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。

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……

我知道要编写一个合适的web应用程序，当我必须设计在所有浏览器上都能运行的东西时，我很清楚这一点。
分析和性能分析是一回事。
然后我发现，虽然分析器总比没有强，但它包含错误的假设，比如:
只有总量才重要，细节无关紧要 统计精度是定位性能问题的必要条件 测量时间和定位不必要的耗时操作是一回事
这种编程软件需要扎实的高等数学基础。
在我开始编程之前，我总是被告知要成为一名优秀的程序员，你必须精通高级代数、几何、微积分、三角函数等。
十年后，我只做过一次八年级学生做不到的事。
总有一天，我会有一个现实的想法，那就是构建一些重要的代码/系统/什么的需要多长时间。
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...
