Rich Hickey：Simple Made Easy（简单源于拆解）
Rich Hickey: "Simple Made Easy" from Strange Loop 2011 [video]
2011 — 2020，它一次次回到首页
黑点是上首页（≥ 50 分）的那次投稿，空心点是没冲上去的投稿，点越大分数越高。
导读
这是 Rich Hickey 在 Strange Loop 2011 的经典演讲，探讨软件开发中“简单”（simple）与“容易”（easy）的根本区别。他提出简单是一种选择，需要持续警惕和培养对“纠缠”（complecting）的敏感度，并强调通过分离独立概念来构建简单系统。演讲不限于 Clojure，适用于所有程序员。
为什么经久不衰：因为它用清晰有力的论证把“简单性”提升为一种需要主动捍卫的哲学，二十年来持续提醒开发者：容易不等于简单，选择简单需要持续警惕。

盛赞演讲带来启蒙，并提醒它不限于 Clojure。
对我来说，这是很久以来我看过的最好的演讲。它让我想起第一次读 PG（Paul Graham）文章时的感觉：有人把你自己的怀疑表达出来，同时走得更远更深，带你进入一个启蒙和清晰的状态。顺便说一句，没看过的人注意，这个演讲不是 Clojure 专属的。

For me this was the best talk I've seen in a long while. It reminded me of how I felt when I first read PG's essays, someone articulating your own suspicions whilst going further and deeper and bringing you to a place of enlightenment and clarity. BTW for those of you who haven't watched it, this talk is not Clojure specific.
批评 Hickey 贬低测试和类型检查，认为测试能反馈复杂性。
好演讲。但只有 Lisp 程序员才会把测试和类型检查叫做“护栏编程”。Hickey 说你应该推理你的编程，而不承认测试和类型检查是让你的推理成为可执行文档的方式。测试实际上会反馈到复杂性——如果某东西难以测试，那可能是由于复杂性，而你应该意识到并摆脱它。

A good talk. Leave it to a lisper though to call testing and type-checking "guardrail programming". Hickey says instead you should reason about your programming without acknowledging that testing and type-checking are ways to have executable documentation of your reasoning about your program. Testing does in fact feedback into complexity - if something is hard to test it may be due to complexity that you realize you should get rid of.
强调多次观看的价值，称其哲学深刻影响解决问题的方式。
通常我反对反复发帖，但这个视频我从头到尾看了 5 次以上，从未浪费时间。它优雅地表达了一种哲学，比其他任何东西都更塑造了我解决问题的方法。如果你从没看过，你是在亏待自己（也亏待那些依赖你高效解决问题能力的人）。

Normally I am opposed to chronic reposting but I have watched this video start to finish 5+ times and it has never been time wasted. It is an eloquent expression of a philosophy that has shaped how I approach problem-solving more than any other. If you've never watched it, you're doing yourself (and those who depend on your ability to efficiently and effectively solve problems) a disservice.
希望有面向管理层的浓缩版，并引用演讲关键结论。
值得再看，很高兴被重新发布并引起我注意。这次和去年坐在现场听一样震撼。我想看到或自己做一个面向非程序员、经理和高管的浓缩版论证。相信并践行简单的前提几乎需要空中支援和认同。他在结尾总结中有几句关键的话：“底线是简单是一种选择。如果你没有简单系统，那是你的错……它需要持续警惕……你必须开始培养对纠缠的感觉……你必须拥有纠缠雷达……你必须开始看到可能独立的事物之间的相互联系。”

This was worth watching again so I'm glad it was reposted and brought back to my attention. I was as struck by it this time as when I was sitting in the room listening to him last year. What I would like to see, or create if I have to, is a condensed version of this argument that is meant for the non-programmers, the managers, and the c-level employees of a business. The underlying premise of believing in and executing with simplicity is one that nearly requires air support, and buy-in. I think in his summary at the end there are a few key statements he makes: "The bottom line is that simplicity is a choice. It's your fault if you don't have a simple system.... it requires constant vigilance... You have to start developing sensibilities about entanglement... You have to have entanglement radar... You have to start seeing the interconnections between things that could be independent."
