A bunch of interesting looking ipython notebooks here too: https://github.com/daniestevez/jupyter_notebooks

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.

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).

Siebert [1] is great for this stuff (z-transform). The Fibonacci sequence appears in problem 7.2.

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.

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.

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.

Cool. I confess I don't have this 100% straight, but it must be related to the CRB for range estimation. For time (equivalent to range) tau, [2, example 3.13] gives it as var(tau) > 1/(Eb/N0 * MSB), where MSB is the mean-square bandwidth of the pulse.

You may like Chapter 16, "DURATION-BANDWIDTH RELATIONSHIPS AND THE UNCERTAINTY PRINCIPLE", of one of my favorite books [1].

I don't know him personally, but Igor Carron, the CEO, is legit. See, e.g., his well known compressive sensing blog [1].

Might be worth looking at Sowa's Conceptual Graphs. E.g., [1], talks about time, and links to his book.

Here is another [1]--perhaps not to everyone's taste, but it was influential for me. In particular, the first words of the preface: "The underlying spirit of this treatment of the theory of matrices is that of a concept and its representation."

Perhaps "Computational Science and Engineering" is a better fit for you?

Reminds me of 'pulse position modulation' [1].

Should be called the "Bryson Line" [1] ?

Not sure what level you're after, but try [1].

As I understand it, not good enough for "vehicular communication, industrial control, factory automation, remote surgery, smart grids and public safety applications" [1]. A lot of the improvement is down to the frame structure (i.e., how user and training data are distributed in time and frequency). See "Frame structure" in [1].

Great language: "MOST SECRET" and "TO BE KEPT UNDER LOCK AND KEY" and "It is requested that special care may be taken to ensure the secrecy of this document."

As the article says, Banks' thing is post-scarcity [1]. It's not too difficult to imagine PS as one of two possible steady state conditions for us.

Peirce's diagramatic logic is the forerunner to Sowa's conceptual graphs [0]. Worth a look.

I doubt that the technology choice is so clear cut. I'd guess that the major factors are the group velocity (i.e., the speed of modulation, rather than the speed of a wavefront), the group delay of the analog (roughly 1/bandwidth), and the clock/complexity of the digital stuff (coding and modulation and whatnot). Point-to-point microwave may well be better, but it'd take a while to put a good delay budget together.

This is (AFAIK) the basic idea of Integrated Information Theory: http://www.scottaaronson.com/blog/?p=1799 .
