    You could spend years discovering solutions to them all, step by step as you encounter them. Or you can just look in here. All successful database applications are destined to eventually run into issues scaling up their performance. Peek into the future of your PostgreSQL database's problems today. Know the warning signs to look for, and how to avoid the most common issues before they even happen. Surprisingly, most PostgreSQL database applications evolve in the same way: Choose the right hardware. Tune the operating system and server memory use. Optimize queries against the database, with the right indexes. Monitor every layer, from hardware to queries, using some tools that are inside PostgreSQL and others that are external. Using monitoring insight, continuously rework the design and configuration. On reaching the limits of a single server, break things up; connection pooling, caching, partitioning, and replication can all help handle increasing database workloads. The path to a high performance database system isn't always easy. But it doesn't have to be mysterious with the right guide. This book is a clear, step-by-step guide to optimizing and scaling up PostgreSQL database servers. - Publisher.

    This book is aimed at the working Rails developer who is looking to grow and evolve Rails projects while keeping them flexible, maintainable, and robust. The focus is on pragmatic solutions which tread a “middle way” between the expedience of the Rails “golden path”, and rigid OO purity.

    With its simple commands, flags, and parameters, a well-formed command-line application is the quickest way to automate a backup, a build, or a deployment and simplify your life. As Ruby pro David Copeland explains, writing a command-line application that is self-documenting, robust, adaptable and forever useful is easier than you might think. Ruby is particularly suited to this task, since it combines high-level abstractions with "close to the metal" system interaction wrapped up in a concise, readable syntax. Moreover, Ruby has the support of a rich ecosystem of open-source tools and libraries. Ten insightful chapters each explain and demonstrate a command-line best practice. You'll see how to use these tools to elevate the lowliest automation script to a maintainable, polished application. You'll learn how to use free, open source parsers to create user-friendly command-line interfaces as well as command suites. You'll see how to use defaults to keep options simple for everyday users, while giving advanced users options for more complex tasks. There's no reason a command-line application should lack documentation, whether it's part of a help command or a man page; you'll find out when and how to use both. Your journey from command-line novice to pro ends with a look at valuable approaches to testing your apps, and includes some fun techniques for outside-the-box, colorful interfaces that will delight your users. With Ruby, the command line is not dead. Long live the command line.What You Need: All you'll need is Ruby, and the ability to install a few gems along the way. Examples written for Ruby 1.9.2, but 1.8.7 should work just as well.

    Kenner is a roller-coaster ride of sinful secrets and sweet seduction. RT Book Reviews raved that “readers who need more of Kenner’s racy, sizzling Stark novels will delight in this new series, set in the same decadent, lavish world.” And now the full series is together in one riveting ebook bundle:   SAY MY NAME ON MY KNEES UNDER MY SKIN Also includes a preview of the first book in J. Kenner’s hotly anticipated new trilogy, Dirtiest Secret!   I never let anyone get too close—but he’s the only man who’s ever made me feel alive.   Meeting Jackson Steele was a shock to my senses. Confident and commanding, he could take charge of any room . . . or any woman. And Jackson wanted me. The mere sight of him took my breath away, and his touch made me break all my rules.     Our bond was immediate, our passion untamed. I wanted to surrender completely to his kiss, but I couldn’t risk his knowing the truth about my past. Yet Jackson carried secrets too, and in our desire we found our escape, pushing our boundaries as far as they could go.   Learning to trust is never easy. In my mind, I knew I should run. But in my heart, I never felt a fire this strong—and it could either save me or scorch me forever.   Praise for J.

    Joyce Brown, President of Fashion Institute of Technology Go behind the window displays.  Behind the racks.  Two personal shoppers for Manhattan's biggest department stores have written a wildly dishy novel that goes behind the dressing rooms of New York’s fashion elite. At Frankel’s New York, the wives of billionaires and Hollywood celebrities sip champagne while stylists and tailors cater to every whim.  And one person has made it her career to help these Amex-wielding shoppers create the perfect look. Bonnie Salerno Madden knows all of her client’s preferences, whims, and fantasies.  She knows the price they paid to gain access to the salon where having Bonnie as their private shopper is a first-class ticket to being the toast of the New York high-fashion social scene. But while Bonnie is all elegance on the outside, she’s barely keeping it together on the inside.  A single mom to a special needs child, she needs her high-pressure job to care for her family.  And when that job is put in jeopardy, Bonnie will need to make some of the riskiest choices of her life to guarantee a better future for her son, and for herself.  With the opportunity to live in her own fairy tale, will Bonnie have what it takes to make the trade off?  “THE TRADE OFF is a riveting page-turner even for a non-shopper like me. The ultimate tale of New York life.”—David Patrick Columbia, newyorksocialdiary.com

    Tuesday started out like any other day – until my school became the target of a zombie attack! I tried to call my Dad, but he wouldn’t answer. So my school is about to be taken over by crazy zombies – but not if I can help it! This story is a funny adventure that is engaging for children, middle school students, and grown-ups.

    You'll read about humans who are invisible to computers, how a default password once caused a zombie apocalypse and why airlines sometimes give away free tickets. This is also a book on how to prevent, avoid and reduce the impact of such problems. Our lives are increasingly tracked, monitored and categorised by software, driving a flood of information into the vast sea of big data. In this brave new world, humans can't cope with information overload. Governments and companies alike rely on computers to automatically detect fraud, predict behaviour and enforce laws. Inflexible automatons, barely smarter than a fridge, now make life-changing decisions. Clever marketing tricks us into believing that phones, TV sets and even cars are somehow smart. Yet all those computer systems were created by people - people who are well-meaning but fallible and biased, clever but forgetful, and who have grand plans but are pressed for time. Digitising a piece of work doesn't mean there will be no mistakes, but instead guarantees that when mistakes happen, they'll run at a massive scale. The next time you bang your head against a digital wall, the stories in this book will help you understand better what's going on and show you where to look for problems. If nothing else, when it seems as if you're under a black-magic spell, these stories will at least allow you to see the lighter side of the binary chaos. For people involved in software delivery, this book will help you find more empathy for people suffering from our mistakes, and discover heuristics to use during analysis, development or testing to make your software less error prone. <

    Through concrete examples and jargon-free explanations, this book teaches you how to apply functional programming to real-life development tasks. The book includes insightful comparisons to object-oriented or imperative programming, which will allow you to ease into functional design. Moreover, you'll learn a repertoire of techniques including function chaining and pipelining, recursion, currying, binding, functional composition, lazy evaluation, fluent error handling, memoization, and much more. By the end of the book, you'll think about application design in a fresh new way.About the technologyAs web developers build increasingly complex applications in JavaScript, the code base for these projects can become exponentially larger and harder to maintain. The result? Application performance suffers, and readability and extensibility are severely compromised. For applications like these, Functional Programming provides a saner approach, allowing you to write elegant, readable code that raises the level of abstraction while being less prone to errors. Although not a "pure" functional language, JavaScript's native functional capabilities unlock access to proven functional programming techniques and practices.What's insideFoundations of functional programming and designExplore JavaScript's functional programming capabilities and the functional library ecosystemCreate more reliable code by embracing immutabilityLearn to write code that's easier to reason aboutSeparate core logic from program structure to write extensible codeAdopt a new approach to error handling and testingApply functional programming to solve real-world problemsAbout the readerReaders need to be comfortable with JavaScript programming and object-oriented design. No previous experience with functional programming is required.About the authorLuis Atencio is a Staff Software Engineer for Citrix Systems in Ft. Lauderdale, FL.
