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。

所有面向对象语言都有相同的面向对象概念。

Java接口=方法的接口。 Java接口是针对需要具有多重继承的特定于语言的解决方案。Ruby的mixin尝试解决同样的问题。 Javascript中提供的开箱即用的继承与Java实现继承的方式非常不同。

面向对象不一定比非面向对象好。

我认为OO总是更好的。然后我发现了其他技术,比如函数式编程,并意识到OO并不总是更好。

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.

html元素id和name属性是可以互换的。

事实证明,带有'name'属性的元素是相关的/被使用的。引用post等和'id'属性用于DOM引用。

当它们相等时,这个维n就是维(n+1)的实例。
