I know the 5970's and 5870's are pretty much the 'sweet spot' right now. Hard to find new though. You don't need new. Used ones are MUCH more cost-effective. Yeah, but you have to be careful they haven't been trashed bitcoin mining ... some of things I see guys talking about on the mining forum threads with ham-fisting over-clock changes, machine hang, screen black, etc makes me shudder to think what they just did to their cards ...

Basic concept is sound. If the implementation is well-thought out it should have a lot of utility.
Kind of like a geographic co-located, OTC, trade exchange. Neat.

I'm able to ping mining.bitcoin.cz from all my machines, but workers will only connect from one. I haven't tried accessing from a browser since I'm usually connected via SSH.
... what about the port forwarding to 8332 ... how does it get to both machines from the firewall/router? .. (assuming you have one)

m0mchill,
just sent you a donation for all the sterling work that your miner has done for me .... moved over to phoenix now but your efforts were appreciated.
cheers,
moa

Have you ever seen a person die? Like, not in a video game or a movie? The internet tends to make a lot of people pretend they know what they're talking about. Not that it is any of your business or relevant to the topic, but yes I have. Since you are asking have you? Basically, blaming the type of money that people are using for crimes is infantile and indefensible as a logical argument. Something only a brain well-pickled and infused with statist tosh could come up with ... but then again you think you know what you are talking about so carry on ... it must be the internet doing that to you.

Good work on the miner guys ... donation coming your way.
PS: I don't know to love you or hate you for single-handedly making the network hashrate 10-15% bigger.

Tycho, i have 9 workers so far and i need more! i cannot use more? i don't see the button to create a worker ![Angry](https://bitcointalk.org/Smileys/default/angry.gif) thanks Impressive, 9 workers ... are you becoming some kind of GPU bot-herder? ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif)

Satoshi walked freely amongst us then and answered our questions directly. I felt like I had discovered some secret club of cryptoanarchists. Posts were more like a few a day and it was easy to keep up with all the chatter. There must have been less than 100 members on the forum then.
Yeah, I really liked beeing part of that small bitcoin family we were. I read all the new posts every day and there was this "all new, exciting" atmosphere around. I kinda dislike seeing the forum spammed by all this let's say "less important posts" nowadays because back then it felt like listening to some technology-socialist-anarchist-liberalist gurus. I'm glad Bitcoin is finding acceptance by many people now but it has definetly lost it's secret-elite-flavour. Who's to say there isn't a secret elite club somewhere trading the next, best crypto-currency right now?

I don't know if it would be useful or not, but you may be able to draw some legal parallels between bitcoin and the recent development of an emerging market for IPv4 addresses. See http://www.networkworld.com/news/2011/042511-ipv4-sales.html?hpg1=bn . IPv4 addresses are starting to gain monetary value on their own, even though they are a purely virtual commodity, because they are in demand and there is a limited supply of them. There will never be any more IPv4 addresses created, and the world has essentially run out of unassigned ones. Very, very good point ... in many essential legal respects bitcoins are exactly like Ipv4 addresses. There is a network of peers maintaining the assignations (the DNS servers), they are limited in number, and now they are trading. We just need a client well suited to swapping IPv4 addresses amongst users and some industrial strength security, to make it more bitcoin-like.

There is yet another reason, that is bitcoin specific, on why inflation would be bad idea. Interestingly, it is the same basis why inflation is bad for other currencies, but is a different mechanism for undermining confidence in the bitcoin system.
We already have good evidence that network difficulty, hence hash-power and security are correlated quite tightly with bitcoin exchange rate, i.e. the price basis other goods, service and currencies. As the value of bitcoin grows, so does the security of the network due to the strength of the computational power backing it, since miners have an economic incentive to compete harder for the bitcoins on offer. At this stage, it is something of a virtuous circle.
However if there were to be an inflation expectation different than that already planned for then the incentive system in place that is driving the increase in network strength would be undermined. It is not just the dilution of the currency unit that would be affecting economic confidence but the pricing dynamics of securing the bitcoin network, that appear to working just fine at present, would also be affected.
Simply put: inflation is a threat to network security.
EDIT: seeing things in this light, it is no longer a question for economists but it is now in the hands of IT (where, perhaps, it should have been all along)

Well do you have 100k btc?
(I'm sure we can find a buyer for you.) All hat and no cattle.

