The call for participation for the MySQL Users Conference and Expo 2009 has been open for a month, and it will last for a few weeks more.

The CfP is open until October 22nd, 2008. The theme for the conference is Innovation Everywhere. If you have something innovative in mind and want to submit a proposal, hurry up!

Before you submit, make sure you read the guidelines. That will help you making a better proposal, with more chances of being accepted.

The good: row based replication solves some problems when replicating the result of non deterministic functions, such as UUID() or NOW().
The bad: row-based replication may break existing applications, where you count on the quirks of statement based replication to execute conditionally (updates base on @@server_id, for example), and may perform badly on updates applied to very large tables.

In the previous post we had a look at the MySQL Cluster NDB API and how it enables direct access to the MySQL Cluster data nodes, and therefore also enables access through other protocols than SQL.

I've often asked myself: Since NDB is so great for MySQL Cluster, is there anything similar for MySQL Server (the not-cluster version...)? A couple of months ago Kazuho Oku did something like that and wrote in his blog about it.

The context for Kazuho's work is the social network use case: 1) You have users. 2) Some users are linked to each others as friends. 3) When a user logs in, he should see a timeline of events/messages from his friends. In a previous post he had already tested the difference between a …

The current US financial situation has claimed a victim in the Web 2.0 world — Uber. I’m not sure if this is the first significant name, but it will not be the last site running MySQL where investors will be quick to cut losses and move on.

At OOW, I ran into Stephen Feuerstein after seeing him demonstrate Quest Software's "Quest Code Tester" product. Considering how I might use a product like that for testing web-based applications, I suggested a couple of enhancements.The biggest, most important procedures that I test in PL/SQL are those that generate entire web pages. For that kind of testing, you can't look at whether data has

Roland Bouman and I will be doing a presentation together at T-Dose on October 25th:

Building Open Source BI solutions with Pentaho and MySQL

It’s a free conference, feel free to join us there for a chat and/or a drink!

Until then,

Philip Stoev, Software Engineer

The mission of the System QA team is to beat the living daylights out of a MySQL release before it is set free into the world. Philip Stoev is on the System QA team, not the Falcon team, but bless his Bulgarian heart, he's caused more trouble on Falcon than anyone in recent memory except for perhaps Peter Z.

The "trouble" of which I speak is best illustrated by this vignette: Imagine that HMS Falcon is on a shakedown cruise in the Mediterranean. Weather is clear, crew is happy, course is plotted. Midshipman Stoev voices a concern.

"I beg your pardon, Captain, but I believe the ship has run aground."

"Nonsense, Mr. Stoev. The ship is quite sound. She floats upright, the sails are full and the crew is happy with rum and song. "

I have been researching Business Rules, Decision Trees and Decision Tables and how they can be used in a relational database for some time. I decided to write a Wikipedia article about a new software development methodology I call "Decision Table Driven Development".I believe its a good idea, but then again, I am biased. 

I am new to wikipedia and recently learned that I need to move my writing style away from "my opinion" to "concrete research". I already got a notice that I have 4-5 days to improve the article or it will get deleted :(
Its still a work-in-progress, but if you would like to read it, comment on it or ask …
