Lua是一个轻量级脚本语言，由巴西里约热内卢天主教大学的一个三人研究小组于1993年开发。
它由标准C编成，可通过灵活嵌入应用程序中从而为应用程序提供灵活的扩展和定制功能，几乎在所有操作系统和平台上都能运行。
其主要优势如下：
- 可扩展：Lua脚本可以被C/C++调用，也可以调用C/C++的函数。
- 轻量级：其代码简洁，体积小、启动速度快。
- 其它特性：同时支持面向过程和函数式编程。
由于其良好的可扩展性，许多知名应用和游戏（如 魔兽世界，饥荒）都将其作为嵌入式脚本语言。
其官网为Lua官网，在其上有对Lua特性的更全面、详尽的介绍，一个简明的入门手册，以及免下载的Lua体验页面。

SimpleNES https://github.com/amhndu/SimpleNES
This project provides a simple NES emulator written in C++. You can run some classic Nintendo games like SuperMarioBros with this NES.
I recommend this project because of both its simplicity and profundity. This project includes only less than 30 files, each of which has no more than 1000 lines of codes, which is very suitable for C++ beginners. Despite its simplicity, we can learn a lot about computer system architeture, which is really important for cs majors, including how CPU executes instructions, how the memory is allocated and so on.
