Hi everyone,

As part of my dissertation for my Computer Science degree at Newcastle University, I investigated how to enhance the current state of 3D print failure detection. Current approaches such as Obico’s “Spaghetti Detective” utilise a vision based machine learning model, trained to only detect spaghetti related defects with a slow throughput on edge devices (<1fps on 2Gb Raspberry Pi 4b), making it not edge deployable, real-time or able to capture a wide plethora of defects. Whilst their model can be inferred locally, it’s expensive to run, using a lot of compute, typically inferred over their paid cloud service which introduces potential privacy concerns.

My research led to the creation of a new vision-based ML model, focusing on edge deployability so that it could be deployed for free on cheap, local hardware. I used a modified architecture of ShuffleNetv2 backbone encoding images for a Prototypical Network to ensure it can run in real-time with minimal hardware requirements (averaging 15FPS on the same 2Gb Raspberry Pi, a >40x improvement over Obico’s model). My benchmarks also indicate enhanced precision with an averaged 2x improvement in precision and recall over Spaghetti Detective.

My model is completely free to use, open-source, private, deployable anywhere and outperforms current approaches. To utilise it I have created PrintGuard, an easily installable PyPi Python package providing a web interface for monitoring multiple different printers, receiving real-time defect notifications on mobile and desktop through web push notifications, and the ability to link printers through services like Octoprint for optional automatic print pausing or cancellation, requiring <1Gb of RAM to operate. A simple setup process also guides you through how to setup the application for local or external access, utilising free technologies like Cloudflare Tunnels and Ngrok reverse proxies for secure remote access for long prints you may not be at home for.

Whilst feature rich, the package is currently in beta and any feedback would be greatly appreciated. Please use the below links to find out more. Let's keep failure detection open-source, local and accessible for all!

I maintain about a half-dozen simple landing pages for businesses of friends and family and I'd like to save them a bunch of money by just moving things to something in the house. At most, across all the landing pages, we're looking at no more than a few hundred visits a day, tops (and that'd be an outlier event).

In my research into this topic, I feel like the common wisdom is "don't do it." But assuming I'm using basic security best practices, what are the drawbacks/dangers of hosting websites from home?

Currently, as a personal project, I'm hosting one website on the ol' world wide web. I have just port 443 open, ssh access locked with sha-256 rsa-2048, and using cloudlfare's dns proxy for the site.

So far, as near as I can tell, I've had no issues. This has led me to think that I could go ahead an self-host several more websites. Is this a bad idea? A fine idea? Should I use Cloudlfare Tunnels? Something else?

I'm in that late beginner stage where I know enough to know I don't know what the hell I'm doing. Any help is appreciated.

edit for extra context: I'm currently working off an old Raspberry Pi 3, though if I go forward with adding websites, I'd probably shell out for one of the new Raspberry Pi 5 16gb. That is, unless someone has a better suggestion.

Hello everyone,

I just released Tinyauth v3.5.0 which finally includes LDAP support. This means that you can now use something like LLDAP (just discovered it and it is AMAZING) to centralize your user management instead of having to rely on environment variables or a users file. It may not seem like a significant update but I am letting you know about it because I have gotten a lot of requests for this specific feature in my previous posts and in GitHub issues.

You may or may not know what Tinyauth is but if you don't, it's a lightweight authentication middleware (like Authelia/Authentik/Keycloak) that allows you to easily login to your apps using simple username and password authentication, OAuth with Google, GitHub or any OAuth provider, TOTP and now...LDAP. It requires minimal configuration and can be deployed in less than 5 minutes. It supports all popular proxies like Traefik, Nginx and Caddy.

Check out the new release over on GitHub.

Have fun!

Edit(s): Fix some typos

For work, I often use digwebinterface.com, really handy! But I guess a lot of people think that way, so it is quite slow sometimes.

I've created an open source variant of digwebinterface with the goal to make it work as similar as possible that runs completely on your own hardware.

You can find the project here: https://github.com/Lars-/opensource-digwebinterface

Let me know what you think!

Hi r/selfhosted — I’ve built a simple python program ( https://github.com/OwlCaribou/swurApp ) to make sure episodes aren't grabbed until they've aired. This will help prevent things like malicious or fake files being downloaded before the episode is actually out.

It works by connecting to your Sonarr instance’s API and unmonitoring episodes that haven’t aired yet. Then, when the episodes air, swurApp will monitor them again and they should be picked up by Sonarr the next time it grabs episodes.

There’s a little bit of setup (you have to get Sonarr’s API key, and you have to tag the shows you don't want to track), but I’ve tried my best to detail the steps in the README file. Python is not my native language (I’m a Java dev by trade), so suggestions, feedback, and code contributions are welcome.

I know this issue has been plaguing some Sonarr users for a while, so I hope this makes a dent in solving the “why do I have Alien Romulus instead of xyz” problem.

(The stupid acronym stands for “Sonarr Wait Until Release” App[lication].)

Edit: This is a workaround for: https://github.com/Sonarr/Sonarr/issues/969 You CAN make Sonarr wait before grabbing a file, but it does not check if that file is actually within a valid timespan. It only checks for the age of the file itself. So last week someone seeded Alien Romulus as a bunch of TV series, and since it was seeded for several hours, Sonarr instances grabbed the file, even though the episodes hadn't aired.

