Since I'm gonna lose it anyway... My username is ovidiusoft.

I use 24h average, too.

Correct. Even more, there are numerous reports that mining separately is better than CF (more Mhash/s).


Yes. Of course, it does depend how much RAM and CPU the miner needs, but that is not usually a problem.

I don't know what would happen. The market as it is is crazy enough so I don't even dare to try to guess . What I do know is that (1) there is no 100% security, (2) bad things that could happen, will happen sooner or later, (3) problems get fixed.

Obviously, we should try to make the system better *before* attacks can destroy it. But even is it does get destroyed (I don't believe this will happen, I think Bitcoin being declared illegal is much more probable), I think that it's already proven that people want such a system. And what people want, people get. It might not be called Bitcoin, but in the end, it doesn't even matter.

Nobody *needs* to mine. It's a choice based on passion or desire to make a profit. If we leave passion aside, nobody should mine at a loss for a long time, they should simply buy Bitcoins.

You obviously mine at a loss and/or don't believe Bitcoin will succeed in the long run, so you're trying to make money some other way. You're offering a deal which you yourself believe is a bad idea/unprofitable (or you would do it for you). While this is not a scam per se, it is immoral.

So let me see if I got this right. They say that a fan sucking air from the heatsink will clean dust that can't be removed with the fan blowing towards it? Who's the idiot who thought of that?

This type of attack is considered "probably not a problem": https://en.bitcoin.it/wiki/Weaknesses#Attacker_has_a_lot_of_computing_power . For someone to do it, it would need not only to have such processing power, but to also maintain the attack indefinitely. Running costs of a few millions a month will only be justified if the attacker gains more than that AND he has no other means of achieving the same results.

Botnet owners will not do this, because they can use their power for much more profitable "services". Governments can filter or make Bitcoin illegal with less effort. So that leaves us a very rich private person who really-really hates Bitcoin. Doesn't seem to be a problem.

Try with this:


Make sure that the file is executable. Also make sure when you copy/paste the text to keep the backticks ` around whoami.

You're right, sorry for that, vim seems to hate me lately. I fixed it, everyone please re-download.

Thank you! Also, I want to publicly acknowledge that I received the 10 BTC bounty from gusti.

The script can be downloaded from http://dl.dropbox.com/u/16757143/overclock-test.sh , shortlink http://db.tt/S73vRHk . It's written in bash and uses bc, awk,
pkill, so you need to have these installed.

The script starts Phoenix and keeps changing ram/gpu frequencies in set intervals. It also monitors temperature to prevent overheating and determines average hashrates for each ram/gpu frequency pairs. It writes the results in a file called 'results.csv.TIMESTAMP' in the current directory:


If the machine locks, the last line written to the file will be the last passed test. Please edit the script to change your settings and start slow (with values that you know work without hanging your system). I only tested it with Phoenix 1.50 on Debian and Ubuntu, but changes required for other versions/miners should be minimal.

I hope it's useful! If there's interest, I can start a new thread for it and develop it some more (easier to configure and working with other miners, for example).

No problem for me either. If it's ok with you, gusti, I'll add a suggestion to donate to my address and upload the script to my Dropbox public folder. Since you were the one requesting this script, I think it's only fair to let you decide.

...but because I can already hear the voices shouting "But I want my passwords synced across devices! Pronto!", the good enough solution is to place the password database in Dropbox so it's automagically synced. The better solution would be Sparkleshare on your own server, when they'll have a stable client for all major platforms.

I'd like such an interface, too.

On these systems you can probably only do CPU mining... without much success. As for upgrading, you'll probably be interested in getting the best GPU / U density. If you can afford it, Supermicro has nice systems that can host 2 double-size/full-length gfx cards in 1U: http://www.supermicro.com/gpu/ .

However, do the math. The hardware is going to be *really* expensive and it's going to be a reaaaaaaaaaaaaaaaaaaaaly long time until you will recover the invested money (if ever). I was in the same situation as you and I dropped the idea in favor of CPU mining (otoh, I don't have old P4s).

Bitmarket is not a "real" exchange. They act as intermediaries for matching orders, and as an escrow for BTC. You can't transfer other currencies to/from Bitmarket, the transfer get done outside of Bitmarket. There is significant lag with this system, something that's not good considering current market instability. There is also a significant risk of getting scammed (even if you don't use PayPal).

KeePass - http://keepass.info/

It's the best I could find. Very powerful encryption, versions for all desktop and mobile OS-es, and has a "autotype" function so you don't need to copy and paste your password, it will fill it directly to your browser (or any other app). Also has a very good password generator. I use it for some time now (2+ years) and I couldn't be happier.

After hashing, very little. But:


You should assume that if you entered your password while logging in after sept 3rd, it was intercepted while still in plaintext. Change it.

I would definitely support anyone planning to launch a Bitcoin product, during development and testing phases. Unfortunately, OP didn't ask for development support/testing/advice, he presented Bitcoinica as a finished and launched product. At this stage, I would stop considering myself a beta tester and start being a customer. As a customer, I want to see company papers and IDs.

OP, please state the status of the project. Is it a launched, open for customers service? If so, can you provide company papers and proof that you operate legally? Can you provide either source code (under NDA is ok, I think) or proof that a respected company audited your source code? Can you provide us with hosting/operation details so that we decide if your setup is safe enough?

@Matthew, I believe you are wrong. Fast-launching something on the market should *never* be done illegaly. If you need to have permision to open a certain kind of company, you do it. If you're afraid someone would do it before you and you'll waste effort, just don't do it. Period. Anyway, why do you think that launching later is bad? As long as it's good competition, the market will embrace it.

I believe we have such a large amount of professional scams in Bitcoin (not talking about people not returning a 5 BTC loan from IBB) because customers are willing to take insane amounts of risk without even blinking. I also believe this is hurting the Bitcoin economy as a whole. Do we really want Bitcoin to be branded forever as the easy way to buy drugs and a scammer's paradise?

Note: I am not implying OP is a scammer. But, until he proves he owns a company operating legally acording to his local laws, I believe he should not be trusted, no matter how "cool" his services are.

But I hope you do know that you're still a democracy, right? I don't see tanks on the street and military shooting people. There is nothing stopping you and your fellow citizens going out and voting, or going on the streets if voting is not effective/fast enough, and changing the way your country is run.

If enough people in Illinois would simply stop paying taxes and non-violently block police activity (and any other relevant structures) guess how much time it will pass until things start changing? 1 year? 1 month? Try it.

Being from a country (Romania) where things are generally worse, I see every day people complaining and doing nothing, not even figuring out that things don't happen to them "just because", but it's their own fault. Just do something.
