Ceph, GlusterFS, and I suspect SeaweedFS (but I haven't used it) expect high speed, low latency connections to their peers. So they won't work well over the internet.
There's some info floating around about using IPFS as the backend for Jellyfin, which in theory should allow you to share media between friends, but I haven't tried it.
Another (mostly) retired Unix sysadmin here. I never could make Python work in my brain, but last year discovered Svelte/SvelteKit and really like it. I'd always kinda hated on JS, but actually it's pretty nice these days.
So I'm neither a marketing or sales guy, though I have done a bit of both.
What I'd say is that if you are trying to create a successful business / product ... you need to be considering marketing/sales before you actually build anything. The classic tech founder mistake is to build something nobody wants. Or that costs more to produce/support than you can sell it for.
I've got a funny story about a dotcom era business I worked for, where an amazing tech team built this product that was miles better than anything our competitors were doing. We spent 18 months getting it all built out etc. And then the business guy came in and ran the numbers and pointed out to us that our return on investment was longer than the replacement cycle of our hardware. Oops ..
Mostly I mean the assumption that's easy and that you can just "do sales and marketing" after the fact. Sales people are too "sales" to work for free. :-)
I see tech people doing this to sales, marketing, and bizdev people sometimes as well. I've created this thing, it's all done I just need someone to sell/market it ...
Yeah, so worth it! The first time I moved a service to a new box and realised all I had to do was copy the compose file and docker-compose up -d ... I was sold.
Now I'm moving everything to Docker Swarm which is a new adventure. :-)
Another old school sysadmin that “retired” in the early 2010s.
Yes, use docker-compose. It’s utterly worth it.
I was intensely irritated at first that all of my old troubleshooting tools were harder to use and just generally didn’t trust it for ages, but after 5 years I wouldn’t be without.
I'm really liking the look of stalwart, but it's quite new. Mailu seems to be pretty nice, good features and not too resource heavy. Mailcow does everything, but it's a 🐷.
Thinking this through a bit more. It's the server (eg. Signal) that sends the push notifications to Apple/Google. So turning off notifications on your phone presumably means that that Apple/Google doesn't send them to your device. However they are presumably still be going from the server to Apple/Google (because how would Signal know that you've turned notifications off on your phone)?
There's an old saying, "Unix is user friendly, it's just fussy about it's friends."
