• Snapshots in Event Sourcing - One of the great benefits of Event Sourcing is that you don't lose any business data. Each business operation ends with a new event appended to the event store. The business object is represented by the sequence of events called a stream. When we want to execute business logic, we're reading all events from a specific stream. We're recreating the current state by applying all the events one by one in order of appearance. Based on the current state, we verify and execute the business logic. [Event Store blog]

• The “It's Just Like...” Heuristic - There’s a common bias in the tech industry, and I imagine everywhere. When there’s a new idea, and some very smart people will say that the new idea X is really just the old idea Y. The idea could be a model for looking at things, a way of doing things, a technology, a pattern. People will make the case that X is nothing but Y in new packaging. Brain Rewards Sometimes it really is just new packaging. But: Your brain rewards you for classifying new information into existing buckets1. [Mathias Verraes]
