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。

当我在TI-83上编程时,我认为你不能给变量赋值。因此(忽略这是C代码,不是TI-BASIC)而不是编写
c = c + 1;
我会写
d = c + 1;
c = d;
当我学习+=和++时,我惊呆了。

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.
html元素id和name属性是可以互换的。
事实证明,带有'name'属性的元素是相关的/被使用的。引用post等和'id'属性用于DOM引用。
“这次会成功的”
@Kyralessa: It's worth noting that on most processors, in assembly/machine language, it's possible for functions to return someplace other than their caller while leaving the stack in good condition. Indeed, there are a variety of situations where this can be useful. One variation I first saw on the 6502, though it works even better on the Z80, was a print-message routine where the text to be printed immediately followed the call instruction; execution would resume after the zero terminator (or, as a slight optimization when using the Z80, at the zero terminator, since letting the zero byte be executed as a NOP would be cheaper than trying to avoid it).
有趣的是,在许多现代语言中,函数都有一个正常的退出点(将在调用之后恢复执行),但也可以通过抛出异常退出。即使在C语言中,也可以使用setjmp/longjmp来模拟这种行为。
那当断点有效时,谁还需要JUnit测试?(在调试模式下测试应用程序时)。后来我意识到为什么....
