Continue from the previous part: Install Ubuntu on VirtualBox (Part 1).
We have already downloaded all the needed softwares and finish the virtualbox installation, so far so good~
Now launch the newly installed virtualbox, let’s …
[Create a virtual machine]
Remember we mentioned that the OS needs to be installed on a physical machine in our last post? Yeah, right now we are gonna to prepare a virtual physical machine, using virtualbox.
The fresh installed virtualbox looks like below:
[Dedication]
To my friend louchx:), welcome to the Unix/Linux world!
[Overview]
Ubuntu is one of the most popular linux distribution nowadays. It mainly focus on usability, accessibility and internationalization, to reach as many people as possible. Refer ubuntu home page and this wiki page for more detail information about ubuntu.
Usually we will need a physical machine to install an OS like ubuntu, but since that’s our first time to install linux, let’s choose another more secure way. We will use a software virtualizer to virtualize a physical machine for us.
VirtualBox is a general-purpose full virtualizer for x86 hardware. According to its official home page, it is now the only professional-quality virtualization solution that is also Open Source Software.
Another choice is VMware, but since it’s not free, that’s not my recommendation here.
So… here we will install ubuntu on virtualbox based on windows hosts.

[Preface]
印象中，security总与convenience矛盾，虽然有时候inconvenience并不总是那么的显而易见。
[Background]
公司的电脑总是会冷不丁的给你surprise，真所谓“重启就会有奇迹”，某次系统reboot后，我惊奇的发现系统在介于BIOS和Boot Loader之间多了个步骤（user experience蛮好，至少有个进度条），然后就是我的linux dual boot不灵了，kernel都没有解压完就卡在那不动了，windows倒是继续能很happy的boot，一刹那顿时觉得好神奇……
系统真正起来后才发现windows多了个软件叫SafeBoot（被McAfee收购后，现在学名McAfee Endpoint Encryption）
别的功能不清楚，一个最醒目的feature是disk encryption，经我测试貌似不是full disk的encryption，只是windows所在的那几个分区被加密了，开机的时候那个进度条应该是在解密（把MBR都改了，好强悍，更强悍的是改MBR连告都不告诉一下，算你狠），加了密然后boot时实时解密，所以windows还能很perfect的boot，linux所在的分区并未被加密，按理来说boot应该不会有问题，但是不知道为啥就是卡在那不动，想来必是boot时的实时解密多此一举了，导致没有加密的硬盘反而无法正确读取，真是you don’t know what you know……

Need a web server and a database engine to run bugzilla, here I choose apache and mysql.
Install apache:
Refer this wiki page for detailed information about apache installation and configuration.
Install mysql:
The above LAMP wiki page also mentions something about mysql installation and configuration, for standalone installation, please refer this wiki page.
Then install bugzilla using:
It requires a bunch of perl modules to be installed too, but some required modules still need to be installed manually (a little weird, why not include all required perl modules into dependencies?)
Make a module check first:
嗯，这是个问题……
在A Byte of Python看到的评论是：
If you’re wondering whether to learn Python 2.x or 3.x, then read this article by James Bennett.
貌似是从语言本身支持string Unicode，然后重组一些standard library啥的（最近老是听到restructuration一词，IT裁人不叫lay off，叫restructuration……我就短短时间内已经被restructure了两次了……），不管了，反正我也不知道2.x啥样，不compatible就不compatible:)
上篇文章中我说Arch发布新版本没啥意义，因为本身就是滚动更新，今天虚拟机里装了一下玩玩，发现安装过程中还是有不少明显改进的，这样看来新版本的发布还是非常有意义的（当然有意义了，否则整出来干嘛:-)……）
首先值得一提的改进应该就是时区时间设置的改进，2008.06版本只有在修改配置文件时让你修改，而且即便正确修改了，也还是会有问题。
新版本里改进的那是相当彻底，一开始安装什么先都不干，一上来就问你是UTC还是localtime，然后就让你输入时区和时间，输完了以后，便会帮你自动修改/etc/rc.conf里的HARDWARECLOCK和TIMEZONE，并且copy一份zoneinfo到/etc/localtime，然后再是prepare hard drive，package什么的，这是非常要赞的，这样安装的好处就是你再也不会碰到我之前文章提到的问题了。

Archlinux放出了新的iso，包括了从2008.06版本以来的usb img版本，
http://ftp.archlinux.org/iso/2009.02/
当然你可以说它没有意义，因为Arch本身就是滚动更新的，我一个
pacman -Syu
就是最新的了.
但其对于新装系统，重装，系统修复等还是有意义的.
PS：事后回头想想，新装，重装估计也没啥意义……，反正每次装完都要更新一把，新的旧的又有啥关系呢？先不重刻了，麻烦……
上篇日志中，我还在一直纳闷抑或欣喜为什么又是星期五的时候，Sunng同学的一个comment一举消除了我的疑问，不是星期五有问题，是我自己有问题，呵呵……
经过一番研究和学习，发现原来Archlinux下仅在/etc/rc.conf里把TIMEZONE设成”Asia/Shanghai”是不够的，还要在/etc/localtime做个软链接给具体的zoneinfo：
这个时候时区应该算是正确设置好了，把硬件时钟再同步回系统来，
这个时候时间又不对了，因为之前我是人为滞后了8小时（当时是负负得正，时间倒正好是正确的，而且平时也不会去关心这个，估计Sunng不说我是不会发现的了:-)），但是现在时区对了，所以现在时间应该正好晚了8小时。

[ Update: Open Explorer 1.3.0 and 1.4.0 were released, the latest version can be downloaded here. ]
Share a recently developed Eclipse plugin:
The idea is simple.
Assume you are already familiar with “Package Explorer” and “Navigator” view in eclipse, which can help us a lot in viewing the directory structure during development.
But have you had a chance to want to open the directories and files there in the system file browser, say “Windows Explorer”?
I usually do, and I almost repeat the same routine everyday (Right click the directory-> Choose Properties -> Copy the Location-> Open Explorer(e.g. “My Computer”) -> Paste the Location -> Enter), which make me feel boring and silly.
