How to Authenticate an AWS Lambda Function in C#
Serverless was only first coined as a concept 8 years ago in 2012 by Ken Fromm in The future of the world is serverless. Even with the rise of cloud computing, the world still revolves around servers. That won’t last, though. Cloud apps are moving into a serverless world, and that will bring big implications for the creation and distribution of software and applications. If you come from traditional service architecture roots of on-premises or...
Build a Weight Tracker App with Node.js and PostgreSQL
Did you make any resolutions this year? One resolution I seem to make every year is to lose weight and exercise. Sometimes I even stick to it. A good way I have found to keep on track with any resolution is to record progress. There’s something about visualizing progress that helps me stay motivated. In this tutorial, you are going to create a modern Node.js application to keep track of weight measurements. We’ll use technologies...
Angular Deployment with a Side of Spring Boot
One of the more popular combinations of frontend and backend frameworks is Angular + Spring Boot. I’ve written several tutorials about how to combine the two—from keeping them as separate apps to combining them into a single artifact. But, what about deployment? Developers ask me from time-to-time, "What’s the best way to do Angular deployment?" In this tutorial, I’ll show you several options. I’ll start by showing you how to deploy a Spring Boot app...
Serverless Java with Amazon Web Services
Serverless is the next iteration in cloud management. First, we let go of having physical hardware servers and moved all of our servers into the cloud because, hey, why bother managing all that hardware? This created cloud infrastructure providers that resulted in behemoths like Amazon and Google. Now, they’re saying, why bother managing a server at all? What you really want to do is run code, right? Serverless is an architecture where code is run...
Migrate From Travis CI to GitHub Actions
Recently, a colleague pointed out that I was still configuring Travis-CI on new GitHub repos and suggested I used GitHub Actions instead. I had given Actions the ol' five-minute test when it was still in beta, but ran into a few problems and gave up. After all, I’ve been a fan of Travis-CI for a while and I had enough new things to learn at the time. Still, if GitHub Actions lives up to the...
Vue Login and Access Control the Easy Way

Whiteboarding for Developers: Yes, You Have To
I’ve always thought developers are a pretty rare collection of individuals. We all vary in our composition; from the quiet introverts to the boisterous extroverts, from button-downed professionals to aloof loose cannons – we run the full spectrum of human personalities. However, we are unique in that we share a set of common traits that are really only understood by us. Our parents might not really know what we do: “He works with computers” Our...
Build a Secure Java Application with Apache Shiro and OAuth 2.0
Apache Shiro is a Java security framework that can perform authentication, authorization, session management, along with a host of other features for building secure applications. In this tutorial, you will build a simple Java REST application using JAX-RS. JAX-RS, like many Java APIs, is a set of interfaces, and you will need to pick an implementation. For this post, I’ll use Jersey (the reference implementation of JAX-RS), but you can use Apache CXF, RESTeasy, or...
