  1. Still camera film rewind on Ask Slashdot: Sounds We Don't Hear Any More? · · Score: 3, Interesting

    Reach the end of a roll of film and it auto-rewinds with distinctive hum.

    From a travelogue I wrote in 2003:

    As the light started to dim and elephant to disperse, I heard a familiar hum. The film has reached its end and was now returning to the start. I felt a sense of completeness. Previously, I had toyed with the idea of visiting one of Bangkok's inevitably overtouristed sites. But that now seemed wrong. A rushed viewing of an overcrowded temple in a polluted city was not a fitting close for an epic Asian adventure. Better to stop here, at the last frame of the roll. To end with elephants.

    It was the last photo that camera ever took. Digital cameras today emulate some of the noises of film: film advance, mirror clack (even for those that have no mirrors), but not rewind.

    Actually rewind sounds of all kinds have mostly disappeared. Reel to Reel, audio cassette, VCR tape. Backup tape rewind still happens but not many hear it anymore.

  2. Re:I got an idea on AMD, Nvidia Reportedly Tripped Up On Process Shrinks · · Score: 2

    Build your own fab

    While not a bad idea, it doesn't solve the problem. When you have your own fab, you are pretty much obligated to use it. Even when it is late, low on capacity, or a full node behind. You can reduce this risk by throwing a lot of money at R&D and spare capacity. However, this is more than a little bit expensive. That is why AMD doesn't have a captive fab anymore. They can't afford it.

    TSMC is in the business of making chips. They don't make money if they can't make chips. I haven't heard that Apple or Samsung have an unexpected block buster products at 14nm. That means that either TSMC grossly underestimated demand at 14/16nm/20nm (not likely) or they are having manufacturing problems that are slowing production. If it were just TSMC screwing up, you would bet UMC other fabs would exploiting this opportunity to steal business. Since this isn't happening, it is good bet that a hypothetical AMD or Nvidia fab would have the same production trouble.

  3. Re:"Take your time for a thoughtful response" on How Civilizations Can Spread Across a Galaxy · · Score: 4, Insightful

    Anyway, traveling 16LY is only trivially more difficult than travelling 3LY. The hard part is getting up to speed, and slowing down at the destination. The long coast in the middle is easy, and if you are going fast, it is time dilated anyway.

    Getting up to speed is really really hard. So much so that you can largely forget about taking advantage of time dilation. Unless you can salvage a Bussard Ramjet (current thinking is that it won't work) you are not going to get that fast. Traveling 3LY instead of 16LY means only having to reach 1/5 the speed to arrive in a "reasonable" time. That's a big help. It might be the difference between doable but hard and hopeless.

    SATA is not hard to find. *Dual* SATA is hard to find and dual SATA with dual Ethernet is basically non-existant among ARM boards.

    I have a PCduino Nano that I picked up at a raffle. It's a cute little board but single ethernet means it can't be a router or a firewall. Single SATA means no RAID so it doesn't really have any business being a server either.

    So what's a DDR3L (1.35V) SODIMM? I have no clue what the difference is between LPDDR and something like DDR3L, but you sound like someone knowledgeable enough to answer.

    DDR3L is lower voltage but otherwise identical to DDR3. LPDDR is an entirely different line used mostly in cell phones. LPDDR3 has no relationship to DDR3, just as LPDDR2 had no relationship to DDR2 and LPDDR4 has no relationship to DDR4.

  6. Re:PC with SODIMMs? on Samsung Announces Production of 20nm Mobile LPDDR4, Faster Than Desktop DDR4 · · Score: 3, Informative

    There are no DIMMs for LPDDR, SO or otherwise. The price for low IO power is no termination resistors. The means you only get adequate signal integrity with short, point to point traces. Edge connector buses need not apply.

    SODIMMs use the same DDR protocol as desktop DIMMs, but usually contain fewer chips and wider buses to each chip.

  7. More important: how is this happening? on Terrestrial Gamma Ray Bursts Very Common · · Score: 4, Insightful

    Unfortunately, TFA doesn't suggest the question. Gamma bursts were not expected on Earth because they are created by nuclear interactions. Common for stars and other cosmic objects but not expected in thunderstorms. The source could be electrical, which means they are technically x-rays but at a higher energy then thought possible. Alternatively, there is significant nuclear fusion going on in those storms.

