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
