I want to build a live application that supports server-push (chat, feeds, live notification and collaboration etc). I have looked into Node.js and found it quite interesting and appropriate for such things. I have also looked into AMQP/RabbitMQ, but I don't get these quite. My questions: How does AMQP/RabbitMQ compare to Node.js? C...
I saw that they soon will have an addon for AMQP. I'm about to learn how to use AMQP with RabbitMQ. I suppose that that addon doesn't deal with RabbitMQ. Isn't AMQP just a protocol. Are they using any AMQP broker like RabbitMQ or ActiveMQ? ...

Hi, I have worked with TIBCO RV on applications that require low latency messaging. I have heard of projects where the team had to roll out their own socket code to get messages faster than the speed offered by RV. Are there any tools out there, probably open source that can come close to or better than TIBCO RV? Thanks Hari ...

Can anyone give me a clear and easily understandable explanation of what MOM is, and possibly some simple examples of how it's used outside of enterprise? ...

Hi, I have a pylons based webapp and i'd love to use celery + rabbitmq for some time taking tasks. I've taken a look at the celery-pylons project but I haven't succeeded in using it.

I have a question that I cant seem to find an answer on. This is my first time using RabbitMQ in a "big" application and am wondering how the queues work in a cluster. I understand that the routing information (queues, exchanges, bindings) is on all nodes in the cluster, but the queue its self resides on the machine that it was created o...
