Summary:

Operating systems are large and complex, and yet must function with near-absolute reliability–that’s why they’re a class unto themselves in the field of software development. Since its first release 20 years ago, “the dinosaur book”–Operating System Concepts by Abraham Silberschatz, Peter Baer Galvin, and Greg Gagne–has been a valuable reference for designers and implementers of operating systems. The newly released sixth edition of this book maintains the volume’s authority with new sections on thread management, distributed processes, and the Java Virtual Machine (JVM). There’s also information on the workings of the latest crop of operating systems, including Microsoft Windows 2000, Linux, FreeBSD, and compact operating systems for handheld devices.

This book is concerned with the design of operating systems, which is to say it enumerates the problems that pop up in the creation of efficient systems and explores alternative ways of dealing with them, detailing the advantages and shortcomings of each. For example, in their chapter on scheduling CPU activity, the authors explain several algorithms (first-come, first-served, and round-robin scheduling, among others) for allocating the capacity of single and multiple processors among jobs. They highlight the relative advantages of each, and explain how several real-life operating systems solve the problem. They then present the reader with exercises (this book is essentially a university textbook) that inspire thought and discussion. –David Wall

Topics covered:

The problems faced by designers of system software for electronic computers, and strategies that have been developed over the past 20 years to address (and, in some cases, solve) them. Problems of CPU scheduling, memory allocation, paging, processes and threads, storage management, distributed processes and storage mechanisms, and security are all discussed thoroughly and with many authoritative references.

Summary:
You’re not alone. At any given moment, somewhere in the world someone struggles with the same software design problems you have. You know you don’t want to reinvent the wheel (or worse, a flat tire), so you look to Design Patterns–the lessons learned by those who’ve faced the same problems. With Design Patterns, you get to take advantage of the best practices and experience of others, so that you can spend your time on…something else. Something more challenging. Something more complex. Something more fun. You want to learn about the patterns that matter–why to use them, when to use them, how to use them (and when NOT to use them). But you don’t just want to see how patterns look in a book, you want to know how they look “in the wild”. In their native environment. In other words, in real world applications. You also want to learn how patterns are used in the Java API, and how to exploit Java’s built-in pattern support in your own code. You want to learn the real OO design principles and why everything your boss told you about inheritance might be wrong (and what to do instead). You want to learn how those principles will help the next time you’re up a creek without a design paddle pattern. Most importantly, you want to learn the “secret language” of Design Patterns so that you can hold your own with your co-worker (and impress cocktail party guests) when he casually mentions his stunningly clever use of Command, Facade, Proxy, and Factory in between sips of a martini. You’ll easily counter with your deep understanding of why Singleton isn’t as simple as it sounds, how the Factory is so often misunderstood, or on the real relationship between Decorator, Facade and Adapter. With Head First Design Patterns, you’ll avoid the embarrassment of thinking Decorator is something from the “Trading Spaces” show. Best of all, in a way that won’t put you to sleep! We think your time is too important (and too short) to spend it struggling with academic texts. If you’ve read a Head First book, you know what to expect–a visually-rich format designed for the way your brain works. Using the latest research in neurobiology, cognitive science, and learning theory, Head First Design Patterns will load patterns into your brain in a way that sticks. In a way that lets you put them to work immediately. In a way that makes you better at solving software design problems, and better at speaking the language of patterns with others on your team.

Introduction
The guitar is a wonderfully versatile instrument. It is portable, needs no accompanist because it provides harmony as well as melody, and has an intrinsically beautiful tone which is sensitive to human touch. The higher levels of solo playing take time and practice, as with any instrument, but the guitar can be a pleasure from the first day and the first successful sounding of a chord.

I have deliberately departed from conventional teaching methods in this book to try to give you a quick start at enjoyable music without too much theory. I have done this by relying on the help of the tablature system an easy way to show where to place the fingers which avoids some of the trickier aspects of standard notation such as sharps and flats. This does not mean that these topics are bypassed. They’re all there, but thanks to tablature you don’t have to hold back from playing interesting pieces while you learn the fundamentals of music.
