https://exchange.bitparking.com uses Google authentication.

On the flip side of security it is less secure for users - your gmail gets hacked, bye bye Bitcoins everywhere. It also trains users that it is okay to put their Google password into the web browser when they didn't specifically type google.com.

Here is a transaction that was one Satoshi for input, one Satoshi output and obviously then, no fee.
 - https://blockchain.info/tx/1064fedccbb1225d6879c79a58e59cda795d4023da140f2ad0bc4c189e5e373f

It never made it into a block.  It was sent via Blockchain.info/wallet I'm told.  It doesn't have an invalid input (double spend), so I would presume the Blockchain.info back-end bitcoin daemon would keep trying to re-broadcast the transaction with it not being included in any blocks.  

Then recently that transaction output was used in a new spend transaction:
 - https://blockchain.info/tx/bfe3df19956eabd8c1b87bf1cde1a1526abb80a9bf3320ee838c05edd4a1138f

Of course, this new transaction won't confirm because one of the inputs hasn't confirmed.   But since that earlier transaction isn't still being re-broadcast (persumably, maybe it is but no nodes it is connected to will relay it) then no miners will ever include the earlier transaction and this transaction will never confirm as well.  But that leaves the Blockchain.info/wallet user stuck -- the Blockchain.info/wallet see those 512+ BTC as being spent and won't let the user spend them in a new transaction.

What methods to resolve this are available?

[Edit: Here's the thread with the request for assistance:

512 btc in a transaction that will never confirm, need help
 - http://bitcointalk.org/index.php?topic=147519.0 ]

just a correction, the transaction 1064fedccbb1225d6879c79a58e59cda795d4023da140f2ad0bc4c189e5e373f was not sent through blockchain.info wallet. This transaction is an automatic transaction that an address created with http://blockchain.info/api/api_receive sent after receiving this satoshi from other transaction.

This could be avoided if blockchain.info would only count towards your balance confirmed inputs, like the reference client does. This would spoil the fun of gamblers spending long chains of unconfirmed transactions though.

The user is also waiting on a transaction that was sent from blockchain.info without the minimum per-kB fee.

Just for gits & shiggles.

I just picked words likely to be associated with Bitcoin. I had some candidates like 'gavin', 'zhoutong', etc., that I removed because that would focus on a less known entity. I only see two organizations in the word list (although you could put together some words to make a few more organizations or partial organization names, I guess).

Sorry, no correct answers yet.  wah wah wah.

Big Hint #2 - The answer wouldn't be different if I used lower case letters instead of upper case, but the clue would only be one letter!

Just for fun! Find the Bitcoin-related words by printing the image out on dead trees and circling, or just open the image in a paint program and draw lines through the words you found.

How many (of 47) words can you find in five minutes? Expert level - without knowing the words your searching for?




Word List (highlight to spoil the fun:)

address, asic, balance, bfl, bitcoin, block, btc, cash, cent, chain, coins, confirm, crypto, difficulty, escrow, exchange, fee, forex, fpga, generate, gpu, hash, input, key, merkle, miner, money, mtgox, network, nonce, orphan, payment, peer, pool, private, reorg, reward, satoshi, script, send, shop, sign, socks, spend, sync, transfer, wallet

how about BZZZZ! You can share your thinking about your wrong answer though. I'll give some time before I give another hint; this is a Mensa-style puzzle that came to me during the course of doing some work.

All the information needed to complete the sequence is contained within the letters, you don't need to Google anything, just use your noggin. There is more than one letter required to complete the sequence though. The 26 English alphabet letters are used, not a foreign language.

PS.  May I ask what font that is?

[Collected on the Internet, 1994]

I heard it as a joke story told more than three decades ago in Germany, regarding an auto mechanic. A customer required a nut fastened somewhere on the car. Complaining about the 25.00 DM bill, he gets this itemized list from the mechanic:


Nut.50 DM
Gewistwo24.50 DM

Gewistwo is dialect in that part of Germany for "Knowing where . . .")

What exactly does "crooked" mean?

If someone PwnD your computer, they also can have control and access to anything on it and anything you type.

But isn't that a risk with any computer?  Why would this be a bigger risk?

Because we assume that you use your normal computer for doing things like clicking links like these (any of which could infect your computer with no input from you). Any virtual machine or encrypted sub-system that you run on your system is just as vulnerable since the remote attacker will have the same privileges as you on the main OS.

A USB boot drive is a more secure environment, especially one that comes with no web browser. You install it clean off a LiveCD as I describe above, so it is never potentially tainted. You only type it's password directly into the USB boot OS. The data can be made unreadable by anything other than the boot code on the USB. It's kernel can be firewalled to only accept incoming Bitcoin connections and nothing else.


