• Fighting Bottlenecks with CQRS - I hadn’t done any presentations or blog posts about Command/Query Responsibility Segregation yet, even though I’ve been working with it for more than year (and have been wanting to use it for another year). Volker Dusch invited me to speak at the first ResearchGate Developer Day in Berlin, and offered me the luxury to choose any SE topic I wanted, I just had to do it. See the slides on Speakerdeck Volker gave me a tour of the ResearchGate office. They’re all about sharing scientific research. It’s a fast growing startup, with an awesome culture, and they’re hiring, so check them out. [Mathias Verraes]

• Value Objects and User Interfaces - I got this mail from a listener of the podcast episode on Value Objects I recorded with Konstantin: I've been listening to your Elephant in the room podcast Episode #002, i was wondering if you have a coding example of where you use the Country as a value object and not as an entity. I've come across this problem too, and was hoping you may have an example that i can look at to give me a better understanding in terms of how to code this? My first question would really be how would you logically store a list of all countries outside of a database if you were using value objects for use in a Form lookup field? There’s nothing intrinsically wrong with modelling countries as entities and storing them in the database. But in most cases, that overcomplicating things. Countries don’t change often. When a country’s name changes, it is in fact, for all practical purposes, a new country. If a country one day does not exist anymore, you can’t simply change all addresses, because possibly the country was split into two countries. [Mathias Verraes]
