Null引用应该从OO语言中删除

从Java和c#的背景来看，从一个方法中返回null来表示失败是很正常的，我已经得出结论，null会导致很多可以避免的问题。语言设计者只要从代码中消除空引用，就可以删除与nullrefernceexception相关的一整类错误。

Additionally, when I call a method, I have no way of knowing whether that method can return null references unless I actually dig in the implementation. I'd like to see more languages follow F#'s model for handling nulls: F# doesn't allow programmers to return null references (at least for classes compiled in F#), instead it requires programmers to represent empty objects using option types. The nice thing about this design is how useful information, such as whether a function can return null references, is propagated through the type system: functions which return a type 'a have a different return type than functions which return 'a option.

MS Access*是一个真正的开发工具，专业程序员可以毫无羞耻地使用它

仅仅因为某个平台吸引了自认为是程序员的黑客和秘书，就不应该玷污这个平台本身。每个平台都有其优点和缺点。

那些抱怨某些平台或工具或将其贬低为“玩具”的程序员更有可能对自己的手艺知之甚少，而不是他们的自我意识所说服的那样。对我来说，听到一个程序员抨击任何他们自己没有广泛使用过的环境是一种过度自信的表现。

生成文档良好的代码比生成文档不良的代码花费的时间更少

When I say well-documented I mean with comments that communicate your intention clearly at every step. Yes, typing comments takes some time. And yes, your coworkers should all be smart enough to figure out what you intended just by reading your descriptive function and variable names and spelunking their way through all your executable statements. But it takes more of their time to do it than if you had just explained your intentions, and clear documentation is especially helpful when the logic of the code turns out to be wrong. Not that your code would ever be wrong...

I firmly believe that if you time it from when you start a project to when you ship a defect-free product, writing well-documented code takes less time. For one thing, having to explain clearly what you're doing forces you to think it through clearly, and if you can't write a clear, concise explanation of what your code is accomplishing then it's probably not designed well. And for another purely selfish reason, well-documented and well-structured code is far easier to dump onto someone else to maintain - thus freeing the original author to go create the next big thing. I rarely if ever have to stop what I'm doing to explain how my code was meant to work because it's blatantly obvious to anyone who can read English (even if they can't read C/C++/C# etc.). And one more reason is, frankly, my memory just isn't that good! I can't recall what I had for breakfast yesterday, much less what I was thinking when I wrote code a month or a year ago. Perhaps your memory is far better than mine, but because I document my intentions I can quickly pick up wherever I left off and make changes without having to first figure out what I was thinking when I wrote it.

这就是为什么我能很好地编写文档——不是因为我觉得编写适合展示的漂亮代码是一种崇高的使命，也不是因为我是一个纯粹主义者，而只是因为端到端让我在更短的时间内发布高质量的软件。

宏，预处理器指令和注释是邪恶的。

每个文件只使用一种语法和语言!

I work in ASP.NET / VB.NET a lot and find ViewState an absolute nightmare. It's enabled by default on the majority of fields and causes a large quantity of encoded data at the start of every web page. The bigger a page gets in terms of controls on a page, the larger the ViewState data will become. Most people don't turn an eye to it, but it creates a large set of data which is usually irrelevant to the tasks being carried on the page. You must manually disable this option on all ASP controls if they're not being used. It's either that or have custom controls for everything.

在我使用的一些页面上，页面的一半是由ViewState组成的，这真的很遗憾，因为可能有更好的方法来做到这一点。

这只是我在语言/技术观点方面能想到的一个小例子。这可能会引起争议。

顺便说一下，你可能想在这个帖子上编辑投票，它可能会被一些人热得很;)

最好的代码通常不是你写的。作为程序员，我们希望通过编写一些很酷的方法来解决每个问题。任何时候，我们都能在解决问题的同时满足用户80%的需求，而无需引入更多代码进行维护和测试，我们已经提供了更多的价值。
