Comment Tangled Web (Score 1) 1

It is interesting that many Trademarks can contain a shorter sentence than the typical 140 characters of Twitter, and I guess the creative tweet has as much artistic value as poem, which is written in forms of lines as well, or at least to a written pattern. I don't know how one would enforce it unless the tweets have a "signature tune" to them i.e. a style that makes it distinct to a particular tweet author. I never considered this aspect before, it certainly opens up interesting lines of inquiry.

Comment You Can't HACK a satellite. (Score 4, Informative) 330

As a satellite network controller, I disagree with your post: 1) They didn't HACK anything. The obtained ephemeris data from some online website, and pointed an antenna at the satellite. 2) Satellites have predicted channel allocations. There's a huge database containing the predicted signal levels, filtering, datarates and modulation techniques. If an unauthorized access occurs, the satellite network controllers see it instantly. 3) The only thing a satellite controller can do to negate an unauthorized user is reallocate the beamweights of the footprint to exclude the transmission area. Sure, this may work in Sri Lanka (where I've worked, by the by), but if someone in the US wanted to do the same thing, do you really think Intelsat would create 0dB directive gain in Virginia? I don't think so. Read up on satellite operations. It'll amaze you how little control controllers actually have.
