The best thing to do is just start with whatever you already have. An old gaming rig, laptop or Raspberry Pi, doesn't matter. Each will present some technical obstacle that you need to overcome (for example keeping the laptop going when the lid is closed). That's part of learning.
Self-hosting is a hobby where we gradually learn more. Experimentation is just as important as reading the docs.
The funny thing is they actually studied the autonomous left in the late 90s and learned how to copy that structure for their own groups. So they absolutely know that this accusation is absolutely bogus. But it's a great way to convince people who think listening to podcasts is "research" of who needs to go to the camps first.
I'll send you a copy if you can solve this challenge using the cypher in your official Antifa Encryption Compendium, page 67: F-C-K-N-Z-S
Gentoo is fun and a nice way to learn more about computers. Their wiki and their community was really good when I was into it, I'm sure it still is. But compiling everything from scratch is quite demanding of your CPU and your time, so it's not really something that you run as your daily driver for long.
Also lots of killers seek psychiatric help voluntarily (and are often sadly ignored). For a sane, moderately competent person it's easy to plan the perfect murder or terror attack -- it's a different thing to carry it through because a sane person also has mental guardrails.
Mossad is effective because Israelis are ruthlessly trained to dehumanize anyone who's an obstacle to their goals.
I recently visited Vietnam. As far as I could tell, young people are educated, I saw no homeless people, nobody asked me for cash. I felt safe at all times. Buildings seemed up to code. The insane inequality that you will see in places like India, Thailand or even some places in Europe (London cough cough) were nowhere to be seen.
I understand that Vietnam is still a developing economy, and that it's still a poor country. I understand that there might be issues with freedom of speech and political participation. But my conclusion is that they're doing a ton of things absolutely right, in ensuring that their people get access to basic necessities and industrializing in a controlled way.
The crazy part is that they aren't even attracted to women in the first place.
