Ran into an interesting problem today in which a method in one of my classes happened to have the same name as a method on my testing framework. I'm pasting a lot of code but highlighting the important details with comments. Contract require_relative './exceptions' require_relative './fulfillment_…
UPDATE: I got it to work. Use inotify on your host machine to watch the directory for changes and run docker exec <container> circusctl restart <circus_process> And since MAC doesn't have inotify, we can use fswatch. brew install fswatch Then we can watch a directory…
The new operator is often misunderstood and improperly used by programmers just learning JavaScript. This operator "creates an instance of a user-defined object type or of one of the built-in object types that has a constructor function". Let's focus on one part a a time. In the sentence…

The Workflow Let me describe the workflow we were trying to accomplish. We wanted to run tests on every merge into 'master'. If the tests pass, we wanted the code to be automatically pushed to a staging server. Once we verify staging is working properly, we want to merge that…
Check out this XKCD comic and think about what repetitive tasks you could shave seconds off of throughout your day. Props go out to Josh Wyatt for showing me the world of .bash_profile time-saving techniques. The first thing to do is make it convenient to add new shortcuts to…
This is going to be a simple demonstration of using Test Driven Development practices to solve a toy problem. We will use Node for running Javascript in our console. Grunt task-runner for automation. Mocha for our testing framework. Chai for our assertion library. The only thing you need to do…
Now that we know what Docker is and have it installed, let's look at how we can use it to deploy an app. We are working on a project now as part of HackReactor's curriculum. Our project involves a MySQL database and ExpressJS API on the back-end handling basic CRUD…
docker run ubuntu /bin/echo "Hello World!" Hello World! Simple enough, but the power of this command is amazing and allows us to do incredible things. This is what goes on behind the scenes when that command is run: Docker searches your local machine's cache to see if…
