Simple Computation Using Dominos
An anonymous reader writes "When silicon fails to beat Moores law, maybe dominos can help. This guy has created a half adder in dominos as a proof of concept for domino computation. If he intends to make a full domino computer he's going to need an awful lot of dominos."
I was going to say "Yea but does it run Linux?", but I thought I could avoid the resulting -1 Redundant mod down to hell by saying "Yea, but are there Vista drivers for it?" instead.
I hate printers.
A turing version of conway's game of life. But on reflection, if the "dominos" were something like charged nanotubes, then the creation of computing structures could be "grown" in a much different way then current cpu's, kind of think that's neat.

Apparently the server uses dominoes...
This really isn't such an interesting story at all. There is, in fact, a type of CMOS logic called Domino Logic. So nothing really suprising then.
Hey, guys. Big gulps, huh? Cool. All right! Well, see ya later.
Nonesense, they're perfectly reusable! You only need to watch out for a metastability period* of 10 minutes between clocks.
* To reset the dominos, of course.

No matter how fast he could ever make, rebooting is gonna be one PITA!

If servers were dominoes, slashdot must be that big and slightly smelly kid who kicks down all your hard work just as you're about to show it off.
I wonder if there's a way to do self standing dominos.
How we know is more important than what we know.
The site might be down, but the videos are on YouTubte
inputs = 0 & 1
inputs = 1 & 0
inputs = 1 & 1
... Domino Viagra ...
"In Soviet Russia, *you* fall over" In Soviet Russia, *you* are the domino, and you pushed over by the state in giant cold war social computer! Domino, the new Cog :-P

I didn't realize that Notes servers use real Dominoes, it explains their awful performance and quirkiness.
The preferred solution is to not have a problem.
Perhaps some kind of an electromagnetic surface could be used, with one end of each domino having some iron embedded... After the dominoes have toppled, hit a switch that turns on a magnet that pulls them into little slots which turns them upright.

I'm afraid this will open up a half-adder gap with the Deep South. In Alabama, it's illegal to play dominoes on Sunday. (www.dumblaws.com)
This kinda reminds me of Quantum Dot Cellular Automata. multivalence compounds are arranged like dominos and one of the "electrons" at one of the ends is shifted to represent the zero or one state and then the electron repulsion forces in the molecules propegate down the chain like dominos acting like adders whathave you. http://www.nd.edu/~qcahome/ -ian
Watch the 1+1 video, and you'll see that the stacked dominoes are actually glued together! No fair!
Details: His right hand pushes over a domino chain which knocks out a link needed to complete the left-hand output. But in order to reach the chain for the left-hand output, he crosses the chain for the right-hand output, which then has a gap. This gap is bridged by GLUING a yellow domino on top of a red one, on top of a blue one.
Don't trust anyone under thirty.
Of course, we've been using domino logic for a long time.
Lacking <sarcasm> tags,
You could do something similar to the Guess Who game to make it easier to reset. Go from 10 minutes down to seconds.....but save that for version 2....no sense trying to jump Moore's law.

I thought most computers (or the people who run them anyway) ran on Dominoes, Pizza Hut ... (insert your country's major delivery pizza chain here)

unfortunatly, i have a mac mini aka 4 shaders.. but this screensaver lets you use the video card to do it, so i imagine it's fun to look at.
:grin:
I just did a search, i didn't find anything about the largest. FWIW i'd LOVE to see the turing version in this screensaver

o0t!
Like twice as many more? Or does 1/2 adder + 1/2 adder != 1 full adder?
At least he didn't make a death adder.
Don't forget Poland.
God spoke to me.
In computer science study (3rd semester) We have learned that the 2-dimensional infinite domino problem is indecidable
this is because for any turing machine you can design dominos such that you can legally cover the infinite 2-dimensional plane if and only if the turing machine terminates...
so this is nothing new - I guess... I didn't RTFA, but what I read sounds exactly like that...
The MAFIAA is a bunch of mindless jerks who will be the first up against the wall when the revolution comes
welcome our new Domino overlords.
okay, after I saw it as a (not slashdotted *g*) video on youtube, i have to say: this has absolutely nothing to do with what I was talking about...
The MAFIAA is a bunch of mindless jerks who will be the first up against the wall when the revolution comes
out of dominoes. That is, if I give you a sliding-block puzzle, where the blocks are all dominoes laid flat in a box, and to goal is to slide one a certain way, that puzzle is a kind of nondeterministic computer.

I also think it's funny when Joe
Feel free to mod me down, but this applies to me just as much as you

Well, if you've watched the videos, you'd have seen that your points (1) and (2) have no merit, except for very small values of "shitload".
I suffer from attention surplus disorder.
A while ago I started with the physical implementation of a brainfuck machine http://en.wikipedia.org/wiki/Brainfuck. A mechanical brainfucker is actually not too hard to do if you compile the BF into the right patterns first.
Engineering is the art of compromise.
IBM actually did some research into using what amounted to molecular dominos for computing. It worked pretty fast, but they literally had to set it up on molecule at a time, and you thought dominos were a pain. They too predict that it might replace transistors. Read more about it here.
What is the big deal, it is only a half-adder. Not even a full one.
...someone will be using Tinkertoys. :-)
Dominoes, a new technology?
Next thing you know, IBM will have a Domino Server.
Have you read my journal today?
So, you're saying it's a Domino server?
I assume that Dominos aren't (and will never be) turing complete...?
I mean, each domino can fall over only once. So while you can do an adder, I'm not sure you could really get a for loop going.
I Know this isn't directly on topic, but for the gazillionth time I get to an article a few hours after it makes Slashdot, and surprise surprise the link is dead because of the Slashdot Effect. I really feel its time slashdot stopped mindlessly killing people's webservers with sheer wight of traffic - if its clearly a small website, why not mirror it?

...good old-fashioned silicon, not a briefcase substrate like this guy does. And like silicon, you can dope a briefcase too!
Great! But is only does one FLOP!
My server already runs Domino, why is he re-implementing this?

If we're going to replace our PCs with Dominoes would we replace our Macs with Pizza Expresses?
(Sorry, not very funny but nobody else had said it)
i think that the problem with them would be the huge energy losses... dominoes have stored energy, and weebles do not.
