When pasting ActiveRecord::Base.logger = Logger.new(STDOUT) into the rails console, it will convert all active record queries into raw SQL.
This is helpful to make sure active record queries are optimized (avoid n+1) or quickly grab an SQL statement for database software.
A great tip to keep in your back pocket!
Today Nicolas Goutay, a colleague at Orbit showed me how to turn a webpage into design mode. This can help show requested changes to co-workers by editing the page and taking a screen shot, or just to have fun changing pages as you would like.
Head to the console of the webpage you would like to edit, and type document.designMode = "on" and start editing the text on the page!
Have fun!
