评论越多越好。我总是试图让我的代码尽可能具有可读性——主要是因为我几乎肯定是那个会修复我漏过的bug的人。所以在过去的几年里，我经常会收到一段又一段的评论。

最终，我明白了，有一个点，更多的评论——无论结构多么整齐——没有增加价值，实际上成为一个麻烦的维护。这些天，我采取了目录+脚注的方法，每个人都为此感到高兴。

一个函数/方法应该只有一个出口点。

通过实现客户想要的东西来满足客户——不幸的是，这意味着客户知道他想要什么。

代码行数越多，软件就越好。

我很早就开始学习编程了。那时我14岁左右。我有各种疯狂的想法，但不要问我准确的时间，因为那是很久以前的事了。

Ok, so, I believed for a while that if you use the term synchronize in Java, then Java solves this nasting synchronizing thing for you I believed for at least half a year, likely more, that static typing would improve performance. I believed that freeing something would return memory back to the OS. I believed that malloc calls boil down to checking if there is enough free space on the OS, so malloc would be inexpensive. I thought a long while that Java was built with all the benefits and flaws of the other languages in mind, into a "perfect blend" that would take the best properties of the other languages and reject the mistakes. I vastly overestimated the number of cases where LinkedLists outperform ArrayLists. I thought that NP-hardness was a proof that no INSTANCE could be solved efficiently, which is trivially false, for a while. I thought that finding the best flight-plan on travel agency web sites would take so long because of the "Travelling Salesman Problem", as I proudly chuckled to my relatives (when I was small, alright?!)

还能想出更多。不知道我坚持了多久。对不起。

PS: 啊，好吧，这个被清除得并不慢，但我看到新手时不时地这样做，所以我想你可能会感兴趣:我还认为要存储不确定数量的东西，你需要为每个东西声明一个新变量。所以我要创建变量a1 a2 a3…，而不是使用一个变量a，我将它声明为一个向量。

在编程的头几年，我没有意识到1kbyte在技术上是1024字节，而不是1000字节。我总是有点困惑，因为我的数据文件的大小似乎与我预期的稍有出入。
