书很薄，在图书馆瞄了一下，知识点不多。
基本上第二章基本讲完，其他讲解都是一些擦边的，兼容性，安全性，……
可以总结为如下：

Scrapy 是什么？

Scrapy是一个基于Python的高级爬虫框架，只需要简单的配置就可以实现你大大的需求。

为什么要介绍Scrapy，内容时代了，没有内容再好看的网站，那又有什么用呢？

Learn bash shell, by interest or needed. what is your reason to learn the shell? I think the best reason is that what you need is what you learn.

A few days ago, I rewrite the project css to sass, so I need to rename the css. So I brought out a question, how to "Rename multiple files shell"? To people, solving problems with search engine is the method of least time. I am no exception, I encountered the same problem, and find out the answer in stackoverflow https://stackoverflow.com/questions/6911301/rename-multiple-files-shell.

Good news, my blog had Upgrade from Octopress 2.x to Jekyll 3.x. It is not difficult to do this, if you follow me step by step.

As you know, Octopress 2.x is based on Jekyll 2.x. so "Upgrade from Octopress 2.x to Jekyll 3.x" mean that upgrading Jekyll 2.x to Jekyll 3.x.

Preface

docs.w3cub project is based on open source. we use jekyll system to rewrite and hosted on Github Pages. This project continued for several months and written in my spare time.

As you know, all pages are static. we think that this would be more fast than using backend router. The most important thing is that Github Pages is free. we also thought about using frondend history router to rewrite this project, but Github Pages don't support the nginx rule. However we have permission to use 404 page, but useing the 404 page as the frontend router is very crazy idea. So at last we use the jekyll system to generate the static pages.

Autocompletion is never an entirely solved problem. Can anyone really say what on earth a user typing "uni" into a country input field actually intends to select? It could match any of these:

自动完成一直都是一个没完没了的问题。谁能准确地说出当一个地球人在一个国家输入框输入“uni”打算选什么？可能会出现以下情况：

• Tanzania, [U][n][i]ted Republic of
• [U][n][i]ted Arab Emirates
• [U][n][i]ted Kingdom
• [U][n][i]ted States
• T[u][n][i]sia

Of course, it’s probably not the last one, but that right there is a human intuition that we often forget to instil into these UI interactions.

当然，这可能不是最后一个，但人类的直觉通常会忘记灌输这些UI交互。

常用命令（Action）：

list        :: show currently installed rubies, interactive output.
install     :: install one or many ruby versions
use         :: setup current shell to use a specific ruby version
