用mysql把书上代码操作了一遍，内容比较基础，实际上需要记得内容不是很多.这是一本sql的入门剧集，后面的存储过程，事务处理，游标，索引，触发器等基本等于没讲，只是了解了一下，要想深入需要补充其他知识，但是这部剧对新手很友好，学起来比较轻松

关于商战的一本剧，但是台词真的没有什么亮点，看了不到一半就看不下去了，也许是我没有get到里面的点吧！
权倾朝野的张居正，人上人的万历皇帝，一团和气首辅申时行，廉洁不阿的海瑞，天才将领戚继光还有思想矛盾的李贽。这群人生活于万历年间，或多或少他们在那个时代都有着改变时局的大小能力，然而，最后却都逃不开社会形态的限制，被时代狠狠的摁倒。有时候不禁为他们唏嘘，同时也在思考这样一个问题，思想被时代所限制，人力真的在社会形态面前毫无抵抗力，那是否是要学着万历皇帝一般躺平接受时代的淘汰？还是学着张居正，李贽一般即使名裂身败也去试？也许不管如何选择，历史滚动的浪潮最终还是会把所有选择都淹没，留下来的也只是作为后人评判研究的材料罢了。
有良心有血性的人在这种国家机器里是很难被包容的。 尔虞我诈君臣互相演戏试探掌控人心，是很扭曲人性的。
我看到了霍金不断追求真理，不断打破自己的认知和理论，科学求真的态度和方法，同时客观地谈论宗教和上帝，最终引导读者思考并建立科学的世界观。
学到了，养足精力，规律生活，慢工出细活，生活处处是健身，处处是学问
#剧评# 2190 Express Male 因为很吓人，被迫连夜看完。文风很……纪实？讲了很多少年的琐碎心事。 并不是像简介说的那么简单，少年拯救世界……算少年奇幻漂流记？ 其间的各种设定看着还是有点费脑，但总体大概是明白了。打算好好的把《Express Male》补完。 总体来说，可以一看
