  1. Re:You will not go to wormhole today. on Physicist Kip Thorne On the Physics of "Interstellar" · · Score: 1

    Well, you're wrong with #2

    Gravity waves travel faster than light, quantum mechanics/physics have things happening faster than light (ie, something affects particle A, it's clone, particle B, far away, is also affected). I may not have the terminology right, so don't jump on that.

    Gravity waves are something some string theorists would like to observe so their pet theories don't get flushed down the toilet, but which have yet to actually be observed, despite the building of expensive observatories to try and find them. When someone disproves Lorentz covariance with an actual experiment, we can perhaps talk.

    The only experimental setup that would seem to work would be a tetrahedral mass array with laser interferometry between the masses out in space somewhere (i.e. instruments like LIGO are not sufficient), and then slingshot a projectile mass to accelerate it to a significant fraction of the speed of light (e.g. 0.1C) and aim it through the tetrahedron on a non-face-normal trajectory at a rough offset. This would have the net effect of having the mass apparently "be not there"/"appear"/"disappear again" from the point of view of the instrument, thus establishing, once and for all, the propagation rate of gravitation. If it's actually an artifact of a curvature of space time rather than something with a particulate carrier, the "instantaneous" appearance and disappearance of the mass will be seen by the detector symmetrically, otherwise not.

    It would cost quite a bundle to run the experiment, just to make some string theorists and other non-relativistic model believers very happy (or very unhappy). Then they can all go looking for their Goldstone bosons and loop quantum gravity and privileged local inertial frames.

    It's worse now that the other USVI Golden Goose (HOVENSA) has shut down. I've seen up-close-and-personal the graft that exists on St Croix...

    Yes, that was a big factor; 90% of the USVI fuel came out of HOVENSA, which was the 10th largest crude oil refinery in the world, and most of the energy production is still diesel. So is most of the desalination infrastructure, from which the USVI derives most of its potable and non-potable fresh water (the rest is from rain from the cisterns, which occasionally have to be refilled).

    Not to mention they lost most of their higher paying jobs, and $100M in tax revenue in the closure.

    Part of the problem is the sunsetting on the Federal Economic Development District status, making it much harder to get an EDC registration, which bumped the tax rate in the area considerably. This mostly has to do with the necessity of working in the context of the university in order to obtain status these days, since the federal government is really wanting to get their hands on Ocwen (William C. Erby's company) and other companies monies, despite previous federal approval.

    It changes the user space sufficiently that the historical text configuration files for logging and other facilities no longer function compatibly with the VSC test suite. If those were changed back, or the test suite was somehow made independent of configuration variances for the purposes of testing, I might agree with you, but as it is, there is no way a systemd based system would pass VSC, and would also likely fail VSX, and the parts of the VSTH and VSRT testing, based on the posix_spawn implementation and XPG/4 compliance.

    What's a "Unix"?

    Is it a system based on AT&T code? If so, how much AT&T code has to still be in it.

    Yes. Legally, all AT&T derived systems are grandfathered in as part of the License agreement which exclusively licensed the trademark to The Open Group for relicensing to third parties. For example, the transferrable SVR3 and SVR4 source licenses I own as a result of being sold surplus Class C computing equipment by Weber State University under their blanket source licenses mean my port of SVR3 to the Amiga I did for giggles, is legally UNIX.

    Is it a system that passes the Single UNIX Specification test suite and whose supplier is thus allowed to license the "Unix" trademark?

    Only if they subsequently license the trademark. If so, then it's UNIX. If they don't license the trademark, even if it passes the tests (which must also be licensed from The Open Group), or if they fail to register a compliance statement, and have it certified, it's not UNIX. Mac OS X, for example, is UNIX. iOS on the iPad, iPod Touch, and iPhone isn't UNIX -- and can't be; certain required interfaces are conditionally compiled out, as a space saving measure, and additional user space commands are not compiled for the publicly released versions.

    Is it a system with a Unix-compatible API?

    No. A system with a Unix-compatible API can pass the VSX, VSTH, and VSRT test suites, but unless the user space is there, it can't pass the VSC test suite, nor can it pass the compilation environment test suite, which include ISO C certification of the compiler and libraries, as well as passing negative assertion tests for namespace pollution on the header files (Linux/glibc/glibc2 have serious header file problems; so do the *BSDs). Android can't pass because it fails on threading API compliance with the VSTH test, partly because of the "Bionic" libc implementation having deficiencies (it would take a small amount of work to pass the VSX tests in that regard, but threads are the biggie).

    No - it's not even a question. Bury the lines and you will remove a large number of causes for power outages.

    Quote correct. Thing is someone has to pay for the upfront cost of burying the cables and it is much more expensive. Where I live stringing wires on poles costs in rough numbers something like $1 per linear foot. Burying the cable costs about $8 per linear foot. (this is semi-reliable info from family who worked in the business and would know) Getting the funds to do any sort of meaningful program of burying wires would likely involve a rate increase which tends to be as popular as a lead filled life preserver.

    In the U.S. Virgin Islands, every hurricane season, the U.S. federal government provides funds to bury the power lines that were knocked down, so it doesn't happen again. And every year, the local government official put 7/8 of the $ in their pockets, and balance the wires back up on the poles again in preparation for the same payday the next year. Locally it's a really well known scam.

    Practically speaking, we should have utility tunnels under the roadways, to solve the problem, once and for all. The major cost in burying is digging and repair, which you can deal with exactly once, and not have to dig ever again, if you have room in the tunnels for the next water main, gas main, or sewer line you want to run, and an access in the tunnel side through a shunt to get longer replacement/new pipes down there. That's just a big hole adjacent to a small section of the tunnel, with access doors up top. The costs for burying then drastically drop.

    (1) It assumes that the door-to-door sales model of whatever solar technology happens to be cheapest on the Thursday they ring your doorbell will result in substantial cost savings which can then be kept back from the consumer as additional profit

    (2) It assumes that the utility companies aren't installing all those "smart meters" so that they can tariff at differential metering rates - in other words, pay you less for the electricity than what they sell it to you at - as they are already doing in some markets (i.e. they pay you the wholesale spot market price, but charge you the retail peak price already in some markets

    (3) It assumes the ITC (Investment Tax Credit), which is set to phase from 30% to 10% by the end of 2016, will be renewed so that you are paying a subsidized price for the hardware (actually, that money would go to Vivint, not the home owner, since Vivint continues to own the solar system themselves, and merely sells the electricity to the customer on a monthly basis; as soon as the phase out hits, look for a price hike)
