    Don Julián!
Me quedé sorprendido por las respuestas que le dieron a su pregunta de cómo enseñarle a nuevos devs a modelar un sistema.
Me horrorizó ver respuestas que hablaban que DDDesign es demasiado, o que FP y DDDesign no van; o peor aún, que sospechan que ágil y DDDesign no pueden ir juntas.
Hace unos años escribí sobre el concepto de la simpatía semántica, un copy/paste de la Simpatía Mecánica de Thompson. Considero que ese debería ser ppal mensaje que me hubiera gustado que me enseñaran cuando arranqué a trabajar "profesionalmente".
Si ese concepto es claro, no debería importar si ud usa UML o no, si usa cajitas y rayitas para definir mapas semánticos o lo que quiera. Parafraseando a Fowler, lo importante de UML es comunicar. En este caso, comunicar la abstracción del mundo real que luego convertirá en código fuente.

    Hola!
Hace más de dos años venimos trabajando en diferentes tipos de proyectos haciendo uso de Akka/JVM/Scala. A la fecha hemos entregado exitosamente 14 proyectos de tamaño medio a grande, pasando por webapps, automatizaciones de procesos de laga duración, sistemas de autenticación y autorización, service registries, aplicaciones core de negocio, entre otros ejemplos.
En la mayoría de ellos hemos tenido que resolver problemas a través de la construcción de patrones para sistemas distribuidos: convergencia de estado a través de CvRDT, quórum a través de RAFT (hecho en casa), jitter y exponential backoff en el consumo de servicios, implementación de sagas para soportar transacciones de larga duración o no tan simples esquemas de recuperación ante catástrofes sobre distintos IaaS.
Lo que quiero tratar de decir con esta introducción es que calcular pi, o cualquier otro problema algorítmico es lo menos común de los problemas en los que hemos elegido Akka para resolverlos. De hecho, en las pruebas que hicimos d
