Nice article!

I am not that familiar with py-amqplib but the no_ack argument to 
basic_consume/basic_get is defined in the AMQP spec to mean that the 
server should not expect an ack and should discard the message on 
delivery. I.e. its an unreliable mode of delivery[1] rather than a 
signal to the client library to automatically acknowledge on receiving a 

One simplification that I think is sometimes nice to mention is using 
the 'default exchange' to emulate publishing directly to a queue. E.g.


It avoids the need to explicitly bind a queue in situations where 
fancier routing is not required.

[1] This makes sense for example if you have a private queue bound to an 
exchange as a 'subscription' to published events. If your client fails 
the queue will disappear, so acking is not adding anything.
