a bunch of these files littered everywhere that Windows must have left at some point. But I use a Mac.

Just nitpicking: .DS_Store files are created by MacOS.

Solution: use Linux. It won't add any unwanted files to your SD card.

(Couldn't resist )

Hehe, I manage Linux systems for a living. But I use a Mac to get actual work done.

@3dmntbighker Fair enough. I use Linux everywhere and wouldn't want it any other way. One of my professors once said to me it all boils down to what system fits best to your way of thinking and expectations.

For me, that would mean a slide rule and log tables

I guess that would restrict our future communication to traditional mail then.

Yes. Hand written with a quill, and sent by carrier pigeon.

Don't forget about the sealing wax - we have to make sure it arrives properly unopened!

Signed with a w.a.x. cert?

Two tin cans and a very long piece of string is faster

Now, you spawned the question in my head about how fast the information travels along the string... Is it speed of sound? Or is whatever speed it really is actually the speed of sound?

It's the speed of string of course.

NVP (Nominal Velocity of Propagation) for various substances (where C = Speed of Light in a Vacuum)

Electrical signal,
     open wire "ladder": 95-99% C

Electrical signal, coax: 90 to 93% C

Electrical signal, Cat3: 58.5% C
Electrical signal, Cat6: 65% C
Electrical signal, Cat7: 74 to 79% C

Optical signal, fiber:   67% C

Sound waves on String: HIGHLY dependent on string composition and tension. Given by:

Where Ft is the tension and U is the mass per unit length of string. (SI units)

Example: High E string on a Guitar has a density of 3.09 x 10−4 kg/m, and a tension of about 56.40 N when properly tuned. The above forumula yields about 427.23 m/s.

.

Therefore, we can conclude: Use really thin string, and hold it very very tightly, so that the plucked string between the cans sounds like a guitar High E, then NVP:

String, thin and tight 0.0001424 % C

@danal I knew someone would come up with the answer to this question. Great!
