1  Economy / Trading Discussion / mtgox and yubikey order on: March 25, 2012, 10:12:20 AM

I've just ordered a yubikey from mtgox with a discount coupon code, but can't find any verification in either of the USD or BTC finance pages. Should it show up?

I've got a screenshot of the confirmation page anyway.

2  Other / CPU/GPU Bitcoin mining hardware / RaspberryPi raw hashing speed for SHA1/256/512. on: March 07, 2012, 10:49:47 AM

Since a number of people were asking about mining performance on an ARM CPU used in the Raspberry Pi.

This is raw hashing speed on an rPI, This should be halved for bitcoin mining; no idea how it translates to litecoin.

Obviously this is not a test with mining code, and not tested with the performance optimizations that could be achieved through the likes of ARM native code instructions or other mining hashing tricks.

still trying to find whether it is an alpha or beta board that the test was run on.

3  Bitcoin / Bitcoin Technical Support / Missing transactions, tx notification at client and pending. not seen on: February 17, 2012, 09:10:01 AM

I used electrum  to send 0.7btc with 0.001tx fee to 18eMSCd46uZRv6oJEMmtP8s7XxWuHQjLEG, on 16/02/12 the middle transaction is the relevant one (though the others are also 12hrs+ pending - the top one 08/02/12)

pending   0279a7f63da25e580e2a4f2d0f03a39f4d411685042fedda5bf9402c51213d1e     -0.01           
pending   f56ebf88b179dd8511acff34ec1635cfdad13f834f18f2075dd4cbcd8863a0db     -0.7005         
pending   b78731816efac7a773261dfe25aa6a9e2949a80ff428d3d51ff39d5faceb4777     -0.0001         

yesterday had the middle tx listed as 0.7 with unconfirmed transaction, now it has no tx found on the network.

my bitcoin client that is supposed to be receiving the transactions still shows pending for the first two transactions, again doesn't  have it on the network. How can my client have been notified of the transactions, and blockchain not show them.

What is going on?

4  Economy / Lending / Looking to borrow 10BTC for 5 days. on: February 10, 2012, 12:49:34 AM

I'm looking to borrow 10BTC and will pay back 11.5BTC.

If possible I would like an option to roll forwards for another 7 days, after making a preliminary repayment of interest.


5  Bitcoin / Electrum / Electrum created a negative balance - rounding errors on: February 04, 2012, 07:32:36 PM

I had 0.006btc and sent out 0.0059 with a 0.0001 tx fee to create a 0.00 balance. The 0.006 was built with 6 0.001 transactions.

The transaction is now 7 hours STILL awaiting confirmation.

please explain how to get confirmed transaction and from the following....

>Electrum-0.35-Build1.exe history

pending   62d4b6 ...  -0.006000   -0.000000
# balance:  -1.73472347598e-18

I think there are some rounding errors somewhere within the code.

6  Other / Beginners & Help / new wallet, only 1 tx of 0.001BTC and now I have 0.004BTC. How? on: January 08, 2012, 01:11:40 PM

Using the bitcoin 0.5.1 client, with a new bitcoin datadir and blockchain I had 0.001BTC sent to one of my addresses, and there are no other transactions.

The client shows 0.004 for that transaction.

The client shows no other transactions.

pywallet -dumpwallet shows no other transaction.

Blockexplorer shows the address as having 0.001BTC.

a -rescan does not change this. What do I actually have and how can I find out? I'm running on Windows.
