OS X upgrade recovery

Once OS X server is upgraded, TreeTapper no longer connects to a database because php it is using no longer has postgres support. The solution:

• Install macports (probably already done)
• sudo port install php5-postgresql
• cd /usr/libexec/apache2/
• sudo cp libphp5.so libphp5.so_ORIGINAL
• sudo cp /opt/local/apache2/modules/libphp5.so . [note the period]
•  Restart apache (aka turn off and turn on the web in Server Admin)

An OS X upgrade moves apache back to its base settings, apparently.

Firebug debugger

Treetapper will be fairly Ajax-rich (though with more RESTful interfaces, too, and with concern for accessibility). I didn't know any Javascript (or PHP) when starting, so having a good debugger is handy. I first tried a "Javascript Debugger" plugin for Firefox, but it seemed a bit clunky. I've now installed Firebug, and I am so far quite happy with it. It allows debugging/inspection of the Javascript, CSS, and HTML of the page.
