For a long time, I wanted to implement a Racket language module with a non-lispy surface syntax.

Recently, I stumbled upon this paper Synthesizing Object-Oriented and Functional Design to Promote Re-Use.

Lately, I've been exploring various examples from Sutton and Barto's "Reinforcement Learning: An Introduction" book using C# and I already shared a few of them on this blog: Tic-tac-toe reinforcement learning with C# Ten armed testbed for the Bandit probl…

A few weeks back I became aware of an attempt to create a technology agnostic standard to send and receive webhooks securely.

After thinking about it for some time I decided to add a comment system to the blog.

I had the Ray Tracing in One Weekend book in my todo list for a long time and I had finally the time to go through it.

Recently I tried to code the 10 armed testbed example from chapter 2 of Sutton and Barto Reinforcement Learning: an introduction book.

I'm continuing my attempt to reproduce examples from Reinforcement Learning: An Introduction book using C#.

A few years ago I needed to troubleshoot some imports based on csv files and I had one big issue, depending on the language the user was using on Windows, Excel would export csv files with different separators.

The asynchronous request reply pattern is useful in cases where an application has a client application running in a browser where the user starts an operation and is waiting for an immediate feedback and possibly a success notification.

A couple of weeks ago I wanted to take a look at reinforcement learning and possibly work on a very simple sample in C#.

info Since writing this, LLVMSharp had a new stable v20 release.

Given my previous attempt of having a basic scaffolding for creating a new racket language, I thought it was worth a shot at implementing Lox from the Crafting interpreters book as a Racket language module.

This is an update on this post, on wireplumber v0.5 lua configuration files are not supported anymore.

warning On 2025-08-02 I updated the repo corresponding to this post to use updated versions of Kubernetes, Cilium and Gateway API.

warning The lua configuration files are valid only for wireplumber v<0.5.

I updated my TreeSitter.Bindings packages to support additional languages.

info The post and the repository has been updated on 07-05-2025 to use latest versions of sops, kubectl, azure apis.

I want to leverage my visitor pattern source generator to implement a simple minimal api.

In a previous experiment I made I used the LLVMSharp library and I was quite curious on how the bindings are made.
