In FSAC repo, I'm getting great PRs closing 7 years old issue… from AI.AI slope? It's polished PR, adding code fix and set of tests for it. I wish I was getting such "slope" from #fsharp community for all those years… github.com/ionide/FsAut…

Might not be a huge audience here, but I wanted to announce that. FSharp.Data.Npgsql is now part of fsprojects, thanks to @dsyme for the nudge. This should make maintenance easier.. It's a #typeprovider wrapper in #fsharp for #postgres that allows you to just point your code at a database and […]

11 years ago I’ve made first commit on the project that would later be known as Ionide. A lot has changed over all those years, but one thing remains – the biggest value of the project has been meeting awesome people from F# community, many of whom I’m proud to call friends.#fsharp

F# folk, with @nojaf.com we've added support for generating llms.txt to the fsdocs tool that's widely used by the F# community.We'll release it soon but if you have a chance to take it for a spin before please do.github.com/fsprojects/F…#fsharp

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.

Well, it's in the can! 🤖 #FPGA end-to-end compilation with bit width inference confirmed with #cleflang, including AMD/Xilinx bootstrapping the flash process in the back end #fsharp #ocaml #haskell #rust #dotnet

I need to double (and tripple) check this but it seems like Giraffe on Beam is faster than .NET. Is it too good to be true? 🙈 At least the Python perf looks to be true 😆 #fsharp #fablecompiler

Next week @dsyme.bsky.social shows how agentic workflows can continuously improve #fsharp libraries.amplifyingfsharp.io/sessions/202…

Perhaps not too impressive for now but this shows Giraffe (F#) running on the BEAM (Erlang Runtime) using Fable (WIP) #fablecompiler #fsharp

An ode to "slowly" handcrafted codewww.planetgeek.ch/2026/02/02/a… When I open my social media feeds, it's obvious: the age of writing code with our fingers is ending. LLMs can write code much faster.But was it ever about the speed of code creation? I think not.#LLMs #agents #fsharp

I did a new thing with #fsharp on backend and pinch🤏 of #typescript on frontend. It's called Triple19, running on http://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
