Could it be that Pioneer isn't really slowing down, but it's just the signal being blueshifted?
According to that guy it seems so. Also there seems to be this notion of "tired light" floating around in various articles trying to falsify the red-shift/distance relation. These theories seems to have problems though. I don't know the weak spots in LaViolette's gravity/light model, but it sure was very interesting. Maybe there's some cosmological paradigm shift sneaking upon us. See e.g., http://www.metaresearch.org!
Perhaps you meant the cool proposed spontaneous photon blueshifting where light is actually blue-shifted according to the strenght of the gravitational potential. This is based on the subquantum kinetics theory rather that GR.
Shannon left us a nice formula to calculate the capacity aka maximum possible throughput EVER
This formula however assumes the AWGN channel (additive white gaussian noise) which is a worst case channel. Typically more realistic radio channels will have a better theroretical capacity limit than this. I think your analysis is quite good though. These results must be hoax.
Everything is on one IC, and there is no inter-IC bus involved. Tapping busses between ICs within a DRM-using device is a good way to break the protection. bunny broke the X-Box by using the fact that not everything is on one IC. Probably reasonable for the Flash world, where this is already the case
I guess in this case the bulk of the memory need not to be on the same chip as the key keeping logic. In fact the drm chip need only to be able to perform some basic cryptographic operations given a chip-specific secret and a global secret. The chip specific secret enables storing whatever sensitve info (media-keys, rights info etc) on an open memory area and the global secret is needed to establish trust between two of them devices. The trick to fool the PRN generator seems limited to a select few with expensive equipment and can only uncover separate media keys. The weak link would be the global secret deep within, but on the day that it is broken maybe that generation of the chip has fulfilled its purpose and a new one is at hand. The old system could be preconfigured to trust some generations of the new system, but a new system would never trust an older system. Once the standards are at place and there is a strong hardware certifying mechanism DRM will sort of work. Together with cell-phones, pc-audio chips and (mp3?)-players it seems natural also generic memory media must be part of this system.
