Hacker and Painter
黑客与画家

May 2003

(This essay is derived from a guest lecture at Harvard, which incorporated an earlier talk at Northeastern.)

When I finished grad school in computer science I went to art school to study painting. A lot of people seemed surprised that someone interested in computers would also be interested in painting. They seemed to think that hacking and painting were very different kinds of work– that hacking was cold, precise, and methodical, and that painting was the frenzied expression of some primal urge.
我读完计算机本科以后,去艺术学校学习绘画。许多人感到奇怪,喜欢计算机的人也会喜欢美术吗?他们大概认为编程序和画画是两种完全不同的工作,编程需要冷静,精密,和正确的方法,而画画是表达某种狂热的情感。

Both of these images are wrong. Hacking and painting have a lot in common. In fact, of all the different types of people I’ve known, hackers and painters are among the most alike.
这种印象是不对的,编程和画画有很多共同之处,实际上,在我认识的不同类型的人中间,画家和黑客是最相似的。

关于产品经理抬头

中午见一哥们,给我介绍另外一朋友,这哥们和我以前一起做过事,所以介绍的时候给我加了许多抬头,印成名片估计长度跟标哥有一拼的那种。

我连忙说,别别别,我其实只是个产品经理。你这是捧杀了。

见的事情多了,往往知道自己渺小。以前做讲座准备PPT的时候,作者栏都巨长无比,恨不得把我在学校得的桥牌冠军也写上。这些年才慢慢知道那些非专业级别的抬头根本不值一提。

呼吸、呼吸系统、搭建呼吸系统

人通过鼻孔呼吸氧气,氧气通过呼吸道进入肺部,在肺泡里与携带其他气体的血液交换,再通过血液循环供给到全身。

人为什么要呼吸?

人的呼吸与其他哺乳动物的呼吸有什么相同和不同?

哪种方式好?好在哪里?哪种方式不好?不好在哪里?

最经济最有效的方式是哪种?

多长时间间隔一次吸气比较合适?为什么?

为什么体积小的动物呼吸频率快,体积大的动物呼吸频率慢?

是体积影响呼吸频率吗?还是质量?或活动量?或交换比率?

单次最大必要呼吸次数=单位时间内需要的氧气量/单次最大量呼吸所含氧气量
