Exec in as www-data and run ./occ groupfolders:scan folder_id -v (the -v to see what it’s doing)

lsof | grep /tank/nas shows me what is using my nas at any time!

➜ pihole sudo zfs load-key -L file:///path/to/.zfs.tank.key tank/encrypted/vms/arch-sandbox ➜ pihole sudo zfs change-key -o keylocation=file:///path/to/.zfs.tank.key -o keyformat=raw tank/encrypted/vms/arch-sandbox Need to load-key for each individual dataset, then change key location to be a file instead of the prompt

I’ve been using paperless-ngx to manage all my documents, but every once in a while I’ll get a .docx file to deal with…

Turns out Libreoffice has a headless mode a pdf converter built-in!

libreoffice --headless --convert-to pdf /path/to/file.docx --outdir /path/to/output/directory

Note that --outdir is in fact a directory, not the path to a file

ffmpeg -i input.mp4 -map 0 -c:v libx264 -vf format=yuv420p -c:a copy output.mp4

I was introduced to tiling window managers through i3, which I use heavily on one of my machines. I have switched to Pop_OS! at home though, which has a tiling window mode but the keybindings are not what I’m used to for i3. I wanted to at least navigate workspaces how I’m used to doing (cause I set workspace 3 for communication apps, 1 for my terminal, etc…)

Here’s how I set keybindings for:

• <Super> + <number> sends me to that numbered workspace
• <Shift> + <Super> + <number> moves the window I’m focused on to workspace number

I was getting (publickey denied) when trying to push to GH using ssh. When I tested the connection I saw that a bunch of keys in ``~/.ssh/ were being attempted

✗ ssh git@github.com -vv

...

debug1: Will attempt key: /home/nic/.ssh/id_rsa 
debug1: Will attempt key: /home/nic/.ssh/id_ecdsa 
debug1: Will attempt key: /home/nic/.ssh/id_ecdsa_sk 
debug1: Will attempt key: /home/nic/.ssh/id_ed25519 
debug1: Will attempt key: /home/nic/.ssh/id_ed25519_sk 
debug1: Will attempt key: /home/nic/.ssh/id_xmss 
debug1: Will attempt key: /home/nic/.ssh/id_dsa 

...

debug1: No more authentication methods to try.
git@github.com: Permission denied (publickey).

None of those were the key I setup with GH. So I added an entry into ~/.ssh/config:

Host
github.com
User git
Port 22
Hostname github.com
IdentityFile ~/.ssh/my_custom_github_key
TCPKeepAlive yes
IdentitiesOnly yes
