Running SMB share inside an nspawn container, this worked fine, but you're better off chrooting or using libvirt. It's just more straight forward using libvirt and alpine.

# host
sudo apt update
sudo apt install samba samba-common systemd-container

sudo debootstrap --arch amd64 jammy /var/lib/machines/mycontainer

sudo mount -o credentials=$HOME/.smbcredentials,uid=$(id -u),gid=$(id -g),iocharset=utf8 //smb-server/share /mnt/share

sudo machinectl mount mycontainer /mnt/share /mnt/share

# container
sudo systemd-nspawn -D /var/lib/machines/mycontainer --network=host
apt update
apt install samba

# Configure Samba's /etc/samba/smb.conf to expose directories as SMB shares.
# Sample config:
# [share]
#   path = /mnt/share
#   read only = no
#   guest ok = yes

sudo systemd-nspawn -D /var/lib/machines/mycontainer

smbclient //localhost/share -U your_username

Had to move a BTRFS pool spread accross multiple disks to a single one. Make sure to go through the docs for rebalancing.

// install btrfs tools if needed
apt install btrfs-progs
# or
dnf install btrfs-progs

// mount existing Btrfs filesystem
mount /dev/sda1 /mnt

// add new, larger disk
btrfs device add /dev/sdc1 /mnt

// rebalance data & metadata into single mode (onto the new drive)
btrfs balance start -dconvert=single -mconvert=single /mnt

// check balance progress
btrfs balance status /mnt

// verify
btrfs device status /mnt
btrfs filesystem show

Git module maintained by gogs doesn't support showing blob count for a tree item. This is generated from my patch file, used to have a similar patch for libgit2.

// Size returns the size of the entry.
func (e *TreeEntry) Size() int64 {
	e.sizeOnce.Do(func() {
		if e.IsTree() {
			stdout, err := NewCommand("ls-tree", "-l", e.id.String()).RunInDir(e.parent.repo.path)
			if err != nil {
				return
			}
			lines := len(strings.Split(strings.TrimSpace(string(stdout)), "\n"))
			e.size = int64(lines)
			return
		}

		stdout, err := NewCommand("cat-file", "-s", e.id.String()).RunInDir(e.parent.repo.path)
		if err != nil {
			return
		}
		e.size, _ = strconv.ParseInt(strings.TrimSpace(string(stdout)), 10, 64)

	})

	return e.size
}

Had to mount a BTRFS drive to windows recently, while winbtrfs does work for some basic operations, I wouldn't really trust it for funky things. In this case I had to consolidate multiple drives into a single one.

// windows
// get the drive ID
GET-CimInstance -query "SELECT * from Win32_DiskDrive"
// needs administrator—mount the drive
wsl --mount \\.\PHYSICALDRIVE1 --bare

// wsl | ubuntu
sudo apt install btrfs-progs
sudo mount /dev/sdd3 /mnt/$btrfs_mount
sudo btrfs device scan

// windows
wsl --unmount \\.\PHYSICALDRIVE1

The brotli-cli lacks an -r flag for now, can be circumvented using the output of find and piping it into xargs.

find . -name "*.{file-extension}" -print0 | xargs -0 brotli -Z

Rewrite the Content-Type header to serve raw files, as raw file delivery behaves inconsistently across different browsers.

@pgp_file path_regexp ^.*/public_pgp$
header @pgp_file Content-Type "text/plain; charset=utf-8"

@raw_file path_regexp ./raw/*
header @raw_file Content-Type "text/plain; charset=utf-8"

@ico_file path_regexp ^.*ico$
header @ico_file Content-Type "image/x-icon"

@jpg_file path_regexp .*jpe?g$
header @jpg_file Content-Type "image/jpeg"

@png_file path_regexp ^.*png$
header @png_file Content-Type "image/png"

@webp_file path_regexp ^.*webp$
header @webp_file Content-Type "image/webp"

Had some old pixel art I had to upscale.

ffmpeg -i input.webm -vf "scale=4800:2700:flags=neighbor" -c:v libvpx-vp9 -an output.webm
