In rails applications development.log and test.log like to grow forever, which takes up space and makes them slow to grep. If I just delete them running processes with logs open might get confused. So I can use truncate instead:

   1  
   2  truncate ~/www/*/log/*.log

Even easier, ask cron to do it for me every night:

   1  
   2  4 22 * * * * truncate -s 0k  ~/www/*/log/*.log

I tried to use this method here: http://snippets.dzone.com/posts/show/3264 however my typo blog was too slow and it kept timing out (which is why we're switching to wordpress anyway...). So I stole the code and hacked it up a bit so it could be run as a script.

Put this in $RAILS_ROOT/script/wp_export.rb, and run it like:

   1  
   2  RAILS_ENV=production ./script/wp_export.rb > out.wxr

Import it with the "Import Wordpress" tool in your wordpress blog's admin interface.

   1  
   2  #!/usr/bin/env ruby

   8  # we need a controller to generate html output
   9  class FakeController < ApplicationController
  10    include ActionView::Helpers::TextHelper
  11    include ActionView::Helpers::TagHelper
  12  end
  13  fake_controller = FakeController.new
