    Robinson – a former body–builder, one–time bouncer, and lifelong fight connoisseur – takes readers on a no–holds–barred plunge into what fighting is all about, and what fighters live for. If George Plimpton had muscles and had been choked out one too many times––this is the book he could have written.When Robinson and his fellow fighters mix it up, they live completely for the moment: absorbed in the feel of muscles slippery with sweat; the metallic tang of blood mingling with saliva in the mouth; the sweet, firm thud of taped knuckles impacting flesh. They fight because it feels good. They fight because they want to win. And even if they get their asses kicked, they fight because they love fighting.Fight is part encyclopedia, part panegyric to fighting in all its forms and glory. Robinson's narrative – told in his trademark tough–guy, stream–of–consciousness noir voice – punctuates this explanatory compendium of the fighting world. From wrestling, jiu–jitsu, boxing and muay thai to bar fighting, hand–to–hand combat, prison fighting and hockey fights, from the greatest movie fight scenes to how to throw the perfect left hook, Fight is a scene–by–scene tour of the bloody but beautiful underworld that is the art of fighting.With his aficionado's enthusiasm and fast–paced, addictive voice, Robinson's Fight combines compelling text with beautiful photographs to create an illustrated book as edgy and interesting as it is gorgeous.

    One slogan of Perl is that it makes easy things easy and hard things possible. "Intermediate Perl" is about making the leap from the easy things to the hard ones.Originally released in 2003 as "Learning Perl Objects, References, and Modules" and revised and updated for Perl 5.8, this book offers a gentle but thorough introduction to intermediate programming in Perl. Written by the authors of the best-selling "Learning Perl," it picks up where that book left off. Topics include: Packages and namespacesReferences and scopingManipulating complex data structuresObject-oriented programmingWriting and using modulesTesting Perl codeContributing to CPANFollowing the successful format of "Learning Perl," we designed each chapter in the book to be small enough to be read in just an hour or two, ending with a series of exercises to help you practice what you've learned. To use the book, you just need to be familiar with the material in "Learning Perl" and have ambition to go further.Perl is a different language to different people. It is a quick scripting tool for some, and a fully-featured object-oriented language for others. It is used for everything from performing quick global replacements on text files, to crunching huge, complex sets of scientific data that take weeks to process. Perl is what you make of it. But regardless of what you use Perl for, this book helps you do it more effectively, efficiently, and elegantly."Intermediate Perl" is about learning to use Perl as a programming language, and not just a scripting language. This is the book that turns the Perl dabbler into the Perl programmer.

He's also living at home since his marriage broke up, and he's just collected the wrong child from school.But one night Connor stumbles on a route back to the top, via a beautiful model, two deranged psychopaths, a multi-million pound publishing fraud, true love and utter heartbreak...

    

    In the Mastering Emacs ebook you will learn the answers to all the concepts that take weeks, months or even years to truly learn, all in one place.“Emacs is such a hard editor to learn”But why is it so hard to learn? As it turns out, it's almost always the same handful of issues that everyone faces.If you have tried to learn Emacs you will have struggled with the same problems everyone faces, and few tutorials to see you through it.I have dedicated the first half of the book to explaining the essence of Emacs — and in doing so, how to overcome these issues:Memorizing Emacs’s keys: You will learn Emacs one key at a time, starting with the arrow keys. To feel productive in Emacs, it’s important you start on an equal footing — without too many new concepts and keys to memorize. Each chapter will introduce more keys and concepts so you can learn at your own pace. Discovering new modes and features: Emacs is a self-documenting editor, and I will teach you how to use the apropos, info, and describe system to discover new modes and features, or help you find things you forgot! Customizing Emacs: You don’t have to learn Emacs Lisp to alter a lot of Emacs’s functionality. Most changes you want to make are possible using Emacs’s Customize interface and I will show you how to use it efficiently. Understanding the terminology: Emacs is so old it predates almost every other editor and all modern user interfaces. I have an entire chapter dedicated to the unique terminology in Emacs; how it is different from other editors, and what that means to you.

    But the principles and practices of software architecting–what the authors call the “science of hard decisions”–have been evolving for cloud, mobile, and other shifts. Now fully revised and updated, this book shares the knowledge and real-world perspectives that enable you to design for success–and deliver more successful solutions. In this fully updated Second Edition, you will: Learn how only a deep understanding of domain can lead to appropriate architecture Examine domain-driven design in both theory and implementation Shift your approach to code first, model later–including multilayer architecture Capture the benefits of prioritizing software maintainability See how readability, testability, and extensibility lead to code quality Take a user experience (UX) first approach, rather than designing for data Review patterns for organizing business logic Use event sourcing and CQRS together to model complex business domains more effectively Delve inside the persistence layer, including patterns and implementation.
