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 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.

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.

and all kinds of other obvious incorrect stuff when a normal request looks like

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.
