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.

我最大的先入之见是,我将被允许以我想要的方式编程。当然,后来我离开了大学,进入了一家拥有荒谬框架、规则和程序的公司,这不仅意味着我不能以自己想要的方式编程,而且意味着我编程得很糟糕。

我一直认为,要成为一名优秀的程序员,必须了解系统的所有内部工作原理。我很羞愧,因为在开始编码之前,我不知道关于这门语言的一切,比如它的库、模式、代码片段。 我不再那么天真了。

我记得我10岁的时候,有人让我相信,将来会有一种计算机能够在3秒内运行一个无限循环。

通过实现客户想要的东西来满足客户——不幸的是,这意味着客户知道他想要什么。

以为我是唯一一个会写代码的人……然后当我需要这个例程时,我不记得我做了什么,只是复制/粘贴我自己的代码。

我知道每个人都这么做。
