Chapter 21 Release Date
Chapter 21.. yes 21!

Updates to the series
I am also planning on releasing a preface chapter (Chapter 0) for a more in-depth introduction to the series as a whole, an overview of important concepts in C and assembly language, differences between applications and system programming and using them in system software. The basic idea is to give readers a better introduction to the series.
Also, within the next week or so readers might see an added gadget on all of the chapters pages allowing them to be translated to different languages. All spelling errors will also be corrected.
Please feel free to let me know if there are any comments, questions, or suggestions.
