North America, South America, central America, the Pacific islands... The list goes on.
This isn't some kind of metaphysical crap, they respected the land so it would provide for them. Respect in this context means you're mindful of what you take, and you plant the seeds to help more grow down the line. You hunt the herd, but you also chase off predators and make sure it stays healthy.
Some of them didn't have to take food with them when they traveled, because over generations they stocked the forest with edible plants. They knew how to, but they often didn't have to plow the soil because their ancestors artificially selected for the environment into being great for humans
They surrounded themselves with food forests. The uneaten food draws in animals too, making for easy hunting. No worries of depleting the soil, you don't have to work the land, you just walk around and gather what you need
It's very efficient and probably what humans did in most places that had good conditions. You get to spend most of the day on your hobbies and hanging out. They had trade networks from Argentina to the Pacific Northwest. They had advanced math and their technology was moving at a reasonable speed. They had hundreds of thousands of people, and plenty of room to grow
Farming has one advantage - a small group working their asses off can feed a much larger group. That let's you field big armies with bupply lines, and then you can turn the "savage" land into farmland, and extract profit from it while denying their food source
Their situation wasn't unique, every indigenous people either had forest gardens or managed herds of wild animals. They even had empires like the incas and the Maya, who were able to build roads, pyramids, and floating cities with huge populations
That's why they started wars when people started killing buffalo for profit and leaving the meat to rot - they were willing to share because they had more than enough due to generations of work, and profiteers slaughtered their food source for no good reason. It wasn't moral outrage, it was an extensional threat
They rejected the idea of ownership of the land because it wasn't theirs to exploit, it belonged to future generations. And that's why our generation is fucked, because capitalism isn't about efficiency, it's about maximization
So what's going on is the adversaries continuously hitting the lemmy.world server. On its own, a DDOS like that would be manageable - they're much more defeatable these days
But they found request paths that run expensive db functions, giving them enough bang for their buck to make an impact, even tucked behind cloudflare.
As for mitigation, cloudflare and a larger server help, but ultimately lemmy needs some refactoring - right now it's very liberal with the database calls. It needs to divide those up and get more granular with API calls, look at what can be optimized on the DB side, maybe do some caching/memoization... Basically, it needs to become a more mature piece of software in a hurry
Going further, there's things like horizontal scaling - there's even thoughts of how we could leverage the nature of the fediverse to share the load through federation.
I'm a dev, I don't know much about administration so I'm not sure how you could help, but there's plenty of work to go around. I think a database expert would be the most useful right now.
There's messing with configs to tune everything for better performance - that's out of my expertise, but I'm under the impression that there's some significant gains to be had there
If it's in your wheelhouse, you could look at different technologies that might give better performance - the current stack seems like it was chosen mostly with ease of development in mind, if you could make a strong argument for changing some of it out it might get traction.
As far as cyber security in general, if you want to get started - step 1 is basically locking things down, and then setting up monitoring tools and getting experience with them. Basically reading logs taken to the next level. I'm pretty sure they have that handled here, but this problem will never go away
