FreeBSD

FreeBSD for Writing Java

Rik Scarborough Articles, Development Technologies & Tools, Groovy, Java Leave a Comment

This one is just for fun. I’ve been using FreeBSD off and on since the late 90’s when a good friend, who has since passed, introduced me to the operating system.

Recently, for personal reasons, I’ve decided to move away from the big IT providers and install FreeBSD on my primary desktop for personal use. Just so it’s clear, I still use the operating system my client uses for work, but for my own personal desktop and coding projects, I’ve decided to once again install and run FreeBSD.

This post is not a tutorial, but let’s take some time to look at using this “Unix-like” operating system for real-world situations, such as developing Java applications for fun and profit.

Updating Microservices with Netty 5, Kafka 3, and React: Whirlpool Revisited

John Boardman Articles, Development Technologies & Tools, Java, JavaScript, Microservices, React Leave a Comment

Back in 2015 and 2016, I wrote two blogs that went step by step to develop a microservice/Netty architecture with fully working code called Whirlpool.

A lot has changed in the years since, so recently I decided to come back to the project, update it with the latest versions of Kafka and Netty, and add a React UI to it (rather than the vanilla JavaScript version it used before). In addition, I also added Windows Subsystem for Linux (WSL) scripts in addition to the Mac and Linux scripts that were there before and made all of the scripts more robust.

This blog will be about the work that went into all of those updates, plus a look at the new React UI. This provides an excellent view into what it takes to update an outdated microservices application implemented with Kafka (version .9 –>3.0) and Netty (4.1.3->5.0.0-alpha2), bringing all versions up to date and adding a React UI. By the end you’ll be familiar with the latest versions of these frameworks, know some “gotchas” to avoid, as well as understand how to integrate WebSockets into React.

Markdown for Documenting

Documenting with Markdown

Rik Scarborough Articles, Development Technologies & Tools, Programming Leave a Comment

In today’s environment, we have an embarrassment of riches when it comes to documenting our applications. We have a multitude of word processors, websites with word processors built in, wikis, and notes applications galore.

So you may be wondering, is there even any point in talking about ways to document your application? I think there is. In this blog, I’ll share my documentation tool and how and why you can use it in your own projects. It’s called Markdown.

How and Why to Containerize Your Development

John Hoestje Articles, Development Technologies & Tools, Docker, Opinion, Python, Tutorial Leave a Comment

This is a tutorial for how to use the VS Code Remote-Containers extension to containerize your development environment. First, I will discuss my reasons for separating my programming environment and why virtual machines didn’t work. Then, I’ll show a simple example using a containerized Python development environment. Finally, I’ll give you my reasons why containerizing the development environment fits what I’m looking for in a solution.

Apache Camel

Spring Boot & Apache Camel: Navigating the Data Processing Desert

Matt McCandless Apache, Articles, Java, Spring, Spring Boot Leave a Comment

This article will set up a basic Spring Boot app that incorporates Apache Camel to move some sample files around.

If you are like me, you find that flat-file processing can be pretty dry. Considering what Apache Camel does, its name is very fitting. While there are plenty of reasons for the name, it definitely makes sense that Apache Camel does a lot of lugging things around for you…
