If you have two days to learn the very basics of modelling, Domain-Driven Design, CQRS and Event Sourcing, here's what you should do:

In the evenings read the [Domain-Driven Design Quickly Minibook]{http://www.infoq.com/minibooks/domain-driven-design-quickly}. During the day watch following great videos (in this order):

1. Eric Evans' [What I've learned about DDD since the book]{http://www.infoq.com/presentations/ddd-eric-evans}
2. Eric Evans' [Strategic Design - Responsibility Traps]{http://www.infoq.com/presentations/design-strategic-eric-evans}

Post Strange Loop BBQ Tour

Like [last year][1] I am planning to visit many of the BBQ joints in Saint Louis, most of which are not in walking distance of the conference venues. Unlike in 2015, the [Q in the Lou BBQ][6] festival will not conveniently overlap dates with the Strange Loop conference- Q in the Lou will occur the weekend following Strange Loop.

Itinerary

This is the itinerary. We will leave Union Station in groups using UberXLs or cabs around 10:30 am. Meet outside the main doors at Union Station Double Tree on Market Street.

(= "bar" ({:foo "bar"} :foo))     ; map as function
(= "bar" (:foo {:foo "bar"}))     ; key as function
(= "bar" (get {:foo "bar"} :foo)) ; `get` as function
