Rubik's Cube Now Solvable in 20 Moves
A few years ago we reported that it had been proven that Rubik's Cubes could be solved in 23 moves. Well now that number is
down to just 20. Proving it required 35 years of computer time donated by Google to get it done.
Yes, you're right, we should devote all our time to getting ourselves to live longer, and none of our time to making our lives more interesting and enjoyable. That'll make a lovely world, won't it.
How about measuring that in actual computer usage? X MHz on Y cores per Z nodes over A hours? Or at least say it would have taken one X MHz processor 35 years to compute it. Computer-hours are nothing line man-hours or horse-power. At least those have good limits to their vagueness. Computer-time might as well be arthropod-lengths (are we talking dust mites or ancient giant sea-scorpions?).
They give the distance and number of positions for the cube here: http://www.cube20.org/ What I don't understand is why they have only approximate number 20 moves - from the article on the link above I understand that they solved all of the 20-moves combinations so they must know the exact number of those combinations

Thank God! And cancer? Still unsolved. I'll bet computer time could be used for that too. (sorry, bullsh*t like this hits very close to home for me recently. Nothing like having people dying, and then hearing how we are using resources for utter crap)
I don't think the limiting factor in cancer research is lack of computer time. If it were something so simple, getting the resources wouldn't be a problem.
Your raging is pointless.

That's what the lifestyle police are pushing for.
Eat food that tastes like cardboard, run like rabbits, and take pills based on how long they'll help you live (never mind quality of life - e.g. so hormone therapy for women is out - can't have 1 more heart attack per hundered even if it makes life bearable for the other 99) and you'll live longer or at least it will feel like it.
Just because it CAN be done, doesn't mean it should!

I agree completely. After watching so many people "live" well past their prime I'd much rather have a good life and a fast death.

Guess you should be using your spare cycles to help cure cancer. Lead by example instead of using your resources for the utter crap that is posting on slashdot!
Sometimes they like to be told what to do.
This only applies in the bedroom.
In all other circumstances they prefer to be the one telling you what to do.
As far as I can tell, by simply redefining "solved" any state should be reachable from any other in 20. There's nothing particularly special about all the colours being on the same sides.
1) start from any scrambled state, call it "solved"
2) scramble the cube
3) "solve" in 20 moves.

I don't think any of them cared that I did it one hand vs two hands...they just cared that I did it quickly. Being able to unhook a bra while having the other hand free to do...uh...other things was nice though :)
Of course, the danger of trying to do it with one hand was if you screwed up or if they had a really wonky bra, suddenly you had to bring your other hand into the equation. That was impossible to do without looking like a moron. If you already started with two hands, that's fine...but if you started with one and ended with two, that meant you thought you were cooler than you actually were -_-;;
