Posting in case this helps anyone in the future. Not particularly difficult, I was just having this issue recently, and took some time today to work around it.

Lately, my Calibre-Web-Automated container will update eBook metadata, but will not update the book cover. I was never able to find an error, and using the CLI cover-enforce command didn't do anything either. I'm pretty sure that's all the GUI is doing, so not a surprise the CLI didn't work. Instead, it will insert a generic cover. For some lesser-known books, where it cannot find an appropriate cover, this procedure will also help.

First, ID the cover you want. If you have to manually scan the cover and get it into your container, you'll need to sort that out yourself. I was able to find decent enough covers on DDG image search. From there, drop into a shell in the CWA container, and run the following commands (Substitute variables below to meet your needs):

cd /calibre-library/${AUTHOR}/${BOOK_TITLE}  
curl "${IMAGE_URL}" > cover.jpg  
ebook-meta "${EBOOK_FILE}" --cover cover.jpg  

This assumes the image is a JPEG. Sub as necessary. Some that I found were WEBP files, and I wasn't sure they would work properly with ebook readers, so I just stuck with good old JPEG. Also, I figured the naming and placement of the cover file would scale fine for my whole library where needed. Adjust as you see fit.

ETA: Corrected a variable

I am looking at updating my email stack after a number of years and am wondering what to do for anti-spam. Is Spamassassin still the best option, or is there something better nowadays?

hi peeps.

Im early on my selfhosting journey and managed to setup some things as a test in docker. the main service im looking to run is ERPNext. after a while I got it up and running so now I want to back this up including all the customization I did in the app.

where to start with this? any intuitive guide?

I've been running nextcloud for my family and some projects about two years now and while it's allright when it's not breaking, I've had it break twice during upgrades and once outside of an upgrade. Getting back to running again during upgrades may require that I have two instances running one after the other - which is just too much to deal with for me, I'm anxious everytime a new update arrives, even though my system does backups and updates mostly automatic (yunohost).

(I run Nixos/Guix on my own laptop and get shivers anytime I have to deal with around in debian/android/anything-unlike-nixos-or-guix. And, yes, last I checked even Nixos struggles with nextcloud - which speaks volumes about it. I run yunohost on the server because it did DNS automagically)

So my question is, what could I change to that has:

• high reproducibility/easy maintenance/easy upgrades.
• file sync
• file sharing between users
• some kind of direct link file sharing

Nice to have:

• collaboration of some sort
• caldav (calendar and tasks)
• carddav (contacts)

Grateful for any and all inputs here. :)

Hello all,
I am attempting to self host piefed on a vps server running Debian 13 in docker with nginx proxy manager. I am at the step where I build it from source, and whenever I do it I get a ton of permission denied errors. I know the instructions said to chown 1000 the previous step, which I did but it still doesnt work. Thanks for the help.

Hi everyone. Hope you are well. BentoPDF recently hit 10k stars on Github in just under 3 months of launch and I am very grateful to the community! ❤️

BentoPDF's new version has been released. And I had implemented some of the requested feature here such as: Digital Signing of PDFs and Validation along with Email to PDF support and Deskewing of PDF. I have attached the release note link with the post. Moreover the OCR feature now performs on par with OCRMyPDF.

The reason I am making this post is gain feedback on the existing features of Bento, but most importantly Bento is going to have a Desktop version soon. Initially it will be launched for Mac users. Bento is inherently fast, but browsers and wasm have limitations, and this aims to solve it with the use of native libraries and leverage the CPU for faster processing and handling of large files efficiently.

I want to know what is the feature you use the most or is there any feature you'd like to be done that existing PDF softwares don't do well. I am happy for any feedback! Thank you (:

Trying to set Headscale up in a Debian VPS.

When I do

$ sudo headscale serve

I get the following error

failed to bind to TCP address: listen TCP 127.0.0.1:8080: bind: address already in use

Bit of a noob with crowdsec but I think its doing something that obstructs Headscale. If I stop crowdsec and do 'headscale serve' it seems to run without an issue.

