The Disposable Computer 358

          Well... For most current computers, long takes as much space as int, 32 bits (or 64 bits for 64 bit CPUs). And for any individual variable, it'll take at least that amount of memory even if it's 1 bit bitfield (not sure if common x86 compilers by default pack variables to take less space if they can, though).

          So using anything else doesn't really gain you anything in space, but it may well hurt you in peformance (and code re-use).

          Bloat comes from copy-paste coding, and slowness comes from incorrectly chosen data structures and algorithms. This all arises from poor design, so for example the programmer is often faced with decision to change entire existing code to make some piece of it more generic, or copy-pasting that piece and modifying it a bit to fill the new need.

            [S]lowness comes from incorrectly chosen data structures and algorithms.

            It is certainly true that a bad algorithm can result in slow code, but most of the difficult performance problems I've had to tackle in the last several years are more closely related with bloat. In other words: virtual memory thrashing.

            Data structures are often suspect when thrashing is a problem. If nodes are scattered far and wide, then the page file can get a workout. Powerful, dynamic containers often have high-overhead per node and make little if any effort to improve locality of references. More than once I've had to replace an STL map with a hash table in order to get decent performance. (I don't intend that as a blanket condemnation of STL, it's probably just a funky implementation.)

            But it's not just data structures. Code bloat in general increases working sets. The structure of code, with long chains of hooks in message passing and method invocation, can result in skipping through dozens of pages.

            When programs were simpler, smaller and more procedural, performance problems appeared inside loops. Number crunching is still this way.

            But today we have interactive, event-driven programs implemented with deep object hierarchies that mask how much code is actually being called. A single button click to bring up a dialog can trigger tens of thousands of lines of code scattered all across virtual memory. Branch prediction doesn't help here. Level 1 caches don't help. Pipelines are stalled. The processor waits for the VM manager to deliver the next instruction to RAM. With hardly a loop in sight.

            We have few tools to fight this type of performance problem. You can get more RAM or use less memory. You can try to improve the locality of your data structures and your code, but those efforts are often at odds with a lot of modern practices such as object-orientation, enhancement by derivation, and letting the VM manager and the garbage collector worry about it.

            Hardware has gotten inconceivably faster, but software has hardly picked up the pace (in most domains). Sure, the code does more today, but the factors still don't add up. And it can't totally be explained by a bunch of bad algorithm choices. Code bloat is a big problem.

            Fight code bloat.

          Speaking as a programmer whose first programming experience was Z80 assembly with 4K of RAM, I had to seriously revamp my thinking in recent years, but basically 32-bit processors work significantly better with 32-bit values. Also, except when memory is statically allocated and you've forced the compiler to pack memory allocated to your variables, that carefully considered allocation of a single byte is going to take up 32 bits of actual memory anyway, because once again, the CPU can access it that way significantly faster.

          In a nutshell, if you use a byte, short, or int, you're slowing down the machine. The only good reason to optimize to that level is when you're expecting memory problems, and as your professor pointed out, that is rarely a consideration these days (especially when you add modern paging techniques to the vast amounts of available physical memory).

          The more interesting question is the chicken-and-egg angle on runtime bloat -- did RAM increase because users needed it to run steadily ballooning applications, or did applications get bloated because cheap-as-dirt RAM meant end user machines had memory to spare? (I suppose both are probably true... which would be a bizarre conclusion if we were actually talking about chickens and eggs...)

        That may well be, but it's still perhaps one of the smartest moves apple ever made. While the rest of the computing world focused on standardized components, interchangeable io cards and memory, replaceable drives etc... Apple made an all-in-one system whose only interesting upgrade path was a new machine from Apple.

        And so, those who valued a complete, tested, supported system went with Apple, and that was the basis for (one of?) the most successful hardware companies ever.

        Yes, it certainly was. The Mac was not Apple's first computer with a mouse and a graphical interface. That was the Lisa, which nobody bought, because it was too expensive. A colour Mac would have required a huge frame buffer in order to provide adequate resolution. The memory costs of this would have pushed the price too high. Also, the 7MHz CPU was not fast enough to draw text and windows on a colour graphics display (again, unless the resolution was too small to be useful).

        And keep in mind that the Lisa, despite its immense cost, was also black and white. So was the Xerox Star (another failed GUI computer that cost too much).

        The Mac was not the first personal computer with a GUI. It was the first GUI computer that was cheap enough for ordinary people to buy. The hardware limitations you mention were necessary to keep the cost down.

    It Had To Happen: The Disposable Computer
    March 4, 2004 (11:40 a.m. EST)
    By W. David Gardner, TechWeb News

    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.

    "Initially, it will be used in industrial-specific applications as an enhanced and secure RFID device," said Cypak marketing director Strina Ehrensvard in an email. "Today, in pharmaceutical and courier packaging as a data-collection device; tomorrow maybe for interactive books, lotteries, passports, and voting cards."

    With just 32 Kbytes of memory, the paperboard computer's functionality is somewhat limited at present, but the firm believes its future will be broad. Cypak has entered into an agreement in the U.S. with MeadWestvaco Healthcare Packaging, which has marketing rights to the product and technology in the Americas.

    Ehrensvard said the device is currently in use in a trial sponsored by a Swedish university involving compliance monitoring of pharmaceutical packaging. The trial tracks when a medicine tablet has been taken out of a package; it is then placed on a Cypak scanner connected to a PC on which the information can be viewed and stored. Ehrensvard said the paperboard computer is being considered in another healthcare application, as well: doctors would use it to help authenticate the administration of pharmaceuticals.

    The Cypak product utilizes RFID technology that is based on printable sensors and electronic modules. The components are integrated on a variety of products, ranging from packaging and plastic cards to adhesives. In healthcare applications, Cypak says the paperboard computer time-stamps medicine dosages, which can be integrated with a patient's electronic diary. It can deliver sound reminders, too.

    Cypak has also developed a companion device--a smart card with an integrated numerical keypad. The firm expects this to be used initially in applications demanding high security. By entering a unique PIN on a card, a user can connect to the Internet and exchange data. Cypak says the card's encryption can't be copied or broken, enabling it to deliver "military-class security."

    "The paperboard computer concept and the PIN-on-Card are the same core technology--components integrated in different products," Ehrensvard said. "They exchange information to a PC with the same reader."

    Cypak offers the components on an OEM basis for about $1 each. The firm added that OEM components for its readers are available for approximately the same price in large volumes.

    The firm has developed a tamper-proof package technology with the Swedish Postal Service. Called SecurePak, the packaging technology stores sender and receiver relevant data and alerts receivers of any possible package tampering before the package is opened.

    Cypak will demo the products at the CeBIT 2004 exposition, in Hannover, Germany, later this month.

    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 ;)

      These days, relatively high-level CAD functions can be done with a $599 el-cheepo machine (I still wonder why some 3DLabs cards cost $1K).

    Theres some intersting specs [cypak.com] about its S2C chip on the Cypak website:
    8-bit microprocessor

    32kBytes non-volatile FLASH memory with >10 years of data retention.
    2kBytes Static RAM
    It also mentions using 128bit AES encryption, with RSA under development.

    ...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).

    However, it's right up there for the applications they outline - pharmecutical inventory tracking where a vial of drugs can cost a couple of grand.

    with Slashdot when 95% of Score:5 comments to such an interesting article are "Funny." 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.

    Come on guys. This is just a smart card chip with some sensors put on it. It has a non-ISO 14443 type A or type B interface, which means you can only use the readers provided by Cypak.

    On top of that it only uses AES encryption. Great. 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)?

    And 1 dollar per CPU is very good value I suppose.
