20 Years of Ruby

20 Years of Ruby (https://blog.jetbrains.com/ruby/2015/12/20-years-of-ruby/)
As hard to believe as it is, 20 years ago the first public version of Ruby saw the light of day. Ruby 0.95 was announced by Yukihiro Matsumoto, now widely known as Matz. Over these 20 years a lot of developers have discovered Ruby and fell in love with it, including us at JetBrains. Hopefully there are many more younger people who will do the same one day. Hurray to the whole Ruby community who has helped make this history happen!   More…

Git
(https://git-scm.com/)
Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

Git is easy to learn and has a tiny footprint with lightning fast performance. It outclasses SCM tools like Subversion, CVS, Perforce, and ClearCase with features like cheap local branching, convenient staging areas, and multiple workflows.

GitHub
(https://github.com/)
GitHub is where people build software. More than 11 million people use GitHub to discover, fork, and contribute to over 27 million projects.
GitHub is a Web-based Git repository hosting service. It offers all of the distributed revision control and source code management (SCM) functionality of Git as well as adding its own features. Unlike Git, which is strictly a command-line tool, GitHub provides a Web-based graphical interface and desktop as well as mobile integration. It also provides access control and several collaboration features such as bug tracking, feature requests, task management, and wikis for every project.

GitHub offers both plans for private repositories and free accounts,^[4] which are usually used to host open-source software projects.  As of 2015, GitHub reports having over 9 million users and over 21.1 million repositories, making it the largest host of source code in the world.

Simply pick your configuration and develop your app. No need to spend valuable development time on system setup and maintenance. You can create, build and run any development stack in seconds. We maintain it, you control it.

All the freedom you’d expect
Workspaces are powered by Docker Ubuntu containers that give you full freedom over your environment, including sudo rights. Do a git push, compile SASS, see server output, and Run apps easily with the built-in Terminal and Runners.

Language tools that make you smarter
Cloud9 supports more than 40 languages, with class A support for PHP, Ruby, Python, JavaScript, Go, and more

This is your Workspace
We maintain it, you control it

Web development was never so easy

Nitrous.io
(https://www.nitrous.io/)
Professional developers use Nitrous to create, snapshot and share development environments in the cloud

Consistent Development Environments in the Cloud

With Nitrous, developers can utilize pre-built development environment templates from the Nitrous standard library, or use their companies’ own private templates . This makes it incredibly easy to keep standard templates for a particular client’s project, or to collaborate and share among teams.

Scalable, Compliant Infrastructure

Nitrous gives you complete control of your workstation and projects. You have root access to each one, and you can interact with them as you would any machine. In addition, Nitrous provides robust controls to maintain security and data protection in the cloud.

 

Isolated and Replicable Projects

Start with a fresh Nitrous box every time you begin a new project instead of running into installation and configuration issues from previous projects on your local machine or managed corporate VM. Save your base environment to reuse again, and share it with team members.

PhantomJS (http://phantomjs.org/)
PhantomJS is a headless WebKit scriptable with a JavaScript API. It has fast and native support for various web standards: DOM handling, CSS selector, JSON, Canvas, and SVG.

Ruby in 20 Minutes
(https://www.ruby-lang.org/en/documentation/quickstart/)
This is a small Ruby tutorial that should take no more than 20 minutes to complete. It makes the assumption that you already have Ruby installed.

Ruby From Other Languages
(https://www.ruby-lang.org/en/documentation/ruby-from-other-languages/)When you first look at some Ruby code, it will likely remind you of other programming languages you’ve used. This is on purpose. Much of the syntax is familiar to users of Perl, Python, and Java (among other languages), so if you’ve used those, learning Ruby will be a piece of cake.

This document contains two major sections. The first attempts to be a rapid-fire summary of what you can expect to see when going from language X to Ruby. The second section tackles the major language features and how they might compare to what you’re already familiar with.

Vim (http://www.vim.org/index.php)
Vim is a highly configurable text editor built to enable efficient text editing. It is an improved version of the vi editor distributed with most UNIX systems.
Vim is often called a “programmer’s editor,” and so useful for programming that many consider it an entire IDE. It’s not just for programmers, though. Vim is perfect for all kinds of text editing, from composing email to editing configuration files.

Sublime Text 2 (https://www.sublimetext.com)
“Sublime Text is a sophisticated text editor for code, markup and prose. You’ll love the slick user interface, extraordinary features and amazing performance.”

Introduction
This is a small Ruby tutorial that should take no more than 20 minutes to complete. It makes the assumption that you already have Ruby installed. (If you do not have Ruby on your computer install it before you get started.)

Interactive Ruby
Ruby comes with a program that will show the results of any Ruby statements you feed it. Playing with Ruby code in interactive sessions like this is a terrific way to learn the language.

Ruby from Other Languages

Ruby Essentials
(http://www.techotopia.com/index.php/Ruby_Essentials)
Ruby Essentials is a free on-line book designed to provide a concise and easy to follow guide to learning Ruby.

Ruby is a flexible and intuitive object-oriented programming language. From modest beginnings in Japan where it rapidly gained a loyal following, the popularity of Ruby has now spread throughout the programming world.

This surge in popularity can, in no small part, be attributed to the introduction and wide adoption of the Ruby on Rails framework. It is difficult, however, to get the most out of Ruby on Rails without first learning something about programming in Ruby, and this is where Ruby Essentials comes in.

Ruby Essentials is a free on-line book designed to provide a concise and easy to follow guide to learning Ruby. Everything from installing Ruby and the basics of the language through to topics such as arrays, file handling and object-oriented programming are covered, all combined with easy to understand code examples which serve to bridge the gap between theory and practice.

Ruby Essentials is intended to be of equal use both to those experienced in other programming languages and to novices who have chosen Ruby as their “first programming language”.

10 Minutes to Your First Ruby Application
(http://neurogami.com/content/neurogami-10_minutes_to_your_first_Ruby_app/)
Write a useful Ruby program that demonstrates key language concepts.

So you’ve discovered the grace and power of Ruby and you’re ready to explore the subtle but important ideas behind its elegance. Follow this tutorial to create a small, useful Ruby application. As Ruby is primarily an object-oriented language with classes and objects, you can jump right in and create a class to encapsulate behavior. The instructions begin with a simple version of the application, and then expand it. Along the way, you will learn what makes Ruby tick.
The example application will serve two purposes:

1. Demonstrate some features of Ruby
2. Do something useful in the process

A word on the title: Were you to write this code yourself, assuming some moderate Ruby knowledge, it probably wouldn’t take more than 10 minutes. Once you learn how Ruby works and understand what sort of code it enables, you’ll find that you can whip up useful utilities in short order. Of course, a walk-through of such code will take a bit more than 10 minutes if you’re new to the language.

Ruby on Rails
(http://rubyonrails.org/)
Ruby on Rails is an open-source web framework that’s optimized for programmer happiness and sustainable productivity. It lets you write beautiful code by favouring convention over configuration.

Tens of thousands of Rails applications are already live. People are using Rails in the tiniest part-time operations to the biggest companies.

Rails was created in 2003 by David Heinemeier Hansson and has since been extended by the Rails core team and more than 4,000 contributors.

The latest version is 4.2.0
