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。

这种编程软件需要扎实的高等数学基础。
在我开始编程之前,我总是被告知要成为一名优秀的程序员,你必须精通高级代数、几何、微积分、三角函数等。
十年后,我只做过一次八年级学生做不到的事。

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.
我一直认为,任何为任何语言编写任何代码的人都会使用编辑程序。
I was working with a client of mine who had me on mostly as support and to write some of the more complex things for him. Well one day he messed up a file, big time. He accidentally saved over three hours worth of his own work, and when I asked him why he didn't save more often he replied with, "because I wasn't done". Naturally, this was not an acceptable answer, and I poked and prodded a little further. I eventually came to find out that he he has never used any editing program, EVER! Not even notepad.exe! He had been using an online CPanel editor for files! It didn't even have a 'Find' function. He couldn't ever save until he was done because he was editing the live file on the site!
不用说,我很惊讶,他至今仍在使用CPanel编辑器……
以某种方式,一个运营大量相当高调/高流量网站的公司实际上知道他们在做什么。结果他们在很大程度上毫无头绪,而且非常幸运地处于他们所处的位置。所以我想寓意是,
可靠的软件工程和最佳实践=业务成功
还是……
大多数关键的软件系统==垃圾
我可以说服传统的过程程序员,为什么OOP经常提供更好的解决方案。
也就是说,一种描述世界的语言需要有描述复杂对象及其关系的能力。
争论通常包括关于抽象类的废话,我的回答是“不是所有的OOP程序员都刚从Uni毕业,还沉迷于抽象”。或者是经典的,“在面向对象编程中,没有什么是我用严格的过程式编程做不到的”,对此我通常会回答,“不是你能做到,而是如果你有一个更广泛的工具集,你是否会做到”。
我已经学会接受他们和我看世界的角度不同这一事实。
喂!,
我只是在设计和写代码。
没有需求收集、文档或支持。
