Bitcoin-Qt / bitcoind version 0.8.0 released

Remember when Computer Shopper used to be the size of a phone book in a major metro area?

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

xubuntu-desktop or lubuntu-desktop will work too.

Sometimes they would just publish the binary, as a hex dump, and you had to type in the hex characters.  That was really painful.  At least while typing in source code you could get an idea of what was going on.  But hex just looks like hex...

I remember handing stacks of IBM punch cards through a window to a computer operator in the inner sanctum.
Each card contained one line of Fortran IV source code.

Software wasn't for woosies back then.

Too bad bitcoin-qt can't use your GPU to accelerate re-indexing the block chain.  It's already using multiple CPU cores if they're available.

I don't think GPUs lend themselves to ECDSA validation very well. It's an interesting idea, though.

What is causing this ? I'm having a hard time to get 0.8.0 up to date. Win7 32. 2 PCs, same troubles. 0.7.2 was working flawless.

Your problem seems almost identical to what I'm experiencing on my second PC. The computer itself works quite fine but I've still been completely unable to get 0.8 to sync till the end successfully. I've had corrupted blockchain and wallets, and the latest try resulted in similar errors that you posted, somewhere around 3500 blocks left. With 0.7 I had no problems.

On this PC however, I've had no problems with 0.8.

i dont know about causes but it was vary slow going for me. especially the last 10%(which i didnt have to begin with) i also had some kind of error while downloading when i had around 3000 blocks remaining. the client just stopped downloading them. the progress bar vanished, it still showed on the bottom right that it still had more to go and the client itself still showed i wasnt fully up to date. i had to close the program and reopen it to get it to continue where it did eventually finish, i wasnt paying attention to download time, but it was hours.

to be clear, reindexing was clearly fast, but downloading new blocks is just as slow as it has always been. and it would have been nice if the program deleted the old blocks or at least gave some info as to why it was using so much disk space. in the end i just ended up moving the old blockchain files to see if it would work without them. when it did i just deleted them. if i had to go back a version for some reason i would have just re downloaded the blockchain, no big deal.

I send 20btc today from Bitcoin-Qt without selecting any fee but i saw in blockchain info that a fee of 0.01000022 has been issued!
is this a bug or something else? should i set a default fee? how low?
Also it could be great if we are able to select the address that sent btc from.
The client just use all my available addresses!

blockchain.info grossly misrepresents how Bitcoin works in various ways.
Please check your client to see the actual fee (double-click on the transaction on the Transactions page, if there is a fee it will show "Transaction fee: x BTC" - if it doesn't show this exact line, there was no fee paid).
Bitcoin does not have "from" addresses.

[luffy]

thanks Luke junior :p
indeed no "fee" line exists in transaction details!
for one moment i was afraid that bitcoin network start using fees by its own

can you remember the smell of paper tape?

I remember my Dad used to bring rolls of it home from work and we'd make Christmas decorations out of it.  I remember starting to decode a tape one time, looking up the ASCII codes one by one and hoping to find official secrets or something.  I gave up after "10 REM STAR TREK GAME" or some such.

LOL.  Looks like you did.

Long-time user, here.  Just launched 0.8 for the first time.  I have the setting made to connect through proxy only (Tor).  The new client inherited that setting from previous installations.  I FORGOT to launch Tor, but the blockchain is downloading anyway.  

If I am not mistaken, this means it is connecting to the network, ignoring the proxy checked setting.

UPDATE:  It stopped syncing at 26 days left.  So maybe the bootstrapped portion of the block does not go through proxy?

The reindex comes off your hard drive (previous version's data).

Thank-you to all involved for your continued hard work and development.

During the upgrade if we want to pause it (e.g. to get some work done), what is the best way to do that?  I'm running on Ubuntu 12.04.

E.g. I ran "bitcoind -daemon"  (I wish I could leave that daemon running and have bitcoin-qt reference it....)

Is it safe to do a "bitcoind stop" in the middle of the upgrade?  Will I lose any work already done?

Or should I stop the process in mid-stride (kill -stop <processid>) and kill -cont it later?

I'd say both are safe.

[phatsphere]

I wouldn't do that, because if "something happens" this is equivalent to a crash. some pages before I did do some -9 kills and it corrupted my wallet and bitcoind didn't start any more. so, to be on the safe side, shut it down
