The Design and Implementation of the Anykernel and Rump Kernels
The mission of the first edition of this book was to introduce the anykernel and rump kernels and motivate their existence. Additionally, we explored the characteristics of the technology through various experiments. The paramount, often criminally overlooked experiment was the one hiding in plain sight: is it possible to construct the system in a sustainable, real-world compatible fashion. That paramount experiment was shown to be a success, and that result has not changed since the original publication, only strengthened. The core technology is still almost identical to the one described in the original book. This new edition has been written to account for the practical experiences from new use cases, many of which were proposed in the first edition, but which have since become reality. To start off, we will look at operating systems in general: what one is, how they developed throughout history, where they are now, what the problem is, and why the time is now ripe for change. ...

The Recursive Book of Recursion
Recursion has an intimidating reputation: it's considered to be an advanced computer science topic frequently brought up in coding interviews. But there's nothing magical about recursion. The Recursive Book of Recursion uses Python and JavaScript examples to teach the basics of recursion, exposing the ways that it's often poorly taught and clarifying the fundamental principles of all recursive algorithms. You'll learn when to use recursive functions (and, most importantly, when not to use them), how to implement the classic recursive algorithms often brought up in job interviews, and how recursive techniques can help solve countless problems involving tree traversal, combinatorics, and other tricky topics. Al Sweigart has built a career explaining programming concepts in a fun, approachable manner. If you've shied away from learning recursion but want to add this technique to your programming toolkit, or if you're racing to prepare for your next job interview, this book is for y ...
