-#lorem(10)
+- 桌面：2018年起主力使用Linux，Deepin #sym.arrow Arch #sym.arrow Gentoo #sym.arrow NixOS (2023-05-28)
+- 服务器（VPS）：差不多时间，OpenWRT #sym.arrow Ubuntu #sym.arrow Arch #sym.arrow Gentoo #sym.arrow NixOS
+- 科学计算（HPC）：2020年硕士入组开始接触，Gentoo + Ubuntu #sym.arrow NixOS (2023-09)

+  )
+- *复古*的包管理：手动修改Makefile指定编译器/参数/库路径。
+- *随意*的编程：无视标准、能用就行，C/C++不分，Fortran/MPI只有特定编译器能编译。
+- *闭源*的编译器：Intel OneAPI / NVIDIA HPC SDK。
+- *混乱*的用户权限：超算共用账户，小组随意`sudo make install`。
+]
+
+== 我们需要更多的可复现！
 
 
-== One column image

-//   image("image_1.jpg", height: 10.5cm),
-//   caption: [An image],

-//   #figure(
-//     image("image_1.jpg", width: 100%),
-//     caption: [An image],
-//   ) <image_label_2>
-// ]
+- 方便打补丁、魔改软件，无需研究具体软件的编译流程：
+  ```
+  xxx = prev.xxx.overrideAttrs (prev: patches = prev.patches or [] ++ [ ./my.patch ])
+  ```
+- 编译/运行环境可复现：
+  - “你遇到的问题，网上肯定也有人遇到过。Gentoo除外。”
+  - 再也不会忘记自己去年配置的服务是怎么配置的了。
+- 跨服务/跨机器共享配置
