3G generally refers to the 3rd generation of cellular communication (the frequencies and ways a phone communicates with cell phone towers). Phones can’t really be updated between them, the modems in them are made to support what they support and thats it.

3G is being shutdown gradually world wide to make room for better 5G speed and coverage. 5G is the newest generation of cell communication.

3G networks debut in 2001 and 2002. 5G networks started being deployed in 2019.

I’m glad lemmy’s fetching seems to be better: once a community is on your instance its there and you get everything except stuff from servers you’ve defederated with.

I recommend avoiding political communities in general. too many extremists on either side of the political spectrum.

btc is bitcoin yes. coinbase is one of the bigger exchanges so that’s fine

if you live in the USA crypto makes your taxes more complicated; the IRS wants to know when you buy and sell it and how much you got it for just like traditional investments.

all you need to do is refresh the page after the error message appears and you’re golden, no big deal

its the internet, they are. Putting it behind cloudflare and locking down the firewall to only allow their ips has filtered out pretty much everything. its free and pretty straight forward if you own your own domain.

check your nginx access logs, I’m sure they’re full of people poking it.

It has the power to run a one user instance, I’m sure it would run into issues trying to squeeze a normal amount of people onto it, but a handful sure.

I run everything off an external hard drive

lemmy can run on a decent variety of hardware, just has to be some thing left on 24/7 and exposed to the internet (be careful, the internet is a hostile place… mine was getting scanned and poked constantly until I put it behind cloudflare and then locked the firewall down to just let in cloudflare), and of course more users take more powerful hardware.

For my personal just me instance though, I’m just running it on a Raspberry Pi 4 I run some other stuff on. Uses less than a gig of memory.

you should see kbin , I had a poke at that the other day and it needs php, postgres, nginx, mercure, rabbitmq, supervisord and also nodejs.

I got close, but I couldnt quite get things working the other day. Had it to the point I had an ugly unthemed version up some of the time.

its not bad at all, just the rust based backend and the nodejs based ui and it only needs postgres and a reverse proxy like nginx to send traffic to the right place.

some instances let anyone create their own community (lemmy equivalent of subreddit)

I’d recommend tech experience before setting up your own lemmy server ( instance); the internet is a hostile place with random pcs poking servers 24/7

don’t worry, its already fixed. should be in the next release.

On my personal instance I’m running a build with that and its properly giving nice recent posts ( including the OP)

you dont need to login to search.

if you do find something you want to do more than simply view, copy the post or comment url, and then search for it on your home instance for it to be pulled over so you can properly interact with it

itl only search within communities at least one person on your instance is subbed to yes. and subbing doesn’t pull in hardly any previous posts, mostly just new ones from that point on

use something like this to help find communities, and perhaps retry searching on the home instance of a relevant community to search its entire history

there arn’t any sync problems currently. You’re posting just fine from kbin.social onto lemmy.world and it federated just fine onto my own tiny instance and so many others.

its more that with more existing users its more likely any particular community will have already been pulled into that instance by someone else already.

I run my own instance so there’s nothing on my all feed outside of communities I already sub to because there are no others on my instance.

As a reminder, instances only get content from a community when someone on that instance is subscribed to it ( so to get it in in the first place they’d search !community@instance then subscribe to it).
