Learn how you can rapidly access, manipulate and visualise data in a type-safe manner on Mac, Windows or Linux using completely free tools and libraries using a combination of F#, .NET Core and Visual Studio Code. Rapid Data Analysis with F# - Part 1 - Scripts and Data Capture

Have a recap of Isaac's showcase of rapid data analysis with F#. Although quite a dated video, it still holds true to F#'s power in being able to prototype quickly to get the result you're after... but most importantly, in a fun way!

The new `tryParse` fn in FSharp.SystemCommandLine makes it easy to parse any input type using the F# Result type for built-in validation. Perfect for parsing discriminated unions, or... anything. #fsharp

.NET Script APIs 🌞 with F# and dotnet fsi 🌴

Btw #csharp #dotnet in 2023 in #fsharp was running aspnetcore in technically 1 file and some imports, make this possible for .fs also would be great to also import sdks 🥰🦔 talking about “dotnet run file.fs|cs” > jkone27-3876.medium.com/net-script-a...

R Ok, I need to write a quick F# script that takes a clustal aln formatted file with two proteins called mouse and human. | have a list of mutation in the mouse protein and want to find the matching human coordinates © map_coords.fsx1

I've been having a lot of fun writing an @avaloniaui.net app in #fsharp

Wrapping C and C++ A design that builds type and memory safety into legacy code without rewrites

💡 One of the benefits of the Fidelity framework design for #clang and #cpp users are memory and type safe wrappers for APIs without rewriting code. With #fsharp idioms and BAREWire memory mapping support, we can create "shadow APIs" that make drop-in replacements possible. speakez.ai/blog/wrappin...
