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.

通过例子。告诉他们正确的道路。

慢慢来。不要因为他们的每一个小错误就立刻痛斥他们，要从真正重要的事情开始。

以一种非对抗性的方式提出一个更好的选择。

“嘿，我觉得这个方法也可以。你们怎么看?”[用手势表示屏幕上的代码明显更好]

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。

这取决于程序员。有些人实际上喜欢听到“这太糟糕了”，因为他们知道代码很臭，但不知道为什么。

其他程序员需要更多的照顾。我发现告诉他们坏事是好的;“这不是写代码的好方法”，然后是一些指导“这里，看看我们是否这样做，它更可读/更少警告/诸如此类”。建设性的批评是有帮助的;如果你不能说到做到，最好不要评论，即使你知道这是不好的。

唯一一个两种方法都失败的人是一个固执的行政助理，他用VBscript写了大量的宏，一切都是逆向的。她竟然厚颜无耻地告诉我，我对计算机编程一窍不通，我可以向她学习。

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。
