Jim Baker - A Winning Strategy with The Weakest Link: how to use weak references… - PyCon 2015

"Speaker: Jim Baker
Working with weak references should not just be for Python wizards. Whether you have a cache, memoizing a function, tracking objects, or various other bookkeeping needs, you definitely do not want code leaking memory or resources. In this talk, we will look at illuminating examples drawn from a variety of sources on how to use weak references to prevent such bugs.
