Want to contribute to your favorite CPAN module, or maybe create your own, but don’t have the foggiest idea how to do it? Here’s a few notes, tips, tricks and links that might help you get started.
Last month at the Boston MySQL User Group, I went through the meanings of INNER, LEFT/RIGHT OUTER, CROSS, NATURAL joins, how to do a FULL OUTER JOIN in MySQL, and what STRAIGHT_JOIN means. I also explained how to recognize when you want those types of joins, and best practices for the semantics of writing joins and design patterns. Subqueries were explained in this session, and some examples of how to think differently so that you end up writing JOINs instead of subqueries. The slides and video are posted here.

I’m so much looking forward to the next conference in my schedule — RMOUG Training Days 2010. It would be only my second time I’m presenting at the RMOUG but it was enough to go there once to understand that it’s one of the top rated Oracle User Group conferences in the world. Some of the great speakers are presenting and registration fees are very low compare to other events of comparable quality. If your conference budget is low this year — that’s the conference you don’t want to miss!
In light of the official Oracle acquisition of Sun, I dug out a presentation video I realize I never officially shared with either the MySQL or the Oracle community. It’s the presentation I did at the 2008 Oracle Open World conference called, “So, you want to be an Oracle ACE?” and is a good resource for anyone who wants to contribute to anything — not just Oracle or MySQL, though certainly it’s based on my experiences with contributing to MySQL. Have a look.
Happy Friday and welcome once again for news from the whacky world of IT. Big Thanks to Tim for pushing out last week’s edition. I was busy banging my head against a particularly nasty wall. If you think my head looks bad, you should see the wall.
Welcome to another edition of Blogrotate. This has been a busy week in the IT world. Here are some of the most interesting highlights.
Welcome to the 175th edition of Log Buffer, the weekly review of database blogs.
Oracle has just released their January installment of their critical patch update (CPU). Vulnerability CVE-2010-0071 is particularly critical, with a CVSS score of 10, the highest possible. It’s a remotely-exploitable listener vulnerability that’s particularly severe on Windows platforms. Full details are on Oracle’s security site.
Half the time I want to peek at the doc of a module, I hit perldoc. The rest of the time I type cpan Some::Module in Firefox and read the POD straight out of CPAN. And while it’s pretty and handy, it also feels kinda silly to go on a remote server to read documentation that is also sitting on my computer. Surely, I tell myself, there must be a better way. And here it is.
