After a loooong vacation, I published a new version of #Feliz #DaisyUI library. Big kudos to Oleksiy Slyshyk, who did all the work (I just pushed the button 😁)

The wait is over! Fable 5 Release Candidate is officially here.
After a year of hard work from the community, we're bringing you:
✨ .NET 10 & F# 10 support
🐍 A massive Python update (now powered by a Rust core & PyPI!)
🌐 Cleaner JS/TS Pojo bindings

Using GitHub Agentic Workflows "Repo Assist" automated repo assistant, I was able to
1. Clear all the lingering technical debt off the community library FSharp.Control.AsyncSeq today
2. Release a new version 4.0.0 with a major compat feature
github.com/fsprojects/F...

F# folk - I'm having some success using GitHub Agentic Workflows to automate some backlog maintenance work in some older F# community repos.
FSharp.Data: github.com/fsprojects/F...
FSharp.Control.AsyncSeq: github.com/fsprojects/F...
It's helping me re-engage with the repos and clean things up.
After some *checks notes* umm.. 6 years, I released a new version of my composable data visualization library, adding support for images! compostjs.github.io/compost/demo...
I still think this is the best way of doing composable data visualizations. See the paper: www.cambridge.org/core/journal...
Adding a video streaming feature to my www.triple19.com application seems to be fun. The more features, the more stuff to talk about at some FP conference? 🤔
A new web page for my book! tomasp.net/cultures/
It has all the links you may need to get the open access PDF, buy a hardcopy or an ebook as well as some older talks & slides.
If you run a podcast, conference or a user group, I'm always hapy to join & talk about something from the book!
Sure. I combine Claude Code for bigger features and Copilot in IDE for code updates. Landing page was done by @claudecode.bsky.social with some fine-tuning 🙏
Aaaaand one more thing: F# union types are still the best thing ever. ❤️ I cannot imagine handling game state transitions in any other way, it's just perfect. And btw... I did "an AI stuff" in it - you can just say out loud your throws and it will do the math for you.
I did a new thing with #fsharp on backend and pinch🤏 of #typescript on frontend. It's called Triple19, running on www.triple19.com and it's all about my new-ish hobby - Darts. It's quite complex and I'll do tech talk about it one day, but now if you would give it a shot, would ya? #darts
I wonder... would there be any interest in some F# event / (un)conference in 2026?
I always wanted to do something similar to F# Creators Workshop (which @dsyme.bsky.social organised years ago in Cambridge) or Elm Camp (which has been for last couple of years)

Many thanks to everyone that made this release possible! 😘
Looking forward to coming to this amazing conference exploring the gaps in computer science research!
C# and F# Interop (2026 edition)
How to easily start with F# in your existing C# codebase.

#dotnet #csharp #fsharp #Interop
A beautiful F# library for building AI agents on .NET:
• Quotation-based tool discovery
• Pipeline-style agent composition
• Computation expressions for workflows
• Railway-oriented error handling
F# deserves a place in the agent era — and this is my contribution.

Common terms in F# that I hadn't heard before coding with it:
* Computation expressions
* Railway-oriented programming
* Partial application
* Currying
* Monads
* Discriminated Unions
* Exhaustive pattern matching

One thing that always surprises me is the .NET community's obsession with mappings and mapper libraries. I DO get the temptation to have a one-liner instead of 6 lines, but I genuinely believe that if this is a problem in your code, you either have too many layers or messed up your abstractions. 😁
okay this is extremely fucking funny
