The Game of Life

Here we've designed and implemented Conway's Game of Life, game algorithm; invented by John Conway in 1970. The rules of this 0-player game (a video game playing without user input) are:

1. Any live cell with fewer than two live neighbors dies, as if by under-population.
2. Any live cell with two or three live neighbors lives on to the next generation.
3. Any live cell with more than three live neighbors dies, as if by overpopulation.
4. Any dead cell with exactly three live neighbors becomes a live cell, as if by reproduction.

The motivation for this project was to become familiar with parallel computing primarily on the CPU, but also on the GPU which utilizes the stream processing paradigm.

Usage

There are 6 different implementations:

1. Serial
2. Serial with OpenMP
3. MPI
4. MPI with OpenMP (aka Hybrid)
5. NVidia CUDA...

Process Hacking (COD4) Tutorial

Generic Windows process hacking application. This time the victim being Call of Duty 4 (the original - 2007).

What do we mean by hacking? Hacking is gaining access to a system in a manner that was not intended by its developer.

Here we do something really very simple and easy. We will change some on screen visual values in our program.

A. We find the process' HANDLE. There are 2 ways to do this.

I. By getting the window Handle (HWND)

1. HWND windowHandle = FindWindowW( nullptr, processName ) to get the window handle
2. GetWindowThreadProcessId( windowHandle, &pid ) to get the pid
3. and finally OpenProcess( PROCESS_ALL_ACCESS, false, *pid ); to get the process Handle

This is the method I use in this example.

II. By taking a...

Hooking Tutorial

Here you will learn about this ancient miracle cure called Hooking. Our ancestors used hooking to catch fish! No just kidding, lets get to it.. But before we dive in, I'll provide a little introduction to the Portable Executable (PE). Don't skip it; its understanding is crucial to get to the meat and potatoes of this tutorial.

The Portable Executable (PE) format is a file format for executables, object code, DLLs, FON Font files, and others used in 32-bit and 64-bit versions of Windows operating systems. It is a data structure format that encapsulates information regarding dynamic library references for linking, API export and import tables, resource management data and thread-local storage (TLS) data.

The Extensible Firmware Interface (EFI) specification states that PE is the standard executable format in EFI environments. On NT family of operating systems, the PE format is used for EXE, DLL, SYS (device...

Install Python Packages script

Merely a handy run-and-forget script that installs all python packages specified in a text file “packages.txt”. I've used it countless times. Press a button and let the console ASCII text flow.

You will more than likely need to run the script (or Visual Studio if you're using that to run it) with administrator privileges, or you'll be denied permission.

Requirements:

• Python 3.x version installed (only tested with 3.5 and 3.6.6)
• Latest pip version for the specified python version installed

I've used Windows Visual Studio IDE with Python tools and Python 3.6.6 interpreter.

Math Handbook

A handbook for logic, set theory, algebra, geometry, video game math concepts, graph theory, Calculus, discrete math, probability, statistics, number theory, numerical analysis, vector algebra, physics, chemistry and more goodies I've worked on and off throughout my educational years.

I compiled this several years ago and it's been left dormant among the circuits of my computer..

I provide the source files, which you can open yourself with TexMaker.

The built pdf file is called “Math Handbook.pdf”.

As a disclaimer, this compilation could be of use to some, to others it could be another pile jumbled up notes.

I release it in the hope that it might prove useful to at least one person.

I used Windows LATEX with TexMaker.

Maze Solving

A maze is a programming puzzle involving a collection of paths. What we seek to do here is construct an algorithm that will traverse a path starting from a specified location and ending to a destination location.

A Maze is typically given as an N*N array, eg. maze[N][N]. Imagine you're a rat trapped in the maze and you have to traverse the blocks to go from the Start to the Destination block. Reaching the destination blocks allows you to escape the maze and go free! The rat only possesses elementary movement abilities, either left/right or up/down. It's a 2d world for the rat and it suits us nicely.

In this example, we want to be able to construct a maze dynamically based on however many amount of rows and columns it consists of; for this reason we opted to use a vector of vectors - 2d vector called "maze".

You can provide whatever maze you want as input to this program. Use a file, place it somewhere inside the project and run the program by...

RC Car

Forenote: RC may stand for either Remote Control, or Radio Control.

This is the implementation of a Radio Controlled (RC) car scaled 1-16. When talking about “implementation” I refer to the electromechanical assembly of the parts required, their wiring and microcontroller programming.

The goal is to move the car around telepathically (no just kidding) using a transmitter i.e. remotely controlling it via radio frequency signal waves and technology used to decode and encode those signals on the receive and transmitter ends respectively.

Hardware & Software used:

• the popular programmable MSP430 microcontroller chip (MCU) from Texas Instruments
• HC-06 Bluetooth module
• L293D(ne) H-bridge chip
• IAR Embedded Workbench 7 for Windows, student license for programming
• Windows 8.1 x86_64
• Tera Term and Putty for IO serial comms via UART interface.

You will have...

Tile Game (Pokemon Wannabe)

A minimal but functional tile-based 2d game the likes of the good ol' Pokemon Gen 2. This was my first real big accomplishment in my video game learning journey. I was inspired by Pokemon Crystal, which was the game that really introduced me into video games.
