The default Postgresql installation on Mac OS X using homebrew includes a single extension - plpgsql (PL/pgSQL procedural language) but there are a number of them available in the lib directory (/usr/local/Cellar/postgresql/9.2.1/lib on my machine)

To install an extension into the database, the easiest way I found was to open a database console using the 'rails db' command and then create it directly. I have seen mention of doing this in a Rails migration but this did not work for me.

Note that an extension is installed in a specific database, rather than being added to all databases.

The command to list the installed extensions is '\dx'

$ rails db
psql (9.2.1)

Using netcat and ssh tunnels, create a shared clipboard allowing client and server clipboards to be fused

Serve pbcopy and pbpaste on Mac's localhost

NOTE: That we are making the assumption that the clipboards are sending and receiving UTF-8 encoded bytes

From https://stackoverflow.com/questions/18215389/how-do-i-measure-request-and-response-times-at-once-using-curl

cURL supports formatted output for the details of the request (see the cURL manpage for details, under -w, –write-out ). For our purposes we’ll focus just on the timing details that are provided.

Create a new file, curl-format.txt, and paste in:

    time_namelookup:  %{time_namelookup}\n
       time_connect:  %{time_connect}\n
    time_appconnect:  %{time_appconnect}\n
   time_pretransfer:  %{time_pretransfer}\n

class PasswordsController < Devise::PasswordsController
  # here we need to skip the automatic authentication based on current session for the following two actions
  # edit: shows the reset password form. need to skip, otherwise it will go directly to root
  # update: updates the password, need to skip otherwise it won't even reset if already logged in
  skip_before_filter :require_no_authentication, :only => [:edit, :update]

  # we need to override the update, too.
  # After a password is reset, all outstanding sessions are gone.
  # When already logged in, sign_in is a no op, so the session will expire, too.
  # The solution is to logout and then re-login which will make the session right.
