Go On The Fly

Go “On The Fly”

David Pitt Articles, Development Technologies & Tools, Keyhole Creations, Programming, Tutorial Leave a Comment

People that know me, know that I love to fly fish and tie flies. I made up the saying โ€œTime flies when youโ€™re tying flies.โ€ It is true, just like when you are trying to solve a programming problem, time flies.

Over the past few years, we at Keyhole have utilized Docker (with assorted technologies) and have gotten up to speed on the Hyperledger blockchain framework. Something that all of these technologies have in common is the Go language. Go is the language used to implement Docker, Hyperledger, OpenShift, and many other system-level applications.

Personally, I like to peek under the hood to better understand the tools Iโ€™m using. That led me to learning about the Go language. And in my opinion, the best way to learn a language is to build something.

So, I built an application for fly tying videos. There are numerous fly tying tutorials on YouTube, so I built an application that allows them to be organized into virtual fly boxes and types.

In this blog, I will introduce you to the Go language. Weโ€™ll go over some of the key language concepts by walking through how the https://flytyerworld.com server-side API is implemented using Go.

Picking A Graph Database: ArangoDB, Neo4j, or OrientDB

John Hoestje Articles, Databases, Opinion, Programming Leave a Comment

TL;DR

– Spoiler alert! Graph databases are a great option for storing complex and highly connected data.
– In this post, I compare the benefits and risks of graph databases ArangoDB, Neo4j, and OrientDB for a client project.
– Due to the combination of performance and cost, I chose ArangoDB for my clientโ€™s needs.

Spring Batch Testing & Mocking Revisited with Spring Boot

Jonny Hackett Articles, Development Technologies & Tools, Java, Spring, Spring Batch, Spring Boot, Testing 3 Comments

Several years ago, 2012 to be precise, I wrote an article on an approach to unit testing Spring Batch Jobs. My editors tell me that I still get new readers of the post every day, so it is time to revisit and update the approach to a more modern standard.

The approach used in the original post was purely testing the individual pieces containing any business logic. Back then, we didnโ€™t have some of the mocking capabilities that we have today, so I went with an approach that made sense at the time.

However, there have been a few improvements in the past several years. One of those improvements has been the ability to Mock beans within a Spring Context. Thatโ€™s where the @MockBean annotation comes to the rescue.

React vs. Angular: A Comparison Between Two Great Options

Robert Rice Angular, Articles, Development Technologies & Tools, JavaScript, Opinion, React 2 Comments

Both React and Angular are very popular front end development frameworks. In this post, I will discuss the similarities and differences between the two, and consider when one should be used instead of the other.

React is an open-source JavaScript library introduced by Facebook to build dynamic user interfaces. It is based on JavaScript and JSX (a PHP extension) and is considered widely for developing reusable HTML elements for front-end development.

Angular is an open-source front-end development framework powered by Google. It is a part of the MEAN stack and is compatible with a large number of code editors and is considered for creating dynamic websites and web apps.

In this post, we will begin by going over the benefits of React and Angular, then break down the differences between the two frameworks using thirteen attributes. By comparing each framework side by side, it can help decide which is the best framework for your specific app project.
