It has been a few busy months until now. I have moved from Italy to Thailand, and the move has been my first priority, keeping me from attending FOSDEM and interacting with social media.

If you have a capable programming language at your disposal (Perl, Python, Ruby, PHP, or Java would fit the bill) you can code a test that sends several transactions in parallel.
But if all you have is the shell and the mysql client, things can be trickier. Today I needed such a parallel result, and I only had mysql and bash to accomplish the task.!-->!-->

Of the following snippets, which one will run 10 times?!-->!-->
The call for participation for Percona Live MySQL Conference 2014 is still open. As part of the review committee, I will be looking at the proposals, and I hope to see many interesting ones.!-->!-->
