This article is not just very well written, it's also very funny.

I love when you can mix technicals and not taking yourself seriously. Although be careful with using DB as a task queue. Concurrency is a b* and message brokers are very good at it. AMPQ has been created because the authors started with a BD message broker and it didn't work. A task queue is message broker + persistance + status. Celery does that very well in the Python word, and works with rabbitmq, redis, postgres, etc. What amaze me the most is autobahn + crossbar.io. It does PUB/SUB, RPC, load balancing and all the stuff for Python, JS, PHP, C#, Java... And it works even in the browser. Cool stuff.
