  • Here’s one I have saved in my shell aliases.

    nscript() {
        local name="${1:-nscript-$(printf '%s' $(echo "$RANDOM" | md5sum) | cut -c 1-10)}"
        echo -e "#!/usr/bin/env bash\n#set -Eeuxo pipefail\nset -e" > ./"$name".sh && chmod +x ./"$name".sh && hx ./"$name".sh
    }
    alias nsh='nscript'
    

    Admittedly much more complicated than necessary, but it’s pretty full featured. first line constructs a filename for the new script from a generated 10 character random hash and prepends “nscript” and a user provided name.

    The second line writes out the shebang and a few oft used bash flags, makes the file executable and opens in in my editor (Helix in my case).

    The third line is just a shortened alias for the function.




  • Even if you need something just once, just install it and then uninstall it, takes like 10 seconds.

    apt install foo && apt remove foo
    

    That’s essentially what nix-shell -p does. Not a special feature of nix, just nix’s way of doing the above.

    Actually using it though is pretty convenient; it disappears on its own when I exit the shell. I used it just the other day with nix-shell -p ventoy to install ventoy onto an ssd, I may not need that program again for years. Just used it with audible-cli to download my library and strip the DRM with ffmpeg. Probably won’t be needing that for a while either.

    The other thing to keep in mind is that since Nix is meant to be declarative, everything goes in a config file, which screams semi-permenant. Having to do that with ventoy and audible-cli would just be pretty inconvenient. That’s why it exists; due to how Nix is, you need a subcommand for temporary one-off operations.




  • Full disclosure: I’ve never used 1Password so can’t really comment on it compared with others, but I’m currently running a selfhosted Bitwarden re-implementation (vaultwarden) and am generally pretty happy with it. I’ve only ever used LastPass as a password manager before (aside from a seeding algo back in the day), and while I really don’t like their business practices or security history, their extension has or at least had a bit better consistency on Firefox than Bitwarden does, at least with regards to detecting username/password fields and detecting when a new credential is being created and asking it to be saved automatically. That being said, it’s something that I can live with considering it’s free software. As far as I’m aware, in terms of features all the big players in that space are pretty evenly matched, though I do remember some advanced feature that 1Password offered over others; maybe related to privilege access management in enterprise.








  • The way I have my monitoring set up is to poll the containers from behind the proxy layer. Ex. if I’m trying to poll Portainer for example:

    ---
    services:
        portainer:
        ...
    

    with the service name portainer

    from uptime-kuma within the same docker network it would look like this:

    Can confirm this is working correctly to monitor that the service is reachable. This doesn’t however ensure that you can reach it from your computer, because that depends on if your reverse proxy is configured correctly and isn’t down, but that’s what I wanted in my case.

    Edit: If you’re wanting to poll the http endpoint you would add it before like http://whatever_service:whatever_port


  • I believe the Pictrs is a hard dependency and Lemmy just won’t work without it, and there is no way to disable the caching

    I’ll have to double check this but I’m almost certain pictrs isn’t a hard dependency. Saw either the author or one of the contributors mention a few days ago that pictrs could be discarded by editing the config.hjson to remove the pictrs block. Was playing around with deploying a test instance a few days ago and found it to be true, at least prior to finalizing the server setup. I didn’t spin up the pictrs container at all, so I know that it will at least start and let me configure the server.

    The one thing I’m not sure of however is if any caching data is written to the container layer in lieu of being sent to pictrs, as I didn’t get that far (yet). I haven’t seen any mention that the backend even does local storage, so I’m assuming that no caching is taking place when pictrs is dot being used.

    Edit: Clarifications


  • Thanks for sharing! I’ll definitely be looking into adding this to my infra alerting stack. Should pair well with webhooks using ntfy for notifications. Currently just have bash scripts push to uptime-kuma for disk usage monitoring as a dead man trigger, but this should be better as a first-line method. Not to mention all the other functionalities it has baked in.

    Edit: Would also be great if there was an already compiled binary in each release so I can use bare-metal, but the container on ghcr.io is most-likely what I’ll be using anyway. Thanks for not only uploading to docker hub.



  • They most-likely used a Reddit Data Request. It’s kind of like Google Takeout if you’ve ever used that. If you’ve already deleted your reddit account it won’t work IIRC. I scrubbed my comments and posts with PowerDeleteSuite a day or two after I submitted the data request, but before I actually revived the data (took 20 days), but all of my comments and posts did show up in the data request. Don’t know if that points to reddit actually keeping that data in their database and just hiding it on the site or not, but either way, if it’s not visible on the site it becomes worthless to them unless they decide to provide that data to someone behind the scenes.
