It be emphasised that this is, at most, half a step from literal Nazi propaganda. The Nazis regularly put out messaging about how costly it was to care for people with disabilities, and used it to justify the murder of around 300,000 people as part of Aktion T4.

Doring more experimenting with userdata operations in #picotron - this time out a particle system with batch drawing. The result: fireworks over Düsseldorf, reflected in the Rhine.

So, finding out userdata operations in #picotron are pretty powerful? Here's real-time handwritten digit recognition in Picotron, with the model updating each frame and only using around 4% of the CPU.

Pulling together some my work on SpaghettiCode into a library for creating dynamic UIs in #picotron. E.g. the column on the right is 30% of the window width, with a minimum width of 80px. Aiming for something kind of like CSS flexboxes?
Hoping this'll be useful for a few projects down the road!

Trying out a theme setting for SpaghettiCode to give an easier/more unified way to change up the colours. I just have a few thrown-together examples at the moment, but I plan to add more and a way for users to define their own.

Adding the ability to edit saved carts, as well as the RAM, to SpaghettiCode - making it usable while sandboxed. Any cart in its appdata folder will be editable. The run button also works to run the loaded cart rather than just what's in the RAM!

Got the file explorer in SpaghettiCode to be quite a bit more fully functioned - you can now drag and drop to move files around, or right click for options like creating new files and folders, cut/copy/paste and delete.

Still chipping away at SpaghettiCode, my #picotron code editor. Currently I'm looking at changing how the autocomplete works - instead of one suggestion, it would give you options you can select using the arrow keys. (also, it can now suggest local variables as well as function names!)

Work on my #picotron code editor, SpaghettiCode, has been delayed a bit by me getting a really nasty case of the flu, but feeling better now and have some exciting stuff cooking. I'm completely re-writing the backend to make it much more stable/faster for large files and also... pod-embedding!

Taken a brief break from SpaghettiCode updates to have a bit more of a mess around with #picotron - some inbuilt linear algebra is really useful!
Keep on climbing up that wall!
Not sure this is going to be a full game but was really fun to throw together as a quick tech demo.

Tests are written just as regular #picotron functions, using assert statements to cause failures. This is similar to my experience with Python testing, so hopefully easy to pick up?
I want this to be as simple as possible, rather than needing to learn some new/complicated syntax.

Experimenting with writing/running code tests from within my #picotron code editor. The presentation is a bit rough and edge cases need fixing, but seems to be broadly working?
As well as a pass/fail, it provides messages explaining fails to the user where possible.

Most of my recent work on my #picotron code editor has been basics (e.g. adding undo/redo) or improving performance, but I am experimenting with highlighting local variables by colour.
Is this helpful? Is it a bit much? Definitely think I'll add options to turn off/adjust.

New feature for SpaghettiCode, my WIP #picotron code editor - it's now possible to have up to 3 files open side by side. You can also have 2/3 copies of the same file open, scrolling independently and staying synced with each other. Thanks to @curseofremy.bsky.social for the idea!

Reached my first milestone for SpaghettiCode, my #picotron code editor - it has the features & stability that I'm (mostly) using it to develop itself.
Now added:
- Loading code from across a cart, so tooltips & autocomplete work across files
- Can jump from a function name to its definition

Having another play around with #picotron - might be a bit ambitious, but trying a code editor with some feature I've been missing.
Very much proof of concept, but have autocompletion of function names and tooltips working - both for inbuilt functions and user defined functions.

Added a few features like zoom and colouring strings and now released my evidence board app for #picotron - String Theory.
Use it to organise information in a *very normal* way which will not appear concerning!

Here's a quokka - trying out a more expressionist style, not totally sure if it worked. Going for joyful and bright. 6"x8" acrylic paints on paper.
