  • 这本书还没正式出版,但看起来相当硬核,可能挺有用:http://www.amazon.com/Erlang-Run-Time-System-Erik-Stenman/dp...

    This book hasn't been released yet, but it seems quite interesting and might be useful: http://www.amazon.com/Erlang-Run-Time-System-Erik-Stenman/dp...

  • ……概念。Erlang 虚拟机具有一种可称为“绿色进程”(green processes)的机制——它们类似于操作系统进程(不像线程那样共享状态),但是是在 Erlang 运行时系统(ERTS, Erlang Run Time System)内部实现的。这些有时被称为“绿色线程”(green threads),但与标准的绿色线程有着显著区别。

    …concept. The Erlang virtual machine has what might be called "green processes" – they are like operating system processes (they do not share state like threads do) but are implemented within the Erlang Run Time System (erts). These are sometimes referred to as "green threads", but have significant differences from standard green threads.

  • BEAM 虚拟机和 Erlang 运行时系统(ERTS)的语义,要比 Python 的语义更接近典型的大型动态 Web 应用后端。这并不奇怪,它最初就是为了支持电话交换机而设计的。它原生提供了……功能

    The semantics of the BEAM VM and Erlang Run-Time System (ERTS) are much closer to the typical semantics of a large dynamic web app backend than those of Python. No surprise there, it was designed to support telephone exchanges. It provides facilities natively…

  • 如果我没记错的话,Erlang 运行时系统(BEAM VM)本身基本上就是一个操作系统,主要由 Erlang 的一个子集和 C/C++ 编写而成。

    If I'm not mistaken, the Erlang Run Time System (BEAMVM) is basically an operating system, in itself, written mostly in a subset of Erlang and C/C++.

  • ……只见树木不见森林,很可能会给 Erlang 新手留下错误的印象。大家常说的 Erlang 永远是 Erlang/OTP(即语言本身加上库提供的组件设计模式)+ Erlang 运行时系统(ERTS,即 BEAM 虚拟机及辅助组件)。正是整个“系统”让它在一个单一环境下变得如此强大和高度统一。每一个单独的“特性”都只存在于整体的上下文中,不能单独……

    …missing the forest for the trees and probably giving a wrong impression of Erlang for people new to it. Erlang is always spelled as Erlang/OTP (i.e. language/patterns of components provided in libraries) + Erlang Run Time System(ERTS) (the BEAM VM + support components). The whole "System" is what makes it so powerful and uniform with a single environment. Every single "feature" exists only in the context of the whole and cannot…
