Django is being used by corporations worldwide.  Every day, Imaginary does its part to increase this footprint by deploying Django websites and applications to our clients. As a result, Django is being exposed to greater numbers of end users. I'm not talking end user developers.  I'm talking Samantha in marketing...

At Imaginary Landscape, we often have the need to add remote file storage capabilities for our clients. At first glance, this sounds easy enough: "pip install django-storages", add the right credentials, and boom, you're done! However, this was not the case for one particular situation we encountered.

A 2014 study released by the Harvard Law Review shows that an alarming number of hyperlinks go bad in a surprisingly short time. Link Rot has been a problem from the very beginning of the web.  Over time, websites can come-and-go and redesigns can change the location of content -...
