Ubuntu Hardy + Firefox + Firebug

The old firebug is not working for firefox 3 beta 5 in Ubuntu Hardy; and so firebug 1.1 from the official site.

Solution: get the 'firebug' package from apt. :)

mod_rails + edge rails

Based on a recent conversation at phusion passenger google group, there is a bug wherein mod_rails fails to start its spawner for an application that uses edge rails.

Basically, you'll get this error (complaining about a failed 'to_constant_name' somewhere):

  Framework that failed to load:
  Vendor directory: /path/to/vendor/rails
Error message:
  Anonymous modules have no name to be referenced by
Exception class:
  ArgumentError

More info about the bug can be found in the bug report filed by hongli


update: This seems to be fixed in edge rails + git passenger (though I havn't tried yet), as hongli's comment below says.

mod_rails + rails 2.0

I you encounter a "500 Internal Server Error" after setting up mod_rails in a recent (rails 2.0) application, you need to delete 'public/.htaccess'.
