A quick overview of Object-oriented program design, with special regard for operating-system development, this book will be of the greatest interest to those developers who are working with Taligent and its operating partners, as well as many other C++ programmers who are interested in a provocative summary of good OOP techniques.
An interesting and prescient C++ design guide, and a fine bit of industrial esoterica from the later era of Ed Yourden. There's nothing in here about design that isn't handled better in Martin Fowler or Design Patterns, and nothing about C++ design that isn't handled better in Large-Scale Software Design in C++, Scott Meyers or, for the C aspects, C Interfaces and Implementations. Futhermore, advanced C++ design was pretty much changed forever, IMHO, by the advent of folks like Alexandrescu and Vandevoorde and their popularization of extensive template metaprogramming. Nonetheless, it's a very short read (less than an hour), and what's an hour if there's even a single gem to be found?
