使用一个变量实现线性回归，以预测餐馆的利润。 使用梯度下降法，假设 h (x) 由线性模型给出 ，定义代价函数为 。线性回归的目标就是要最小化这个代价函数。(To get started with the exercise, you will need to download the starter code and unzip its contents to the directory where you wish to complete the exercise. If needed, use the cd command in Octave/MATLAB to change to this directory before starting this exercise.)

一款基于HTML5 CSS3的瀑布流布局特效，相信瀑布流您已经很熟悉了，这两年流行的一种网页布局效果，它可以横向和垂直布局，本款代码貌似兼顾了两者，看上去更像是一个照片墙特效，点击任意一张小图片，会显示该图片的描述文字，在火狐下效果更好。

通用运行监控平台的设计与实现.将报警与探测分离开来，让“探测”掌握在维护 人员自己手里，使维护人员可以自由使用系统本身的一些探测工具，同时也可自主开应用级探测命令，再通过该监控软件，把所有的探测结果以统一的形式来报警，从而做到灵活通用性，便于运行上实现集中监控。-Common monitoring platform to run the design and implementation. Will be separate from the alarm and detection, so that " detect" rests in the hands of their own maintenance personnel, so that maintenance personnel are free to use the system itself, some of the detection tools, but also to open their own application-level probe command, and then through the monitoring software, all the detection results in a uniform manner to the police, to be flexible and versatile, easy to run on a centralized control.
