What does that even mean? If scientists predict with 99% certainty that a meteorite is going to hit your town, do you evacuate? Or do you listen to the one guy who says its all bullocks and the measurements are probably off, thats its a government ploy for whatever conspiracy?
I dont know about you, but Id pack my bags if they predict a 10% probability. Would you wait for 100% certainty? Ie, after it hit?

Scientists are almost never 100% sure of anything. Climate science is no exception. You wont find any respectable scientist claiming they are 100% sure. IIRC, the IPCC put the number at 99% or 99.5% certainty that our fossil fuel burning is causing climate change. So how does that relate to the above statement, that you think its more like 50%? Or 5%? Or that 0.5%=50% ? Or that we should just bet the planet on their estimated 0.5% chance they got it wrong? Wouldnt even a 50% chance be enough to take measures?

FWIW, your hero Lindzen will only bet 1-50 odds that he is right and the planet will be cooler in 20 years. That makes him more skeptical than the IPCC, but not by much!


That domain alone shows its cherry picking. Its a site that looks for evidence to support a (political?) point. Thats not how science works. ITs not how the IPCC works. What IPCC does is review *all* relevant scientific research, whether its from Lindzen or anyone else, and try to condense that in to a readable consensus view. That is not cherry picking, its quite the opposite. You can not put that against a site like the above and somehow claim they are equal.  You might as well contrast some religious nut's book on "creationism" and contrast it with 100 years of science and conclude we really do not know if evolution is real.

How is that somehow not cherry picking?

Since you do science yourself, you know how science works. It would break down if no scientists would oppose a consensus view and try to argue against it.  Thats entirely healthy, and so you will not hear me smear Lindzen for that. The point is he is one man casting vague doubts on the science, many of his arguments have been thoroughly refuted (which has admitted to):

The guy is a contrarian. Even if a smart one, he will try to argue anything. Thats good for science, but its not good to just dismiss the overwhelming body of evidence and take his word instead. FWIW, he also hardly believes in the link between lung cancer and smoking. Believe him on climate change at your own peril.

Why do you put experts between quotation marks?
And why is it somehow smart to blindly disbelieve what is the overwhelming consensus among the worlds best scientists and instead do your own cherry picking "research"?  Do you consider yourself such a wold authority on climate science that you know better than all the worlds scientists combined, that you think you can do a better syntheses of all the available science than the IPCC  ? I find that notion as ridiculous as thinking you would be able to build a better space shuttle than NASA in your garage. They are only "experts" after all, what do they know.

Ive never done any water cooling, but if you are worried about algae, you could use an UV-C bulb.  Its perfect to avoid green water.

PCIe extenders arrived yesterday and my "Michael Schumacher" oil radiator arrived this morning.
I should have read the specs more carefully, it clearly said 18.5cm so I only have myself to blame, but holding it in my hand, that is MUCH smaller than I thought by looking at the photograph.  Its exactly the size 2 90mm fans next to each other, so smaller (but thicker) than your typical highend PC watercooling radiator.  Somehow I pictured it at least twice that size.

Still, with its relative thickness and extremely fine grating and Im sure its more than capable of dissipating the heat of a few gpus, at least when submerged in cool water. Its actually kinda neat, and I cant believe how light it is. It came with a certificate of authenticity too, so thats at least an extra 100 MH/s .

I also picked up the cheapest 1200L/H aquarium pump I could find (15 euro). I dont expect it to last, Im sure it will overheat and fail,  I just want to see what happens regarding flow rate and temperatures when it must pump oil so I get a rough idea of sizing the actual pump. 1200 L/H turns out to be a serious amount of water for such a tiny pump, wow,  but then it doesnt have to cope with thicker oil yet, nor any resistance from long tubes and the radiator, so we'll see what that gives.

Now Im waiting for some epoxy raisin to arrive to coat the foam, I need to pick up some tubing and with some luck Ill have a test setup running this weekend, although it will be "dry" for now, cooling the oil with just fans. Its freezing -11C outside, so my pond pumps are shut down. Should the oil heat up too much (which I highly doubt) I can always submerge the radiator in a bucket of water for testing.

question: have any watercooling guys here measured water temperatures at the inlet and outlet of their radiator? Can you give me a ball park guestimate?

