BrokenThorn OS Development Series

Link To Content
This series is intended to demonstrate and teach operating system development from the ground up. 
What is this about? 

Operating systems can be a very complex topic. Learning how operating systems work can be a great learning experience. 

The purpose of this series is to teach the black art of Operating System (OS) Development, from the ground up. Whether you want to make your own OS, or simply to learn how they work, this series is for you. 
What is an Operating System? 

An Operating System provides the basic functionality, look, and feel, for a computer. The primary purpose is to create a workable Operating Envirement for the user. 

An example of an Operating System is Windows, Linux, and Macintosh. 
If you have never programmed before 

Computer programming is designing and writing software, or programs, for the computer to load and execute. However, the Operating System needs to be designed with this functionality. 

An Operating System is not a single program, but a collection of software that work and communicate with each other. This is what I mean by "Operating Envirement". 

Because Operating Systems are a collection of software, in order to develop an Operating System, one must know how to develop software. That is, one must know computer programming. 

If you have never programmed before, take a look at the Requirements section below, and look no further. This section will have links to good tutorials and articals that could help you to learn computer programming with C++ and 80x86 Assembly Language.  

Introduction to Operating Systems

Link To Content
CS 537 is intended as a general introduction to the techniques used to implement operating systems and related kinds of systems software. Among the topics covered will be process management (creation, synchronization, and communication); processor scheduling; deadlock prevention, avoidance, and recovery; main-memory management; virtual memory management (swapping, paging, segmentation and page-replacement algorithms); control of disks and other input/output devices; file-system structure and implementation; and protection and security.

Skelix OS Tutorial

Link To Content
I am a person who always wants to dig deep into internals, so when I started a course about complier principles at college, I wrote a compiler, well, actually it's more like an assembler. When I started to use FreeBSD, I wanted to know how it works in the rawest way, so I tried to read the kernel source. Then as you can imagine, I soon realized that it was an impossible mission to be accomplished. I was swamped with millions of lines of code. All I want is an insect killer, but H-Bomb is the only thing they could provide. 

So I thought why can't I do it by myself, implement a simple OS kernel to show how it works from bootstrap to shell, finally I got Skelix. Skelix is a "skeleton" of an operation system kernel, it works in 32-bit protected mode, it demonstrates some basic concepts of how an os kernel works: bootstrap, task switching, paging, virtual memory, file system etc. in an i386 computer. 

This tutorial is about how to implement Skelix step by step to show the basic idea of how a simple os kernel works. However, Skelix is still nothing but a toy kernel so far. I keep it as simple as I can to make it look clear.  

The Little Book of Semaphores

Link To Content
The Little Book of Semaphores is a free (in both senses of the word) textbook that introduces the principles of synchronization for concurrent programming. 

In most computer science curricula, synchronization is a module in an Operating Systems class. OS textbooks present a standard set of problems with a standard set of solutions, but most students don't get a good understanding of the material or the ability to solve similar problems. 

The approach of this book is to identify patterns that are useful for a variety of synchronization problems and then show how they can be assembled into solutions. After each problem, the book offers a hint before showing a solution, giving students a better chance of discovering solutions on their own. 

The book covers the classical problems, including "Readers-writers," "Producer-consumer", and "Dining Philosophers." In addition, it collects a number of not-so-classical problems, some written by the author and some by other teachers and textbook writers. Readers are invited to create and submit new problems.  

The Operating System Resource Center

The Operating System Resource Center contains an enormous wealth of information for OS developers, useful for both beginners and advanced developers alike. 

Beginner programmers may find this resource to be a good companion to the articles/tutorials onhttp://www.osdev.org/wiki/Main_Page .
