I can't recite the residues, but I can generate them with one line in unix :grin:

To compute the first 10 residues in decimal, just run the following command.
[code]dc -e '0 3 5 7 11 13 17 19 23 29 31[dsa2r^1-sb4sclvxlcSdd0<uLdp]su[lcd*2-lb%scla1-dsa2<v]svlux'
[/code]The result:
[code]
0
0
0
1736
0
0
0
6107895
458738443
0[/code]If you're on windows, then you can do it in cygwin.

Anyone want to expand this to use a basic sieve to create the starting list of primes?

You verify the mersenne primes on your cell phone.

Maybe this is the record verification on a cell phone?

... you wonder whether you hold the world record for verifying a Mersenne prime on a cell phone.

where is the .jar file?

Not to point out the obvious, but...At the end of the link labeled "jar"? ...are you unable to download that link or something?

is two separate links rather than just a single link.

On my browser, post #629 is displayed with a line wraparound between [URL="http://resueltosya.com/llmidlet/LLMidlet.jad"][COLOR=#22229c]jad[/COLOR][/URL] and [URL="http://resueltosya.com/llmidlet/LLMidlet.jar"][COLOR=#22229c]jar[/COLOR][/URL], making it harder to notice that there would be a non-underlined space between the two.

when i download it i get a .zip file
once i renamed it to .jar it worked

You temporarily move your farm to the dining room and this happens.

I noticed the article said that it cooled the computer to a "new maximum of 84 Celsius"--that doesn't seem too impressive. On my slightly-overclocked Q6600, I usually get something between 50 and 65--never more than a degree or so above 65. And that's with nothing more than an air-based cooler that I picked up for less than $20. :smile:

Actual cooling performance aside, though, it is quite amazing that the machine actually worked, with all the crucial parts submersed in mineral oil. You have to wonder, though--would such a thing affect the computer's lifespan? If so, would it affect it adversely?

[quote=Anonymous;143743]Actual cooling performance aside, though, it is quite amazing that the machine actually worked, with all the crucial parts submersed in mineral oil.[/quote]Crucial properties of mineral oil are that it is electrically nonconductive and chemically nonreactive with the parts it contacts. (In water-cooled systems, the water _must_ be completely contained in plumbing and not allowed to directly contact any circuitry.)

Tom's Hardware did one with cooking oil (but that turns rancid after a while) a few years ago: [URL]http://www.tomshardware.com/reviews/strip-fans,1203.html[/URL].
