Our team develops a back-end system that processes messages from mobile devices. The devices collect information from complex machines and send messages to our data center. In this article I want to share our approaches to building such processing software. The ideas are quite general and can be applied to any system of the following architecture...
Our production databases were migrated from SQL Server 2012 to SQL Server 2014. Among other improvements in the latter, the new cardinality estimator was introduced. The new estimator is supposed to be smarter than the old one, of course. It takes more factors into account, and thus should give better results with some query plans. But "new" also means "less tested"...
In this post I'd like to share my experience about the first hackathon that I took part in. It was called The Green Hackfest and took place in Utrecht, the Netherlands on 10-12 October 2014. My team won a price of 1000 EURO, so read on to know what hackathon is, why you should go there, and how to score the price. And of course, pictures, pictures, pictures.
We use constructor dependency injection throughout our application. Most service classes have constructors, which accept all dependencies in form of interfaces. We also use TDD, which means we must write unit tests for every aspect of our code. So I want to discuss one specific aspect: guarding the constructor parameters from null values and testing this guard.
This post is a short summary on why do code reviews, what the steps are and what should actually be reviewed. The text was created to set some common ground for my team, which was just starting to conduct code reviews in a consistent way.
I've been exploring Aurelia javascript UI framework recently to get some experience needed for our next big project. One thing that I couldn't implement out of the box was a kind of animation.
If you have business application of any decent size, your most important code probably resides in domain logic. Try to make it as simple and readable as possible, and it will always pay you back. Today I want to discuss one aspect of writing clean domain code: units of measurement.
Recently I was playing with Aurelia SPA framework, which makes heavy use of jspm and SystemJS for modules/packaging. This package manager is new to me, and it looked a bit like magic sometimes. So when I saw a jspm course on Pluralsight, I decided to give it a try. And I did not regret: the course is great.
In this post I want to share a simple tutorial on how to deploy your single page application into the Azure cloud. I have a Single Page Application (SPA) done with HTML/JavaScript in a separate local Git repository. I alsp have a ASP.NET 4.6 Web API service which serves the data for SPA in another local Git repository. Now I want to deploy both to the Azure cloud, and make it easy to deploy changes in the future.
When I model the business domain with C#, the resulting data structures tend to contain a lot of boilerplate code. It's repeated from class to class and it gets more difficult to see the essence of the model behind the repetitive cruft. In this article I show off one trick to reduce this boilerplate code with Fody library.
