During the writing of a recent post about connascence for Codesai's blog some of us were discussing whether we could consider a data clump a form of Connascence of Meaning (CoM) or not. In the end, we agreed that data clumps are indeed a form of CoM and that introducing a class for the missing abstraction reduces their connascence to Connascence of Type (CoT). I had wondered in the past why we use a similar refactoring to eliminate both primitive obsession and data clump smells. Thinking about t...

This post appeared originally on Codesai’s Blog. As we saw in our previous post about connascence, Connascence of Position (CoP) happens when multiple components must be adjacent or appear in a particular order. CoP is the strongest form of static connascence, as shown in the following figure. Connascence forms sorted by descending strength (from Kevin Rutherford's XP Surgery). A typical example of CoP appears when we use positional parameters in a method signature because any cha...

"Una de los conceptos que DDD nos ofrece para desacoplar nuestro código son los eventos de dominio. En letgo hay picos diarios de +10.000.000 eventos por hora (3.000/s). Esto supone un reto y cualquier optimización tiene un impacto notable. La charla consta de cómo estaban hecho los consumers antes (spoiler: alguna que otra vez se llegó a levantar 100 máquinas) y cómo lo están ahora. La charla es agnóstica del lenguaje de programación, aunque se explicarán truquillos de cómo hacerlos en php, y sobre todo, de cómo molar mucho utilizando Akka desde Scala o Java."
