Keyhole Software is excited to announce our very own David Pitt will providing a technical workshop at the University of Arkansas Blockchain Hackathon on November 6th, 2019 from 6 – 8 PM at the Doug McMillon Innovation Studio.

The University of Arkansas will be hosting its third annual Blockchain Hackathon taking place on November 8th – 9th in downtown Fayetteville. This year will be the first time ever the Blockchain Center of Excellence (BCoE) will be opening up this event to the community, instead of only to students. The diversity of ideas, backgrounds, and skills will make for the most interesting and exciting Blockchain Hackathon to date!

Before the main event, the University of Arkansas will be conducting technical workshops leading up to the Hackathon. These workshops will offer intimate and boutique experiences every night (November 3rd – 7th) to give attendees the opportunity to hear deeper informational sessions on specific blockchains, set-up programming environments, familiarize themselves with available resources, or even do a group exercise.

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/.

Documentation: Enough Already! Not.

Documentation. I know we all hate having to create it. I don’t like writing it and feel like I always leave something out. However, our assumptions of what other developers should think we are trying to accomplish by our masterpieces of software are usually filled with potholes (sometimes big ones). The truth of the matter is that no matter how stellar your code or software is – if you’re the only one who understands how it works, it doesn’t do any good.

These are not paintings or sculptures that would live the rest of their days in a museum, untouched by human hands and just collecting dust as they run. In reality, documentation will be added to and changed as the information they describe evolves.

In this blog, we discuss two suggested strategies for the creation of useful and concise software documentation.

Imparting Knowledge And Preparing For The End Of A Contract

In this blog, I share an example of a consulting engagement that required significant knowledge transfer to new hires. We detail an approach for teaching Spring Batch to developers with no previous experience in Java or the Spring Framework.

The goal is to provide a real-world example of closing a contract, imparting knowledge with the client and their employees, and the potential issues faced in the process.
