  1. Not yet- on LHC Success! · · Score: 1

    Until it can create a blackhole and sucks the whole Earth in, I won't consider it as a real success.

  2. Re:One test they never run - FRAGMENTATION on Intel's First SSD Blows Doors Off Competition · · Score: 0

    Yes. Imagine the files are tightly packed, and if you try to growth the files in the middle...the file will get fragmented.

    I am pretty sure that The SSD is not read byte by byte, but chunk by chunk, like 4KB per read request, instead of reading one by one. So if files get fragmented, and needs extra read to get the file read, there are always overhead and waste.

    In short, we still need to defrag SSD-

  3. Re:Personal experience on Cell Phone For the Blind? · · Score: 1

    Being a geek with 20/20 eyesight, I also hate the fact that I couldn't dial without looking at my Dopod phone. (I would pass about the voice feedback, I don't like the idea of announcing who I am dialing to to the people around me, and my low usage of phone don't warrant me to buy a bluetooth handfree)

    Sometimes when I am going from indoor to outdoor and when it's sunny day, it's also a pity to have to turn the screen backlight to full before I could dial.

    I hope someday programmable tactile feedback would come. Imagine a transparent layer of whatever laying on top of the touch surface, and dots can raise and flatten pro grammatically. We don't need 320*240 resolutions of raising dot, just a few handy dots at strategy place would boost the user experience to sky.

  5. Finally why pay-as-you-go is good... on AT&T Slaps Family With a $19,370 Cell Phone Bill · · Score: 1

    I am glad that I am using Pay-as-you-go in China. Basically that's what the majority using. We still get plans with it - it deducts the subscribed amount of money from the prepaid card and we just refill it from time to time.

    Pros? No surprise like this! it's only limit to what I spend. I also get an SMS notification instantly when the stored value crosses my preset threshold.

    Although unlimited data plan cost ~USD60, but 25MB/Month at for only USD-1/Month is a pretty good deal, good enough for my PDA. Only EDGE though, no 3G yet.

    That's said, we only have 2 operators which basically they almost monopoly (or stereo-poly?) the market, may be that's why a non-lock in plan would work. But at least AT&T can have an SMS alert when the bill is shooting to the sky.

  6. Memory management? Let's the OS do it! on Chrome Vs. IE 8 · · Score: 2, Interesting

    Application is not a good place for handling tho memory, even if you manage to re-invent the wheel and write a very good memory allocation algorithm, application layer just does not have enough visibility to get a whole picture of everything.

    In short? Let's OS do it! Hey, OS is the expert and MM is exactly the job of the OS. It handles the fragmentation, the caching, the sharing of executable memory image. Chrome do exactly that, it just rely on the OS, sit and enjoy.

  9. Re:I'm surprised that consumers want them... on A Turning Point for Touch Screens, Says the NYT · · Score: 1

    Totally agree.

    I did one universe touch screen remote control as a school project. It's done by laying a Palm touchscreen on top of a Dot Matrix LCD. Although it looks cool and earn me a A+, but practically it inherits the same problem exactly like what you have describe - touch feedback.

    I hope some day someone could invent an touch interface with dynamic texture for touch, just like the dot on the F and J key. I imagine it could be done by micro-heater (like those used in inkjet) which heat up a small bubble under a membrane on the touch interface.

  10. Re:Slashdot in China on China Blocks iTunes · · Score: 4, Informative

    A government so concerned about loosing face in the Olympics...

    Precisely, it's not the government, but the officials are so concerned about that. Mao taught the people a lesson that they have to be "political correct" otherwise you will lose your head (most likely not only you but your family), that's 70's and has since become a culture. Today, you won't lose your head that easily (there's a lot of voices against the government in local blog and forum) but for the officials, there is nothing "wrong" to be "political correct", why risking my job in doing the otherwise?

    If you think we live under a government that the people fear, that's probably how an extreme Chinese might think about the American too (under the fear of terrorism and the watch of the Big Brother). The fact is, no we are not, and we are probably the same. Both China and US, the general public are not affected, we still work, play, shop and watching porn unaffected. We both think the government is stupid. There might be a little difference how we voice out about our hate to the government, but other than that, I think there are no difference. (Ok, I'm a Hong Kong citizen currently living and working in Shanghai, closely interactive with my colleagues who are Chinese. I also regularly travel to US for working purpose and has been an Exchange student there.)

    And, as always, the Chinese already figured out how to circumvent the particular iTunes problem, if you know how to read Chinese: http://www.macx.cn/a/a.mac?B=4000&ID=656667&Ar=656867&AUpflag=1&Ap=1&Aq=1

    Yes you are right that it use magnetic flux to transfer the energy, yet the efficiency over the air over long distance is so low that just enough to power the cards and gadgets like mouse. 60W over 2 feet is impossible with that and clearly the technology posted here today is not the same as those you found around your home now.

    I mean the powering methodology would be similar to the touch-mode credit card, e-passport, train payment system (the London one mention in a week ago?)...They are done by induction. It's basically same old technology that we have been using in AC Transformer, without the iron core and the power efficiency is real low, yet enough to power the chip on the card.

    If you have one of those card, shine a light behind it and you will see the coil around the card.

    That mouse is just how RFID, or the touchless payment cards work. However, the technology presented here is talking about a totally different mechanism.

    FTA: "Induction is already used to recharge electric toothbrushes, but that approach is limited by the need for the toothbrush to be placed in the base station."

    If you try anything like transmitting 120W (60W / 50% efficiency) in that old way, mostly will end up with a mini-induction cooker

  16. Re:Wireless USB? Huh? on Hands-on Look At USB 3.0, Spec Details Revealed · · Score: 2, Insightful

    WiFi is a general networking thing, and USB remains to be a point to point between host and one devices thing. Use is also device protocol (use of system drivers allow much greater user experience easier), instead of being just a data transmission protocol as in Wifi.
    The software (and the user interface design) is much simpler with that...

    Like those nasty DHCP, DNS and related failure/exception cases are out of picture. Encryption is also much easier/cleaner to design because the data are never flow between devices.

    WUSB is pretty much the same as Bluetooth, just much faster.

    while there are not many type of devices that I can think of could make use of 480Mbps without a power adapter, but think of bluetooth which is dead slow, I would love to have my PDA and Camera sync to the desktop over WUSB.

    OpenID does not required the use of password as the way for human to authentication oneself to the system.

    It's just up to the OpenID signatory to use whatever technology to authenticate someone. This human interface is decoupled with the underlying authentication.

    Although most public signatory currently use username+password, but it could be change. Say you could implement your own, using PKI to recognize your own certificate stored on removable media. If you gone crazy enough, nothing stop you from implementing One-time password + Biometric + whatever-you-can-think-of to authenticate yourself to your own signatory.
