最近Stack Overflow上有一群讨厌perl的人，所以我想我应该把我的“关于你最喜欢的语言你讨厌的五件事”的问题带到Stack Overflow上。拿你最喜欢的语言来说，告诉我你讨厌它的五件事。这些可能只是让你烦恼的事情，承认的设计缺陷，公认的性能问题，或任何其他类别。你只需要讨厌它，它必须是你最喜欢的语言。
不要拿它和其他语言比较，也不要谈论你已经讨厌的语言。不要用你最喜欢的语言谈论你喜欢的事情。我只是想听到你讨厌但能容忍的东西，这样你就可以使用所有其他的东西，我想听到你希望别人使用的语言。
每当有人试图把他们最喜欢的语言强加给我时，我就会问这个问题，有时是面试问题。如果有人找不出他最喜欢的工具的5个缺点，那他对它还不够了解，不能提倡它，也不能利用它赚大钱。他还没有在足够多的不同情况下使用它来充分探索它。他把它作为一种文化或宗教来倡导，这意味着如果我不选择他最喜欢的技术，我就错了。
我不在乎你用什么语言。不想使用特定的语言?那就不要。你通过尽职调查做出了明智的选择，但仍然没有使用它?好吧。有时正确的答案是“你有一个强大的编程团队，有良好的实践和丰富的Bar经验。改成Foo是愚蠢的。”
This is a good question for code reviews too. People who really know a codebase will have all sorts of suggestions for it, and those who don't know it so well have non-specific complaints. I ask things like "If you could start over on this project, what would you do differently?" In this fantasy land, users and programmers get to complain about anything and everything they don't like. "I want a better interface", "I want to separate the model from the view", "I'd use this module instead of this other one", "I'd rename this set of methods", or whatever they really don't like about the current situation. That's how I get a handle on how much a particular developer knows about the codebase. It's also a clue about how much of the programmer's ego is tied up in what he's telling me.
憎恨并不是衡量人们了解多少的唯一尺度，但我发现它是一个相当不错的尺度。他们讨厌的事情也让我知道他们对这个话题的思考有多好。
我知道我迟到了，但恨是永恒的!
Java
Runtime.exec(). So, if I don't manually clear the STDOUT and STDERR buffers, my code will hang? Wow. Die, plz.
Null Pointer Exceptions. Responsible programming means I have to treat most objects like they're unexploded bombs, which is kind of a pisser in an object-oriented language. And when the inevitable happens I kinda need to know which object blew up in my face, but Java apparently feels telling me would be cheating.
File I/O. Why do I have to jump through this many hoops to read a dang text file? And when copying files, I have to funnel the source file into my code and manually handle the output byte buffer? You're serious?
Primitives vs. Primitive Wrappers. Note that Java now has a number of features that allow you to treat primitives and their wrapper objects as interchangeable in some places, but not in others; don't worry, the compiler will let you know which is which. This feels like a hack to work around a fundamentally broketastic design decision. And it is. (EDIT: Actually, the compiler is a much crappier safety net than I thought, particular when doing equality checks. If `a` and `b` are integers, `a == b` is guaranteed to behave as expected only if at least one of them is of type `int`. If they're both type `Integer`, then that statement will do what you think only if the two numbers are between -128 and 127. `Integer a = 1000; Integer b = 1000; return a == b;` will return `false`. Really.)
XML. I have this dirt-simple little XML file I need to create and I have to do what?
