Taking a Look at Entity Framework Queries pt 1 (.NET Framework)

If you aren’t familiar, Entity Framework is a powerful open-source object-relational mapping (ORM) framework. Its initial release was back in 2008, so it has grown and evolved quite a bit. I have been using it now, very regularly, for about four years and just wanted to bring to light some tips and the missteps that I have encountered during that time.
I think the most important thing when using EF(Entity Framework) is to be aware of the work it is doing on your behalf.  The best way to see what EF is doing is to simply log it, and for me, that means the output window in Visual Studio, not the database, as you will see, EF does a lot.  So, that being said, it is actually much easier to do than you might expect, and in my mind, there are…

First Look: Microsoft Healthcare Bot

On February 7th, 2019, Microsoft announced the availability of a new SaaS chatbot offering designed for use in the healthcare industry.  They designed it to be a very fast-to-market conversational AI with built-in healthcare language models, terminology, and be compliant with security standards in the industry (HIPAA, ISO 27001, ISO 27018, CSA Gold, GDPR).
Mid-March I began my exploration into this offering and started building my first “Scenario.”  Once you have created a bot, you are delivered to a new portal and are quickly presented with a showing of pre-baked templates for you to modify and make your own. At the time there were three available and four listed as coming soon.

I decided to start with the Provider Lookup scenario.  Once I created the scenario, I was then taken to a well-designed CMS tool for building it.  The tool displays the…

Design Patterns – Factory Method

The Factory Method design pattern is a creational pattern for simplifying construction of similar objects through means of subclasses and a superclass or interface/class relationships. Makes perfect sense right?  Alright, more simply it helps reduce the complexity of your code when it comes to creating similar objects and taking action with them.
So… where is this pattern helpful?  For the sake of this post, imagine you run a popular website where users can come to get rewards for activities or purchases they have made, and that your site currently only lets users receive payouts from PayPal. More than likely the application will have a lot of code written with only PayPal in mind, scattered throughout the code base with conditional behaviors at every step of the way. Now, let’s imagine that times are changing and your users would rather be paid…

Facebook AR Studio – How to: Use Tap Gestures to Change Effect Materials

Introduction
Recently I was given the opportunity to spend some time playing with Facebook’s awesome AR (Augmented Reality) Studio. I worked through Facebook’s quick start tutorial and created a mustache effect in no time. Immediately I was hooked, it was all so easy to use. AR Studio does the heavy lifting for the face tracking, so really all you need is a texture to make your first filter. So after the first and second basic filter, I wanted to make something more dynamic, I wanted to change the filter on tap, and suddenly my progress screamed to a halt. All of a sudden the documentation and instructions lacked what I needed. I looked through the tutorials and found out how to add scripts, but not how to change materials, or bind the events to specific objects. After hours of experimentation I…
