Last night I woke up at 2am and realized that there was a fundamental problem with cursor preservation in today’s real-time collaborative applications [...] MobWrite now has what I believe to be the most advanced cursor preservation algorithm available.

The Pushbutton Web: Realtime Becomes Real. Anil Dash is excited by the potential for PubSubHubBub and Webhooks to make near-real-time scalable event publishing accessible to regular web developers. So am I. # 24th July 2009, 6:30 pm

EtherPad. Outstanding implementation of an online real-time collaborative text editor—basically SubEthaEdit in your browser. I can see myself using this a lot. # 24th July 2009, 12:35 am

pubsubhubbub. From Brad Fitzpatrick, a simple but clever way of using web hooks (HTTP callbacks) to inform subscribers that an Atom feed has updated in almost real-time—solving the constant polling problem and making it easier for small sites to offer publish-subscribe APIs. Any Atom feed can delegate subscriber updates to a “hub” server. An example hub server implementation is provided running on App Engine. # 20th April 2009, 6:49 pm

Giant, Python Powered Robots. “They each weigh about 11 tonnes and have a 17 meter reach. The control system is written in Python, with small sections of C which run in hard-real-time to guarantee safety.” # 28th January 2009, 10:35 am

Simple Update Protocol: Update. Already implemented by more than five services, each of which now have near-real-time updates in to the FriendFeed syndication engine. # 18th December 2008, 11:33 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
