    The rapid maturation of PHP has created a skeptical population of users from more traditional enterprise languages who question the readiness and ability of PHP to scale, as well as a large population of PHP developers without formal computer science backgrounds who have learned through the hands-on experimentation while developing small and midsize applications in PHP. While there are many books on learning PHP and developing small applications with it, there is a serious lack of information on scaling PHP for large-scale, business-critical systems. Schlossnagle's Advanced PHP Programming fills that void, demonstrating that PHP is ready for enterprise Web applications by showing the reader how to develop PHP-based applications for maximum performance, stability, and extensibility.

    It takes a fairly traditional approach, emphasizing problem solving, design, and programming as the core skills of computer science. However, these ideas are illustrated using a non-traditional language, namely Python. Although I use Python as the language, teaching Python is not the main point of this book. Rather, Python is used to illustrate fundamental principles of design and programming that apply in any language or computing environment. In some places, I have purposely avoided certain Python features and idioms that are not generally found in other languages. There are already many good books about Python on the market; this book is intended as an introduction to computing. Features include the following: *Extensive use of computer graphics. *Interesting examples. *Readable prose. *Flexible spiral coverage. *Just-in-time object coverage. *Extensive end-of-chapter problems.

    And considering that the "one man" is Neal Stephenson, "the hacker Hemingway" (Newsweek) -- acclaimed novelist, pragmatist, seer, nerd-friendly philosopher, and nationally bestselling author of groundbreaking literary works (Snow Crash, Cryptonomicon, etc., etc.) -- the word is well worth hearing. Mostly well-reasoned examination and partial rant, Stephenson's In the Beginning... was the Command Line is a thoughtful, irreverent, hilarious treatise on the cyber-culture past and present; on operating system tyrannies and downloaded popular revolutions; on the Internet, Disney World, Big Bangs, not to mention the meaning of life itself.

    With a little test kitchen know-how (and relentless testing and re-testing), we found ways to make naturally fast dishes even faster, and traditionally slow-cooked dinners a weeknight option.

    Featuring techniques not taught in any certification prep or covered by common defensive scanners, this book integrates social engineering, programming, and vulnerability exploits into a multidisciplinary approach for targeting and compromising high security environments. From discovering and creating attack vectors, and moving unseen through a target enterprise, to establishing command and exfiltrating data--even from organizations without a direct Internet connection--this guide contains the crucial techniques that provide a more accurate picture of your system's defense. Custom coding examples use VBA, Windows Scripting Host, C, Java, JavaScript, Flash, and more, with coverage of standard library applications and the use of scanning tools to bypass common defensive measures.Typical penetration testing consists of low-level hackers attacking a system with a list of known vulnerabilities, and defenders preventing those hacks using an equally well-known list of defensive scans. The professional hackers and nation states on the forefront of today's threats operate at a much more complex level--and this book shows you how to defend your high security network.Use targeted social engineering pretexts to create the initial compromise Leave a command and control structure in place for long-term access Escalate privilege and breach networks, operating systems, and trust structures Infiltrate further using harvested credentials while expanding control Today's threats are organized, professionally-run, and very much for-profit. Financial institutions, health care organizations, law enforcement, government agencies, and other high-value targets need to harden their IT infrastructure and human capital against targeted advanced attacks from motivated professionals. Advanced Penetration Testing goes beyond Kali linux and Metasploit and to provide you advanced pen testing for high security networks.

     Current medical wisdom advises that anyone suffering from diabetes or prediabetes should eat a low-carbohydrate, high-fat diet. But in this revolutionary book, Cyrus Khambatta, PhD, and Robby Barbaro, MPH, rely on a century of research to show that advice is misguided. While it may improve short-term blood glucose control, such a diet also increases the long-term risk for chronic diseases like cancer, high blood pressure, high cholesterol, chronic kidney disease, and fatty liver disease.The revolutionary solution is to eat a low-fat plant-based whole-food diet, the most powerful way to reverse insulin resistance in all types of diabetes: type 1, type 1.5, type 2, prediabetes, and gestational diabetes.As the creators of the extraordinary and effective Mastering Diabetes Method, Khambatta and Barbaro lay out a step-by-step plan proven to reverse insulin resistance-the root cause of blood glucose variability- while improving overall health and maximizing life expectancy. Armed with more than 800 scientific references and drawing on more than 36 years of personal experience living with type 1 diabetes themselves, the authors show how to eat large quantities of carbohydrate-rich whole foods like bananas, potatoes, and quinoa while decreasing blood glucose, oral medication, and insulin requirements. They also provide life-changing advice on intermittent fasting and daily exercise and offer tips on eating in tricky situations, such as restaurant meals and family dinners. Perhaps best of all: On the Mastering Diabetes Method, you will never go hungry.With more than 30 delicious, filling, and nutrient-dense recipes and backed by cutting-edge nutritional science, Mastering Diabetes will help you maximize your insulin sensitivity, attain your ideal body weight, improve your digestive health, gain energy, live an active life, and feel the best you've felt in years.
