"A simple way to spread goodness": "George Washington Carver said, 'How far you go in life depends on your being tender with the young, compassionate with the aged, sympathetic with the striving, and tolerant of the weak and the strong . . . Because someday in your life, you will have been all of these.'

Frequently Asked Questions: "Question: Why are you using 'StringBuffer' instead of 'String' for passwords & text?
Answer:
Starting from beta 6, I've changed all passwords and text containers from Strings to StringBuffers.
The Java Virtual Machine uses a garbage collector (GC) to cleanup memory. In Java we don't have functions to clear the memory. In fact, it is possible that the GC is not called after an operation and that some (sensitive) information stays in memory. So we have to cleanup our 'mess' by ourselves.
In Java, Strings are immutable, they can't be changed after they were set. Even if we set the string to null and the GC is called it is not sure that this information is cleared from the memory. With StringBuffers or character arrays we can resize and reset data byte-per-byte. This is what I did, cleanup the StringBuffers after usage, so we are sure that sensitive information such as passwords are stored in memory only during the time needed (as less as possible)."
Intel Macs will run Windows... eventually:
You, this will be so sweet. I need to check out the Virtual PC for Mac OS X
"So Mac OS X and Windows will still run natively on Macs, but we'll have to wait for Windows Vista to see it happen. Once Microsoft ships a version of
Virtual PC for Mac OS X compiled as a Universal Binary,
Mac users will be able to run Windows at near-native speeds on their machines."
FAQs: JTA: "Can I use more than one non-XA connection pool in distributed transactions?
No. Even if you set EnableTwoPhaseCommit=true for both TxDataSources of the connection pools, attempting to use two non-XA connection pools in the same distributed transaction will result in:
'java.sql.SQLException: Connection has already been created in this tx context for pool named {first pool's name}. Illegal attempt to create connection from another pool: {second pool's name}'
when you attempt to get the connection from the second non-XA connection pool."
