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，要成为一名优秀的程序员，必须了解系统的所有内部工作原理。我很羞愧，因为在开始编码之前，我不知道关于这门语言的一切，比如它的库、模式、代码片段。 我不再那么天真了。

这个:
SomeClass object(initialValue);
这:
SomeClass object = initialValue;
保证在c++中是等价的。我认为第二种形式肯定会被解释成第一种形式。并非如此:请参阅c++初始化语法。
如果我有一个像ML或Haskell中那样强大的静态类型系统，我应该使用它来编码尽可能多的不变量。只有有了经验，我才知道有时最好让不变量是动态的。
我最大的先入之见是，我将被允许以我想要的方式编程。当然，后来我离开了大学，进入了一家拥有荒谬框架、规则和程序的公司，这不仅意味着我不能以自己想要的方式编程，而且意味着我编程得很糟糕。
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.
在学校里，你被教导编程是“读取输入，处理数据，写输出”。实际上，很少有处理步骤——大多数编码只是“读取输入，输出”。
一般来说，它要么是“从用户读取，写入数据库”，要么是“从数据库读取，显示在屏幕上”。这两种情况涵盖了大约95%的工作。
