Hints, table stats and the all knowing DBA

There was a brief discussion on adding ways to hint selectivity in #postgresql this morning. Often the database has trouble figuring out a proper plan for a given query. One solution to this problem is to let the RDBMS analyze the data in the table. But even that falls flat in some situations, even if it has reasonably up to date table stats. Maybe the effort is just too high to make it worthwhile to figure things out at runtime.

High Performance MySQL

I recently picked up two O'Reilly books for $20 each: "High Performance MySQL" and "SQL Tuning". I am almost done with "High Performance MySQL". Overall I would say it’s a good book. Not suprising from the original publication date it is focused on MySQL 4.1 and therefore does not cover a lot of the advances made with MySQL 5. Especially replication comes to mind, but also little things like index usage for MIN() and MAX(). It does however contain a few notes here and there about changes/enhancements to expect with MySQL 5.

I have been following the various wishlist items for PHP6 with quite some personal interest. I even compiled all the wishlist items I saw on mailinglists, on IRC or that were brought up at conferences and put it online. Much of these items made it on the agenda at the recent PHP6 core developer meeting in Paris.

Sorry, not interested

I am not interest in your software patent pledges. I want you to freaken burn them, I want you to freaken stop lobbying for this crap and I want you instead to lobby to ban their very existence. So I am very much in agreement with Florian Müller's (who has been working hard in cooperation with MySQL to prevent a legitimization of software patents in Europe) assessment of the state of affairs.

Sometimes you already have what you want

I wrote a reply to Chris Zend Framework wishlist. He focused on security aspects that by and large the WebBuilder2 framework has already effectively addressed. Since I was only made aware of this post today even though it was posted 3 weeks ago I am publishing it here as well to get some more exposure and more importantly feedback.
