Lightweight observer chains

June 13, 2025

Previously I wrote about another approach making properties observable for reactive programming in .NET using the Kinetic project. This time I would like to talk about a non-less interesting feature there, boxing an observer chain into a single-state machine.

Weakly and strongly typed values in .NET

May 28, 2024

Recently I read an interesting article by João Antunes covering how different type of .NET collections handle strongly and weakly typed keys, but it lacks a very important part, an analysis of why some results are almost identical in some cases and not in others. So, let’s dive in and find answers to these questions.

It's all about properties

February 16, 2024

A few years ago I was working in the entertainment industry and participated in the creation of a brand-new graphical engine and its editor with a primary focus on cinematics. As one might expect the core was made using C++, but for the editor Avalonia UI was chosen as an easy-to-use cross-platform UI framework. Sure, it wasn’t without the MVVM approach with the support of Reactive UI. All of that worked well, but only in the beginning while the editor wasn’t very complex and wasn’t killing the performance by eating a lot of RAM and consuming too much time on event handling. One might say that the toolset was completely wrong and we should have used Y instead of X, but the story isn’t about that. It’s about the investigation being made and an attempt to solve the performance issue.
