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.
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 ;)
Been there, done that, paid for the T-shirt
and didn't get it
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.
These guys don't need no stinking 32K. They work with only 4K.
"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.

Makes 32k sound postively roomy!
...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).

A few months ago I pulled out my old TRS-80 and the classic "Dungeons of Daggorath" (you pups have no idea what you're missing). It certainly struck me hard that in the instruction manual it specifically states that your system must have AT LEAST 5K of memory to play the game. Mad respect to all the trailblazers who managed to write kick-ass games under those restrictions.

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.

Yeah, i know what your talking about, i'm in a programming principles class at uni and i was quite pissed off when he said theres no reason to use byte, short or int anymore since all machines have memory to spare we should store every variable as a long.
I think this attitude is whats causing much of the bloat situation now days.
