Programs made for the Operating Systems course I took with Dr. René Mac Kinney Romero at Universidad Iberoamericana. This repo contains some low-level C programs that help you manage different things in an operating system; while taking this course my operating system was MacOS Ventura Version 13.0.1, but most things should work on Linux machines as well.
Some projects have Docker containers to provide a stable running environment.
Inside this repository you'll find a couple of interesting projects which I think are awesome!
These are three simple programs that recreates basic system utilities for MacOS.
These are two programs let's you compare the speed between running a sorting algorithm with threads and running this same algorithm with forks.
This program allows you to simulate a messenger through the use of a shared memory objects. In Linux machines this objects are found in the /dev/shmem directory, but in MacOS no such file exists.
To understand how shared memory is managed in MacOS read through the manual entry for
shm_open, there they state: "There is no visible entry in the file system for the created object in this implementation."
This program is an hexadecimal editor, you can use it to open any file.
This is a program that reads an HFS+ disk image and gives you information about its structure.
Instructions for running each program can be found in the README.md file of each project.