  8. Making ENIAC run again on How the World's First Computer Was Rescued From the Scrap Heap · · Score: 2

    Gleason realized early on that he couldn’t make his portion of ENIAC run actual calculations—such an endeavor would require all 40 panels

    I wonder if Gleason of other preservationists have considered building functional replicas of the missing panels. Doing so would be the first step is bringing the relics to life again as a functioning computer.

    Of course, that would not be the end of the project:

    , not to mention thousands of new components and technical know-how that had long been forgotten.

    But perhaps a workable project to restore ENIAC to working order could inspire the re-discovery of such knowledge. Often of technical knowledge thought to be lost is not really lost, just misplaced. Somebody knows or knows who knows but they need to be inspired to come forward or follow up on their hunch.

    Because person by person is how you hire people. I would think that the last thing we would want would be "take it or leave it" job offers. Look what it has done to cell phone contracts, EULAs, utility contracts, heck just about anything.

    "take it or leave it" works just fine for shoes, hotels, electronic equipment and most everything else we exchange money for. The key is you need enough competition that "leave it" becomes a real, practical choice.

    Despite appearances, there is no "jet" or "rocket" engine. It is a pair of ducted fans driven by a four cylinder gasoline engine.

    It isn't a pack either. The weight of the machine is borne by a large frame that the pilot steps onto.

    What would be the point? You need a rather large, well aimed antenna to reliably receive broadcast TV as anyone who has tried to use "rabbit ears" can tell you. Even the largest phablet is not large enough for such an antenna and no one will want to aim it at the tower.

It also has a screen resolution of 720 x 1280 pixels. That's not bad but it is definitely cut down from the 1080 x 1920 pixels of the full size Z3.

    The page that the Nexus 6 is presented on still has a link to the Nexus 5. My personal theory at this time (unproven) is that they're keeping the Nexus 5 around as their lower-end model, since they don't have anything to replace its price point with. Hell, the Nexus 5 page now shows the device running Android L (Lollipop.)

    While the Nexus 5 is not as enormous as the Nexus 6, it is anything but small.

    Which is the chief problem with the various "mini" models available today. Not a one is actually a small, well featured phone. They are simply old and/or reduced spec phones every bit as big as the first wave of large phones.

    I'm not surprised that there are no planets. Red dwarfs form from very small amounts of matter, and don't have the luminosity or stellar wind to stop the in-fall of matter into the central star. I don't doubt they can form, the same way double stars form, but the odds are lower. Just a lot less initial material to start with.

    What a strange statement.

    1) The star in question was a pulsar, not a red dwarf.

    3) Exoplanets have been found around red dwarfs
    4) Pulsars are the remains of large stars.

    The article mentioned a handful of startups but there is no mention of any of these startups actually producing a product that people can buy. If you actually could buy a product or service from an Intellectual Ventures backed company this would be a powerful affirmation that IV is a real contributor and not just a troll.

    That this PR piece makes no mention of such a product, making it very clear this has not happened. I expect this will never happened. IV startups are not meant to produce and sell product. They are meant to be bought out and bought out for a much larger sum than IV could get from just licensing the IP.

    Now, there is nothing wrong with a startup selling out before it can bring it's product to market but it is a little bit dishonest to plan it that way.

    Which, I suppose is an improvement over IV's normal policy of simply sitting on technology until a practicing entity re-invents it and then suing them. Still, it is a long way from showing that the world is better with Intellectual Ventures than without them.

    The whole point of studies such as this is to find out exactly what is the crap that you need to avoid, really. That part certainly isn't common knowledge.

    IMHO, your point is the wrong way around and likely the real cause of why people are eating so badly as well as getting fat.

    The question is not: "What should I not eat?". The question is "What should I eat?" Eat for nutrition. Eat for the benefits to your body that come from eating a food. If a food does not offer anything you need, don't eat it.

    It is not necessary to micro manage the ingredients in your food to ensure that it doesn't contain anything on the current "bad" list. If you pursue food that is helpful, you are not going to get so much of the "bad" stuff anyway and, for the most, what you do get isn't going to matter anyway.

    Comcast starts at 6Mbps and goes up to 105Mbps. AT&T is running VDSL up to 45Mbps. Unlike at the ADSL generation, they are not required to share and so they don't.

    Any ISP that doesn't run their own wires is doomed to offer increasingly uncompetitive speeds. Sonic has run fiber in a couple of areas but it doesn't seem likely that they will be able to fiber everyone who has service with them now. Or even close.
