You should probably dampen your expectations on this one.
Darktable is fantastic, but the learning curve is steep for great results. It took us months to get comfortable with it after using Capture One, Lightroom, Photoshop/ACR. It's different. Our first efforts looked like crap.
For someone processing just a few files I think RawTherapee is probably easier and likely to give better results with limited effort.
Yeah, I get what you're saying. Definitely. It's not complicated for one pair of speakers in one room. For one music source. For one person controlling it.
There just haven't been any better cost-effective solutions with multi-room, control from your any phone convenience. And that's a big plus for how we listen to music. Today there are a few contenders, but many of them are also cloud dependent. Really the small number of good options in this space is proof of how good Sonos was for a long time. Well and also of Spotify causing people ditch the idea of a offline digital music library.
Edit: And to be clear, aside from the "any computer networks" part, this is what the original Sonos device did. It could work without a home network, but worked best with a shared music library on a PC. Didn't need cloud anything, internet connection, account, etc. You just hooked your normal speakers to it and it played music.
Likewise for Portugal. Its highest point is Pico, in the Azores archipelago.
Mildly what now?
No. 1970 is 0 in Unix time. The NTP RFC specifies 1900. I had to look it up!
Better to represent it as a 64-bit unsigned fixed-point number, in seconds relative to 0000 UT on 1 January 1900. It's how he would have wanted it.
And if you did, and want a fun tech project to track what species are in your yard, check out BirdNET Pi: https://github.com/mcguirepr89/BirdNET-Pi
OsmAnd will do that. If you edit the destinations you can manually specify their order. Click sort there and choose door-to-door to get the most efficient routing.
The app takes some getting used to, but it works very well, and can act as a front-end for contributing to OpenStreetsMap.
Obligatory: Debian.
But I'd be tempted to put Proxmox on it and then run containers for each function. Then you get purpose-crafted solutions for each use case, but can easily plug new functions in or shut them down based on what you decide later.
Keep the tv dumb. Don't connect it to the internet.
I like to check rtings.com for model specs and comparisons. Like, some panel types work well in a bright room, some work better than others when you are watching with a bright light source behind you. The warehouse clubs (Costco, BJ's, Sam's) tend to have good deals on midrange tvs.
Then pair it with a streaming stick of your choice. A generic Android TV stick/box would work.
LULd for sure.
