After yesterday’s screencast showing the use of coffeeshop from the command line, here’s one that expands upon the direction I’m taking the implementation, following the REST/HTTP philosophy. It shows, I hope, that embracing REST-orientated HTTP features, such as content negotiation (”conneg”), and the concepts of resources and representations, gives you a fantastically flexible and straightforward [...]
To follow on from the first coffeeshop demo screencast, I thought I’d make another. This time it’s to highlight the fact that coffeeshop is fundamentally a REST-orientated, HTTP-based pubsub application at the core, and not just a web-based application. Hopefully this comes across through the use of command-line HTTP tools to manipulate Channel, Subscriber and [...]
There’s an interesting article “HTTP PubSub: Webhooks and PubSubHubBub” that covers working with webhooks and points to a great HTTP / webhook developer utility “PostBin“, which:
“lets you debug web lets you debug web hooks by capturing and logging the asynchronous requests made when events happen. Make a PostBin and register the URL with a web [...]
To demonstrate some of the basic coffeeshop features, I put together a screencast, and after getting over the shock of hearing my own voice in the recorded voiceover (last time I chickened out and just typed what I wanted to say), I put it up on YouTube:

The screencast shows the creation of a channel, the [...]
‘Coffeeshop‘ is a lightweight, REST-orientated HTTP-based publish/subscribe implementation that I’ve been working on for the last few days. It is a culmination of:
an early and long-standing interest in pubsub
a fascination with using HTTP properly, i.e. as an application protocol, not a transport protocol
an excuse to experiment in the area of webhooks
a desire to learn more [...]
