It is Sunday night and I’m sitting next to my wife Jasmine on the sofa in front of the TV. Jasmine is watching “Big Love” on HBO (a series about a guy who is married to three wives, poor guy!), and I have my laptop on my lap, trying to write some thoughts.
Well, I finally did it. I upgraded my blog to the latest WordPress version (currently at 2.0.2). And while I was at it, I also switched to a new WordPress theme. I hope you like it. I wanted to avoid changing the look of the blog, but the old theme was not compatible with WordPress 2.0. Moreover, I used a few new WordPress plugins, you can see all of them here.
Speaking of upgrades, take this simple example:
select nvl(nvl(nvl(null, null),null),4) from dual
What’s wrong with it? Well, having an “upgraded” database version, from 8i to 9i for example, gives you the option to write it like this:
select coalesce(null,null,null,4) from dual
Upgrades are good. But hey, upgrades are not as simple as they sound. Heck, I spent all Sunday afternoon and evening upgrading my simple and small blog. How long will it take to upgrade, not one, but multiple Oracle databases and make sure that nothing breaks in the process. Testing an upgrade is often the most time consuming part of the upgrade process.
