I can teach you the physics of riding a bicycle. Indeed, the classical mathematics is relatively straightforward. Gravity, friction, angular momentum, center of mass, and so forth, can be demonstrated with less than a page full of equations. Given those formulae I could provide you that bicycle riding is practical and give you all the knowledge you needed to make it work. And you'd still fall down the first time you climbed on that bike. Coding is no different.
GitHub surely does its thing. But as from my side you have no cookies, no IP or other kind of trackers, no ads, no logs about whatever you do. Nothing. The entire codebase is 100% transparent for everyone. Technically there are no ways I can "trick" the system to secretly add a spyware or an ad spammer.
My approach is to constantly improve this project on a daily basis. Even if the next morning I will not have the energy for the corporate work. Still with all of this, I am asking for your patience. I would love to do more, but maybe at some point I will have this wonderful opportunity.
You can use any content and file from this github repository entirely or just a portion of it in any way it helps you. There is NO any legal restriction from my part. Referencing this github page as the source for any content you copied is appreciated but never mandatory.
The book provides a general and simplified look about how a computer works, which are the main components that makes it easily programmable, how a program really looks and gets executed on a computer. All the examples and illustrations are well explained so the entire book can be easily understood. It can give you the taste about the different aspects any programming language deals with in different ways.
