I think the difference is that variable is the entire population of coupled adults. Of course not 60% of all couples met online, but I’d believe 60% of couples that met this year met online.

I just set up grocy for this, no smart fridge needed. I have a barcode scanner, then scan everything I buy, and again when I use it

as someone that forgets that they’re in the middle of doing laundry frequently, it was great getting notifications when it was done. I rented a place for a bit that had a smart washer, I actually really miss that.

maintenance and such I’m sure were worse, and I’d much rather it be all local and have open apis, but fundamentally, having a connected washer is actually really nice

I’ve tried vibration sensors on the current not connected wadher, but I can’t get anything reliable enough to be useful

prefix notation doesn’t need parentheses either though, at least in this case. lisp uses them for readability and to get multiple arity operators. infix doesn’t have any ambiguity either if you parenthesize all operations like that.
