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.

与其让他们写代码，不如让他们维护代码。

除非他们不得不维护他们那堆冒着热气的意大利面，否则他们永远不会明白自己在编码方面有多糟糕。

进行代码审查，并从审查你的代码开始。

这将使人们在整个代码评审过程中感到轻松，因为您是通过评审自己的代码而不是他们的代码来开始这个过程的。从你的代码开始也会给他们提供如何做事的好例子。

重要的是激励和指导人们，即使有人明显犯了错误，也要表现出尊重。但是，不仅要有指导的方法，而且要有说明错误就是错误的方法。糟糕的代码应该做得更好。这不是可选的。从主管的角度来看，员工应该知道哪些代码是可以的，哪些是不可以的。它仍然应该以尊重和激励那些负责任的人来改善。

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。

没有人喜欢听别人说他们的工作很糟糕，但任何理智的人都会欢迎指导和避免不必要工作的方法。

有一种教学流派甚至说，你不应该指出错误，而应该专注于做对的事情。例如，与其指出难以理解的代码不好，不如指出他们的代码特别容易阅读的地方。在第一种情况下，你会引导其他人像蹩脚程序员一样思考和行动。在后一种情况下，你会像一个熟练的专业人士一样思考。
