Selfhosted

I've been into computers since around the mid 70s. First one was an Altair 8000. I have been selfhosting for years now, self taught and helped along of course by the selfhosting communities.

Not to speak bad of the dead, but I've really had it up to my back teeth with their bullshit. So I am in search of some self hosting brethren to chum around with. I figured I'd give Lemmy a try. It's kind of confusing, but hopefully I can wrap my 70 year old head around it.

I've seen a few selfhost forum around the fediverse but they all seem to have been abandoned with threads a year or more old, and no movement. So my question, is there a thriving selfhost/homelab type place that is active? Perhaps one of you good souls could point me in the right direction.

Is there any benefit to hosting your own Lemmy and mesh it with the other Lemmey's out there? What benefit would that be? From what I understand, hosting your own instance turns out to just be your own personal blog.

I mean, I understand the fediverse, and decentralization, I'm just having a bit of difficulty getting in with the right, active, group.

TIA

MAZANOKE is a simple image compressor and converter that runs entirely in your browser. No external uploads, works offline as a web app, and is powered by the "Browser Image Compression" library.

Github project page: https://github.com/civilblur/mazanoke

Features

• 🚀 Compress & Convert Images Instantly In Your Browser
  • Adjust image quality (0-100%).
  • Set a target file size.
  • Set max dimensions, to not exceed a certain width/height.
  • Convert between JPG, PNG, and WebP.
• 🌍 Installable Web App
  • Use as a Progressive Web App (PWA).
  • Dark and light mode.
  • Fully responsive for desktop, tablet, and mobile.
• 🔒 Privacy-Focused
  • Works offline.
  • All image processing happens locally.
  • No data is uploaded to external servers. Your files stay on your device.

Use case

This app is designed to compress smaller batches of images, aimed at casual users who need to compress and convert a few images at a time.

I created it primarily for friends and family who are less tech-savvy, to help them compress and convert images in a simple, safe, and private way.

Since the compression is handled in the browser, it won't cause any additional load on your server.

Additional notes

• I wanted it to be low-dependency, so it's built using pure HTML/CSS/JS.
• If you're wondering about the excessive amount of animations used, it's simply because I wanted to have fun working on this project. These types of animations are usually impractical for general purpose websites and are impractical to maintain.

Hi, I made this post a few days ago: https://lemmy.world/post/27391713 And I've been trying a lot of stuff and it doesn't work and it's driving me nuts. Now I tried again from the bottom and wrote down everything. You can see my notes here: https://docs.google.com/document/d/1vPplJhjZ13j1A2mEzHGS1B_sPSThE3LHxnGW82_F6Is/edit?usp=sharing Can anyone tell me why I keep banging my head against a wall here? Thanks :)

And I'm making everyone go to my gotosocial post because the server is running, so I'm going to use it!

I'm looking at quad port 2.5Gbe Intel PCIe cards. These cards seem to be mostly x4 physically (usually PCIe gen 3) whilst I have a PCIe Gen4 X1 slot, which is more the theoretical bandwidth that the card can support. The card needs at the most PCIE Gen 3 X2 == PCIE Gen 4 X1 in terms of bandwidth.

How do I fit the card into a PCIe x1 slot? Won't it lose performance if all the pins are not connected to the physical PCIe connector? Is there a PCIe x1 riser that the community likes that is somewhat affordable?

Thanks

Hey Self Hosted!

Got a shower thought I wanna bounce off youse guys. It's half-baked but itching to become real: DIY Sonos-like surround sound using Raspberry Pis (or maybe other SBCs if Pi's not cut out for it). Need your brains to kick things off!

The Vision:

Server Pi

• Acts as the brain. Takes 5.1 audio input from the TV (SPDIF? HDMI? Still figuring that out).

