中国北方以种植小麦为主，南方以种植水稻为主。有一种理论，认为水稻需要稻农合作，解决灌溉和水灾，而小麦主要依靠雨水，不需要与其他人合作，所以北方人的个人主义倾向更强一些，南方人则是群体性倾向更强。

这个年纪，什么都想做，什么人都想认识，哪里都想去，好多书想读，好多电影想看，脑子里各种ideas
我不断告诉自己，你已经走上中国学生必经之路，那就再晚点吧，就几十天了，人生还有很多80天呢，什么都别想了。

Drug addiction
Using some recreational drugs can be rewarding, but the evidence is that addictive behaviours (and associated withdrawal phenomena) are determined by how the brain adapts in response to repeated drug administration rather than as a direct result of the fact that drugs may be intensely pleasurable. Conversely, although the reward properties of the drug are insufficient to explain addictive behaviours, it is simplistic, too, to consider addiction solely as behaviours aimed towards avoiding withdrawal symptoms. In addition to considering addiction in terms of the pursuit of pleasurable states (drug-induced euphoria) or the avoidance of withdrawal states (an array of physical and psychological symptoms which may actually be produced simply by a stimulus or environment that has become associated with previous withdrawal), we must also take into account what may be considered a markedly augmented state of motivation to taking the drug – referred to as craving. Important in this respect is the fact that a craving may be precipitated by a drug-related stimulus or environment long after the individual has recovered from the withdrawal symptoms. Other important phenomena that need to be explained are tolerance (a requirement for increased frequency and/or dose of the drug with repeated usage) and sensitization (in contrast to tolerance effects, some of the consequences of the drug may actually increase with repeated ingestion). Interestingly, neither tolerance nor sensitization are explicable in purely pharmacological terms because both phenomena also show certain features suggesting that they are conditioned responses. One view that has been put forward to account for the simultaneous occurrence of tolerance and sensitization is that while the pleasurable effects of the drug diminish with repeated administration (leading to tolerance), the drug and related environments and paraphernalia become, over time, more likely to capture attention and to precipitate the associated behaviours (sensitization). While the neurobiological basis of drug addiction is still not fully understood, there is increasing evidence that it involves mesolimbic dopamine systems and genetic susceptibilities, which may in turn affect the normal functioning of this pharmacological system.

Once upon a time, it was easy to mine Bitcoin. But Bitcoin took off, and it’s now absurdly hard to mine Bitcoin. You need farms of GPU mining just to get tiny amounts of bitcoin.
That’s artificial scarcity. Just when we need to cut emissions more, we are burning through our planet just to make the top 0.1% richer while people in Indonesia lose their homes to more frequent tropical disasters.

Because I have neither personally met nor spoken to 99.99% of all people I “know” on the Internet, my first impression about a person is formed on the basis of their spelling and grammar on their Twitter bio, tweet, Tumblr post, or article on Medium.

你可以去追，但不要丢失了自己。如果你发现了一个人可能并不怎么在意你，那你就要试着放弃，放开手，如何还能回来，那就是属于你的，如果就此消失，那就只能各自向前奔赴另外的属于自己的下一个山海。
我们终究会遇见双向奔赴的爱情，这种爱才值得一生托付。

Great love stories begin with such heady promise and end with such grief—but, at least in my case, also with memories of immense joy.

（1）蛋糕的制作有时间限制，软件也是。
你事先就知道，做蛋糕大概需要多久。如果你估计需要3个小时，那么稍微超出一点时间，问题不大。但如果你实际上拖了一周才做出蛋糕，蛋糕内部可能已经坏了。软件也是这样，如果实际耗费的时间大大超出原先的估计，这个软件十有八九是有问题的。
（2）蛋糕的体积很小，软件项目的规模也不应该很大。
小体积意味着你可以快速进行大量迭代，找出真正有效的方法。每次迭代都是一个实验，它帮你发现有价值的部分。小体积还可以很容易地进行试错。
（3）蛋糕有消费者，软件也必须有消费者。
如果你做出蛋糕，肯定有人愿意尝尝。用户会提供真正客观的数据，帮助发现蛋糕哪里做得比较好，哪里需要改进，这使得设计决策更容易。软件也必须有人愿意尝试，千万不要做出没有人愿意吃的蛋糕。
（4）做蛋糕很有趣，动手前你就知道会做出什么。
软件也应该这样，你很清楚做出来会是什么样，然后再迭代。每做一次蛋糕，就测试一个新想法。如果你感到这件事不再有趣了，很可能哪里出错了。
总之，你把软件想成是一块蛋糕，可以想通很多事情。

互联网开发已经变了，我们不再为互相链接和长期展示而创建内容，而是为了展示广告而创建内容。
内容的消费时间已经从几分钟下降到几秒钟，Facebook、Instagram 和 TikTok 这样的成瘾机器被认为是互联网的正确形式。

久而久之，我们被世俗的经验慢慢驯化着成为一个合格且体面的成年人，慢慢接受生活，也接受自己的人生。起初不知如何改变，后面干脆无奈接受。
我理解这部分无奈。在时代的年轮下，大多数人早已丢掉热血与方刚，还有的人也不愿再折腾，于是选择妥协，选择接受前辈们告诉我们的“这就是人生”这个经验。而后忍耐着。

新冠肺炎疫情刚暴发那年，美国《华盛顿邮报》曾让读者用一个词或一句话来总结2020年。收集来的句子充斥着“混乱”“迷失”“沮丧”等情绪。一位来自密歇根州的9岁孩子的回答被投票为最佳，他写的是：“感觉就像是过马路之前你明明小心地左顾右看了，结果却被一艘潜水艇撞倒。”