I'm setting it up so that headscale listens on my domain using Caddy. This is the caddyfile:

sub.domain.com {
   reverse_proxy localhost:8080
   tls my.email@domain.com
}

Any ideas?

I'd like to set up a local coding assistant so that I can stop using Google to ask complex questions to for search results.

I really don't know what I'm doing or if there's anything that's available that respects privacy. I don't necessarily trust search results for this kind of query either.

I want to run it on my desktop, Ryzen 7 5800xt + Radeon RX 6950xt + 32gb of RAM. I don't need or expect data center performance out of this thing. I'm also a strict Sublime user so I'd like to avoid VS Code suggestions as much as possible.

My coding laptop is an oooooold MacBook Air so I'd like something that can be ran on my desktop and used from my laptop if possible. No remote access needed, just to use from the same home network.

Something like LM Studio and Qwen sounds like it's what I'm looking for, but since I'm unfamiliar with what exists I figured I would ask for Lemmy's opinion.

Is LM Studio + Qwen a good combo for my needs? Are there alternatives?

I'm on Lemmy Connect and can't see comments from other instances when I'm logged in, but to whomever melted down from this question your relief is in my very first sentence:

to ask complex questions to for search results.

My partner and I have accumulated a lot of memes and a lot of family photos over the years. I would like to host these so they are accessible via various devices. I'm doing the memes first and once I figure out the software better I'll move on to vacation photos. I had no problem getting Immich and Photoprism up and running. Both are very impressive programs, but both also are missing the ability to search/filter/sort by star rating. A lot of my memes and vacation photos are rated in their metadata as I never delete anything, I just rate the worthwhile ones higher so I can filter the junk out if we're showing someone the album. My visitors don't need to see all 10 distant dolphin pictures, just the good one where it's jumping out of the water. :D

Immich sees and can edit star ratings, though there is no search/filter/sort functionality and Photoprism doesn't seem to work with star ratings at all and uses the star the way Immich and Google photos use the heart.

My question is this:

Can anyone recommend a hosted alternative that implements star ratings completely and has an app or built in web server making it usable on desktop Linux, iOS, and Google-free GrapheneOS? It looks like Immich is slowly moving this direction and I can already see that this will be the best long term solution, at least for the family photos, but I want to set up something in the short term, especially since I have no idea what their feature timelines look like or how accurate they are.

I have a Netbird account I have tested and used to remotely access my network, and I plan to keep that account restricted to just me. Netbird has a free tier that's limited to 5 users/accounts and 100 peers (devices). I recently set up a Minecraft server on my Proxmox so I can play with a group of friends, but I obviously need more than just 4 accounts. Has anyone ever made a second account to share with multiple people? If you did, did you have MFA also turned on?

Hello, I recently switched from nextcloud news reader to freshrss and I was wondering wich is a good iOS client reader to match up?
I installed NNW but since I came from Nextnews which was great (but works only with nextcloud) I feel a bit uncomfortable... of course, that may be just a matter of time...
Thanks in advance !

It's the first idea I had when it came to making sure login on my server is secure. Instead of having a small password that relies on my fallinble memory and may be also guessed in a not-completely-rodiculous amount of time.

Meanwhile a fairly small file, something like a 512 byte "user.key", to be uploaded along with your username, or even just having your username built-in, seems much safer.

I wanted to do some math but I could only find limited calculators for doing calculations with such big numbers so have the amount of possible combinations the file may have:

What am I missing? I assume I'm missing something, because the idea of something like this going over a lot of smart programmers and developers' heads does not sound right

With the official app no longer updated (i don't trust the forks), i'm looking for alternatives for 2 way sync between my Android phone and my Linux server. I've tried nextcloud a long time ago and the experience was very bad. Are there any new tools that i can use?

I've been running Immich for about 6 months now, and it's smooth and stable.

I've synced my camera roll to it and loving it.
Next step is to move the ~150gb of media on Google-Photos over.
How do I best do that?