Mod note: split from "BitCoin Coming to an End?"I'm sorry to whale on the noob BUT the title of this thread is both idiotic and provocative.
Perhaps we should have special section of the forum set aside for idiotic noobs to post provocative questions, and we don't have to read the titles at all?

Well I'm going to celebrate 6 million bitcoins in existence and no signs of the network weakening yet with a bitter, dark, cold ale ...!
Hurrah.
|
|

Just be straight up and answer the questions that are asked to the level that is required ... no need to hide anything.
Oh what a tangled web we weave when at first we seek to deceive.
Bitcoin has got nothing to hide or need make no apologies, it will stand and compete on its own merits.

Under-clocking mem. clock on Linux can be down simply using the little tool linked to in this thread. http://bitcointalk.org/index.php?topic=4806.msg74527#msg74527 Read what "Ian" has to say ... you just have to move the slider down to 300 (or whatever you choose) and when you go back to "$aticonfig --odgc --adapter=all" on CLI then low mem. speeds will be available ... then do the "aticonfig" command for clock speed you want (all at your own risk of course).

Maybe the linux device /dev/vga_arbiter
is causing issues?

Is it really dependent upon the Twisted package?
It is not installed on my system but phoenix appears to be running fine.
Edit: sorry it is there, listed as package "python-twisted" on ubuntu 10.10 (also there are other "python-twisted-*" packages in default installation twisted stack)

Can confirm following hashrates;
linux ubuntu 10.10, SDK 2.1, fglrx 11.2, HD 5970, phoenix.py kernel=poclbm vectors aggression=12, worksize=128, gpu-clock 725, mem. clock 300 : 285 Mhash/s (same as poclbm but uses less power ~20 watts less)
and then this bolter ... BFI_INT enabled 312 mhash/s ! (what exactly does this flag do ? suspect it is something to do with optimising integer arithmetic ALU)
Looking good, this is just great if it works long term after some testing, can now run my rigs cooler and quieter with more speed, where's that donation address i want to throw some bitcoins at you guys!
Down clocking memory on linux is big kudos and BFI_INT is off the charts ... unfortunately once this gets widespread then difficulty is going to take another hike ~10-15% I estimate.

I'm not sure you are really an engineer are you? 400kWatt is a pittance in the big scheme of things.
It should be remembered that the current primary system USD has a massive war machine in place enforcing the monetary order of dollar hegemoney ... are you railing similarly against the green issues raised by the US military?
It's all about perspective, bitcoin is far superior at the task that it id doing, in terms of energy expended, than the current dysfunctional system, but if you don't think so, come up with some real numbers for the current system and live by your calcs.

If I saw an assassination market using Bitcoin, I think I'd contribute to that effort myself, though I know saying that won't win me any points here. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) EDIT: Just to be clear, I mean I'd contribute to the DOS effort against such a thing, not to the assassination market! You get points from me. There are a lot of extreme ideologies thrown around on the internet without regard to their practical application. I'd sink a good ship to prevent it from being used for evil any day, and I think anyone who supports the freedom for assassination markets to exist "on principle" should be made to be present during the event--after spending an hour talking with the person before and then having to sit alone with them in a room after. Then they have to explain their principles to the person's family. And raise their kids. What if the CIA put hit out on Ghaddafi in bitcoins? Where would that leave all you holier than thous? How did they pay to have Saddsam Hussein offed anyway, your taxes, in USD to hired guns most likely. FFS how sanctimonious are you going to get on us.
