Generally, yes. But remember that there are difficulty adjustments, and it's conceivable that there are two chains, one being a bit shorter but with higher difficulty, and that can have precedence over the longer but easier one. The po

Yes, or you could say a human power is 75 W (but only 8h a day). And the point is that we use some 2000 W, so have the equivalent of 26.6 people working for us nonstop (requiring 80 people total on 7 day a week shift work).

Somewhat related thought: World power consumption is around 20 TW (of which around 3 TW electricity), that's very roughly 2 kW per person (obviously not equally distributed). A human consumes around 8600 kJ of energy in their food per

Why talk about 2.6 kWh/day (power*time/time = energy/time = power) when there is perfectly fine unit for that, namely the watt? 2.6 kWh/day = 2.6 kWh/24h = 108 W, on average.

Exactly. I find the macOS approach (Cmd-Tab to pick the right app, Cmd-` to pick the right window) much faster/better than just one shortcut to go through all windows. Imagine having N apps with M windows each, with the macOS model you

Yes. I think what all mathematicians can agree on is that the layout (and the starting index! :-) is like this: A[1,1] … A[1,n] … … A[m,1] … A[m,n]

What's wrong with the ellipsis? Ensures that it doesn't get distributed across two lines. And with a proper proportional font it looks just fine.

I don't think so. I think MS Word turns space+hyphen+space into space+en-dash+space. (Note "en" not "em".) It might turn two consecutive hyphens into an em-dash (not sure about it, because I prefer space+en-dash+spa

Incidentally, there's a TL;DR app as an alternative to man [0] that just gives you the most common examples/use cases for any command. Quite useful. [0] `brew install tealdeer`, then invoke with e.g. `tldr chown`.

The banking system is fine. It’s just that credit card use is not very widespread in Germany. PayPal (linked to bank accounts) is then fairly convenient online.
