@ryrobes "practical tools for practical problems" sounds like a pretty succint and useful manifesto to me ;)

[adam-james @RustyVermeer]

@ianthehenry Yea, I guess it’s a little bit of a risk to see what happens. Personally I like the idea of “nature taking its course” with time and the natural patina. But I doubt you can make a wrong choice here ;)

[adam-james @RustyVermeer]

@ianthehenry It’s really beautiful!
I wonder if the bronze and brass will tarnish to different colours over time?

[adam-james @RustyVermeer]

Patterning things on circles can look quite fun
#clojure #svg

[adam-james @RustyVermeer]

hacked together a #clojure tool to make little art 'cards'.
With improvements, the idea is to be able to use this on my phone and save the SVGs. Hoping to use it when I get bored in lines or whatever, hopefully leading to some more artistic output

[adam-james @RustyVermeer]

based only on my posts here, what do you think an online course of my own design would/should be?

[adam-james @RustyVermeer]

@LisandroIaffar I happen to love Clojure, so it's basically my first choice all the time :)

I learned Clojure a while ago because AutoCAD has AutoLISP... seemed like there's a bit of history with lisps and CAD tooling, so it kinda feels appropriate

[adam-james @RustyVermeer]

Here's an example of using #clojure to define a data model for CAD geometry and operations. From that model, I can create a STEP file via #FreeCAD and also view/export a meshed solid via #OpenSCAD

[adam-james @RustyVermeer]

Using this approach, I should be able to use my #badspreadsheet to build parametric models and view them rapidly with a web-based 'geometry backend', and then use FreeCAD (or other kernels) to output 'industry ready' formats like STEP, IGES, whatever.

[adam-james @RustyVermeer]

I'm increasingly interested in making 'bespoke CAD tools for makers'. I love #clojure for this sort of thing, but wonder if there are other companies, tools, people that are already doing this exact thing that I can learn from or connect with?

10 minute introduction and demo of Standard Clojure Style: https://t.co/SR4kI73t38

[adam-james @RustyVermeer]

I gave a short talk at #Clojure conj this year showing how I use #badspreadsheet.
It's a tool built with a combo of javascript, Clojure, and #HTMX , and just enough naivety to think I can actually build stuff :)
Give it a watch here:

[adam-james @RustyVermeer]

Here's a fun #badspreadsheet demo. Use a set of draggable points to sketch shapes over an image. Simple pieces, a way to view SVG, a way to get the position of every point, and a way to layer cells over one another. Add some #clojure and you've got a powerful tool :)

[adam-james @RustyVermeer]

Made this in #clojure + quil just for kicks :)
Based on Conway's Game of Life, naturally.

The rules are tweaked slightly (living cells with 0.0 neighbours don't die), and 'dead' cells fade off instead of being set to 0.0 right away.

I think the output is pretty mesmerizing

[adam-james @RustyVermeer]

More #badspreadsheet work. #Clojure, #javascript, mediated by #htmx of course.

Now you can see row/col positions a bit more easily!
Still, UI and usability is tricky.
I'm not sure this is the most readable/usable yet. Curious what others think?

[adam-james @RustyVermeer]

@refset That's right! Most of the c# keys end up providing a list of positions on the grid. Every cell has pos/size, thus a set of positions that they occupy, and the cell code knows how to get cell IDs from positions.
Thanks for the correct link :) Gotta fix the repo up a bit ;)

[adam-james @RustyVermeer]

Still working on #badspreadsheet

Vid of better UI
Key diff is better use of client side changes. Move/translate, then, on the natural action break (stop moving, mouse up, whatever), send data to the backend, render fragments, use #htmx to swap in new html

[adam-james @RustyVermeer]

@htmx_org Your honour, does it help or hurt that I'm Canadian? 🤔

[adam-james @RustyVermeer]

And, circular references don't break things; iterations will auto-stop after a short time (or if iterations coalesce). You can intentionally set up a circular setup and 'advance' the iterations one at a time if you want.

[adam-james @RustyVermeer]

I also came up with a more robust cell referencing approach. I can reference neigbours, cell IDs, rows/cols, regions, and arbitrary lists of positions.
