  1. Not really... on Japan Tests Reusable Rocket · · Score: 2

    Carmack's team is building a VTVL rocket, but it's A) manned and B) intended to just do hops. It's intended to be a technology prover, but it's going to be more like a flying rocket chair than a spaceship.

    Plus, his budget is at least an order of magnitude less than the Japanese budget.

    Who says Americans can't do small and cheap? Go John Carmack!

  2. I don't think it will be cheaper. on Books on Demand · · Score: 2
    But conversely, printing out a book where you are is much more cost-efficient than printing it out halfway across the country and paying to warehouse and ship it to you. (How much does it cost to send one book through the mail, even at book rate?) These things should balance out--it might be less expensive to buy that book than you think.


    No, it's not. Do the math: that three cents a page, which is generous, by the way, costs you $15 US for a 500 page book. Mass-producing the same book and shipping it to your local bookstore, it's going to cost you between $5 and $10. If the cost is four cents a page, it's $20 for the same book.

    My point is, you're paying the SAME shipping fees for the materials, the only thing that changes is the point of assembly. And mass-production on dedicated high-speed presses is going to be much much cheaper than one-off production in the local book machine. There is wasteage in the distribution and sale of printed books, granted, and more middlemen, but that's the only thing that makes it even close. That $8 paperback they sell in the store only cost maybe a buck to print.

    Plus, the quality of both paper and printing and binding are likely to be inferior to the mass-produced version.

  3. You know, I'd be more impressed with the survey... on Global Warming: Do You Believe? · · Score: 2
    If any of the people surveyed could even give an accurate definition of the greenhouse effect, as opposed to "global warming caused by bad greenhouse gases."

    300 million sheep are not necessarily smarter than one person.

    Science lesson: the accurate definition of the greenhouse effect, which I thankfully learned in astronomy class, is as follows:

    greenhouse effect, n (1937): warming of the surface and lower atmosphere of a planet (as the earth or Venus) that is caused by conversion of solar radiation into heat in a process involving selective transmission of short wave solar radiation by the atmosphere, its absorption by the planet's surface, and reradiation as infrared which is absorbed and partly reradiated back to the surface by atmospheric gases."

    Mirriam-Webster's Collegiate Dictionary, tenth edition


    In other words, any time any planet has an atmosphere, of any composition, that atmosphere will tend to be more transparent to sunlight than to infrared. So, light passes through the atmosphere, hits the planet's surface and warms it. The atmosphere then tends to hold in the heat which is reradiated from the planet's surface. This is a Good Thing: it helps keep the Earth at a habitable temperature.

    What's even scarier are the people who were TAUGHT the Al Gore version in their classes!

  4. How good is the binding, I wonder? on Books on Demand · · Score: 4

    It says they use a hot-glue binding. That's not encouraging; they can be really cheap and nasty. What good is an expensive paperback book (and it will be at least 4 cents a page, more for color) that falls apart halfway through?

    Now, if they had a quality paperback binding like you find on, say, Penguin paperbacks, that would be different.

  5. They already HAVE it at the local Kinko's! on Books on Demand · · Score: 3

    All of this technology is old stuff that's off the shelf, and all of it is already at your neigborhood Kinko's. You can already bring in a CD and walk out with a full-color hardbound book.

    The difference is that this is all in one unit (though Kinko's may have that by now too), and that the method of distibution and payment isn't in place at Kinko's. Of course, it isn't in place yet with this guy's invention, either.

    The real sticking point, and what this shoddily-researched article fails to mention, is that your insta-book is going to cost you several times as much as a mass-produced volume. Printing out pages one at a time is nowhere near as cost-efficient as printing out thousands of copies at a time. How much is your book coing to cost at 3 cents a page?

  6. Re:Why are slashdotters so hostile to NASA? on NASA In Financial Trouble · · Score: 2
    Fact: most people don't care about space programs and would like to see NASA go back to being a 3-geek university wing in exchange for a nationwide health care program.

    Fact: the prospect of a nationalized American health care system fills most Americans with abiding horror. Two words: Veterans' Administration.

    Space is cute'n'all, but until we discover/develop more efficient and cost-effective ways to get there and poke around, it will remain a very expensive venture of bullshit and speculation with ZERO investment returns for the time being.


    The benefits to medicine alone have made the space program a great investment. Ask the people who built the latest artificial heart if they would have been able to do it without the technology developed for the space program.

    Or, look at the computer industry. Or the benefits of satellites, both for global communications and for learning more about the Earth. Or, hell, mylar, which alone saves millions of lives by being used to line grain silos throughout the world and protect against spoilage.

    What's the use in space exploration if we can't even live well on our own planet ?

  8. Innovation? on Software In The Land That Time Forgot · · Score: 2

    In the video game arena, the Japanese are responsible for MOST of the innovation of the entire planet! (There are innovative American games, but they're definitely the exception rather than the rule.) There are whole categories of video games in Japan that don't even exist in the US (Princess Maker, Dating Sim, Super Robot Wars, etc).

    Part of this may be due to the fact that their market is comparitively huge, and will support more niches, but still...

    Sega's output for the Dreamcast alone had more new ideas than all of the PC games market put together for that year! I'm not saying that to put down Western programmers, but rather to give credit to the Japanese where and when it's due.

    Or how about the TMPGEnc MPEG encoder written by Hiroyuki Hori? It's often called the best in its class.

    Many corporations such as Unisys also have Japanese divisions which are run and staffed by Japanese.

    In short, this isn't much of an article.

    I suppose this will get modded as a troll, and I'm no MS lover, but StarOffice(OpenOffice, whatever) pales in comparision to Office 2000.


    Um, here on Planet Reality, Office 2000 has been rightly labelled as something to avoid. It's got lots of features, but it's just too buggy for professional use. I now have to go over my Word docs page by page in hardcopy to make sure that none of the cross-reference links have spontaneously failed on me (they do that now). Automatic numbering is broken. Version control is unusable (it causes bugs in automatic numbering of figures). Oh, and the Section Break bug from Word for Windows 2 is alive and well!

    In my opinion, Word's usefulness peaked with Word 95, which had lots of useful features and was fairly stable, but has been going steadily downhill ever since. It makes my professional life miserable (I'm a tech writer).

    Man o man I wish I could get a job at a Linux company so I could GET AWAY from Microsoft Office! Someday....

    My hunch is that they actually are keeping salaries down by not allowing school districts to evaluate teachers and introduce competition.


    Not in my old school district. 5-10 years ago, the local paper did a major expose that revealed what the teachers in all the local schools were making (by average salary for each level of senoirity, not by person). God, that article should have won the Pulitzer.

    It turned out that 5 years ago, the average salary for a teacher in my old school district was in the middle 50's. With the whole summer off, and way more vacation during the school year too.

    There's no way in hell they'll loan out wireless cards. Firstly, they'll lose them to absent-mindedness if not actual criminal activity. Secondly, your stewardress is NOT going to help you install it. Remember that your average travelling businessperson is a sales droid and would not be able to install the drivers themselves. Thirdly, there is a major issue with the emissions of wireless cards possibly interfering with the plane, which the FAA is not about to overlook.

    They should also try the tech out in their big truck chassis, where the improved mileage would really pay off when those chassis are used to build cargo vans and Winnebagos. God, an extra $10k would be just a blip on a $100K+ Winnebago, and the mileage would be a huge selling point.
