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!

I still think this is the best way of doing composable data visualizations. See the paper:

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. 😁

It's way more complicated than just that. * Covid did significant damage to all meetups - many did not restart, including F# meetups * Some people lost interest in fighting for F#, because some won (using it daily) * Yup, some people left, but some came (Amplifying F#) Always niche, but still cool!
