  1. Re:GPON or Active Ethernet? on 5 More Google Fiberhoods Coming To Kansas City · · Score: 2

    Okay, I searched around and found out a little more. Google's TV box is the GFHD100, built by Humax: http://www.wikidevi.com/wiki/Google_Fiber_TV_Box_(GFHD100) It, and its software is apparently derived from Sage TV, which they acquired a while ago: http://www.geektonic.com/2012/07/google-fiber-tvis-its-htpc-dna-sagetv.html This doesn't answer the 'Active vs GPON' question. Anyone in Kansas with Google Fiber that can answer any questions? Does this box connect directly to the fiber going outside of the house? If so, then a teardown would reveal the chip interfacing to the fiber, which might answer the question.

  2. Re:Destruct of Solid rocket boosters on Early Abort of Ares I Rocket Would Kill Crew · · Score: 1

    The myth of the exploding solid rocket boosters exploding during the Challenger disaster is so strongly believed, even by many of the posters here, that I decided to post the video (assuming Slashdot allows this to go through): http://www.youtube.com/watch?v=j4JOjcDFtBE At 1:40 right after the explosion, you see the still functioning solid rocket boosters take off in two different directions. Considering all the passion shown in these posts against solid rocket boosters, I think you should watch this video a few times. Sometimes it is hard to get over strongly held emotional beliefs. Think about it, every rocket hobbyist is using mini-solid rockets! Can you imagine them playing around with liquid fuels?

  3. Destruct of Solid rocket boosters on Early Abort of Ares I Rocket Would Kill Crew · · Score: 2, Informative

    Speaking as someone who was once in the industry, you don't have to blow up the solid rocket booster. All you have to do is 'vent' it. The way range safety works (or at least how it worked in my day) is that there is a predetermined area that the rocket must stay in during its flight so that if all propulsion is shut off it won't land anywhere where there are people. If the propulsion is still applying thrust, then all bets are off--it could land anywhere including in a crowded city. Thus the destruct system only has to shut off the propulsion, under command when it is noticed that the rocket is heading out of the range safety area. It is burning and thrusting out one end, so blow a hole in the other end or along the side and it no longer has any directional thrust. Solid rocket boosters get a bad rap. They did not explode during the Shuttle disaster. I repeat, they did not explode. Look at the old videos. Because of the O-ring issue, they sprung a leak of flame, which ignited the liquid fuel, which exploded. After the explosion, the now free solid rockets flew off in random directions, after which, I assume, the distruct command was initiated to vent them so that there would be no net thrust, as I explained above. They -never- exploded, even after the liquid fuel exploded right next to them--they kept right on working. Solid rocket boosters are much, much safer than liquid fuel. The only issue is that you can't shut them off. But you can vent them in an emergency which has the same affect.
