I haven’t looked into this, but in step 3 can you call the editor’s undo function?

You mean like this?

What about simply shelling out to ripgrep?

These devices have been recommended in the past, and it looks like they can run OpenWRT

Bash and a dedicated user should work with very little effort. Basically, create a user on your VM (maybe called git), set up passwordless (and keyless) ssh for this user but force the command to be the git-shell. Next a simple bash script which iterates directories in this user’s home directory and runs git fetch —all. Set cron to run this script periodically (every hour?). To add a new repository, just ssh as your regular user and su to the git user, then clone the new repository into the home directory. To change the upstream, do the same but simply update the remote.

This could probably be packaged as a dockerfile pretty easily, if you don’t mind either needing to specify the port, or losing the machine’s port 22.

EDIT: I found this after posting, might be the easiest way to serve the repositories, in combination with the update script. There’s a bunch more info in the Git Book too, the next section covers setting up HTTP…

I would probably use ntfy.sh for this purpose. It doesn’t quite meet all your requirements, but you could use a random channel name and get some amount of security…

You can self host it, or use the hosted version. (I know it’s technically not chat, but it works on a series of messages, it just happens to call them notifications.)

Yes, I have. I should probsbly test them again though, as it’s been a while, and Immich at least has had many potentially significant changes.

LVM snapshots are virtually instant, and there is no merge operation, so deleting the snapshot is also virtually instant. The way it works is by creating a new space where the difference from the main volume are written, so each time the application writes to the main volume the old block will be copied to the snapshot first. This does mean that disk performance will be somewhat lower than without snapshots, however I’ve not really noticed any practical implications. (I believe LVM typically creates my snapshots on a different physical disk from where the main volume lives though.)

You can my backup script here.

I don’t bother stopping services during backup, each service is contained to a single LVM volume, so snapshotting is exactly the same as yanking the plug. I haven’t had any issues yet, either with actual power failures or data restores.

I would create separate nodes for each piece of metadata within the scene you are loading, you can use a Node2D (or Node3D) to store a position (such as a spawn point) and there is a Timer node which can hold the time for a level.

Alternatively, under the node inspector there is an option to “Add Metadata”, which might be more along the lines of what you are looking for. It can be read with the get_meta function.

I know it’s not ideal, but if you can afford it, you could rent a VPS in a cloud provider for a week or two, and do the download from Google Takeout on that, and then use sync or similar to copy the files to your own server.

For no 1, that shouldn’t be dind, the container would be controlling the host docker, wouldn’t it?

If so, keep in mind that this is the same as giving root SSH access to the host machine.

As far as security goes, anything that allows GitHub to cause your server to download (pull) and use a set of arbitrary of Docker images with arbitrary configuration is remote code execution. It doesn’t really matter what you to secure access to the machine, if someone compromises your GitHub account.

I would probably set up SSH with a key dedicated to GitHub, specifically for deploying. If SSH is configured to only allow keys for access, it’s not much of a security risk to open it up to the internet. I would then configure that key to only be able to run a single command, which I would make a very simple bash script which runs git fetch, and then git verify-commit origin/main (or whatever branch you deploy), befor checking out the latest commit on that branch.

You can sign commits fairly easily using SSH keys now, which combined with the above allows you to store your data on GitHub without having to trust them to have RCE on your host.

My recommendation would be to utilize LVM. Set up a PV on the new drive and create an LV filling the drive (wit an FS), then move all the data off of one drive onto this new drive, reformat the first old drive as a second PV in the volume group, and expand the size of the LV. Repeat the process for the second old drive. Then, instead of extending the LV, set the parity option on the LV to 1. You can add further disks, increasing the LV size or adding parity or mirroring in the future, as needed. This also gives you the advantage that you can (once you have some free space) create another LV that has different mirroring or parity requirements.

I use the first option, but with the addition of using an LVM snapshot to guarantee that the database (or anything else in the backup) isn’t changed while taking the backup.

Getting a domain name may not be enough, if you don’t have a static IP you’ll still need a DDNS service.

What do you get for the paid no-ip service? Is it just a nice subdomain? You can get a custom domain and use a CNAME record to point one or more subdomains to a free DDNS subdomain.

See my other reply here.

I followed the guide found here, however with a few modifications.

Notably, I did not encrypt the borg repository, and heavily modified the backup script.

