Step-by-step “Hello World” examples in Ruby, SQL, and Ruby on Rails
Continuing forward from Part 1 of this 3-part “Hello World” mini-series within our web and mobile development tutorials, here we'll walk through Ruby, Standard Query Language (SQL), and Ruby on Rails. If you have not yet completed steps 1–7 from Part 1, click here to go back and do so now. If you have, great, let's continue.
We're now at the point in our web and mobile development series where we'll jump right into setting up the app we'll be building step-by-step together. This will be a practical, hands-on introduction to a dozen web-app related programming languages, frameworks, and libraries. When we're done with this and the next two posts, we'll have the foundation of our app ready to receive and merge in the pretty stuff from our visual designer (which we'll do later in this series). You ready? Let's go.
A quick introduction to Embedded Ruby (a.k.a. ERB, eRuby)
Before we dive directly into Ruby on Rails app development, after reading the Ruby introduction post in this series it is worth taking a moment to understand the concept and practice of Embedded Ruby.
Introducing the app we’ll be building publicly step-by-step
At this point in our web and mobile development series I'll introduce you to the specific app we will be building together. We'll follow the steps we mentioned in my previous post “So you have an app idea. Now what?” — which means I'll attempt to actually “walk the walk” and follow my own advice.
A quick introduction to Backbone.js
A quick introduction to XML and JSON
A quick introduction to CoffeeScript
As we near the end of our high-level summaries of the basic software tools used by modern-day web developers, here in our Intro to web and mobile app development series we'll introduce you to a magnificent, fun-to-write, meta-level, and transcompiling language (i.e. converts to one language from another) called CoffeeScript.
A quick introduction to Git
At this point in our app development tutorial series we're going to take a moment to introduce Git, a version control system (VCS) that developers use to (1) collaborate with others, (2) ensure every line of code ever written on a project is saved, and (3) hook into automated testing and deployment work flows to make their jobs easier.
A quick introduction to Ruby on Rails
Moving forward with our tutorial series teaching beginners how to build modern-day apps for web and mobile devices, today we're going to take a brief, high-level look at Ruby on Rails and it's Model-View-Controller architecture to give you a better understanding of what all the fuss is about.
A quick introduction to Ruby
A quick introduction to jQuery
I've opened this series of web & mobile development tutorials with a quick look at HTML and CSS. Now it's time to dive into a scripting language that can be used for all kinds of things from running web servers, video games, and robots, to doing things in web browsers like validating forms before sending data to your back-end server (wooohooo! exciting, I know. Stay in your seat and let's do this).
A quick introduction to Cascading Style Sheets (CSS)
Continuing our series of introductory tutorials for building web and mobile applications, here we'll cover Cascading Style Sheets (CSS). CSS is intended to control the visual design of your markup (HTML) and respond to simple mouse events (e.g. hovering).
A quick introduction to Hyper Text Markup Language (HTML)
HTML has now evolved five generations and has all kinds of fancy new capabilities. It is, however, still in a slightly awkward phase because there are still some browsers that do not fully support it. This means when we use HTML5 we need have to have graceful fall-back options (which is called unobtrusive programming). We'll talk more about this in later tutorials.
