimes called a tick. (In other words, each generation is a pure function of the one before.) The rules continue to be applied repeatedly to create further generations.
Problem.
The inputs below represent the cells in the universe as X or - . X is a alive cell. - is a dead cell or no cell . The below inputs provide the provide pattern or initial cells in the universe . The output is the state of the system in the next tick (one run of the application of all the rules) , represented in the same format.

ScreenShot
with mouse cursor (shape and position)
Windows default screenshot generator (using print-screen) does not capture the mouse position and shape. This is a nifty tool to capture the mouse shape and position using basic win32.
Keep pressing F7 and the images are dumped in C:\

PROBLEM : MARS ROVERS
A squad of robotic rovers are to be landed by NASA on a plateau on Mars.This plateau, which is curiously rectangular, must be navigated by therovers so that their on-board cameras can get a complete view of thesurrounding terrain to send back to Earth.
A rover's position and location is represented by a combination of x and yco-ordinates and a letter representing one of the four cardinal compasspoints. The plateau is divided up into a grid to simplify navigation. Anexample position might be 0, 0, N, which means the rover is in the bottomleft corner and facing North.
In order to control a rover, NASA sends a simple string of letters. Thepossible letters are 'L', 'R' and 'M'. 'L' and 'R' makes the rover spin 90degrees left or right respectively, without moving from its current spot.'M' means move forward one grid point, and maintain the same heading.
Assume that the square directly North from (x, y) is (x, y+1).
INPUT:
The first line of input is the upper-right coordinates of the plateau, thelower-left coordinates are assumed to be 0,0.
The rest of the input is information pertaining to the rovers that havebeen deployed. Each rover has two lines of input. The first line gives therover's position, and the second line is a series of instructions tellingthe rover how to explore the plateau.
The position is made up of two integers and a letter separated by spaces,corresponding to the x and y co-ordinates and the rover's orientation.
Each rover will be finished sequentially, which means that the second roverwon't start to move until the first one has finished moving.
OUTPUT
The output for each rover should be its final co-ordinates and heading.
INPUT AND OUTPUT
Test Input:
5 5
1 2 N
LMLMLMLMM
3 3 E
MMRMMRMRRM
Expected Output:
1 3 N
5 1 E
