  2. Finally on Hydra vs. Shredder · · Score: 1

    A number of tournaments featuring the best chess programs had them running on laptops.

    Perhaps that's really a statement of the power of knowledge over the depth of search.

  3. Will Tablet PCs Come of Age? on 3D Holograms Detect Fake Signatures · · Score: 3, Insightful

    Just how much closer are tablet PCs to true handwriting recognition? Authentity aside, handwriting appears to be a simple enough problem, but so much emphasis is placed on context. People can write according to lines on a page. A semicolon shouldn't be confused for an i.

    Now if we can detect forgeries with science, surely the science can be programmed to decide whether I wrote the number 1 or the letter l or even know the letter t is not the letter f and the > is not 7.

    A lifetime of sex can be recorded on one disk without that much encryption. It just sounds like "Yes Yes Yes Yes"

  5. Moore's Law on DVD Player Maker's Margins just $1 · · Score: 1

    Considering the amuont of bang that can be purchased for a buck a $1 margin is a bigger accomplishment now compared to a few years ago. This is a consequence of Moore's law.

    Lower price tags put technology into more homes. The feeling of affordability creates a greater desire to consume. In the long run that should result in a stronger economy.

    These Take Control books are really short (less than 70 pages). I've bought a lot of professional books. Most of them approach 1000 pages. Even the index is over 40 pages.

  10. How Odd on Student Killed Driving Solar Car · · Score: 1

    I am in the Toronto region. All was well when I left Slashdot to go for lunch. It was pouring rain. What is a solar car doing out in such weather?

    Now I'm back and I hear of this

    Solar cars don't make much sense yet. It's better to use solar in a fixed plant and transfer the energy to batteries, which can run even without light. Solar can be used as auxiliary power

    Solar plants in space would make sense since there's plenty of room and sunlight.

  12. Crazy on Human-powered Helicopter Fails to Lift Off · · Score: 2, Interesting

    Two rotors? The blades are so big the drag will make it really hard just to sustain RPMs. If the rotors have independent speeds of course they will smack each other given they are nearly in the same plane.

    Can't tell from the pictures if there really is a gear shift but it doesn't look like it.

    Add a gearshift and use one pair of lift blades as well as a tail rotor

    Shorter blades are likely better. The long blades may require fewer RPMs but the tips of the long blades will be really moving (v = wr) anyways.

    A reasonable design is to take a real helicopter, strip the engine and other paraphernalia out of it and install a multi-person pedal system. Then test the endurance of an average person carrying a weight up a flight of stairs for one minute. Take 1/2 to 2/3 (maybe 1/4 or 1/5 depending on helicopter efficiency) of the maximum weight carryable, divide the weight of the helicopter by this weight to obtain the number of people required to pedal

  13. Re:My degree on IBM Adding Almost 19,000 Jobs · · Score: 1

    Software development experience can be gained by working on an open source project. Also there are plenty of Internet forums where people discuss situations existing in software development serving business interests.

    Then what is really the problem? The symptom is the apparent waste of a good education of advanced computer and mathematic theory. Essentially business goals are not advanced enough. One of the reasons for this I think is not an education system that is so good that it becomes a waste, but actually an education system that strives to look good but does not demand enough. We need schools to show us how to make use of the advanced theory to solve advanced problems. Schools have to force students to solve advanced problems, not just make a quick presentation and pat them on the back for demonstrating a bit of understanding by answering a moderately difficult question on a final exam.

    It's about time students feel they will go forth to invent rather than have enough skills to obtain a job, buy a house, and raise a family. Almost everything a middle class person touches has been produced by a machine. Soon all the services that are done by people will be done by machines. What is left for people to do? Those who do not do better than machines will find that an owner of capital will deem the machines more worthy. In other words, people will lose jobs unless they are willing to use their heads.

    The culture of North America doesn't appear very oriented to inventiveness. Popular TV shows don't pressure people to set higher goals. The literature hardly shows any path from theory to practice or theory to advanced theory.

    When I go on a journey to a faraway place I consult a map on how to get from here to there. Why can't this analogy be applied to negotiating a learning curve? Instead, anyone who wants to gain advanced knowledge does so by running through a maze search algorithm. Enter a branch, find a dead end or a not-too-promising state and backtrack. This kind of chaos exists because people who have found their way through the maze are too busy with new mazes to put many signposts in the old mazes.

    Even though maze handling is a necessary skill for anyone who wants to achieve something great, it ends up turning off a lot of people. Then they pressure schools to just gloss over some advanced theory for the sake of completeness without caring for true understanding and appreciation. So we end up complaining of all the wasted years in school doing things irrelevant to the demands of business.

    Businesses don't really demand anything difficult. They want a bit of management skill, but only a bit. They don't really want advanced theories because that means risk. This risk exists because schools haven't bothered to show students how to be good problem solvers. No wonder businesses just want to make money and avoid problems. The trouble for people is there are some businesses that will take risks by producing machines that will displace the people.

    And why can't we give these companies what they want? Let's gather up the extreme cases of desired skill mixtures and delineate how prospective job seekers can obtain these skills without having to spend years at work or school. The Internet is very useful for informing people how to become an expert in any particular field of tech as long as the basic education background is already in place.

  15. Re:Boom or bust on IBM Adding Almost 19,000 Jobs · · Score: 2, Interesting

    Now if these jobs were in development, there would be more security. Any company hiring 19,000 developers must have solid plans. After a couple of years a lot of people will be gone but there are odds in favor of people still being employed.

    Even if the jobs are not largely in development, IBM must still have some good ideas in order to take such a plunge. Perhaps it smells the blood of competitors or does it feel good times are coming? Or does it want to solidify a position?

    Computer work is women's work isn't it?

    Come to think of it, what do women do? I see a lot of women in health care, secretarial, teaching.

    When I studied computers there weren't that many women, but most of the female students continued into graduate school.

    More and more girls are getting educated it seems due to economic and societal pressures. I guess out of sheer probability the female enrollment in computer science will increase. Computer work nowadays is neither strenuous nor time consuming. It can be done at home. Women with children can still work. It's ideal.

    Aside from the theory of computers, people should not have to be educated formally to be able to do advanced work with computers. Even programming should be somewhat doable by novices.

    Computers are products of our intellect. We control how well computers can be made usable.

    Now, people should realize how fascinating computers really are and get some advanced education about them.

    Regarding how many people are enrolled, the education system should migrate to a computerized teaching system where anyone can learn right now how to do something. One day we should be able to say "Tank I need to ..."

  25. Doesn't make sense on IBM Tells Employees To Hold Off WinXP SP2 · · Score: 0, Offtopic

    I thought a big company like IBM, who started the IBM PC revolution for goodness sake, would have been working closely with Microsoft to keep their customers as happy as possible. Now I see very very few IBM machines on desktops. It all adds up. IBM may be wonderful for inventing new technology but they don't offer anything competitive in terms of price and service to the little guy, especially people with limited computer experience.
