  • I genuinely don’t understand why people here are taking it so hard that I wish the Immich devs were using semver.

    Because you didn’t say that; you said “Breaking changes in a point release? Not cool” and later “I’m basing this off the guidelines at semver.org.”

    I’m paraphrasing your comments from memory, to be clear, so apologies if I misquoted you.

    It certainly felt to me like you were assuming that this project was using semver and was not following it well, not that you wouldn’t want to use a project that receives this many breaking changes / that doesn’t follow semver. Those complaints both make a lot more sense to me - and I’ve seen many people say similar things about Immich in the past. In fact, it’s a big part of why I haven’t migrated from Photoprism to Immich myself - in this regard they’re complete opposites.


  • I don’t think there’s any room to argue that announcing a 1.x with a change the developers say is a breaking change, which is what Immich have done, fits within the semver.org guidelines.

    That wasn’t the argument.

    Following semver is optional. If a project doesn’t explicitly state it is following semver, it shouldn’t be assumed that it is. With regard to Immich in particular, a cursory review of their documentation makes it clear that they are not following semver. Literally, go to https://immich.app/ and read the text at the very top of the page:

    ⚠️ The project is under very active development. Expect bugs and changes.

    Go to the repo and you’ll see the README, which states at the very top:

    • ⚠️ The project is under very activedevelopment.
    • ⚠️ Expect bugs and breaking changes.

    If you can read that, see that they’re on major version 1 with a minor version over 100, and you still think they’re using semver, then that’s on you.

    The devs have stated they won’t be using semver until they consider Immich production ready, and that moving to a 1.x version from 0.x was a mistake made some time ago. If you want to think about it as though it is semver, consider the major version to still be 0. See https://github.com/immich-app/immich/discussions/5086#discussioncomment-7593227 for example.

    As this project is clearly not following semver, the semver guidelines aren’t applicable and haven’t been violated.

    I don’t think there’s any room to argue

    Even if semver were applicable, in this case, I would still disagree. The text from semver.org states:

    8. Major version X (X.y.z | X > 0) MUST be incremented if any backward incompatible changes are introduced to the public API.

    It doesn’t state that any backward incompatible changes, period, require a major version increase, only changes to the public API. I would personally argue that the deployment configuration is part of the public API, but not all project owners agree with me. Even if they do agree, they might say that this was not a documented deployment configuration and thus not part of the public API, and that it therefore doesn’t necessitate an increase to the major version, but as they knew that people were using that configuration, anyway, they included a note about a potentially breaking change as a courtesy to those users.



  • This is what I would try first. It looks like 1337 is the exposed port, per https://github.com/nightscout/cgm-remote-monitor/blob/master/Dockerfile

    x-logging:
      &default-logging
      options:
        max-size: '10m'
        max-file: '5'
      driver: json-file
    
    services:
      mongo:
        image: mongo:4.4
        volumes:
          - ${NS_MONGO_DATA_DIR:-./mongo-data}:/data/db:cached
        logging: *default-logging
    
      nightscout:
        image: nightscout/cgm-remote-monitor:latest
        container_name: nightscout
        restart: always
        depends_on:
          - mongo
        logging: *default-logging
        ports:
          - 1337:1337
        environment:
          ### Variables for the container
          NODE_ENV: production
          TZ: [removed]
    
          ### Overridden variables for Docker Compose setup
          # The `nightscout` service can use HTTP, because we use `nginx` to serve the HTTPS
          # and manage TLS certificates
          INSECURE_USE_HTTP: 'true'
    
          # For all other settings, please refer to the Environment section of the README
          ### Required variables
          # MONGO_CONNECTION - The connection string for your Mongo database.
          # Something like mongodb://sally:sallypass@ds099999.mongolab.com:99999/nightscout
          # The default connects to the `mongo` included in this docker-compose file.
          # If you change it, you probably also want to comment out the entire `mongo` service block
          # and `depends_on` block above.
          MONGO_CONNECTION: mongodb://mongo:27017/nightscout
    
          # API_SECRET - A secret passphrase that must be at least 12 characters long.
          API_SECRET: [removed]
    
          ### Features
          # ENABLE - Used to enable optional features, expects a space delimited list, such as: careportal rawbg iob
          # See https://github.com/nightscout/cgm-remote-monitor#plugins for details
          ENABLE: careportal rawbg iob
    
          # AUTH_DEFAULT_ROLES (readable) - possible values readable, denied, or any valid role name.
          # When readable, anyone can view Nightscout without a token. Setting it to denied will require
          # a token from every visit, using status-only will enable api-secret based login.
          AUTH_DEFAULT_ROLES: denied
    
          # For all other settings, please refer to the Environment section of the README
          # https://github.com/nightscout/cgm-remote-monitor#environment
    
    

  • To run it with Nginx instead of Traefik, you need to figure out what port Nightscout’s web server runs on, then expose that port, e.g.,

    services:
      nightscout:
        ports:
          - 3000:3000
    

    You can remove the labels as those are used by Traefik, as well as the Traefik service itself.

