糟糕的命名习惯:总是不可原谅的。

是的，不要总是认为你的方式更好……这可能很困难，但必须保持客观性。

I've had an experience with a coder that had such horrible naming of functions, the code was worse than unreadable. The functions lied about what they did, the code was nonsensical. And they were protective/resistant to having someone else change their code. when confronted very politely, they admitted it was poorly named, but wanted to retain their ownership of the code and would go back and fix it up "at a later date." This is in the past now, but how do you deal with a situation where they error is ACKNOWLEDGED, but then protected? This went on for a long time and I had no idea how to break through that barrier.

Global variables: I myself am not THAT fond of global variables, but I know a few otherwise excellent programmers that like them A LOT. So much so that I've come to believe they are not actually all that bad in many situations, as they allow for clarity, ease of debugging. (please don't flame/downvote me :) ) It comes down to, I've seen a lot of very good, effective, bug free code that used global variables (not put in by me!) and great deal of buggy, impossible to read/maintain/fix code that meticulously used proper patterns. Maybe there IS a place (though shrinking perhaps) for global variables? I'm considering rethinking my position based on evidence.

我建议对这个问题采取积极的态度。与其指责你的同事使用糟糕的风格，不如就风格和评论准则提出一些建议，让你的整个团队都能遵循。

例如，如果你主要是一个。net商店，建议坚持微软的c#风格和注释指南，因为这将使你更符合社区的标准实践。

您还可以指出一些遵循统一代码风格的例子——例如，如果不熟悉代码库的人查看了它，他们就不必破译多种风格。可以这样想:如果你正在读一本书，很容易看出每一章都是由不同的人写的，你会在读了几章后感到困惑吗?

我认为重要的是不要用消极的方式批评你的同事。最好是向人们推销改变的好处，这比说服他们写的是糟糕的代码要容易得多。

他们可能也认为你的风格很糟糕。让团队一起讨论一套一致的编码风格指南。同意某事。这是否适合你的风格并不是问题，选择任何风格只要它是一致的才是重要的。

我总是说‘这就是我要做的’。我不会试图教训他们，告诉他们他们的代码是垃圾，而只是给他们一个不同的观点，希望能向他们展示一些明显更整洁的东西。

在他面前重构他的代码，并显示两个版本之间的差异。他肯定会喜欢的。

首先，我会注意不要太快下结论。有些代码很容易被认为是坏的，尽管可能有很好的理由(例如:使用带有奇怪约定的遗留代码)。但让我们暂时假设他们真的很糟糕。

你可以建议建立一个基于团队输入的编码标准。但是你真的需要考虑他们的意见，而不仅仅是强加你对好的代码应该是什么样子的看法。

另一种选择是把技术书籍带进办公室(《代码完成》、《有效的c++》、《实用的程序员》……)，并主动把它借给别人(“嘿，我用完了，有人想借吗?”)
