This is the first kernel I have managed to turn into a minimally useful program.
And it is 100% Public Domain.
I consider it as the Level 1 of an operating system, and the simplest yet useable you will easily find around.
What is different about it from a regular tutorial is that it consolidates several features that would not be connected together or useable in such a single-topic-centered tutorial.
Although I still need to write documentation for every single algorithm and trick used, but I have such documentation partially written already, and I just need to make a list of tutorials to explain how this kernel works.
As ýou can see, it makes for sort of a pre-alpha DOS-like operating system with modern capabilities and resources at its reach. It is ideal for a first learning aid for dynamic loading of programs (with static memory), a basic methodology of making use of kernel library functions, interpreting a command line.
And more importantly, it is a DOS-like system that is tiny, minimally useable, easy to understand, without features that aren't strictly required for it to work, and because of it, can allow a developer to also create simple test applications, and eventually escalate this kernel/system with more complete features, leaving footsteps of development with extremely well-defined complexity levels, up to a full-featured system, that is much more explained than virtually any other (non-educationally yet real-world, oriented) operating system in existence.
Obviously there is a lot to do yet, so much more. But this should be a good start, and in many senses, more beneficial than just using other low-level test system such as MS-DOS or FreeDOS, because it is easier to understand, and from here we can improve a lot if we are smart.
