My Reaction To React

David Pitt JavaScript, React, Technology Snapshot, Tutorial 2 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.

Quick Introduction To SQL Server Profiler

Brian Clay .NET, Databases, Technology Snapshot, Tutorial Leave a Comment

When working with SQL Server, you might run across a situation where it is just not running fast enough. While there could be many reasons for this, there are tools that can help you track down just what is going on behind the scenes. SQL Server Management Studio’s SQL Server Profiler or just (Profiler) is a tool that can be used to monitor queries run on your database.

In this blog post I’ll give a brief demonstration of the SQL Server Profiler tool. I’ll show you how to keep an eye on all the queries that are being run against your database, as well as how to use a filter to narrow your search to just slower-running queries…



Got Swagger? (i.e. How I Got My Swagger on and How You Can Too)

Aaron Diffenderfer Programming, Technology Snapshot, Tutorial Leave a Comment

Most developers attempt to ignore and put off documentation as long as possible during the development process. However, the return on investment is worth the time and effort — far more than most of us realize. This is particularly true with API documentation. 

Working with a recent client, I had the opportunity to use Swagger to document APIs and provide structure around the development process. During daily standups, I may have been known to say that my task for the day was to “get my Swagger on.” 

In this post, I want to walk you through my journey with Swagger along with general thoughts, tips, and tricks that I’ve learned along the way so that you too can “get your Swagger on.” Let’s get started…

Making Regular Expressions Simple With VerbalExpressions

Chris Berry JavaScript, Problem Solving, Tutorial Leave a Comment

Regular expressions are not the easiest thing in the world to quickly understand. Most developers only work with regular expressions when they really, really have to.

But what if there was another way?

There is and it’s called VerbalExpressions. VerbalExpressions is a collection of over two dozen repositories and libraries that use plain and simple language to describe a regular expression. In fact the motto they use is, “Regular Expressions made easy”.

VerbalExpressions is a quick and easy way to write complex regular expressions. In this blog, I will use the VerbalExpressions JavaScript implementation as my library of choice to demonstrate this great tool to you.



Quick Introduction to the Computer Vision API

Brad Kirtley .NET, Technology Snapshot, Tutorial Leave a Comment

Machine learning is a hot topic these days because the biggest tech companies are focused on taking this technology to a new level. For instance, to help develop autonomous driving cars, better interaction between you and your house with products like the Amazon Echo.

Machine learning is a core sub-area of artificial intelligence. Machine learning enables computers to self-learn without being explicitly programmed. As new data comes available, the computer has the ability to learn, grow, change, and develop itself to make better decision in the future. This technology will help reduce the workload and possible incorrect diagnoses when radiologist read films, reducing the amount of accidents on our highways caused by human error, possible reduction of inappropriate message / images / videos from bullying on social network sites.

This article will touch on one of the many Artificial Intelligence API’s that Microsoft has built for public consumption. We will specifically focus on the step-by-step process of uploading a picture, passing that picture onto the Microsoft Cognitive Services – Computer Vision API, and retrieving different attributes about that image. This is an aspect of AI technology that companies like Facebook & Google are using to try to stop bullying and other issue within social networking. Let’s get started…
