Did you know there are parallels between the lighting design process in dance and software development. Victoria Gonda, our resident dance expert and software developer breaks it down for you.
DroidconSF proved to be a great conference. There were so many great things to learn, and people to meet. My experience there was definitely worthwhile.
JetBrains held its first KotlinConf, and it was a huge success. With 1200 attendees, it was a great conference to both attend and speak at. There was much to learn about the language and how it is being used.
Code reviews are helpful for maintaining code quality and exchanging knowledge. They can also be a way to boost confidence and provide another meta way of educating.
When converting Java code to Kotlin code, there’s a good chance you’ll see a bunch of double bang operators. Rather than leaving these to error, you want to make these places null safe. Here we discuss some options to handle null in Kotlin.

This year I had the goal to try speaking at conferences (or at least a MeetUp), and I accomplished that goal. Here’s the story of my journey there.
Boston just had their first Droidcon, and it was a great experience. There was a beautiful community, and so many things to learn. I was also privileged to share my first talk on the Kotlin programming language.
Learn how to use Test-Driven Development to interact with a remote JSON API using Retrofit, Moshi, and RxJava
This year we had the opportunity to teach students at Holland Christian High School about the Maker Movement, and how to become involved in it. We had a blast covering 3D modeling and printing, circuits and micro-controllers, robotics, programming, and IoT services.
Sometime you need to test how your code handles an uploaded file, but you don’t want to upload it in your test. Luckily, there’s an easy way to handle this.
With the inclusion of Action Cable in Rails 5, we can easily add WebSockets to our Rails applications. This post walks through how to set up Action Cable as a response to an action on an Active Record model.
I thought it would be awesome to start speaking at conferences, but I wasn’t sure where to start. Here’s how I prepared for my first time at the podium.
The art of dancing and the act of programming are quite similar. How so? It’s the way both dancers and programmers respond to feedback.
When using Ruby on Rails Form Helpers, it could be useful to add an autocomplete feature to fields where users might reuse data. One way to do that is to use Selectize.js to create a dropdown and populate it with data from the user model.
Looking back, I now know there are a lot of that can’t be learned from a book or tutorial. Through working with others, I was able to build on my skills in a way I wouldn’t have been able to do in isolation.
Months can be difficult to work with when they have a differing number of days. Rails helps out with #month, but you still need to use caution.
We held hosted a screening of CODE: Debugging the Gender Gap in Graves Hall on the Hope College campus, and are happy with the conversations it started about the lack of women and minorities in the computing industry. The film, and the discussion that followed emphasized two important efforts when approaching this issue: exposure and support.
Collective Idea and the Hope College Computer Science Department are working together to host a screening of CODE: Debugging The Gender Gap in Holland, MI. You are invited to gather with us to watch this film in Winants Auditorium in Graves Hall on April 18th at 7:00 pm.
Iluminate uses a combination of dance and technology to create stunning performances. Their use of wireless light technology on dark costumes creates an incredible show.
When we stub an intent, we are able to intercept it so the intent is never sent to the system, and specify how it should respond. This can be helpful in your Android tests when you need to know if an intent was sent, but you don’t actually need the Activity to start. This can be accomplished by using espresso-intents.
