Title: I'VE CHANGE MY MIND!
Post by: Peter Todd on February 23, 2013, 06:19:28 AM
THE MAX BLOCK SIZE MUST BE INCREASED TO AT LEAST 1.7MiB NOW!

This is why:

Code:
(bitcoind -testnet getrawtransaction 73e64e38faea386c88a578fd1919bcdba3d0b3af7b6302bf6ee1b423dc4e4333 ; bitcoind -testnet getrawtransaction d85af546147ff78dfb06e9469ddfc84adc3ce00cda54db8d65b7617ff2b7661a) | xxd -r -p | play -tul -

...also, for more sober experimentation, see block #54512, 0000000010bf4453b170a6756d911e207734ae181af6c8c02b42787d5885b333 and 54507, which seems to have broken blockexplorer.com/testnet

Can you explain this in more laymen terms of why it needs to be increased to at least 1.7 MB? Do you still support a fixed limit or is a dynamic one based on something possible?

Hahaha, awesome.  I'm convinced.

It's not something that can be explained, one must run the commands.

Who can reveal the secret to non-techies?

bitcoin radio, lol :)

update: I hope "play" is secure and there is no exploit there

Code:
-bash: syntax error near unexpected token `)'
-bash: play: command not found

Perhaps you should give a little more detail of how to execute this??
Also, do I have to d/l the whole testnet chain for this to work?

Suggestion: post a youtube of what happens!  8)

try
Code:
sudo apt-get install sox
(if you are using ubuntu) to install play utility

update: testnet blockchain is not that big, took several minutes to download

Been a long time since someone's gotten that by me.

You'll need app-editors/vim-core and media-sound/sox on Gentoo to get xxd and play, respectively:

Code:
emerge vim-core sox

If your bitcoind box is headless (like mine), you might replace the play invocation with something like this:

Code:
... | sox -t ul - -t wav foo.wav

Transfer this file to something that can play audio.

Yes.  Fortunately, the testnet blockchain only takes a few minutes to download at this time.
