Vogon Poetry Review – Azure Service Fabric
On January 24th, Doug spoke at our Vogon Poetry Reading about Azure Service Fabric. This technology is something that we are very bullish on as the future of hosting. Why do we like “the Fabric”? The programming model closer mimics how we currently write software. Reliability / scalability is basically baked into the fabric. Azure…

Getting Started with Ionic, Part 2
In my first Ionic blog post, we just got started creating a simple app using Ionic. In this post, we are going to create a simple application that is a basic contact manager. To speed this along, we are going to build off of what we started in part 1. The first change is ironically…

Getting Started with Ionic, Part 1
There are many strategies to building mobile applications. Some people prefer to go the 100% native route, writing their applications in Swift / Java. Others like to use Xamarin and write one application in C#. There are yet still some that just write a single website that works well in mobile. In this article, we…

SOLID, Part 5: Dependency Inversion Principle
In this five-part series, I’m covering each design principle laid out in SOLID. In this final post, I am covering the dependency inversion principle. The “D” in SOLID is a pretty well understood principle. It is supported by a variety of platforms, including Angular. The code below shows how it is implemented using Angular. The…

SOLID, Part 4: Interface Segregation Principle
In this five-part series, I’m covering each design principle laid out in SOLID. In this post, I am covering the Interface segregation principle. The “I” in SOLID is a principle that is easy to skip over. Everyone will always remember the “S”, because it is first. The “L” is easy to remember because it is…

SOLID, Part 3: Liskov Substitution Principle
In this five-part series, I’m covering each design principle laid out in SOLID. In this post, I am covering the Liskov substitution principle. Now is when things get interesting: program to an interface that can be implemented by many services. The Liskov substitution principle (LSP), created by Barbara Liskov, says we can substitute one service…

SOLID, Part 2: Open / Closed Principle
In this five-part series, I’m covering each design principle laid out in SOLID. In this post, I am covering the Open / Closed principle. The Open / Closed principle is hardest to argue for. In our SOA (service-oriented architecture) world, we try to avoid using inheritance as a method to change behaviors. We would tend…

SOLID, Part 1: Single Responsibility Principle
SOLID is an acronym created by Robert Martin (Uncle Bob) to describe five principles we should follow to make software designs more understandable, flexible, and maintainable. In general, these are very good guidance. While I don’t think the acronym is perfect and I don’t really focus on the open / closed principle, I do think…

A Website Without Servers – Using Azure Functions: Part 8
Azure Functions fit a nice slot: for times when you don’t want to deploy much but want a little bit of logic in the cloud. There’s another feature that really gives Azure Functions some legs: you can proxy request to blob storage. This might not seem like a big deal, but it is a game…

The Mechanical Turk (The Love Test for Entrepreneurs)
For the last couple of years, I have spent a significant amount of time talking to innovators both independent (entrepreneurs) and inside of organizations (intrapreneurs?). The conversations generally focus on a variation of these familiar themes: Uber for … Ebay for … Facebook for … Computer vision to … Artificial Intelligence / Machine Learning to…
