  1. It's the advertisers on Get Your Broadcast TV Anywhere · · Score: 1

    While the terrestrial broadcasters will scream "you're theifing our signal, you bastards," and DirecTV won't give you local channels for the same arguement, that's not the root cause.

    It threatens advertising revenue.

    Advertising is regional, and there's a strangle-hold on the broadcasters to keep it that way. The advertisers want to squeeze every last schekel out of the consumers, and they adjust market prices per the tolerance of each individual market. When the folks in LA (either one) can see the prices advertised in NYC or DC or anywhere else, the ability to maintain regional pricing structures is eroded. Product revenue will decline as pricing awareness will drive the prices down (or at least to some median level.)

    In order to prevent this, the regional broadcasters will provide a "national content" feed that has different "national level" adverts instead of the regional ones. But they'll squeal like a stuck pig if you re-show the DC ads in Chicago. If you're outside of a major metro area, you can get CBSE or CBSW channels on DirecTV. They're the East and West "national" channels for the major network. It's the same programming, only with different adverts. And no, I don't get to watch those channels because I'm too close to DC.

  2. Re: "significant capabilities" on Energia Reveals New Russian Spacecraft · · Score: 1

    The problem isn't just that you need more fuel, but that you need to haul that extra fuel up out of Earth's gravity well. So if you need even more fuel to haul the extra fuel to LEO so you can use it to get to the trans-lunar injection orbit.

    Example - lets assume a linear relationship between fuel mass and imparted velocity (delta-v.) LEO velocity is about 7000m/s. You need to get to about 11000m/s to escape earth's gravity, so let's assume you need about an additional 40% fuel to do the job. That fuel doesn't just magically appear in LEO ready to be used. You had to increase the launch vehicle's initial fuel mass by that amount. Now the beast it heavier, and you need even more fuel/thrust to compensate for it.

    I believe that it's approximately a square-law relationship between delta-v and fuel - i.e. 2x faster requires 4x fuel. (Bear with me, this is Slashdot napkin math, and I'm feeling too lazy to actually do the calcs right now.) So to get the 1.5x delta-v required for trans-lunar injection, you'll need to roughly double the initial fuel mass.

    The Shuttle's engines are impressive. Unfortunately, they're shackled to a crapload of multi-mission deadweight that seriously impairs the system performance. The Shuttle is the wrong vehicle to try to send to the moon. Even if it could stop at the ISS and re-fuel the main tank, it'd never get back.

  3. Re: "significant capabilities" on Energia Reveals New Russian Spacecraft · · Score: 3, Interesting

    The US Space Shuttle has significant capabilities - like returning heavy payloads back from orbit - that even *we* don't use. The primary return-mission for the Shuttle is to return the Leonardo module from the ISS. Leonardo, if you don't know, is a glorified trash can. Hell, if you compare the Saturn V launch capability to the Shuttle, the US space program took a giant step backwards because of the Shuttle (and associated politics.)

    The Shuttle is the equivalent of a pickup truck that's been tasked with replacing tractor-trailers, Greyhound busses, garbage trucks, and NASCAR race cars. Sure, it's capable of performing all those funcitons, just don't expect it to perform any of them well.

    Consider what space exploration would be like today if the Saturn V (or VI or VII) were in service today, in concert with a crew-only vehicle to transport the sentient meat. Use the Saturn booster to take the large, heavy ISS sections into (a useful) orbit, and haul the people up and down on a vehicle designed just for that. And while we're at it, just how do any future missions plan to escape earth orbit (to go places like, say, the Moon?) The Shuttle is incapable of getting out of LEO, so you ain't gonna use that. The Saturn series were the only ones that could get useful[*] payloads into a lunar insertion orbit. The Delta IV Heavy might be able to do it, but it'll be a smaller payload than a Saturn, and it'll be sans meat.

    [*] I use the term "useful" here because it's obvious we can get 1000kg to Mars or to the Moon or to interesting comets. But in terms of establishing a manned presence on another planet/moon, we need to send lots more than that ... and not in 1000kg chunks.

    Play-Doh (now owned by Hasbro) has a toy called the Fun Factory. It's all about extrusions, and even comes with multiple extrusion dice. I'd expect this to be more familiar to the young'uns than a pastry/piping bag. Hasbro even uses the term "extruder" on the website.

  6. Re:Mechanical motivation on Environmentally Friendly Race Cars, Military Vehicles · · Score: 1

    I disagree. There are certainly motovations for altering the vehicle's track. If I can squeeze my vehicle through a gap where the op-for vehicle can't, I've gained a tactical advantage. Example: The Humvee has a high-ground-clearance powertrain that requires a ring/pinion structure on each wheel hub. That's extra weight and complexity, and should have already been removed (by your arguement) in exchange for something that's easier to maintain. The military is willing to pay for tactical advantage in the form of both dollars and effort.

