Is the improvement from using std:variant vs polymorphism just due to the indirection you save on?

Yes, but but but evil regulations and bureaucracy

Can't you convert non-capturing lambdas to function pointers?

That whole mouth brush is also crazy exspensive, while I'd assume Philips' Sonicare line is well and profitable

Yeah, I think they usually move them with tractors that have a special attachment that sort of holds them

They solve completely different problems though

Those giant bucket wheel excavators are also electrically powered, by cables. And they use up to 16 MW, so I wouldn't call it completely unrealistic.

Of course running them over some dirt is easier than through possibly moving water, but still.

I guess probably only take the pill n out of 7 days a week? With the long half life you'd probably get the same effect as cutting the pills

You'd also need to mount them facing up, pretty inconvenient when driving

But them it's more like AI assisted performance fuzzing? Just throw stuff against some measuring harness and see what sticks?

If you translate English literally (a very analytical language) to a very synthetic language (eg. Latin), it also sounds like caveman spreak

tábor is also Czech for "camp" (probably the same in Polish/Slovak, but originally from Turkic I think).

Whether the town or term came first...

Same for the Hussites in Bohemia (although a bit earlier, but pretty similar).

With Jan Žižka they also had arguably one of the best commanders in history, up there with Alexander and Hanibal

The browser connects to a webserver running on the ESP32. Over wifi -> over the air. OTA doesn't mean headless or automatic

GPS is over 1 GHz, but I don't think you need to have a microcontroller running that fast to decode it?

The C++ core guideline support library has it.

What do you mean by move-out unique_ptr? That the not_null ptr type would ne null after it's been moved?

In that case that's just a plain usage error, same as how you could memset it to null.
