卷二，讨论如何在Octopress中使用中文分类标签。

卷一，介绍在Octopress中添加 Table of Contents (ToC) 的方法。

维护长博客的时候，如果加上一个目录表 (Table of Contents)，会令读者对文章结构有一个清晰的把握。基于Octopress的博客系统，有两种常见的创建目录表的方式：基于 kramdown¹ 的实现，以及基于 jQuery 插件的实现。前者基本上不需要配置，仅要求把默认的 Markdown parser 改为 kramdown 即可。后者则需要对系统进行相对较多的修改。

Blog闲置了许久，好一段不堪回首。重做了新Theme，加了一些plugin（测试页），准备拾笔再写。先慢慢把Wordpress上的文章搬过来吧（半自动化的过程～）。

自打从Yihui Xie那里听说了Jekyll，并照着Jekyll Bootstrap折腾了一番，便喜欢上了这个静态网站构建系统。不久从Lucifr看到Octopress这个变身版的Jekyll，于是就更加要齐齐苦苦了。Octopress依赖于Ruby 1.9.2+，所以这里介绍一下如何用Ruby Version Manager (RVM)。

万事开头难，一篇杂乱的开场白。

本欲在开场中矫揉造作一番，可提起笔来却不知道写些什么。一通挣扎，不禁释然，还是顺其自然，随意写些东西吧，于是有了这个《乱弹》。

How to draw a Bode plot? Well, the answer seams easy. If you have a  MATLAB distribution with Control System Toolbox, you can do this using just a single command, for example,

1

bode(tf(4, [2, 1, 0]));

Indeed, MATLAB integrates so many powerful tools that make scientists and engineers’ lives easier. However, this is not the end of our story. Yes, the figure created in MATLAB looks really, really ugly. If you want a publishable quality figure, which includes more colors, more line styles, more elegant annotations and even more, the mathematical equations, you will feel utterly disappointed in the MATLAB’s plotting ability.

So what is the solution?

Some screenshots of the ACSE Teaching & Testing system.

I’ve recently been asked to design a new testing system (toolbox) for the first year students of ACSE. The purpose is to create a easy-to-use Matlab GUI to help the student to fulfil a self-testing task.

After a few days work, I got my first GUI prototype (see below) which has dark background and light foreground.

坑，不填了，当然Emacs依然是神器，我时而还用它。
