  1. Re:A. C. Clarke on The Moon Has a Fluid Outer Core · · Score: 1

    In Earthlight, yeah. I reckon you could build a good city on the moon around a drill to the lunar outer core. Should be possible to recover energy and useful elements from that depth.

  2. Re:Heat energy. on The Moon Has a Fluid Outer Core · · Score: 2

    It must be that the Moon is a great thermal insulator right now.

    Reminds me that Astronauts working on the surface had to keep their suits as clean as possible to help stay cool. Partly because being dark means you collect more heat from the sun but also because the dust is a good insulator. If the crust is made of the same stuff there won't be a lot of heat flowing through it. I also read that the daytime heat on the moon is gone one metre below the surface.

    > Maybe the core hasn't had enough time to cool entirely. Its a pretty small core.

    A smaller planet cools faster.

    Yes.

  4. Re:Heat energy. on The Moon Has a Fluid Outer Core · · Score: 1

    Well yeah. Its because the moon is in orbit around the sun and the moon at the same time. The orbit has to be fairly eccentric around both so the changing intensity of both fields raises small tides in the lunar crust.

  5. Re:Heat energy. on The Moon Has a Fluid Outer Core · · Score: 2

    I suppose a bit of heat comes from being swung around in the sun's gravitational field, but the crust would feel that more than the core. I don't see why there can't be a lot of radioactive material in the core. Additionally the Apollo heat flow experiment should have shown how much heat is actually being lost through the crust. Maybe the core hasn't had enough time to cool entirely. Its a pretty small core.

  6. Finding heavy elements on The Moon Has a Fluid Outer Core · · Score: 1

    So if the moon started out with heavy elements like uranium, a lot of them will be in the core now, keeping it warm. The crust is mainly light stuff, silicon, etc, with the occasional lump of meteoric iron.

  8. Re:pegged connection == latency, who'd of thunk it on Bufferbloat — the Submarine That's Sinking the Net · · Score: 1

    Jitter is caused by the buffers eventually filling or TCP timing out (registering packet loss), dropping the rate for a little bit, the buffers draining, then TCP upping the rate again as the buffers refill, hiding the saturation, until they're full again. Rinse and repeat.

    Brings to mind a situation where I work. ping times between two sites went like (5,10,20,40,80,160,320,5,10,20.....) all milliseconds. I emailed that to our network guys but they just suggested putting an extra compression device on the link, which I persuaded them not to do. Their solution to latency was always to increase end to end bandwidth.

  9. Re:Seems unfair to me on Aussie Retailers Lobby For Tax On Online Purchases · · Score: 1

    The problem is it isn't the consumers who really pay the tax, it's the retailers.

    The retailers have to add 10% GST to their sale price. They get a deduction of GST from their costs. How exactly do they get stuck with paying the GST?

    Any GST they can't offset they pay to the Government at the end of the quarter.

    I have had friends who've imported $1,000 RC model aircraft that are 30% of full size. These arrive in *huge* boxes and include the 55cc engine.

    Are you guys starting an airline or something? If not that then maybe your UAVs could be used to evade Australian GST.

  14. Re:Garage door on The 10 Best Android Hacks · · Score: 1

    For some reason I get the feeling that it'd be easier to take a cheapie prepaid phone (VM's $20/3 mos, I'm sure there's cheaper out there), disconnect the vibrate motor, connect that to input of a solid-state relay whose output is in parallel with the door button, and changing the ringer settings so that when it's _your_ phone, the phone vibrates instead of mute.

    Yes I believe there are some guys in the middle east who are experts at that kind of hack.

  15. Re:As much about the UI as anything else. on Why Digital Newsstands Stink · · Score: 1

    Its possible that the people on the publishers side who put the app together never realised that. They envisage you stepping through their document one page at a time like a good little luser.

  16. Re:It was a dumb idea on Why Digital Newsstands Stink · · Score: 3, Interesting

    For me its much better to browse an aggregator such as google news or an RSS client for articles and then pick and choose from different sources. Often on google news I will deliberately select a foreign source for a domestic article because they edit the text differently and give it a more interesting slant.

    I don't want to subscribe to all of Wired or The Age or what ever. I will however read bits and pieces of each and maybe I would pay for access to some of those bits.

    So I think the subscription model needs to be rethought around this more disparate way of doing things. For me it would be a lot more use if the Magazine app is more like an RSS app.

    How about poison? Leave out some bird feed but contaminate it with something which will kill them over the next few hours. Many poisons intended for pests are designed to work slowly so the carcass isn't found right beside the poison.
