Here are some various sources I use in my day to day life.

Useful Research Tools

Mendeley - A free reference manager, much like Papers for OSX, but free.   

The Internet of Things

IFFT - I use this to automate a few processes.  I have found it to be mostly useful for exploring my photography

Pinterest - I have found to be useful of a few fronts.  From lesson plans for STOMP to interesting photography ideas and lesson, it is easy to get lost in the cool stuff you can find.
