Comment Re:One time pad (Score 1) 128

Why not just increase the entropy by just using a compressed version of the text, eg: instead of using the text of the first article, zip it, and use that as the pad (removing headers etc). Or use some compressed H.264 youtube videos as the pad (arithmetic coding pretty much guarantees a relatively high entropy).

Comment Re:"NVidia Hopes to Sell"... CUDA (Score 1) 35

To be fair, virtually all of CUDA is reasonably close to standard C++, so the learning curve is relatively small compared to previous graphics-oriented languages, and it's easier to get more gpu !/$ than with OpenCL. NVIDIA is also pretty much the only serious GPGPU HW available, so you're kind of tied to your GPU vendor no matter what language you use.

Comment Latency (Score 1) 239

I wonder what kind of latency they're getting for the controls. Seems like you'd want roundtrip latency to be under 50ms, which best case with speed of light transmission, line-of-sight controls and infinite transmission rate would correspond roughly to a limit of 4000 miles away for the operator... (probably much less in practice since you'd need to account for the time to send visual feedback presumably as a compressed video stream)

So here's what I say: Consciousness cannot arise from an abstract function. Or any kind of function or mathematics or set of commands, or algorythm.

'consciousness' is an inherently **human** characteristic...the perception of it is entirely dependent upon humans

That's a pretty bold statement. My position is that the laws that govern the universe (whatever they may be), do lead to consciousness (since we're here and conscious). And I do believe that these laws (again whatever they may be) are ultimately themselves an abstract construct that form our reality (but the only difference between abstract and reality is that "physical reality" is equivalent to "perceived abstract")

I guess it ultimately depends on the definition of 'consciousness'. I see it more as the simple definition (ala Julian Jaynes), of 'capable of introspection', eg: we're not always conscious when awake. At some point this is really purely a philosophical matter: none of it makes a difference in how we live our lives, but I somehow find the abstract very satisfying as it solves the question of "why is there something rather than nothing" without resorting to the anthropomorphic principle.

Max Tegmark recently published a book on the Mathematical Universe, which is along the same lines, though I like to differentiate "abstract" from "mathematical" (as the latter seems like an unnecessary restriction)

My problem with the simulation argument is that you then have to explain the existence of a separate universe in which the simulation is running, so it's doesn't really explain anything (recursive logic), in a way similar to monotheistic religions (A lot of it seems like wishful thinking on the part of software engineers). The interesting part about the general abstract function concept is that the universe would automatically *have* to "exist" if it is possible for consciousness to arise from an abstract function, as the function's existence is perceived by itself.
