Token Authentication vs. Cookies
...er. This way the server can maintain a session with the stateless client, knowing mostly everything about the app's state, but stored in the server. In this scenario at no moment does the client hold state, which is not how Ember.js works.

Chaining multiple filter() in Django, is this a bug?
...__event=event) & Q(shiftregistrations__shifts=False)
What you can do now is to use an annotation count-filter.

How line ending conversions work with git core.autocrlf between different operating systems

In fact, all these translations (any EOL conversion from eol= or autocrlf settings, and "clean" filters) are run when files move from work-tree to index, i.e., during git add rather than at git commit time. (Note that gi...
