  1. no choice on Google Plans Major Play In Wireless Partnering With Sprint and T-Mobile · · Score: 3, Interesting

    They may be afraid of being made irrelevant by a deal like this, but they're much more afraid of being made irrelevant by a deal with their competitors. Imagine how different the market would be today if the original exclusive iPhone contract had been with someone other than AT&T.

    Besides, one likely end scenario if this goes huge is that Google buys their partners.

    That's going to kill the resale value of the existing Leafs, so if you want a short-range electric vehicle at a good price, there are going to be some great deals in the next two years.

    I run a Tor relay, but I set it up to also allow exit for specific sites, such as Google.

    I don't use Tor much myself, but I figure I'm a step ahead of the game by being in the habit of opening most links in a private browser (killing tracking unless I'm tethered to my phone--thanks Verizon).

  4. Yes, please! on Would You Rent Out Your Unused Drive Space? · · Score: 1

    I just set up a file server (NAS4Free), and it currently has tons of extra space. I would be more than happy to get something back for the extra space until I need it.

    For security, I would hope they set up the file servers as Tor dark sites, so even if the encryption fails, there would be no easy way to track down where the storage is.

  5. HTC EVO 3-D on 3D Cameras Are About To Go Mainstream · · Score: 2

    Remember the HTC EVO 3-D? It had a 3-D screen and took 3-D photos and movies. Remember how the revolutionary technology completely took over the market? No, it was pretty much ignored.

    I had the HTC EVO 4G which preceded it, and it was a pretty good phone for the day (though Sprint's 4G coverage was horrible--I used it once in the years I had it; too bad they didn't start out with LTE).

    3-D has always been a gimmick to attract consumers that has mostly failed. Hollywood is still trying it as a way to get people to have a different experience in the theater from home, but few people seem to care. TV manufacturers jumped on it, but they didn't sell. It's just not something people care about.

  6. Re:SF Economic Plausibility on Why We're Not Going To See Sub-orbital Airliners · · Score: 1

    There's a big difference between making irrational choices and presenting a future world where the systems simply wouldn't work as described. From a writing standpoint, you want your readers immersed in the story, not distracted by inconsistencies that suggest the world as described was not given much thought.

  7. SF Economic Plausibility on Why We're Not Going To See Sub-orbital Airliners · · Score: 5, Interesting

    Yup, this raise one of my big complaints about some SciFi stories: lack of economic plausibility.

    Science Fiction is great for looking at how we might deal with various potential technologies. Readers are perfectly happy to suspend disbelief and accept whatever technology is proposed. What readers aren't willing to do is suspend disbelief and accept people behaving implausibly.

    To write good science fiction, you need to accurately portray people. You can make up the technology, but you have to get humanity right. And that means you have to get the economics right.

    This is exactly the problem I had with reading the Hunger Games. Everything worked, except why would a society with hover cars and other advanced technology have need of the services of the districts? Surely they didn't need coal, and yet they had a whole district dedicated to mining it. The lack of economic sense pulled me out of the book. Instead of thinking about the characters, I was thinking about why the society that was described didn't make any sense.

  8. Re:Video Playback? on AMD Catalyst Linux Driver Catching Up To and Beating Windows · · Score: 1

    Thanks, that's good to know. So many people talk about gaming performance, and at one point the open source drivers were getting good at some 3D without the video acceleration piece.

    As to the other question, I'm probably one of the few people with a HTPC who has a tube HDTV that is 1080i. It's really a great TV (36"), and I don't have to worry about the little one knocking it over. Or maybe the HTPC crowd has lots of early adopters, but the rest have moved on to bigger and thinner.

    The OpenGL stuff is nice for gamers, but what about for the HTPC? How well do the drivers do on video playback acceleration? Can they do MPEG-2 and H264 in HD resolutions with minimal CPU?

    I don't suppose they can play a 1080i video and get the fields consistently correct for letting the TV handle the deinterlacing (or keep it interlaced if the TV is an old tube HDTV)?

    No, they can't legally sell them in the USA anymore without some serious engineering changes. They got a waiver on some of the safety regulations that has expired. They also had a limited contract with Lotus for the bodies.

    So to do a new run of roadsters, they would have to do a lot of engineering and essentially make a new car. Right now, they don't have the capacity in engineering or production to make more models; they're struggling to get the Model X out, and they've got their eyes on the III.

    I wouldn't be surprised if they make a new Roadster eventually, but I would put it at five years out at the earliest.

    Besides, given the performance of the P85D, I'm not sure how much more there would be besides a different body shape.

  13. Re:360K already double-sided on Backblaze's 6 TB Hard Drive Face-Off · · Score: 1

    Thanks for finding that source! I was looking at the list of floppy disk formats on Wikipedia to respond, and it didn't have that.

    80 cylinder, 96 TPI

    This was the second type of 5.25" drive made, and the least popular (and known) of the three types of drives. These double the capacity of the original drive by doubling the number of cylinders (tracks) from 40 to 80. They use the same media as the the 40 cylinder 48 TPI drives, but it is certified (tested) on all 80 tracks, as opposed to the standard disks which were only certified at 40 tracks.

