运行时性能很重要。总解决时间通常是最重要的。

自从学习python之后，我已经摆脱了对静态类型的依赖。

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……

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。

用汇编语言进行优化=重写。

When I first really understood assembly (coming from BASIC) it seemed that the only way to make code run faster was to rewrite it in assembly. Took quite a few years to realize that compilers can be very good at optimization and especially with CPUs with branch prediction etc they can probably do a better job than a human can do in a reasonable amount of time. Also that spending time on optimizing the algorithm is likely to give you a better win than spending time converting from a high to a low level language. Also that premature optimization is the root of all evil...

假设我把代码写得很好，尽可能没有错误，这就是我能做的最好的事情。事实证明，有时候经理们更喜欢那些努力成为他们最喜欢的人，而不是把工作做好的人。
