Algorithm Introduce

What is a good Algorithm? (Cite from: Brian C. Dean )

• Always terminates and produces correct output.
• Make efficient use of computational resources. Minimizes running time, memory usage, processors, bandwidth, power consumed, heat produced.
• Is simple to describe, understand, analyze, implement, and debug

View C++ as a federation of Languages

In the begining, C++ was just C with some object-oriented features tacked on. c++ = C with classes. 但是到了后来，C++就包含了很多复杂的事物，我们在使用C++的时候可以将其看成四种不同的使用方式。

How Internet News Censorship in China Silences the People’s Song

This is a thesis when I studied in the ELS.

Introduce

Last month, my friend Carrier went back to China from the United States after she had been living the United States for more than three years. She complained to me about the Internet in her house but not because of the speed of the Internet. She found that the Google Mail and Facebook were inaccessible when she wanted to access to Google Mail to receive some email from her boss and to contact friends through Facebook. As a computer engineer in China, I have never been puzzled by this since I can use a lot of ways to access to Google or Facebook. Is it challenging to access to Google and Facebook in China? Curiosity pushed me to investigate further. When I asked my parents and some high school classmates about whether they knew how to avert the government blocking access to Google, most of them said that they didn’t know how to access to Google in China even though they knew the Google search engine is most famous in the world. After doing some research, I found that blocking Google is only one of many blocking events involving Internet news censorship in China.

Introduce

常用的三个命令：

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

apt-get是某些linux发行版使用的一个“包管理器”（还有别的发行版使用yum等，以及brew等其他平台上的包管理器，工作原理类似）。包管理器的作用是从源（Source）服务器那里下载最新的软件包列表，然后在你需要安装某个软件包（apt-get install）的时候从列表里面查询这个软件包的版本信息、系统要求、翻译、依赖项（该软件正常运行必须安装的其它软件）并且添加到同时安装的列表里面，再查询所有安装列表里面的软件包的.deb文件下载地址，最后批量下载，自动分析安装顺序然后安装完成。

Introduce

What is the Cloud Computing?

Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, servers, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

Git command

Branch operation

1. Background: We often want the copy the master branch(or other branch) to develop a new function.

$git checkout master  //Change to the master branch or which branch you want to copy
$git pull                   //从远端拉取最新版本
$git checkout -b NewBranch  //Switched to a new branch 'NewBranch'
$git push origin NewBranch  //新建分支NewBranch到远端
