我正在对初级(也许是高级)软件工程师所犯的常见错误和错误假设进行一些研究。
你坚持时间最长、最终被纠正的假设是什么?
例如，我误解了整数的大小不是标准的，而是取决于语言和目标。说起来有点尴尬，但事实就是这样。
坦率地说;你有什么坚定的信念?你大概坚持了多长时间?它可以是关于一种算法、一种语言、一个编程概念、测试，或者任何关于编程、编程语言或计算机科学的东西。

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.

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。
我以为这将是一场过山车之旅，里面有飞驰的汽车、放荡的女人、私人飞机和大胆的冒险。等着瞧吧，直到我得到那个职业顾问....
当我第一次听说“鸭子打字”时，我以为它实际上是“管道打字”，类似于人们经常说的鸭子胶带。“Duck typing”听起来是错误的，而“pipe typing”则有一种奇怪的意义(拼凑的类型)。
这真的很尴尬，但当我开始学习如何编程时，没有什么能让我满意。我想写电子游戏。而不是这些书里让我写的那些琐碎的小程序。所以我决定跳过10章，忽略基础知识。
所以我基本上忽略了变量!
问题是我没有从惯例中识别关键字:
Car car = new Car(); //good
Car test = new Car(); //wrong must be lowercase car!
for (int i = 0; i < 10; i++) //good
for (int test = 0; test < 10; test++)//wrong must be i
我这样做了一年多，甚至用3000行字做了一个井字游戏! 当时我为自己的厉害而激动不已，直到我在互联网上找到了150行一字棋。然后意识到自己是个白痴，就重新开始。
每个人都想为一个问题写出最好的、最合适的代码……
