RC5-72 Clients Available on distributed.net
Yoda2 writes "From the distributed.net site... 'The RC5-72 project is now officially up and running, as of 03-Dec-2002! You will need to download a new client in order to participate. Our FAQ-O-matic has been updated with the beginnings of a new RC5-72 section.' Also, there is a $10,000 prize for the winner, but as with the other RC5 projects, the owner of the computer that finds the key does not get all of the money."
That it will take 3 years, 2 months, 12 days, 4 hours, 17 minutes and 10 seconds to crack it.
11 seconds.
It's an outdated, unused cipher with a completely unused keysize. Do something useful, like protein folding or golomb rulers. (Not SETI@Home, I said useful ;-)
if they randomly cracked it in a week?
We KNOW it'll take a lot of computers a long time to crack the code.
These cycles would be a lot better spent on something constructive like the protean folding project.
It's Christmas everyday with BitTorrent.
the current stats page doesn't seem to be linked from the main page anywhere... anyway, here's the link.

RC5-64 took 4 years, and this has a keyspace that's 256 times larger. Even if we assume that computers are 4 times faster now than the average speed at which RC5-64 keys were processed, we're still looking at 256 years to completion. It doesn't seem like it makes any sense to start until computers are at least 20 times faster.
How to solve most of our problems: 1.Lots of nuclear plants. 2.Cure aging.

I'm torn as to wether or not I want to participate in this, or Folding@Home.
I ran the RC5-64 Project for a long time. I like it, In my year(s?) or participating I developed a habit of definding it, explaining it, and had grown to care for it.
But when the end of RC5-64 came along I was left idle. I believe that some good can come of these distributed projects, but I've never made the effort to install F@H on my assorted boxen, my own little garden.
I'm well versed in the cow though, and could be back on RC5 quickly...
argh, choices, choices.

Team Slashdot was 5th overall for RC5-64... maybe it's time to step it up a notch, except that there is no Slashdot.org team yet. :-/

Come on people -- why waste the incredable amount of processing time this is going to require. There are much better uses for cycles -- from cancer research to finding unique, undiscovered numbers (primes, etc.)
At some point, there's just no point...
But do you think the average computer will stay at this speed for the next 256 years? :)
Althogh that link does work, RC5-72 stats are not yet available, we're still working some bugs out.
There are so many other uses for CPU cycles than this. I've looked at the site, and none of the reasons they are doing this is really worth the massive amounts of electricity that go into this BS: an idle CPU uses a lot less than a busy one.
:-) I'll give them that.

- To do something with all this computing power
There are other interesting more useful things to do with computing power.
- To prove that small-bitsize encryption is insufficient
I think they got the message the first 2 times.
- To explore the feasibility of cooperative networked multiprocessing
You mean they're still not convinced after all those years?
- Because it's fun
Yeah, okay... I guess everyone has their little projects.
- Because you can win money!
Um... yeah... you can win money with the lottery too. This might give you a slightly higher chance, but you'll have to wait many years to find out if you've won or not.
- To get to know more people
You don't need to waste CPU cycles and electricity in this manner to meet people. Running an RC5 client is not necessary to use IRC.

Costyn.

Anyway, I think all of these efforts would benefit from some real competition. You can't believe how rewarding it was to race with distributed.net and the other efforts and to see who can develop best optimized code - for example.
But to build that spirit of competition (without doing duplicate work) between the efforts, we would need some fresh and new (reasonable, interesting) idea for: what to crunch? Any ideas there? I am sure the guys at distributed.net and the multiple other efforts would love to see the same "fighting spirit" again as well :) And as result, I believe everyones code will be optimized much faster and new ideas will be created faster, more people will be interested to join...but: what to crunch, what would be really really interesting? :)
it appears..the spoon ran away.
I'm a big retard who forgot to log out of Slashdot on Mike's computer! LOOK AT ME.
If it's a distributed solution, don't you also have to consider the sheer numbers of processors participating? There are more folks in participating in the project now than four years ago, and many of these folks have more computers.
Five years from now, it may be that your house is participating, your cars are, as well perhaps as your shirts and underwear.
In sixeen years, shortly before skynet takes over, the smart dust in your living room may decide to participate as well. (Most likely the dust will not participate, but will instead form themselves into a gollum and try to kill you, but maybe...)
Other then yet another encryption crack or useless mathematics, what else is there around to waste my server's cycles on? Preferably something useful, like cancer research or something. Oh, and SETI isn't considered to be useful IMHO.
Hate me!
Out of curiosity, what's is the justification for using all this computing power to crack some code? Personally, it seems even more futile than Seti@Home, but I'd like to hear from participants what their reasons are.

