One question I still have is how quickly posts and comments propagate across the Fediverse. How can I be sure the comment I’m writing actually shows up across other instances, and how long after I write it does it take on average to show up other places?
For instance, when I look at the list of comments on this thread sorted by both Hot and New, directly on Lemmy.ml versus on my home instance of Lemmy.pt, I don’t see the same set of comments. Not all of the ones from Lemmy.ml appear to have made it over to my instance. Is there some sort of eventual consistency mechanism in the system?
spoiler for the base gameThe sun station. After way too much time figuring out how to get there, the music, and the story stuff to read there? Such a good moment.
spoilerIt’s a shocking revelation when you discover the sun station doesn’t even do anything, when up to that point you might think to yourself that it’s the sun station that causes the supernova.
I have infrequently quoted lines from Futurama in the past and not a single one of those quotes has ever been rewarded with a delicious raisin. I feel as if I have been bilked out of my raisin.
Plex and a web app I wrote for a Twitch community I moderate.
Plex is on a server in the Netherlands and the web app is just AWS. I would’ve hosted on some spare hardware but my internet is notoriously trash and I didn’t want to risk it going down while people are playing in the app.
Plex I might move onto a NAS at some point but I’m just too lazy lol.
I’ve only been on mastodon for a couple of days, but yes it is active, and depending on what you’re after it might we worth it. For me, it seems to be a nice mix of keeping up to date with things and people I already know, and at the same time stumble upon (related) things I did not yet knew about.
You will have to put in some effort to follow people/accounts/hashtags, but that’s kinda fun. Just try it out!
All networking gear is Unifi. UDM Pro, USW Aggregation, USW Pro 48 PoE, U6 Pro, U6 In-Wall, 3 USW Flex Minis. 10G SFP+ connections between UDM Pro and switches.
Very impressive. I gotta ask, how is this feasible cost-wise? Mostly as in licensing for vshpere. I know you can get pretty far in windows server with evaluation keys, butI run an ESXi server on eval mode cuz I’m cheap and have to reset the license every 90 days with some commands and reboot 😅
What is the scale of your network, like is this all just in your house?
A small cloud server + a domain name costs less than a Netflix subscription. The developers have taken care to package lemmy in ways that are relatively straight forward to deploy, so a dedicated person with a small amount of experience can have an instance up and running in an evening. As long as a few percentage of users are willing to pay a netflix subscription to keep a server running, the financial burden would be spread.
I think this underestimates how users will naturally gravitate towards more centralized instances, or they’ll give up because the bigger instances are closed. Someone’s gotta pay for it, and it’s going to cost more than a Netflix subscription. Servers aren’t cheap.
This also ignores that the system isn’t horizontally scalable at all, so scaling up gets even more expensive

(This is purely my personal opinion, of course!) In the scenario in which a few large instances dominate, the idea of the fediverse failed. One may estimate the likelyhood of success or failure given how they expect humans to behave, but in the end experiment beats theory. I think that for the fediverse to work a significant cultural shift has to occur, but I don’t think that it is an impossible shift. I would like the fediverse to succeed, and so I choose to take part in the experiment.

Yes, that might cause some serious issues. The project is still in an early-development phase, and I don’t understand the technical aspects well enough yet to be able to identify whether there is obviously a fundamentally invincible barrier when it comes to scalability. My optimistic hope is that the developers are able to optimize horizontal scalability fast enough to meet the demand for scale. If it turns out to be impossible to scale, then only rich enough parties would be able to have viable instances, and that could be a reason for failure.
This is what I think, but if anyone understands it differently please correct me.
Vertical scalability refers to scaling within a single instance. More users join and they post more content, increasing the amount of disk space needed to hold that memory, network bandwidth to handle many users downloading comments and images at once, and processing power.
Horizontal scaling refers to the lemmyverse growing because of the addition of new instances. The problem in this form of scaling is due to the resources that an instance has to use due to its interactions with other instances. So, you may create a small instance without a lot of users, but the instance might still need a lot of resources if it attempts to retrieve a lot of information (posts, comments, user information, etc) from the other larger instances. For example, at some point a community in lemmy.ml might be so popular that subscribing to that community from a small instance would be too much of a burden on the smaller instance because of the amount of memory required to save the constant stream of new posts. The horizontal scaling is a problem when the lemmyverse becomes so large that a machine with only a small amount of resources is no longer able to be part of the lemmyverse because its memory gets filled up in a few hours or days.
