With all that is going on.. I feel it is important that the news be read at the top of the forum. Right now it is fairly easy to glance over it, but the announcement about the mtgox hacking is a must-know for any bitcoiner and should be highlighted more thoroughly I believe.

I was reading about bit rot and began wondering about my backup ideas. If I copied my wallet.dat file 1,000,000 times across the entire partition of my usb drive... or perhaps created ~20 partitions that each contained a copy of the wallet.dat file... Would I somewhat protect myself against bit rot? It sounds like it only affects single bits at a time and on a specific area of the drive. So if I made multiple copies on the same drive then surely one copy would work correct? Obviously I will be replacing my backup media every year or two but the less often I have to the better. If I could just create 1 million copies of my wallet.dat file and leave it on a USB until the product itself deteriorated that would be amazing. Somebody told me about OTP (One Time Programmable) solutions as well but they are not easily attainable, or so it seems. Know of any good links? |

Come on now people... we are experiencing a massive influx of users.
Let us use this to our advantage and place web 2.0 "share" buttons on every page of this site.
It doesn't have to intrude on anything whatsoever.
If nobody knows how, I will offer up my time to create a custom banner of the top 10 "submit your link" type sites as well as email/browser favorite saving and we could place it right up beside the title of the "Bitcoin Forum" in the top left of the page perhaps?
I could make a "Share this page" html button that opens a list of "shareable" sites when hovered over or whatever you want really...
Or there are tons of tutorials online that will help whoever is running this site set it up themselves.
Either way, it's pretty silly not to have something like that on a site such as this.
If the right person tweets or facebooks us... we could receive free advertising worth tens of thousands of dollars... and it doesn't cost us a thing.
PM me if you need me to do anything. I don't check the meta subforum often.

I have seen a lot of "0%" pools pop up recently...
All of them seem to state "you are getting exactly what you deserve" ... "you get 50 BTC divided by the amount of work you contributed" ...
But there is nothing that mentions dividing of transaction fees, anywhere.
So am I correct in believing that the owners of every major pool simply pocket the transaction fees? (And ask for a "donation" on top of that?! (some of them!))

This is doing quite a good job of annoying me.
I have 6 cards plugged into MSI 890FXA-GD70 motherboards... all with pcie 1x extenders that I have cut/shorted myself.
I can start up all 6 cards fine. The rig runs great for a few hours.
Sure enough... sometimes 5 minutes in, sometimes 12 minutes in... card number 4 (according to aticonifg, and always/only-ever card number 4) will receive the dreaded "Verification Failed, Check Hardware!" message.
I am not even 100% sure what card it is because all of them feel hot to the touch on my setup.
I have the exact same setup on a MSI 790FX-GD70 board... and I have yet to notice this, but then again there are only 5 cards on the board.
Anybody else experience this problem? Know any possible solutions?

I figured you coding types would know best...
How difficult is it to "hack into" a default ubuntu install that is connected to the internet 24/7 from behind a router.
Is it even possible at all? If there are no remote login programs enabled by default? (I am not even sure if there are any, I am more of a windows user.)

And why is it not necessary to backup any of the other files in your bitcoin folder in order to re-create your wallet?
Also: will the "format" of a wallet ever change? Will it ever need to? Even in 50+ years?

So with all this talk about hacking, everybody is rightfully paranoid about their wallet.dat security.
I was thinking... wouldn't it be possible to generate a bitcoin address whilst OFFLINE/not connected to the internet? On a fresh ubuntu/linux install...
If you send the coins to that wallet after encrypting it securely and uploading it to a few remote cloud storage type services... and then sent some bitcoins to an address you had generated in the wallet... that wallet would still contain the coins you sent it correct? Even if it was NEVER connected to the network?
So that in 20 years if I wanted to access my "rainy day" fund, I could retrieve my wallet.dat file that had been encrypted on "the cloud", pop it into a bitcoin client, and my coins would magically appear? (After a massive block download wait I assume).
Am I right?
What is wrong with this idea? Anything?
I am only worried about trying it because it means I would never actually have any proof that the bitcoins were indeed in the wallet, if I never connected to the network that is.
Couldn't somebody else create a wallet and generate the same address as me, since I never told the network about my address?

So here is my "safety plan"...
1) Install ubuntu to a USB Hard Drive and select the option to "encrypt hard disks".
2) Install bitcoin on the ubuntu OS that is running off my USB hard drive with encryption.
3) Done.
You would need phyiscal access to my USB drive AND the login password in order to transfer and bitcoins.
The only other step I might include would be making a duplicate copy of that USB HDD and uploading it to "the cloud" but I don't know how to do that yet...
Would it be even "safer" to use a lesser known distribution like Fedora, CentOS, or some other linux variant that is less commonly used to run a bitcoin client perhaps?

