Building Microservices with Azure Kubernetes Service and Azure DevOps - Part 3

by bill-s, 2019-03-14T06:21:38.429Z

One of the major points of doing microservices and containers is avoiding the “it works on my machine. While containers are a vehicle for achieving this, we also need a vehicle for carrying the container from the developer workstation to other machines. In this guide that vehicle is Azure DevOps, the artist formerly known as Visual Studio Team Services (VSTS).

Easily add real-time web functionality to applications with Azure SignalR Service

by bill-s, 2019-03-14T06:22:22.051Z

Hi, folks. Today I wanted to chat with you about real-time web functionality. Normally when we think of the web, we think of a mostly passive experience. When you bring up your mail web client and leave it for a while, your mail gets stale. You won’t get your recent emails until you refresh the page, or, if you’re lucky, your client has a timer that automatically refreshes the page for you. But it doesn’t have to be this way. SignalR is a technology that can push new emails to you as soon as they arrive. Using SignalR, you can even have a real-time, two-way conversation with someone over the web. And with Azure SignalR Service">, you get a fully managed service that helps you build real-time experiences such as chat, stock tickers, live whiteboard, and more.

Is C# a low-level language?

by bill-s, 2019-03-14T06:30:45.732Z

I’m a massive fan of everything Fabien Sanglard does, I love his blog and I’ve read both his books cover-to-cover (for more info on his books, check out the recent Hansleminutes podcast). Recently he wrote an excellent post where he deciphered a postcard sized raytracer, un-packing the obfuscated code and providing a fantastic explanation of the maths involved. I really recommend you take the time to read it! But it got me thinking, would it be possible to port that C++ code to C#?

My integration testing challenges this week

by bill-s, 2019-03-14T06:26:55.255Z

This was meant to be a short post, or at least an easy to write post on my part, but it spilled out from integration testing and into some Storyteller mechanics, semi-advanced xUnit.Net usage, ASP.Net Core logging integration, and even a tepid defense of compositional architectures wrapped around an IoC container.

Stop Wasting Connections, Use HTTP Keep-Alive

by bill-s, 2019-03-14T06:25:53.398Z

With the proliferation of third-party APIs and microservice architectures, modern web servers can make as many outgoing HTTP requests as the number of incoming HTTP requests they serve. A typical web application can interact with third-party APIs to handle payment processing, send email, track analytics, dispatch text messages, verify mailing addresses, or even deliver physical mail. A server can also rely on internal APIs to fetch account information, start asynchronous processes, or perform complex searches. Programs that initiate a high volume of outgoing HTTP requests must minimize the overhead of each in order to remain performant and optimize resource utilization.

Why isn't my session state working in ASP.NET Core? Session state, GDPR, and non-essential cookies

by bill-s, 2019-03-14T06:20:51.741Z

In this post I describe a problem that I've been asked about several times related to session state. The scenario goes something like this: Scaffold a new ASP.NET Core application Set a string in session state for a user, e.g. HttpContext.Session.SetString("theme", "Dark"); On the next request, try to load the value from session using HttpContext.Session.GetString("theme"); but get back null! "Gah, this stupid framework doesn't work"