I also have some other issues I'd like to address before or after the migration:

1. I have a bunch of crap mixed into my Google photos, old WhatsApp images from meme groups I used to be in etc.
2. Thousands of photos of Ex girlfriends mixed in (not exactly sure what to do about these)

Is there a way to siff through these efficiently and keep what I want? I have ~20k photos some dating back to 2006 so it feels like a mountain to climb.

Reddit's API is effectively dead for archival. Third-party apps are gone. Reddit has threatened to cut off access to the Pushshift dataset multiple times. But 3.28TB of Reddit history exists as a torrent right now, and I built a tool to turn it into something you can browse on your own hardware.

The key point: This doesn't touch Reddit's servers. Ever. Download the Pushshift dataset, run my tool locally, get a fully browsable archive. Works on an air-gapped machine. Works on a Raspberry Pi serving your LAN. Works on a USB drive you hand to someone.

What it does: Takes compressed data dumps from Reddit (.zst), Voat (SQL), and Ruqqus (.7z) and generates static HTML. No JavaScript, no external requests, no tracking. Open index.html and browse. Want search? Run the optional Docker stack with PostgreSQL – still entirely on your machine.

API & AI Integration: Full REST API with 30+ endpoints – posts, comments, users, subreddits, full-text search, aggregations. Also ships with an MCP server (29 tools) so you can query your archive directly from AI tools.

Self-hosting options:

• USB drive / local folder (just open the HTML files)
• Home server on your LAN
• Tor hidden service (2 commands, no port forwarding needed)
• VPS with HTTPS
• GitHub Pages for small archives

Why this matters: Once you have the data, you own it. No API keys, no rate limits, no ToS changes can take it away.

Scale: Tens of millions of posts per instance. PostgreSQL backend keeps memory constant regardless of dataset size. For the full 2.38B post dataset, run multiple instances by topic.

How I built it: Python, PostgreSQL, Jinja2 templates, Docker. Used Claude Code throughout as an experiment in AI-assisted development. Learned that the workflow is "trust but verify" – it accelerates the boring parts but you still own the architecture.

Anyone using Revolt as a Discord alternative? What has your experience with it been? Do the voice chats work reliably? What about screen sharing? Is it easy to use? What hardware do you host it on? What about moving people over from Discord to Revolt?

I'm considering buying some.more solid self hosting hardware at some point and considering hosting a Revolt server for friends and a community that we're moderating.

Other software recomendations are also welcome, but keep in mind that voice chats and screen sharing are features that we very often use, so something that's primarily text-based like matrix won't work.

I'd also like to hear your thoughts on converting people to non-mainstream software. I'd expect it to not work so smoothly, since discord is such a go-to platform for so many people and most of them follow multiple communities on there. The convenience aspect is a big thing.

Please share whatever thoughts you have on this topic.

following up on my previous post:

it turns out that, like anything else weird in infrastructure, it was DNS

I registered mydomain.com as my primary router’s domain, re-ran the experiment with a fresh 128 char subdomain, and I received zero scans on the new domain.

Now my question is, who’s making that one query that leaks my domain name? Is it Apache on startup?

One solution is to resolve all my subdomains on /etc/hosts so it never has to leave the box, but I’m curious what a more experienced net admin would suggest.

Hi!

Maybe someone can help me with a problem I’m having, vaguely related to self hosting.

I want to use a domain with let’s encrypt certificates locally. I realise the only way to do this is a (automated) DNS-01 challenge if I don’t want to expose anything to the outside.

Those DNS challenges require my name server to have some kind of API to automate the process. My registrar/name server doesn’t have a API unfortunately.

I want to use the opportunity to switch my registrar and name server in one go, but I’m pretty picky…

My wish list is:

• MFA for general account administration
• scoped tokens or account for API access (don’t need or want to manage everything by API)
• can handle .at domains
• not cloudflare
• registrar and name server should be one entity if possible
• european if possible
• supported by ngnix proxy manager if possible

Backup plan would be picking a registrar which supports DNSSEC for .at domains and use desec.io I guess.

But maybe the hive mind has a good recommendation for me? :)

Thank you in advance for reading! I’m aware I’m just a bit extra, but i want to be able to just ignore the whole name server and domain topic for the next ten years again if I can.

Cheers!
