[1.1]Knowledge that should be prepared

Actually, there are a huge amount of knowledge we need to learn. So I hope you don't be scared. It's OK.

Besides, I have to say that most of the tutorial articles are written in English. And this is also one of the reasons that I write this article in English.

For each area we have to learn, I will paste a commanding url to learn it.

Here is the list:

1.To control the basic Linux commands : http://www.linuxcommand.org/  Luckily, it has a Chinese version(I don't know whether the url is stable):http://billie66.github.io/TLCL/book/index.html (plan has changed , so this one is deleted.)

2.To know some basic knowledge about webpage (don't need to grasp thoroughly, although thorough grasp is better): http://www.w3schools.com/  Luckily, this one also has a Chinese version : http://www.w3school.com.cn/  But as for the Chinese version, I will recommend this one : http://www.runoob.com/

3.Database knowledge is also important for a search engine : http://www.quackit.com/sqlite/tutorial/ Chinese tutorial: http://www.runoob.com/sqlite/sqlite-tutorial.html

4.Learn Python : https://docs.python.org/2/tutorial/  For Chinese version, I recommend this one : 廖雪峰的python教程

5.Learn Django (for this one, I only recommend English documentation): https://docs.djangoproject.com/en/1.10/ But if you really want a Chinese version, I will recommend this : 自强学堂

6.Basic knowledge of using github.

Last, I still want to say that technology is not the core of this project. What matters most is thoughts. In another word, what we are going to do is not to use technology to combine the results of several existing search engine like a machine. What we really need to do is to create a pattern that can sort out what children really need from all the colorful results. In a way, it's artificial intelligence.
