ptth (Reverse HTTP) implementation in a browser using Long Poll COMET. Donovan Preston experiments with the cleverly named idea of ptth, where servers send HTTP requests to clients. # 8th December 2008, 5:22 pm
FriendFeed launch a real-time API. This is huge: JSONP plus long polling Comet, with “everything since X” tokens to ensure you don’t miss anything. This is the first open Comet API I’ve seen anywhere. Combine this with FriendFeed’s regular API (which allows arbitrary message posting) and you’ve got a really powerful tool for hackers who want to experiment with Comet without rigging up their own infrastructure. # 22nd October 2008, 2:18 pm
A Million-user Comet Application with Mochiweb, Part 1. Richard Jones explores Mochiweb, Erlang and linux kernel tuning for building a high performance comet server. Does this mean real-time web features are coming to last.fm? # 16th October 2008, 2:16 pm
Private Messages with cometD Chat. cometd-java (a Java servlet reference implementation of the Bayeux protocol) can be extended with BayeuxService subclasses that run within the server itself. # 16th October 2008, 2:14 pm
View your FriendFeed in real-time. FriendFeed become the latest site to enable real-time updates using the long-polling variant of Comet. The real-time Web was something of a theme at this year’s FOWA, with talks on message queues, XMPP and scaling Comet at Meebo. # 16th October 2008, 2:06 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
How Comet Brings Instant Messaging to meebo. “What started off as a hack appears to be fulfilling one of the most basic needs of the Web, which is live synchronous interaction”—Jian Shen # 27th July 2008, 11:18 am
Independence Day: HTML5 WebSocket Liberates Comet From Hacks. The HTML5 spec now includes WebSocket, a TCP-style persistent socket mechanism between client and server using an HTTP handshake to work around firewalls. The Orbited comet implementation provides a WebSocket compatible API to existing browsers today, and can also act as a firewall/proxy between WebSocket and regular TCP sockets, allowing browsers to talk to things like XMPP servers using Orbited to bridge the gap. # 4th July 2008, 9:54 am
Enough Already with the Connections! Comet doesn’t mean making long-lived HTTP connections (which most browsers do anyway thanks to HTTP keep-alive), it means making long-held HTTP requests. I’m guilty of spreading this misinformation in the past. # 30th June 2008, 9:27 am
Comet (programming) on Wikipedia on 4th June 2008 (via) The last useful version (which I had pointed many people to) before it was gutted down to just a couple of paragraphs by infuriating deletionists. # 16th June 2008, 9:34 am
Saturday Mornings: Going Live! Some 1980s/1990s British nostalgia. I pinched a video of the theme tune from here for my talk on Comet at Brighton SkillSwap. # 12th June 2008, 12:14 am
Google Finance Comet. Google Finance now shows live stock quotes, updated by Comet. # 4th June 2008, 8:36 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
Engineering @ Facebook: Facebook Chat. The new Facebook Chat uses Comet (long polling with a hidden iframe) against a custom web / chat server written in Erlang, designed to handle a launch to all 70 million users at once. It was tested using a “dark launch” period where live pages simulated chat request traffic without showing any visible UI. # 15th May 2008, 7:55 am
Persevere adds Comet Support. Persevere sounds neat: a RESTful HTTP/JSON data store (the interface reminds me of CouchDB) which recently gained the ability to “subscribe” to a resource and receive notifications of updates via comet. # 13th May 2008, 8:09 am
Comet at the Highland Fling. I thoroughly enjoyed the Highland Fling yesterday. Here are the slides from my talk on Comet. # 4th April 2008, 10:13 am
A Toy Chat Server with Eventlet and Mulib (via) Eventlet (the Python non-blocking IO library originally written for Second Life) is ideally suited to building Comet servers; Chuck Thier demonstrates a simple chat server in a small amount of code. # 21st March 2008, 3:28 am
Internet Explorer 8 Readiness Toolkit. The new built-in development tools look similar enough to Firebug to make me very happy. Also of interest: Selectors API (for fast getElementsBySelector), CSS 2.1 support, support for XHTML style namespaces in HTML, an interesting Web Slices feature based on the hAtom microformat and 6 connections per host (up from 2) which should make Comet easier. # 5th March 2008, 6:28 pm
Gears 0.2 Released! New modules are HttpRequest and Timer, both for use within workers (which provide Erlang-style message passing concurrency). Particularly interesting is that the Gears HttpRequest module can be used for much cleaner Comet implementations in IE. # 5th March 2008, 12:21 am
Let me be again clear here that Comet isn’t a new single technique. Rather, it’s a combination of existing push technologies with further research into new methods that together provides a robust framework for pushing data to all clients on modern networks.

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
$.comet (via) The first Comet (with Bayeux) plugin I’ve seen for jQuery—currently only handles long-polling over XMLHttpRequest, but still a promising start. # 9th January 2008, 8:31 am
Why we switched to Jetty. Zimbra (recently acquired by Yahoo!) are using Jetty for Comet. It sounds like they are using Bayeux as well. # 8th January 2008, 5:12 am
20,000 Reasons Why Comet Scales. Greg Wilkins coaxes Jetty and Bayeux in to supporting 20,000 simultaneous users per server while maintaining sub-second latency, using Amazon EC2 to run the benchmark. # 7th January 2008, 8:32 am
