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.

在学校里,你被教导编程是“读取输入,处理数据,写输出”。实际上,很少有处理步骤——大多数编码只是“读取输入,输出”。

一般来说,它要么是“从用户读取,写入数据库”,要么是“从数据库读取,显示在屏幕上”。这两种情况涵盖了大约95%的工作。

在开始开发之前,您可以完全理解问题。

学习一门全新的语言真的很难。

事实证明,在Linux下是否检查内存分配是否返回一个引用并不重要,因为它实际上会欺骗你,在未来的某个时候实际分配内存,或者如果它没有你需要的内存,就完全终止你的程序。

如果你看不懂我的代码,那你就是不懂这门语言。我有一些代码审查,我试图反击。

我又花了几年的时间才明白,有一个时间和地点可以让你的代码变得神奇,那就是在库中,而不是在应用程序中。该应用程序是为了清晰和可读性。Magic最好隐藏在扩展方法和框架后面。
