 * Credential Management
 
 I use [[https://www.passwordstore.org/][pass]] to manage all of my passwords locally.  I also use [[https://github.com/DamienCassou/auth-password-store][auth-source-pass]] as the primary =auth-source= provider so that all passwords are stored in a single place.

 ** RSS with Elfeed
 
 [[https://github.com/skeeto/elfeed][Elfeed]] looks like a great RSS feed reader.  Not using it much yet, but definitely looking forward to using it to keep track of a few different blogs I follow using Twitter.  Also seems to be great for following subreddits like /r/Emacs.
