i wrote this because, while i think the things on this list are potentially worth knowing, and I actually think it's an awesome list of project ideas as well as good food for thought for people developing CS curricula (many of the things I don't know are great exercises!) -- I thought it was really weird to say that every CS student should know all of them.

DDD/CQRS/ES/Architecture videos

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:

  2. Eric Evans' [Strategic Design - Responsibility Traps]{http://www.infoq.com/presentations/design-strategic-eric-evans}
  3. Udi Dahan's [Avoid a Failed SOA: Business & Autonomous Components to the Rescue]{http://www.infoq.com/presentations/SOA-Business-Autonomous-Components}
  4. Udi Dahan's [Command-Query Responsibility Segregation]{http://www.infoq.com/presentations/Command-Query-Responsibility-Segregation}
