has anyone done a compare between Mikaelh and Sunny's source code? That may give you the best hints as to whether it's good or not. I may be kicking myself if it's too good to be true, but I've already gotten what i had in 4 days in the past hour. Though that may just be odd luck since I've only had 6 blocks, and 3 on his client.

No blocks in 2 days (v12), then 3 blocks in last 5 hours (0.1.1).

Any1 who understands from code checked it? account at sourceforge.ne created 2 hours ago.
here is something I read on reddit that scared me:
"Well without too much technicality, the custom miners can steal your wallet.dat which stores your Prime Coins, addresses, and private keys. Along with that, they can change the code to give you a higher, false PPS rate leaving you to believe that it works better but in the end, it's only mining for the creator.
So what most people suggest is running the custom miner in a VM for sometime and see what happens. If all goes smooth and nothing bad happens, it's probably safe to run it on your actual OS, not the VM. Another thing that is recommended is to always read the code (i.e. on github) to see if there's something fishy. You don't have to understand all of it, but if you think something is fishy then don't use it. "

Where did all the blocks go 
?
Seems like difficulty went up. I have 20 servers, they had near block per hour, and last several hours nothing?How much u pay for server a day? Did you get profit?

is the expansion of collective knowledge enough?
No.Any number of examples can be given where "expansion of collective knowledge" is a useless endeavor of no arguable benefit to either the individual nor mankind as a whole.
Please play again.
I.e., narrow the scope of your statement sufficiently and I might even agree with you.
Finding sufficiently large prime cunningham chains can be directly used in security to make effectively impossible to brute force encryption happen, until someone figures out a way to find prime factors of gargantuan numbers easily, finding larger primes means the ability to make more secure and robust encryption under the current popular encryption schema.

does anybody know how to find the total hashrate (primerate)?
July 13, 2013, 05:33:48 PM
Code:
getdifficulty
7.98816758
Just about to 8. Remember that we're on a wacky logarithmic approximately base-30 scale for difficulty, so difficulty 8 is 30x harder to find a block as compared to difficulty 7.
My i5 failed to spit out anything for +72 hrs. I guess I have to check once a week from now on.

There are probably an infinite number of primes. Really, how scientifically useful is this endeavor?
There are definitely an infinite number of primes. Given a set of primes, you can easily show that there must be one more prime, and so on.
This project is not about finding new primes, because new ones are too big to verify in any sensible time for a block interval.
What does "scientifically useful" mean, anyway? Is something useful only because it makes money (ahem) or is the expansion of collective knowledge enough?
BTW, if you use encryption such as https, you are using the results of prime number math.
And Bitcoin's private key system is based around primes.

Seems like difficulty went up. I have 20 servers, they had near block per hour, and last several hours nothing?This seems to be working well as a demonstration of the value of a continuously adjustable difficulty.
It was 7.96 26 hours ago according to my console ... it hasn't taken that much of a jump ... 7.96 to 8 on a log scale is still only about
Edit: forgot base was around 30, math corrected.

Difficulty hasnt changed much I think. It was 7.988 just now, and 7.978 just over 12 hours ago. 1 block is now being mined every few seconds.
Then one block is still being mined every few seconds. It is just a question of how distributed is the set of people receiving those blocks.One of my comments on the previous page is relevant.
-- edit
As is the clearly evident attempt at market manipulation in progress on the Vircurex exchange. (I'm not watching the other exchanges, but assume that equivalent games are in progress there, also.)

That's very disconcerting ... though in the past four days of mining I haven't seen any primecoin between 5 cpus, when it seems some people have gotten as much as 100 on individual units. I hope nothing broke.

Pretty convinced that GPU/CUDA is the name of the game soon (or already if someone has figured it out). CPU for a single server, even quad Xeon tops out around maybe 8k PPS. Theoretically a single SLI NVidia setup could yield several MILLION PPS without breaking a sweat.
