Newbies Introduction to Ruby on Rails

Note: This tutorial is intended to newbies only who want to kick-start web development with Ruby on Rails. I will just share links to different resources and give tips based on my experience which may help you starting development with Ruby on Rails.

Installation and Prerequisites

Just like any other framework ruby on rails framework has its own development environment, before diving into installations of environment I would recommend if you have  planned to use Window operating system for ruby on rails development please read Rails Development on Windows. Seriously and switch to linux/unix based operating system. If you still insist to carry on with Windows go ahead with my Best wishes.

You can find complete installation guide of Ruby on Rails on GoRails website (there are other websites too). I will recommend installing RVM instead of rbenv and installing it from source.  GoRails guides also include installing Git, MySQL/Postgres complete the installation process. You might get errors while installation please do check your OS and version before starting installation process.

Ruby Language

Once you have set up your installations and environment start with ruby language basics I would recommend The Little Book of Ruby by Huw Collingbourne. Don’t memorise anything just practice basic syntax, data structures, condition statements, loops modules and Classes. Since we have already installed ruby as well as created a project of rails (in above GoRails guide) your can either go to project root and open a console or write your program in a .rb file and run it with ruby keyword as mentioned in book.

Ruby on Rails Framework

You are familiar with Ruby language basics now it is time to start getting your hands on Ruby on Rails. You will find numerous tutorial on getting started with Rails, but RUBY ON RAILS TUTORIAL by Michael Hartl is the most comprehensive guide for newbies. It covers details at granular level starting from Zero to Deployment it includes everything. There are other good resources as well like RailsCastsDriftingRuby, RailsTutorial, but if you are newbie I would highly recommend finishing Ruby on Rails Tutorial book by Micheal Hartl thoroughly first and then look elsewhere like RailsCasts (very good for topic specific tutorials) as it will make your Rails framework understanding in-depth.

Development Environment

Development environment contains your machine, tools, settings, configurations etc. Make your development environment as smooth as possible use .bashrc, tumx, terminal settings aliases to amplify your concentration. Have strong grip over terminal commands. Choose any suitable text editor I personally use Sublime Text in development and vim or emacs in production mode. Look at StackOverFlow’s survey for Most Popular Developer Environments by Occupation.

Be Open Source 

Ruby on Rails is an open source framework and it has very large open source community, as a beginner you will get lots of help from open source community in term of different gems, git, gist, stack overflow etc. Don’t forget to contribute back once you have a good grip.

Follow Tech Talks

Ruby and Ruby on Rails framework has large community of developers across the world. There are many conferences being held across the world on Ruby language and Ruby on Rails framework both. RubyConf and RailsConf are two of the most popular conferences in Ruby on Rails world. Do follow tech talks in these conferences particularly from speakers David Heinemeier, Sean Griffin, Mike Perham, Aaron Patterson and people who are at the forefront of Ruby language and Ruby on Rails framework development. Look at 11 TOP INTERNATIONAL RUBY ON RAILS CONFERENCES AND EVENTS 2017. Also one particularly article I really like every Rails developer to read is The Rails Doctrine by DHH.

Never Stop Learning

Once you have develop basics of ruby on rails I would recommend having some DevOps and Front end frameworks like ReactJS, VueJS  skills as well. Do explore topics like High Availability, Consistency, Scaling RDBS, NoSQL etc and  regularly read engineering blogs of tech giants like Google, Twitter, Microsoft and Amazon etc.

If you are newbie to Ruby on Rails development and want any suggestions or help do ping me on twitter @alihaider907.

Happy Learning 😛

How pair programming helped me focus more

I am a big advocate of pair programming as I always feel more productive doing tasks in a pair because it tends to be a Get Things Done kind of attitude. Followings are reasons why I believe pair programming can help you more productive at certain stages

  • The purpose of two programmers sitting on a single workstation is not always to get output greater than output of both individuals but to get the critical work done i.e, setting up your first deployment environment, debugging a rare and critical bug, code merge or code reviews etc
  • If pair consists of a senior developer with a junior developer the follow of knowledge from senior to junior developer really help junior developer to learn. This is what I have experienced while working almost a year with Waqas Farooq he be a Geek and I as new-grad
  • Many a time I have experienced that Unforced Errors like unintentionally making changes to another file, environment variables not loading in production are greatly reduced when a pair sit-down on a single workstation
  • Almost everyone uses social media be it Facebook, Twitter, Reddit, Hacker News etc during work to get some comfort and once your dive into it then it become difficult to get out of this comfort zone. But when you sit together with your fellow programmer the follow of work never stop and social media and other hurdles never come in your way you just keep going until you hit the finish line.
  • Concept of pair programming gets redefined under remote working environment as you are no longer sitting together physically but still you can be on a single workstation by the means of online realtime collaboration tools i.e. screen sharing

I hope my experience would help promoting pair programming culture at your workplace.

Happy Pair Programming 🙂
