Getting Started With Ruby Processing

If you're like me, you love to code because it is a creative process.

In another life, I am a musician. I've always loved music because it represents a synthesis of the concreteness of math and the ambiguity of language. Programming is the same way.

But despite the creative potential of programming, I often find myself spending days working out the kinks of HTTP requests or dealing with SSL certificates. Some part of me yearns for a purely Apollonion environment in which to use code to make something new and unseen.

Instances, Classes, and Modules, Oh My!

One of the biggest challenges of object oriented programming in Ruby is defining the interface of your objects. In other languages, such as Java, there is an explicit way to define an interface that you must conform to. But in Ruby, it's up to you.

In this post, we'll look at several ways to solve the Exercism Leap Year problem, exploring different levels of method visiblitiy and scope level along the way.

Just as in English, there are lots of ways to say the same thing in Ruby. I spend a lot of time reading and nitpicking people's code on, and I often see exercises solved in a way that could be greatly simplified if the author had only known about a certain Ruby method. Here's a look at some lesser-used methods solve a specific problem very well.

Seven Reasons I Love Minitest

The other day at our company standup, I mentioned that I was eager to
read an article on Concurrency in Minitest
that was featured in Ruby Weekly. One of my
coworkers asked: "people still use Minitest?" My reply: "you mean you're not using Minitest yet?"

I love Minitest. It's small, lightweight, and ships with Ruby. It's used by respected programmers like Aaron Patterson, Katrina Owen, Sandi Metz, and of course, DHH. Here's a look at why Minitest remains a powerful and popular choice for testing Ruby code.
