Jason on vacation
Here at Atomic, we work to maintain our sustainable pace on a number of levels. I typically think of my pace on a weekly granularity because of our team’s iterations, invoicing cycles, and the intervening weekend breaks. There’s a rhythm in which I can feel the ebb and flow of my energy level resulting from the week’s efforts and accomplishments.
Atomic encourages employees to take a consecutive week of vacation at some point during the year, and I recently took 10 days off to travel with my wife and disconnect. Having the opportunity to disrupt the rhythm, to disconnect and re-energize, is important. But it isn’t always easy, especially for people who are deeply engaged with and care about their work (as we do here at AO). Here are a few things that can help make it work.

My current project involves an Ember.js web application and a JSON+HAL API, and we recently wanted to let administrative users upload an XML file, sourced from a different system, to make filling out a form easier. We didn’t want to upload the file to the API for processing on the server. Following is an example illustrating how we handled the file upload in our Ember.js app, and how we could make this work with a few other file formats.
1. The Upload
Let’s pretend we want to make it easy to upload a list of user information into the application. I’m going to illustrate a method using a file input element for the upload interface. There are other options, like drag & drop, but this met our users’ needs and was simple to implement.

Here are a few tools we’re using on my current project, a non-trivial Ember.js application, to do just that.

I recently had the opportunity to travel up to the fall career fair at my alma mater, Michigan Technological University, with fellow MTU alum and Atomic developer Jeanette Head. We had a great visit. It was exciting to be back on campus looking for engaged, smart software developers to join our team, and I left seriously impressed by the number of great connections we made.
If you’re wondering how to get my attention at a job fair, or when applying for a position at Atomic Object in general, here are a few hints. Read more on How to Get My Attention at a Job Fair…
The boundaries between our digital world and physical world blur a little more every day. Our houses and cars are becoming increasingly controlled by computers and connected to the internet at large.
As a software developer and driving enthusiast, I’m particularly interested in the intersection of cars and software. I’m excited by a large number of the improvements in vehicle control and utility these changes have enabled. The stability control system in the Nissan GT-R, for example, is astoundingly robust. Naturally, then, I’m curious about what modern control systems and vehicle communication channels might enable enterprising enthusiasts and makers to accomplish.
But there is a darker side to the connected world as well: people with malicious intent are increasingly able to take advantage of the same systems. Our cars are hackable. The potential impact depends on the vehicle and whether the hacker has physical access to it, but the possibilities range from merely inconvenient to downright dangerous.

Karlin Fox and I have been using RubyMotion and ReactiveCocoa to build an iPad application for our current project. We’ve enjoyed the different paradigm and the way we’re able to stream data through our application. Adapting TouchDB live queries to ReactiveCocoa signals has been particularly rewarding.
But what about unit testing our iOS app? Unit testing in iOS has matured a lot in the past few years, and RubyMotion brings testing along from the start of a new project. However, development paradigms like FRP have a dramatic effect on how we test, what we test, and what tools we choose to build our tests.
Mocking vs. Real Objects
We’ve been alternating between mocking out signals and creating real signals we can instrument in our unit tests. Each method has its advantages.

RubyMotion promises to bring the clarity and concise syntax of Ruby to iOS and OS X development. ReactiveCocoa’s aim is to help reduce complexity by deriving state instead of declaring it. Sounds like a great combination, right?
There are some complications. First, the documentation and examples almost all use the RAC and RACAble macros provided by ReactiveCocoa, something we can’t use from RubyMotion. Bummer. And RubyMotion’s bridgesupport doesn’t allow us to call Objective-C methods that take blocks typed as id. Rats. Fortunately these can be overcome, thanks to some helpful folks on the internet, so let’s get started.

I’m currently working on an Ember.js web application that is a basic CRUD app with a twist — we don’t know all of the form fields or model attributes ahead of time, but rely on a JSON document to specify the names and types of attributes for which we need to render form controls. This presents some interesting challenges, the most significant being that our input elements don’t know what to bind their value to until they are instantiated.
After trying a few different approaches, we settled on using a pair of observers to accomplish what a more direct binding could not in this scenario. One observer watches the input’s
value property and updates the remote property value, and the other observer watches the remote property and updates the input’s
Cut to the chase and check out the jsbin example, or read on for a few more details.
(This example uses Ember.js 1.0.0-RC.1, and we are using the same general solution in 1.0.0-RC.3.)

Taking notes has been a part of my life since high school, in one form or another, but the tools I’ve used have varied quite a bit. Recently, a couple of my current project teammates and I have been trying out Mou for rapid note-taking during meetings and capturing decisions we make along the way. There are a few things that have made it a really good fit.
I even used it to write this blog post:

It’s not every day that a new meetup group springs up in Grand Rapids, but it’s not an altogether uncommon occurrence, either. What is uncommon is the start of a group that gets me personally excited and draws a sizable crowd.
It happened with the GR Web Dev group in early 2011, and now it’s happening again with GR Makers.
So, what makes these groups special? Read more on The Next Great Meetup Group: GR Makers…
