I recommend to start with the previous part of the series before going ahead unless you have already read it.

Kafka as a distributed system ¶

Kafka is designed as a distributed system to achieve horizontal scalability, high availability (HA), and data redundancy. Horizontal scalability means we can keep adding more and more nodes to a cluster to handle virtually any imaginable load¹. High availability describes a system that is always operational even if some of its components fail or get disconnected. Data redundancy is employed to ensure there is no data loss or corruption.

Finding references in C# code with Roslyn and F#

Introduction ¶

The most of .NET developers use Roslyn (the .NET Compiler) everyday. But apart from compiling code it comes with a versatile APIs used for syntax highlighting, analyzers, navigation tools just to name the most typical ones. I want to show you how to use it in your own tools. This time I want a tiny tool that finds all usages of a class¹ in a solution².

Let’s code ¶

I picked F# as my language of choice for this post. The code is easily translatable to C# though. All the code from the article you can access here.

Kafka for Mere Mortals #1

Sun, 01 Oct 2017 23:31:44 +0100

This series of posts is an attempt to explain what Apache Kafka is and to show some benefits of using it side by side with a relational database in a .NET (or really any) distributed solution. I am by no means expert in any of those technologies so take all of that with a pinch of salt. I am assuming you will have a basic knowledge of relational databases and some experience in building applications.

Slack Deployment Notifications

I’ve got a simple ASP.NET Core 2 web application setup hosted in AWS. My environment is built of 3 servers (build, web, and db). I want to minimize all AWS costs so I keep the servers off most of the time. Whenever turned on they get random public IP addresses from the AWS pool. I’ve got a really simple build and deployment process which apart from the usual elements also has the following step:

Need for Blog

Sun, 10 Sep 2017 14:41:13 +0100

I’ve had a few attempts to start my own dev blog or website. However I would have always been pushed away by cumbersomeness of blogging platforms. To be fair I’ve never liked web interfaces. Needed a more dev-centric way of publishing own content. And finally I have discovered one that works for me (better later than never). It’s called static websites generation and it isn’t anything new whatsoever. Static websites are as old as the internet itself however thanks to evolution of web technologies (namely JavaScript, CSS, HTML, web browsers) it has been brought to a completely new level. The idea is to generate your web site in advance removing a need of a complex server environment (like databases or server-side processing). Obviously it has its limitations but I believe it works for blog-like websites very well.
