  • Sqlite database keeps collecting cruft as time passes, which can be cleaned by the 'vacuum;' command. This command cleans up the cruft in all sqlite files relating to the user you have logged in as. This command has to be run when firefox is not running, or it will exit displaying the pid of the firefox running.

  • Filters out all non-insert SQL operations (we couldn't filter out only lines starting with "INSERT" because inserts can span multiple lines), quotes table names with backticks, saves dump to a file and pipes it straight to mysql. This transfers only data--it expects your schema is already in place. In Ruby on Rails, you can easily recreate the schema in MySQL with "rake db:schema:load RAILS_ENV=production".
