If you’re at all interested in segmented displays Posy’s YouTube video about them is pure gold: https://youtu.be/RTB5XhjbgZA

This rare 22-segment display is the most interesting I've seen so far. It can display the full 7-bit ASCII range including special characters: https://www.youtube.com/watch?v=D2cyZoCat_U

For those who haven’t seen it before, Jones Forth is a wonderful implementation written in literate programming style.

It’s well worth reading through, even if you don’t know any assembly.

Here’s a ggplot2 example: https://webr.sh/#code=eJxtkLFOwzAQhsWapzh5ckSUpEgsSBkY2RAVrN...

There’s a simplified example here: https://github.com/r-wasm/webr/tree/main/src/examples/eval

I like how the rules to the right of the headings react to the page width and how many lines are used.

WebAssembly is generally most useful when you want to write high performance web applications using languages like C, C++ or Rust.

WebAssembly sits in the background quietly powering the web-based versions of products like Adobe Photoshop, AutoCAD, Figma, Canva, and likely others. By using Wasm components combined with other browser technologies such as HTML canvas and webGL, app performance and responsiveness can be improved.

WebAssembly also powers the Pyodide and webR projects, enabling Python and R code to run in a browser without a supporting computational server. Where I’ve seen this used most effectively so far is in teaching materials, particularly for teaching data science, where interactive R and Python examples can be embedded directly into teaching materials without the educator having to worry about the time or expense to deploy a powerful backend service to evaluate learner’s code.

I’ll definitely be trying out more of LFortran in the future.

For this post I really wanted to go deeper into the approach we’ve taken with flang, but I can see that LFortran is also a very strong choice here for running Fortran on Wasm.

Thanks. Please report all bugs that you find. I talked to my collaborators, we'll try to get some simple demo of Fortran->LLVM->WASM working soon, we need to figure out the runtime library issue (like you did), hook it into the driver, etc. I was in fact thinking about exactly this just last week, to easily distribute my simple computational codes online via static pages.

I think exactly the approach that you took with Flang should work with LFortran also.

Thanks! There’s a series of books I really like, The Theoretical Minimum[1], that also takes that kind of approach but for teaching physics.

Yes, I also like The Theoretical Minimum. Ha, I didn't realize there is more than one book! I think I only have the classical mechanics book. Need to buy the other ones.

I tried to organize many physics subjects in a similar manner, with many worked out examples (minimal, but non-trivial/complete):
