Good Practice or Not - Adding Unique Identifier to Custom Options?
  • I think this is good idea. If the modules/options you are writing are for internal use, and not expected to be shared with the wider community, then this is great. I should incorporate this in my own config, but I dont know if this is common practice.

  • Proton just joined the AI clown car show
  • I might be naive, but given how often its being done I have to imagine that of all the project initiatives at Proton, adding LLMs is a relatively easy integration, when you compare it do developing a native application. Im sure theres been work at proton for a long time on those features, its just that the LLM team did this project quickly.

  • Making an iterator out of a function
  • Idk...kind of neat, but is the die rolling example any better than just doing 'while roll() != 6:'?

  • Thanks for sharing! The band poster is particularly very cool :)

    I wonder if someone would go so far as to put tags on each of their record albums to do the same thing (kind of odd not actually playing the vinyl, but it'd be easier to play an album!)

  • Looking for a cheap dopamine hit ;)
  • Not an answer: whats your setup for your cameras/security?

  • Looking for a cheap dopamine hit ;)
  • Ooh, Ive heard of these. Can you name some of the ways you use them? Do these effectively work as a cheap alternative to a physical switch or can they be used more creatively?

  • ergo ftw
  • Wow thats a crazy trackball! What brand/model is it?

  • Best way to host Nextcloud with Collabora Office?
  • I think containers get seen as overhead unfairly sometimes. Yes, its not running on bare metal, so theres a layer of abstraction, but I think in practice the performance is nearly identical. Plus, since AIO does things out of the box for you (like a redis cache for instance) it ends up being more performant than a standalone nextcloud instance that isnt configured properly.

    That is to say, I use AIO without issues.

  • What term to search for "oversized" keycaps?
  • Wasd keyboards sells individual keycaps. In their product page, they list the dimensions as XxY. https://www.wasdkeyboards.com/custom-text-cherry-mx-keycaps.html I dont know if thats standard practice, and on this site only that particular tall size. Not sure about in the general sense. Maybe you can search for 1x1.5 caps and see what you can find. Edit: nope, they dont even follow their own convention and just write 1xK where K is just rhe other dimension. Sad.

    You could always find a parametrized 3d model of a keycap in a particular style, and manually create the model and order to have it printed.

  • What is everyone's favorite coffee brand?
  • Its a online subscription service but they give you bags from roasters around the world. I see it advertised in youtube videos, and wasnt sure if people had used it to find new brands of coffee they liked.

  • Anyone drink tea? Have suggestions for a simple recipe?
  • Today, I was trying oolong. But I have black tea as well. No herbals or greens (I think those are the main families, right?)

  • What is everyone's favorite coffee brand?
  • Anyone ever done trade coffee? Is it worth it?

  • Anyone drink tea? Have suggestions for a simple recipe?

    I love coffee, but have a surplus of tea bags that I want to experiment with. Does anyone have suggestions for how to get started with tea? Or a simple recipe to use as a baseline? I'm only working with tea bags at this time, which appear to be 2g. I would also love to know how much agitation you are supposed to do with the tea bag itself.

    What's the ideal self hosted RSS setup?
  • Im using nextcloud news and the associated app. I like it because it lets me play podcasts in a player built into the android app. I havent found an up to date rss reader for freshrss that does the same (read you is beautiful, but doesnt have this feature.) And I have nextcloud already up so its easy to start with.

    Theres also many plugins for freshrss, including one for rss-bridge that turns urls into rss feeds. I use this for youtube subscriptions. You could also use rss bridge independently, which is what I use for nextcloud news.

  • NixOS module or docker container?
  • Yes. Oci-containers is similar to how you would setup a docker compose. Its not quite one to one. In particular, networks are odd, since you have to hand write a systemd service to create it? But thats only if you want isolated networks. You can find some examples on my github, I use it for most of my services. Heres an example of nocodb with backing postgres database. Its pretty simple: https://github.com/rutrum/dots/blob/master/hosts/modules/nocodb.nix let me know if you have questions in the future

    9.4GB Twitter(X) Data Leaked - Over 200 Million Records Exposed Online
  • Okay this looks big as far as data, but is there any information here that isnt (wasnt) already public? This looks like profile information. Isnt all this already available?

