NetKernel

NetKernel's resource-oriented computing model makes it simple to construct powerful software. NetKernel's advanced infrastructure extends the core ideas behind Unix and REST. From Unix - compose functions and whole applications using a toolbox of services that work directly with resources. From REST - address everything with a logical URI address (resources, services and code) and find the immutable results cached, eliminating redundant computations. The result is a platform that supports rapid development of incredibly fast flexible applications.

NetKernel Stack

NetKernel是一个软件系统，它将REST和Unix的基本属性组装成一个叫做面向资源计算（resource oriented computing，ROC）的强大的抽象集。面向资源计算的核心是将信息（资源）的逻辑请求与传递请求的物理机制（代码）相分离。与其他方式相比，使用ROC构建的应用已被证明是小巧的、简单的、灵活的，并且无需太多代码。

Scripting

[[Image:netkernel-script-data.png|right|thumb|JavaScript program processes] Language runtimes are activated by calling the runtime as an active: service. NetKernel 3.3 supports:

active:beanshell

active:beanshell+operator@ffcpl:/myprogram.bsh

active:javascript

active:javascript+operator@ffcpl:/program.js+data@ffcpl:/data.xml

active:groovy
active:python
active:ruby

The following versions of script language runtimes are used in NetKernel 3.3.

BeanShell v1.3.0
JRuby 1.0.1
Rhino Javascript v1.6 R2 - with patches to E4X
Groovy v1.0 JSR 05
Jython v2.2
