1  Bitcoin / Electrum / Re: Can I update to 2.6.2 latest on: March 25, 2016, 06:04:11 AM
You can do it via command line.  This should work:
sudo pip install https://download.electrum.org/2.6.3/Electrum-2.6.3.tar.gz

This should install the new version over the old version and your wallet will be preserved and loaded by the new version.

I use Electrum as an offline wallet.

Instructions:
http://docs.electrum.org/en/latest/coldstorage.html

One nice feature is that you can make an online watch-only wallet without risking your private keys.

I just tried the Kivy showcase.  I have a similar issue for the drop down and spinner widgets there, but it's not as bad.  It only takes 1-3 presses to register a click.  So, yes, it seems to be a Kivy issue. 

Thanks.
I just checked the Kivy github page and the issue has already been reported (#4031).  I added my experience as well.

I just tried out the new Kivy version.  I've been looking forward to it for a while.  It's very impressive. 

Though I've run into a couple of problems:
1) I can't import a pre-2.0 MPK.  When I paste the key, the next button remains disabled.  It works fine with a post-2.0 MPK.
2) On my Galaxy Note 4, the menu pulldown is a bit flaky.  I have to press the menu item (About, Wallet, Settings) about a dozen times before it will actually register.

https://bitcoinfees.21.co/#delay says the fee you used was 10x too low. If you want to avoid problems use a fee of .0005 routinely.

I wouldnt suggest any fixed fee. The transaction may also be unusually large (in byte) for Erkallys which might be why they didnt have this problem before. You either have a wallet that can make a good suggestion or you have to rely on 3rd party estimates from e.g. 21.co.

I use Electrum, and that's what it automatically put as fee for me. Each time it put me this, each time it worked well, so I did not changed anything.

The default fee for Electrum is 0.5 mBTC/kB.  The fee you included in your transaction is 1/10th that.  I suspect you may have changed it at some point.
8  Bitcoin / Electrum / Re: Is the recovery key one factor access to 2FA or multisig? on: February 04, 2016, 02:05:26 AM
you can use the seed to recover your wallet .

Of course it's good to be able to recover without trustedcoin, but that's the point of 2-of-3 (compared to 2-of-2), and giving another party sole access to the third recovery signature.

Requiring both your private keys be in one place, as Electrum advises, seems to render multisig useless...

Right?


Who says you need both your private keys in the same place?  Split the seed in half and give half to a trusted friend.  You'll only need it for recovery. 

The local wallet only stores the first private key and it's encrypted.

Kuroth, your assumption is wrong.  I am a customer who has had several successful transactions and no problems.  I came to Coinbase after many problems with mtgox and am satisfied with the service so far, especially this past week, when many exchanges were have problems staying up.

Apparently other people have had problems.  I'm just not one of them.  I'm just trying to provide another prospective.  Your mileage may vary.
10  Economy / Service Discussion / Re: CoinBase now The Next Mt Gox????? BS on: November 22, 2013, 03:10:43 PM
I don't see anything walking like a duck here.

Have you tried withdrawing from coinbase?  When?  How long has it been delayed? 

11  Economy / Service Discussion / Re: CoinBase now The Next Mt Gox????? BS on: November 22, 2013, 03:03:11 PM
No, coinbase is not the next mtgox.  Not even close. 

This past week, all exchanges have been overloaded, and coinbase handled it pretty well. 

I sold some bitcoins on coinbase on 11/18 and the dollars showed up in my bank account on 11/22.  It took 4 days instead of the normal 2 days.  Not bad for one of the biggest trading weeks in bitcoin history.

Mtgox hasn't had reliable withdrawals for months.  If coinbase starts doing that then you can call it the next mtgox, but it's not even close to that.

Are you really charging 1% for all this, or did you conveniently forget to correct the OP on this point?

Are you expecting them to do it for free?

1% sounds really reasonable, its still 2% lower than paypal and CC's.

