He basically says that he is generating trillions of addresses non stop and getting a few collissions that will grow over time. His logic is that the entropy of Armory, Bitcoin Core, Multibut, Electrum etc. (and generally any other wallet that uses a RNG based on software) is flawed and results in a highly reduced keyspace, which will result in collissions with enought computing power and space devoted to private keys bruteforcing.

See: https://bitcointalksearch.org/user/hash-hyena-380718

This guy is either trolling for the sake of it, or he is going to bundle some malware into his upcoming "bitcoin cracker".

Anyway, if you don't trust your machine's RNG, there is a way to use your own entropy via restore backup feature: https://bitcointalksearch.org/topic/--673035

Alan, what do you think of "Hash Hyena" claims?

What is your position on that? I remember that Dabs (I think) requested a feature in order to input "true entropy" from a physical source (a decks of cards, dices, etc.) - how's the progress on that? It might be a good thing to mitigate software RNG issues, but I assume it might be difficult because an unssavy user might make entropy worse by not using "true entropy" right.

I am switching over from bitcoin-qt to armory.  I have a wallet that I want to import the addresses to Armory on an offline computer.  Whats the easiest way to do this and once imported how can I send the btc to a newly generated offline address. 

Last time I tried importing private keys to Armory from Bitcoin Core there was no support for importing compressed keys in Armory. So, right now you can't.

Why not just send the coins to the new address?

I am setting up the new armory wallet on the computer that had my old bitcoin-qt wallet was on and I am reformating it so it never touches the internet.  Don't worry I did back up my old wallet.   Smiley.  I would feel more comfortable importing the keys then connecting the old wallet to the internet and sending the btc. 

Switch to expert then double click a wallet

I apologize if this has been already mentioned, but is it possible to decode somebody's private keys from a .signed transaction (Armory-generated) data file? Is it safe to keep those files (with offline wallet signatures) on the system or better to erase them immediately?
I think it's safe to assume that you cannot get private keys from a .signed transaction file, as that would be a pretty big breach in security. E.g. malware on the online computer could grab a .signed file and spend your money before you have a chance to broadcast your legitimate transaction.

Sometimes it feels like you used the "time remaining" algorithm from Windows 95, such as when the database rebuild progress displays 1.5 minutes remaining for 10 minutes.

One thing I've learned over the course of building Armory is that those time-remaining bars are very difficult to get right.  Especially when it comes to things like downloading data that fluctuates in speed rapidly.   I have an extensive background in signal processing, yet I still can't get it right.

On the other hand ,there is a flaw in my algorithm -- it seems to use CPU-timings instead of wall-timings.  Typically this results in the system reporting that it took 2 sec to move 1% of the bar, instead of 3.2 or whatever.  This leads to very optimistic estimates.  I've been meaning to go in and figure out what is causing that, but I haven't had it on my priority list for a while.
I figured out the set of conditions on my systems under which the time-remaining bars are accurate and not accurate.

Time-remaining is accurate(*) when there is sufficient memory allocated to the machine such that it doesn't have to use swap.

If the machine starts swapping, then the time to complete a blockchain scan increases (apparently) without bound, but the estimates do not.

That would fit with using CPU timings, because the process is not using using CPU while it's waiting for memory to be moved to and from swap.



* "accurate" means error less than 1 order of magnitude

PPA and 0.9.3 already installed and running. Why don't "bitcoind getinfo" return version info like normal?  

Do you have both bitcoin-qt from the PPA and bitcoind from the Ubuntu repo installed? Do a "dpkg -l bitcoin*", if you have both "bitcoin-qt 0.9.3" and "bitcoind 0.3.24" installed, then do a "sudo apt-get upgrade bitcoind" to upgrade it to the PPA version.

why should i need bitcoin-qt?  

everything's working fine, btw.  i have 0.9.3 core and 0.92.3 running just fine and top command shows bitcoind running.  i also already have the PPA installed.

You're right, you don't need it, I was just trying to guess what might be going on such that you have bitcoin running from the PPA at the same time as having the bitcoind stub from the Ubuntu repo, and this was the best reason I could imagine...

As marcus_of_augustus already noted, it shouldn't affect you much. If you want to keep troubleshooting anyways, please run these three commands (while bitcoin is running) and paste the results back here.

Code:
COLUMNS=120 dpkg -l bitcoin*
file `which bitcoind`
pgrep bitcoin | xargs -Iz ls -l /proc/z/exe

I went ahead and installed the newest version of mint.
I then reinstalled bitcoin-core through the ubuntu ppa.
Now when I'm trying to run armory it is asking for an installation directory..
does anyone one know where it gets installed through a PPA install?
or am I gonna have to download and install the linux zipped file?

When I installed the bitcoind package from the PPA in LM17, it installed to /usr/bin (so that's the installation directory for the PPA version).

My fresh install of Armory was able to automatically locate it there, so it's a little strange that your Armory didn't automatically locate it, but maybe you're not doing a fresh install?

Regardless of all of this, I'd just follow etotheipi's instructions, they look best all around to me.

why do we get this on version check:

Code:
cypher@ubuntu:~$ bitcoind getinfo
bitcoin is very out of date and has been removed.
Please see upstream sources at https://github.com/bitcoin/bitcoin/
or the PPA at https://launchpad.net/~bitcoin/+archive/bitcoin
cypher@ubuntu:~$

the bitcoind rpc command functionality has been removed, you have to now use bitcoin-cli for rpc calls from the command line

Code:
bitcoin-cli help

will give you the full list.

Code:
bitcoind

is now used only for launching the daemon.

Use the Secure Downloader within Armory.  It was designed to make this easy.  And it's especially easy on Linux:  two ways to get to it:

(1) Announcements tab at the bottom
(2) Help->Update Software

Select Ubuntu and 32/64 as appropriate.  Click on Bitcoin Core 0.9.3.  When it's done downloading, it will automatically check the digital signatures on it and then adjust your settings to use it.  Just restart Armory.

Okay, tried to update armory through the .deb file 13.10.
I'm running Linux Mint 16 petra.

it gave me an error and told me I had to run sudo apt-get install -f from the terminal.
It wouldn't let me open a terminal window, so I restarted the system.

Instead of booting to the Linux Mint logon screen, it now gives me the Ubuntu 13.10 startup screen but never gets to logon.

I went into linux mint recovery and did the sudo apt0get install -f from there, but rebooting  the system still gives me a stuck screen that shows ubuntu 13.10.

Any ideas?

I would guess (just a guess though) that something was messed up before you installed the new .deb, and that installing the .deb triggered something. In other words, it seems unlikely that this is an Armory issue...

I don't know much about desktop environments/X on Linux, but maybe this will help. After booting, switch to a terminal screen with Ctrl-Alt-F1 and log in. Take a look inside these logs to look for anything suspicious:

Code:
less /var/log/syslog
less /var/log/boot.log
less /var/log/Xorg.0.log

Like I said, I probably can't help, maybe someone else here can... my honest opinion: you're probably better off seeking support in a Mint or Ubuntu forum.
