  2. Re:It's entertainment. on Why People Should Stop Being Duped By the 3D Scam · · Score: 1

    Between 20 feet and infinity, the difference between focus is practically nil.
    It may be more of a problem on a smaller screen, though.

  3. Re:Convergence/focus on Does 3D Make Your Head Happy Or Ache? · · Score: 1

    Further than 25 ft, focus distance doesn't make much difference, especially at the resolution of most film. That's probably why Snellen eye charts are placed 20 feet away.

    For me, I don't think the biggest problem with 3D displays is the stereoscopy, rather all the tricks used to achieve it at a relatively low price. I get eye strain watching a 2D trailer (while wearing 3D glasses) before a 3D movie just because the picture alternates between images for each eye. I think Sony projectors show both images simultaneously, but there are none of those near me.

    I actually find red-cyan glasses easier to use for a very short period of time, because the video is smooth, but the color difference leads to worse headaches in the long run. I'll probably be able to handle the 3D on the 3DS.

    That's because most of the dialog for that part came out of Mark Zuckerburg's LiveJournal.

    They sensationalized the beginning part of the blogging, though. In the movie he didn't use a comment tag, and he went off about cup sizes.

    The script for that part was basically taken word-for-word from Mark Zuckerberg's real livejournal page.
    The only major change they made was at the beginning of the sequence when he is typing mean things about a girl. <!-- He actually only said one unkind thing, and it was inside an HTML comment -->

  8. Re:Human video projectors on BitTorrent and Khan Academy To Distribute Education · · Score: 1

    Khan actually agrees with you. He encourages using the information gathered by the exercises to pair those who are doing well on a concept with those who are struggling. This tutoring lets everyone build character and strengthen knowledge, not just the instructor. If any students are still struggling, the instructor can focus their instruction to just those students and just those topics. They have more time to answer questions because they aren't spending a majority of their time giving passive lectures.

    Khan isn't trying to get rid of classrooms, he's trying to improve how they function.

    I'm not sure how well this will translate into subjects not related to math, though.

  10. Re:It's the highest in actual use on YouTube Adds 'Leanback,' Support For 4K Video · · Score: 1

    If you go to a new, spiffy, digital theater and watch a movie like Avatar, it is probably a 4k projector (though some places with smaller screens use 2k instead, which is just a bit higher than 1080p).

    I believe most digital theater screens use 2K projectors... more than 90%, based on how many 4k screens are listed on Sony's 4k page . Even IMAX digital just uses two 2k projectors, each projecting the whole image. I'm not sure why.

    I just saw that Sony has a system to project two 2k images simultaneously from a 4k projector for 3D movies. I'd like to see a movie on that. I think non-synchronous frames for the left and right eye is what bothers me most about the 3D movies I've seen.

  13. Re:This would affect most 3D displays, but not all on 3D Displays May Be Hazardous To Young Children · · Score: 2, Informative

    The aperture of the human pupil is quite small, so the difference in focusing between 20ft and infinity is probably negligible. (If you focus your eyes on something extremely far away and look at something 20ft away, it won't look very blurry) On screen that is closer to you, such as with the 3DS, this may be a bigger issue, but the small size of the screen may help.

  14. Re:They -buried- the reports? on 3D Displays May Be Hazardous To Young Children · · Score: 1

    I find that the workarounds needed to display 3D are more annoying that the 3D effect itself. Putting on polarized stereoscopic glasses to watch a 2D movie trailer has many of the visual annoyances that the 3D feature has.

    I would like a 8.5" by 11" screen at 300 DPI -> 2550x3300 That is about double the number of pixels as my 30" monitor. 24" would allow for a two page spread with some UI elements around it.

  16. Sub-pixel anti-aliasing improves text DPI on iPhone 4's "Retina Display" Claims Challenged · · Score: 1

    If fonts use sub-pixel anti-aliasing, they display at 318ppi in one direction and 954ppi in the other. That averages out to about 551ppi. And with an IPS display, anti-aliasing works better because the screen has a constant gamma across viewing angles.

    I consider Photoshop the de facto standard because nothing has come close to reproducing Photoshop's functionality. There are several parts of Photoshop that feel archaic, and I'd like to see fresh innovative competitors, but everything else so far is missing very important functionality... I haven't even seen anything that has all the major features of Photoshop 4.0 (released in 1996)

  19. Re:Why doesn't Adobe leave Apple? on Adobe Evangelist Lashes Out Over Apple's "Original Language" Policy · · Score: 1

    Pixelmator isn't even good competition for the Photoshop of several years ago. It is missing an important feature that was included in Photoshop 2.0 (1991): the pen tool. Both Pixelmator and GIMP are missing Adjustment layers, which came with Photoshop 4.0.

    I could go on and on.

    For features that both programs have, Pixelmator may indeed implement many of them better.

    I would love to see some competition for Photoshop, but for many uses, nothing is even close.

  20. Re:Looks like an enhanced Wiimote on Sony's PS3 Motion Controller Gets Demoed and Named · · Score: 1

    Why didn't Sony put an LED ball on the subcontroller? That would even allow for some simpler 2-player games to be played with just one set of controllers.

    The Wii MotionPlus adds a gyro to the Wiimote.

    If the camera being on the TV is a better way to do it, why didn't Nintendo do it that way? Maybe because they would have needed a gyroscope from the beginning for pointing without the sensor bar.

    When using the Move for pointing, does the left to right axis drift out of calibration? Do they use a compass to keep it calibrated?

    Can you give some more constructive criticism, and tell me what I said wrong?  Otherwise, your post is worthless.

  23. Re:More precise? on How Sony and Microsoft Hope To Crack the Motion Control Market · · Score: 1, Interesting

    The main difference between the controllers is the position of the camera.  The Wii camera is inside the remote, with the target above or below the monitor.  The PS3 camera is by the monitor, with the target on the controller.

    The Wii configuration is better for games that have you point at the screen, and the Move configuration is better when you're not pointing at the screen.

  25. Gravity Gun is better! on Star Wars: the Force Unleashed Demo Sets Xbox Download Record · · Score: 3, Insightful

    I'm not much of a console gamer (I tried it on my brother's XBox). The Gravity gun in Half-Life 2 is so much easier and more gratifying to use than the Force move powers. The third person perspective in SW:FU makes it hard to select an object quickly. Both control sticks are used to move objects, making it feel mechanical. When throwing an object, it moves from the character's point of view, so it is hard to aim. Maybe I just suck at using gamepads.
