We organized our first OTN Developer Day: MySQL earlier this year in Santa Clara, CA, and the result far exceeded our expectation. Before we kicked off the seminar at 9am, the attendees had already taken every single seat in the beautiful auditorium in Oracle's Santa Clara campus, and there was still a line in front of the registration desk. We recruited MySQL experts from several teams to present, and had great questions and discussions along the way and at the end. I personally received many positive comments saying that the seminar …

Effective June 1, 2011, MySQL certification exams will be offered exclusively through a new test delivery partner — Pearson VUE — and will no longer be available through Prometric. This will consolidate all Oracle Certification exams within the operations of a single testing vendor so we can provide better service and global testing coverage for these Oracle certification exams. Pearson VUE currently has over 5,000 test centers worldwide in 165 countries.

To help prepare you for this transition, here are some important dates for you to be aware of:

• If you are currently following a certification path and are planning to take an exam on/after June 1: Registration has began at Pearson VUE on May 16, 2011 for all scheduled exams on or after June 1. Visit pearsonvue.com/oracle to create a new web account and get started.

Rapid Application Development (RAD) is a way of developing computer software applications with less effort than the traditional means.

RAD tools focus on providing code generation and automated testing capabilities with the use of convention over configuration to provide a streamlined workflow to create applications.

Even with the most advanced and easiest to use RAD tools, there are times which the traditional enterprise and the business software development vendors which are having their own implementations and in-house built frameworks are continuously refusing to adopt them.

Most of the misconceptions on the RAD are based on FUD (Fear, Uncertainty and Doubt) which has been created around the internal complexity of the RAD tools.

I get ask, by application developers,  “how do you optimize MySQL”.  I do lots of things that don’t really relate to a developer. I analyze the percent of queries are being pulled from cache for instance.  What a developer can do to optimize the SQL they develop is a different questions.   So here is a quick list of things applications developers should know about MySQL.

Explain will analyze your query.

This example shows the possible indexes (keys) that could be used and the index that was selected.  2,262 rows where selected and then sorted (Using file sorts) and one record was returned (limit 1).

mysql> explain SELECT 5/9*(temp_F-32) as t, 5/9*(dewpt_F-32) as td, speed_mps as spd, dir

UPDATE: The final vote is in and a winner has been declared, with Matt Asay and his arguments for the GPL taking the prize. You can see the debate or follow links to the other judges’ votes and thoughts here.

This is my assessment as a judge of the recent open source license debate held by the FOSS Learning Centre. We’ll have to begin with some qualifications and definitions, starting with the fact that there is no ‘best’ open source software license. Still, a star-studded open source software panel provided a lively, informative debate on the merits of some top open source licenses. For that, I congratulate and thank the panelists, Mike Milinkovich from the Eclipse Foundation arguing for the Eclipse Public License, Matt Asay of Alfresco arguing in favor of the GPL and David Maxwell from Coverity arguing for …