    Also, this new vehicle doesn't have a conventional hard driveline, so the interaction between the suspension and powertrain is going to be fundamentally different from a more conventional structure. Comparing to the complexities of a shaft-driven tank suspension isn't going to give you useful information.

    On a similar note, I was watching the Discovery Channel the other night, and they had a show on about demolition equipment. One wrecker was based on a Cat tracked chassis that could *gasp* alter it's track width. So there's commercial value in such a concept (in spite of the increased complexity and maintenance cost.) Like I said, I disagree with you.

    Second, how much did you pay for said vehicle that your placed on it's lid? Did you pay ... oh, I don't know ... $5k or more? Probably. Did that sudden >$5000 debt plunge you into bankruptcy? No, there's a magical financial instrument to help you out of your situation ... it's called "a loan." Yes, it might take a while to pay off, but you can certainly shoulder the burden (especially if you can afford to putter around in a vehicle in the first place.) Hell, I've been carrying around over $100k in debt since 1991 ... it's called "a mortgage." I'm 10 years into the 30-year loan (refinanced in '94), and I haven't become bankrupt yet. Imagine that!

  8. Mechanical motivation on Environmentally Friendly Race Cars, Military Vehicles · · Score: 1

    The "new Hummer" is driven by wheel-mounted motors, and that provides some extra capabilities you won't find in a conventional mechanical drivetrain. Most noticably, the track (left-to-right spacing between wheels) can be adjusted. That's a huge capability when you have to pack these things into aircraft or ships.

    This vehicle isn't going to completely replace the Humvee, but it will perform certain tasks (like fast recon) much better. The 138hp engine indicates it's not being built as a "do everything" vehicle like the Humvee's supposed to be.

    The electron gun pokes out the side instead of out the back, and there's a parabolic-ish deflector inside the tube to turn the electrons 90 degrees to hit the phosphors. I suspect the technology doesn't scale well. Scan compensation must've been difficult, as each scan line is a different distance from the emitter.

When Verizon finally did roll out service, it was 2x as expensive as the AOL one I already had. I thought it was ironic that Verizon was providing the PHY services for AOL anyway ...

    Verizon's prices have dropped, but AOL's rates have stayed pretty rock solid. It doesn't take a genius to recognize that AOL isn't moving with the market. It's possible that the co-lo contractual requirements are financially prohibitive, too.

    I believe Verizon is rolling out their FTTH serice in my area now, so I think it's time to check out the cost for a big pipe (bypassing the assmunch local cable company every opportunity I get.)

    I agree, but I think the situation is even worse. Some doofus (call him "Bob") with a limited advertising budget is looking to get the most bang for his advertising buck. Most advertising channels have restrictions - either legal or imposed by the BoD (i.e. a magazine for pregnant moms won't carry penis enlargement ads.) Email, however, has little restriction. The spam solution is appealing to Doofus Bob because he gets a gazillion "eyeballs" for the product he's pimping, and he can report to his boss that the "direct marketing campaign is reaching out to X-million potential customers, much more that we could ever achieve through mainstream advertising channels." As long as he maintains the appearance of propriety to *his* boss, then the spamming shall continue. Note that we haven't mentioned anyone actually purchasing said product.

    Advertising is something that's pushed at you. It's going to continue to exist as long as it offers orders of magnitude cost benefits over mainstream channels. If spamming in Country X becomes illegal, that raises the cost of spamming through litigation. It'll just move to a different country where the cost comes back down. Adding spam filters increases the cost through technical means, but not by much - the spammers have the same technology available to them.

    BTW, your grandmother isn't in the target audience, so using her as support for your arguement is irrelevant. The entertainment industry has already abandoned her, and doesn't really expect any revenue potential out of her.

It'll take another two or three generations to purge the "tangible goods" mentality from the mainstream ... but it will happen.

    The physical media will always be present, however. Portable devices like camcorders will see to that. It's the distribution medium that's changing. Up until recently, there hasn't been a viable alternative. To say that "poeple will always do this because that's what we do today" is terribly shortsighted. I personally despise going to the video rental store. It's a PiMA, and I have better things to do with my time.

    The assualt rifle ban was one of those "feel good" pieces of legislation. High-power rifles were never the focus. Lawmakers were aiming to restrict rapid-fire short-barrel weapons that were predominantly used in urban combat evnironments. The final compromises made and the grandfather clauses created a "pre-ban" marketplace that very effectively bypassed the legislation. In summary, it was a complete waste of time.

    Banning "dangerous things" is always a bad idea. I have a hammer. It can be used as a weapon. Should it be banned? The distinction between "tool" and "weapon" has nothing to do with the item.

    While folks may note like ELVs, they're the most economical method for putting payloads into orbit. You aren't carrying around all the Shuttle mass just for the purpose of being able to fly it back.