I think he was referring to the fact that bit-pay appear to be charging 3% for all of those service (according to the wiki). 

bit-pay.com mentions: "Processing fees as low as 0.99%", but I couldn't find what they charge for direct deposit in dollars.
13  Bitcoin / Bitcoin Discussion / Re: How do I merge my wallets? on: November 08, 2011, 01:42:11 AM
I believe you can do it with pywallet:
https://github.com/joric/pywallet

I've used it to import private keys into an existing wallet.

You can use it to dump the keys from the first wallet, then import the dumped keys into the second wallet. 

It doesn't appear to have been updated to work with 0.4.0 encrypted wallets yet, so use with caution.

The client does not need the entire database to work properly.  Future clients will allow downloading of only relevant blocks.

15  Bitcoin / Mining / Re: Hash/Share question on: July 18, 2011, 11:16:59 PM
I've been monitoring my hashing and shares more closely and it sort of dawned on me that Mhash does not necessarily translate into a share.  More clearly, X Mhash does not guarantee Y amount of shares within Z amount of time.  Is this correct?

example only: 100Mhash equals 1 share every second.  So 1 minute would always yield 60 shares


I've noticed some rounds, let's say under 2 minutes, I was not able to able to get any shares submitted.  But another, under 1 minute, I was able to get 6 shares submitted.




It takes on average 2^32 hashes to get a share.  So it takes roughly 10 seconds to generate a share on a 6970 (420MH/s).  This is a random process, so it will vary, but over the long term, it should average to 2^32 hashes per share.  So it would take about 4.2GH/s to average 60 shares per minute.

It will take on average "difficulty" number of shares to generate a block.

After every LP, I get 4-7 stales over the next minute:

Why are so many americans opposed to the metric system? The only primary numbering system taught in schools is base-10, so it's not like it's some weird foreign concept....

I mean no offense, I've just never discussed it before. And USA is one of only a handful of countries not using the metric system.

The USA is the only country not using the metric system.

I don't think Americans are opposed to it - they are just taught a different system.


That is false for two reasons.  The US does use the metric system for many things.  It is taught in school and used by all scientists and most engineers.  It's even used for some consumer products, though not very often.

Secondly, other countries use a strange mix of metric and imperial as well.  Namely England.  England uses miles per hours for road signs and stones for weight.  Yes, I watch Top Gear. Smiley

What's stopping someone from running off with your rig while your sleeping?

Looks like it's on the second floor balcony in a nondescript box.  Seems like no one would know it's there. 
19  Bitcoin / Mining / Re: 1200W PSU on: July 09, 2011, 10:43:38 PM
i purchased this one
http://www.microcenter.com/single_product_results.phtml?product_id=0357383

My friend had told me that a room only uses 1200W at a time, so I'd have to get a wire connecting to another room if i was to plug in anything else?? Sounds ridiculous to me, but i couldn't find anything about it online.

Most rooms have one or two 15-amp or 20-amp circuits though some older ones may be only 10-amp.  One 15-amp circuit can handle about 1800w.  If you have access to your circuit breaker, it should be listed there.

Not really true, it completely depends on how the electrician wired your house. THe electrician in my house obviously hated me, as literally every room in the house is split across two 15A circuits (the same 2), except the kitchen which has like 100Amps. And there's a 20A breaker that's connected to nothing.

THanks buddy  Roll Eyes

I was only speaking for the places where I've looked at the circuit breaker.  I didn't mean to overgeneralize, and I wasn't accounting for bad electricians.  My recommendation, before plugging in 10+ amps, you should check your circuits breakers.  I've had no problem with 2400w on a single 20-amp circuit.  YMMV.

One bad wiring job I've seen was an apartment I lived in several years ago in Allston, MA.  The whole 5 bedroom apartment had two 15-amp circuits.  If we used the AC and microwave at the same time, it would trip the breaker.  Even worse, both 15-amp circuits were connected to a old 20-amp fuse in the inaccessible basement.  So if we spread the evenly over the two 15-amp circuits, we blew the 20-amp fuse and had to wait til the next day to get it fixed.  Only made that mistake once.  Thankfully I didn't try bitcoin mining in that place.

Just out of curiosity, what motherboard and chassis do you use to fit 4 double-wide video cards?  Or do you use PCIe extenders?
