  1. Re:National security should be privatized on US Nuclear Lab Removes Chinese Tech · · Score: 2

    Anything which won't be known to be a problem before you can cash out your options and stock isn't a problem. Someone lower on the totem pole rocking the boat by researching whether there are problems on the horizon is an immediate problem to be solved.

  2. Re:time to build tech in America on US Nuclear Lab Removes Chinese Tech · · Score: 3, Interesting

    Even if we assume for a moment that Smoot-Hawley caused the great depression (laughable given the size of imports/exports in relation to GDP) the Versailles treaty was going to shit long before it and the great depression ... France had already invaded the Ruhr 7 years earlier, initiating hyperinflation.

    Sure, break all the WTO agreements and see if SA keeps buying US bonds ... a country with energy and food independence can do whatever the fuck it wants with it's trade policies, the US not so much.

  4. Re:Congestion & old nets = little benefit on The Future of 802.11ac · · Score: 1

    It helps against interference and attenuation ... but competing routers aren't treated as interference. Once they can beam it tight enough that the CSMA/CA algorithm is adapted to take it into account (ie. the spec allows one router to simply shout across a competing one with a directional signal) then things will change. I don't think beam forming with 4-8 antennas will be nearly tight enough to allow that.

  5. Re:Hoping for indoor range improvements on The Future of 802.11ac · · Score: 1

    Get some extra wlan routers, put them at intermediate points and bridge to different channels to extend the range (repeaters make inefficient use of channel bandwidth). Not entirely trivial to setup but perfectly doable even with cheap routers.

  6. Re:Congestion & old nets = little benefit on The Future of 802.11ac · · Score: 1

    Unless they start putting phase array antenna's on APs to tight beam data to devices there is simply no avoiding time sharing channels... still for a given time on a channel it still gets more data through it, so even in congested situations it helps.

  7. Re:RTFM on DARPA Wants Wireless Devices That Can Blast Through the Noise · · Score: 2

    The problem of course is that you don't necessarily know for certain the space of the gaps ...and by the time you detect a collision you already fucked up part of the aggregate bandwidth (or in the case of UWB raised the noise floor). There is no protocol agnostic solution to that problem.

    I imagine the final implementation will be massively ad-hoc with a huge number of specialized algorithms for each part of the spectrum specifically adapted to the common protocols for that spectrum to make sure what you think are gaps are actually gaps.

  8. Re:Don't be ridiculous. on Is Safe, Green Thorium Power Finally Ready For Prime Time? · · Score: 1

    So what of base load? It's not like energy storage is an intractable problem ... hell for a country like say Switzerland it's a solved problem. Now is economic energy storage for solar/wind a solved problem? No, but then neither is LFTR.

    Renewable energy + energy storage + HVDC represents a huge economic risk for nuclear power ... it's easily possible that in the same time scale you can scale up production of say LFTR it will have become entirely irrelevant (unless you want yet another way to make plutonium for nuclear weapons).

    AFAICS the only thing liquid sodium reactors have ever done well consistently is having expensive to clean up leaks.

    They haven't shipped and the device hasn't been used commercially ... 3D Systems is basing their suit completely on supposition. No way in the world even the dumbest jury in Texas would judge it infringement if they simply removed the feature, no the real problem is that they are going to drag out the proceedings to run up legal costs.

    They didn't get the idea independently, it's just that stereolithography is really old already.

    The real patents have expired and that patent on using weak points to allow breaking off the supports should never have been granted.

    The conclusion is based on statistics most of which are derived from a global economy which has allowed the US to run a continual trade deficit for half a century ... or in other words, a complete fucking joke which will be obliterated entirely when the petro dollar system collapses.

    Which means that because there is no pressing need for it, it will devalue immensely ... the fact that it will likely hold some value is not denied, that it's a very good investment for the eventuality of societal collapse is disputed. You can earn a lot more gold by stock piling non perishable necessities and taking the gold people sew into their clothes after the collapse than you can get before the collapse.

    I'd start selling my guns and bullets for protection, with a semi-feudal system to keep order ... you already have wealth in the form of non perishable commodities, moreover a lot of that wealth is fine grained and easy to trade (bullets make excellent currency if they are in limited supply). You'd have no pressing need for gold, but you would have a pressing need for security ...

    I think someone at Microsoft is too busy trying to imitate Apple and still a bit upset about Intel supporting Linux so much ... Intel is the natural partner for Microsoft at this point, x86 and full backwards compatibility to PC software would give them something unique ... instead they have an overpriced me-too arm tablet which is just worthless compared to the iPad and Nexus 10 (of course most premium tablets have the same problem, but Microsoft had an alternative and blew it).

    A patent mine field ... I'd rather see say a wide bus to tie it to a FPGA.
