Hello Micronaut

From some of my previous posts, you can get the idea that I promote the idea of developing maintainable code rapidly. So I was pretty excited when I learned that the same group that was responsible for Grails was working on a similar project for Web Services. Hello, Micronaut.

In this post, I provide an introduction to the Micronaut framework and its features to provide a foundation for you to try it out yourself.

Tastes Like Burning: An Example of ARKit and iOS Particle Systems

We have reached a peak in computer science: I can make fire come out of my face. Apple has made it simple with an iPhone X to track a userโ€™s face and use a particle systems file to add special effects.

In this post, I will demonstrate how to โ€œbreathe fireโ€ using Xcode 9.4.1, Swift 4.1.2, and iOS 11.4.1 on my iPhone X. For this tutorial, you will need a physical device with a TrueDepth camera. The completed project is available on GitHub.

A lot of iOS tutorials start off with creating a Single View Application. That can get boring. Luckily in this article….

Improving Performance in Enterprise Web Applications

Zach Gardner Articles, Opinion, Programming

Every team that builds a large web application can generally pick from the following: delivering application functionality on time, with high quality, or high performance. Teams can pick one or two of the options, but they can’t pick all three.

Most teams opt to only focus on performance if and when it becomes a problem. This, unfortunately, can be far too late for some projects. Anyone who has been in the industry can empathize with both sides of the equation – choosing to defer performance concerns, as well as seeing the negative impact it can have on the success of the product as a whole.

It is a lesson I’ve learned from hard experience, so I want to make sure others can learn from my mistakes. In this post, I suggest a handful of principles that help to find a happy medium for delivering high-quality software applications while focusing on performance.

Significant improvements can be realized even if only one or two of the principles are applied. Applying all of them, of course, will produce the best results.

Into the Core

The client Iโ€™m currently assisting has begun to move applications from more monolithic architecture into a more modern, cloud-based architecture. The organization is a bit of a .NET anomaly in that it is a company thatโ€™s primarily Java, yet has some .NET.

So even though Microsoft has a list of framework tools (such as Azure Service Fabric and Azure App Service), itโ€™s fair to say that asking a primarily Java-focused company to use those tools could be an uphill battle. This is where .NET Standard and .NET Core have come to the rescue.

I work with a ton of smart people and Iโ€™m pretty amazed at how fast they can pick up on things from reading. I, however, cannot really understand it fully until I touch it. So letโ€™s build a quick RESTful Web API step by step to see how challenging it is. Weโ€™ll be using .NET Standard, .NET Core, and ASP.NET Core.
