So... what's it doing? More explanation would be nice.

i guess it displays gowalla checkins on a map in real time using "fancy" web technologies :)

Petty much!

Looks like it's just a visual log of one persons' check-ins.

It's moving way too fast to be entertaining or interactive. If you slowed it down, people could zoom in for a much closer look and it would actually be a cool slideshow style display.

Hey, that's not really the purpose, but to show how simple it it to connect PubSubHubbub to Webhooks :)

julien4• 16 years ago

For those who ask what it is : PubSubHubbub and Webhooks (HTML5) integrated.

Gowalla publishes its feeds thru PubSubHubbub. I built a small node.js server that can subscribe to these feeds. Then, this exact same server is a WebSocket server. The browser open a websocket connection to the server, which then subscribes to the hub. When the server gets updates it pushes them to the browser.

Yeah, I'm not sure 3.6.8 implements WebSockets.

Doesn't seem to work in Firefox 4.0 (b3), which should have WebSockets...

(I think it might be a different protocol version from what Chrome supports, which is exactly the reason it sucks when browsers go out there with protocols that aren't more mature yet).

I thought websockets have to make a connection to your server from the same domain? How are you getting around this?
