On the same beat, I'm having a blast growing an intuition about seeing and shaping things in 3D using SolveSpace. I agree with [@tpolecat](https://mastodon.social/@tpolecat ), it is a very tranquil piece of software. Focused, lean, slightly quirky, and it mostly just clicks with the way my brain works.

At a 27MB install size, with a UI that is almost TUI level austere, and five evenly spaced releases since 2013, it is peak software.

My plan is to power up the board in the lab to see if it shows signs of life. That would mean I need to continue searching around the fridge's frame.

Is this a bad idea?

(The fridge is written off as a goner so I'm ready to take *some* risks... But I'm quesy about this board-powered-straight-from-mains setup. And I haven't found meaningful info online about these Bosch boards.)

2/N There is broad copper going from black to a relay, which is why I think it might be the compressor's wire. But I'm not sure what's going on with blue.

When plugged into the wall one way, the switch's wire was live. When plugged in the other way, blue was unfortunately not live.

There seem to be no other accessible modules in the fridge; it's all just wires molded into the frame. At the bottom back (sry no photo rn) the only other things are a large cap and connection terminals.

Chat I'd like some opinions.

1/N I'm trying to see if I can salvage a Bosch fridge (KSV36VL40) that just stopped over the weekend. No lights come on on the control panel, which shows no sign of blown-out parts.

The purple wire goes to the on/off switch, which I verified is connected to mains. Neither blue not black seems to be.

My theory is that blue should go to mains to power the board, and black goes to the compressor.

Stealth preview of the $thing I've been working on: a browser-based SPICE simulator.

Today for the first time I got to run a real simulation and put the result on a chart! This is an opamp square wave generator with a true model for the TL071.

The engine is NGSPICE, compiled to WASM. Most of the effort so far has gone into the schematic editor.

All of the code has ben human-written so far by me, in vanilla JS + HTML/CSS.

After 5 or 10 or 15 years the framework becomes unfashionable or discontinued or bought by a nazi and the $tool you built becomes unmaintainable short of a full rewrite.

I think this is a lot less likely to happen to baseline JS and browser stuff (though also not unimaginable).

By contrast, I'm looking at "ancient," zero-dependency SW like Clipper, PureData, NGSPICE which still compiles off the bat, even to WASM if you want.

But there is more to this. With a framework you inevitably pull in a metric fuckton of dependencies. Each of these adds a risk of vulnerabilities and exploits for both you and the end user.

So you must commit to an endless cycle of updating versions and producing new builds without adding any value.

Then the FX starts sneaking in breaking changes and you must change $tool under the hood, again just to keep up.

For me this partly the path of least resistance: I'm good at JS and thinking about architecture, but not sharp at any one FX like React/Vue/Svelte. If use an fx, then for a few weeks most of my effort would be spent on coming to terms with the FX and not on building $thing.

This way, obviously, I keep getting better at JS and the DOM, but never get good at a framework.

I've been working on a software $thing and I'll soon be ready to start sharing about it. For now I thought I'd ask you what you think about building a browser-based tool without any JS framework.

That is namely my sweet spot: only markup, styles and JS, and esbuild to tie it all it and give me live reload while developing.
