In the early days, most personal computers had a cassette tape interface for loading and storing programs. I did not have a computer at this time but read everything I could get my hands on (mostly magazines) that had anything to do with computers (this was the late 70's - no internet for me). For some reason I was under the impression that programs were executed directly from the cassette tape and that the only reason computers had any RAM was to store variables while the program ran. I figured that when the code had to execute a jump instruction, it would somehow rewind or advance the tape to the correct position and continue from there.

XML名称空间(或者更糟，格式良好)在某种程度上比没有它们要困难得多。

一个非常常见的错误，甚至在W3C!

喂!,

我只是在设计和写代码。

没有需求收集、文档或支持。

欢呼,

我认为我应该尽可能地进行抽象。我的脑袋被这个撞了，因为太多交织在一起的小功能。

现在我试着让事情尽可能的简单和分离。重构使事物抽象比预测需要如何抽象要容易得多。

因此，我从开发规则它们的框架转移到完成工作的功能片段。从来没有回头，除了当我想起那段时间，我天真地认为我会是那个开发下一个大东西的人。

我想说的是，将日期的year元素存储为2位数字是一种困扰整个一代开发人员的假设。在千年虫问题上浪费的钱是相当可怕的。

在不浪费字节和CPU周期的情况下编写高效的程序是非常重要的。

但随着经验的积累，它与字节或CPU周期无关，它与你的思想流有关，连续的，不间断的，就像一首诗。

本质上，不要太努力。
