基本配置
这个 HP T430 的配置为 Intel Celeron Processor N4000 （1.1 GHz up to 2.6 GHz）， 2G RAM + 16 G EMMC，千兆网卡，170 入手的（充电器 15，电源 25，快递 20），到手后决定先刷个 BIOS（原版的 BIOS 还是 2018 年的）。
为了方便安装（某种强迫症），我并不太希望在命令行中创建 pve 容器，因此希望直接在 web 创建，但是直接创建会提示报错 unable to detect OS distribution，搜索了半天并没有找到在 web 设置 OS type 为 unmanaged 的方法，因此只能手动修改 /usr/share/perl5/PVE/LXC/Setup.pm，让其将 openwrt 识别为 unmanaged

google on 和 google_scholar on 指开启 google 反代以及 google scholar 的反代
由于大多数 vps 的 ip 段已经被 google scholar 拉黑了, 因此要添加 upstream, 让 google scholar 使用 ipv6 连接来绕过谷歌的封锁。

s = "5D4A4759477D4C6836723437316E3B6E717A787E747F" xdctf='XDCTF{' for i inrange(len(xdctf)): print(int(s[i*2:i*2 + 2], 16) - ord(xdctf[i]))
使用下面的代码即可计算出该数字为 56451243
for i inrange(0, 10000): a2 = int('56451' + str(i)) if a2 % 5 == 3and a2 % 7 == 2and a2 % 13 == 4: print(a2)
知道了数字后即可解出flag
