Description
Book SynopsisLike the highly regarded first edition, this second edition of Understanding the Machine covers machine organisation and computer science topics like the CPU, machine architecture, memory and cache organisation, I/O and peripheral devices, and how the decoding and execution of machine instructions affects software performance. This edition has been updated to cover 64-bit machines, newer peripheral devices, larger memory systems, large-scale SSDs, and newer CPUs like those used in personal computers and tablets.
Trade Review"Sooner or later it makes sense to get a grip on what happens underneath the interpreter and compiler, even below the abstraction layer that the operating system provides. . . . This book leads you a part of the way to this knowledge. In a clear and understandable writing that makes it a joy to read."
—Thomas Manthey, Amazon Reviewer
Praise for the first edition of Write Great Code, Volume 1:"Today's programmers can hardly keep up with the race against inhumane deadlines and new technologies; therefore, they rarely have a chance to learn the basics of computer architectures and the inner-working of their programming languages. This book fills in the gaps. I strongly recommend it."

Write Great Code "isn't your typical 'teach yourself to program' book. . . It's relevant to all languages, and all levels of programming experience. . . Run, don't walk, to buy and read this book."

Bay Area Large Installation System Administrators (BayLISA)5/5 stars: "[
Write Great Code] fills in the blanks nicely and really could be part of a Computer Science degree required reading set... Once this book is read, you will have a greater understanding and appreciation for code that is written efficiently - and you may just know enough to do that yourself. At least you will have a great start at the art of crafting efficient software."
