Archlinux Gnome 折腾技术
这次或许是最后一次，因为低配置的电脑已经运行不了了，既然不行，就没有使用 Linux UI 的必要了。很悲伤，很多东西走着走着都是作死。屠龙者终成恶龙！

Xorg cleanup requires manual intervention
2019-12-20 - Andreas Radke
In the process of Xorg cleanup the update requires manual intervention when you hit this message:
:: installing xorgproto (2019.2-2) breaks dependency 'inputproto' required by lib32-libxi
:: installing xorgproto (2019.2-2) breaks dependency 'dmxproto' required by libdmx
:: installing xorgproto (2019.2-2) breaks dependency 'xf86dgaproto' required by libxxf86dga
:: installing xorgproto (2019.2-2) breaks dependency 'xf86miscproto' required by libxxf86misc
when updating, use: pacman -Rdd libdmx libxxf86dga libxxf86misc && pacman -Syu to perform the upgrade.
css big event gray how to achieve技术
针对大事件灰色效果，CSS 的工作量可谓不小，可 CSS3 来了，只需一行代码搞定，其实就是这么简单，无需做什么准备。
.big-event-gray {
filter: progid:DXImageTransform.Microsoft.BasicImage(grayscale=1);
/* -webkit-filter: grayscale(100%); */
-moz-filter: grayscale(100%);
-ms-filter: grayscale(100%);
-o-filter: grayscale(100%);
/* filter: grayscale(100%); */
filter: gray;

bing 是一个伟大的搜索引擎技术
我遇到一个问题，使用最大的那个搜索引擎，搜不出任何相关的标题内容，点进去看了几个，完全没有找到相似点。
于是 bing 之。
结果，第一个就找到了答案，并且是标题完全相同。
大公司，转一个弯，几年都不一定做得到，只能是越陷越深。
我的问题是“/etc/rc.common: line 1: /data/clash: Permission denied”。
找到了两个有用的链接： https://github.com/juewuy/ShellClash/issues/246。https://github.com/juewuy/ShellClash/issues/226#issue-1373105062。
于是，感概下。
夜神模拟器安装系统根证书技术
安卓7.0之后，更加严格，这将导致一个结果，就是，你的手机，只是一个手机而已，而你几乎无法控制它。
其实作为一个开源的系统，真的不应该这样，因为，你是开源的，总会有办法。
其实，7.0 之后的安卓，用户证书变的没有意义。而目前的抓包工具，不论是 Charles 或者 是 Fiddler 几乎都是不能用的节奏。
下面讲一讲 Charles 抓取 https 数据接口。
Help -> SSL proxying -> Save Charles Root Certificate。下载完成后。点击 Install Charles Root Certificate On a Mobile Device or Remote Browser，在这个弹出窗能看到代理的 ip 和 port。
badblocks 命令要慎用了技术
