The Disposable Computer

sp00 writes "A disposable paperboard computer has been developed and is already in use in Sweden. Developed by Cypak AB, the paperboard computer can collect, process, and exchange several pages of encrypted data, the company says." Pretty impressive, given that they say it has a mere 32K of memory.

  4. 32k is more than I dreamed of a few (25) years ago by rcpitt · · Score: 5, Interesting
    32K is a lot of RAM. It's enough to do a fairly useful voice recognition system, or word processor, or even spreadsheet.

    I know - because that's how much RAM my Radio Shack Model 1 had after I'd purchased the add-on module and populated it with the extra 16K of RAM (the main module could only handle 16K) and before I pushed the limits by moving to 48K.

    Note that the module plus 32K extra RAM (to bring the system to 48K) was about $2,000 Canadian at the time.

    This is not insignificant - at least not if you've ever used something other than Windoze ;)

  5. Is it allowed to call itself a "computer"? by LostCluster · · Score: 4, Interesting

    There are devices marketed as calculators that have more than 32k of memory these days...

    High-end wristwatches are starting to behave like low-powered computers with a small black and white pixel-based display, the beeping speaker, and ability to accept wireless input. We're not calling those computers, just "smart watches".

    So, this really is more about "smart paper"... paper with a few chips in it and therefore the ability to beep. Only a small upgrade over the musical greeting card. :)

      back in the 1940s, a "computer" was a young woman who sat in front of an adding machine punching in numbers. It was actually quite awhile before the electronic machines came to be known as 'computers'. I'm sure many early designers would laugh at the thought of their complicated multi-ton kilowatt consuming monstrosities being named after the job a 19 year old girl did.

      What it is called depends on its use. You don't call a PDA a computer do you? Even though it clearly is one.

      If this device is in fact used for computing, then it is in fact, a computer.

    "Who would ever want more than 16K?" He said it to Woz when Woz was designing the Apple II. Woz wanted to put socketing for 16, 32 or 48K on the motherboard, as opposed to the 16K limit of the Apple I. Jobs was also against the color capabilities. Woz built them in anyway.

    When Jobs hoisted the pirate flag and built the Mac, he specifically left out expandability and color on purpose. It wasn't because of technical considerations, as the Apple IIgs was in design at the same time as the Mac. It was computer design by temper tantrum.

    ...the paperboard computer can collect, process, and exchange several pages of encrypted data, the company says.

    What do they mean by process? It sounds more like data storage. This is quite different than a computer. What kind of calculations (or computations) can it do?

    All of the examples could easily be implemented on this paper computer with nothing more than a clever encoding scheme and be decoded by a real electronic computer (PDA) with a scanner.

    In short this sound like a new type of ticker tape. The PDA and scanner would be the "Turing machine" (or processor).

    It really depends on what you do. Of course for Internet, word processing, etc, el Cheapo is fine. Even for Photoshop, Flash, and most coding, it's fine.

    For CAD you might get by. I've got no experience with CAD software. But for 3d modelling and rendering, the state of the art truly still isn't fast enough. A fast graphics card is necessary for showing the textured model on the fly. The better the card, the better this model, the easier it is to work on and see how it'll look compared to the real thing. The better the processor, the faster the render, the less time you have to wait to see the final product (and for a high-quality complex render, that wait is a pretty long time).

    It's good that people are catching on that they don't need the fastest machine anymore for pretty much anything. But there are still a few specialized tasks for which you do.

That having been said, I believe that our community as a whole (id est Slashdot at large) seems to completely lack any professionalism regarding cryptography by writing on the front page that "the paperboard computer can collect, process, and exchange several pages of encrypted data, the company says." which is supposedly 'Pretty impressive, given that they say it has a mere 32K of memory.' Surprise: To "collect, process, and exchange several pages of encrypted data" you don't need million times more memory than said data! Film at 11! What will be "impressive" next? The fact that strong crypto can use only few cycles per byte on general purpose processor? Wow! How impressive! Really? I don't need 4GHz Pentium 5 with 4GB of RAM to "collect, process, and exchange several pages of encrypted data"?

    Give me a break! This article is great news and really worth reading, but for much more important reasons than those that kids today think that you need ten hundred megabytes of ram to encrypt and store ten kilobytes of plain text. I, for one, feel insulted by such article summaries, because everyone who knows that I am a Slashdot user might think that I must be completely incompetent looking at the front page.

    I might only suggest for everyone who wishes to post stories about cryptography to read at least Applied Cryptography by Bruce Schneier first. This is the absolute minimum if you don't want to make an idiot out of yourself. Why cannot we talk about the serious implications of using RFID technology to build this machine instead of posting completely unintelligent jokes in the lines of "Imagine a beowulf cluster of those! It might have 640kB of RAM! Who needs more?" This is stupid at best and insulting at worst. I urge you to start posting insightful, informative or at least interesting posts before it is too late and this discussion is already archived.

    What I am personally most concerned about is how disposable are the active and passive (semi-)conductor elements which are printed on this boards. Does anyone have any experience in disposing them? It is not very clear in the article.

Most smartcard processors can do any symetric cryptography and DSA and RSA as well. 156 / 1024 bit 3DES/RSA is common nowadays and higher asymetric encryption is on the horizon, if not there. 16 bit processors are quite common as well, with 32 bit processors just around the corner. You can host web servers on smart cards for some time now.

    Obviously there are some interesting things to this story. What kind of wireless protocol will they use? How do they connect the sensors? What kind of sensors are available? What kind of operating system can be used? How easy is it to integrate it into some piece of clothing (eg)?
