20 Free Ebooks On Ruby, Javascript, Perl And Python

Wanted to learn four of the big ones from amongst the programming languages? CodeKill Group bring these ebooks which can help you get started! 

Together Ruby, JavaScript, Perl and Python make for four of the most popular programming languages being used nowadays. Learning this languages is a priority for every programmer, even if they are hackers. So, with that in mind, here CodeKill present you, 20 of the best free ebooks on these languages. Ruby 1. The Bastards Book of Ruby: The Bastards Book of Ruby is an introduction to programming and its practical uses for journalists, researchers, scientists, analysts, and anyone else whose job is to seek out, make sense from, and show the hard-to-find data. 2. Clever Algorithms: Implementing an Artificial Intelligence algorithm is difficult. Algorithm descriptions may be incomplete, inconsistent, and distributed across a number of papers, chapters and even websites. This can result in varied interpretations of algorithms, undue attrition of algorithms, and ultimately bad science. This book is an effort to address these issues by providing a handbook of algorithmic recipes drawn from the fields of Metaheuristics, Biologically Inspired Computation and Computational Intelligence, described in a complete, consistent, and centralized manner. These standardized descriptions were carefully designed to be accessible, usable, and understandable. Most of the algorithms described were originally inspired by biological and natural systems, such as the adaptive capabilities of genetic evolution and the acquired immune system, and the foraging behaviors of birds, bees, ants and bacteria. An encyclopedic algorithm reference, this book is intended for research scientists, engineers, students, and interested amateurs. Each algorithm description provides a working code example in the Ruby Programming Language. 3. Data Structures and Algorithms with Object-Oriented Design Patterns in Ruby: This book is about the fundamentals of data structures and algorithms--the basic elements from which large and complex software artifacts are built. To develop a solid understanding of a data structure requires three things: First, you must learn how the information is arranged in the memory of the computer. Second, you must become familiar with the algorithms for manipulating the information contained in the data structure. And third, you must understand the performance characteristics of the data structure so that when called upon to select a suitable data structure for a particular application, you are able to make an appropriate decision. This book also illustrates object-oriented design and it promotes the use of common, object-oriented design patterns. The algorithms and data structures in the book are presented in the Ruby programming language. Virtually all the data structures are presented in the context of a single class hierarchy. This commitment to a single design allows the programs presented in the later chapters to build upon the programs presented in the earlier chapters. 4. Learn Ruby the Hard Way: Learn Ruby The Hard Way is a translation of the original "Learn Python The Hard Way" to teaching Ruby, with the translation done by Rob Sobers. "Learn Python The Hard Way" has taught hundreds of thousands worldwide how to code in Python, and this book uses the same proven method for Ruby. When you are done with this book you will have the skill to move on to other books about Ruby and be ready to understand them. 5. Learn to Program: This is the second edition of the original Learn to Program by Chris Pine. It has been updated with more current examples and has been writtent to suit the most recent version of the Ruby language. 6. Mr. Neighborly’s Humble Little Ruby Book: Mr. Neighborly's Humble Little Ruby Book covers the Ruby language from the very basics of using puts to put naughty phrases on the screen all the way to serving up your favorite web page from WEBrick or connecting to your favorite web service. Written in a conversational narrative rather than like a dry reference book, Mr. Neighborly's Humble Little Ruby Book is an easy to read, easy to follow guide to all things Ruby. 7. Programming Ruby: This book is a tutorial and reference for the Ruby programming language. Use Ruby, and you'll write better code, be more productive, and enjoy programming more. 8. Ruby Best Practices: Practice Ruby is a website that started in 2010. It contains various articles on the Ruby Programming language, which have come from the community itself. Javascript 1. Eloquent Javascript: Eloquent JavaScript is a book providing an introduction to the JavaScript programming language and programming in general. 2. Essential JavaScript Design Patterns For Beginners: This book consists of an amalgamation of modern and classic design patterns. 3. The Node Beginner Book: The aim of this document is to get you started with developing applications with Node.js, teaching you everything you need to know about "advanced" JavaScript along the way. It goes way beyond your typical "Hello World" tutorial. Perl: 1. Beginning Perl: This book is for those new to programming who want to learn with Perl. You will find it easier if you already have some basic programming experience, but the material covered can be mastered by anyone with just a text editor, some common sense and a computer. If you want to learn how to program with Perl and then find out how far you can go with it, this is the book for you. An excellent companion on any programming course. 2. Higher-Order Perl: The book was published on 8 March 2005. Copies are available in bookstores in the U.S. and Europe, and from online booksellers. A second printing became available in August 2005 only. 3. Impatient Perl: When you just have to learn Perl and time is of the essence, this book is your best friend. 4. Modern Perl: Modern Perl is suitable for programmers of every level. It's more than a Perl tutorial—only Modern Perl focuses on Perl 5.12 and 5.14, to demonstrate the latest and most effective time-saving features. Only Modern Perl explains how and why the language works, to let you unlock the full power of Perl. Python: 1. A Byte of Python: 'A Byte of Python' is a free book on programming using the Python language. It serves as a tutorial or guide to the Python language for a beginner audience. If all you know about computers is how to save text files, then this is the book for you. 2. How to Think Like a Computer Scientist – Learning with Python: How to Think... is a Free Book available under the GNU Free Documentation License. Readers are free to copy and distribute the text; they are also free to modify it, which allows them to adapt the book to different needs, and to help develop new material. 3. Invent Your Own Computer Games with Python: “Invent Your Own Computer Games with Python” is a free book (as in, open source) and a free eBook (as in, no cost to download) that teaches you how to program in the Python programming language. Each chapter gives you the complete source code for a new game, and then teaches the programming concepts from the example. 4. Learn Python The Hard Way: This book tells you how the hard way is actually the easy and the right way to learn Python. 5. Non-Programmer’s Tutorial for Python 3: This wikibook covers various aspects of Python that you may have been looking for. Shivam Kotwalia, CodeKill
