Getting Started with Estimote Nearables and Xamarin

I've been a big fan of Estimote (and beacons in general) for awhile now, but only just recently had a chance to finally play around with their nearables, dubbed Estimote Stickers. These stickers are similar to beacons, except that their primary purpose is to be attached to physical objects, and in addition to proximity also broadcast more contextual information about the object.

Testing Xamarin Apps: Getting Started with xUnit

It's no secret that I'm a big proponent of testing, and lately I've been getting a lot of questions around how to approach getting started and what technologies to use.

In this post I'm going…

One approached I've used in the past is to throw some lines in my app's startup code like this: foreach (var family in UIFont.FamilyNames) foreach (var fontName in UIFont…

Developing Your First Apple Watch App

Apple's new wearable is finally making it out to users, which means now is the time to start building apps for it! First, let's take a look at the different pieces that make up a watch app. Watch App: While you might think that this is where most of your app logic will live, watch apps actually offload all real work to their parent apps. The watch app itself effectively contains just the user interface and…