Seems like guiminer works better with 12.1 drivers than cgminer then.
FYI, my 5850 at 850/300 MHz gets a little over 350MH/s in cgminer with default settings. I am using catalyst 11.9.

Underclock your memory, as much as you can. If wont hurt performance (on the contrary actually) and it will lower temps a little bit. Even so those temps are uncomfortably high IMO.  Try to improve air flow in your case or speed up your fan. If your card supports it, you can also try reducing voltage.

cgminer 2.2 has a reworked API. Perhaps thats what you are struggling with?

Im not even sure what scoffing means, but I scoff at it:




As for stales, this makes me happy:

Almost 2000 shares this shift.
Rejected    0 (0.00%)    

Dont we have to flush our dns caches? Whats the new IP address, just to be sure

Wow. That was fast lol.
Very smooth so far!

There are endless discussions about that, so I wont get in to it. If you feel uncomfortable, wait and see.

~500 MH is just one good card. Why build an entire rig for that? Assuming you have adequate power supply, just plug a 5970 or something in your existing PC. Or if you insist on new, a 6970 or 7970. No need to pay anyone to do that and ship it.

I dont know what electricity prices are like in Greece, but if they are anything like most of Europe, you may want to look into FPGA mining instead. Have a look here:

They have yet to ship a board, but they are supposedly about to. Keep an eye on it.

So now you admit your OP explanation is untrue. AKA as a lie.
Why dont you edit the OP and say you have a secret business model you dont want to disclose instead of a describing a nonsensical one?

Freshly minted blocks take more than a day to mature. So he cant even use his newly mined blocks for what you describe. I could end there, but its more nonsensical than that;  assuming he could spend the new coins or delay PPS payments an extra day, hed get less than 1 day worth of bitcoins for 10-15% fees on the total amount.  It would also be far cheaper to lend the money at the bank and deposit the extra 1 day average turnover at Mt Gox.

But thats not even the biggest issue; the biggest issue is youd still have to do what he says is impossible or so hard in SA, or at least what the whole purpose of this set up is supposed to be:  avoiding exchanges to convert fiat in to BTCs.

So there is no logic in it whatsoever, it just doesnt add up.

Why waste all these words when a short reasonable clarification -not of any secret, but of what you already claimed will make me look like a fool?

But if you must know, I only think you are lying. Whatever your reasons, you are giving a nonsensical explanation in your first post. Anyone with a half a brain can see that, and you dont even seem to be denying it anymore, all you do is post and post while avoiding the key issue that your initial post makes no sense whatsoever.

If anyone wants to entrust his hashing power to you despite that, and without having a clue what their hashrate wil actually be used for, I suppose thats their business. Nothing I can do about that, but  I do feel someone should point it out.

As for the 51% attack; no you alone wont pull it off obviously. But you are not alone. There are lots of similar 100+% pps "non"-pools, meta pools and pseudo pools emerging lately. No one knows where their hash rate goes to, or what its used for. So no one knows if they cant be combined and rented to the highest bidder for whatever purpose. You dont have to be a mother theresa to be concerned about that potential, all that is needed is owning coins.  Half this forum is deeply concerned about deepbit and slush's combined hash rate, even though they provably mine their own blocks, there is no big mystery there. And no demonstrable lying.

4. Does it potentially harm bitcoin?

I cant. Only you can. By actually answering a very simple question.


There is good evidence you are at least lying.
That doesnt mean you will set up a ponzi scheme for mining shares or steal your miners coins, I never accused you of anything beyond apparently not speaking the truth. If people have fear, uncertainty and doubt beyond that; well, I cant blame them.

Come up with a sensible response to how buying mining shares above market rate with bitcoins allows you to sell bitcoins for cash without relying on an exchange, and that fear will likely be put to rest. You may not think its worth responding to me, but I dont think Im the only one wondering.

As much as I agree with you, its not going to happen. Miners are humans, therefore lazy and greedy.  If they can avoid setting up something ilke p2pool and make a 10% gain, most will take it.

Now Id like someone who is more knowledgeable about the technology to shed some light on what the potential ramification of this are, when gpumax, clipse etc would amass a substantial part of the hashing power and a single individual rents it for malicious intent. Do they need 51% or do they have a chance at an attack at less than 51%? What damage can they do or what profit can they extract ?
