Static Types Without the Hassle: Type Inference Demystified YouTube video by The Pure State

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 :)

#typeinference #compilers #fsharp #csharp #ocaml #rust

...

Also: HTML tags from my README (images, links) end up as raw HTML in llms-full.txt instead of markdown. Might be worth a follow-up issue (... for fsharp formatting?)

Have a nice weekend!

Just tried it with FsHttp; Works out of the box.

fsdocs-tool 21.0.0 already includes it (default on via FsDocsGenerateLlmsTxt MSBuild prop)?

One thing: 21.0.0 now targets net10.0, so global.json needs SDK 10. Minor finding; FsHttp was pinned to 8).

...

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

Pxl-Clock | LED Pixeluhr Die PXL-Clock ist eine minimalistische LED-Pixeluhr – stilvoll, handgemacht & limitiert. Ein Designobjekt für alle, die Licht & Zeit neu denken.

P.S.: You can buy a PXL Clock and get 25€ discount using my code:

www.pxlclock.com/?ref=RONALD

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.

Almost ready to ship: deploy C# apps directly to your PXL Clock. Write code, hit deploy, it compiles on the device. Looks familiar? :)

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).

#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 :)

Type Inference: Bridging the Gap Between Safety and Simplicity YouTube video by The Pure State

Let's build a Programming Language - together!

The goal? Combine the developer experience of Python with the safety of TypeScript.

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 :)

Good info - haven't thought about that (I usually trust myself :D ) - ok. Wer need to update the app for that...

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

Great! Urs, if you don't mind: Could you use Chrome and check our pxlclock.com/setup, enter your Wifi, click connect and then: See if your clock appears in the list of devices? Then, you can cancel. Thanks ;)

Yes, this is a wonderful, almost hypnotic clock face :)

BTW, the app is officially available, and the latest clock SW version is 2025-11-09_16.08.11

Does your clock still pull updates if I may ask?

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.

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.

How comes such a feeling?

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

I guess many C# focused developers understand Func<int, int[], int[]> very well - and that's it!

or

delegate int combine(int a, int[] b)

(although the names are just documentation, and not part of teh type's identity.)
