我曾经认为应用程序的大部分工作实际上是编程。我相信这在某些情况下是正确的，但根据我的经验，我花了更多的时间来研究、记录、讨论和分析，而不是实际编码。(我从事的是操作基于激光的传感器的软件，确定如何最好地控制硬件比编写代码更具挑战性。)

我也曾经认为，程序员可以回头问旁边的人问题的开放环境是程序员团队敲定解决方案的最佳环境。事实证明，不管有没有团队，一个黑暗孤独的房间效率更高。

当我毕业时，我认为专业编程就像在大学编程一样，这意味着我将得到输入和预期输出，并被要求填写进行转换的黑框。在现实中，我必须弄清楚输入，输出和黑盒。

我过去并不认为市场和销售人员是人类的祸害，太天真了。

I thought I'd be coding for 8 hours straight. Realistically, I get 4 hours a day of coding, 1 hour for lunch, 1 for coffee breaks, and 2 for screwing around / chit chatting/ stack over and under flowing. Prior to working, I thought that all clients would be idiots and don't know two craps about computers. Boy was I wrong on that one. Sometimes, we get projects by people who can do it better than we can, they just don't have the time to do it. I thought cubicles were bad, Right now I love them :D I actually moved from a door-ed office to a cubicle. I like the openness. All programmers are not athletic. I thought that I was the only one that goes to the gym. Where I work, at least 10 of us go to the gym every day at 5 am. I thought there would be no women programmers. A couple of our leads are ladies.

当然，您可以查看FindBugs和PMD，但这些是我最喜欢的陷阱和技巧(所有Java):

字段没有被覆盖，而是被遮蔽。

没有显式的super。超级访问。

未定义构造函数的类具有隐式零参数构造函数。今年我犯了一个与此相关的实际错误。

要获得对内部类的父类的引用，可以使用“Outer”语法。这“消除方法调用或同步的歧义”。

在c++术语中，类是“它们自己的朋友”，该类的任何实例的私有方法和字段都可以从同一类的任何方法引用，甚至是静态方法。这将使我早期的一些clone()和copy构造函数简单得多。

在扩展类的静态上下文中可以访问受保护的方法和字段，但前提是该类在同一个包中。我很高兴flex.messaging.io.amf不是一个密封的包。

销售人员实际地管理顾客的期望。(接受过承诺不足和超额交付的培训)

软件需求通常来自市场调查。

没有bug的软件是可能的。

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.
