In this blog post we'll cover how systems form clusters, what clusters actually are and what are their responsibilities. We'll also present different protocols responsible to serve the needs of the clusters with a various tradeoffs associated with them. To…
Dealing with complex dependency injection in F#
Today, we're going to cover different ways of encapsulating capabilities and supplying them between functions using functional programming techniques which can be realized in F#. Managing code dependencies in object oriented languages in 2020 is pretty much one sided problem:…
State-based CRDTs: Maps
In this blog post, we'll cover the idea of CRDT maps, and how we could create them and utilize them in common scenarios. A prerequisite for this talk is some general knowledge of CRDTs, especially observed-remove sets, which were already…
Building custom fibers library in F#
Over the course of last few months on this blog post, I've been sharing about internals and how-to of different concurrency patters. We discussed how to implement our own actors and specific affinity-based thread pool. Today we'll focus of the…
Thread safety with affine thread pools
In the previous blog post I've written about building a thread-safe state access by using actor programming model (as opposed to common practices requiring synchronization barriers with locks) without compromising performance coming with running our programs on multi-CPU machines. As…
Build your own actors
What the actor model is all about? While actors are very broad term, in Software Engineering we comonly refer to them when speaking about languages (like Erlang or Pony) or frameworks (like Akka or Orleans). Here however we'll try to…
State-based CRDTs: Bounded Counter
Originally, I didn't want to make a separate blog post about design behind bounded counters, but since beside original paper and a very few implementation living in the wild, this CRDT is widely unknown, I've decided to give it a…
Optimizing state-based CRDTs (part 2)
In this blog post we'll continue exploring the ideas behind optimizing state-based CRDTs. This is a third post from the series. If you haven't read them before this article and don't feel familiar with CRDTs, I advise you to do…
