WD-40配方背后的商业传奇 - 煎蛋

在加利福尼亚州的圣地亚哥，有一个比顶级私人会所更难进入的“神秘社群”。加入这个社群不需要名流身份，也 不需要巨额会费，它的入场券通常是一个高级行政职位，以及极其漫长的等待。这个社群唯一的特权，就是能亲 眼看一眼世界上最著名的多用途润滑剂——WD-40的秘密配方。

尽管有线杂志曾在10多年前尝试通过实验室检测来破解成分，并列出了一些 化学物质，但公司发言人表示，这就好比你虽然知道可口可乐里有碳酸水和糖，但仅仅把这些东西混在一起，绝 对做不出真正的可口可乐。

是无法做出还是无法大批量工业化生产？

Why Critical Thinking Is the Most Important Skill in Your Life - Psychology Today: The Latest

• Critical thinking keeps you alive by helping you avoid bad information that can harm your health.

When a rat encounters unfamiliar food, it often lets another rat eat first. If nothing happens, the observer will join in later. If the taster gets sick or dies, that food is banned forever. Rats remember these lessons for days, which makes poisoning entire colonies difficult. This behavior, known as bait shyness, has been documented for decades.

老鼠会对食物有「 毒害胆怯 」（Poison shyness) ，不愿吃未知的食物。人类似乎也应该对未知的信息也要有所警觉？

Touching grass - Protesilaos Stavrou: Master feed with all updates

We underestimate the latent toxicity of information and of the thoughts it can engender. We know that we should be careful about what we eat, drink, and breath, but we forget that what we think also contributes to our wellness or lack thereof. The information we are exposed to creates a certain climate that skews our perception accordingly. The question, then, is whether this is a viable environment for us.

The other day I was reading through my RSS feeds to catch up on the news. I noticed an article with a title along the lines of “I want to be allowed to hate on fatherhood” (me paraphrasing). The author was a man about to tell us how much suffering is involved in being a father. I thought to myself that this is yet another one of those common performative gimmicks of the attention economy: the influencer must be ever-more outrageous and controversial in order to outcompete other influencers in the race for clicks.

430k-year-old well-preserved wooden tools are the oldest ever found - Hacker News: Front Page

Tools predate homo sapiens (which emerged about 300 kYA) by millions of years. The first stone industry - Oldowan - is at least two million years old and might be as old as three million. They predate what we call “archaic humans” by a long time.

Even this evidence of woodworking is largely unremarkable. We’ve got phytolith [1] and microwear [2] studies showing unambiguous evidence of woodworking going back at least 1.5 million years. Wood tools just don’t survive very long, so this find is most notable for its preservation.
