A full Rails application probably has less total code than the XML you'd need to configure the same application in other frameworks. With this book you'll learn how to use "ActiveRecord" to connect business objects and database tables. No more painful object-relational mapping. Just create your business objects and let Rails do the rest. You'll learn how to use the "Action Pack" framework to route incoming requests and render pages using easy-to-write templates and components. See how to exploit the Rails service frameworks to send emails, implement web services, and create dynamic, user-centric web-pages using built-in Javascript and Ajax support. There are extensive chapters on testing, deployment, and scaling. You'll see how easy it is to install Rails using your web server of choice (such as Apache or lighttpd) or using its own included web server. You'll be writing applications that work with your favorite database (MySQL, Oracle, Postgres, and more) in no time at all. You'll create a complete online store application in the extended tutorial section, so you'll see how a full Rails application is developed---iteratively and rapidly. Rails strives to honor the Pragmatic Programmer's "DRY Principle" by avoiding the extra work of configuration files and code annotations. You can develop in real-time: make a change, and watch it work immediately. Forget XML. Everything in Rails, from templates to control flow to business logic, is written in Ruby, the language of choice for programmers who like to get the job done well (and leave work ontime for a change). Rails is the framework of choice for the new generation of Web 2.0 developers. Agile Web Development with Rails is the book for that generation, written by Dave Thomas (Pragmatic Programmer and author of Programming Ruby) and David Heinemeier Hansson, who created Rails.

    Every complete program uses a consistent style, and as programs are analyzed, styles and standards are further explained. Whenever possible, the authors develop the principle of a subject before they introduce the language implementation so the student understands the concept before dealing with the nuances of C++. In addition, a vast array of figures and tables visually reinforce key concepts. By integrating software engineering principles and encouraging the student to resist the temptation to immediately code, the text builds a solid foundation in problem solving.

    His groundbreaking revelations shed light not just on business but on the way every human being acts and lives around the world. Rapaille’s breakthrough notion is that we acquire a silent system of Codes as we grow up within our culture. These Codes—the Culture Code—are what make us American, or German, or French, and they invisibly shape how we behave in our personal lives, even when we are completely unaware of our motives. What’s more, we can learn to crack the Codes that guide our actions and achieve new understanding of why we do the things we do. Rapaille has used the Culture Code to help Chrysler build the PT Cruiser—the most successful American car launch in recent memory. He has used it to help Procter & Gamble design its advertising campaign for Folger’s coffee – one of the longest-lasting and most successful campaigns in the annals of advertising. He has used it to help companies as diverse as GE, AT&T, Boeing, Honda, Kellogg, and L’Oréal improve their bottom line at home and overseas. And now, in The Culture Code, he uses it to reveal why Americans act distinctly like Americans, and what makes us different from the world around us. In The Culture Code, Dr. Rapaille decodes two dozen of our most fundamental archetypes—ranging from sex to money to health to America itself—to give us “a new set of glasses” with which to view our actions and motivations. Why are we so often disillusioned by love? Why is fat a solution rather than a problem? Why do we reject the notion of perfection? Why is fast food in our lives to stay? The answers are in the Codes. Understanding the Codes gives us unprecedented freedom over our lives. It lets us do business in dramatically new ways. And it finally explains why people around the world really are different, and reveals the hidden clues to understanding us all.

    R has traditionally been difficult for non-statisticians to learn, and most R books assume far too much knowledge to be of help. R for Everyone is the solution. Drawing on his unsurpassed experience teaching new users, professional data scientist Jared P. Lander has written the perfect tutorial for anyone new to statistical programming and modeling. Organized to make learning easy and intuitive, this guide focuses on the 20 percent of R functionality you'll need to accomplish 80 percent of modern data tasks. Lander's self-contained chapters start with the absolute basics, offering extensive hands-on practice and sample code. You'll download and install R; navigate and use the R environment; master basic program control, data import, and manipulation; and walk through several essential tests. Then, building on this foundation, you'll construct several complete models, both linear and nonlinear, and use some data mining techniques. By the time you're done, you won't just know how to write R programs, you'll be ready to tackle the statistical problems you care about most.

    Kudos to the writer.” ~Rajeev Patel, an Amazon top 1000 reviewerSummary:Vedgarh, an ancient home of purebred Aryans, is a secret world in modern times where the chants of Vedic Mantras mingle with Acoustics and Applied Physics, the Maharathi warriors fight alongside Indian Army Veterans, and Ancient Daivi Astras join hands with modern Sonic Weapons. Gurukul, Vedgarh’s school, is the sole protector and preacher of sacred Vedic scriptures and Celestial powers. It is due to these powers that Vedgarh is the only corner of the universe where Dwapara Yuga persists even today. Vedgarh is in a continuous state of war with the rising dark powers of Kaliyuga: The Asuras. If Vedgarh falls, the Universe will drown in the darkness of Kaliyuga forever. Sitting on the verge of yet another war with Asuras, Vedgarh is suffering from a lack of warriors. Seeing no promising talents in the Gurukul, Vedgarh opens its gates for modern science and selects a few from the contemporary world to work on a grand mission: a mission to harmonize ancient Vedic powers with modern scientific miracles, to prepare an army of warriors equipped with ancient and modern techniques of fighting, and to invoke Daivi Astras (celestial weapons of Gods) using light and compact modern Sonic weapons. Get ready to witness Vedic Scholars, Physicists, Professors, Sacred Gurus, Ancient warriors, and Indian Army soldiers preparing for the greatest upcoming war of Daivi Astras in the history of mankind.
