  1. Re:Image metadata is the answer on Is 'Fair Use' Unfair To Humans? · · Score: 3, Insightful

    This makes sense to me. According to my publisher, the vast majority of the profit from any new book is made in the first three years. There are a few outliers, but these are the ones where both the publisher and author made so much money in the first three years that they'd still have a huge incentive to bring it to market even if they lost copyright after three years. If you're still making more than a token sum on any book (or piece of music or film) after 7-10 years, it was truly exceptional and you've already raked in a huge pile of cash.

    There are some problems with this approach though, such as how do you deal with incremental changes? There are some FreeBSD source files that I've modified that still have original Berkeley copyrights going back to the early '80s. Would I need to pay several billion to copyright my changes, or would my changes be copyrighted separately and I'd only pay $1 (and would I pay $1 for FreeBSD, or $1 for each one of the several hundred source files I've modified)? If it's the latter, then it becomes very difficult for some third party to work out which parts of a file have lapsed copyright and which still have valid copyright.

    The navy likes them because space is at a premium on a large warship, but with a nuclear power plant energy is not nearly as scarce. If your ammunition is 20% propellant, then a rail gun will let you carry 25% more ammunition for the same space, and that lets you engage in combat for longer between resupply runs.

  4. Re:Obligitory Reagan quote... on Federal Judge Declares Bitcoin a Currency · · Score: 2

    The fact that the currency could be exchanged for real cash puts it in the SEC's realm

    Indeed, but the ruling that it's a currency is odd. The fact that it can be exchanged for 'real cash' means that it's a commodity, and so well within the SEC's mandate. A commodities exchange where you can only trade commodities for other commodities, but have to make the exchanges to currency elsewhere is still an exchange that can be regulated by the SEC.

  5. Re:I'll belive it when I'm holding it in my hand. on Forget Flash: Resistive RAM Crams 1TB Onto Tiny Chip · · Score: 1

    Flash has a number of problems. It's byte addressable, but only block erasable, which means that filesystems that deal with it directly are complex and for the rest you need complex logic in hardware to make it appear to be a block device and it then has performance characteristics that are hard to predict and optimise around. Each generation reduces the per-cell reliability at the expense of capacity, complicating wear levelling and requiring more complex controllers.

    Flash sucks as a technology for persistent storage. The only reason people tolerate it is that spinning magnetic platters suck even more.

  6. Re: Will we finally get a replacement for hard dis on Forget Flash: Resistive RAM Crams 1TB Onto Tiny Chip · · Score: 2

    A Peltier device cools one end and heats the other. You need to dissipate the heat on the other end. If you don't, then the power required to maintain the temperature gradient increases and eventually the heat leaks back. Their main advantage is that they provide a good way of shifting the heat from the small CPU to a big heatsink. They don't magically make heat go away, they just move it.

  7. Re:Will we finally get a replacement for hard disk on Forget Flash: Resistive RAM Crams 1TB Onto Tiny Chip · · Score: 1

    How are you measuring price? Cost per GB? Then they're more expensive. Cost per IOPS? Then they're a lot cheaper. Cost per Watt during active use? Still a lot cheaper. Cost for the amount of storage that you need? Then they may or may not be more expensive: a 40GB SSD costs about the same as a 40GB hard disk, but a 1TB SSD costs a lot more than a 1TB hard disk. If you only need 16GB then the SSD option can be a lot cheaper.

    I wouldn't replace the hard disks in my NAS with SSDs, but there's no way I'd go back to using hard disks in my laptop or in the rack-mounted machines I use for big jobs - the productivity hit would be too great, and my time is worth a lot more than the cost of the SSD.

    If there's sufficient duplication that you don't need to think very much about the report, then you may be even faster with either a template system or an adaptive input device. Editors that autocomplete sentences from a corpus of existing documents can reduce sentences to a dozen keystrokes, which is even faster than most people can speak.

  11. Re:Is anyone else sick of the Apocalypse mame. on 10 Wearable Habitats To Shelter You From the Apocalypse · · Score: 2

    There's a long way between stone age and microprocessor. I couldn't build a transistor, but I do know how to make charcoal, which can make a fire hot enough for smelting, so I could make crude metal tools. There's not much by the way of dark ages technology that is difficult to make. I could also build steam engines, although not very efficient ones given the tolerances of the materials I'd likely have to work with. More importantly, I could build a plow that could be pulled by an animal and know about things like crop rotation and irrigation. It's not a lifestyle that I'd choose, but it's a lot better than living in a cave. If sheep are available, I could even card, spin, and weave wool to make fabric. These things are all fairly basic knowledge that I'd expect a fairly significant fraction of the population to retain.

  13. Re:GET READY.... on Peter Capaldi Unveiled As the New Star of Doctor Who · · Score: 1

    The Time Lords granted The Master a new set of 13 regenerations. There's a lot of implication in on-screen dialog (e.g. The Brain of Morbius) and implicit statements in the Big Finish radio plays that the 13 regenerations is something that's imposed by Time Lord society to prevent stagnation by having some turnover in population. Given that the technology exists and that he's no longer bound by the social obligations of a dead race, there's no reason why he'd continue to be limited to the 13 regenerations.

    The only reason for the limit is that if it's unlimited then it makes the character invulnerable. This is why they portray the regeneration as something traumatic and like a death. Making the technology to grant him another 13 something that was difficult (and dangerous) to access would fill this - he can have another 13 any time he wants, but there's a danger that he'll die trying to get them. The other suggestion was to have someone else take over as the main character. I think they wanted River Song, but that probably wouldn't go down too well. I'd like to see them find Susan and have her inherit her grandfather's TARDIS.

    The NSA, facebook, and google seem to demonstrate that spying on everyone requires shockingly little investment and gets good returns even when you don't know exactly what you want to find in your spying.

    The NSA can do it cheaply because of the existence of companies like Google and Facebook that have centralised systems that a lot of people trust. Google and Facebook only exist because of various economic incentives in the US (some resulting from government incentives, some due to historical accidents), which are not exactly cheap - trying to replicate these conditions in another country would be very expensive. If people were using decentralised communication systems, PRISM would have been a lot harder.
