Comment Really old idea (Score 5, Informative) 77

This has been in use in sci-fi since the dawn of space opera. It gained sufficient use that it was internalized to the point that it's rarely mentioned anymore, you could even say it's why most sci-fi expects a reliable knowledge of location and date even in the face of miss-folds and unplanned time travel.

Stock Split: No capital gains, you didn't sell/buy anything (value of a share was halved, quantity was doubled)

Credit card: No VAT, the VAT is on what you used the credit card to pay for (at least, in every country I've been in that had VAT).

Sold Home: No capital gains (capital loss, in fact) for the given example.

Comment Re:Earth's rotation (Score 1) 226

Only relative motion matters, aka, in the inertial frame of the source when the leading edge of the beam was emitted, how much has the target moved by the time the leading edge of the beam reaches the detector.

At two points opposite each other on the equator, that distance would be less than 2.3 meters, with only 730km separating the source and target, that distance is only a few centimeters (the source and target have nearly the same velocity)

Physics (and velocities) don't work like that, you can't simply sum them.

If, in a third reference frame, 2 objects are observed to be approaching each other at .75 c, co moving observers in the frame of either object would calculate their respective closing velocity as .96 c

The velocity addition formula is:

s = (v + u)/(1+(v*u/c^2))

Comment Re:But where does that leave our immune systems? (Score 2) 414

It's possible, going by the mechanism being used, that it turns every viral infection you get while on it into the equivalent of a (possibly weak) deactivated virus vaccine. In fact, if it didn't, it probably wouldn't work at all, as it's unlikely it can kill all the infected cells before they have done any viral replication work.

Comment Probably (Score 1) 1002

Depends a bit on what you are working on, but i find one monitor for ssh terminals, editor windows and/or debuggers, one monitor for the client interface and sometimes one for the server interface, makes me more productive than juggling one monitor back and forth with a kvm switch.
