园丁的困境：关于使用烟头浸泡液进行植物养护的全面毒理学与生态学分析报告 引言：解构一种民间偏方 在家庭园艺的实践中，流传着许多看似巧妙的民间偏方，它们往往源于资源匮乏时代的物尽其用思想，并通过代代相传延续至今。将泡过烟头的水用于浇花，以期达到杀虫的目的，便是其中一个典型例子。这种做法的逻辑看似简单直接：利用烟草的天然毒性来对付害虫，既能废物利用，又无需额外成本。然而，在现代科学的审视下，这一传统做法的背后，隐藏着远比其表面“益处”更为复… --- ## [Automatically update Searxng every 6 hours](https://eijil.com/t/automatically-update-searxng-every-6-hours/453)

味精，化学名称谷氨酸钠，在美国一直名声不佳。这既令人遗憾，也源于一些误传。好在，一大批崭新的烹饪书开始为它正名，重新唤醒我们对鲜味的感知。 比如最近一次家庭晚餐，我妻子伊丽莎白做了一道Sohla El-Waylly的“热辣拍黄瓜”。这道菜做法简单，无非是些我们家常备的黄瓜、辣椒脆、盐、糖和米醋，但伊丽莎白还悄悄加入了一点我们家厨房里不那么常见的秘密武器——味精！ 黄瓜沙拉的美味是意料之中的，但那一点点味精带来的额外鲜香，简直… --- ## [手机在偷偷的监听我们吗？](https://eijil.com/t/topic/543)

二战之前，美国在科学和工程领域还远远落在后面。然而，战争结束时，美国的科技实力已经全面超越英国，并在接下来的85年里执世界牛耳。 这一切之所以发生，是因为两位截然不同的人物分别担任了各自国家领导人的科学顾问。他们对于如何利用国家资源来发展先进武器系统，持有迥然不同的观点。战后，英国的早期领先优势昙花一现，而美国则为科技创新生态系统奠定了坚实基础，并借此引领世界 —— 直到如今。 英国模式：依托军方实验室 1940年，温斯顿·丘吉尔… --- ## [Find the fastest Ubuntu repository](https://eijil.com/t/find-the-fastest-ubuntu-repository/362)
