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。

在c++中，很长一段时间我都在想编译器在给纯虚方法定义时拒绝你。
当我意识到我错了时，我很吃惊。
很多次，当我告诉别人为其抽象类提供其纯虚析构函数的默认实现时，他/她都用大大的眼睛看着我。我知道接下来会有一场长时间的讨论……这似乎在c++初学者中是一个普遍的信念(我认为我自己也是如此)。我目前还在学习!)

假设我要使程序100%完成，没有错误，并报告它为“完成”。有时，公司想要在程序存在很多漏洞时发布该程序，以抢占市场份额。
我一直认为，任何为任何语言编写任何代码的人都会使用编辑程序。
I was working with a client of mine who had me on mostly as support and to write some of the more complex things for him. Well one day he messed up a file, big time. He accidentally saved over three hours worth of his own work, and when I asked him why he didn't save more often he replied with, "because I wasn't done". Naturally, this was not an acceptable answer, and I poked and prodded a little further. I eventually came to find out that he he has never used any editing program, EVER! Not even notepad.exe! He had been using an online CPanel editor for files! It didn't even have a 'Find' function. He couldn't ever save until he was done because he was editing the live file on the site!
不用说，我很惊讶，他至今仍在使用CPanel编辑器……
用汇编语言进行优化=重写。
When I first really understood assembly (coming from BASIC) it seemed that the only way to make code run faster was to rewrite it in assembly. Took quite a few years to realize that compilers can be very good at optimization and especially with CPUs with branch prediction etc they can probably do a better job than a human can do in a reasonable amount of time. Also that spending time on optimizing the algorithm is likely to give you a better win than spending time converting from a high to a low level language. Also that premature optimization is the root of all evil...

这绝对不是真的，即使P2缺陷有时也会被打开。
