  1. Book of the month club? on Amazon To Launch Digital Book Rental Service · · Score: 1

    has also said that the digital ebook library would feature older titles

    If I wanted an old book, why not download it legally or otherwise? To subscribe I have to play games comparing the average price of a years worth of downloads to the annual price of the service. Also I'd feel locked in to only reading stuff from the paid service to maximize my "profit" rather than reading what I actually want to read.

    I'd rather subscribe to a (new) book of the month club. They already have subscription infrastructure, it would all be marketing. Simply offer "Baen New Releases Magazine" for perhaps $5/month and I'm in. More than publishers and marketers, I would like to pay money to subscribe to a favored author, or perhaps a themed trusted editor ("Lovecraftian Subscription", or whatever). Nathan Lowell here's a buck a month, now write me a new book. Or John Ringo or whoever.

  2. Re:I dont want smaller.... on Polymer Gel Shows Promise For Smaller, Cheaper Batteries · · Score: 1

    The problem is that much electrical potential will NOT get rid of the "risk". if you short a high capacity battery no matter what it is made of, it will get really hot. they are not going to eliminate the burning battery syndrome. Better QC does that.

    Internal resistance depends on the combination of battery chemistry and manufacturing technology. If you don't believe me, try shorting out comparable voltage / capacity ancient carbon zinc AA (good luck getting over a couple hundred mA, ask the model rocket guys from the 80s) vs a brand new Nicad (easily dump 50 amps, at least for a very short while, ask the RC car guys about melting connectors).

    There is no inherent chemical or physical reason why you couldn't design/build a high internal resistance and high capacity lithium battery. There are inherent engineering/mechanical/manufacturing/economic reasons why you can not. Think about the electrodes being so thin they practically have to be vapor deposited like a telescope mirror, and then how do you make them structurally stable without wasting most of your weight and volume (and capacity) on structure? If you could build them in orbit, and guarantee to never experience more than a zillionth of a G of acceleration, and guarantee they'd never be moved or touched...

    Unfortunately, this invention does not replace the liquid electrolyte. The "jelly" is a polymer soaked in the liquid electrolyte, which definitely is immobilized (thus protecting against leaks) but it's probably not fireproof (I could not find a reference to a research article).

    Very much like how a "gel cell" lead acid battery still contains H2SO4 it just won't pour out as fast if the case cracks.

    I have accidentally cracked gel cells in old UPSes, etc. Its just as corrosive as plain battery acid, it merely doesn't pour out as fast.

    Sure. But the Turing test is a piece of garbage too. I have a deep respect for Allan Turing, and all that he has done for science. But the Turing test was death to AI the moment he proposed it. It MUST be forgotten and burried, and maybe incidents like these can help us achieve that!

    Eh, its more of a thought experiment. Its like making fun of Heisenberg because you want experimental proof of quantum dot technology LEDs, not dead/undead cats in a box with a source and a geiger counter. Einstein had some legendarily weird thought experiments too.

    Its value is in making you think of contrived, yet vaguely familiar situations in a really strange problem space. Not much value in an experiment design engineering planning review meeting.

    As part of a previous job I occasionally got involved as an engineering contact in telco service monitoring situations. You know, like every time we call long distance I hear echo, that type of thing. Trust me, most human to human conversations are pretty F-ing unintelligent, so I think an Artificial Intelligence would not be challenged in outperforming them. PHBs talk meaningless buzzwords to each other, not just to peons, for example.

  7. Re:Do what? on Why We Don't Need Gigabit Networks (Yet) · · Score: 1

    So basically, you just replaced your Cable Company with an online only service, giving you 50 hi def channels for cheap. That is a GOOD thing, since it takes the LOCAL Monopoly out of TV.

    (oh, and how many houses only have 1 computer ?)

    Our house only has 4 people and 3 TVs, all with mythtv frontends. I could watch live TV on my computer, making 4 streams. It would be very challenging to find 80 megabits of live HDTV to watch simultaneously... Not the "find a signal" but the "worth watching" critera... Assuming its possible, that leaves the other 920 megabits of my "gig" service unused.

    I am uninterested in sports, but I once ate lunch at a sports-bar that could probably make use of a large fraction of a gig, if they showed different streams instead of just the same ball game on all the TVs.

    My guess is we will see "gigabit" service marketed soon with a little asterisk next to the claim that they guarantee it could be up to a gig, guaranteed to never be over a gig. The transport stream will of course only be a couple megs.

  9. Re:Bad summary (what else is new) on North Korea Forced US Reconnaissance Plane To Land · · Score: 2, Insightful

    Do they want to just bury the signal in noise, or are they trying to send false data to lure US and ROK units into NK air and sea space?

    Explain why it has to be binary. If I were running the op in N.K., I'd have a modest yet respectable and noticeable jammer doing mission #1, and a whopping boom-car monster of a jammer doing mission #2. So, they steer out of range of mission #1, trust their instruments, and therefore fly into the side of a mountain because of mission #2. Insert N.K. version of simpsons "ha ha" voice. Don't get all moralistic as if we wouldn't do the same to a nation that had air superiority over us...

    The other reason not to fly is its WAY too tempting to the pilots to fly right at the boundary of "GPS works" in other words proving the jammer works against our machinery at a specific exact range. Why participate in an intel gathering activity against our own guys? We can try to work around that by intentionally flying into the jamming and pretending our GPS works, but they have perfectly good tracking radars that can see our behavior is somewhat different when being jammed (perhaps we only approach while VFR rules apply and we only do mostly level flight?) It becomes the codebreaker problem of them knowing that we know that they know that we know endlessly.

    The other thing is the plane probably costs way more than a million times what the jammer costs, and the jammer might have a 1 in a million chance of making the plane crash into a cloud shrouded mountain or another plane, so if there is no specific mission to accomplish, just warmongering for the sake of warmongering, then there is no economic point in flying under those conditions. The way to "win" is to let the N.K. waste their electricity and labor.

  15. Unlikely on Single-Chip DIMM To Replace Big Sticks of RAM · · Score: 2

    The marketing release implies most of the power is being dropped resistively in the leads instead of in the dies. Just doesn't work that way.

    Think about it for a second... The voltage on the die is only a tiny bit less than the voltage on the bus... You know the bus impedance too so that gives away current flow. Do a little ohms law on that tiny little drop and the tiny little current and compare it to what the die drops.

    Or look at it from a thermal engineering perspective... they put heatsinks on the dies, not on the leads...

    Now there will be some savings, probably lower capacitance and inductance and all that makes life easier for the bus drivers. But you're still gonna roast the dies in the middle of the sandwich. So you got three charcoal bbqs stacked on top of each other. No matter how fancy you make the cooking grate the burgers in the middle are gonna fry even if the guys on the end are raw ...
