1042  Bitcoin / Project Development / Re: Sigsafe: A NFC key tag for signing bitcoin transactions on: September 11, 2014, 04:37:38 PM
I'd suggest you keep working on the specification and tests - doing NFC correctly is not that easy (in a portable & working way), this is already great work and can turn into an even greater resource.

I don't think you should count on a commitment by a wallet developer to continue - I didn't get one, Trezor had to work on their own wallet, Mycelium are doing their own device ...

And yet you got GreenAddress?
1043  Bitcoin / Armory / Re: [HOW TO] Get the needed packages on your offline computer (Synaptic PM) on: September 11, 2014, 06:04:37 AM

I'd think my post could be done from the command line too, as Synaptic is a GUI for apt.


It's just two different approaches I guess, one from a "developer mindset" and one from a "user mindset".  Smiley




1044  Bitcoin / Project Development / Re: Sigsafe: A NFC key tag for signing bitcoin transactions on: September 11, 2014, 05:25:08 AM

I'd love to see this go forward.

Maybe write a nice email to (Android) wallet developers and see what you get for feedback? I don't think there's more than 10.
1045  Bitcoin / Armory / Re: [HOW TO] Get the needed packages on your offline computer (Synaptic PM) on: September 11, 2014, 05:06:55 AM

That's cool. I didn't know that script was available and rather than waiting for offline bundles I looked at ways to do it myself. With Synaptic offline I also like that I can add other packages or get updates to my offline box, pretty much the same way as I would on an online PC.

[...] My next problem is that I have tried mining on 2 Bitcoin sites (Slush's pool being one of them) and I can't get my miners to work with Slush's pool at all, so I used another site and managed to get my Gridseeds to mine BUT, again I can't change the individual frequency and they only mine in scrypt mode, also all shares are rejected. [...]

You will have to mine with scrypt on a pool that supports scrypt. Slush's bitcoin pool won't.


As for settings, I used part of https://github.com/davidmaitland/Gridseed-PiMiner and it worked out of the box for me. Did my own tweaks to it, but their config file containing

"baud=115200,freq=850,chips=5,modules=1,usefifo=0,btc=16"
works. You don't say which Gridseeds you are using though.

I think it'd be good if you made the offline version of Armory to work with Lubuntu.  As most people use older hardware for offline machines plus the latest Lubuntu 14.04 is an LTS version.  [...]

I installed on Lubuntu 14.04 (works for others too). It's not that hard to do: https://bitcointalk.org/index.php?topic=777625.0
1049  Bitcoin / Armory / [HOW TO] Get the needed packages on your offline computer (Synaptic PM) on: September 10, 2014, 05:54:46 PM

Just installed Armory on a Lubuntu 14.04 and thought I'd write it down. Hopefully this is of use to others too. The added benefit using Synpatic offfline is that you can easily add other packages from the official release without having to rely on any third party. It's a lot of text, but once you got the hang of it, it is actually not that hard to do. This is for the Trusty release, but can be done for other dists by changing the offline repo script.

Lubuntu 14.04 still comes with the Synaptic Package Manager. After installing Lubuntu on your offline PC take the USB stick back to an online PC and run the below script. It will create an offline repository on your USB stick as outlined here: https://help.ubuntu.com/community/AptGet/Offline/Repository  It creates the necessary folder structure and gets all the info for 32- and 64-bit and also trusty-security, -updates and -backports. http://pastebin.com/mQU9Jy72

With this info on the USB take it back to the offline computer and add the USB repo to your sources list as outlined in the article. This can be done in Synaptic too, using
Code:
deb file:///media/<PCname>/<USBname>/us.archive.ubuntu.com/ubuntu trusty main restricted universe multiverse
After closing that dialog Synaptic will ask to reload the package information. You already should see some icons with arrows pointing up next to some packages, but close Synaptic for now, we'll come back to it.

In the file manager (PCManFM) go to the USB stick where you have saved the verified armory_*.deb, choose "Tools" -> "Open current folder in terminal" or hit F4. In the terminal "sudo dpkg -i armory_*.deb", this will throw some errors. Don't worry.

