 There is an approachable explanation in [1], chapter 16 ("Duration-bandwidth relationships and the uncertainty principle"), that says that the product of rise-time and bandwidth of a signal must be greater than some minimum.[1] Siebert, W. M. (1986). Circuits, Signals, and Systems. McGraw-Hill.
 AFAIK timeshift can use any mount. I tried a USB stick, but it was too slow. Now I'm experimenting with a partition on a second drive.
 Just getting started with it--but I think so, using rsync.
 FWIW, it's not paywalled for me (even in incognito mode).
 Maybe it is just Firefox (128.0.2 Windows 10). I tried it with Chrome and it worked fine.
 gballan 4 months ago Siebert [1] is great for this stuff (z-transform). The Fibonacci sequence appears in problem 7.2.[1] Siebert, William McC.. Circuits, Signals, and Systems., McGraw-Hill, 1986.
 The analogy speaks to the number of paths that need be considered so that, later, we can find the overall shortest path (there are likely other intermediate places that we're also evaluating, along with Toronto). Once we know the shortest path from Waterloo to Toronto, that's the only one we need to consider (on that segment) from then on.
 Strictly speaking this analogy doesn’t hold in real life since paths in road networks are not symmetric.
 I model systems that naturally have block diagrams (modulators, phase locked loops, power amplifiers, channels...). I came to an object oriented approach relatively late, but I would not go back. I don't know about general software, but for simulating physical systems it seems ideal.
 If you like this, you may find the allantools library useful.https://github.com/aewallin/allantools
 That's exactly the library I'm using for my Allan deviation plots. The documentation and interface are written more in relation to testing frequency standards, but works equally as well for gyro data.
 I'm working with hex grids in Python right now: https://github.com/RedFT/Hexy is really helpful.
 Indeed, but timing is key: whether the sweep is before or after the population is substantially vaccinated.
