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。
当前回答
在很长一段时间里，我认为糟糕的编程是发生在边缘的事情。正确做事是标准。我现在没那么天真了。
其他回答
至少6年来，我一直坚信，每个问题都只有一个解。
完全不知道不同复杂性的多种算法、空间/时间的权衡、面向对象、功能和命令式、抽象级别和无法确定的问题。当那种幸福的天真被打破时，它打开了一个充满可能性的世界，关上了坐下来建造东西的大门。我花了很长时间才弄清楚怎么选一个然后用它来运行。
我在计算机科学课程中所学的Karnaugh地图在编程中永远找不到实际用途。
:
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。
“这次会成功的”
I thought I'd be coding for 8 hours straight. Realistically, I get 4 hours a day of coding, 1 hour for lunch, 1 for coffee breaks, and 2 for screwing around / chit chatting/ stack over and under flowing. Prior to working, I thought that all clients would be idiots and don't know two craps about computers. Boy was I wrong on that one. Sometimes, we get projects by people who can do it better than we can, they just don't have the time to do it. I thought cubicles were bad, Right now I love them :D I actually moved from a door-ed office to a cubicle. I like the openness. All programmers are not athletic. I thought that I was the only one that goes to the gym. Where I work, at least 10 of us go to the gym every day at 5 am. I thought there would be no women programmers. A couple of our leads are ladies.
