The Azure cloud platform is vast and it can be difficult to determine the best option given unique requirements. This video discusses six options within the wide world of Microsoft Azure including Virtual Machines (IaaS), App Services (PaaS), Function Apps (FaaS), AKS (KaaS), Logic Apps (?aaS), and Service Fabric (PaaS).

For each option, Keyhole Software Consultant Zach Gardner introduces the pros, cons, optimal use cases, and tips for success with each Azure approach based on his experience.

This 40-minute video was recorded in November 2019 at a Keyhole Software internal employee Lunch & Learn event featuring Keyhole Consultant Zach Gardner…

Maps and Entities and JPA, OH MY!

Ryan McCullough Articles, Development Technologies & Tools, Programming Leave a Comment

A client I’m working with has an email templating system that needs an upgrade! The current design utilizes a denormalized table that needed to grow a column every time a new unique token is needed. After a review of the offerings through JPA, I was happy to see that JPA had some support for java.util.Map through joins through a variety of the @MapKey annotation.

In this post, I’ll demonstrate the less frequently used methodology of applying and populating a Map of entities using a single table and a composite key.

More on Accessibility-First Programming

Todd Horn Articles, Development Technologies & Tools, Opinion, Programming Leave a Comment

A few months back, Aaron wrote about the high-level aspects of Accessibility-First Programming, its importance, and specific strategies and tools for applying it within your software development process. It included insights and suggestions for Color and Contrast, Focus Management, the use of ARIA tags and attributes, and testing strategies and tools – all of which are important things to consider. 

In this post, we’re going to dig in a little deeper on three of those topics that I used on my last project: ARIA, the WCAG and what is needed for compliance, and some design principles of accessible design. We’ll include insights and further reading on relevant topics to help you better understand how to implement accessibility-first programming in your own development.

How to Create a Dystopian Future at Home with Python, OpenCV, and Microsoft Azure

Facial recognition is both amazing and horrifying. Some amazing things it can do is the ability to find missing children or seniors, using your face to unlock your phone, and being able to board an airplane faster.

In this blog post, I want to highlight some powerful tools and platforms that allow you to create distributed facial recognition systems with OpenCV and Azure’s Cognitive Services. By the end of this post, you will have a working face detector using OpenCV that can communicate with Azure’s Cognitive Services.

I used Python 3.7.4 and pip 19.2.3 for this project. You can view the code from this blog at https://github.com/dcandre/Dystopian-Future-At-Home.

Go To SQL

In between projects here at Keyhole, I’ve been tasked with applying a relational database access and mapping framework in the Go language.

In this post, I go step by step to create a Postgres relational database, then perform CRUD operations against it in the Go language.

I won’t get into the specifics of configuring Go in this blog, but you can check it out yourself here – https://golang.org/. Additionally, Keyhole’s very own David Pitt wrote an excellent primer on the subject here – https://keyholesoftware.com/2019/09/26/go-on-the-fly/.
