I don’t think I have a particularly common name, but I’ve received email intended for at least four other John Rubles. This creates awkward and amusing situations. Here are some of my stories and some lessons we can take from them for implementing email-based account systems. Read more on That’s Not Your Email Address…
Build an Offline Demo of your Ember App with Ember CLI Mirage
Our client wanted a demo version of their Ember app to take to trade shows, use for sales demos, etc. Ideally, it would run on a laptop with no internet connection and not require the use of any developer tools. We decided to run the Ember app against a mocked backend.

Use ES2017’s async/await in your Ember Project Today!
After recently spending some time with C#’s async/await, I found myself wishing for the same features in JavaScript. I knew such a language feature was in the works, but it had been quite a while since I’d mentally filed it under, “Won’t it be nice when,” so I thought I’d check to see if async/await is ready for use in an Ember app.

Open Source Basics: NPM Edition
As software developers, we’ve long used third-party code in our day-to-day work, but these days, it’s much easier to find and integrate it with package managers and searchable repositories.
Inevitably, there comes a time when our unique use of a library exposes a new bug, or we find that we could almost use that sweet tool if only it did this one tiny thing differently. When that happens, we find ourselves popping open the hood and making changes to a third-party dependency. Read more on Open Source Basics: NPM Edition…

We use a popular brand of network camera as a baby monitor at home. The camera’s been great, but I have one minor quibble with its web interface. It doesn’t work very well in small window sizes. Read more on Dad-Hack: Customizing the Baby Monitor with Tampermonkey…

Parallelizing Ember Tests Across CI Workers
One of CircleCIʼs killer features is automatic test parallelization: Circle can dramatically improve your build times by divvying up your tests across multiple build containers. Split three ways, this brings our 55-minute build time down to about 23 minutes:
Those three large bars represent our automatically-balanced RSpec test suite. See that lone bar on the right side, keeping container #0 busy while #1 and #2 take a break? Those are our Ember tests. Circle is unable to automatically split them, but we can do it manually! Here’s how. Read more on Parallelizing Ember Tests Across CI Workers…
