Erlang & la resilienza con pattern matching e processi

Cosa ci insegna Erlang sulla resilienza, in un periodo in cui ce ne è molto bisogno? Erlang è un linguaggio open source nato nel 1986 alla Ericsson, di tipo funzionale, concorrente, dinamicamente tipato, general purpose e soprattutto costruito per essere “resiliente” sia dai primi giorni della sua nascita. E’ il motore dietro RabbitMQ e CouchDB, …

From the site: A property-based testing tool, when supplied with this information, should randomly produce progressively more complex valid inputs, …

Erlang è un linguaggio a mio avviso sottostimato, che ha parecchie cose da insegnare ai vari Scala/Rust/Java(Script) out of there… In particolare ci sono un insieme di feature di Erlang che prese singolarmente non sono difficili da comprendere e implementare, ma è l’insieme delle idee fondanti di Erlang che lo rende assai diverso dagli altri. …

This article is a work in progress: it will be expanded by your comments… Python is a very curios programming languages: it give you classes but also a strong function-oriented environment to play with.
