How to use std::embed in C++?

The std::embed offers a standardized solution for C++ to include bytes of data into the target binary of the program.

For an example of bytes of data, we can demonstrate it in the segment of code:
byte data[] = { 0x01, 0x02, 0x03, ... };
auto result = process_my_data(data);

The problem here is that it's hard to maintain it when the data is large one. Many projects may use a standalone script to convert such a data array from a binary data file at the build stage.

The std::embed eliminates such a complexity for us, for example:
#include <embed>
std::span<byte> data = std::embed("my-data-file.bin");
auto result = process_my_data(data);

    The object is to shoot the objects at other objects with the same color. When you group them, they are eliminated. Your goal is to eliminate all of the objects before you run out of room. Fun game! teamviewer alternative free

How to copy a btrfs subvolume to another volume (partition/disk)?

The btrfs utility has two commands to write and read a subvolume to a general file, which can be a stdout/stdin too. They are ' send ' and ' receive '. Note that ' send ' and ' receive ' are designed for backup purposes. The received subvolume copy will be initially readonly. You have to normalize the copied subvolume with snapshot. Reference command sequence for copying subvolumes: 1. Create a readonly snapshot copy of the subvolume to be copied: btrfs subvolume snapshot /mnt/vol_0/sub /mnt/vol_0/sub.snapshot btrfs subvolume snapshot -r /mnt/vol_0/sub.snapshot /mnt/vol_0/sub.readonly 1. Copy the subvolume to another volume: btrfs subvolume send /mnt/vol_0/sub.readonly | btrfs receive /mnt/vol_1/ 2. Normalize the readonly subvolume copy with snapshot: btrfs subvolume snapshot /mnt/vol_1/sub.readonly /mnt/vol_1/sub 3. (Optional) Now the copied subvolume is available at /mnt/vol
