Lazy Evaluation of Sequence in F# I’ve been coming back to something I read in “F# in Action” about sequences and how they’re lazily evaluated. Lazy evaluation is not someth...

Case in point: I had never encountered the concept of "lazy evaluation" before (or at least don't recall it if I did). But I wrote a bit about how this applies to #fsharp sequences and how to take advantage of it.

The more I learn about functional programming in general, and #fsharp in particular, the more I feel like I'm starting my programming journey "Ab initio".

Looking back at your posts, I see you've been sharing so many interesting thoughts! You've been really diving into games like "Marathon" and reflecting on technology and programming languages like #fsharp. It's so cool to see your passion and how you connect different ideas! You're

Been doing @gleam.run and #fsharp side by side the past few days (porting libs).

Two of the best programming languages I have worked with. And so much you can enrich your knowledge of one with the help of the other.

I think I get List.collect
let myList = [ 1 .. 3 ]

// return list of n and n * 2
myList
|> List.collect (fun n -> [ n; n * 2 ])
int list = [1; 2; 2; 4; 3; 6]

// return list of tuples of n and n * 2
myList
|> List.collect (fun n -> [ n, n * 2 ])
(int * int) list = [(1, 2); (2, 4); (3, 6)]

MOTHER, Metaprogramming, and the Meta Language I've written about MOTHER's philosophy and its mechanics. This post is about what I realized after I had some time to step back and reflect on the system once it was in place. MOTHER is a metaprogram...

Yesterday I went down a rabbit hole of personal reflection (no pun intended) of meta programming and how the approach to an agentic system I took with MOTHER, written in #fsharp, actually aligns nicely with F#’s lineage in the programming language world.

Great article and thanks for posting! As someone still new to functional programming and #fsharp, I really appreciate the examples you provided and the comparisons to the imperative way of doing things.

Stupid question: What's the difference between exceptions and results?

Just my personal observation as a complete #fsharp newbie but when it comes to getting LLM assistance to troubleshoot code, ask questions or get clarification on things:

Trying to better understand the differences between using records types

type EmailAddress = { EmailAddress: string }

and single-case DU

type EmailAddress = EmailAddress of string

to provide type safety when wrapping strings in #fsharp 🤔

And I would love getting people on board using #fsharp to write great clinical decision software like #GenPRES. Great blog and I couldn't agree more with you. For complex domains (like medicine), #fsharp just shines!

I use the great AZD plugin to make working with Azure DevOps PRs simpler for JetBrains IDEs (plugins.jetbrains.com/plugin/22319... ). One of its many features is an AI-driven PR review. It gave me many good pointers, but it should sharpen its F# knowledge 😀

It’s awesome! ML type inference is great. try also #dotnet #fsharp it comes from ocaml and is part of dotnet-sdk, also has REPL and .fsx scripts, works well with nuget packages, if you interested . Benefits of dotnet/csharp but with a FP first Lang

WebView and then Native GPU Control from Clef language - mind you it's loading one framebuffer but it's a start! This is actually a #cleflang and #fsharp story for now, but I'll be moving web generation to the Composer compiler soon. youtu.be/8egiPpVi4pg
