主要介绍可以回测，实盘的量化开发的流程，主要语言是python。
也介绍了量化平台开发中的涉及到的各种坑。
比如如何避免未来函数的回测等。
也涉及到现在流行的机器学习算法在量化交易的应用等。

常规PID模糊PID神经网络PID控制效果比较-success.rar最近做毕设，题目是智能励磁，做了个模糊PID和神经网络PID励磁控制，说白了，和励磁没任何关系，就是对一个三阶模型进行控制，现在与大家分享下。
其中常规PID和模糊PID是用仿真实现的，而神经网络PID是用编程实现的。
现已附上GUI和mdl文件。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
