HTTP PubSub: Webhooks & PubSubHubbub - igvita.com
The best part about Webhooks is that most of us are already familiar with them: callbacks over HTTP. Pioneered by PayPal and Subversion as a way to send real-time notifications to the client, they have found their way into many dozens of products we all use every day. Need pre or post commit hooks for your SVN or Git repository? Both GitHub and SVN support HTTP callbacks. Need a payment alert from PayPal, or an alert when a wiki page is modified? There are webhooks for that too. This simple mechanism allows us to build web services that work together via a simple and ubiquitous protocol we can all understand: HTTP!
"We offer this spec in hopes that it fills a need or at least advances the state of the discussion in the pubsub space. Polling sucks. We think a decentralized pubsub layer is a fundamental, missing layer in the Internet architecture today and its existence, more than just enabling the obvious lower latency feed readers, would enable many cool applications, most of which we can't even imagine. But we're looking forward to decentralized social networking."
With all the recent buzz about real-time web, surely this is the year XMPP/AMQP Publish-Subscribe (PubSub) makes it to the big leagues! Or maybe not. Ejabberd (XMPP), RabbitMQ (AMQP) and other pubsub server implementations have come a long way but they remain cumbersome to setup and maintain,The Pushbutton Web: Realtime Becomes Real - Anil Dash
Pushbutton is a name for what I believe will be an upgrade for the web, where any site or application can deliver realtime messages to a web-scale audience, using free and open technologies at low cost and without relying on any single company like Twitter or Facebook. The pieces of this platform have just come together to enable a whole set of new features and applications that would have been nearly impossible for an average web developer to build in the past.

Anil Dash of Six Apart weaves together several ideas, some very old, some relatively new, and spins a story of the web to come. This is a great read, rich with informative links. Web developers should read it twice and argue about for hours.ウノウラボ Unoh Labs: PubSubHubbubとは

Both PuSH and rssCloud address a fundamental flaw in the way web applications work today. Currently, getting updates on the web requires constant polling. Subscribers are forced to act like nagging children asking, “Are we there yet?” Subscribers must constantly ping the publisher to ask if there are new updates even if the answer is “no” 99% of the time. This is terribly inefficient, wastes resources, and makes it incredibly hard to find new content in as soon as it appears. Both protocols flip the current model on its head so that updates are event driven rather than request driven. By that I mean that both protocols eliminate the need for polling by essentially telling subscribers, “Don’t ask us if there’s anything new. We’ll tell you.”Real-Time Web Protocol PubSubHubbub Explained

「PubSubHubbub」（パブサブハブバブ）という奇妙な名前のプロトコルが注目だ。2009年8月5日にグーグルはRSSリーダーサービスのGoogle ReaderでPubSubHubbub対応を明らかにしたほか、国内ではライブドアが、同じくRSSリーダー「livedoor Reader」とブログサービスの「livedoor Blog」でPubSubHubbubに初対応したことを8月18日に発表している。まだ対応サービスは少なく、その“効能”も「ブログの更新がRSSリーダーに反映されるのが、ほぼリアルタイムになりました」というだけで小さく見えるかもしれない。しかしPubSubHubbubは、ネット全体のリアルタイムコミュニケーションプラットフォーム化を促す重要なキーとなるかもしれない。
