samething happening to me, I never clicked the "new" button even once, had always used the address I first got. But I am seeing 6 new addresses currently sitting in my address book.

Though I often wonder, but never dared to try, 0.00 fee. Does it work?

I just transferred two bitcoins to http://www.tradehill.com with no fee...

how long did it take? One guy said it took over 10 hours for his 0 fee transaction to appear in mtgox
2144  Bitcoin / Bitcoin Discussion / Re: I just got hacked - any help is welcome! on: June 14, 2011, 04:44:17 PM
I wonder if you had adequate antivirus on your windows machine? It'd be very hard for a trojan to take control of your computer if you had adequate security software, that can detect trojan behavior. Plus Win7 has some default security built in like UAC. I think it'd take a seriously good hacker (like top 0.001% in the world), to hack a windows machine, over the internet, with firewalled router + good security software + UAC turned on.

yes, this is why the bitcoin wiki recommend that you delete blockindex.dat file each time you switch wallet

0.0005 is great. The 0.01 fee was too much for frequent transactions.

unless your OS hangs constantly(which it shouldn't, even Win7 is quite stable and can run for months without problem), I don't think it's worth it. Just set your BIOS to auto reboot on power loss.
2151  Bitcoin / Bitcoin Discussion / Re: Security again: Before using TrueCrypt - read the freakin manual on: June 13, 2011, 04:52:46 PM
Why not simply use 7zip to create a archive of your wallet.dat with a password? 7zip does use 256-bit AES to encrypt the content of the archive, same as truecrypt. Just choose a strong password, and you'll be fine.

Can we use the same receiving address(worker name) for multiple mining GPUs?
2153  Bitcoin / Pools / Re: BTC Guild - 0% Fees, Long polling, SSL, JSON API, and more [~1500 gH/sec] on: June 13, 2011, 01:11:03 PM
Is there currently a reporting problem?  I see this:

9,553 workers at 1,536.46 GH/s
Round Time   3:36:20      Round Shares   4577435

Statistically speaking this is extremely improbable.  Is all the server shuffling creating problems for the website such that it doesn't really know when a block was found?  Or are we really just winning the anti-lottery?


No, it's actually not that improbable. Just means the pool is unlucky, other pools are solving the block before we can.

As I understand it other pools solving blocks doesn't affect our chances of solving a block at all, it is random chance when we hit one.  Having 1500GH/s just means we buy 1.5 trillion lottery tickets every second.  Sure we start using a new block header for hashes every time anyone solves a block, but that doesn't change the odds.  According to my limited understanding we have a 95% chance of finding a block within 1.5 hours at that hash rate.  A 2 hour round is an anomaly, a 3.5 hour round seems damn near impossible.  Not actually impossible, but so unlikely as to make me wonder if something else is going on.  It is certainly possible I'm misunderstanding things, I am no statistical genius.  Please educate me.


Then there's round #493, that were solved in 55 seconds, that's near impossible too
2154  Bitcoin / Pools / Re: BTCguild issues? on: June 13, 2011, 02:22:40 AM
could just be a difficult block. Some of them took 3 hours

I'm pointing my 410 MHash/s to eu.btcguild.com since 4 hours now and earned 0.01366009 BTC. Something is still wrong there, at least for my account...
2155  Bitcoin / Pools / Re: BTC Guild - 0% Fees, Long polling, SSL, JSON API, and more [~1300 gH/sec] on: June 13, 2011, 01:41:59 AM
Can anyone give me some advice on getting my stale rate down. Over a 24 hour period, running 13 gpu's on BTC Guild, I am getting a 5.2% stale rate according to the stats on the my account page. With deepbit I was getting around 3% and with slush I was getting around 4%. None of these numbers are good when I see people saying they get less that 1% stale rate.

Any ideas? I am running phoenix using the phatk kernel. Below is my command line:

phoenix.exe -u http://XXXXXXXX:YYYYYYYYY@us.btcguild.com:8332/ -k phatk DEVICE=1 VECTORS BFI_INT FASTLOOP=false WORKSIZE=256 AGGRESSION=13

Thanks.

Toning down the aggression can help.  Additionally, the IRC chat has universally agreed that phoenix's stale rate is completely terrible right now, since it seems to ignore clearing out its work queue after receiving a long poll.


Pool Status Update:
US West is getting bogged down compared to the other servers.  I'm working on shifting some of the frequent MySQL tasks to the slave pools to help it handle the load.  Eventually the frontend will get moved to a separate server so that the pool itself on US West is not significantly affected by website load.

Which miner do you recommend to use?

Nice settings, but I find the web interface design a bit lacking. Need to look a bit more web 2.0ish and cleaned up. Right now it looks like a site made in 1998
2157  Bitcoin / Bitcoin Discussion / Re: Factors that affect the price? MtGox vs Tradehill? on: June 12, 2011, 05:04:17 PM
I think the fact that mtgox had so much trouble with dwolla's new API change, causing many people not able to move their USD to and from mtgox, was the cause of the recent crash. All other exchanges just followed mtgox' price.
2158  Bitcoin / Mining support / Re: What are the steps I can take to save power on mining rig? on: June 12, 2011, 03:57:15 AM
Thanks for the reply, the PSU is a corsair
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139007

When I have 3 x 6970 in the rig, the system will start for 1/2 a second and then dies, nothing would power on (though mobo still show the small power indicator light). If I put 2 x 6970, then system would boot up fine.

A 1000w psu should be more than sufficient but we need to know what psu you are using. I do not recommend undervolting any cpu below its specs. Regardless if it seems stable, long term damage still applies. Also please be more specific on what you mean by "rig won't start". Do the fans power up on the cards? Does anything power up at all? We need more info.

A lot of HongKong ebay sellers has them for $5, but you have to wait a month for shipping
