OK, I gotta hand it to CoPilot.

Preview is back, but now it's for showing animation. I still don't know how to implement animation, but I know where it's gonna go.
It never gets old. Making little guys move around on the screen is never not fun. Still buggy in the controls, but with the right jiggling the handle, we have animation.

It's gone too far, somebody needs to stop me.
Importing a PNG character sheet. I start with a little dinosaur buddy from Itch.io, and load it straight into Spritely with no processing other than picking the row of little guys I wanted in the animation and cropping it to that size.

This is the image I started from. Not exactly 1:1, but I think it works pretty well for an afternoon/evening and given the limitations of the C64. I'll try to tackle animating overlay sprites at some point, so I can also import that fine black line as a second high res sprite. That's a lot more complicated, though, as it needs to accommodate different resolutions and such. (From here: https://arks.itch.io/dino-characters)

Jebus. Packaging Qt apps is terrible. And, a Qt Quick app is huge. I mean, my binary is under 200k, but by the time the Qt runtime libs are included the install footprint is going to be 10+MB. Obviously still much smaller than the hundreds of MB of an Electron package. But, this still isn't sitting right with me...I set out to learn how to make compact, portable, applications and this aint it.
Qt Quick is nice to develop for, but it's so unpleasant to package and deploy and quite big.

So, I was planning to focus on packaging, documentation, and getting this thing published this weekend, but, I think I'm actually going to use the time to rebuild the UI in something else. Slint has a kinda cranky license, but seems to have a tiny runtime and looks great. Dear Imgui is not really accessible (not super relevant for a drawing program maybe, but if I'm learning a new thing, I want to be able to make accessible software with it, it's the minimal bar for a GUI toolkit, IMHO).

I stumbled on Webview (https://github.com/webview/webview) as an option, which uses web technology for the UI in a way I hadn't even considered, and results in a tiny package and tiny executable with few extra dependencies. Web tech is very accessible. Plenty fast, runs everywhere (Linux, Windows, Mac OS, mobile, BSDs, all seemingly have Webview support out of the box or via a single package install) with minor tweaks. And, web browsers don't break backward compatibility.
Still considering my options. -

Still considering my options.Decided on Slint, after a think on the subject. I've started rewriting, and I guess it won't be terribly painful, but it's going to be at least another week before I can call the thing done.
Seems like a lot just to avoid packaging Qt, but if you think so, you've probably never tried to package Qt (where all deps are bundled, so the user doesn't need to install anything other than the package).

Slint doesn't have a file dialog? What have I gotten myself into? https://github.com/slint-ui/slint/discussions/1959

@swelljoe You rewriting in C++, Rust, or something else?

@swelljoe You rewriting in C++, Rust, or something else?
@matt I'm keeping the C++ back end, which was about half the code (for the sprite objects, various functions for dealing with loading and saving, etc.). At least for now. I may end up rewriting to Rust in the end. The reason I chose C++ was because I thought that got me a better GUI development experience with Qt. But, now that I know I hate Qt (not really, I just don't like the deployment and packaging and runtime story), I don't have any reason to use C++ and I don't really like C++, either.

@lizzard What a quick answer. Did you consider it at all, or just answer off the cuff?
-
@DavidBHimself what if it's not your culture?

@evan 100% yes. I'm very confused why anyone would think otherwise.
Cuisine is part of a shared culture and identity. It's not something owned by anyone. The whole point of a restaurant is to share this culture.

@evan what a question! Of course

DIY TENS Machine is a Pain-Relief PCB
Transcutaneous Electrical Nerve Stimulation (TENS) is one of those things that sounds like it must be woo when you first hear of it. “A trickle of current that can deal with chronic pain better than the pills we’ve been using for decades? Yeah, and what chakras do you hook this doo-hickie up to?” It seems too good to be true, but in fact it’s a well-supported therapy that has become part of scientific medicine. There are no crystals needed, and you’re applying electrodes to the effected area, not your chakras. Like all medical devices, it can be expensive if you have to buy the machine out-of-pocket… but it is just a trickle of current. [Leon Hillmann] shows us its well within the range of hackability, so why not DIY?
[Leon]’s TENS machine is specifically designed to help a relative with hand problems, so breaks out electrodes for each finger, with one on the palm serving as a common ground. This type of TENS is “monophasic”– that is, DC, which is easier than balancing current flowing in two directions through quivering flesh. The direct current is provided at 32 V to the digit electrodes, safely kept to a constant amperage with a transistor-based current limiting circuit. The common ground in the palm is pulsed at a rate set by an ATmega32U4 and thus controllable: 14 Hz is given as an example.
Obviously if you want to reproduce this work you’re doing it at your own risk and need to consult with relevant medical professionals (blah blah blah, caveat gluteus maximus) but this particular sort of medical device is a good fit for the average hacker. Aside from prosthetics, we haven’t seen that much serious medical hacking since the pandemic. Still, like with synthesizing medical drugs, this is the kind of thing you probably don’t want to vibe code.