Client Pis

Wireless speakers running balenaSound or similar. Each handles a specific channel (front left, rear right, etc.). I do picture each of these being connected to a amplifier board. With some fancy wiring to give Raspberry pi voltages and power required for the amplifiers. (Something like this: https://a.co/d/fwkXuCm)

The Hurdles:

5.1 Audio Input

Can a Pi even handle 5.1 audio input? Do I need a fancy sound card/HAT? Or should I ditch the Pi for something beefier?

Channel Remapping Sorcery

Wiring all speakers the same (e.g., left channel only) but using Linux wizardry to assign which channel each speaker plays. Like, plug in a "rear right" speaker, tell the Pi "yo, you’re rear right now," and boom—it works. Possible? Or am I dreaming?

Why? Swapping speakers without rewiring = less headache. Plus, modularity.

First roadblock: Getting clean 5.1 into a Pi. Second headache: Software channel routing.

Anyone tackled something like this before? Am I reinventing a wheel that’s already on fire?

Edit: I think I may actually have found a solution even cheaper and I intended. Has anyone here ever heard of WiSa? Long story short it is a solution for Wireless Audio Cinemas. Mostly it is used in very expensive speakers, I'm talking like $5K USD for a whole system. However. I have found a much cheaper solution: https://a.co/d/fXkaMEX. This would be a good starter point for me because the server side already does everything that I want it to. The client side(speakers) are just about there... But I want to see better drivers and amplifiers. If I were to purchase this, I would use it as is initially, but eventually cannibalize the WiSa adapter, attach it to a strong amplifier, and mount the result in a better set of speakers.

When combined with today’s other vulnerabilities, CVE-2025-1974 means that anything on the Pod network has a good chance of taking over your Kubernetes cluster, with no credentials or administrative access required.

I am studying for my Network+ and my Sec+ hoping to shadow our Cyber Sec guy at work.

I want to set up a SIEM on my home network so I can be used to it's operations and how it works by the time I start messing with Pentesting stuff. Then I'm going to use it to try and track myself when I pentest myself.

I was looking into Graylog or Security Onion since they seem to have decent documentation (and I can find videos on how to set them up which is nice).

I was recommended building my own ELK stack and doing everything manually for maximum learning potential. Which I understand why this is a good idea, but I think I'd rather be as close to "baby's first SIEM" as possible or at least have a robust how-to guide.

What do you suggest?

I am quite worried about losing information and not being able to recover it from the backups, so I am trying to nail the best automated way to make sure the backups are good.

Restic comes with a check command, that according to the documentation here has this two "levels":

• Structural consistency and integrity, e.g. snapshots, trees and pack files (default)
• Integrity of the actual data that you backed up

In plain words, I understand this as: The data you uploaded to the repository is still that data.

Now my question is, do you think this is enough to trust the backups are right? I was thinking about restoring the backup in a temporary location and running diff on random files to check the files match the source, but I don't know if this is redundant now.

How do you make sure you can trust your backups?

Hi, I've tried running samba from docker compose on ubuntu server with this resource https://hub.docker.com/r/dockurr/samba I changed the default volume from "- ./samba:/storage" to "- /mnt/my_ext_hdd/my_dir/my_subdir" The container deploys fine, but I get permission error when trying to access the shared volume from windows? Anyone with some suggestionshoew to fix? Thanks

Saw that tab pop up sometime after the latest update. Loaded my shares to it and fired it up and its pretty sweet!

Was I mistaken in thinking that Music Assistant had the functionality of playing directly to the browser/app viewing the interface?

Hi guys!

The same way I hold some VMs for some apps I might not trust well enough to share with the rest of my OS/partition, I'd like to be able to do the same, but with LXC instead, possibly reducing overhead (and perhaps increasing ache in the head). I was wondering if the GUI Virt-manager can do this? It seems after installing libvirt-daemon-lxc, libvirtd, libvirt-client-qemu I'm able to connect to the LXC daemon in my system. However, I'm not sure how to follow a similar process as perhaps Proxmox, to build a, say, fully blown ubuntu LXC from a template. How should I do this?

Thanks!