  • Python has too many package managers
  • I would love similar movement with regards to doc comment standards. My company uses numpy and its too verbose, and the style guide makes zero mention of type hints so we keep winging it. And with not many tools for enforcing the standards (like what type to actual write for a parameter) its an ongoing battle among the team.

  • In need of a paid Aternos server alternative (Exaroton excluded)
  • Logicservers is what I use. Its good. The multicraft UI kind of blows though, its also an old version. But they provide the .minecraft folder over ftp so you get full control. A lot of minecraft hosting dont give you that control and they artificially limit you, like capping player counts. Logicservers prices things based on hardware, not "features" like player counts or modding capabilities.

  • How do you manage your encryption keys?

    I'm in desparate need of setting up borgmatic for borg backup. I would like to encrypt my backups. (I suppose, an unencrypted backup is better than none in my case, so I should get it done today regardless.)

    How do I save those keys? Is there a directory structure I follow? Do you backup the keys as well? Are there keys that I need to write down by hand? Should I use a cloud service like bitwarden secrets manager? Could I host something?

    Im ignorant on this matter. The most I've done is add ssh keys to git forges and use ssh-copyid. But I've always been able to access what I need to without keeping those (I login to the web interface.) Can you share with me best practices or what you do to manage non-password secrets?

    NixOS module or docker container?

    If given the option, which route do you go? I have services running in both, and I'll often just do whats easier. I dont really notice a different in performance the configuration for containers is simple enough I don't mind it.

    I also wish there was a nix function that parsed a docker compose and used it for the oci-container config. Then I could use my existing compose files or the ones I find in docs online.

    Idea: NixOS configuration meant for hosting "for the common good" services, like tor relays, simplex relay, archive team warrior, etc.

    This idea is inspired by nixos-mailserver. It was so easy to spin up the mailserver after changing some DNS records and putting in some settings. I thought it might be a good idea to do the same for services that need public, decentralized infrastructure to support. Some ideas include

    • Tor relay, or exit node
    • Encrypted messaging nodes. It looks like SimpleX chat relies on SMP servers to relay communication
    • Crypto miners (I know, I know, but you understand how it fits the “public contribution” usecase)
    • Search engines like searxng (I currently use a public instance)
    • Libredirect services, like proxy clients for social media

    Maybe federated services, but those require more than just the software running on the public internet. Those require moderation and long term maintenance. Ideally, the services in this config would be ephemeral.

    Does this sound like a good idea? Would you spin one of these up on a $10 VPS? I understand that this is the NixOS community, not necessarily the privacy community, but I figured thered be overlap.

    What other services do you think would be applicable?

    Unable to run TabbyML with GPU on NixOS or Docker (solved on docker!)

    TabbyML is a self-hosted code assistant. I have been unsuccessful at running it using my Nvidia GPU. There's two ways I've tried to deploy this.

    As a docker container

    Following the docs, it states I run the following docker run command. Below is what I run, modified to use the correct port: docker run -it --gpus all \ -p 11029:8080 -v $HOME/.tabby:/data \ tabbyml/tabby serve --model StarCoder-1B --device cuda Then I get the following error: docker: Error response from daemon: could not select device driver "" with capabilities: [[gpu]]. So this would appear that I don't have the "nvidia-container-toolkit" installed on my machine. So I go ahead and enable this in nixos: hardware.nvidia-container-toolkit.enable = true; To validate that this works, I should be able to run nvidia-smi from within a container. I can run this from the host without issue: $ nvidia-smi Wed Jun 5 08:14:50 2024 +-----------------------------------------------------------------------------------------+ | NVIDIA-SMI 550.78 Driver Version: 550.78 CUDA Version: 12.4 | |-----------------------------------------+------------------------+----------------------+ ...and so on But if test this from a container, as the nvidia docs suggest as follows, I unable to access it from within the container. $ sudo docker run --rm --runtime=nvidia --gpus all ubuntu nvidia-smi docker: Error response from daemon: unknown or invalid runtime name: nvidia. Okay, so I go and read the instructions further. Install instructions state that after installation, I need to configure the runtime like so: $ sudo nvidia-ctk runtime configure --runtime=docker sudo: nvidia-ctk: command not found Ah nuts. That's a bug in nixos. I made a PR for this here: https://github.com/NixOS/nixpkgs/pull/317199 Still awaiting results from this. I don't know if this is a bug that will be backported to 24.05. Regardless, I wouldn't expect this ad-hoc configuration when I enable the nvidia-container-toolkit option in NixOS. Anyway, this option could still work but with some more time. If you have advice doing this let me know.

