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。

以为我是唯一一个会写代码的人……然后当我需要这个例程时，我不记得我做了什么，只是复制/粘贴我自己的代码。
我知道每个人都这么做。

My co-workers were/are producing supposedly bad code because they sucked/suck. It took me a while to learn that I should first check what really happened. Most of the times, bad code was caused by lack of management, customers who didn't want to check what they really wanted and started changing their minds like there's no tomorrow, or other circunstances out of anyone's control, like economic crysis. Customers demand "for yesterday" features because they are stupid: Not really. It's about communication. If someone tells them it everything can really be done in 1 week, guess what? they'll want it in 1 week. "Never change code that works". This is not a good thing IMO. You obviously don't have to change what's really working. However, if you never change a piece of code because it's supposedly working and it's too complex to change, you may end up finding out that code isn't really doing what it's supposed to do. Eg: I've seen a sales commission calculation software doing wrong calculations for two years because nobody wanted to maintain the software. Nobody at sales knew about it. The formula was so complex they didn't really know how to check the numbers.
我的编程如果由我一个人来执行会更快更好。
