来自西雅图的消息。当前 IT 界最热的词汇是“容器”，美国有两大研讨会：Linuxcon USA 和 Containercon，后者就是为容器而生的。
|
||||
|

Docker 公司是开源 Docker 项目的商业赞助商，本次研讨会这家公司有 3 位高管带来主题演讲，但公司创始人 Solomon Hykes 没上场演讲。
|

|

Hykes 曾在 2014 年的 Linuxcon 上进行过一次主题演讲，但今年的 Containeron 他只坐在观众席上。而工程部高级副总裁 Marianna Tessel、Docker 首席安全员 Diogo Monica 和核心维护员 Michael Crosby 为我们演讲 Docker 新增的功能和将来会有的功能。

Ubuntu 开源操作系统运行在中国 42% 的 Dell PC 上
|
||||
================================================================================
|
||||
|
||||
> Dell 称它在中国市场出售的 42% 的 PC 运行的是 Kylin，这是一款 Canonical 帮助开发的基于 Ubuntu 的操作系统。
|
||||
|
||||
让开源粉丝欢喜的是：Linux 桌面年来了。或者说中国正在接近这个目标，[Dell][1] 报告称它售卖的超过 40% 的 PC 机运行的是 [Canonical][3] 帮助开发的 [Ubuntu Linux][2]。
|
||||
|
||||
特别地，Dell 称 42% 的中国电脑运行 NeoKylin（中标麒麟），一款中国本土倾力打造的用于替代 [Microsoft][4] Windows的操作系统。它也简称麒麟，这是一款从 2013 年出来的基于 Ubuntu 的操作系统，也是这年开始 Canonical 公司与中国政府合作建立一个专供中国市场的 Ubuntu 变种。
|
||||
|
||||
麒麟的早期版本出现于 2001 年左右，也是基于其他操作系统，包括 FreeBSD，这是一个开放源码但是不同于 Linux 的类 Unix 操作系统。
|
||||
|
||||
Ubuntu 麒麟的外观和感觉很像 Ubuntu 的现代版本。它拥有的 [Unity][5] 界面，并运行开源软件的标准套件，以及专门的如 Youker 助理程序，它是一个图形化的前端，帮助用户管理基本计算任务。但是麒麟的默认主题使得它看起来有点像 Windows 而不是 Ubuntu。
|
||||
|
||||
鉴于桌面 Linux PC 市场在世界上大多数国家的相对停滞，戴尔的宣布是令人吃惊的。结合中国对当前版本 windows 的轻微[敌意][6]，这个消息并不看好着微软在中国市场的前景。
|
||||
|
||||
紧跟着 Dell 公司[宣布][7]在华投资1.25亿美元之后，一位决策者给华尔街杂志的评论中提到了 Dell 在中国市场上 PC 的销售。

