Blog postI am currently in my tenth year as a Disney Technology Cast Member. As the tenth year is a milestone year at the company, I have spent some time reflecting on my time here, my career, and where I want to go over the next decade. My conclusion is that I cannot imagine working anywhere else. This post describes some of my reasons why.
Background Technically, I do not work for Walt Disney World, though that is the easiest way to explain it to people. In fact, I am employed by Disney Park -
Blog postIn 2005, the .NET Framework had its 1.1 SP1 release and was relatively stable. Visual Studio .NET 2003 was a solid release. C# was being widely adopted throughout the industry. Selecting it for a project cost me my job, and nearly sunk my career as a software developer.
Compaq ActiveAnswers This was almost two decades ago, so I feel comfortable discussing it now. I was working as a software developer at Hewlett-Packard in Nashua, New Hampshire, USA. HP had recently merged with Compaq, -
Blog postI recently celebrated nine years as a software developer at Walt Disney World in Florida. It is the longest I have ever stayed with a single company in my nearly 30-year software development career. Not coincidentally, it has also been one of my most rewarding. In this post I will describe a philosophy of Guest Service known as Walt Disney’s Four Keys Basics. In a follow-up, I will discuss how to apply these basics to software development.
A Brief Note In case you are wondering, none -

Blog postIf you want to have a more positive impact to those around you in your daily life, personal or professional, I have two words of advice: slow down. I will explain the details and benefits in this post.
Background I get asked from time to time what kinds of advice I have for people looking to get ahead, be taken seriously, or just be thought of more positively. After an experience I had with some young men at church, one of biggest suggestions is this: slow down.

Blog postI normally ignore unsolicited emails from recruiters. They are almost never a good match, and feel as though they are “shotgun” email blasts sent to hundreds or thousands of people. This one was different, though. It had the word “Disney” in the subject line.
A Little Background Let me set the stage for you so that you have some context. The first thing you need to know is that my entire family consists of what we lovingly call “Disney nuts.” For years I had a Spaceship Earth antenna -
Blog postIf you think the key to avoiding perjury is simply to be honest, I have a story for you. Leaving one of my early programming jobs and being honest almost landed me in jail.
I have avoided telling this story publicly because of an irrational fear of repercussions. However, more than twenty years have passed since the events in this post, and I have taken care not to name names. So, I think I will be fine.
I Am a Developer! Back in 1995 I landed my second paid programming gig. I -
Blog postOne of my blind spots when creating apps with the Ionic Framework is adding a side-menu after the fact. Even after using it for so many years, it seems I always need to look up how to do it. So I created this post to remind me (and you) how to create an effective Ionic Menu with and without an Ionic Split Pane View in an Ionic Angular application.
This article is adapted from my book series on Developing Mobile Applications with Ionic and Angular: Ionic Framework - Idea to App Store. -
Blog postIt took some experimenting and creating a video, but I finally figured out what the difference is between the three types for an ion-menu component in the Ionic Framework.
The ion-menu is the Ionic component that implements a side-menu. As with most other Ionic container components, it can contain a header with a toolbar and title, along with some ion-content. The typical side-menu consists of a list of pages, made from an ion-list of ion-items.
Type The menu can be customized -
Blog postOne of the key features of Progressive Web Applications is the ability for them to function without a network connection. Angular makes it really easy to turn any web app into a PWA. Believe it or not, though, having a PWA that works offline does come with some downside, primarily due to it caching much of your application. If your users are expecting current data, but your service worker is serving cached data, there could be some confusion. So in this post, I will show you how to provide a

Blog postDeploying to app stores is painful. It is hard. There are many aspects of deploying apps that you must get right, and the process differs between the Apple App Store and the Google Play Store. This post describes my experience with that process, and why I became so captivated with Progressive Web Applications (PWAs).
Note: This is an excerpt from my book, Developing Progressive Web Applications with Angular (and Ionic)
Deploying to the App Store As I said, it is hard. Here are
