Comment Re:How about someone who groks the math, comment? (Score 1) 197

Thanks, but the only person to quote for that one (including the poor grammar) is me. I'm glad you enjoyed it. As I just said to someone else who disagrees, "If you put some steel across a span with lots of triangle shapes to it, intuitively you may look at it and say "should hold". I'd probably walk across it willingly. I would not, however, want to count on driving trucks over it regularly without someone with engineering training and rigor applying math and proven science to the problem first."

I'd love to read a real comment (yeah, I know, it's almost like I'm new here) from someone who is actually capable of understanding the math here. It would be great to see a reasonable discussion on the actual implications here.

As to people saying "that's obvious" -- what you can intuit and what you can prove are not the same thing. The only thing prove by a "that's obvious" comment is that the person posting it doesn't have a clue.

actually, many many people are saved by AEDs every day. I've seen it done. In one case at my daughter's school a kid's grandfather dropped during a drama production. A student ran and got the AED our department had placed in the school, a parent used it on the floor of the auditorium. The man WALKED to the ambulance when it arrived a few minutes later.

Comment Re:8.0 percent? (Score 2) 82

But an automatic defibrillator will not shock an arrested rhythm. The machine can only shock specific kinds of fibrillation -- where the heart is fluttering in a disorganized way that doesn't pump blood the way it should. A fully arrested heart wouldn't be detected by the machine. You'd need a trained medic to manually shock in those cases.

Comment There's another one here in Portland, Maine (Score 1) 115

Pretty much the same, on a floating barge here in Portland. Just read an article about it the paper (dead tree version). It's pretty clearly tied to google, that's clear. Also, the registrations of these two barges were a three letter designation and then 0010 and 0011 so there's probably at least one more out there (0001) somewhere and quite possibly at 0000 too.

Comment I doubt Bruce would want you to...not entirely (Score 1) 330

His whole set of ideals and processes is about not having to trust an individual person to make you secure. What he publishes is open, as are the software and techniques he espouses. The point is that if he's not trustworthy there should be people out there that will spot it. Personally, I'm not qualified but I do have some level of trust that there are plenty of people who are and who do check. If not, we're all screwed but there's no point in going down that path.

Comment Re:Freezing the ground is not new at all. (Score 1) 225

I don't really know, but I believe it was far long than that. The point is, it can certainly be done. What they're looking to do in Japan is divert the ground water around that site for some duration. If it can be done, it can be done - how long is just a question of the correct application of copious amounts of both energy and money.
