My Reaction To React

David Pitt Articles, Development Technologies & Tools, JavaScript, React, Tutorial 3 Comments

We at Keyhole have been helping our clients adopt JavaScript-based single-page applications for over five years. We have been impressed with the adoption and advancement of the ever-changing JavaScript ecosystem.

Server side, headless JavaScript (Node.js) has led to good tooling and packaging options along with server side remaining available. Additionally, the new ECMA6 standard has turned JavaScript into a viable general purpose programming language, that is arguably, on the same plane as C# or Java. It certainly has a large number of available frameworks and tooling options.

React differs from the other frameworks I’ve worked with in a handful of ways. In this blog, I will show tangible examples of React’s unique features and capabilities, particularly how it handles HTML-based Components.

Containers For .NET Developers

This is going to be the first post in a series of articles about modern tooling and techniques for building distributed systems. In this post, I will show how to use Docker for Windows to set up an ELK (Elasticsearch, Kibana, Logstash) server that we are going to use in future articles. The series is particularly geared toward traditional .NET developers. Let’s get started…

Taking A Mixed Approach To Single-Page Applications

Chris Berry Angular, Articles, Development Technologies & Tools, JavaScript, Single-Page Application Leave a Comment

A coworker came to me with a problem. The client he was working with would be building hundreds of single-page applications and all would need to be tied into a single shell application. He had first attempted to use an iFrame contained within another single-page application to display the child applications.

While this worked, he came up against another requirement: the child applications may or may not need access to data from the parent shell application.

It was at this point he came to me for suggestions. I had been playing with this exact idea for sometime; how can you manage a collection of Single-Page Applications and still share data between them?

At this point, I decided to create a hybrid solution of mixing Single-Page Applications with a server-rendered shell application. The following is the process I took for creating this solution, highlighting some of the pain points with some suggestions for further enhancements.

Adventures In Modernization: Strategy + Example Converting COBOL To Java

Dallas Monson Articles, COBOL, Consulting, Development Technologies & Tools, DevOps, Java, Keyhole Creations, Modernization, Programming, Tutorial Leave a Comment

We have consultants who specialize in moving old to new, renovating dilapidated code bases, and designing brighter futures for enterprises who have been vendor-locked for most of their existence. We have come across some repeated patterns and strategies for how to approach modernization of legacy systems. In this blog, we will cover a strategy that is very popular right now, Re-Platforming.

The basic flow of this post will be:

Introduction to Modernization
High-level definition of the Re-Platforming Strategy for Modernization
Sample of Re-Platforming using Keyhole Syntax Tree Transformer, COBOL –> Java
Additional thoughts on the value/risk of this strategy

Using RetroPie to Build Keyhole’s Gaming Console

Brad Mongar Articles, Development Technologies & Tools, Keyhole 3 Comments

You know you work at a great company when you say to your boss that there is a Linux build for the RaspberryPi that is dedicated to playing old arcade and console games…. and he agrees to buy one for the company office for the low, low price of a written blog post about it.

Keyhole Software is just such a company and this is the promised blog post. Specifically, I’ll be talking about the process I used for setting up the Raspberry Pi. I’m hoping that it will give you a guide (alongside the official documentation) for making your own gaming console!
