  1. Re:Delivery medium on Dish Introduces $20-a-Month Streaming-TV Service · · Score: 2

    What is so interesting about this netflix, hulu, and the like is that the customer is no longer paying for the delivery of the goods :: just the goods themselves.

    What do you mean? Netflix and Hulu give away free broadband ISP connectivity to their customers? And Netflix and Hulu have free massive pipelines and distributed hosting to the internet? Man, that's pretty cool. Just because Netflix doesn't directly own the wires between the content and your house like ye olde cable companies doesn't mean that the customer is not paying for the delivery of the goods.

  2. Protocols on The Missing Piece of the Smart Home Revolution: The Operating System · · Score: 4, Insightful

    No, it's not the OS that's needed, but the protocols. For example the Internet is not an OS - it is a set of protocols built on protocols with more protocols running on top. What is needed for home automation is the protocols allowing a "dumb" device like a sensor or button to be able to connect to something that unifies everything together and lets them communicate. What OS, if any, is running on the devices doesn't matter.

  5. Re:I think its gonna be a long long time on New Proposed Path for Manned Trips to Mars: Let Mars' Gravity Capture Spacecraft · · Score: 4, Interesting

    That article is from 2007. Since then a Sky Crane was used to land the 1 ton Curiosity rover on Mars. I think it's pretty clear that we simply may not land an entire 100 ton payload as a single vessel, but would instead land the various supplies, habitats, and people as separate payloads. Perhaps they all come on a single ship (unlikely), but there's no reason with our current technology that we couldn't land the pieces separately. Worst case would be the humans don't land close enough to the supplies to be able to survive long-term, in which case Plan B is to explore similar to how the Apollo Lunar program did, and head back after several days. Then a later mission would bring another set of people to use the supplies already delivered.

    Does that radar indicate ground speed or airspeed? If ground speed then of course that will drop as the aircraft climbs, although the airspeed may stay the same.

  7. Makes sense on Human Eye's Oscillation Rate Determines Smooth Frame Rate · · Score: 1

    This makes sense. One of the things that drives me nuts about those cheap Chinese no-name Android tablets is the display. They draw every other pixel in a checkerboard type fashion, and if your eye is totally still then you don't notice. However if you move your eye quickly back and forth you can clearly see that only half the pixels are drawn at a time. So there's something about the motion that doesn't allow enough processing time to smooth that out. It's amazing how much our visual processing smooths things and even totally fills in parts that aren't even visible, but that requires an image to be steady at least to some degree.

  11. Selfish states on Who's To Blame For Rules That Block Tesla Sales In Most US States? · · Score: 2

    It depends on how "selfish" the state is. State lawmakers are always looking to increase revenue and income into their state. Since automobile dealers are local, and they get a cut of auto sales, it is beneficial, generically, for states to only allow dealerships to sell cars and get their local, in-state cut of the revenue. So it takes lawmakers that can see beyond that immediate income and have vision enough to embrace the future even if it has some cost to their state.

    Then of course you have states like Texas, that produce oil and gasoline, who don't like Tesla and their new-fangled 'lectric cars, who of course want to make it hard on Tesla because that is a threat to revenue for their state.

  12. Created? on Jaguar and Land Rover Just Created Transparent Pillars For Cars · · Score: 5, Insightful

    Describing a concept, and making a fake CGI video of how it might work, does not mean they have "created it". They haven't even revealed where this is at in the development cycle, and the video is very clearly pure CGI. (for one thing, nothing on these augmented displays will look right except from the driver's perspective, which will be annoying for passengers, and the camera does not show the driver's perspective in this video).

    With the "B column" (the column between the front and back door), why should I have to turn my head >90 degrees to see an oddly shaped screen that shows me what is only right behind the column? When I signal how about show me EVERYTHING to that side of the vehicle on a screen that's, um, like right in front of me so I don't have to take me eyes off the road or crane my neck?

  15. Study explains nothing on Study Explains Why Women Miscarry More Males During Tough Times · · Score: 3, Insightful

    This study "explains" nothing.

    Such a pattern would provide an evolutionary explanation for such culling. It “might be adaptive,” Lee says.

    An "evolutionary explanation" isn't an explanation. WHY do more male fetuses die than female during stressful situations? What is the actual mechanism causing this to happen? The answer to that is an "explanation". Further, given the relatively long time frames involved in human reproduction, how would this trait have evolved to cover such a large percentage of the population when it is only needed during stressful situations?

    Maybe males require more resources from the mother as a fetus, or maybe the difference in hormones is the tipping point that causes more male fetuses to die in these situations. But just because it appears to be beneficial in some way in the vast scheme of things does not mean that it exists because it is beneficial evolutionary or was selected in some way.

