    Think of this as an IQ test of a potential employer. If one brings it up, point out to them, in detail, how easy it would have been to determine this wasn't you, then walk out of the interview and be thankful you've dodged a bullet.

    Unfortunately, in reality, if any employers do see this as an issue, they'll never bring it up. They'll just refuse to interview you in the first place, or fail to make you an offer after your interview.

    If you ask, you'll get a vague response like "We don't think you're a good fit".

    Most employers will never give you specific reasons for turning down your application, largely as a CYA move.

  2. Re:A lot less useless the Minority Report on Demo of Spatially Aware Blocks · · Score: 1

    One of the clips toward the beginning of the video actually suggested one of the more realistic applications to me. It looked like someone sorted all the blocks showing sky in the background into one pile, and everything else into another.

    Sorting audio, video, and image files is one of the more tedious tasks in computing.
    Sorting physical objects is something we tend to be a bit better at. Like, pulling all the quarters out of your change jar. You're able to interact with a large number of objects rapidly. Meanwhile, a mouse gives you the ability to interact with one object at a time.

    Say you've just pulled a few thousand images off of the 4 GB SD card in your digital camera. It seems to me, it'd be a lot easier to sort them (by when/where they were taken, who's in them, whatever) if you could see some of them on the table in front of you on a few dozen of these "blocks", sort them into piles in a second or two, and then somehow trigger a "give me the next batch to sort" command, and start again.

    However, there's a somewhat simpler (and probably cheaper) way to make an interface like this work. A pair of VR goggles, a webcam, a handful of objects (card, blocks, whatever) with unique shapes printed them (which you could manufacture for a few cents each) and some simple image detection/overlay software.

    The blocks in TFA will always be at least a couple of bucks each, meaning it's expensive to have more than a few of them to interact with; additionally, they need to be recharged, and they're expensive to break/lose. With the webcam/goggles/image overlay technique, you can interact with as many objects as you want for no additional cost, they don't need batteries, and the replacement cost is trivial. It's a bit more cumbersome (VR goggles), and they don't stack as well, though.

    For example, if we take your example of trying to slow down a truck on a long grade, the batteries would need to be huge to absorb all that power.

    That's the trick with your average diesel locomotive -- they're "hybrids" in that they use a diesel generator to power electric motors, but they have no batteries to speak of. They brake in the same way that a hybrid does, but instead of recapturing the energy, they bleed it off as heat via resistance.

    Apparently there are some locomotives out there with large banks of batteries on board to capture the power, but they're all new models.

  9. About to move to the Java port of Lucene... on Lucene and SOLR Get Commercial Support · · Score: 4, Informative

    We're currently using the Zend PHP port of Lucene. It was nice, because we were able to use all our existing code for loading our PHP objects from the database for indexing. It worked fine, as long as are indexes stayed small.

    Now we have several indexes weighing in at around 300+ megabytes, and Zend Lucene has proven to be absolute crap. It takes seconds of CPU time, and hundreds of megs of ram to process simple queries against these indexes. When tested in Luke, the same queries against the same indexes finish in milliseconds with minimal memory usage. Either the Zend port, or PHP itself is clearly unsuitable for production use on large indexes.

    Either way, we're going to switch it out for Solr ASAP, and we anticipate the development overhead should be minimal -- we'll keep using the same code to load our objects, and pass them to Solr via JSON.

    This post neatly explains the math behind Tesla charging.

    If you do the math, a 10 gallon tank of gas holds about 360 kWh of energy. It'd take 9 days to suck that much power through a 110 volt, 15 amp circuit.

    Fortunately, electric cars are more efficient at converting the energy in their batteries to kinetic energy than gasoline engines are -- they require fewer kWh per mile than gasoline cars, which in turn means you need to "refuel" and store less energy than a gasoline automobile does.

  13. Re:That's it? on Progress On Electric Cars · · Score: 1

    And using electricity means that everyone has a fuel source right at home, ready to go. No new infrastructure. No hazardous or explosive alternative fuels (like hydrogen or LP gas). No special equipment or training. Plug it in... Done.

    That's definitely a great advantage, but in the interest of fairness, there are a few disadvantages:

    1) "Refueling time" is much higher. An energy transfer you could do in a minute or two with gasoline takes hours with electricity

    2) Energy density is much worse. A pound of battery holds a fraction of the energy a pound of gasoline does.

    3) Vehicle "fuel" storage is much more expensive. Gas tanks are cheap.

    Advantages:
    1) Simplified powertrain. It's even possible to eliminate the transmission entirely, which is a pretty large source of energy loss in cars

    2) As you mentioned, infrastructure exists... up to the curb. Fast charging will require upgrades at charging sites themselves. The Tesla Roadster comes with a special 220 volt, 70 amp charging system, which requires some decent electrical work to install (in that it's not just an issue of plugging it in to the wall). The advantage, however, is you can charge a Tesla to its full 220 mile capacity in just 3.5 hours. On a standard, 110 volt, 15 amp circuit, it takes 32 hours to fully charge.

    This isn't so much a limitation of the Tesla's batteries as it's a limitation of just how little energy 15 amps at 110 volts is. It takes a long time to get a gas tank's worth of electricity at that rate.

    there is no reason to park your control station anywhere near the battlefield. The USA is very capable of controlling their UAVs from the continental US, where no opponent outside Russia could likely strike.

    When it comes to communications latency, the time required for a signal to reach an orbiting satellite and return, even at the speed of light, is not trivial.

    Geostationary orbit is 35,786,000 meters out. A laser beamed from the earth's surface takes over 100 ms to reach that altitude, and another 100+ ms to reach its destination. Right off the bat, you're looking at a 400+ ms ping time, which is significantly slower than human reaction time. And it only gets worse if you're going around the globe.

    Using satelites in low earth orbit brings this time down, but not all that much when it comes to getting a signal to the other end of the planet.

    Even in the theoretical absolute best case -- a direct fiber optic cable connection operating at the speed of light (actual fiberoptics operate at a fraction of that speed) on the earths' surface (the lowest "orbit" altitude possible), any given point on the earth's surface may be up to 20,000 km away (1/2 the earth's circumference), meaning a 66 millisecond travel time one-way, or a 132 millisecond round-trip ping. Of course, in reality, this is completely impossible -- a real round-the-globe trip will be well over 20,000 km, and take place at a fraction of the speed of light.

    So, in short, you'll never do better than 132 ms round trip when it comes to getting a signal half way around the earth and back. As a result, there will pretty much always be a significant latency benefit to be had in having your transmitter near your receiver. You can afford to put yourself hundreds of miles from your drone, sure. But you can't expect to fly a drone in China with from a base in Wyoming and hope to have exceptional reaction times.
