The Discipline of Observation — You Can Only Write What You Notice
自然 · 观察
一句话原则 + 名家原话
文字的素材是观察,不是想法。提请自己注意,才会真正看见;看不见,再好的文笔也无从落笔。
"Seeing is of course very much a matter of verbalization. Unless I call my attention to what passes before my eyes, I simply won't see it."
— Annie Dillard, Pilgrim at Tinker Creek (1974)
The onboarding flow has some friction.In ten session replays, six new users paused over 20 seconds on the email-verification step, and three abandoned there.
"A place is not a place until people have been born in it, have grown up in it, lived in it, known it, died in it — have both experienced and shaped it."
— Wallace Stegner, "The Sense of Place" (1992)
We have some scalability concerns with the database.The orders database tops out at 12k writes/sec; last Singles' Day it hit 18k at 21:00 and shed 4% of writes. That is the specific mountain we have to climb.
"I went to the woods because I wished to live deliberately, to front only the essential facts of life... Our life is frittered away by detail... Simplify, simplify."
— Henry David Thoreau, Walden (1854)
我们应该专注于真正重要的事,做减法。Less is more。我把每周的会从 14 个砍到 4 个。第一周很慌;第三周才看清:之前那 10 个会,多数只是在为彼此的存在辩护。
Our lives are too busy and full of distractions.I counted my recurring meetings: fourteen. I kept four. The other ten, I found, existed mostly to justify one another.
"I now suspect that just as a deer herd lives in mortal fear of its wolves, so does a mountain live in mortal fear of its deer."
— Aldo Leopold, "Thinking Like a Mountain", A Sand County Almanac (1949)
中译:我如今怀疑,正如鹿群活在对狼的恐惧里,一座山,也活在对它的鹿的恐惧里。
原理解读
Leopold 射杀了狼,以为帮了鹿;鹿群无狼而暴增,啃秃了整座山。「像一座山那样思考」就是把时间拉长、把边界放大,看见二阶、三阶后果。技术决策里这种盲区无处不在:优化了一个接口,把压力推给下游;砍了限流,眼前变快、季末崩盘。好的决策文档不止写「这个改动做什么」,更写「它会沿哪条链子传下去」。写作在这里是一种伦理:替读者看见他看不见的远处。
Removing the rate limiter will improve latency.Removing the limiter cuts latency today; by next quarter the unthrottled retries will erode the very capacity it freed — shooting the wolves to save the deer.
