  1. Re:Hmmm .... on Physicists Gear Up To Catch a Gravitational Wave · · Score: 1

    True. Its more like neutrino astronomy in that respect. But fewer people know about that (and I couldn't come up with a good car analogy to make it Slashdot compatible. ;) ).

    Assuming we detect them, being able to do spectroscopy (frequency measurements) and intensity measurements over extended periods to determine rise and fall times of events should be a powerful tool.

    Thanks for pointing it out. My info was a bit old.

    Looks like they put components of H2 in storage and are thinking about using it for LIGO-India. I'd heard of the LIGO-India idea, but hadn't known it would use some of Hanford's equipment.

    Another detector at a long distance from the others would greatly improve the ability to localize the source. Let's hope they can get it built and not just have it remain a proposal.

    There are two more detectors at the Hanford Washington site. A primary one like at Livingston, and a secondary one that's half the length.

    Also, there is an European experiment in Italy, called Virgo. It's currently being upgraded to similar sensitivity to the other 3.

    When they are all working, it will allow the detection to not only be verified, but the time of the events at each detector will let them triangulate the location the wave originated from.

    We're pretty darn sure of gravitational waves, as a Nobel prize was awarded in 1993 for showing that the slowing of a binary pulsar was just the right amount to account for the gravitational waves it would generate.

    These detectors will let us do gravitational wave astronomy much like we do with light and radio waves now.

    The huge news would be if they get all of them working with their maximum sensitivity and didn't detect anything. That would mean something was very wrong with their assumptions.

  4. Word Overloading: on Pharming Attack Targets Home Router DNS Settings · · Score: 3, Informative

    In the life sciences, "Pharming" is using genetically engineered animals, like goats, to produce proteins or other substances, (especially those with pharmaceutical applications).

    Example: Genetically engineered goats that produce spider silk proteins in their milk that can then be extracted from it.

  5. Re:What blows my mind on Surgeon: First Human Head Transplant May Be Just Two Years Away · · Score: 1

    It stems from a very general human response to want those they don't like to die. Even if it means those they love die sooner.

    Whenever this subject comes up, there always seem to be comments like: "We can't let this $group-of-bastards escape death!"

    That, of course, ignores that $group-of-bastards is usually a small minority compared to the larger number of people who would benefit.

    This very argument was made when our now fairly common transplant surgeries were first attempted.

    "other than Alberta"

    Well, Alberta's politics don't fit well with a lot of Canadians. However, it fits quite well with our western states just to the south. So, strictly as a favor to help you out, all us US-ians would be happy to take it off your hands for a small handling fee. We'd even guarantee no pipelines to be built on Canadian soil.

    I admit I haven't looked into it deeply yet, but I suspect it may be able to switch in and out of this mode. Else, you'd have to precompile every thing you run in encrypted form and not be able to use any shared libraries. The binaries would be pretty tubby and performance would suck for the reasons you give.

    Run the license checks and some of the key code that's not very compute intensive in the encrypted space, and then shift context to run things you call to do the heavy work in unencrypted space.

    I don't know if there is journalistic purpose in this. I only know what I feel about it. I've not watched it (or there other videos) and have no desire to.

    I've seen people dying and badly injured before in real life as well as video. I'm not very squeamish about it, but it's unpleasant.

    ISIS desperately wanted people to see this and have it burned into their memory. I have no desire to help them get something they want. The couple of stills I saw from it simply confirmed my opinion of them.

    I was in ABQ in the 90s, and they had things like the Airborne Laser 747 come through, an Antonov AN 124 delivering a Topaz space reactor (had to close Gibson Ave when it departed for worry about the jet wash being over the barriers), etc.

    A lot of the interesting things didn't look all that odd unless you knew what to look for, like extra sensor ports added to them and such (Aviation Week was sometimes a good guide to those). The trestle was already closed, so they weren't getting them for EMP testing so much. Phillips Lab still got a lot of one off planes coming through for things related to R and D.

    The Balloon Fiesta mass ascensions are still one of the most amazing things I've seen. I-25 was a dangerous place to be driving when that happened. everyone was looking at the balloons and not the road.
