「地缘破碎」说（The fractured-land hypothesis）
Jesús Fernández-Villaverde，Mark Koyama，Youhong Lin & Tuan-Hwee Sng
https://www.zhihu.com/question/55635513/answer/1894684551336423771
摘要
国家的形成方式对经济发展有很大的影响。Diamond（1997）提出，中国之所以形成了大一统的国家，而欧洲却长期保持多中心的政治格局，一个关键原因是「地缘破碎」。为了验证这个观点，论文通过地形分析和农田分布，建立了一个包含详细地理信息的动态模型，试图定量评估地理分割对欧亚大陆国家形成的影响。
研究发现，地形确实是解释欧洲多中心主义和中国大一统的一个重要因素，但它并不是唯一的决定性因素。除了地形，农业生产力的差异，尤其是中国北方存在一个特别富饶的核心区域，也可能是导致这种差异的原因。论文进一步解释了这些结论如何与历史上的实际结果相吻合，并评估了这些结论的稳健性。此外，还论文探讨了这个模型是否可以用来预测非洲和美洲的国家形成模式。

互联网真是巨大草台
听说昨天 4chan 被黑了就去查了一下，是真的拿到了 root shell，而且居然不是靠社工
方法是上传了一份文件名是 .pdf 实际上是 postscript 的文件，然后服务器没有校验，用生成预览图的时候会执行的 ghostscript 的漏洞拿到了 shell... 🌚
我上次 CyberSci 2023 的时候解出来的一道防御题就是文件内容没有检查的漏洞，.pdf 后缀但是实际上是 php 脚本... 没想到居然大论坛的生产环境里也能看到这么基础的漏洞🤗
