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. ...

Debugging with GDB
The GNU Debugger allows you to see what is going on "inside" a program while it executes - or what a program was doing at the moment it crashed. GDB supports C, C++, Java, Fortran and Assembly among other languages; it is also designed to work closely with the GNU Compiler Collection (GCC). The GNU Debugger Program has four special features that helps you catch bugs in the act: It starts your program for you, specifying anything that might affect it's behavior. Makes your program stop under specified conditions. Examines what happened when the program stopped. Allows you to experiment with changes to see what effect they have on the program. This book will show you: setting and clearing breakpoints examining the stack, source files and data examining the symbol table altering program execution specifying a target for debugging how to control the debugger how to use canned command sequences how to install GDB and much more! This manual is written for programmers. It is designed so someo ...
