Because the whole Storm is to be started and the source code level. so I started learning Clojure. I have heard of functional programming before, and I have heard that Erlang is awesome. I only know it when I contact Clojure. It turns out that Clojure is Erlang in JVM. there are too few materials for Clojure developmen

But a "declining aristocrat" has been reproduced in front of you, it is a functional programming language.Functional programming language once disappeared in the lake, perhaps most people only in the ivory tower to appreciate their demeanor. Its "decline" is not without reason, such as early people on its performance of the question and so on. However, with the wind of the big data age, the heir

In a keynote speech with Martin Fowler, he provided an astute observation:
Java's legacy is platform, not language.
The original Java Technology engineer made a terrific decision to detach the language from the runtime, eventually enabling more than 200 languages to run on the Java platform. The infrastructure is critical to the long-term viability of the platform, because the computer programming language is usually short-lived. The JVM language summit, hosted by Oracle every year since 2008,
