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。

Windows中的线程很便宜。
事实证明，这只是部分正确。线程有一定的开销，需要自己的地址空间，在那里它可以生存和快乐。因此，如果我发现自己在一个应用程序中处理数十个线程，我会问自己如何将所有内容简化并整合到更少的线程中。

:
for (int i = 0; i < myObj.variable; i = i + 1)
优化为:
int j = myObj.variable;
for (int i = 0; i < j; i = i + 1)
哇，当我意识到它们每次都在运行时，我停止在j的地方放入函数调用!
原因:
for (int i = 0; i < myObj.variable; i = i + 1){
if (function_argument == NULL){
myObj.variable++;
} else {
printf("%d", myObj.variable);
}
}
并不等同于:
int j = myObj.variable;
for (int i = 0; i < j; i = i + 1){
if (function_argument == NULL){
myObj.variable++;
} else {
printf("%d", myObj.variable);
}
}
任意的例子，但是您可以看到优化将如何改变执行。
人们实际上关心所使用的技术(开源/闭源)。
常见的错误假设:“代码质量是次要的”。 更糟糕的假设是:“代码质量一点都不重要。”
代码质量是一个非常宽泛的概念。我在这里已经详细讨论过了。
通过学习一门精确的科学，我不需要提高我有限的社交技能。
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……
