A Linux Machine For Your Collar 318

MadSaxon writes " has a brief but titillating description of a very small Linux machine based on the PXA255: 20 x 80 mm, '64MB SDRAM, 4MB Flash, MMC/SD/SDIO slot, and power management. It takes 3.6V - 5.0V power, and has been drawing under 200 mA.' It weighs less than 12g sans battery, and 'can fit in a collar undetected.' Is collar-top computing the Next Big Thing?"

    It has always struck me that putting more and more power close to people is the wrong way to go. Instead, why not make these machines effectively a "dumb terminal" and hook it in the Internet through a wireless connection, where it would interact with web services? Then, you can have a supercomputer on your side, and you wouldn't even know it.

    But, I guess that goes against the post. My other thought is the social stigma associated with these things. I still get people telling me in an embarassed tone of voice that they can't remember my number any more without their cell phone handy. I see these things being huge in the area of 'intelligence augmentation' and 'external memories', if only people could accept that learning things rote is no longer something we actually have to do any more.

    • It has SDIO. What more do you want? Stick a 802.11 or bluetooth card in there and your ready to go.

      You're exactly right, that is the way things are headed. But stop to think about the local computing power that may be required. Things like sophisticated video compression algorithms, speech recognition, and in the future perhaps an intelligent agent which sifts through data and presents useful items (think advanced version of dashboard). All of these things will need power close to the cpu. After that, Sun had it right, "The Network is the Computer". Especially for storage of data, etc. But there will always be a baseline requirement for local computing power.

      Also, another idea to consider. By offloading processing power... ie, the "dumb terminal" approach, you take away the power to customize your experience. You effectively end up with an advertising receiver. You'll be powerless to access the types of information that you're interested in, and the device becomes more like a television, only capable of doing what it's preprogrammed to. Most people will not go to the effort to set up their own web services to connect to.

      Distributed processing power is the future. But with lots of power spread out over millions of portable devices all interconnected, it becomes more of a social appliance that a number crunching system.

      (I drift off topic...)

      Personally what I'm most interested in are assistive agents. I think in the future you may be considered handicapped to NOT have one of these things someone on your person allowing you to tap into the global network, maybe even subconciously. Think instant google searches based on something you're thinking about, augmenting your memory automatically. Some really cool stuff, just hope the economy keeps together so I see it happen in my lifetime.

    Ok great the computer fits under my collar, but does it have a jack to plug right into my brain? Or must I wear those uber-geeky display glasses with a one handed keyboard to use it, which would seem to defeat the purpose of yet another ultra small computer.
