What is the history of Django? I’ve been playing with Quora—it’s a really neat twist on the question-and-answer format, which makes great use of friends, followers and topics and has some very neat live update stuff going on (using Comet on top of Tornado). I just posted quite a long answer to a question about the history of Django. # 24th August 2010, 5:31 pm
Hookbox (via) For most web projects, I believe implementing any real-time comet features on a separate stack from the rest of the application makes sense—keep using Rails, Django or PHP for the bulk of the application logic, and offload any WebSocket or Comet requests to a separate stack built on top of something like Node.js, Twisted, EventMachine or Jetty. Hookbox is the best example of that philosophy I’ve yet seen—it’s a Comet server that makes WebHook requests back to your regular application stack to check if a user has permission to publish or subscribe to a given channel. “The key insight is that all application development with hookbox happens either in JavaScript or in the native language of the web application itself”. # 29th July 2010, 9:48 am
nginx_http_push_module. More clever design with webhooks—here’s an nginx module that provides a comet endpoint URL which will hang until a back end process POSTs to another URL on the same server. This makes it much easier to build asynchronous comet apps using regular synchronous web frameworks such as Django, PHP and Rails. # 17th October 2009, 4:48 pm
Tornado Web Server (via) An extremely exciting addition to the Python web landscape, Tornado is the open sourced version of FriendFeed’s custom web stack. It’s a non-blocking (epoll) Python web server designed for handling thousands of simultaneous connections, perfect for building Comet applications. The web framework is cosmetically similar to web.py or App Engine’s webapp but has decorators for writing asynchronous request handlers. The template language uses Django-style syntax but allows you to use full Python expressions. FriendFeed have benchmarked it handling 8,000 requests a second running as four load-balanced processes on a 4 core server. # 10th September 2009, 9:32 pm
Spawning + Django. The latest version of Spawning (a fast Python web server built on top of the Eventlet non-blocking coroutine networking library) can run Django applications out of the box, using threads and processes to work around the blocking nature of the ORM’s database drivers. Eric Florenzano reports better performance than Apache and mod_wsgi, and is now hosting his site on it. # 31st July 2008, 10:56 am
On-board vs. Off-board Comet. Useful distinction. On-board comet runs on the same server as the rest of your application; Off-board comet is served from a separate server (generally a subdomain) and a separate stack. If you want to stick with PHP, Rails or Django for the rest of your site off-board comet looks like the way to go. # 22nd May 2008, 5:02 pm
django-evserver. Marek Majkowski got Comet working with Django using a custom WSGI server that wraps libevent using ctypes. # 19th January 2008, 12:15 pm
Django and Comet. How to build a chat application using Django and the Orbited comet server. Orbited can be set up to proxy most requests through to a Django backend while handling any comet requests itself. # 26th December 2007, 9:05 pm
