Using :has() as a CSS Parent Selector and much more
It’s been a long-standing dream of front-end developers to have a way to apply CSS to an element based on what’s happening inside that element.
今日学习 Linux:
iptables nat table 只有 conntrack 第一个包会进
如果一个包可能经过两次 iptables,可能需要用 conntrack zone 拆开:
Motivation: Proxmox 并且要出口 masquerade
(KVM <-- br0 --> veth <-- br1 --> host)

汤加火山喷发形成 90 米高海浪
2022-08-23 11:13 by 飞向火星
根据发表在《Ocean Engineering》期刊上的一项研究,1 月汤加火山爆发产生的最初海啸波高达 90 米,大约是 2011 年日本东北地方太平洋近海地震所产生海啸的 9 倍。这项研究是通过分析大气压力变化和海平面振荡的海洋观测数据记录,并结合经真实世界数据验证的计算机模拟进行的。 研究小组发现,汤加火山爆发产生的海啸是独一无二的,它不仅是火山爆发时排出的水形成的,而且是由多次环绕地球的巨大气压波形成的。这种“双重机制”造成了一场由两部分组成的海啸——最初由大气压力波产生海浪,在一个多小时后,由火山喷发的水位移产生第二波巨浪。

Wii U 模拟器 Cemu 开源
2022-08-25 13:45 by 我的世界
Wii U 模拟器项目 Cemu 宣布开源,源代码托管在 GitHub 上,采用 Mozilla Public License 2.0 许可证。开发者同时宣布了 Cemu 2.0,表示将提供 Linux 构建版本,但目前用户需要自己编译,未来计划提供 appimage 或 flatpak 打包格式。Cemu 项目还简化了版本号,从以前的三位数字简化为两位数,因此 Cemu 2.0 之后的下一个版本为 Cemu 2.1 和 2.2,而不是 Cemu 2.1.0。开发者承认选择开源的一个原因是开发停滞了,项目的另一个资深开发者退出,Cemu 的热度也降低,从高峰时逾百万人使用减少到每月下载量 25 万左右。开发者希望通过开源如果他退出的话会有人接手。
