Why don't the 5 biggest mining pools (ghash.io, btc guild, eligius, slush and bitminter) publish what transactions they are including in the block they're mining? (The transactions that will be included in the next block if they mine it) That way you could be relatively sure that your transaction will (probably) be included in the next block. If you're a merchant, you can be reasonably sure there won't be a double spend, if all 5 of them include the correct transaction. (If some of them have a conflicting transaction you know that a double spend was attempted). This seems like a really useful feature. Why don't they provide it? I know that they publish the block headers to connected miners, but not the list of transactions.

I wanted to install BitMessage. It had a lot of dependencies.
I had to install XCode command line tools, gcc, cc, clang, homebrew, macports, python 2.7.5, qt, pyqt, and openssl. That took about 3 hours. Now I hate makefiles with all my soul and being.
Anyways, I got it all installed, and this happens:

 PyBitmessage requires PyQt unless you want to run it as a daemon and interact with it using the API. You can download PyQt from http://www.riverbankcomputing.com/software/pyqt/download   or by searching Google for 'PyQt Download'. If you want to run in daemon mode, see https://bitmessage.org/wiki/Daemon

What does this mean? How do I fix it? I definitely installed PyQt. The file /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/PyQt4/QtCore.so exists, it has random symbols in it.
*edit* Looking through the QtCore.so file, I can see "qpycore_pickle_protocol" on line 26,653 and 30,960... *edit*

We all know his address, right? 1BitcoinEaterAddressDontSendf59kuE
I want to make one of my own. (I mean just make a public key with the correct checksum)
How do I make the checksum work?

In the future, when transactions start to compete in blocks, what algorithm(s) will/should miners use to optimally determine what transactions they should include to get maximum transaction fees while keeping the block size below 1MB?
