Best Ruby Computer Programming

The first title to focus squarely on object-oriented Ruby application design, Practical Object-Oriented Design in Ruby will guide you to superior outcomes, whatever your previous Ruby experience. Understand how object-oriented programming can help you craft Ruby code that is easier to maintain and upgrade Decide what belongs in a single Ruby class Avoid entangling objects that should be kept separate Define flexible interfaces among objects Reduce programming overhead costs with duck typing Successfully apply inheritance Build objects via composition Design cost-effective tests Solve common problems associated with poorly designed Ruby code. Your descriptions are so vibrant and vivid that I’m rediscovering the truth buried in OO principles that are otherwise so internalized that I forget to explore them. “As a self-taught programmer, this was an extremely helpful dive into some OOP concepts that I could definitely stand to become better acquainted with! “Meticulously pragmatic and exquisitely articulate, Practical Object Oriented Design in Ruby makes otherwise elusive knowledge available to an audience which desperately needs it. Not only is the book 100% on-point, Sandi has an easy writing style with lots of great analogies that drive every point home.”. “While Ruby is an object-oriented language, little time is spent in the documentation on what OO truly means or how it should direct the way we build programs. Here Metz brings it to the fore, covering most of the key principles of OO development and design in an engaging, easy-to-understand manner. “Distilling scary OO design practices with clear-cut examples and explanations makes this a book or novices and experts alike. It’s jam-packed with great nuggets of practical advice and coding techniques that you can start applying immediately in your projects.”. –Kevin Berridge, software engineering manager, Pointe Blank Solutions, and organizer, Burning River Developers Meetup. This book is excellently written, well-organized, with lucid explanations of technical programming concepts.”. “Metz’s take on the subject is rooted strongly in theory, but the explanation always stays grounded in real world concerns, which helped me to internalize it. “Whether you’re just getting started in your software development career, or you’ve been coding for years (like I have), it’s likely that you’ll learn a lot from Ms. Metz’s book. Sandi Metz has thirty years of experience working on projects that survived to grow and change. She now writes code every day as a software architect at Duke University, where her team solves real problems for customers who have large object-oriented applications that have been evolving for more than fifteen years.

Hartl explains how each new technique solves a real-world problem, and then he demonstrates it with bite-sized code that’s simple enough to understand, yet novel enough to be useful. Install and set up your Rails development environment, including pre-installed integrated development environment (IDE) in the cloud Go beyond generated code to truly understand how to build Rails applications from scratch Learn testing and test-driven development (TDD) Effectively use the Model-View-Controller (MVC) pattern Structure applications using the REST architecture Build static pages and transform them into dynamic ones Master the Ruby programming skills all Rails developers need Create high-quality site layouts and data models Implement registration and authentication systems, including validation and secure passwords Update, display, and delete users Upload images in production using a cloud storage service Implement account activation and password reset, including sending email with Rails Add social features and microblogging, including an introduction to Ajax Record version changes with Git and create a secure remote repository at Bitbucket Deploy your applications early and often with Heroku. It’s an amazing piece of work and, unusually, walks you through building a Rails app from start to finish with testing. “For the self-motivated reader who responds well to the ‘learn by doing’ method and is prepared to put in the effort, this comes highly recommended.”. As an undergraduate, completely detached from industry, this book showed me how to use version control, how to write tests, and, most importantly–despite the steep learning curve for setting up and getting stuff running–how the end result of perseverance is extremely gratifying. “It doesn’t matter what you think you will be developing with in the future or what the framework du jour is; if you want to learn how to build something, there is no better place to start than with this tutorial. And for all the ‘non-technical’ people out there who want to see their ideas come to life, who are considering hiring contractors, paying for a class, or ‘founder dating’ in the search for a technical co-founder: stop. Forget about your idea for a short while and immerse yourself in this tutorial to learn what it takes to put something together. “Without a doubt, the best way I learned Ruby on Rails was by building an actual working app. I used Michael Hartl’s Ruby on Rails(TM) Tutorial , which showed me how to get a very basic Twitter-like app up and running from scratch. “The author is clearly an expert at the Ruby language and the Rails framework, but more than that, he is a working software engineer who introduces best practices throughout the text.”. His prior experience includes writing and developing RailsSpace, an extremely obsolete Rails tutorial book, and developing Insoshi, a once-popular and now-obsolete social networking platform in Ruby on Rails. He is a graduate of Harvard College, has a Ph.D. in Physics from Caltech, and is an alumnus of the Y Combinator entrepreneur program.

