    Elite organizations such as army special forces, SWAT teams , the marines and more, all require a minimum amount of pull-ups as a prerequisite for anyone to join their training programs.But, although pull-ups target first of all the back, you usually end up feeling them only on your arms, right? Heck, your neck feels tense every time you perform them and you wonder what you are doing wrong.The truth is that there is more to pull ups than just lifting yourself up and down from a bar. It's quite common for people to be doing a ton of reps without any impressive results. This book will first of all teach you that you have to bring your reps down while polishing your technique. "Huh? Lower my reps? Isn't that bad for building muscle?"When it comes to pull-ups, no it's not. Pull-ups are a completely different animal than most of the exercises out there. Eight good reps are better than fifteen crappy ones as you will learn.Doing your reps the wrong way can have you wondering why your back doesn't grow. Learn to do them the right way and people will go "Damn!" when they see you topless. How to Carve a Gymnast's Back with Pull Ups gives you all the tools you will ever need in order to turn this exercise into the muscle building monster it really is. There are 6 techniques in the book to help you maximize the muscle growth of your back during pull ups:1.Learn how to activate your lats. First you got to feel your lats before even starting to do a single rep. That way you make every rep count and you also release tension from your neck and shoulders.2.Switch your back muscles on before you pull. This is a middle step between hanging and pulling and many people neglect it along with the extra back activation it provides. 3.Lift yourself up without excessively using your arms. Ever felt your biceps and forearms pumped up from pull ups but not your back? By having your elbows close to your ribs as you pull, you can say hello to your new, pumped back!4.Bring your chest to the bar for maximum contraction of the lats. Ninety-nine out of a hundred people can't do this and their back growth clearly indicates it. This is the technique that takes your back from "meh, OK" to "WOW!".5.Control your body on the way down. An uncontrollable rep is a rep wasted. You damage your joints and even miss on extra back growth.6.Visualize your lats contracting. This is the cherry on top of the cake and you get to eat it too. Internal cues like visualizing have helped many people increase exercise performance and you can now do the same with your pull ups.You can start performing these techniques immediately, wherever you are and begin witnessing your back become as powerful and muscular as an Olympic Gymnast's.

Don't blame me when people start complaining that you're blocking their sun once you master these techniques.. You've been warned.

    Although companies of every kind have successfully implemented his original design ideas across hundreds of systems, these insights have never before appeared in print.Based on first principles in software engineering and a comprehensive set of matching tools and techniques, Löwy's methodology integrates system design and project design. First, he describes the primary area where many software architects fail and shows how to decompose a system into smaller building blocks or services, based on volatility. Next, he shows how to flow an effective project design from the system design; how to accurately calculate the project duration, cost, and risk; and how to devise multiple execution options.The method and principles in Righting Software apply regardless of your project and company size, technology, platform, or industry. Löwy starts the reader on a journey that addresses the critical challenges of software development today by righting software systems and projects as well as careers-and possibly the software industry as a whole. Software professionals, architects, project leads, or managers at any stage of their career will benefit greatly from this book, which provides guidance and knowledge that would otherwise take decades and many projects to acquire.

    More than three years in development and subjected to numerous industry reviews, the 85 patterns in this full-color book provide the most successful and proven design techniques to overcoming the most common and critical problems to achieving modern-day SOA. Through numerous examples, individually documented pattern profiles, and over 400 color illustrations, this book provides in-depth coverage of:• Patterns for the design, implementation, and governance of service inventories–collections of services representing individual service portfolios that can be independently modeled, designed, and evolved.• Patterns specific to service-level architecture which pertain to a wide range of design areas, including contract design, security, legacy encapsulation, reliability, scalability, and a variety of implementation and governance issues.• Service composition patterns that address the many aspects associated with combining services into aggregate distributed solutions, including topics such as runtime messaging and message design, inter-service security controls, and transformation.• Compound patterns (such as Enterprise Service Bus and Orchestration) and recommended pattern application sequences that establish foundational processes. The book begins by establishing SOA types that are referenced throughout the patterns and then form the basis of a final chapter that discusses the architectural impact of service-oriented computing in general. These chapters bookend the pattern catalog to provide a clear link between SOA design patterns, the strategic goals of service-oriented computing, different SOA types, and the service-orientation design paradigm.This book series is further supported by a series of resources sites, including soabooks.com, soaspecs.com, soapatterns.org, soamag.com, and soaposters.com.

    The Department of Justice’s endeavors to capture him on video surveillance likewise came up empty, because he rarely left his modest row house at 2230 Ocean Pkwy., in Brooklyn, New York. He was silent and reclusive to a fault. And by the time the public got their first look at him in 1970 (following an arrest on a trumped-up charge that was never prosecuted) he was already the most powerful mafia boss in the country, controlling a crew of 800 mafiosi, who oversaw nearly 50 criminal and legitimate businesses, which netted his crime family over $1 billion in annual revenue. Yet few even knew his name, let alone his story. Now, for the first time ever, the true story of Carlo Gambino is told in full, gory detail. Gambino: The Rise, A Novel Based on a True Story, unveils the intricate machinations of Gambino’s ascent, from poor, immigrant stowaway, to billionaire boss of America’s most deadly and elite crime family. On this journey, we meet such celebrity hoods as Charlie “Lucky” Luciano, Al “Scarface” Capone, Meyer Lansky, Vito Genovese, and Albert “The Mad Hatter” Anastasia… all of whom became pawns on Gambino’s Machiavellian chess set. Gambino’s story is a rags to riches tail of the bloodiest kind, which explores the dichotomies of family, wealth, and power within the mafia environment. With its careful scrutiny of mob business and brutality, Gambino: The Rise will undoubtedly draw comparisons to Mario Puzo’s timeless classic, The Godfather. But this is to be expected, especially when Puzo’s fictional crime patriarch, Vito Corleone, was based on none other than Carlo Gambino. Gambino: The Rise is a historical novel for the ages that will leave readers shell-shocked with every flip of the page, until its earth-shattering and climactic end.

    But the cosmos has something different in store... From Chapter One: THE ARRIVAL "I didn’t even really see it. I felt it and there was a flash of brilliant green and blue light. But I had no idea what was going on. All I knew was that something had entered my room before I could get the window closed, the force of it knocking me to the floor." "It was standing there, no taller than my knee. It was green, with little pointy ears and a little face. I didn’t even know whether it was a he or a she.