Open Synaptic again -> "Edit" -> "Fix broken packages". On the bottom it will show you how many packages need installing. In my case there were 44. At this point you can also choose to install additional packages if you wish, for example I find QtQR handy to work with QR codes. You also can choose to "Mark All Upgrades" to keep your offline system updated. When you're done, select "File" -> "Generate package download script" and save that in an empty folder on the USB stick as <yourscriptname>.sh

Take the stick to the offline machine. Before you can execute it, it needs a little change. The lines will look something like that:
Code:
file:///media/<PCname>/<USBname>/us.archive.ubuntu.com/ubuntu/pool/main/...
change that to
Code:
http://us.archive.ubuntu.com/ubuntu/pool/main/...
Easily done in Leafpad, using the "Replace" command. Replace "file:///media/<PCname>/<USBname>/" with "http://". Replace all.

Go to the empty folder and again: "Tools" -> "Open current folder in terminal". Type
Code:
bash <yourscriptname>.sh
Wait for the download to finish. Take the USB stick back to the offline PC and in Synaptic select "File" -> "Add downloaded packages". Point it to the folder and it will install the packages and finish the Armory install as well.

Armory (offline) is ready to use.

I am a US citizen who had more than $5000 USD stored in MtGox at the time of its collapse.
What action can I take right now to work towards getting my money back?

Citizenship is not important.  You should file a claim with the Japanese court-appointed liquidator, Mr. Nobuaky Kobayashi.  Links and information were posted in this thread a couple of weeks ago; look for "creditors meeting".  Some information is available in the MtGOX original website http://www.mtgox.com, but that site may still be managed by Mark, I dont know.

The deadline for filing claims was Nov/2014 but has been postponed to May/2015.  There is no date yet for when the spoils will be distributed.  Be prepared to get only 1/5 of your claim, at most.

You can't file claims yet.

The method for filing claims will be published on this site as soon as we are in a situation to announce it.
1054  Bitcoin / Bitcoin Technical Support / Re: downloaded BitCoin Core few days back, still downloading blocks. very slow on: September 09, 2014, 04:55:50 PM
your not connected to enough nodes
(think about it like torrents, if your only connected to 2 seeds you wont get alot of speed)

restart client or/and try adding some supernodes.

also i hope you got bitcoin-core from bitcoin.org and no other source as theirs rumours of altcoins pretending to be the legit bitcoin client which might be another reason

No matter how many nodes you are connected to you'll only ever download from one. If you think that one is slow, close Core, delete peers.dat in the data directory and try anew. Or if you know a fast node you can use the connect= command. For example 84.200.34.113:8333. I'm sure zvs will be present shortly with some more IPs you can try. Smiley


Edit: It also depends on your hardware's capabilities how long it will take to validate the block chain.
1055  Bitcoin / Pools / Re: [ANN] solo.ckpool.org 0.5% fee anonymous solo bitcoin mining for everyone on: September 09, 2014, 02:27:38 PM
Given the low frequency we're likely to be seeing blocks, I'll just post the found blocks here. I'm not even storing a share count or anything at the moment since shares mean nothing. We'll see if the popularity picks up and if I should add that in, but I suspect I'll mostly see a trickle of hashes from small hardware and the occasional failover.

If it's any indication (and you probably already know) one of the "competition" solo pool started last year November, reported 2.5 TH/s in February. It is now at 44 TH/s. They found their first block end of June and a total of 7 blocks since then.

Not quite sure what you are looking for, but QR codes with values (amounts) look like this for bitcoin:

1059  Bitcoin / Armory / Re: Armory - Discussion Thread on: September 09, 2014, 05:30:47 AM
On the other hand, I just leave Armory running.  Can use File-->Minimize to keep it hidden.  It shouldn't require much in terms of resources, and then is instantly available whenever you need it.  But I understand not everyone wants to do that (or might be resource-limited)

As yet another way, I have bitcoind (of bitcoin-core) in autostart. As it itself has no GUI, I won't even see it. The blockchain is always up-to-date this way, and whenever I run Armory, it's all ready in less than a minute.

How about a solution like amule / amuled? The daemon runs in the background and the GUI only connects when needed.

Sounds like your in the same boat I once was.

Your ebay link is what I meant for USB wallwart. A wallwart power supply with an USB port. I used one like those in my setup, it doesn't matter how much mA the output is on that one as long as there is "some" 5V. (As opposed to the RPi power supply that should be at least 1000mA, IIRC).


Judging from your pic it seems to me easiest, if you'd lay the hubs on the table so the plugs "hang" over the side of the table. That would bring the sticks upright.
