<p><strong><a href="http://github.com/blog/542-introducing-resque">Introducing Resque</a></strong></p> A new background worker management queue developed at GitHub, using Redis for the persistence layer. The blog post explains both the design and the shortcomings of previous solutions at length. Within 24 hours of the release code an external developer, Adam Cooke, has completely reskinned the UI. <p>Tags: <a href="https://simonwillison.net/tags/github">github</a>, <a href="https://simonwillison.net/tags/open-source">open-source</a>, <a href="https://simonwillison.net/tags/queue">queue</a>, <a href="https://simonwillison.net/tags/redis">redis</a>, <a href="https://simonwillison.net/tags/resque">resque</a>, <a href="https://simonwillison.net/tags/ruby">ruby</a>, <a href="https://simonwillison.net/tags/sinatra">sinatra</a>, <a href="https://simonwillison.net/tags/workers">workers</a></p>

<p><strong><a href="http://github.com/documentcloud/cloud-crowd">cloud-crowd</a></strong></p> New parallel processing worker/job queue system with a strikingly elegant architecture. The central server is an HTTP server that manages job requests, which are farmed out to a number of node HTTP servers which fork off worker processes to do the work. All communication is webhook-style JSON, and the servers are implemented in Sinatra and Thin using a tiny amount of code. The web-based monitoring interface is simply beautiful, using canvas to display graphs showing the system’s overall activity. <p>Tags: <a href="https://simonwillison.net/tags/canvas">canvas</a>, <a href="https://simonwillison.net/tags/cloudcrowd">cloudcrowd</a>, <a href="https://simonwillison.net/tags/http">http</a>, <a href="https://simonwillison.net/tags/json">json</a>, <a href="https://simonwillison.net/tags/message-queues">message-queues</a>, <a href="https://simonwillison.net/tags/ruby">ruby</a>, <a href="https://simonwillison.net/tags/sinatra">sinatra</a>, <a href="https://simonwillison.net/tags/thin">thin</a>, <a href="https://simonwillison.net/tags/webhooks">webhooks</a>, <a href="https://simonwillison.net/tags/workers">workers</a></p>
