我正在对初级(也许是高级)软件工程师所犯的常见错误和错误假设进行一些研究。

你坚持时间最长、最终被纠正的假设是什么?

例如,我误解了整数的大小不是标准的,而是取决于语言和目标。说起来有点尴尬,但事实就是这样。

坦率地说;你有什么坚定的信念?你大概坚持了多长时间?它可以是关于一种算法、一种语言、一个编程概念、测试,或者任何关于编程、编程语言或计算机科学的东西。

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.

我最近才发现在Hello World中执行了超过一百万条指令!我写的c++程序。我从来没有对像一条cout语句这样简单的东西有过如此高的期望

软件工程师总是诚实地告诉你他们现在在做什么,或者过去对你的软件做了什么。

这很尴尬,但很长一段时间以来,我一直认为嵌套方法调用或进行多个方法调用比在c#中创建一个变量来存储每个方法调用的值更节省内存。

临时的解决方案不是永久的解决方案 或者换句话说:变通办法不是永远的:))。

代码越少越好。现在我知道,有时候如果代码行数更多,就更容易阅读/理解,这是值得的
