  1. Re:Yes, and maybe on The Rise and Fall of the Gopher Protocol (minnpost.com) · · Score: 5, Interesting

    It's true. I even remember Nicholas Negroponte, at a CHI conference in the late 1980s, giving a talk about the future of high-speed network connections to the home -- he mentioned that fiber could gives speeds of more than a Gb/s, and went on to make the case (with a completely straight face) that no individual could ever use that much bandwidth.

    I suppose I can't give myself too much credit for laughing at the time -- I was thinking of the bandwidth necessary to ship high-resolution images at video framerates, without giving a thought to compression. But even that long ago, I knew that anybody saying "we'll never need more than X" of a computational resource was setting himself up to look very silly in the future.

    It's just a shame that so much of the demand for bandwidth (and computational power) is driven by the videos and ads we don't want.

  3. "Pay today for what you'll use next year"? on Apple Said To Plan First Pro Laptop Overhaul in Four Years (bloomberg.com) · · Score: 3, Insightful

    Paying up front for capacity you'll need only later may make sense for a house, but not for a laptop.

    When I bought each of my Mac laptops, I knew I'd want to upgrade their memory eventually. In general, "maxing them out" would have entailed spending thousands of dollars for memory that I wouldn't need for another year or two -- at which point I'd be able to buy it from a third-party seller at a tenth of the cost. Same thing with storage.

    It's actually even worse than that -- for my first pro-level laptop (a G3 in 1999), the largest Apple-supplied memory configuration was 384MB, but third-party upgrades took it to 768. For my current daily driver (a last-of-the-line 17" MBP), Apple specs said its maximum RAM was 8GB, and that was all they'd sell you. I bought it from Apple's refurb store in 2012 or 2013, I think, when I saw that there would be no new 17-inch models. I immediately upgraded it from the stock 4GB to 16GB, at a total cost of something like $95 (I forgot to send in the $10 MIR). Buying an 8GB instead of a 4GB model would have increased the price by hundreds of dollars. And then there's storage -- I put up with the stock 500GB spinner for a couple of years, then popped in a 1TB SSD I got for under $300. When 4TB or 10TB SSDs are cost-effective, if I want one of those, it's another easy swap.

    The "just buy all the machine you'll need up front" approach is wasteful. You'll get more capacity and spend less money in total by starting with just enough, then upgrading. But if cost is no object, or you're solidly committed to just replacing your machine every year, knock yourself out. At least with Apple gear you get good resale value.

  4. What an OLED touch strip could be good for... on Apple Said To Plan First Pro Laptop Overhaul in Four Years (bloomberg.com) · · Score: 5, Interesting

    Wow. Are there really that many folks out there who touch-type with their function keys? I mean, I honestly don't know -- maybe there are, but I certainly haven't seen them.

    Think about how awful Apple's current scheme is, where fkeys are overloaded for brightness control, volume control, keyboard backlight control (really?), and whatever else.

    Now picture mapping those controls onto a touch-strip with a display. A small cluster of controls to the left (right, whatever), one for screen brightness, one for volume, one for keyboard backlight (again, whatever).

    Touch one, and a slider control expands out from it. Slide left to decrease, slide right to increase. Maybe, if extensive user testing supports it, "drag off the bottom" to commit your new setting or "drag off the top" to cancel it. Or maybe just lifting your finger commits it, and cancel isn't needed; we certainly don't get "cancel" with the current up/down key controls. Maybe touch detection only gives an x-axis value, but if I were sitting on Apple's patents, I'd certainly add at least a rudimentary y-axis measurement, and multi-touch detection.

    Double-tap (or "mash") the volume control to mute or unmute.

    Double-tap or mash screen brightness to blank or restore the screen.

    Don't want controls? Map a simple out-of-band gesture (again, drag-up or drag-down seems ideal) to move between fkeys, system functions, and application functions.

    I don't have any idea what Apple will actually do with this strip, but I hope it's less of a disappointment than their touch keyboard and multitouch stuff so far. I used the FingerWorks Touchstream keyboard for years, and I'm still bitter that Apple hasn't used more than 30% of the gestural technology they got when they bought out and shut down that company.

    If you're building a "web-based word processor" that can lose work because a client goes away, You're Doing It Wrong, so much so that responding to a low-battery signal is pointless. What if a router goes down? What if the user moves out of range of an access point, or cellular data?

    If Web developers (or the companies issuing their marching orders) wanted to respect my battery, they could start by ditching all the gratuitous animated ads, transitions, and whatnot. For bonus points, they could do it before my battery gets low, so that my battery doesn't get low in the first place.

  12. Yes, very quickly -- even more quickly than with other approaches, because your eye saccades really fast. (Although you probably don't have to render intermediate frames during the saccade, because IIRC your brain sort of ignores incoming detail during the movement itself.)

    The win is that you have to render a much smaller patch of high-resolution detail, which saves computation in some parts of the pipeline. You've still got to do all the intersection, bounding-pyramid, depth-sorting and whatnot for your whole model (I assume -- it's been close to thirty years since I've done much in 3D graphics), but you don't have to crank out as many pixels. To get "retina" resolution, you'd need a foveal patch no more than maybe 500 pixels in diameter, and the rest of the visual field could probably get by with another 500 pixels on a side. That's a lot less painting than the stack of 3840x2160 screens you'd need to fill the whole visual field at that resolution -- probably between one and two orders of magnitude smaller.

    As far as the rest of the pipeline, I guess you win because those rapid saccades don't significantly change the viewpoint (head location), so there won't be a lot of changes to object order or occlusion. (Your pupil does shift its position, since the eye's center of rotation is obviously near the center of the eyeball, but any virtual object that close to your eye ought to be blurred anyhow, unless you're playing the final levels of Quest for Nearsightedness.)
