  1. Re:Not a good test on Leaping the Uncanny Valley · · Score: 1

    No markers in the system whose algorithms I developed.

    If you want to impress you need to do something more than just reproduce a performance from one viewpoint. When my stuff was published we at least rendered animated turntables so you could view all round.

    I'm not saying the method on the video isn't good, it's the video that's the problem. I saw videos 10 years ago that blew me away, but nothing came of them as they were dead-end techniques that didn't allow much in the way of creative variation - the whole point of motion capture in the first place.

  3. Not a good test on Leaping the Uncanny Valley · · Score: 4, Insightful

    Motion capture a face and rerender it from the same viewpoint as a camera used to capture the texture and you'll trivially get something almost indistinguishable from the original. It's only a valid test if you change something significant: move the camera, change the lighting, change the facial features or change the performance.

    Oh no, I wasn't trying to extrapolate based on a trend. I was trying to predict the trend before it even happens using basic knowledge of quantum computing.

    > why is FTL communication equate to backwards in time?

    1. People in different frames of reference measure different speeds. Suppose I'm at rest and a car drives by at 100km/h (as measure by my own radar gun). Suppose a cop car is tailing this car at 105 km/h pointing a radar gun at the first one. They don't measure 100km/h but instead measure the relative speed, -5km/h. So we can take this as a given: different people using different reference frames measure different velocities for the same traveling object.

    2. What Einstein showed was even more dramatic: if in some intertial frame an object is moving faster than light, then there is another inertial frame in which it is moving backwards in time.

    3. What Einstein also showed is that the laws of physics are independent of what reference frame you measure them in. In other words, if you have a device that can propel you faster than light then you must also be able to propel yourself back in time.

    Paragraph 3 is the tricky one. Speaking very vaguely: Einstein unified space and time so that space and time may be rotated into each other. An FTL path that points into the future can be rotated into a vector that points into the path. For more details I suggest reading up on the Lorentz transformation and noting that a Lorentz transformation allows any non-null spacelike vector to be transformed into any other so that a future-pointing non-null spacelike vector can be turned into a past-pointing non-null spacelike vector.

  7. Re:Check out my own single pixel camera on A Single Pixel Camera · · Score: 1
    Yes, narrower beam would be better.


    Illumination from everything else isn't a big deal though. This is a subtle point. Basically, because of Helmholtz reciprocity, this camera is equivalent to one where the photocell is replaced by a diffuse light source and the laser is replaced by a 'inverse laser', ie. a sensor that views only along the path of the laser. Such a camera would react to its environment little differently from a regular camera. Reflections from the environment behave no differently from secondary lighting in a normal photograph.

  8. Check out my own single pixel camera on A Single Pixel Camera · · Score: 2, Interesting

    here. It can grab an image using a single photocell. Note that the photocell (1) doesn't move and (2) collects light over a wide angle and yet I can still produce a picture. Yeah, yeah. It's not as good as your camera. But I don't have a multi-million dollar corporation funding me, just $100.

  10. Incredible Machine on A Definitive List of Gaming Genres? · · Score: 2, Informative

    Actually, Incredible Machine is probably the prototypical example of a 'construction game'. This is basically the genre of game where the player is given a kit of parts and they're free to build stuff with it - often with some goal in mind. Lego might fit this category if it were a video game. I wish there were more examples of this genre, there are only a handful.

    It is done whenever there is a 1 in 10,000 chance of an object hitting the station

    Does this mean that every time they see an object that might hit they're prepared to gamble the entire ISS with 10,000 to 1 odds. So if they see 100 distinct objects with a less than 1 in 10,000 chance of hitting, over the ISS lifetime, there's a roughly 1% chance of one of them hitting? Are these reasonable odds when we're talking about something that cost of the order of $100,000,000,000 to build and carries people.

  17. Re:waiting on Vim 7 Released · · Score: 1

    I don't work over a terminal. I don't use a machine with no GUI facilities. I'm not an old hippie hacker from the seventies. But I still think vim is a better editor than any other out there. And the attraction is simple to explain: it takes fewer keystrokes to get stuff done in vi than with any other editor I know. When you edit you are typically either inserting text, or performing some kind of higher order operation like search or cut-and-paste. So it makes perfect sense to have a modal editor rather than one where you need to signal a higher order operation with some funky key combination.

    Incidentally I was an emacs user 10 years ago. But emacs, out of the box, is unusable. Even after a couple of years of maintaining my own .emacs file there were still useful commands that were many keystrokes away and which required me to write yet another key-binding for. I tried using vi-emulation mode in emacs but that was pretty awful.

    So I'm stuck with vi, with all of its ugly quirks and inconsistencies. As Winston Chrurchill's geeky nephew said, vi is the worst editor ever written, except all the others.

    If nothing else, the lack of present role models for women in scientific fields gives them the message that women can't go into those fields.

    Here is a list of all the role models I can remember looking up to growing up as a young kid enthusiastic about mathematics:
    1. ...er...

    I couldn't name a single mathematician as a kid. I had no role models. I didn't need to see TV programs about mathematicians to tell me that I enjoyed mathematics. I didn't know a single mathematician or scientist. Nobody in my family did science as a profession. Scientists were people in movies who wore lab coats and were the first to die when the experiment went out of control. They weren't someone I wanted to be. I liked mathematics because it was a fascinating subject and I could do it. I didn't do it because I wanted to be like someone else. I did it in spite of the fact that there was incredible peer pressure on me not to do because kids who like mathematics tend not to be the popular kids (until eventually you realise not being stingy with doing other kids' homework gave you a popularity of sorts).


    So tell me please, what do role models have to do with anything? If you need a role model to tell you that science or mathematics or computing is interesting then I think you probably ought to consider getting a job in acting so you can try to be like them all day long.
