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。

我讨厌Java(目前它是我最喜欢的语言)的五个方面,排名不分先后。

As much as I am a fan of Java Generics, there are a lot of oddities that arise from the way it was designed. As such there a myriad of annoying limitations with generics (some of which are the result of type-erasure). The way Object.clone() and the Cloneable interfaces work is totally broken. Instead of taking the high-road and making everything an object (a.la. SmallTalk), Sun wimped out created two distinct categories of data-types: Objects and primitives. As a result there are now two representations for fundamental data types and wierd curiosities such as boxing/unboxing and not being able to put primitives in a Collection. Swing is too complex. Don't get me wrong: there's a lot of cool stuff one can do with Swing but it is a great example of over-engineering. This final complaint is equally the fault of Sun and those whom have written XML libraries for Java. Java XML libraries are way too complicated. In order to simply read in an XML file, I often have to worry about what parser I am using: DOM or SAX? The APIs for each is equally confusing. Native support in the language for easily parsing/writing XML would be very nice. java.util.Date sucks. Not only is it unnecessarily complicated but all the useful methods have been deprecated (and replaced with others that increase complexity).

我讨厌Python的地方:

没有编译器 它没有被认真对待

Python让我恼火的地方:

(自我, 没有私人 打破兼容性

我讨厌PHP的五个方面:

“按预期工作”,而这显然是一个bug 没有转到 有bug的引用(foreach $arr => &$val…Foreach $arr => $val) 没有多重继承 没有一个编译器能够真正工作,而不需要向黑暗之神牺牲一只羔羊

Python:

没有分隔符表示块的结束会导致歧义,这样自动缩进就不能处理格式不佳的代码。 没有宏(修饰符不算) 没有像haskell的cabal或perl的CPAN那样的库自动获取 不能声明变量const(是的,可以自己定义变量,但是…) 元编程被削弱 差点忘了全局解释器锁

Java:

很不一致。 图形api有时使用起来很痛苦 nullpointerexception不会告诉你什么是null 我写的程序有时不能在不同的JVM上运行,这是一个巨大的痛苦,与Java的“一次编写,随处运行”语句相矛盾。 Swing并没有达到应有的效果。

EL -表达式语言,${…}和#{…JSF 2.0 Facelets用于从底层Java代码中提取数据。

All the fun things, like method calls with parameters and annotation based naming is only present in the EL in Java EE 6 which is only available in Glassfish v3. It is a royal pain to 1) get the right jars for an earlier Servlet 2.5 container, and 2) getting them to work without interfering with any previous implementation available in the container. Having only an earlier version of JSF like 1.2, takes away the method calls and leave you to work with f:setPropertyActionListener - http://weblogs.java.net/blog/2009/07/22/say-sayonara-spal - which, trust me on this, is not very nice. The EL parser has no idea of where the snippet it is to parse and interpret came from, so you tend to give everything an id so you at least can identify which tag made it grumpy. Eclipse gives a warning at every EL method call as it is JSF 1.2. only too.

length属性很容易与length()函数混淆;请改用size() 在选择器字符串中插入变量的语法('" +$。Month + "')臭死了 $(event.currentTarget)并不总是适用于冒泡和捕获 属性语法("[class='foot']")在选择器语法(".foot")不返回任何结果的地方起作用 包含选择器([class~=done])有时会在JavaScript (this.className.search("done") > 0)工作时失败
