  1. Re:Did the first Prius have this problem? on High Depreciation May Slow Electric Car Acceptance · · Score: 1

    The people who can afford a Prius, particularly when it was first released, can afford some depreciation.

  2. Re:Wait, that makes no sense on High Depreciation May Slow Electric Car Acceptance · · Score: 1

    Yes. The leasing scheme means you're paying against the depreciation of your vehicle/battery while you own it, and the guy you sell it to does the same, so there's less of a price drop when you sell the car to him. Neither one of you is gaining anything, rather you're both losing because you're not only paying for the battery you're paying interest as well.

  3. Re:Battery replacement on High Depreciation May Slow Electric Car Acceptance · · Score: 1

    If you stipulate that batteries are expensive and wear out quickly, it doesn't matter what you do - the value of a car that needs such a battery vs. a car that doesn't will either a) start out higher, b) drop faster, or c) have to be propped up by some sort of subscription.

    If you buy the battery outright at the beginning, as you do now, you're looking at a little of (a) and, as the article expects, probably some of (b). The suggestion to lease batteries converts this into (c). Your suggestion also converts to (c).

    As others have pointed out, a change in business plan doesn't solve the problem, it just moves it somewhere else.

  4. Re:Still doesn't bode well on Google Remotely Nukes Apps From Android Phones · · Score: 1

    I was under the impression you had to root most consumer Android phones to change the firmware on them. That's almost exactly what happens when you jailbreak an iPhone. Oh, and all indications are that jail breaking an iPhone does not void your warranty. I returned a jail broken iPod touch and it was replaced no problem.

    Apple hasn't really tried to block jail breakers, beyond fixing occasional vulnerabilities that they exploit, such as the original tiff-on-a-web-page jailbreak. They DO try to block people from unlocking, probably as required in their AT&T contract. I think the baseband is supposed to be off limits on Android too. Its certainly not part of the open source distribution.

    Yes. Visual acuity is empirically measured, not calculated by counting cones with a microscope.

  6. Re:FaceTime feature is rather scary on A Professional Perspective On Apple's Retina Display · · Score: 1

    I didn't think Apple would ever put a front facing camera in an iPhone for just that reason. It will be even worse in an iPad. And yet everyone is clamouring for one.

  7. Re:We knew this years ago ... on A Professional Perspective On Apple's Retina Display · · Score: 1

    Printers only really print effectively at about half their advertised resolution. So yes, 600 dpi as a big thing. 1200, not so much. 2400? Nobody cares.

    Several posters on Slashdot have done the math. That would be the equivalent of what, the homeless guy at the train station on the way to work?

  9. Re:B-b-b-but I thought Apple was a marketing compa on A Professional Perspective On Apple's Retina Display · · Score: 1

    Did you miss even reading the summary? A 300-and-a-bit dpi screen has pixels that are unresolvable by people with 20/20 vision at a normal working distance for a smartphone (which is similar to working distance for a sheet of letter size paper). That is, at normal distances, anything higher doesn't matter. That includes dithering effects or whatever (which are actually just blurring, decreasing the resolution).

    Also, anyone who has ever done any print work knows that a printer that says it does X dpi actually prints at effectively about X/2 dpi, due to a variety of things. So a 300 dpi printer produces an effective output at 150 dpi. I remember 600 and 720 dpi printers being a big deal. After that, nobody cared, despite the marketing quickly ramping it up. I think the last printer I bought said it does something like 1600 dpi, but it doesn't matter.

  10. Re:Apple is a design company on A Professional Perspective On Apple's Retina Display · · Score: 1

    Not physics (what would you use a physics PhD for in this area?) but Apple has employs an awful lot of engineers. Quite a few of them have expertise in things like silicon technology design and manufacturing.

    Did Apple invent high res displays? Of course not. Did they look through a catalog and pick this one out? Nope. You can bet someone at Apple decided they wanted this and some Apple engineers worked with their suppliers to get the thing made.

    Unless Macports supports Aqua now, don't do it.

    Rather:

    "Is there any python IDE with this built in... anything that mimics the 'desktop' of Matlab?"

    TextMate. If you're not on a Mac you have a choice of all the other Python editors, one of which must surely have those basic functions.

  13. Re:Does Not Work with Most IDEs! on Finance, Scientific Users Get ActivePython Updates · · Score: 1

    The funny thing is, anyone who can type "easy_install" on the command line doesn't really need Activestate's distribution and has been happily using Numpy, Scipy and Matlotlib for years.

    In some ways, ActivePython is like the VB of the Python world.

    True, although they tried it out publicly in OS X before announcing the iPhone.

  16. Re:Oh Please on Developers Expect iOS and MacOS To Merge · · Score: 1

    Sure, when Apple finds something works particularly well on the phone they implement it on the desktop, if appropriate. I'm having trouble thinking of a major example of that though.

    On the other hand, comparing IOS 4 to the first iPhone OS 2 API, quite a bit has wandered over to the iPhone. I noticed the Accelerate framework is in there now. If only they'd make PDFKit available.

  17. Re:Oh Please on Developers Expect iOS and MacOS To Merge · · Score: 1

    Let's see, they asked a bunch of IOS developers whether they thought their particular platform of choice was going to take over. Surprisingly, many said yes.

    This has always been an idiotic conspiracy theory and completely forgets that IOS is a cut down version of OS X. Same language, same classes except for a few UI ones. Are the two SDKs going to merge? They already are. IOS is slowly gaining more and more functionality ported over from OS X.

  19. Re:Calling it now on Adobe Flash Player 10.1 Arrives For Android · · Score: 2, Interesting

    You don't need a conspiracy theory to explain it.

    Apple got tired of Adobe screwing around with poorly performing Flash plugins for the Mac for so many years, not to mention screwing them over with 64-bit CS. When it came time for Apple to decide whether they wanted to let Adobe control one of the primary components of their new mobile OS they decided against it.

    I'm sure the profit motive from the app store helps, but Apple decided to not support Flash long before there was an app store.

    Most of the time. Not always. And the not always gets more common when you have a prime minister who likes to play procedural games. A lot of those procedural games require requesting that the governor general do something. And the GG CAN say screw off and get back to work.

    The point is you can't really compare it to an iPad and say it's cheaper. If all you want to do is read books then it's fair but the iPad is a general purpose device that is also a pretty good book reader. Of course it costs more.
