sherpa-onnx
Speech-to-text, text-to-speech, speaker diarization, speech enhancement, and VAD using next-gen Kaldi with onnxruntime without Internet connection. Support embedded systems, Android, iOS, HarmonyOS, Raspberry Pi, RISC-V, x86_64 servers, websocket server/client, support 11 programming languages
I used FFI in the past but sherpa-onnx is available on pub.dev these days. Look for "sherpa_onnx".
You can also point sherpa_onnx in your pubspec.yaml file to a local dir (after cloning the repo somewhere on your file system) or point to a specific git commit hash, and don't forget to specify the path because its not the root of the repo. Here's a link to the dir of the flutter package https://github.com/k2-fsa/sherpa-onnx/tree/master/flutter

rpi-imager
The home of Raspberry Pi Imager, a user-friendly tool for creating bootable media for Raspberry Pi devices.
I am fan of Raspberry Pi, and own a couple of them. This is an inexpensive device, and has a nice "tinker vibe" attached to it. The Raspberry Pi Imager makes it super easy to stage and configure. We went with it, and installed the latest version of Raspberry OS 64 bits on a 4B device I had already.

Project mention: Show HN: Proxmox VE Helper Scripts: Make managing your Proxmox homelab a breeze | news.ycombinator.com | 2024-11-12
I'm just going to repeat a bunch of what hughesjj has already said, but anyway:
OPNSense (as my household's internet interface), Unifi Controller (as my household's primary wifi), Jellyfin, Wireguard, Pi-hole, LMS[0], Frigate NVR (migrating off ZoneMinder, awaiting delivery of a Coral TPU to finalise this), couchdb (as Noteself[1] back-end), nginx (serving a handful of sites for my own entertainment), Mailu[2], Calibre[3], various other in-flight experiments (which Home Assistant will soon become, Bitmagnet DHT scraper).
Most of the above are docker instances hosted on a small number of VMs hosted on two (or sometimes three) physical machines running proxmox.