    FOUND Docker method solution

    So looking closer at people with the error message "no such runtime nvidia" I found this thread. It specifies that what nvidia-ctk is supposed to do is add a "runtime" that points to the nvidia-container-runtime executable. So I tried manually adding that my nixos configuration by using the virtualisation.docker.daemon.settings options. I was having trouble getting that working, because I needed to find the exact path to the nvidia-container-runtime executable. If you know Nix, you know that it isn't just in /usr/bin/.

    But that's still not a satisfying solution anyway...I shouldn't have to this. I went in deeper and looked at module for nvidia-container-toolkit. This module calls a script called cdi-generate.nix. It outputs the results of nvidia-ctk to a file called nvidia-container-toolkit.json.

    Let's go look for that file...can't find it. I do more searching...anyway, I found the solution.

    The nvidia-container-toolkit is a new option in NixOS 24.05. It explicitly states in the release notes that it is supposed to replace the now deprecated virtualisation.{docker, podman}.enableNvidia options. Well, when you go look at the module that defines docker.enableNvidia you see it there at the bottom! This file actually defines the nvidia runtime!

    And yes, it works. Using the now "deprecated" option is the one that actually works. I guess this is another bug to file to NixOS.

    This seems to work so far, but I don't know why the solution using a NixOS module doesn't work either.

    As a NixOS module

    Let's just do it the full NixOS module way (which is what I tried first). That should be easy. Let's enable the feature and set some options: services.tabby = { enable = true; port = 11029; acceleration = "cuda"; }; networking.firewall.allowedTCPPorts = [ 11029 ]; It appears to be working! VSCodium extension sees the server and prompts for a authentication token. I add the token. I type some code and set for a manual trigger...then tabby dies. Let''s look at the systemd logs. tabby[76786]: 📄 Version 0.11.1 tabby[76786]: 🚀 Listening at 0.0.0.0:11029 tabby[76786]: JWT secret is not set tabby[76786]: Tabby server will generate a one-time (non-persisted) JWT secret for the current process. tabby[76786]: Please set the TABBY_WEBSERVER_JWT_TOKEN_SECRET environment variable for production usage. systemd[1]: tabby.service: Main process exited, code=exited, status=1/FAILURE systemd[1]: tabby.service: Failed with result 'exit-code'. systemd[1]: tabby.service: Consumed 2.285s CPU time, received 121.0K IP traffic, sent 1.6M IP traffic That's it. It's not very descriptive about what happened. I've had success running it this way using the "cpu" option for acceleration (no GPU) but that's too slow to be useful.

    GPU specs

    I am running a Nvidia RTX 2060 and using the proprietary drivers version 550.

    Thanks for the read, if you have any input on what to do next let me know what I can try. Ideally, I'd like to have both options work, since I think the docker implementation may have the same problem as the NixOS module option.

    "No code" databases

    I've been seeing easy ways to store and view tabular data. I'm aware of tools like nocodb, baserow, and mathesar. I'm currently playtesting nocodb. But I wanted to start a discussion on what everyone uses for easily storing tabular data, and if anyone uses these tools.

    I've also tried nextcloud tables but it still is very early in development from what I can tell.

    Best service for filing taxes?

