I just got this mail. My name is not "David":

I didn't click the link, but I'm pretty sure it's not safe.

Beside here, is there a place to report it?

I'm trying to register a new account at give me coins, but they require a PIN, and I don't know where to get one.

Pointers, welcome!

I remember that when I was young that a storekeeper and a veterinary were arrested because they were reading the unsold scratchable lottery tickets of the former with the X-ray machine of the latter. They kept winner tickets for themselves, and the the rest to the unsuspecting clients of the shop.

Are you sure that the PrintCoin seal is also opaque in non-visible wave lengths? Or that the black ink isn't more opaque than the seal? It's all about contrast.

Yes, it will :-).

It has two drawbacks, though:

It stores not only the wallet but also the block chain cache, which is grows as time goes by, inside the app.

Furthermore, If you don't use a client+wallet bundle often, when you launch it, you have to sync download all the keychain blocks that have been since the last use, or you'll have to copy them manually, which means that you risk to mess up and overwrite the wallet.

I've written a new script that that only stores the wallet and creates a symlink in the ~/Library/Application Support/Bitcoin, but I haven't tested it yet (and I'm not home right now).

I know that backing up the wallet.dat file is enough, but I don't know if there are other accout-specific files in the datadir?

__db.001   __db.004   addr.dat   database   wallet.dat
__db.002   __db.005   blk0001.dat   db.log
__db.003   __db.006   blkindex.dat   debug.log


This is related to my OS X post here: http://forum.bitcoin.org/index.php?topic=16258.0

If the Wallet is the only account-specific file, then I'll use a symlink solution that should be much lighter.

The wallet switching user experience is currently sub par on all platform. You must either manipulate folders (and risk screwing up) or use the command line.

I offer here a nicer solution for Mac Os X: Use one Bitcoin.app per wallet, and put the wallet inside the application bundle.

It creates a standalone, portable Bitcoin.app that can be copied around and run as is on any Mac, or stored on an encrypted partition.

Here's the procedure to create a new, empty wallet (it could be automated, but I'm not there yet).

1) Create a copy of the Bitcoin.app and put it in your encrypted partition (let's call it BitSafe.app, for a "bank safe"-type wallet).

2) open the terminal (Terminal.app) and type then press ctrl + d.

3) Again, from the prompt, type chmod +x start.sh to make the script executable.

4) now, we must edit the Info.plist file in order to tell OS X to launch our script instead of directly running the bitcoin binary. Type nano ../Info.plist . From there, find the following lines and replace bitcoin with start.sh .

You should also change the Bitcoin strings corresponding to the CFBundleDisplayName and CFBundleName to BitSafe (or whatever strikes your fancy). This will change the Application name in the menu bar.

Once you're done, press ctrl + o, return then ctrl + x

6) Save a backup copy of the file (it will wake it easier to create new integrated App+Wallet bundles).

You can now open BitSafe.app. A new wallet will be generated inside BistSafe.app. You can have as many of them as you like, and you can move them around for backups and so on.

If you want to copy an existing wallet (located by default in /Users/YourUserName/Library/Application Support/Bitcoin), you must go inside the Bitcoin.app package. From the Finder, right click on Bitsafe.app and pick the "Show Package Contents" option. It will an open new Finder window. From there, go to Contents/Resources/data . You can paste your wallet.dat and other resource files here.

Updating the Bitcoin client:

If a new version of the BitCoin client is released, you can update the binary inside the Bundle. Right click the new Bitcoin.app file and choose Show Package Contents. From there, copy the bitcoin file located in Contents/MacOS/ file and paste it at the same place inside the BitSafe.app package.

Note: I've tried to change the LSMultipleInstancesProhibited from true to false, but it doesn't allow to run multiple Bitcoin clients simultaneously (even if I change the CFBundelIdentifier entry). I'd love to know if it is possible to overrule that behaviour?

Thanks for sharing :-)

I'm sorry, but I don't understand your reply...

Save the profile, and edit it by hand in a text editor (mine is called mem300.ovdr)

You must change the mem param of the performance levels 1 and 2 to 30000.
Then you can load the profile from the command line with
Where N is the id number reported by

However, I don't know (yet) how to adapt the voltage for these lower memory clock rates...


Amazingly, lowering the memory clock increased the hash rate from ~320 to ~325 MH/s

Ok, I got AMDOverdrivectrl to work :-)

(Moved from the tech support forum...)

My motherboard of choice for mining (ASRock 870 extreme 3) can't sustain the heat of two 5970 (~90°C).

I fried two of these already (actually, the PCIe-related capacitors somehow melt). I thought I had been unlucky with the first one, but apparently it's a weak point of the model (which is advertised for its durable capacitors, oh the irony).

Do you have a recommendation of a reliable, dual PCIe x16 motherboard?

Thank you, I'll have a look at that, probably tomorrow.

What can I expect in terms of temperature by underclocking the RAM it to the 300-400MHz range?

I'm trying to underclock the RAM of my Radeon 5970 below the allowed range of [1000-1500]MHz, but even aticonfig --odsc 0,999 gives me an error...

Is there a way to override the limit? I've seen many people around here with similar cards and the RAM clock set at 300MHz...

A last bump before going to sleep.

Coming from a country much smaller than its neighbour, I know where you come from.

Keep in mind that these polls are held to help merchants target the Bitcoin crowd, and that the sample size is rather small since about 1/4^th of the people who read the topic give an answer.

Canada + US is the English speaking America (with all due apologies to Quebec people).
 I also lumped together the UK and Ireland (Europe's native English speakers) even though, historically, they have not always held the friendliest relationships. The same goes for other regions.

As announced (to reach people around the globe roughly equally): Bump!

A new day, a new poll. I tried to be as exhaustive as possible without being too detailed either.

The aim of this poll series its to get a demographic picture of the Bitcoin community in order to attract merchants related to our interests.

Note to the moderators:

For this poll to be accurate, it needs to be exposed similarly to people all around the globe. As a consequence, I plan to bump it every 4 hours. Would you agree with than and not consider it spam?
