Significant numbers of poorly designed programs have been created by less-experienced developers, resulting in applications that are inefficient and hard to maintain and extend. Increasingly, software system professionals are discovering just how difficult it is to work with these inherited, non-optimal applications. For several years, expert-level object programmers have employed a growing collection of techniques to improve the structural integrity and performance of such existing software programs. Referred to as refactoring, these practices have remained in the domain of experts because no attempt has been made to transcribe the lore into a form that all developers could use... until now. In Refactoring: Improving the Design of Existing Software, renowned object technology mentor Martin Fowler breaks new ground, demystifying these master practices and demonstrating how software practitioners can realize the significant benefits of this new process.

    Tracing the rise, fall, and alarming resurrection of the digital mafia behind the two largest spam pharmacies and countless viruses, phishing, and spyware attacks he delivers the first definitive narrative of the global spam problem and its threat to consumers everywhere.Blending cutting-edge research, investigative reporting, and firsthand interviews, this terrifying true story reveals how we unwittingly invite these digital thieves into our lives every day. From unassuming computer programmers right next door to digital mobsters like "Cosma" who unleashed a massive malware attack that has stolen thousands of Americans' logins and passwords, Krebs uncovers the shocking lengths to which these people will go to profit from our data and our wallets.Not only are hundreds of thousands of Americans exposing themselves to fraud and dangerously toxic products from rogue online pharmacies, but even those who never open junk messages are at risk. As Krebs notes, spammers can—and do—hack into accounts through these emails, harvest personal information like usernames and passwords, and sell them on the digital black market. The fallout from this global epidemic doesn't just cost consumers and companies billions, it costs lives too.Fast-paced and utterly gripping, Spam Nation ultimately proposes concrete solutions for protecting ourselves online and stemming this tidal wave of cybercrime, before it's too late."Krebs's talent for exposing the weaknesses in online security has earned him respect in the IT business and loathing among cybercriminals. His track record of scoops has helped him become the rare blogger who supports himself on the strength of his reputation for hard-nosed reporting." Bloomberg Businessweek

    The general said it was. This set in motion the first presidential directive on computer security.The first use of cyber techniques in battle occurred in George H.W. Bush's Kuwait invasion in 1991 to disable Saddam's military communications. One year later, the NSA Director watched Sneakers, in which one of the characters says wars will soon be decided not by bullets or bombs but by information. The NSA and the Pentagon have been rowing over control of cyber weapons ever since.From the 1994 (aborted) US invasion of Haiti, when the plan was to neutralize Haitian air-defenses by making all the telephones in Haiti busy at the same time, to Obama's Defense Department 2015 report on cyber policy that spells out the lead role played by our offensive operation, Fred Kaplan tells the story of the NSA and the Pentagon as they explore, exploit, fight, and defend the US. Dark Territory reveals all the details, including the 1998 incident when someone hacked into major US military commands and it wasn't Iraq, but two teenagers from California; how Israeli jets bomb a nuclear reactor in Syria in 2007 by hacking into Syrian air-defense radar system; the time in 2014 when North Korea hacks Sony's networks to pressure the studio to cancel a major Hollywood blockbuster; and many more. Dark Territory is the most urgent and controversial topic in national defense policy.

    With a blend of software engineering facts and thought-provoking opinions, Fred Brooks offers insight for anyone managing complex projects. These essays draw from his experience as project manager for the IBM System/360 computer family and then for OS/360, its massive software system. Now, 45 years after the initial publication of his book, Brooks has revisited his original ideas and added new thoughts and advice, both for readers already familiar with his work and for readers discovering it for the first time.The added chapters contain (1) a crisp condensation of all the propositions asserted in the original book, including Brooks' central argument in The Mythical Man-Month: that large programming projects suffer management problems different from small ones due to the division of labor; that the conceptual integrity of the product is therefore critical; and that it is difficult but possible to achieve this unity; (2) Brooks' view of these propositions a generation later; (3) a reprint of his classic 1986 paper "No Silver Bullet"; and (4) today's thoughts on the 1986 assertion, "There will be no silver bullet within ten years."

    With this hands-on guide, you'll learn how to write effective, idiomatic Python code by leveraging its best and possibly most neglected features. Author Luciano Ramalho takes you through Python's core language features and libraries, and shows you how to make your code shorter, faster, and more readable at the same time.Many experienced programmers try to bend Python to fit patterns they learned from other languages, and never discover Python features outside of their experience. With this book, those Python programmers will thoroughly learn how to become proficient in Python 3.This book covers:Python data model: understand how special methods are the key to the consistent behavior of objectsData structures: take full advantage of built-in types, and understand the text vs bytes duality in the Unicode ageFunctions as objects: view Python functions as first-class objects, and understand how this affects popular design patternsObject-oriented idioms: build classes by learning about references, mutability, interfaces, operator overloading, and multiple inheritanceControl flow: leverage context managers, generators, coroutines, and concurrency with the concurrent.futures and asyncio packagesMetaprogramming: understand how properties, attribute descriptors, class decorators, and metaclasses work"

    The book is broken into two parts, the first deals with security-related reverse engineering and the second explores the more practical aspects of reverse engineering.

    Today, our entire modern way of life, from communication to commerce to conflict, fundamentally depends on the Internet. And the cybersecurity issues that result challenge literally everyone: politicians wrestling with everything from cybercrime to online freedom; generals protecting the nation from new forms of attack, while planning new cyberwars; business executives defending firms from once unimaginable threats, and looking to make money off of them; lawyers and ethicists building new frameworks for right and wrong. Most of all, cybersecurity issues affect us as individuals. We face new questions in everything from our rights and responsibilities as citizens of both the online and real world to simply how to protect ourselves and our families from a new type of danger. And yet, there is perhaps no issue that has grown so important, so quickly, and that touches so many, that remains so poorly understood.In Cybersecurity and CyberWar: What Everyone Needs to Know�, New York Times best-selling author P. W. Singer and noted cyber expert Allan Friedman team up to provide the kind of easy-to-read, yet deeply informative resource book that has been missing on this crucial issue of 21st century life. Written in a lively, accessible style, filled with engaging stories and illustrative anecdotes, the book is structured around the key question areas of cyberspace and its security: how it all works, why it all matters, and what can we do? Along the way, they take readers on a tour of the important (and entertaining) issues and characters of cybersecurity, from the "Anonymous" hacker group and the Stuxnet computer virus to the new cyber units of the Chinese and U.S. militaries. Cybersecurity and CyberWar: What Everyone Needs to Know� is the definitive account on the subject for us all, which comes not a moment too soon.What Everyone Needs to Know� is a registered trademark of Oxford University Press.
