After yesterday’s success upgrading Gallery, I decided it was time to upgrade the Browncroft Neighborhood Association CMS. It was running Drupal 5.1, and I see from the Drupal web site that the currently supported versions are 5.7 and 6.1. So first I tried upgrading to 5.7, and that worked fine. Then I tried upgrading to 6.1, and that failed horribly. Fortunately, both times I made a copy of the site on a test address in order to try the upgrade, which allowed me to try a few different approaches.

The upgrade to 5.7 didn’t require all the stuff they always tell you to do, like turning off all the optional modules and setting your theme to the default. The second upgrade failed silently a couple of times until I did it by the book and *did* turn off the optional modules. And that’s when I discovered that the upgrade script failed on some “ALTER TABLE” commands, which makes me think that it was expecting a newer version of PostgreSQL than the one I have installed.

I note that Debian Etch has both PostgreSQL 7.4 and PostgreSQL 8.1 packages available. I installed 7.4 because it was the default. But from work, I know 8.1 has more “ALTER TABLE” commands than 7.4. So now I’m trying to figure out just how I go about changing my 7.4 installation to 8.1 without breaking Drupal, Gallery, and all my custom configuration. So, lazyweb? Anybody out there do that upgrade and know?

Whoever wrote the fucked up dependency checking in javac, and didn’t provide a way to turn it the fuck off.

I’m really sick and tired of having javac deciding that it needs to recompile something 3 directories ago in spite of the fact that both the jar file and the class file that it made about 3 seconds ago are in the CLASSPATH. This seems especially bad on directories that are NFS mounted, but if there is any clock skew between the NFS server and the NFS client, it’s less than a second and those source files haven’t been touched in weeks or months. It means that every time a low level class gets a new dependency, you have to modify the CLASSPATH in every fucking Makefile in the system because maybe, just maybe, javac will decide it needs to recompile that class for no apparent reason.

And don’t tell me “just switch to ant”. I have another rant building up against how ant and eclipse cause developers to forget everything they’ve ever known about partitioning of code and they start putting in calls to higher level stuff in low level code and causing circular dependencies.

The following software developers need a good swift kick in the balls:

• People who can’t let a boolean stand alone, and have to compare it to another boolean, as in "if (isOffline() == true)“. Why not be extra safe, and make that “if ((isOffline() == true) == true)“?
• People who don’t realize that after you’ve modified a value in a Map, you don’t need to re-add it back to the Map to have it take effect. “get” returns a pointer to the original object, not a clone of it.
• Eclipse (or maybe Visual Age) users who leave the code littered with comments that say “ * TODO To change the template for this generated file go to Window - Preferences - Java - Code Generation - Code and Comments" or Insert method description. Either configure the template, or turn off automatically generated comments.
• Anybody who declares a method to throw “Exception”, and anybody who calls methods that have explicit lists of what they throw, but who surround it with a “catch (Throwable t)” block. I don’t care if all you’re going to do is print the stack trace and continue, there’s no excuse for that sort of laziness.
• Anybody who changes huge swathes of somebody else’s code without asking the original developer if there is a better way. Especially if it’s code I wrote just a few weeks ago.
• People who use ‘do {…} while(cond);” People who use “if (cond == true) do { … } while (cond == true);” need to be kicked repeatedly.
• The entire staff of my company’s China office.

It’s inevitable that within seconds of posting to this blog, the new posting gets a trackback spam. Since the only other trackbacks on the blog are internal links between my posts, there doesn’t seem to be any point keeping them. So I’ve turned off the ability to do trackbacks. Sorry, spammers.

I’ve had a series of bad experiences with cheap-ass external USB drives. I’ve bought some that sucked right away, and some that look like they’re working right at first but which get slower and slower and slower. One I have now that I’ve had for years is working perfectly, and another transfers a few files quickly and then bogs down hugely and gets slower than USB 1. I’ve also got a couple of Seagate Free-Agents that are working perfectly (after I discovered how to turn off sleep mode).

So I’m thinking that from now on I should stick to the known brands. Also, my backup needs are getting bigger, so I’m thinking of getting a 1Tb disk. Does anybody have any specific recommendations in that size range? Stick with Seagate? Right now the price leaders seem to be Iomega (the company that brought you the term “click death”) and LaCie. Any experience with them, especially as TimeMachine drives or doing hourly rsync backups on Linux?
