Zompist Bboard Again

Once again, I had a fairly productive day so far.

My cousin is sharing his mental health story on social media for Men’s Mental Health Month, which I have just recently learnt is June. I am proud, happy, and thrilled to see him speaking out, common sentiment be damned.

That's good!

I got my screenshot tool for the graphical PicoCalc terminal emulator for zeptoforth working.



(Note that this is of my emulated PicoCalc, so the screen is 320x240 rather than 320x320.)

What's the importance of January 1st, 1980, in computing?

It's when dating begins in the FAT32 filesystem. I hadn't configured my RP2350 on my Pimoroni Pico Plus 2's Always-On Timer so it defaulted to 0, which for my purposes I am treating as midnight January 1st, 1970, but FAT32 does not handle dates that early so I am using the year 1980 instead.

Thank you!

I created a 'Matrix' demo for zeptoforth on the PicoCalc, and here is a screenshot of it on my emulated PicoCalc:

This is a First World happy thing, but I received and assembled my PicoCalc yesterday -- and had to pay zero extra on it -- and the only real hitches were some "BIOS" interaction code that I wrote that I had never gotten the chance to really debug previous not working properly (which I quickly fixed).

I implemented a Mandelbrot set on my PicoCalc, and here it is:



Note that this uses hardware single-precision floating point, so requires an RP2350 (e.g. a Raspberry Pi Pico 2).

Here is another view of the Mandelbrot set, acquired with:

The second one looks like a natural coastline.

I have now implemented a Sierpinski triangle with turtle graphics:

All you need to do now is two-dimensional projections of four-dimensional polychorons, and I'll be in awe of you forever Oh, and implement a fully-working port of brassica.

LOL.

It’s not that hard! All Travis needs to do is to write a full-featured WASM interpreter, and then he can run Brassica!

Yeah, a program written in Haskell of all things will fit in the 520K of SRAM on an RP2350 - lol.

And now, a Barnsley fern on the PicoCalc!

Well, it might be a teensy bit slow…

(But the fern is lovely! I’ve long had a soft spot for IFSs.)

And now some generations after the creation of an R-pentomino in Conway's Game of Life on the PicoCalc:



The source code is https://github.com/tabemann/zeptoforth/ ... lc_life.fs here, with some helper code at https://github.com/tabemann/zeptoforth/ ... fe_demo.fs.

After loading the two source files, in that order, execute:
To create an r-pentomino at (160, 160) in it execute:
Then, to run the Life world, execute:
This can be exited by pressing a key on the console.
