I agree to a point, but this is also how you get communities that are REALLY easy to squash. Because they're fragile and incoherent. Bad actors can easily overwhelm them, astroturf, go after hosting....etc and small self funded communities won't have the manpower, tools, or resources to combat it.
You want to build a strong community that lasts, and is resilient.
So how do we make our communities more resilient, well resourced, less fragmented, and also accessable for member growth?
We could self-host using our own computers and infrastructure, and secure them from hackers.
Can we?
For real, can we assist with hosting using our own servers as distributed nodes? I have business fiber and plenty of dedicated compute just hanging around. I'd happily host nodes to assist with stability, redundancy, and general compute/networking.
You literally can just download the Lemmy program and install it on any computer you want to use as a server. I used to run Mastodon servers a few years ago, and it's not without its hurdles, but with some Linux knowledge and a little bit of server admin knowhow, you absolutely could.
You'd need a computer you're gonna use as a server, put Linux on it, then install NginX or Apache on it, then Lemmy, then set everything up and get a domain name to attach to the computer's IP. Question mark, profit. It might be a bit of an oversimplification, but with some research and work, it can be done.
I mean to contribute distributed resources to existing instances. Not so much make new ones. Assuming Lemmy has a protocol for distributed resources built on something like the raft consensus algorithm.
I'm mobile ATM, so not at home, trying to learn as I go. The goal being by the time I'm home I'll know enough to provision resources if such a concept is a thing.
I have a whole cluster at home with business internet, so plenty of ready to go resources 🤔
Lemmy isn't distributed like that. Each instance does its own user and community management with local storage and processing. The community content - posts and comments - gets distributed to any other instance that asks for it, and that instance then presents it to its users. The result is that the content is replicated & distributed across many instances, and the load of presenting that content to users is shared.
So, running your own instance, where you're the only user, will cause that instance to fetch whatever communities you've subscribed to via API. That probably reduces, slightly, the load on those servers, but it's not going to be a huge effect.
Running your own instance and getting a dozen or a hundred friends to use it instead of lemmy.world or feddit.de, on the other hand...
Ah gotcha.
Isn't that a hard barrier/limit to scale then (as well as support)? Would it even be possible to run say a 5 million user Lemmy instance with a single write postgres DB (I assume compute can be load balanced, you can utilize CDNs for media content, can heavily cache the API, and that it supports read replicas?)
Nevermind 10, 30, or 50 million user communities 🤔
Though at that point you're essentially just lighting your bank account on fire for infra costs.
