I'm really happy with current state of FScript: - F#/ML-style scripting focused on safe embedding: strong type inference, explicit host extensibility, and sandboxed execution. - Hindley–Milner inference with optional parameter annotations. github.com/MagnusOpera/...

@antropic.bsky.social please fix the app. Clicking a chat (and practically any other button) is super unresponsive and mostly does nothing. This is not a new issue - I've had this on multiple devices for a week now. Claude 1.1.2321 (495628) 2026-02-06T22:01:17.000Z

While the Russian Useful Idiot in the White House is busy claiming bullshit wartime authority to further his efforts destructing Democracy, just a reminder that everything he has said is a lie & everything that he says going forward will be a lie. As for his enablers, screw them.

I actually really like that #csharp allows records to inherit from another record. #fsharp does not allow that, and it feels like an artificial limitation. I'm usually not a fan of inheritance, but in this case it's just soo convenient. #dotnet

If you publish a package to #Nuget and include a link to github I expect the source code for that package to be in that repository.