    These drives were never common on PCs, although DEC used a single sided version called the RX-50, in the DECMate word-processor, the DEC Rainbow and several other DEC computers, including the PDP-11 and the VAX.

    Other than the DEC RX-50, these drives were almost always double sided, and recorded in double density MFM. They had a capacity of around 720K. Like the 40 track drives, they used 300oe media, and the drive rotates at 300 RPM

    So apart from one very rare example, if you're talking 5.25" disk floppies, 360K meant double-sided. I expect the vast majority of people cutting out the notches to flip over their disks were using Apple II, Atari, or Commodore computers. In that realm, 90K was SS/SD and 180K was SS/DD. Most users didn't have double-sided drives until the IBM PC started using 360K DS/DD disks.

  14. 360K already double-sided on Backblaze's 6 TB Hard Drive Face-Off · · Score: 1

    Sorry, punching the tab out on the other side so that you could flip the disk over only worked on single-sided drives.

    Single-sided, single-density: 90K
    Single-sided, double-density: 180K
    Double-sided, double-density: 360K

    So if you were already at 360K, you were already double-sided.

    I am just about to build a FreeNAS or NAS4Free box. I was planning on running three 4TB drives to give me 8TB usable, but I'm probably better off with a pair of these. I'm mostly using the storage for TV recording, so the slower speed is fine. If the slower speed also means lower power, then it's a big plus.

  16. In Massachusetts... on Time To Remove 'Philosophical' Exemption From Vaccine Requirements? · · Score: 4, Informative

    Mass. Gen Laws ch.76, Â 15:
    "In the absence of an emergency or epidemic of disease declared by the department of public health, no child whose parent or guardian states in writing that vaccination or immunization conflicts with his sincere religious beliefs shall be required to present said physicianâ(TM)s certificate in order to be admitted to school."

    So there's broad religious exemptions such that anyone willing to claim them can skip the process, but if there is a serious outbreak, then suddenly the exemption goes away. That's not a bad compromise.

    I haven't heard of the state ever declaring such an emergency, but I hope they are ready to do so before an outbreak becomes a full epidemic.

    Mixing up the graphics like that is just wrong.

    Especially when the 2600 version of Pac Man was notorious for being so horribly bad. If only it had looked like that.

  21. Re:obviously they should track the sun on You're Doing It All Wrong: Solar Panels Should Face West, Not South · · Score: 2

    Tracking the sun is out of the question when it comes to rooftop solar on sloped roofs. You're pretty much stuck with having the solar panels match the slope of the roof.

    For ground-based installations or for large flat roofs, you would think it makes sense, but it would seem not, as I see solar farms all over the place (in Massachusetts), and they're all fixed installations. If it made economic sense to track the sun, then I'm sure the large farms would be doing it. Even with the production credits (SRECs they call them here), where you can get upwards of $.50/KWh, they're still not tracking the sun.

    Can someone who has actually looked at the costs of sun tracking comment? I keep seeing assertions like the poster above, but I've never heard real numbers.

    Actually, using electricity to produce fuel is something that can have practical use:

    http://www.theregister.co.uk/2...

    In short, it's relatively easy to deploy a small nuclear reactor (much like one found in a submarine) to an operational base. If the excess power can be used to synthesize fuel, then that fuel doesn't have to be trucked in, which is a massive savings in a combat zone.

    Also, it's a potential way of storing excess production, such as when demand drops overnight.

  23. Electricity vs. oil on Jackie Chan Discs Help Boost Solar Panel Efficiency · · Score: 4, Interesting

    Electricity and oil are both energy. You can substitute one for the other, though obviously there's advantages for certain forms in certain uses.

    For home heating, oil, natural gas, and electricity are all viable depending on the cost. Right now gas is the cheapest and electricity is, in most places, the most expensive. It would take a lot of progress to get electricity to be the most economic solution for heating.

    For aircraft, the weight of batteries rules them out.

    For cars, Tesla is proving that electricity is an option. I know that we just signed a contract for solar panels on our house to produce more than we currently use on the assumption that we'll need the extra production to power our next car.

  25. Re:Easy with Gentoo on Building All the Major Open-Source Web Browsers · · Score: 2

    I agree that it should be easy. My point wasn't to rely on distributors for building. It was that the work has already been done for major projects like the ones listed, so you can get a sense of their build complexity by looking at what they had to do.

    For example, here are some ebuild sizes:
    gcc-4.9.1 1556 bytes
    mythtv-0.27.4 9796 bytes
    firefox-33.0 11698 bytes
    libreoffice-4.3.1.2 18473 bytes
    chromium-40.0.2194.2 18610 bytes
    netbeans-ide-8.0 29367 bytes

    That's a rough approximation of complexity. Sure, you can have a long but simple ebuild with comments and trivial stuff. You can hide lots of complexity in an eclass file. But it's a starting point.

    As you can see, a project that uses a typical autoconf setup like gcc, while a very large project, has a very simple ebuild script. Meanwhile, Chromium and LibreOffice are quite complex. I don't know much about netbeans, but it's the largest ebuild in Portage right now. Other large ebuilds include openldap, ghc, php, and ati-drivers.