In Service-Oriented Design with Ruby and Rails, Paul Dix introduces a powerful, services-based design approach geared toward overcoming all these challenges. Build highly scalable, Ruby-based service architectures that operate smoothly in the cloud or with legacy systems Scale Rails systems to handle more requests, larger development teams, and more complex code bases Master new best practices for designing and creating services in Ruby Use Ruby to glue together services written in any language Use Ruby libraries to build and consume RESTful web services Use Ruby JSON parsers to quickly represent resources from HTTP services Write lightweight, well-designed API wrappers around internal or external services Discover powerful non-Rails frameworks that simplify Ruby service implementation Implement standards-based enterprise messaging with Advanced Message Queuing Protocol (AMQP) Optimize performance with load balancing and caching Provide for security and authentication.

The new C++11 standard allows programmers to express ideas more clearly, simply, and directly, and to write faster, more efficient code. The C++ Programming Language, Fourth Edition, delivers meticulous, richly explained, and integrated coverage of the entire language—its facilities, abstraction mechanisms, standard libraries, and key design techniques. C++ abstraction, including classes, class hierarchies, and templates in support of a synthesis of traditional programming, object-oriented programming, and generic programming. This fourth edition makes C++11 thoroughly accessible to programmers moving from C++98 or other languages, while introducing insights and techniques that even cutting-edge C++11 programmers will find indispensable. The recipient of numerous honors, including The National Academy of Engineering 2018 Charles Stark Draper Prize for Engineering “for conceptualizing and developing the C++ programming language , Dr. Stroustrup is a member of the National Academy of Engineering, an AT&T Fellow, an AT&T Bell Laboratories Fellow, an IEEE Fellow, and an ACM Fellow.

Regular expressions are an extremely powerful tool for manipulating text and data. Mastering Regular Expressions will help you navigate the minefield to becoming an expert and help you optimize your use of regular expressions. Mastering Regular Expressions , Third Edition, now includes a full chapter devoted to PHP and its powerful and expressive suite of regular expression functions, in addition to enhanced PHP coverage in the central "core" chapters. "There isn't a better (or more useful) book available on regular expressions." "A real tour-de-force of a book which not only covers the mechanics of regexes in extraordinary detail but also talks about efficiency and the use of regexes in Perl, Java, and .NET...If you use regular expressions as part of your professional work (even if you already have a good book on whatever language you're programming in) I would strongly recommend this book to you." - James Mohr, Linux Magazine, April 2007 Jeffrey Friedl was raised in the countryside of Rootstown, Ohio, and had aspirations of being an astronomer until one day he noticed a TRS-80 Model I sitting unused in the corner of the chem lab (bristling with a full 16K of RAM, no less).

Using the Smarter Way to Learn method, you actually learn HTML/CSS, you don’t just read about it. Read the reviews that call The Smarter Way of learning fun, involving, frustration-free, and confidence-building. Then, if you want to go beyond reading about HTML & CSS and actually learn the skills, do it the smarter way.

After reading a short chapter, you go to my website and complete twenty interactive exercises. Many learners hit a wall when they try to understand advanced concepts like variable scope and prototypes. But the fault lies with the authors, coding virtuosos who lack teaching talent. Thanks to the interactive exercises on my website, you'll always understand and remember everything necessary to confidently tackle the next concept. "I've signed up to a few sites like Udemy, Codecademy, FreeCodeCamp, Lynda, YouTube videos, even searched on Coursera but nothing seemed to work for me. It's how you wind up satisfied, confident, and proud, instead of confused, discouraged, and defeated. The exercises keep you focused, give you extra practice where you're shaky, and prepare you for each next step. But, as Amazon reviewer James Toban says, when you get to the end of the book, you've built "a tower of JavaScript." But if you're new to programming, more than a thousand five-star reviews are pretty good evidence that my book may be just the one to get you coding JavaScript successfully. "Mark Myers' method of getting what can be...difficult information into a format that makes it exponentially easier to consume, truly understand, and synthesize into real-world application is beyond anything I've encountered before." My professional focus is on using technology to reduce the effort and tedium of learning, primarily through interactivity. I'm developing the "A Smarter Way to Learn" series on programming, a collection of instructional books paired with online interactive exercises. Along with my wife Judy and our two politically-active cats, I live in Taos, NM, where I cook under the ghostly supervision of Marcella Hazan, read extensively, play showboat frisbee once a week, and long for more episodes of "Breaking Bad."