#!/bin/bash -ue

# The udev rule is not terribly accurate and may trigger our service before
# the kernel has finished probing partitions. Sleep for a bit to ensure
# the kernel is done.
#
# This can be avoided by using a more precise udev rule, e.g. matching
# a specific hardware path and partition.
sleep 5

# Script configuration

# The backup partition is mounted there
MOUNTPOINT=/mnt/external

# This is the location of the Borg repository
TARGET=$MOUNTPOINT/backups/backups.borg

# This is the file that will later contain UUIDs of registered backup drives
DISKS=/etc/backups/backup.disk

        if grep --quiet --fixed-strings $uuid $DISKS; then
                break
        fi
        uuid=

if [ ! $uuid ]; then
        echo "No backup disk found, exiting"
        exit 0
fi

echo "Disk $uuid is a backup disk"
partition_path=/dev/disk/by-uuid/$uuid

function backup () {

Most of my services are stored on individual LVM volumes, all mounted under /mnt, so immich is completely self-contained under /mnt/photos/immich/. The last line of my script sends a notification to my phone using ntfy.

Here are a few more details of my setup:

Components:

• server
• clients (phone/laptop)
• domain name (we’ll call it custom.domain)
• home router
• dynamic DNS provider

The home router has WireGuard port forwarded to server, with no re-mapping (I’m using the default 51820). It’s also providing DHCP services to my home network, using the 192.168.1.0/24 network.

The server is running the dynamic DNS client (keeping the dynamic domain name updated to my public IP), and I have a CNAME record on the vpn.custom.domain pointing to the dynamic DNS name (which is an awful random string of characters). I also have server.custom.domain with an A record pointing to 10.30.0.1. All my DNS records are in public DNS (so no need to change the DNS settings on the computer or phone or use DNS overrides with WireGuard.)

Immich config:

version: "3.8"

services:
  immich-server:
    container_name: immich_server
    image: ghcr.io/immich-app/immich-server:release
    entrypoint: ["/bin/sh", "./start-server.sh"]
    volumes:
      - ${UPLOAD_LOCATION}:/usr/src/app/upload
    env_file:
      - .env
    ports:
      - target: 3001
        published: 2283
        host_ip: 10.30.0.1
    depends_on:
      - redis
      - database
    restart: always
    networks:
      - immich

WireGuard is configured using wg-quick (/etc/wireguard/wg0.conf):

[Interface]
Address = 10.30.0.1/16
PrivateKey = <server-private-key>
ListenPort = 51820

[Peer]
PublicKey = <phone-public-key>
AllowedIPs = 10.30.0.12/32

[Peer]
PublicKey = <laptop-public-key>
AllowedIPs = 10.30.0.11/32

Start WireGuard with systemctl enable --now wg-quick@wg0.

Phone WireGuard configuration (iOS):

[Interface]
Name = vpn.custom.domain

Private Key = <phone private key>
Public Key = <phone public key>

Addresses = 10.30.0.12/32
Listen port = <blank>
MTU = <blank>
DNS servers = <blank>

[Peer]
Public Key = <server public key>
Pre-shared key = <blank>
Endpoint = vpn.custom.domain:51820
Allowed IPs = 10.30.0.0/16
Persistent Keepalive = 25

[On Demand Activation]
Cellular = On
Wi-Fi = On
SSIDs = Any SSID

This connection is then left always enabled, and comes on whenever my phone has any kind of network connection.

My laptop (running Linux), is also using wg-quick (/etc/wireguard/wg0.conf):

[Interface]
Address = 10.30.0.14
PrivateKey = <laptop private key>

[Peer]
PublicKey = <server-public-key>
Endpoint = vpn.custom.domain:51820
AllowedIPs = 10.30.0.0/16

My wife’s window’s laptop is configured using the official WireGuard windows app, with similar settings.

No matter where we are (at home, on a WiFi hotspot, or using cellular data) we access Immich over the VPN: http://server.custom.comain:2283/.

Let me know if you have any further questions.

If you want to change the name of the directory without breaking your volumes (or running services, etc), you can specify the name of the project inside the compose file

It saves into the tiddlywiki HTML file. The default behaviour is to then trigger the browser to download the file. You can absolutely store it in a git repository.

TiddlyWiki might be a good option. Technically it’s a wiki, but it is a single HTML page with all functionality built in JavaScript, you could host it on GH pages, though you wouldn’t be able to use its save feature there (you would have to save to your local machine and the deploy a new version). It stores text in little (or large) cards which can be given a title, tags and other metadata, and it providesa full search system.