    I'm sure doing it manually is the safest, but perhaps there's a least poison for software/services for filing US taxes. What do you recommend? (or, atleast, what do you recommend steering clear of)

    What's the best strategy for changing to GrapheneOS?

    I have a google pixel, and I know I could install grapheneOS on it. But I'm very, very hesitant, since I depend so much on my phone.

    This isn't like distro hopping, where I feel more comfortable hot swapping ssds, or making partitions, or using my desktop while I tinker with my laptop. My phone has a SIM and the service I depend on can't be emulated off this phone.

    So what do you recommend I do? Should I move my SIM (my phone service, really) to a new phone while I tinker with this one? Can I just blow up the current OS and wing it? Or maybe theres another option that would allow me to bail back to stock android in case something goes wrong. What do you think?

    EDIT: how I use my phone: about everything I use is from fdroid, with the occassional app from aurora. I do use my banking app to cash checks, but I don't use whatsapp, google pay, which I know arent compatible. So as far as app compatibility I dont think it'll be a problem, Im mostly worried about my phone number not working. I dont know how SIMs work like I should, I just know Ive had the strangest issues in the past with it, so Im hesitant. Thanks for the replies so far.

    What guides, wikis, or megathreads are available for those new to archiving and storing data?

    I've recently aquired the hardware to build a home server/NAS. I'd love to know some community-guided advice on tools I should consider, and what best practices are?

    For instance, how does redundancy work? Whay about automated backups? What OS should be running on a NAS? What utilities can I use to monitor the safety of my data? Perhaps even a guide about how to safely share that data outside my home network for personal use, or even open for the internet, without compromising my network?

    Thanks for the discussion

    What's with all these hip filesystems and how are they different?

    You know, ZFS, ButterFS (btrfs...its actually "better" right?), and I'm sure more.

    I think I have ext4 on my home computer I installed ubuntu on 5 years ago. How does the choice of file system play a role? Is that old hat now? Surely something like ext4 has its place.

    I see a lot of talk around filesystems but Ive never found a great resource that distiguishes them at a level that assumes I dont know much. Can anyone give some insight on how file systems work and why these new filesystems, that appear to be highlights and selling points in most distros, are better than older ones?

    Edit: and since we are talking about filesystems, it might be nice to describe or mention how concepts like RAID or LUKS are related.

    New Nix Wiki: NixLang Wiki

    nixlang.wiki NixLang Wiki

    An unofficial, maintained wiki for NixOS

    Came across a new nix wiki attempt. The announcement post is made on discourse with high skepticism.

    But I really like it for two reasons:

    • For now, its incredibly informal and the barrier to entry is low. And because I can make edits directly in the web interface, it felt easy to contribute.
    • The creator mentions wanting this to be like the Arch wiki. In other words, contain information useful to nix users, but not necessarily nix specifically.

    I was able to contribute a new article about distrobox, a tool I discovered and made a post about here a month or so ago.

    Maybe we don't "need" another wiki, but the opportunity to contribute really made this one stand out to me. In case you all might want to contribute or learn something, I thought I would share.

    What should manage your xsession?

    I'm conflicted on what should handle my login manager, desktop environment, and window manager. What are the pros and cons of doing it from a nixos configurations versus a home manager configuration?

    Need to run something and nix just isn't cutting it? No worries, distrobox will save the day!

    I made a post a while ago asking what you do when NixOS isn't cutting it. You need a package that isn't available as a flatpak/appimage or already in nixpkgs. You don't want to build from source, because it's either too difficult or too time consuming. One suggestion was containerization or virtual machines, but those seemed too cumbersome. Well, distrobox is the tool that fixes it.

    Distrobox is a shell script that wraps over docker/podman to run a container of a distribution of your choice. But it does it behind a very high level API, and integrates the container environment seemlessly with your host environment. It is seriously as easy as this, if you need to install something with apt inside debian. $ distrobox create -n my_debian --image debian:latest $ distrobox enter my_debian And bang, your in a debian container and it won't even feel like it. It automatically integrates your shell environment and maps your root directory inside the container (or something like that.) You seriously wouldn't know unless you neofetch. Best part is that since everything is in the nix store, every program in your environment should work, for the most part, inside this container. I've not noticed problems yet.

