TL;DR: Links I tweeted during 2015

It's funny how old principles are still useful today. In 2015, the most important ones I've learned are the following:

• Command/Query Responsibility Segregation (CQRS): separate the "read" logic from the "write" logic
• Event Sourcing (ES): recording every action done for analytics and rollback purpose
• Command Bus: store and validate input in a Command object, pass it to a Command Bus middleware that will find and execute the appropriate Command Handler which will execture the logic
• Framework / Library agnosticism: decouple from vendors to be able to change/upgrade them without friction
• microservices: reduce the scope of an API, organize them into a communicating network
• Monolithic Repository: store related applications in the same git repository

It was a year full of links, so here they are!
