Learning Ruby by Michael Fitzgerald Pdf

You don't have to know everything about a car to drive one, and you don't need to know everything about Ruby to start programming with it. Written for both experienced and new programmers alike, Learning Ruby is a just-get-in-and-drive book -- a hands-on tutorial that offers lots of Ruby programs and lets you know how and why they work, just enough to get you rolling down the road. Interest in Ruby stems from the popularity of Rails, the web development framework that's attracting new devotees and refugees from Java and PHP. But there are plenty of other uses for this versatile language. The best way to learn is to just try the code! You'll find examples on nearly every page of this book that you can imitate and hack. Briefly, this book: Outlines many of the most important features of Ruby Demonstrates how to use conditionals, and how to manipulate strings in Ruby. Includes a section on regular expressions Describes how to use operators, basic math, functions from the Math module, rational numbers, etc. Talks you through Ruby arrays, and demonstrates hashes in detail Explains how to process files with Ruby Discusses Ruby classes and modules (mixins) in detail, including a brief introduction to object-oriented programming (OOP) Introduces processing XML, the Tk toolkit, RubyGems, reflection, RDoc, embedded Ruby, metaprogramming, exception handling, and other topics Acquaints you with some of the essentials of Rails, and includes a short Rails tutorial. Each chapter concludes with a set of review questions, and appendices provide you with a glossary of terms related to Ruby programming, plus reference material from the book in one convenient location. If you want to take Ruby out for a drive, Learning Ruby holds the keys.

Understanding Computation by Tom Stuart Pdf

Finally, you can learn computation theory and programming language design in an engaging, practical way. Understanding Computation explains theoretical computer science in a context you’ll recognize, helping you appreciate why these ideas matter and how they can inform your day-to-day programming. Rather than use mathematical notation or an unfamiliar academic programming language like Haskell or Lisp, this book uses Ruby in a reductionist manner to present formal semantics, automata theory, and functional programming with the lambda calculus. It’s ideal for programmers versed in modern languages, with little or no formal training in computer science. Understand fundamental computing concepts, such as Turing completeness in languages Discover how programs use dynamic semantics to communicate ideas to machines Explore what a computer can do when reduced to its bare essentials Learn how universal Turing machines led to today’s general-purpose computers Perform complex calculations, using simple languages and cellular automata Determine which programming language features are essential for computation Examine how halting and self-referencing make some computing problems unsolvable Analyze programs by using abstract interpretation and type systems

The Impeccable Integrity of Ruby R. by Moni Mohsin Pdf

Ruby Rauf is an idealistic, industrious scholarship student with a fixed plan. She is going to ace her exams and get a decent job so she never has to suffer the daily degradation of poverty again. Yet, when she meets the compelling actor-turned-politician Saif Haq, her world is upended. Dazzled by his charisma, inspired by his zeal, she quits her degree midway to join his campaign as his social media manager. Ruby soon discovers that politics, even with a leader as upright as Saif Haq, is a moral minefield. Diligent, sincere but desperately naïve, Ruby longs to do the right thing but struggles at first to square her innate integrity with the difficult choices her job demands. As she wades deeper into the quagmire of political intrigue and the savage world of social media, her values grow more flexible, her methods more ruthless. She out-thinks allies and rivals to deliver brilliant results. Resented and admired by her colleagues, favoured by Saif, Ruby appears unstoppable-until one day when Saif asks her to prove her loyalty by making the most painful sacrifice of all. With quicksilver dialogue, shrewd political insight and a thoughtful take on the MeToo debate, this sparkling novel reveals Moni Mohsin on top satirical form.

A Mindfulness Guide for Survival by Ruby Wax Pdf

Dear Reader, I have written this workbook for you to use as a guide on how to drop anchor when life, and the world around you, gets too daunting. It's filled with exercises and information for when you're suddenly forced to confront the hard truths or as I like to call them the BIG SIX realities – difficult emotions, uncertainty, loneliness, change, dissatisfaction and death. It isn't just about how to get through a pandemic... Or the post-pandemic fall-out. It is a WAKE UP call. One that will increase your awareness of every moment through mindfulness. So SCRIBBLE in it. DOODLE in it. Take it EVERYWHERE. No one is going to see what's inside but you. This is not just another self-help book. Think of it as an evolve-yourself book. I do hope it helps you hold the rudder straight, no matter how turbulent the waves, and that you come out the other end buoyant, with a new appreciation for the privilege of life. Love RUBY x

Practical Object-Oriented Design in Ruby by Sandi Metz Pdf

The Complete Guide to Writing More Maintainable, Manageable, Pleasing, and Powerful Ruby Applications Ruby’s widely admired ease of use has a downside: Too many Ruby and Rails applications have been created without concern for their long-term maintenance or evolution. The Web is awash in Ruby code that is now virtually impossible to change or extend. This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples. Sandi Metz has distilled a lifetime of conversations and presentations about object-oriented design into a set of Ruby-focused practices for crafting manageable, extensible, and pleasing code. She shows you how to build new applications that can survive success and repair existing applications that have become impossible to change. Each technique is illustrated with extended examples, all downloadable from the companion Web site, poodr.info. 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. Novice Ruby programmers will find specific rules to live by; intermediate Ruby programmers will find valuable principles they can flexibly interpret and apply; and advanced Ruby programmers will find a common language they can use to lead development and guide their colleagues. This guide will help you 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
