precise explanation of Seconds_Behind_Master value
Thanks to Artem Russakovskii for this nice explanation of what Seconds_Behind_Master means
In order to see if a slave is lagging, execute the 'show slave status' command and look for the Seconds_Behind_Master value. The way this value is calculated can be slightly ambiguous and unclear, so I'll explain. It is simply a difference between the 2 timestamps the time of the last received (and queued up in the relay log) query that already executed on the master and the time of the currently executing query on the slave.
As he says in the post, this value is not a precise indication of the replication delay.

filtering planetmysql
If you follow planetmysql, you know that it is a torrent of useful information. However, it is like drinking from the firehose. To make it easier to follow planetmysql, I have created a yahoo! pipe which allows only posts with the words replication, scalability, bug, conference etc. or allows posts from certain authors (like Kaj, jpipes etc.).

converting text files to images
This question came up in one of the mailing lists I am on -
I want to take something which is an .html file, and turn it into an image. How do I do it?
Yes, you can take a text file and convert it into an image. Please put your hand together for the swiss army knife for image manipulation - Imagemagick.
You can use the convert command (part of imagemagick package) to do this. For example, I want to convert the file mysig.txt into an image. Here is how to do it
label:@mysig.txt ~/dump/mysig.png''For more tips on how to control the colors, font etc., check out the excellent tutorial at http://www.imagemagick.org/Usage/text/