We can use some of distributed.net's power to spell check this guy's post!

opening the page in Chimera gave me bloated font size. Doesn't happen on any other pages. Is this a strange bug in Chimera? Slashcode? Anyone else have this problem?
I hereby place the above post in the public domain.
Why do I never have moderator points when I need them... Come on people, this parent is FUNNY.
OK, granted that this project may be a waste of computing power (assuming that they're not going to be just sitting there wasting cycles anyway), but I saw a lot of people suggesting that users instead participate in the folding@home project. That got me to thinking...
I'm not against folding@home, but I don't think that the number crunching approach to solving protein folding is ever really going to give us the breakthroughs we want. We need to theoretically address the issue of folding and find more simple behavioral theories with which to approach the problem. I know a lot of work is currently being done from the physics front with spin glasses and other complex systems models.
The difference between these two approaches is the difference between the current encryption cracking projects, and a Sneakers-like approach to actually find a mathematical solution to the large number factoring problem.

2^(t/1.5) = 256
(t/1.5) = log_2 (256) = 8
t = 8 * 1.5 = 12.

The principle of Optimum Slackitude points out that because of Moore's Law, the overall cost in time or money can be decreased by waiting to being. If current numbers predict 12 years to exhaust the keyspace, and we wait 18 months to start, then that first 18 months worth of effort will have to be made up at the end, but 12 years later computers will be 2^8 or 256 times faster. That first 18 months worth of effort will only take 2-3 days to make up at the end of the project.
I think that's probably what people object to about starting this project now instead of in a couple years.
As I think you know, you raise a valid question: the social good to society of the answers to these distributed processing questions (aliens-p, better drugs, better understanding of math) vs. the social good to society of better energy conservation.
And then you also bring in the economic problems of understanding altruism (folks do pay the costs of participating in these low payoff questions, why do they?).
The problem of free riders. Jeez Tim, when we find the aliens one hour too late, just because you didn't turn your computer on, I hope you're the first one up against the wall.
And even the problem of how much sense does common sense make: I think you want to look at average power prices, not peak.
http://www.aspenleaf.com/distributed/updates.html damn near exhaustive listing of distributed computing projects that is updated frequently. I personally run Find-a-Drug.com.
Its pretty much some useless thing that you run, and see if you can get more time put into it than others. Most people do it just to look at the Statistics and compare with everyone else out there.
ProgressQuest is worse and better at the same time. It does not eat up all your CPU cycles like d.net does, but it has no purpose what so ever.
Its not what it is, its something else.
RC5-56 took about 1 year iirc, and RC5-64 didn't take 256 years, not even 64 years if you divide by 4.
:)
But I still can't tell you if it's worth it.
Don't answer me. Moderate. Slashdot is about moderation, not discussion.
- Because you can win money!
Um... yeah... you can win money with the lottery too. This might give you a slightly higher chance, but you'll have to wait many years to find out if you've won or not.
I wonder how many lottery tickets one could buy with the money spent on electricity to power the cpu cycles? Enough for one or two a week, maybe? Given the potential payoff, the lottery might be a better choice, assuming you're only in it for the money.
Dude, you're all wrong....there is no spoon!
Moderation: +4. Modded 70% Funny and 30% Overrated. 100% Saturated.
Compared to this, I honestly believe that there is some point to distributed computing in cracking codes and doing useful things, like the Optimal Golumb Ruler finding, even when RC5 is a dead issue. There IS more to Distrubed.net than just cracking RC5
