If you're sending over a single channel (telephone audio, or a radio link, or an optical fibre), then bits/s are natural. In the simplest cases you send one bit at a time

The early 4004 and 4040 microprocessors were 4 bit devices, so no nibbles were natural there

Also one transition can carry >1 bit. With 4 amplitude levels 1 baud is 2 bits/s.

Claire - if you have a 200mV or better DC range on your multimeter - remember PCB tracks have non-zero resistance. Measure the drop from +5 input along the tracks to see who's drawing all the current... (Clearly also applies to ground, but harder with a decent ground plane)

Gebco is great - low res, but world-wide. Oh, and it also covers land! In shallow water keep an eye on vertical datum - different sources used various - and I don't think GEBCO has yet unified them.

There are a few bits of CS that are worth studying (data structures, algorithms and complexity, some of OO) for scientific computing AFAIK they are also possible to study outside a degree program. Your student need not worry - just read good code and ask "how and why"?

Just check that no tasks (e.g firefighting, veh maintenance) require you to be 6 ft tall and 200+lbs - if not then an all-female crew could work. (If so, then recruit some big lassies before you kick us out)

A great call to arms, but totally ignores one thing - who pays and when? Advertising and its needs drive much of the bad side of today's web, and we all pay in prices that include ad costs. In the new world, how are content creators and server costs paid? Can the Patreon model extend that far...

I beg to differ. A map, especially a modern layered 3D GIS map, is a place to display the fruits of your exploration. For some locations I suggest a map is a valid end goal.

That's not a real plotter - it's one of those newfangled inkjet contraptions... Real plotters have sprocket fed paper and a drum (and are limited to 5G pen acceleration - where the ink column breaks up...)