    Saying "we found it is beneficial for less male fetuses to be born during stressful situations" does not mean "less males are born because it is beneficial during stressful situations".

  17. Useful on Comcast Sued For Turning Home Wi-Fi Routers Into Public Hotspots · · Score: 4, Interesting

    I live in a rural area, and do dual-sport motorcycle riding on mountain trails in the Appalachians. There is a small "town" where we stop to fuel up and eat, and this place doesn't even have cell phone service. However, I did find that there is an Xfinity hotspot. Actually, I didn't even know what the Xfinity thing was until seeing this story, but it now makes sense why there was a "commercial" hotspot at this little crossroads. They allow two one-hour free trial sessions a month, which just happens to be about the frequency I ride through there, so it has been extremely useful to communicate while having lunch. So I give Xfinity a thumbs-up as it was that or nothing at all (and I do mean nothing) in this one particular place.

    What Comcast needs to do is share just a tiny bit of this revenue with customers whose routers provide this service. It might only amount to a dollar or two a month, but that would be an incentive to have it turned on, and would offset the extra cost of electricity.

    Most of the trailer is CGI, which makes sense at this point. The movie won't be released for another year, so this early on most of the finished shots would be fairly generic CGI stuff that was being worked on in parallel to the main shooting. The hard part is all the editing and incorporating CGI into the shots with the actors, and they've only just wrapped up the shooting this month. That's what they'll be working on for the next several months.

    One thing about the lightsaber scene, at first I was like "that's a lame gimmicky lightsaber", but then looking at it more closely, it doesn't have a pure even glow like a normal lightsaber. It looks more like fire and less refined. So my hunch is that sith guy had to figure out how to fabricate the weapon on his own without any guidance, so it's this crude, barely controlled weapon that has to vent extra energy so it doesn't blow up or melt or something. Yeah, that was a pretty geeky analysis.

    I just fired up an old beat up micro I had laying around last week. At the time it was released, the micro had one of the highest DPI color screens I'd ever seen. Still the SP is my favorite. It was the first Gameboy of any kind with an actual backlit screen, and it was beautiful to behold. Games looked so vibrant and clear compared to the Gameboy Advanced, that they almost didn't event seem like they were the same games. The clamshell design was also new and suited to the device perfectly. When closed it wasn't much larger than the screen, and the cartridge fit flush into the device - it was nice and compact when closed. It was also the first gameboy with an integrated rechargeable battery, and it seemed to last for ages. Really, the SP was the most revolutionary single portable gaming device produced by Nintendo. The one and only thing the SP lacked, which was due to the CPU / cartridge hardware being designed well before the SP came out, was a hibernate / suspend type capability when closed (it still seems to me they could have managed that somehow).

  25. Re:With a RTG, it couldn't have got to the comet. on What Would Have Happened If Philae Were Nuclear Powered? · · Score: 5, Interesting

    No matter how you build them, nuclear Radioisotope Thermal Generators are heavy.

    That's totally inaccurate. I went into details about this a couple days ago when Philae was discussed here. In that case someone said that because it took 10 years to arrive at the comet, an RTG couldn't have been used. I'll just copy/paste my other post since it already covers your statement.

    The lander only uses 32 watts of power. The MMRTG used in Curiosity provides 125 watts of power initially, and 100 watts after 14 years. The mass of that specific RTG (the MMRTG, 45kg) would be too great for use in Philae, but then it also produces 3 times more energy than needed (even after 14 years). RTGs have been made in many sizes for many different applications, so it would simply have been a matter of designing an RTG that produces 40-45 watts of power after 10 years.

    However, one of the main uses of the 32 watts of power required by Philae is just to keep the batteries warm so they don't fail. RTGs produce more "waste" heat than they do electricity. For example, the MMRTG used in the Curiosity rover produces 2 kW of heat, of which 125 W is converted to electricity. The extra heat is used to keep the various temperature-sensitive parts of the rover nice and warm so they don't fail. With Philae, a good portion of the 32 watts of the solar power it requires is just to keep the battery warm. So if an RTG were used, it wouldn't even need to produce 32 watts of electricity since it can keep the lander warm directly.

    Looking at the mass and wattage produced, the RTGs ("SNAP-19") in the Pioneer probes would have been just about perfect for Philae. They produce 40 watts of power and weigh 13.6 kg. Philae's current electrical system weighs 12.2 kg, so that's at least in the ballpark. The RTGs on the surface of the moon, as manually placed by Apollo astronauts's would have been a bit heavy at 20 kg. One of those RTGs was still producing 90% of its power after 10 years.

    The SNAP-9A used in the Transit 5B-2 navigation satellite launched in 1963 weighed 12.3 kg and produced 25 watts of power. That looks about like a perfect fit for Philae, and I'm sure more efficient thermocouplers are available today that could further reduce the weight.
