  1. Re:Oh noes, I can't drive X miles on Will the Nissan Leaf Take On the Tesla Model S At Half the Price? · · Score: 1

    Tesla's tests are showing 3000 full charge-discharge cycles, but it's not clear to me how that scales when you don't fully charge and discharge the battery, nor do I know the failure criteria.

  2. Re:How much titanium on Under the Chassis: A Look At Tesla's Battery Shield · · Score: 2

    Titanium itself is pretty low cost, material-wise. The cost comes in working it. I just found a retail price of $450/m^2 for 1mm sheet. I'm not sure how thick the plate here is, but it's only about 4x the cost of stainless sheet from the same place. If we assume that the plate is a solid rectangle measuring 60x30cm, then the retail value of the material is $80. I don't think it'd be worth much on the scrap market.

    Anyway, to steal it, you'd have to crawl under the car (12cm clearance), detach the plastic aeroshield, then get the plate off.

  3. Re:Don't blame others for user error. on Is the Tesla Model S Pedal Placement A Safety Hazard? · · Score: 1

    They're not underpowered. They are huge discs (all four are about the same size, even, since the very low center of gravity limits diving) with Brembo-made calipers. That said, the discs stay wetter longer than in ICE cars because the regen takes care of the small reductions in speed. In this case it was too cold for regen, so no difference.

    I think it'd be a good idea to disable the accelerator while the brake is pressed, and simple to add to every car via a software update.

  5. Re:Yikes. on Animal Drug Investigation Reveals Pet Medication Often Doesn't Work · · Score: 1

    You joke, but keep in mind that eye contact is a threatening gesture to most animals, cats especially. They show you that they trust you when they blink and look away. "I trust you enough that I feel comfortable not watching you". This is probably the source of the truism that the allergic person gets all of the attention: The cat lover stares and yells, "KITTY" while the allergic person avoids eye contact and is perceived to be the lowest threat.

    You can squeeze your eyes shut a couple of times and watch cats do the same. It's fun!

  6. Re:A Third Possibility on Heat Waves In Australia Are Getting More Frequent, and Hotter · · Score: 5, Interesting

    There is a nonzero chance that your third possibility is correct. But nonzero is all I'm going to give you. Have a look at the amounts of greenhouse gasses put into the atmosphere by a large natural phenomenon, vulcanism

    Looks like the numbers are from 2009 or so. Summary: It takes ~3 days of humans' output to equal one year of volcanic greenhouse gas emissions.

    The factors that are out of our control contribute a tiny fraction of our total.

    It may be terminology missing; In actual fact all the charging equipment is onboard the car, but the fire officials may be referring the the exterior power cable as "the charger" especially if it's Tesla's High Power Wall Connector. The abbreviation for that, HPWC, could reasonably be assumed to mean High Power Wall Charger.

    The Fremont factory is enormous. They're only using a fraction of it for Model S production, with plans to activate more of it for Model E, etc.

    Given that they own a building that exists and will support their needs for the near- to medium-future, it's unlikely that they would move.

    It actually disenfranchises _more_ than half of the voters. Take California in this election:
    Obama: 5573450 Romney: 3635571
    None of the 3.63 million votes for Romney counted, and 1937878 of Obama's didn't contribute to the election.
    Therefore, 5573449 votes, 60.5%, in California didn't count for anything.

    I don't think it's too much trouble. I drove in South Africa for a few days and only had one "no hands on the wheel, grabbing at the door for the gearshift" moment. If the pedals were rearranged, that would be a problem but fortunately they are not.

    Re: Apple laptops
    I work for astronomers and physicists, so I have an informed opinion on the Mac prefrence:
    It's an OS that comes, supported, on good hardware. Generally there aren't scrabbles to find drivers for hardware or other problems that you Just Don't Want if you travel a lot or have (literally) mission-critical duties. It also runs all of the software that astronomers have been running for decades. They still write FORTRAN. They will riot if you take away the command line.

    The labor cost of buying Dells, for example, and throwing Linux on them can end up being higher than just spending extra for the Mac. It's especially true when something goes wrong and you can take it to any Apple store and get parts or software help, no admin needed.

    Yes, they all love being in the Apple club, too.

    No, it's still in /tmp, but it's immediately unlinked so the file still exists while the flash instance is running. Here's a command line I found to do the /proc digging and relink the files in /tmp for you. (obviously you must run this before closing the flash player that is holding the file in existence):

    for h in `find /proc/*/fd -ilname "/tmp/Flash*" 2>/dev/null`; do ln -s "$h" `readlink "$h" | cut -d' ' -f1`; done

  23. Re:Arizona on Ask Slashdot: Science Sights To See? · · Score: 2

    I'd skip Meteor Crater. It's private land, and they charge a hell of a lot of money to see a big hole. As an alternative, I highly recommend the National Parks in northern Arizona. There are a string of them along the road from Phoenix to Flagstaff, and a ton in the area around Flagstaff. To replace your 'crater' fix, go see Sunset Crater. It's a volcanic cinder cone in the middle of a volcanic field with flows and all kinds of cool formations. For more tech-geekery, Lowell Observatory is right inside the town. They do day and night tours.

    Flag's a good place to jump off from if you intend to see the Grand Canyon, too.

    You should probably get the National Park Pass in any case. It's pretty easy to pay off in two or three big parks.

  24. Re:Could this be done from the ground? on Hubble Directly Images Disc Around a Black Hole · · Score: 5, Informative

    You're right in all of your suppositions. (Except for cloudy day--It's the cloudy nights you have to watch out for :)

    Today's 10m class and tomorrow's 30m class telescopes can do a lot of what Hubble has done, especially when you factor in advanced AO systems like the one that was recently installed on Gemini South (one 50W laser split into 5 beams for correction over a large field). Anything on the ground is cheaper than in space.

    Hubble, JWST, Chandra, and the others can see wavelengths that are absorbed by the atmosphere, no matter how high you are.

    And integration time is a huge factor. The Ultra Deep Field image was over 1.1 million seconds of exposure. It's just not practical to do exposures like that from the ground.

  25. Re:Generates? Wrong tense. on Computer Science Tools Flood Astronomers With Data · · Score: 4, Informative

    In fact, they just started blasting the site. I actually live next door to the LSST's architect, which is pretty cool.

    Astronomers generate a tremendous amount of data, bested only by particle physicists. Storing it all is a challenge, to put it mildly. Backup is basically impossible.
    The real problem is that the data lines that go from the summit to the outside world are still not fast. The summits here are pretty remote and even when you get to a major road, it's still in farm country. And then getting it out of the country is tough--all of our network traffic to North America hits a major bottleneck in Panama, so if you're trying to mirror the database or access the one in Chile, it can be frustratingly slow.
