我仍然对以下的一些误解感到困扰——尽管我知道这些误解是正确的，但我仍然试图抓住它们不放:

All stakeholders will make decisions about software design objectively. Those that aren't embroiled in writing the code make all sorts of decisions based entirely on emotion that don't always make sense to us developers. Project budgets always make sense - I've seen companies that are quite happy to drop [just for example] $50,000 a month for years rather than pay $250,000 to have a project completed in 6 months. The government for one loses their annual budget if they don't spend it - so spend it they will, come hell or high water. It astounds me at how many project dollars are wasted on things like this. You should always use the right tools for the right job - sometimes this decision is not in your hands. Sometimes it comes down from on high that "thou shalt use X technology" for this project, leaving you thinking "WTF! Who came up with that ridiculous idea?"... the guy paying your paycheque, that's who, now get it done. Programming ideology comes first and foremost, everything else is secondary. In reality, deadlines and business objectives need to be met in order to get your paycheque. Sometimes you make the worst decisions because you just don't have time to do it the right way... just as sometimes that word is on the tip of your tongue but the minute it takes to recall it makes you choose a different and less ideal word. There isn't always time to do it right, sometimes there is only time to do it - however that may be. Hence oft' seen anti-patterns used by so called experienced developers who have to knock out a solution to a problem 10 minutes before the presentation deadline for the software being delivered to your best client tomorrow.

当我在TI-83上编程时，我认为你不能给变量赋值。因此(忽略这是C代码，不是TI-BASIC)而不是编写

c = c + 1;

我会写

d = c + 1;
c = d;

当我学习+=和++时，我惊呆了。

这种简单性几乎总能战胜复杂性。愚蠢的规则。

编辑:正如葛格所说，我把这个颠倒了。我的思绪一定是在回复中迷失了。如果使用得当，简单性几乎总是能让代码变得更好。

在很长一段时间里，我认为糟糕的编程是发生在边缘的事情。正确做事是标准。我现在没那么天真了。

在不浪费字节和CPU周期的情况下编写高效的程序是非常重要的。

但随着经验的积累，它与字节或CPU周期无关，它与你的思想流有关，连续的，不间断的，就像一首诗。

本质上，不要太努力。

当主流设计模式在计算机科学课上被引入时，我认为它们很棒。在此之前，我有8年的编程经验，对于如何创建好的抽象概念，我真的没有扎实的理解。

设计模式就像魔法一样;你可以做一些很棒的事情。后来我发现了函数式编程(通过Mozart/Oz、OCaml、后来的Scala、Haskell和Clojure)，然后我明白了许多模式只是样板，或者额外的复杂性，因为语言表达能力不够。

当然，几乎总是有某种模式，但它们在表达性语言中处于更高的层次。现在我一直在用Java进行一些专业编码，当我不得不使用访问者或命令模式等惯例而不是模式匹配和更高阶函数时，我真的感到很痛苦。
