I'm still just not really comfortable with the ethics of withdrawing source code that you previously published. There are tons and tons of things he could've simply kept to himself on top of his first release, but he chose to take back the entire release instead. Like, he seemingly fully intended it for the public because it's cool and interesting and he wanted to show how it worked, but then he simply changed his mi…

> Makes me doubt he has the public interest in mind at all But why? He's doing what he loves. He's able to support himself doing that. What he chooses to do with the internal product of his labors is his choice. Committing to open source software is a big lift for a lot of people. Maybe he didn't want that.

Once again, I have issue only with his taking it back after already open-sourcing it. It felt disingenuous. That's all. I would have no issue with simply never open-sourcing, but he open-sourced it and then took it back.

He could've never open-sourced it in the first place. He could've archived it and kept the rest of the development private. He could've done anything other than what he did. It's one thing to take back something that you never intended to release, but he fully intended to release it and even made a video about how it's fully open and available, but then he just went actually nevermind.

It's just so, infuriating that he would take it away like this after he told everyone he was giving it out. To me, that act of taking it away takes precedence over whatever I'd think if he'd kept it closed all along.

Edit: I just looked it up and apparently he did keep an archive online. I swear he'd taken it down before and there was a whole thing about this, but maybe he put it back up later? It's here: https://github.com/ange-yaghi/engine-sim

So i'll throw this out there. When I was a growing up back in the 50's (yeah, way back then) I was given a model of a v-8 engine to build. It was clear plastic, had pistons, crankshaft, valves, and little red lights for the spark plugs. Small battery powered motor (I think in the starter motor) made everything go round and rounds. One of the coolest models I ever built as a kid.

This was the Revell 'Visible V8', first released in 1958. https://macsmotorcitygarage.com/revisiting-the-visible-v8/

While fairly realistic in function, the Visible V8 is not a replica of a specific production engine, though it most resembles an early Cadillac or Studebaker V8.

...but that transmission definitely looks like the early 4-speed Hydramatic: http://www.1954advance-design.com/Hydra-Matic-rebuild/index....

The Visible V-8. That made it well into the 70s.

They're still making that model today.

3638 kW / 4878 hp is the most powerful engine I could build with this.

I imagine such an engine would instantly blow itself apart in real life. Basically the simulated version of those tractor pull cars where the engine survives for about 500 rotations before it has to be rebuilt.

Depends on the displacement and other factors. Huge engines in that power range like the https://en.wikipedia.org/wiki/EMD_710 are used in locomotives and other applications like power generation where they run 24/7 at 100% load.

The aesthetic is what I get any time I ask for something UI-like in Claude. But gosh darn it I like the look.

It's almost weird hard Claude trends towards that look. It's so distinct... it can't be an amalgam of the most popular design choices, can it?

Some of it is part of claude code's built-in instructions: https://github.com/anthropics/claude-code/blob/main/plugins/...

    "For calibration: AI-generated design right now clusters around three looks: (1) a warm cream background (near #F4F1EA) with a high-contrast serif display and a terracotta accent; (2) a near-black background with a single bright acid-green or vermilion accent; (3) a broadsheet-style layout with hairline rules, zero border-radius, and dense newspaper-like columns."

Why have a kW/Nm - HP/lbf setting, but no metric/US option for the bore and stroke?

Others here are suspicious of the numbers, but at least for the actual engine in my daily driver which I've dyno'd before, it seems reasonable with around 400HP and 450lbf for a 400ci NA V8.
