Django CSRF check failing with an Ajax POST request
... lovely way of doing it from a technical point of view, but it does look a bit verbose.
In the past, I have done it more simply by getting the javascript to put the token value into the post data.
If you use {% csrf_token %} in your template, you will get a hidden form field emitted that carries t...
Which websocket library to use with Node.js? [closed]
...es mentioned are released since then.
Socket.IO v0.9 is outdated and a bit buggy, and Engine.IO is the
interim successor. Socket.IO v1.0 (which will be released soon) will

NoSQL (MongoDB) vs Lucene (or Solr) as your database
...
This is a great question, something I have pondered over quite a bit. I will summarize my lessons learned:
You can easily use Lucene/Solr in lieu of MongoDB for pretty much all situations, but not vice versa. Grant Ingersoll's post sums it up here.

Add this to your Git configuration by running git config -e --global

cleanup = "!git branch --merged | grep -v '\\*\\|master\\|develop' | xargs -n 1 git branch -d"
And then you can delete all the local m...