How do I:
a) install the very latest version of phoenix miner to my persistent linuxcoin usb flash drive?
b) install (and switch between) sdk 2.1 (since it is 2.4 by default and poclbm favors 2.1) to my persistent linuxcoin usb flash drive?
c) pop open all 6 of my poclbm or phoenix command line miners on persistent linuxcoin startup? It is such a pain to open up 6 miners using the start_mining script...
Please leave your Bitcoin address in your answer post.
The first person to leave a competent answer that is linux-noob-friendly for any question will receive 0.05 BTC sent to their Bitcoin address. Answer all 3 and you get 0.15 BTC.

Most every "professional" forum on the internet uses vBulletin.
There are some good reasons for that.
Why are we any different?

I have a DIR-655 Dlink wireless router I am using to supply internet access to 4 mining rigs each running about 5 cards.
I am having troubles connecting to deepbit.net occasionally using phoenix miner. I will mine great for a few hours/days but eventually some of the cards go offline and never come back on. This is always preceeded by a "deepbit.net unavailable" type message...
Would It make sense to optimize port 8332 or my router in the QOS/traffic shaping section?
I have read phoenix miner is no good at re-connecting from downed internet connections (I am using the version available in linuxcoin v0.2a, not sure what version of phoenix it is, perhaps I have to upgrade?)
Any suggestions are appreciated!

I purchased 3 * 5870 OC edition Gigabyte cards through Newegg, and 3*5870 XFX cards as well.
The xfx cards can run at 960/300mhz core/memory and spit out 410 mhash+ at ~75 celcius.
The OC edition gigabyte cards struggle to stay under 90 degrees celcius even at 880/300.
Anybody else notice this? Are the OC edition Gigabyte cards no good for mining?
I have 6 * gigabyte 5870s (non OC edition) that run great... 410 mhash at 80 celcius maximum. So confused :S

Just an outsider's view here...
Lots of linux/apple/ios/android apps...
But the fact of the matter is... 80%+ of the world still uses the internet through a windows platform.

Is it "acceptable" to most reputable PSU companies to run a PSU at 50% load 24/7? 75% load 24/7? 100% load 24/7?
I doubt they would honor their 5 year warranty if you kept blowing through PSUs every year or two, no?

I am considering spending almost $1,000 on 3-4 gold rated PSUs.
Seems to me they are little more than transformers.
If I could purchase 4*$30 PSUs simply to run the motherboard/cpu power... could I note create a massive single 12 volt rail that distributes power to say 30-40 video cards via pcie connectors at once?
I guess it would really suck if THAT power supply broke down... but still - anybody tried it or similar?

So I just setup my first dual PSU rig...
Two raidmax gold 850W PSUs (one with a shorted green + black ATX power cable to keep it powered on) powering 3 * XFX 5870s and 3 * GIGABYTE 5870s (OC Editions)...
All cards are connected by extension cables except for one which didn't want to work in an extension cable for some reason so it's plugged into the mobo.
I start up the computer, all is well...
I start the first few miners, all is going smoothly.
I begin to check the temperatures about half way through setting up the miners in a terminal, and notice that one or two of the cards is already at 90 degrees celcius. Which is odd... they are 5870s with 950core/300memory clock settings hard coded to the BIOS with almost nothing else changed.
Some of the cards (presumably the gigabyte's) are running just below 80 celcius like they should be... but 3 of the cards are just burning right up to 92-93 and sitting there.
I have my fans on continuous all the way from 0 to 100, so they should have been running at about 92% at that point in time.
Something starts to stink. Not sure what it is... assume it's just cheap glue burning off the pcie extension cables and/or that "fresh plastic smell" coming from the brand new cards perhaps.
I stupidly leave the room for a few minutes... only to come back and find that the room is now filled with a light grey smoke.
The computer is still working thankfully, and all cards are still mining... but I obviously shut it off ASAP and that is where I am at now.
The weird thing is... everything looks ok. The cables, the cards, the mobo... I can't tell exactly where the burning smell/smoke is coming from - I can only assume that perhaps xfx of gigabyte can't take the 950/300 clocks and they are literally burning up?
The PSUs were only running at about 85% max.
Another possibility is the fact that I have pcie power cable splitters? But this is not a problem on any of my other two rigs...
Anybody have an idea? Should I be "un-shorting" the green+black wires on the second PSU as soon as I short them to turn it on or something? Very worried about turning this baby back on...

So I have at the moment 2 rigs of 6 video cards each hooked up to a single wireless/wired router.
I just noticed that my hashing rate had dropped on my pool stats sheet, so I went to check it out... assuming a card had frozen.
Nothing frozen, but my router was acting up for some reason. I was unable to access the internet for a period of a few minutes.
I am mining with linuxcoin and phoenix miner on both rigs.
On one rig, all cards resumed immediately.
On the other, only half of the cards resumed and the other still say 0mhash...
Any idea what could be causing this? Or do you know of a possible solution?
