Hey Sergey, here's my post blair55.github.io/blog/paralle...

Advent of code in F# - day 02 youtu.be/AIuhrDGmuVA github.com/jovaneyck/ad... #adventofcode #fsharp

〰️ Introducing F# 10 〰️ ...improved performance and enhanced tooling to make functional programming in .NET more productive than ever. ...whether you’re building web apps, data pipelines, or cloud services. Learn more about what’s new: msft.it/63323tnbiS #dotNET #FSharp

Let the party begin! medium.com/@lanayx/the-... #fsharp #FsAdvent #oxpecker

And yet another example where #fsharp shines. Improving performance by parallelizing code. So simple and almost effortless:

Er intervjuet av Blikk om at vi i forskningssaken har mottatt en rekke godkjenningsdokumenter som viser tegn på forfalskning: - Tillatelser finnes i mange ulike versjoner med samme dato - Tillatelser er gjenbrukt - Metadata viser at dokumentasjon har blitt produsert som respons på innsynskrav.

F# 10 enhances functional programming on #dotNET with nullable reference types, optimized equality checks, faster integral ranges, and improved tooling diagnostics. It reinforces F#’s reputation as a concise, reliable, and high-performance. Learn more: msft.it/63320tr2J2#dotNET

Fable 4 and Fable 5, both got a new release to make them work with .NET 10 🎉 #fsharp #fablecompiler

A few things I have learned the last week while building an app using F#: 1. 🚨 F# won’t save you from missing pattern cases. Haskell treats non-exhaustive matches as warnings; F# treats them as a suggestion. Turn on --warnaserror+25 if you want the compiler to act like it cares.

My five-project (along with slides, video lectures, etc.) compilers course has all projects now available online free: kmicinski.com/functional-p.... Five projects have you incrementally build a compiler for a substantial language, including functions, mutation, loops, vectors, etc.

Everyone voted right? github.com/fsprojects/f... #fsharp

F# 10 makes it possible to use let! .. and! to await two tasks in parallel. This brings back some memories!

Hurray #fsharp got released! learn.microsoft.com/en-us/dotnet... Huge thanks to all the contributors! We will try and set up a stream in the coming weeks to review all the changes!

Hey #fsharp! Ionide 7.29.0 / FsAutocomplete 0.81.0 is out and brings F# 10 and .NET 10 support! Give it a try and report issues when you find them!

Dear #fsharp, we're asking again about a possible Fantomas default change: github.com/fsprojects/f... With 500+ downloads a day and only ~130 votes, we simply don’t have enough data yet. Absolute numbers matter before making such a decision.

Did you notice that the "What's new in F# 10" page is longer than the "What's new in C# 14" page? #justTrolling #dotnet #fsharp #csharp learn.microsoft.com/en-us/dotnet... learn.microsoft.com/en-us/dotnet...

What’s your favorite #fsharp F#10 feature ? Coming out today on #dotnet 10? Mine could be parallel await 💎🥰🦔 previously in some community supported packages, now part of core lib

F# Weekly #42, 2025 - Hi, Victor & .NET 10 RC2 #fsharp sergeytihon.com/2025/10/18/f...

I've heard centering anything in CSS is an unsolved problem in computer science... Hopefully once that one gets solved, the computer scientists will solve the problem of placing text input boxes in front of task bars.

I'm afraid I've just recorded a video for my Tiny Systems course on how great GOTO was in Commodore 64 BASIC :-) (Although, to be fair, I also mention some benefits of GOSUB and RETURN, which is included in bonus materials...)

I'm trying to replace my beloved but long-defunct Atom with VS Code for editing LaTeX. How do I stop copilot from telling me that I can press "Ctrl+I"? I already disabled it using "github.copilot.enable", which hides the actual suggestions, but not this useless message...

perhaps the biggest story TFPever ran was a catastrophically shoddy argument that George Floyd ackshully died of an overdose. When confronted with irrefutable evidence that the piece was simply wrong, Weiss didn’t take it down, she asked her critic, @radleybalko.bsky.social, to come on a podcast.

The article is in Norwegian… The Norwegian Church will make an official apology to the LGBTQA+ community for the harm done over the years. The press is invited on the 16th of October in London Pub (which I find funny), followed by a church service. Go church kommunikasjon.ntb.no/pressemeldin...

Just yesterday I talked to a friend about how NRK’s (Norwegian state TV) news became a complete trash, carrying water for far right. Little did I know they decided to broadcast this fascist propaganda without commentary.

I wrote a reflection on building an agentic AI into a serverless system grounded in functional principles without betraying the architecture that came before it. #fsharp is really the star of the show and we leaned very heavily into it. (I still hate gen AI) blog.bencope.land/agentic-ai-b...

#fsharp stories from the trenches 😀

I know Charlie Kirk valued debate and free speech because he blocked me for fact-checking his lies on Twitter and then put me on his organization's Professor Watchlist for writing a book he didn't like.
