grub-reboot

# 方法1：最清楚（推荐）

grep -i -C 3 windows /boot/grub/grub.cfg # 或者 /boot/grub2/grub.cfg（Fedora系）

# 方法2：只看 menuentry 行

grep menuentry /boot/grub/grub.cfg | nl -v 0

# 方法3：快速只看含 Windows 的那几行

grep -i windows /boot/grub/grub.cfg

sudo grub-reboot "Windows Boot Manager (on /dev/nvme0n1p1)" && sudo reboot

webdav的ssl配置

1、webdav 服务器配置：

cert: ./tls_self/my-service.crt
key: ./tls_self/my-service.key

2、joplin PC客户端同步设置：
C:\Users\username\my-service.crt

3、小米15
只需要安装 ca.crt 即可

4、ios 18

通过“文件”程序安装证书
在“设置-通用-VPN“中安装描述文件（可能需要重启，才能安装成功）
在”关于本机“中，启用受信任的证书
经测试，超过10年有效期的证书，能安装

3、log

You are using a CUDA device ('NVIDIA GeForce RTX 3060 Laptop GPU') that has Tensor Cores.

To properly utilize them, you should set `torch.set_float32_matmul_precision('medium' | 'high')` which will trade-off precision for performance.

For more details, read https://pytorch.org/docs/stable/generated/torch.set_float32_matmul_precision.html#torch.set_float32_matmul_precision

使用python -m venv生成的虚拟环境，文件目录出错

windows中，

通过 python -m venv生成的虚拟环境，

在dos窗口中，通过activate.bat激活虚拟环境，

执行虚拟环境scripts目录中的python.exe，

实际执行的却是C:\Users\username\AppData\Local\Programs\Python\中的python

这可能是pytorch的DataLoader，当num_workers大于0时，出错的原因。

Change the location of the standard Python libraries. By default, the libraries are searched in prefix/lib/pythonversion and exec_prefix/lib/pythonversion, where prefix and exec_prefix are installation-dependent directories, both defaulting to /usr/local.

When PYTHONHOME is set to a single directory, its value replaces both prefix and exec_prefix. To specify different values for these, set PYTHONHOME to prefix:exec_prefix.

PYTHONPATH

Augment the default search path for module files. The format is the same as the shell’s PATH: one or more directory pathnames separated by os.pathsep (e.g. colons on Unix or semicolons on Windows). Non-existent directories are silently ignored.

In addition to normal directories, individual PYTHONPATH entries may refer to zipfiles containing pure Python modules (in either source or compiled form). Extension modules cannot be imported from zipfiles.

The default search path is installation dependent, but generally begins with prefix/lib/pythonversion (see PYTHONHOME above). It is always appended to PYTHONPATH.

An additional directory will be inserted in the search path in front of PYTHONPATH as described above under Interface options. The search path can be manipulated from within a Python program as the variable sys.path.
