  1. Re:C'mon, COMMON SENSE! on Space Elevators Could Be Lethal · · Score: 1

    Last time I checked, energy required was a product of mass and velocity. http://www.1728.com/energy.htm

    So a ship that HAD to reach a non-trivial escape velocity would take a lot more energy than something that could be slowly ratcheted. As I understand it, as you approach zero speed, you actually approach zero energy input (I may be wrong about this).

    Also, a ship must contain its own fuel, an elevator could be powered by electricity or some matter being sent up the tether. This requirement is a HUGE percentage of the total fuel requirement (and the new fuel required to lift the mass of the fuel must have it's own fuel...)

    Also, compared to today's shuttles, it would be incredibly quick (From the planning stage, how long do you think it takes to send a ship into space now? Isn't it still years? Even if it were 6 months which I seriously doubt, a lift would be much quicker)

    >> and it STILL takes just as much actual energy to put anything in orbit...just it does so pathetically slowly.

    So, no it doesn't take as much energy (but your solution does), and it's not terribly slow (your solution requires a more sturdy construction and would probably be much slower)

    I think your whole theory is quite incorrect.

    Might I put fort that perhaps you have become religiously attached to this laser idea and are adjusting, creating and/or forgetting facts to match the way you would like to see the situation? This happens to many people constantly (esp conservatives because it's the nature and definition of conservatism to hang on to concepts and not challenge them)--I'm not trying to be rude, just making a suggestion that you challenge your personal precepts a bit more.

    No, it's never been worth it. If you are trying to decide what to do, and think that maybe you'll try programming--just save us all a lot of time and effort and do something else.

    How come you never see people saying "Should I go into Painting", or "Maybe I'll try Music as a career". When it comes to careers that are art, including programming, If you don't KNOW that's what you are going to do, then you're just not going to do it well enough to make anyone happy.

    When you wonder why virtually all software is buggy, full of delays, poorly designed and shoddily implemented--it's generally because someone is doing a job rather than creating art.

    So then this is one of those cases where "if you have to ask, the answer is NO".

  3. Vote By Mail on Is An Uninformed Vote Better Than No Vote? · · Score: 1

    Give up two hours of your time. Vote by mail and as you are going through the choices, check out the stuff in the voters pamphlet. It's pretty informative and usually shows both sides of the issue fairly well.

    If you have questions after the pamphlet, hit the internet and see if you can find more.

    That said, when it comes down to voting for candidates, I recommend voting for independents whenever you get the chance. It's not really throwing away your vote (the only way to do that would be to vote for a republican or a democrat), but it is showing support for opening up of the current one-party system (the corporate party). If they get 5 percent of the vote, they start to get matching funding which will help them compete.

    Also, why can't cameras do live panning yet? In order to create a large photo you should be able to put it into "pan" mode, tell it how much area you want to capture (so it can set the viewfinder resolution) then move the camera back and forth. It would "paint" the image on the viewfinder as you move the camera around--just keep moving the camera until the entire viewfinder is "painted".

    Wouldn't work very well for moving subjects, but there is nothing technical to this--it's just software. (Well, you have to be pretty good at keeping the lens at the exact same point then rotating around it, otherwise you'd get distortions--but nothing worse than conventional panorams).

  8. Re:greater or lesser evil on Google Under Fire Over Racist Blogs · · Score: 1

    I totally agree, moreover, Google's defining "racist speech" themselves would be horrific, allowing a court to make the decision is the only way it would work.

    I'd like to comment on the stories mention of google's "Don't be evil"... hmmm.. motto? goal?

    I'm getting SO SICK of hearing people quote that whenever google does something they don't like. No corporation can be perfect all the time, and I have trouble believing that any corporation can maintain "Goodness" over a period of decades, but at least Google is trying--at least that's a stated goal.

    Yet it seems that even though they don't advertise "Don't be evil" (It's just something a photographer picked up one day as far as I can tell), I've seen people use it to ridicule Google repeatedly--as though there was something innately offensive about trying to be good to other humans.

    I really don't understand this.

    There is one other thing going on here that I kind of do understand. It seems that people have a natural tendancy to hate popular things they weren't in on. You can see it all the time with Apple (iPod and Mac), Google, VolksWagons, MySpace, rap music, punk music, hell almost every genre of music, etc...

    Although this tendancy seems to be natural and I believe exists to some degree in everyone, might I suggest that if some popular fad bothers you maybe you should get a little introspective about it.

    It's not that all those "popular" things are the best possible, but generally they are popular because they are pretty good, and by being a "Hater", you are really only excluding yourself from something that's probably pretty cool.

    I'm not sure just what causes this--I think shared hatered amoung a persons tight group of friends brings them closer together. Perhaps that also explains the christian/conservative hatered you see spewing from fox and people like Rush L. Perhaps the hatered binds their community in the same way hatered or love of VW's or rap might bind a small group of friends?

  9. They are starting to get smarter... on A Single Pixel Camera · · Score: 1

    I've been thinking for a while that the best way to take a decent photo would be to take a little 1-5 second movie with a wide-spread 1 mega pixel CCD then use the slight movements that you will always get with a hand-held camera to fill in the area between the pixels.

    It occurs to me that if you stuck a camera out the window of a moving car driving down the street you have enough information to make an awesom 3-d panarama of that street (3-d because the moving view gives you the same effect as multiple cameras would for a still-shot). You should be able to see almost all the way around a object (if the camera is a fish-eye you should get very close to a 360 degree view of something that is fairly close to the car.

    Video analysis like this and the ability to break live images from pairs of cameras into 3-d objects inside the computer will be the next computer revolution--possibly as significant as the internet revolution because it will allow computers to interact with people in the real world.

    Many kids, esp. the children of conservatives actually want to have sex with what we'd call a sexual predator. Imagine these conservative parents running around trying to shield their children from everything in the world, and the children trying harder and harder to get into trouble--drugs, gay sex, whatever.

    They can't stop their determined child--nobody can--so they go to the law. This is ineffective as well since there are so many other ways to reach your goal if you're determined to piss off your parents, or just differentiate yourself from them.

    I think the best solution is gradually giving responsibilities over their lives to a child. Scale it so you start when they are 5 and by the time they hit 16, they have 95% control of their lives, 100% when they are 18. Around 10 anything that won't harm them for life should probably be in their control, at 15 anything that won't kill them...

    If they are going to make bad decisions, let them make the decisions when they are 7 and not 17. At 7 you are caught stealing candy and slapped on the wrist--plus you get a really useful discussion with your parents, at 17 you get aids and die.

    The big things about design patterns are that you have a common name for a pattern and some code smells to look for that indicate the need for a pattern. Because you have "Multi-dispatch polymorphism" available, did you use it? Did you know what smells indicated you should use it?

    How is that need replaced by these new languages?

    Also, you say the need for "Design Patterns" is eliminated??? Every single one (is what that statement implies). How would you say the "immutable" pattern is no longer necessary? Simply to say that it's impossible to implement on a "New" language doesn't cut it.

    How about the Observer pattern? You don't need that any more?

    On top of that the biggest thing you learn from design patterns is bad code smells, and trust me you can write smelly code in ANY language.
