3D Photo Viewer for Looking Glass

The Looking Glass
I created my first Chrome extension, which is now live on the Chrome Web Store! It's built for the Looking Glass, a holographic display that let's you view three-dimensional objects without glasses. I've also opened the source to the extension on GitHub.

The Chrome extension allows you to view Facebook's "3D Photos", a feature they added in 2018 for displaying photos that include a depth map like those from phones with dual cameras, such as Apple's "Portrait Mode".

Getting Started

To use the extension, connect your Looking Glass to your computer, navigate to Facebook and open the viewer from the extension's popup menu. This will open a browser window on the Looking Glass display's screen in fullscreen mode.
Opening the Viewer
Once the viewer is open, the extension watches for any 3D Photo files being downloaded, so browse around Facebook looking for 3D Photos.  I recommend some of the Facebook groups dedicated to this topic like Facebook 3D Photos, and the Facebook 360 Community. As new photos are found, they are displayed on the Looking Glass, so you may see a few photos flash by. There are navigation controls to let you go back and look at the other photos.

Navigation

The extension allows you to navigate through the 3D photos that have been found in two ways, controls just below the Looking Glass display and controls within the extensions pop-up menu.
Navigation Controls and Focal Plane Adjustment
The navigation controls within the popup menu show you how many photos have been loaded and which photo you currently viewer.  The left and right arrow buttons allow you to navigate through the list, and the slider allows you to adjust the focal plane of the image. With the slider you can move into or out of the image, also known as dollying.

The Looking Glass display's buttons
Along with the in-browser navigation controls, you can also directly manipulate the photos using the buttons on the Looking Glass. The square and circle buttons allow you to dolly out of and into the photo, respectively. And the left and right buttons allow for navigating through the list of photos.

Simplifying logging with Maven and SLF4J (Part 2)

So in my  previous post  I explained how to simplify your logging with Maven and SLF4J. If you haven't read it yet, please do before reading more.  Since then I've discovered an easier and cleaner way to remove the secondary frameworks from your Maven dependency tree. Here's a revised overview of the steps: Decided which logging framework will be your primary, aka who will actually write to your log file. Define the dependency scope of all the secondary frameworks to be ' provided '. Configure your project to depend on drop-in replacements of each secondary framework from SLF4J. Define secondary frameworks as provided Use the dependencyManagement section for this. Its used when you might have a dependency transitively. Add dependency on SLF4J Add the following to your pom.xml Conclusion So now in only 3 steps you can redirect all your logging to your primary logging framework without changing a line of code!

My Journey to Fitness, a 5K, and my first Triathlon

At the finish line My name is Brian and Sunday I became a triathlete. My journey started ten months ago when I decided to get back into shape after 15 years of being obese and out-of-shape with some yo-yo dieting in the middle. What changed? I'll get to that. This weekend I competed in the first ever Rocketman Florida Triathlon which took place on the grounds of Kennedy Space Center at Cape Canaveral. In preparation I lost 50 lbs and 12 inches from my waist. But I'm getting ahead of myself. I'm a huge space buff. As a kid I wanted to become an astronaut. I went to Space Camp in Titusville when I was 10. Before that, I saw my first shuttle launch at 7 while on vacation. It was the final launch of the Challenger. I've written about that experience . I've seen three other launches since then including John Glenn's famous return to space as well as the final launch that ended the U.S. Shuttle Program. The idea of biking on the restricted grounds
