What's your weirdest or most unique self-hosted use case and solution? (lemmy.today)

I'm self hosting on an old laptop, and I'm a convert for life. Self-hosting is amazing. Looking for other people's weirdest examples of what they're doing as inspiration.

My example, I recently set up a grammar script, where I have a couple 8b LLMs and an html landing page. I upload a doc and it corrects grammar and highlights changes it made, or just proofreads and I make changes manually. I can upload a novel before bed, and have suggestions based on specific writing styles in the morning. All local, perfectly suited for my own work.

Surely a custom vibe-coded mess of a web frontend for ImageMagick (it allows uploading a whole lot of scanned images, then presents a comfy web UI which allows choosing particular transformations - posterize to bilevel, trim, straighten, deskew, scale-to-page-size-and-add-edges). It runs in an ancient discarded-and-salvaged laptop.

I also use the same laptop as:

  • Livekit SFU (transporting media for Element (Matrix) calls)
  • XMPP server (Prosody)
  • STUN/TURN server (transporting media for Snikket (XMPP) calls) (coturn)
  • email server (Postfix)
  • hosting a QR scanner webpage, so I could scan QRs in PCs with minimal fuss (nginx + 1 static file)
  • and of course, since it's already there, home router (it's in the basement, so too far to do WiFi. The WiFi access point runs in dumb bridge mode)

I also run a periodic HLS video broadcast (my home internet connection should survive something like 40 simultaneous watchers, I should figure out how to distribute it efficiently to other hosts). It's too heavy for the ancient laptop, but (as it turns out, I measured yesterday), a NAS with a 4-core Intel N100 CPU just barely manages. I might switch to it, it's probably more power efficient than the current desktop workstation.

Pretty good collection for an old clunker!