How to Setup Node JS v4.0.0 on Ubuntu 14.04 / 15.04
|
||||
================================================================================
|
||||
Hi everyone, Node.JS Version 4.0.0 has been out, the popular server-side JavaScript platform has combines the Node.js and io.js code bases. This release represents the combined efforts encapsulated in both the Node.js project and the io.js project that are now combined in a single codebase. The most important change is this Node.js is ships with version 4.5 of Google's V8 JavaScript engine, which is the same version that ships with the current Chrome browser. So, being able to more closely track V8’s releases means Node.js runs JavaScript faster, more securely, and with the ability to use many desirable ES6 language features.
|
||||
|
||||
|
||||
|
||||
Node.js 4.0.0 aims to provide an easy update path for current users of io.js and node as there are no major API changes. Let’s see how you can easily get it installed and setup on Ubuntu server by following this simple article.
|
||||
|
||||
### Basic System Setup ###
|
||||
|
||||
Node works perfectly on Linux, Macintosh, and Solaris operating systems and among the Linux operating systems it has the best results using Ubuntu OS. That's why we are to setup it Ubuntu 15.04 while the same steps can be followed using Ubuntu 14.04.
|
||||
|
||||
**1) System Resources**
|
||||
|
||||
The basic system resources for Node depend upon the size of your infrastructure requirements. So, here in this tutorial we will setup Node with 1 GB RAM, 1 GHz Processor and 10 GB of available disk space with minimal installation packages installed on the server that is no web or database server packages are installed.
|
||||
|
||||
**2) System Update**
|
||||
|
||||
It always been recommended to keep your system upto date with latest patches and updates, so before we move to the installation on Node, let's login to your server with super user privileges and run update command.
|
||||
|
||||
# apt-get update
|
||||
|
||||
**3) Installing Dependencies**
|
||||
|
||||
Node JS only requires some basic system and software utilities to be present on your server, for its successful installation like 'make' 'gcc' and 'wget'. Let's run the below command to get them installed if they are not already present.
|
||||
|
||||
# apt-get install python gcc make g++ wget
|
||||
|
||||
### Download Latest Node JS v4.0.0 ###
|
||||
|
||||
Let's download the latest Node JS version 4.0.0 by following this link of [Node JS Download Page][1].
|
||||
|
||||
|
||||
|
||||
We will copy the link location of its latest package and download it using 'wget' command as shown.
|
||||
|
||||
# wget https://nodejs.org/download/rc/v4.0.0-rc.1/node-v4.0.0-rc.1.tar.gz
|
||||
|
||||
Once download completes, unpack using 'tar' command as shown.
|
||||
|
||||
# tar -zxvf node-v4.0.0-rc.1.tar.gz
|
||||
|
||||
|
||||
|
||||
### Installing Node JS v4.0.0 ###
|
||||
|
||||
Now we have to start the installation of Node JS from its downloaded source code. So, change your directory and configure the source code by running its configuration script before compiling it on your ubuntu server.
|
||||
|
||||
root@ubuntu-15:~/node-v4.0.0-rc.1# ./configure
|
||||
|
||||
|
||||
|
||||
Now run the 'make install' command to compile the Node JS installation package as shown.
|
||||
|
||||
root@ubuntu-15:~/node-v4.0.0-rc.1# make install
|
||||
|
||||
The make command will take a couple of minutes while compiling its binaries so after executinf above command, wait for a while and keep calm.
|
||||
|
||||
### Testing Node JS Installation ###
|
||||
|
||||
Once the compilation process is complete, we will test it if every thing went fine. Let's run the following command to confirm the installed version of Node JS.
|
||||
|
||||
root@ubuntu-15:~# node -v
|
||||
v4.0.0-pre
|
||||
|
||||
By executing 'node' without any arguments from the command-line you will be dropped into the REPL (Read-Eval-Print-Loop) that has simplistic emacs line-editing where you can interactively run JavaScript and see the results.
|
||||
|
||||
|
||||
|
||||
### Writing Test Program ###
|
||||
|
||||
We can also try out a very simple console program to test the successful installation and proper working of Node JS. To do so we will create a file named "test.js" and write the following code into it and save the changes made in the file as shown.
|
||||
|
||||
root@ubuntu-15:~# vim test.js
|
||||
var util = require("util");
|
||||
console.log("Hello! This is a Node Test Program");
|
||||
:wq!
|
||||
|
||||
Now in order to run the above program, from the command prompt run the below command.
|
||||
|
||||
root@ubuntu-15:~# node test.js
|
||||
|
||||
|
||||
|
||||
So, upon successful installation we will get the output as shown in the screen, where as in the above program it loads the "util" class into a variable "util" and then uses the "util" object to perform the console tasks. While the console.log is a command similar to the cout in C++.
|
||||
|
||||
### Conclusion ###
|
||||
|
||||
That’s it. Hope this gives you a good idea of Node.js going with Node.js on Ubuntu. If you are new to developing applications with Node.js. After all we can say that we can expect significant performance gains with Node JS Version 4.0.0.
