I didn’t take any photos myself at the MySQL User’s Conference. In reflection, perhaps I should. I did make it into some photos however. A few of them here.

Thursday’s Keynote speaker at the MySQL Conference was Mark Shuttleworth talking on The Ubuntu Project: Improving Collaboration in the Free Software World.

Ubuntu from Canonical Ltd is fastly becoming one of the most popular Linux Distributions, based on Debian. Here were some notes from his presentation. Mark had some really powerful one or two line slides that typified both his presentation intention and the goal of Ubuntu.

My talk at the MySQL Users Conference went well. MySQL For Oracle Developers was part of two talks, the second was by Mark Leith on MySQL For Oracle DBA’s.

My slides, like many talks just scratched the surface in the alloted. I’ve been working on additional reference material, a work in progress is available at …

Further to my earlier post Hacking MySQL Source (in a good way) in which I was having a compilation problem when re-compiling MySQL source (i.e. tt worked the first build, but failed on subsequent re-compiles, even with no changes).

By doing this, it also better highlighted the actual error, where previously is wasn’t. I didn’t keep a copy of the error, but in effect I needed to do the following in order to successfully recompile.

Everybody can contribute to the MySQL Open Source Community. Here are some ideas:

• You can start with completely a MySQL Conference Survey form (those forms that we are all avoiding).
• You can download, evaluate and test newer versions of MySQL Products.
• You can contribute to the MySQL Forums to ask questions and even give answers.
• Log Bugs & Enhancements on MySQL Products.

• Contribute your thoughts (via wiki), MySQL products, code snippets and …

At the MySQL User Conference - MySQL Quiz Show we were asked to Stump a MySQL Guru. Well I submitted a few questions, and the first one stumped the guru, being Jeremy Cole, and my prize was a MySQL tee-shirt.

Joe Kottke from FeedBurner in his MySQL Conference presentation today FeedBurner: Scalable Web Applications Using MySQL and Java mentioned a novel way of extracting SQL Select Statements from a MySQL Server.

The obvious MySQL ways include SHOW [FULL] PROCESSLIST, the Slow Query Log, and the General Query Log. In 5.1 you also use the INFORMATION_SCHEMA.PROCESSLIST.

Anyway, Joe mentioned he …

HackFest B: Creating a New SHOW Command by Brian Aker at the MySQL Users Conference

Brian stepped through the steps for those attending to modify and deploy new functionality in the mysql server. Cool. The end result I would consider for an experienced developer as relatively easy (after avoiding the pitfalls).

NOTE: I wasn’t able to complete this successfully during the session, but I’ve posted this, so hopefully the input and review of others can help in overcoming the current issues. See Outstanding Issues throughout my notes.

Our goal: Produce a new command SHOW CONFERENCE;

The following commands were performed on CentOS 4.2. There may be some …
