AI workflows in #fsharp! What #vide's README promised years ago: state-aware functions, now async, effectful and persistent - with a UI on top. - let! is a step, if is a branch, let is just a value - a run's state IS that nested let! tree - an AI can write, watch and steer them

There's now a wonderful VSCode extension for #fshttp called "FsHttp.Studio": Run http queries with 1 click and get responses rendered beautifully in the editor. Thank you @tw0po1nt for putting effort and passion making #fsharp even better! github.com/tw0po1nt/FsHttp.Studio cc @sergeytihon.com

Who needs benchmarks when instruction following can be examined in such a funny way (running a local LLM in #hermesagent). In a session with over 150 messages, not a single STOPP was missed. So it's true: #ornith is not the #KingOfRap, not the #KingOfPop, but the #KingOfSTOPP :D

Model-Shootout: I built a custom AI agent using #fsharp that turns #GitHub Issues into Pixograms for our #pxlclock. Same idea run with Frontier models (#claude) and self-hosted like #Qwen and #gpt-oss. Results: schlenkr.github.io/pxl-clock/ (buy a clock if you like it: www.pxlclock.com/?ref=RONALD)

How do you find my new TypeFighter logo? A tiny experimental language I just rebooted. Structural records, set-theoretic unions, almost no annotations. The goal: keep "could be this, or this" alive as long as possible. schlenkr.github.io/TypeFighter/ #typeinference #fsharp

Hey @ursenzler.bsky.social + @nojaf.com: if you have some time, check out SchlenkR/pxl-clock on GH. You can now create "pixograms" just by opening a GitHub Issue and describing what you want. AI does the rest, you get a GIF preview, iterate via comments...

Grab the #pxlclock VS Code extension ("PXL Clock), code your own pixogram in #csharp, and ping me here: I'll record it on the real hardware and post the video. Who makes the coolest one? VS Code: marketplace.visualstudio.com/items?itemName=pxlclock.pxl-clock #pxlclock #csharp #fsharp

From sourcecode to step-by-step tutorial: I wanted to advertise the #pxlclock using programming tutorials. So I built this: - AI breaks the #csharp code into steps; thanks @ursenzler.bsky.social - Renders animations - Writes tutorial - Remotion makes the reel Want a video about how I did that?

Vibe-coded a macOS Push-to-Talk app. Whisper running locally, zero cloud dependency. Added a waveform animation that looks cool though (IMO). github.com/SchlenkR/push-to-talk Have fun!

The age of programming languages is over. I built one anyway. Type inference. No annotations. Errors caught before they happen. The theory is from the 70s - compilers were doing "inference" long before #ai :) youtu.be/fSRTVrjvo70 #typeinference #compilers #fsharp #csharp #ocaml #rust

Happy Friday :) Program your own Pixogram — in VS Code. PXL Clock #vscode extension is out: • Built-in simulator, zero setup • Live preview + hot reload • Publish to your clock in one click Write C#, see pixels. No device needed. github.com/SchlenkR/pxl-clock #pxlclock #csharp

New PXL Clock simulator: • Looks like the real device now • Clean UI • Program in C# • Stream to your real clock • Browser-based, no hardware needed Testing for upcoming PXL tutorials with AI! @ursenzler.bsky.social I ported all your ClockFaces to #csharp - Ok? github.com/SchlenkR/pxl-clock

My recording "studio" is my kitchen. No regrets — it's the coziest room in the house. Setting things up to film #csharp coding tutorials for the #pxlclock. Write code, run it on the simulator, watch it glow on the real thing. First tutorials dropping soon. Stay tuned!

Built a small tool for my social media workflow: Write posts as markdown in VS Code, use Claude Code to draft them, then preview everything in a local web dashboard before publishing. No database, no CMS. Just markdown files, ~300 lines of #fsharp and some JS. github.com/SchlenkR/post-dashboard

Wanna help us sell the PXL Clock? You get paid for it :) Sign up, get your link, earn €25 for every clock sold. No catches. Join here: pxlclock.goaffpro.com/create-account #pxlclock #dotnet #csharp #indiemaker

Almost ready to ship: deploy C# apps directly to your PXL Clock. Write code, hit deploy, it compiles on the device. Looks familiar? :) Try the free simulator + examples: github.com/SchlenkR/pxl-clock 25% off with code RONALD: pxlclock.com/?ref=RONALD #csharp #pxlclock #fsharp #pixelart

Relaunching LocSta - a stateful stream processing library for #. No classes, no boilerplate. `stream` CEs with automatic state management. ~47 blocks: oscillators, filters, ADSR, EMA, edge detection… Interactive demo site (via Fable). github.com/fsprojects/LocSta #fsharp #dotnet #dsp #opensource

Today I reworked the appearance of the #pxlclock app. The device takes screenshots of a running clock face and uses it as image to show to the user. Now we can see all the beautiful work of @ursenzler.bsky.social in a single list without imagination :)

While crafting the #csharp API for #pxlclock, I asked my code monkey to add some static scenes for all the API we added. Look what it made - without further specification :)

That's amazing: Someone created something like an "analogue #pxlclock " :) Here: dodocraft.com Cool!

When I tell that #pxlclock is hand-made, this means: Man, it's hand-made! I swear - for real ;) You see Sefa in Action - life and in color, soldering the 2 boards for the clock. Thank god I'm a programmer... get your PXL Clock: pxlclock.com

🌈 After 2 years of serious side-project hustle, we’ve built a limited batch of 100 PXL Clocks - premium programmable clock for developers and design lovers. Use code "fsharp" for a 50€ discount and bring light into your workspace. 👉 pxlclock.com #fsharp #pxlclock #csharp #pixelart

A programmable device for #csharp and #fsharp hobbyists? A beautiful hand-crafted piece of furniture? Or both? Order your #pxlclock now (1st batch limited to 100 units): www.pxlclock.com

#pxlclock is finally here 🎉 Hand-built and crafted, with 576 glowing 3D pixels. Only 100 units available right now - made with care, not mass-produced. 👉 www.pxlclock.com PS: If you enjoy my #fsharp open-source work: this is a beautiful way to support it ❤️

576 pixels Pre order ;) #fsharp

Instead of heavy code generators, I now: - write a step-by-step spec in code - run a command manually - repeat when needed ✅ keeps the benefits of metaprogramming ✅ minimal time & cost ✅ good enough for #pxlclock moving from #fsharp → #csharp Sometimes simple wins.

Sometimes stepping back reveals small flaws & inconsistencies we got used to. Example: in #csharp, values use `Type id`, but type params use `T : constraint` Historical reasons? If starting fresh, I’d go ML-style - #fsharp shows how inspiring that can be. #dotnet

🤓 Type puzzle: What are the types of a, b, and combine in this snippet? No syntax, no rules — just inference & imagination. No right or wrong - interpret! 👉 Your guess? #typefighter #trulla #csharp #typescript #java #fsharp