    Then just point Nginx to that port (e.g., 3000) on your local machine.

    —-

    Traefik has to know the port, too, but it will auto detect the port that a local Docker service is running on. It looks like your config is relying on that feature as I don’t see the label that explicitly specifies the port.






  • You can run a NAS with any Linux distro - your limiting factor is having enough drive storage. You might want to consider something that’s great at using virtual machines (e.g., Proxmox) if you don’t like Docker, but I have almost everything I want running in Docker and haven’t needed to spin up a single virtual machine.


  • Wow, there isn’t a single solution in here with the obvious answer?

    You’ll need a domain name. It doesn’t need to be paid - you can use DuckDNS. Note that whoever hosts your DNS needs to support dynamic DNS. I use Cloudflare for this for free (not their other services) even though I bought my domains from Namecheap.

    Then, you can either set up Let’s Encrypt on device and have it generate certs in a location Jellyfin knows about (not sure what this entails exactly, as I don’t use this approach) or you can do what I do:

    1. Set up a reverse proxy - I use Traefik but there are a few other solid options - and configure it to use Let’s Encrypt and your domain name.
    2. Your reverse proxy should have ports 443 and 80 exposed, but should upgrade http requests to https.
    3. Add Jellyfin as a service and route in your reverse proxy’s config.

    On your router, forward port 443 to the outbound secure port from your PI (which for simplicity’s sake should also be port 443). You likely also need to forward port 80 in order to verify Let’s Encrypt.

    If you want to use Jellyfin while on your network and your router doesn’t support NAT loopback requests, then you can use the server’s IP address and expose Jellyfin’s HTTP ports (e.g., 8080) - just make sure to not forward those ports from the router. You’ll have local unencrypted transfers if you do this, though.

    Make sure you have secure passwords in Jellyfin. Note that you are vulnerable to a Jellyfin or Traefik vulnerability if one is found, so make sure to keep your software updated.

    If you use Docker, I can share some config info with you on how to set this all up with Traefik, Jellyfin, and a dynamic dns services all up with docker-compose services.


  • Look up “LLM quantization.” The idea is that each parameter is a number; by default they use 16 bits of precision, but if you scale them into smaller sizes, you use less space and have less precision, but you still have the same parameters. There’s not much quality loss going from 16 bits to 8, but it gets more noticeable as you get lower and lower. (That said, there’s are ternary bit models being trained from scratch that use 1.58 bits per parameter and are allegedly just as good as fp16 models of the same parameter count.)

    If you’re using a 4-bit quantization, then you need about half that number in VRAM. Q4_K_M is better than Q4, but also a bit larger. Ollama generally defaults to Q4_K_M. If you can handle a higher quantization, Q6_K is generally best. If you can’t quite fit it, Q5_K_M is generally better than any other option, followed by Q5_K_S.

    For example, Llama3.3 70B, which has 70.6 billion parameters, has the following sizes for some of its quantizations:

    • q4_K_M (the default): 43 GB
    • fp16: 141 GB
    • q8: 75 GB
    • q6_K: 58 GB
    • q5_k_m: 50 GB
    • q4: 40 GB
    • q3_K_M: 34 GB
    • q2_K: 26 GB

    This is why I run a lot of Q4_K_M 70B models on two 3090s.

    Generally speaking, there’s not a perceptible quality drop going to Q6_K from 8 bit quantization (though I have heard this is less true with MoE models). Below Q6, there’s a bit of a drop between it and 5 and then 4, but the model’s still decent. Below 4-bit quantizations you can generally get better results from a smaller parameter model at a higher quantization.

    TheBloke on Huggingface has a lot of GGUF quantization repos, and most, if not all of them, have a blurb about the different quantization types and which are recommended. When Ollama.com doesn’t have a model I want, I’m generally able to find one there.


  • I recommend a used 3090, as that has 24 GB of VRAM and generally can be found for $800ish or less (at least when I last checked, in February). It’s much cheaper than a 4090 and while admittedly more expensive than the inexpensive 24GB Nvidia Tesla card (the P40?) it also has much better performance and CUDA support.

    I have dual 3090s so my performance won’t translate directly to what a single GPU would get, but it’s pretty easy to find stats on 3090 performance.
