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…

Whatever Bill Has…The Results
Last week we launched the “Whatever Bill Has” app, which I built as a demonstration of Azure Functions. This app is basically Build-A-Bear, but with Bill Udell. Users had eight possible options: four shirts and two pants. Bill was gracious enough to provide us with some great shirt and pants options. He also chose a…

Whatever Bill Has
Those of us who are engineers know we aren’t looked up to for our fashion sense. We tend to be t-shirt and jeans people, or sometimes t-shirt and sweatpants people. Now this isn’t a sign of anything wrong, but I often feel engineers are just focusing a little too much on the function. I think…

Don’t Design the Database First
Build bottom-up right? Start with the database schema, then models, then the UI, then ship it, right? Well, I think the majority of new projects would benefit from not focusing on the database until much later. Why not focus on the database from the start? Managing database changes in the early phases of a project…

A Website Without Servers – Using Azure Functions: Part 7, Angular Service
If you haven’t been following along in this series, we are building an “Engineer Fashion App” using Azure Functions. I recommend looking back at Parts 1, 2, 3, 4, 5, and 6 to see what we’ve done so far. Let’s assume we have an Azure Function that returns some JSON for our wardrobe and that…

A Website Without Servers – Using Azure Functions: Part 5, Pulling Wardrobe Data
Previously on Using Azure Functions, we set up a very simple Angular website. This week, we are going to set up an Azure Function that pulls some wardrobe data from an Azure Cosmos database. Why not just build the wardrobe into the app? Well I’m hoping to update the wardrobe by season, so having to…

A Website Without Servers – Using Azure Functions: Part 4, Angular Site
In part 1, we set up some basic infrastructure for our engineer fashion app. In part 2 and part 3 we configured some source control so we can work like sane people. Now we are going to stand up a very basic Angular site. Angular, do you mean Angular 1 or Angular 2? Well I mean…
