Free Hadoop class in Dallas
Cloudera Instructor Tom Hanlon will be presenting a free class on Hadoop Tuesday March 15th on Dallas. Tom is a familiar face to MySQLers in the North Texas area having previous taught many MySQL classes. 
Pizza and Drinks will be provided.
This will be an excellent opportunity for MySQL DBAs to learn from booth a MySQL and Hadoop expert. Hadoop is a computational paradigm named Map/Reduce, where the application is divided into many small fragments of work which may be executed any node in the cluster.
Register Here as they may need to shift locations to find the anticipated crowd.

When did that statement finish?
A friend wanted to go to lunch but need to time (roughly) how long a UPDATE took on one of his instances. 
The friend had a co-worker who said the statement would take X time and the friend was pretty sure it was X/2. Me? I was hungry.
I edited the ˜.my.cnf and added the following:
This changes the mysql client prompt from mysql> to 11:42:22am>. The friend started the mysql client, entered the query, and we went to lunch. We when returned, there on the prompt line was the time the command finished.
An old simple trick but it did what was needed. The documentation on the prompt string details more options. I probably would not want to use this trick for more than the crudest of benchmarks. I do use something similar to display the hostname when dealing with slaves in replication.
