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.

A Quick Look at Feature Flags

Braden Niswonger Articles, Development Technologies & Tools, Programming 3 Comments

Using feature flags, also known as feature toggles or switches, is a software technique that allows segments of code to be toggled during runtime, without the need for redeploying.

Feature flags can be a powerful tool for teams utilizing continuous integration practices, allowing code to be deployed in a dormant state and enabled later on. At a basic level, they provide the ability to conditionally render or activate features at will.

In the blog, I’ll cover feature flags. We’ll start by discussing why and when we use them, and then we’ll move into an overview of what it looks like to develop with them. Let’s dive in!

Spring Batch Job Flow Using a JobExecutionDecider

In this tutorial for Spring Batch, we’re going to take a look at Programmatic Flow decisions in a Spring Batch job using Spring’s JobExecutionDecider. Spring Batch is a pretty powerful framework and this is another useful tool to have in your Spring Batch toolbox.

To demonstrate, I’ll use a scenario that came up recently while working on my client’s project. After explaining the situation and my goals, I’ll jump into a detailed, step-by-step guide. Let’s get started!

Predicting River Flow with a Supervised Learning Time Series Model

Alex Lagge Articles, Data Science, Machine Learning 1 Comment

In this blog, we will build a flow rate prediction algorithm for the Norfork River in Arkansas. Both farmers and recreationists are heavily dependent on the flow rate of the river. As the river flows faster, the risk of flooding increases and flooding can destroy crops for farmers and ruin vacations for tourists.

My goal with this flow rate prediction algorithm was to give a better idea of what the next 4 days of river flow will look like. Below, I will discuss the data science process that I underwent to make these predictions.