I'm hosting a few services using docker. For something like an openstreetmap tileserver, I'd like it to remain on my SSD because high speed improves performance, and the directory is unlikely to grow and fill the drive.

For other services like NextCloud, speed isn't as important as storage size, so I might want it on a larger HDD raid.

I know it's trivial to move the volumes directory to wherever, but can I move some volumes to one directory and some volumes to another?

For years I've on and off looked for web archiving software that can capture most sites, including ones that are "complex" with lots of AJAX and require logins like Reddit. Which ones have worked best for you?

Ideally I want one that can be started up programatically or via command line, an opens a chromium instance (or any browser), and captures everything shown on the page. I could also open the instance myself and log into sites and install addons like UBlock Origin. (btw, archiveweb.page must be started manually).

I've been running my server without a firewall for quite some time now, I have a piped instance and snikket running on it. I've been meaning to get UFW on it but I've been too lazy to do so. Is it a necessary thing that I need to have or it's a huge security vulnerability? I can only SSH my server from only my local network and must use a VPN if I wanna SSH in outside so I'd say my server's pretty secure but not the furthest I could take it. Opinions please?

I'm still running a 6th-generation Intel CPU (i5-6600k) on my media server, with 64GB of RAM and a Quadro P1000 for the rare 1080p transcoding needs. Windows 10 is still my OS from when it was a gaming PC and I want to switch to Linux. I'm a casual user on my personal machine, as well as with OpenWRT on my network hardware.

Here are the few features I need:

• MergerFS with a RAID option for drive redundancy. I use multiple 12TB drives right now and have my media types separated between each. I'd like to have one pool that I can be flexible with space between each share.
• Docker for *arr/media downloaders/RSS feed reader/various FOSS tools and gizmos.
• I'd like to start working with Home Assistant. Installing with WSL hasn't worked for me, so switching to Linux seems like the best option for this.

Guides like Perfect Media Server say that Proxmox is better than a traditional distro like Debian/Ubuntu, but I'm concerned about performance on my 6600k. Will LXCs and/or a VM for Docker push my CPU to its limits? Or should I do standard Debian or even OpenMediaVault?

I'm comfortable learning Proxmox and its intricacies, especially if I can move my Windows 10 install into a VM as a failsafe while building a storage pool with new drives.

So I've got jellyfin all set up, but I'm having some issues with files downloading from qbittorrent and Knowing exactly how and when they get moved over, either the sonar or jellyfin repository, whichever is the final destination. This is important because my torrenting drive is separate from my media drive. I have noticed some shows and files staying on my torrenting drive while others go over to the media drive. And I'm and to figure out where the issue might be that's causing this, I think I need a refresher on exactly how and when these files are supposed to be moved over. Since I can't find any sort of documentation inside the apps.

Can anybody explain this to me like super simply? I just took an edible and it's starting to kick in, but I still want to figure this out. Thanks y'all!

I saw this article earlier:

Tesla 'going bankrupt' is endpoint of protests, says local organizer

In the spirit of right to repair, self-hosting, giving a second life to old devices, and limiting data collection by car companies:

• What are some considerations?
• Are there any projects worth keeping an eye on?

An example that came to mind was Valetudo, which is a cloud replacement for vacuum robots enabling local-only operation. Some robot vacuums are easy to install this on, and others require more invasive modifications.

What I've found so far:

• FreedomEV, a project that was presented at FOSSDEM 2019 but doesn't have recent activity
• TeslaMate, which is a popular and active selfhosted data logger for Teslas, but not necessarily a replacement for the software

Just taking a minute to share this podcast with y'all. I know it's already in the sidebar here, but thought Alex & Chris deserve a shout out for their great show.

They talk about the week's news and their own experiences hosting at home. Listening to them talk tech makes me more confident about my hosting.

Would this be useful if I wanted to setup Plex debrid on my jellyfin server? It has a couple of tmux sessions that randomly get killed. Would setting them up instead as pods work?
