comment Java & REST API: How do I check for duplicate before inserting record?
Does listRecords() allow pagination, or can it only return all of the records?

@user93353 The server for which OAuth is a delegate may employ 2 factor authentication when issuing the token, but that's outside of OAuth's purview

comment Is there such a thing as truly random?
Yes, but in that case all bets are off. This is sort of like saying that in the future we may discover that it's possible to travel faster than the speed of light, which would similarly turn physics on its head.

comment Is there such a thing as truly random?
Neutrinos actually carry a small amount of mass, so they would have a greater impact on an electron than a massless photon. But no, there is no way to completely eliminate our error in measurement - at best, our error in measuring the position multiplied by our error in measuring the velocity cannot be lower than 1/2 * h-bar, which is a small enough error that it doesn't impact our macroscopic measurements, but at the quantum scale this error is significant.

The Wikipedia article on the Heisenberg Uncertainty Principle will explain it better than I can, but I'll give it a shot. Essentially, to measure the location of an electron you need to hit it with a photon, which will affect its velocity; measuring its velocity will similarly affect its location. This is a theoretical limit to the accuracy of our measurements, not a practical side-effect to our equipment - by our current reckoning in physics, NO piece of equipment can ever eliminate this inaccuracy.