    Tada! apt is available in this environment and you can install what you need. Then you can run it while inside the container. From the host machine, outside the container, you can run it directly too. Say you installed program X in debian: $ distrobox enter my_debian -- X And it will just run the command and send you back to the host machine.

    In the case of docker, you can type docker ps and it will show you your debian image my_debian listed.

    There's two more things I want to do to really polish this workflow. The first is to change my shell prompt so I know that I'm actually in debian without typing neofetch! Inside the box the variable CONTAINER_ID is set and the hostname is modified. I've adjusted my starship prompt to look like this when inside the box: distrobox:my_debian ~ $ And lastly, I really want to blur the lines. If I install X in debian, I want to just call it directly from the host as X, not invoke my debian instance with distrobox enter.

    When you type X and the program is missing, bash (and fish and zsh I'm sure) runs a hook that you can look at by typing $ declare -p -f command_not_found_handle By overriding this, you could first have it try the inside container if it can't find the application in the host container, like so. command_not_found_handle () { distrobox enter my_debian -- $@ } This is not a perfect solution, but I'm still experimenting with how to integrate this both seamlessly and also not accidentally run things inside debian and not realize it. If you have suggestions for how to improve handling calling commands from the outside environment, please share. Best case might just be adding aliases for programs explicitly. For example, `alias X=distrobox enter my_debian -- X.

    Anyway, distrobox is the solution! This is one more barrier removed that was preventing me from moving my main computer over to NixOS. I'm so happy to have found this and wanted to share.

    Thanks to dust I deleted a 70 gig file on my drive

    Dust is a rewrite of du (in rust obviously) that visualizes your directory tree and what percentage each file takes up. But it only prints as many files fit in your terminal height, so you see only the largest files. It's been a better experience that du, which isn't always easy to navigate to find big files (or atleast I'm not good at it.)

    Anyway, found a log file at .local/state/nvim/log that was 70gb. I deleted it. Hope it doesn't bite me. Been pushing around 95% of disk space for a while so this was a huge win 👍

    Do you use virtual credit cards?

    I came across privacy.com, a service that generates virtual credit cards, like aliases for your real credit card that can be paused or discarded at any moment.

    My own credit card company has this feature. But it requires a browser plugin that so obviously is there to track my spending habits, so I've not wanted to consider it. Privacy.com looks like a great alternative.

    But is it even worth it? It may be a hastle, but I can also cancel my actual credit card at any moment and they will send me a new number immediately and a card a few days later. From a privacy prospective, how much can a company use my credit card credentials to track me? Maybe a third-party virtual card provider even masks my own purchases so not even my credit card company knows? Not sure about that one.

    Please share if you use one, who its with, and if its worth it.

    Let NixOS or Home-Manager manage X, not both

    I've been spending a couple weeks unable to modify my system, because using my window manager was ungodly slow (like 1fps.) Luckily NixOS lets you pick a previous generation to load so I could make changes, build a new generation, and try again.

    It took me too long to find, but I realized I had both the x session managed by both nixos and home manager. Removing this fixed the problem. I assume this had 2 xsessions open and they were competing for resources or something. Be cautious! :)

    Coffee gamechanger for me: this big insulated coffee server.

    This is the 800ml server from Hario. I make 600g water / 30-35g coffee in it every morning.

    I drink my coffee slowly, and really like it hot. When I made a single 300g cup of coffee, I'd time my consumption wrong and it would be lukewarm before I finished. I didnt necessarily mind this, but now that I've been using this server I get hot coffee on demand, very conveniently.

    I downsized my regular mug for a teacup, so I always get just enough hot coffee to sip and enjoy before it loses too much temp. So now I drink a lot of small teacups worth instead of a regular mug. I recommend you try this style of serving coffee and see if its for you.

    Bonus: this has been so helpful when making for multiple people, since I dont always know when others wake up or come downstairs. Since its a huge insulated server I never worry about not being able to serve my roommates hot coffee.