Check out this thread for an example of why this issue isn't solved with the existing Sonarr settings: https://www.reddit.com/r/sonarr/comments/1lqxfuj/sonarr_grabbing_episodes_before_air_date/

Hey all,

I wanted to share something I’ve been working on: Webcap, a small self-hosted tool that watches websites for changes by taking full-page screenshots and tracking both visual and HTML diffs over time.

It’s useful for monitoring landing pages, docs, third-party dashboards, or really any site where you want to see when something shifts.

What makes it easy to run is Discode, another side project of mine that lets you install apps on your own server using a single curl command. Discode handles the setup, SSL, firewall, and reverse proxy configuration, so you can focus on the app itself.

You just need a public Linux server and a domain name pointed to it. After that, it's one command to get Webcap running.

If you're curious, here’s the Webcap site with more details and a live demo:
https://rubyup.dev/webcap

And if you’re building self-hosted tools in Rails yourself, I’d love feedback on Discode too:

Thanks for checking it out.

Setting up valutwarden with caddy & authelia

I got into self hosting recently and at the moment i'm trying to setup valutwarden with caddy and authelia.

I've set up the Caddyfile as such

auth.domain.tld { reverse_proxy authelia:9091 } # Vaultwarden vault.domain.tld { forward_auth authelia:9091 { uri /api/authz/forward-auth?authelia_url=https://auth.domain.tld/ copy_headers Remote-User Remote-Groups Remote-Name Remote-Email } reverse_proxy vaultwarden:8888 } 

Everything works using my tld, I get redirected to authelia, then back to valutwarden. However I'm unable to connect to my selfhosted vw via the bitwarden app.

I just found this project, which seems to do virtually everything Paperless-ngx does, with a few niceties: - Simpler UI (that's not necessarily a positive thing for everybody, but I definitely don't use all the features in Paperless) - Built-in Prometheus metrics - Supports multi-instance deployments for high availability

On the other hand: - It's not entirely clear to me without deploying it that it supports multiple users (which is a hard requirement for me) - While the documentation really goes in-depth in some aspects, it's not as exhaustive as Paperless - It clearly has way, way less users (at least for now...)

Has anyone given it a try? What has your experience been?

Hey

Im working a lot with copilot or chatgpt to try and set up the following:

I want my raspberry pi 5 to host Immich, Filebrowser and maybe other future things
I am using tailscale to connect my devices to reach the rbp

I want to set up filebrowser and immich and have decent looking urls without the port
For now I have been using MagicDNS to reach my rbp

Since immich can not handle base changes (so i cant use rbphostname/images) the LLMs directed me to set up a DNS on the rbp and add a nameserver in the tailscale settings

So i did a bunch of dnsmasq things and messed around with the nameservers but even at times the dns is reachable i can never get it to work

My first question is, is what I am doing possible?
My second is, is it a good option or would you suggest something else?
And lastly, if both are yes, could you give some tips to set it up or point me towards some documentation to help me do it?

Hi community,

Please forgive me if you think this is not the right sub to ask this question.

After months of going down the rabbit hole of trying to find my productivity suite, I realised that I need a distraction free chatbot like interface and a self hosted bot backend that integrates with other tools that I use.

Initially I was thinking of developing the UI as it gives me flexibility but it will be time consuming as I am primarily a backend developer do not have a lot of experience with UI. So I thought using Telegram or Discord might save me a lot of time and I can focus more on the stuff that matters to me more.

Anyone who has already taken this path, could you give me your two cents on why you chose one tool over other (Discord vs Telegram)? Also open to any other tools or advice that you might have!

Thanks!

Hi fellow hosters,

I'm running 3x Ubuntu hosts which each are running ONLY docker containers, 25 each or so.
Got into Cockpit and TuneD profile set to latency-performance.
Was wondering if there are any better options , distro-wise, maybe tailored to docker containers alone.
Or any distro that outperforms Ubuntu ...
Or any performance tweaks i should know of ...

Hi, I am looking for advice. I have a OMV NAS where I store all my files.

From time to time my friends ask me to share something with them, I mostly just copy the stuff to an USB stick and give it to them. I am looking for a solution that would allow me to just select files on my NAS, create share URL with expiration and send it to them, similarly to how OneDrive links work.

I went to through SeaFile and NextCloud, but both feel like an overkill. Do you know of any service that would work for me?

Another nice to have would be to have an option when others would be able to upload files to shaerd directory as well, but that is not needed at the moment.

Hey folks,

I'm doing some quiet research into how individuals and small teams are using AI without relying heavily on cloud services like OpenAI, Google, or Azure.

I’m especially interested in:

• Local LLM setups (Ollama, LM Studio, Jan, etc.)
• Hardware you’re using (NUC, Pi clusters, small servers?)
• Challenges you've hit with performance, integration, or privacy

Not trying to promote anything — just exploring current use cases and frustrations.

If you're running anything semi-local or hybrid, I'd love to hear how you're doing it, what works, and what doesn't.

Appreciate any input — especially the weird edge cases.
