A quick overview of what we'll be doing in this class.

2. A quick primer on Ruby

Let's get some background on Ruby real quick.

3. Getting your terminal and text editor set up

Make sure you have Sublime Text and the Command Line ready before moving on.

Let's get Ruby set up on your computer.

6. Debugging & continuing setting up Ruby

In this lesson, I show you how you might troubleshoot a problem during the installation process in case you run into one. (Feel free to skip this step if your installation worked fine and you just want to jump directly to coding.)

7. Command Line Crash Course

The command line can be a scary place for beginners, but there are only a handful of commands you'll need to know in order to use it including pwd, cd, and ls.

Week 2: Beginner Ruby

1. Playing with Ruby

I'm going to show you how to run your first Ruby code with the Interactive Ruby Shell (IRB).

2. Puts and your first script

I'm going to show you how to write and run your first Ruby script. Are you ready? You're about to get 20% more awesome.

3. Errors & Debugging

Ahh help! Help! Its not working! Before you freak out, let me walk you through what might go wrong when you make a typo, and how you can fix it.

4. Comments

Once you learn about comments, you'll start seeing them everywhere!

5. Numbers & Math

Let's play around with some numbers in Ruby.

6. Variables

Variables are just names for things. They're the building blocks of programming.

7. Strings & Text

Strings are another data type its important to know about in Ruby.

8. Getting User Input

Now I'll show you how to get input from people interacting with your scripts.

Week 3: Intermediate Ruby

1. Recap of Beginner Ruby

Let's review our Ruby.

2. Methods, Part 1

Methods make the world go round.

3. Methods, Part 2: Methods Strike Back

Let's learn how to use methods to set variables.

4. Methods, Part 3: Return of the Methods

I'll show you how to solve the challenge from the last lesson.

5. Reading Files

I'll show you how to read files in Ruby

6. Writing Files

I'll show you how to write to files in Ruby.

7. Copying Files

With the last two lessons (reading and writing files), you now have enough to do more advanced stuff, like write a script that copies a file from one place to another.

Week 4: Advanced Ruby

1. Logic in Ruby

True or False: Are you ready?

2. Boolean Practice

We're going to practice the truth table stuff together so that you get a better hang of it.

3. If Statements

Have you ever wondered 'What If'?

4. Else and Elsif

Else and Elsif are the other half of If.

5. Arrays

Arrays are basically lists of things in Ruby. Let me show you how to use them.

6. Loops

Loops let you do the same thing over everything in a list. Confused? They're really useful. Let me show you want I mean.

7. FizzBuzz

I'm going to challenge you with a common developer interview question.

8. FizzBuzz solution

Here's how I solved FizzBuzz.

9. More About Arrays

There was more about Arrays that I forgot to tell you.

10. Hashes

What? More stuff? This is it. Hashes are basically arrays crossed with a dictionary.