With one of the larger manufacturers making it (Sandisk, etc) people would trust it.  
Assuming that a manufacturer made purpose-built Bitcoin device is automatically better is wrong. I wouldn't trust anything with software loaded up in a Chinese factory with my money, especially a device they know will contain my money.

If you placed your virtualised tiny linux wallet in a trucrypt hidden volume, it doesn't need to go on any fancy usb stick - as long as its big enough for the blockchain?

http://www.truecrypt.org/hiddenvolume

its going to take longer to write a decent pass phrase than the time needed to set this up Wink

Maybe I should write a tutorial? Wink

Mining != anything in this thread. There is BAMT for that.
1558  Bitcoin / Bitcoin Discussion / Re: USB Selfbooting Solid State Wallets - Secure - Manufacturer Needed! on: February 26, 2013, 11:42:10 PM
This can be done now, you can boot off tinycore linux liveCD (12MB). For v0.8.0, install qt-4.x-base through "apps", wget http://iweb.dl.sourceforge.net/project/bitcoin/Bitcoin/bitcoin-0.8.0/bitcoin-0.8.0-linux.tar.gz, and tar xvf bitcoin-0.8.0-linux.tar.gz.



It will explode after you use up it's 1GB RAMdisk downloading blockchain though, so you install it to a 32GB flash drive, and you can now boot a full OS with full GUI Bitcoin off removable disk. You can encrypt the home directory so Bitcoin data is unreadable without booting and entering a password.

I could easily make such a thing preloaded with blockchain for sale, the trick would be convincing others it is trustable and that future ones I sell would remain trustable.
1559  Bitcoin / Bitcoin Discussion / Re: Bitcoin-Qt / bitcoind version 0.8.0 released on: February 26, 2013, 11:07:22 PM
I'm running Ubuntu 12.04, all upgrades applied, in a VirtualBox.  Almost all networking is IPv6.  The VirtualBox has 512 MB (<--small, I know) RAM.
The host machine is a dell Optiplex GX620, XP-SP3, 4 GB ram, 3.00 GHz pentium 4

I created a new virtual machine, created a disk specifically for bitcoin, and mounted it on ~/.bitcoin...


Congrats on running a 11 month old OS, on a 11 year old OS on a 10 years old computer (P4 3.0GHz release April 2003). There weren't many people trying to use a 1991 computer (pre CD-ROM) in 2001 (post-Google).

Is this progress or a lack of progress?



I'm running Ubuntu 12.04,
One thing I notice is that the menu (File, Help, & such) does not seem to display if the program is shut down, and then restarted.  If the window is maximized, these items show up again.


You are not the first to report strangeness with Unity (the bastard pile of MacOS wannabe move-the-menu-to-the-top bs that Ubuntu slapped on Gnome in order to keep up with Windows 8 in the stupidifying of GUIs). There is an official issue here: https://github.com/bitcoin/bitcoin/issues/1242 where you can add your steps to replicate on 0.8.0.

The workaround is sudo apt-get install kubuntu-desktop.

Oxford English Dictionary definition of "money"

noun
A current medium of exchange in the form of coins and banknotes; coins and banknotes collectively:I counted the money before putting it in my wallet; he borrowed money to modernize the store
  • (moneys or monies) formal sums of money:a statement of all moneys paid into and out of the account
  • the assets, property, and resources owned by someone or something; wealth:the college is very short of money
  • financial gain:the main aim of a commercial organization is to make money
  • payment for work; wages:she accepted the job at the public school since the money was better
  • a wealthy person or group:her aunt had married money


Definition of coin
noun
    a flat disc or piece of metal with an official stamp, used as money

Definition of banknote
noun
    a piece of paper money, constituting a central bank’s promissory note to pay a stated sum to the bearer on demand: a £100 banknote


Is Bitcoin a medium of exchange? True
Is Bitcoin in the form of a flat disc or piece of metal? False
Is Bitcoin a central bank's promissory note on paper? False
= Therefore, is Bitcoin money? No.

However:
-By the above definition, a medium of exchange that is only coins or only banknotes is not money. Therefore the currency of Laos is not money - they have no coins.
-Does the definition "a central bank’s promissory note to pay a stated sum" even make sense? No. A promise to pay you what you already have is a circular reference.
-By the above definition, a bank account does not contain money - computer balances transferred from other computer balances are not coins or paper. However, the below definition states that a bank account does contain money:

Definition of bank balance
noun
    the amount of money held in a bank account at a given moment

Since the definition of money, in the most authoritative work defining word meanings in the English language, does not correlate with even the simplest concepts and usage of money today, and is in contradiction with itself, we must therefore extrapolate that the definition of money can expand to new mediums of exchange beyond coin or paper or that issued by a central bank, to anything that shares the collective concepts associated with money.
