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。

C#

Cannot create a reference (var &t = struct) No local scope destructors (IDispose comes close but its not the same) ToString, i almost dislike that every object has it but it turns out i dislike everything using it like string.format does. I rather have things that accepts a certain type (like ints, floats, text, chars only). So instead of passing in any object i need to pass in something with a implicit typecast or interface. I ended up writing something like this to safely escape text for html which worked great. Cannot use a virtual typecast (blah)obj; does not work if obj does not inherit/has an interface of blah. Simple workaround is to supply an interface with a convert function. Has no local creation. Instead of writing var o = new Item(); i would like to write (something like) Item o() (with an automatic dispose if it has one).

没有静态推断 就像在哈斯凯尔发现的一样。这 会导致运行时错误和一个 有认真写代码还是使用 透析器(1)发现 差异。动态类型是 慢的:也被认为是慢的; 与C、Java等语言相比,它几乎是未知的; 的lists(3)模块有时相当精简 我缺少用于列表处理的有用函数 (就像在数据。例如Haskell中的List); 让我在每句话的结尾都加上 在从句中,和。最后是后者。

Python 3

both tabs & spaces allowed for indentation And you'd think people learn from the past (Makefile). Just pick spaces and forbid tabs. YAML got it right. lack of popular third-party libraries The standard library is great, but a lot of what makes Python 2 so powerful lies in the third-party realm. Python 2 got this right :-). IEEE floats Floating points in programming languages are confusing because they're different from the way we use them in math. Instead, the number operations should be viewed as expressions that are only converted to a decimal point format when needed (i.e. printing to a screen). Maple and Mathematica did this right I think. the character set for identifiers is too restricted list.empty? is better than list.is_empty or even len(list) != 0. Similarly, process.kill! would be better than process.kill. Ruby and lisp got this right. when calling a function you must always write parentheses It would be nice if we could omit them in unambiguous cases. How is it again? dict.items or dict.items()? Ruby got this one right, too.

帕斯卡对象:

There's a lot of jumping back and forth in the file you're editing since the interface and implementation are split into two parts but still jammed into the same file. Dynamic indexing of arrays, strings start at 1, you specify the starting index when declaring fixed arrays and dynamically allocated arrays always start at 0. Classes and objects (not to speak of interfaces) are bolted on top of the language and among other things can't be stack allocated like records can. When calling functions without parameters the () are optional, leading to a lot of pain when you are dealing with function pointers or trying to refer to the result of a function using the function name. Parameter lists can't handle fixed array types or function pointer types without external type definitions.

这仅仅是一种语言,一个标准库的遗憾借口,而脆弱的IDE应该有自己的列表。

我的母语……虽然它听起来比克林贡语更美,但它是一个语法地狱……

conjugations: even regular verbs have different forms for each person and time (with few exceptions)... Example: I see, you see, he/she/it sees, we see, you see, they see translates into: Ich sehe, du siehst, er/sie/es sieht, wir sehen, ihr seht, sie sehen. polite form of address: equals 3rd person plural, used to equal 2nd person plural in the middle age... I really hate the concept of distinguishing between "Du" and "Sie" for my philosophy is that each human being should be considered equal in the amount of respect for it deserves (I mean, what are swear words for, hm?) punctuation: show me a language that uses more commas regularly! missing suitable words: eg. there's no real German equivalent of "convenience" or any derivate of this word... in almost every case you just can't translate it into another German word and keep the meaning... instead you would have to make up a whole subset to describe it somewhat adequate... Anglicisms and Denglish: Sure, the English language has "Kindergarten" or "Poltergeist" and what not but the German language is overflowing with Anglicisms nobody needs... Even worse: We redefine some words we adopt, eg. in German "Handy" means a cell phone and has nothing to do with the adjective it is in English... There are influxes on grammar as well, leading to "Denglish" expressions (see linked article at Wikipedia) There's more, but I don't want to exaggerate this and those are my personal Top5 of what I hate about the German language...

但这只是因为VB6毒害了整整一代程序员

我在一个曾经是VB6商店的VB . net商店工作,而在这里工作的每一个曾经是VB6开发人员的人都顽固地拒绝学习任何关于. net的知识。他们编写的代码就像VB6一样,他们的应用程序就像VB6应用程序一样糟糕。我的老板非常不鼓励使用LINQ,因为她担心其他人很难理解,这是事实,因为没有人想要理解它。

我认为如果微软只使用c#,我们会过得更好,这让我很难受,因为我认为花括号远不如VB的冗长结束语句。
