Why do we have two modes in cpu(user and kernel) since we still can still easily harm computer with userland programs?

I have never dug into low level things like cpu architectures etc. and decided to give it a try when I learned about cpu.land.

I already was aware of the existence of user and kernel mode but while I was reading site it came to me that "I still can harm my system with userland programs so what does it mean to switch user mode for almost everything other than kernel and drivers?" also we still can do many things with syscalls, what is that stopping us(assuming we want to harm system of course) from damaging our system.

[edit1]: grammar mistakes

  • I think what "god" does mean for me, you and others are different. Also same goes for "believe" and "you". I believe, these kinds of topics are way out of our minds' league and even we could comprehend and discuss those things(god, reality, logic etc.) we still would be using wrong tools like language and our current logic system. So both the tools we use, and our intelligence is not enough to answer this question.

    But still, if you want a yes or no answer; I would say no without hesitation.

  • If all federated communities could decide upon to regulate same rules, every one of them could be moderated by their own moderators. But the problem I see here is the things that's being federated is in reality server itself which means it would be impossible(not sure but at least not necessary) to do such a thing. But anyone can easily build an app to collect posts from same communities, it does not require to play with activitypub, just lemmy api.

  • They have no idea what they are down voting. They do it just because it is against sync. You are just stating we should support foss devs. They literally are just bunch of fucking idiots that probably came here just by following others. It would be awesome if they could just fuck off from fediverse and go lurk in reddit.

    Where can I learn algorithms and data structures?

    I know this can be easily searched over internet, but I want to know your experience. I don't want a medium article listing algorithm courses.

    I found Algorithms from Princeton University in coursera, but course is too old and many resources they have provided are not working right now. I would apprentice it if you could share more of an video type resources because I am not good with programming books, I can not focus them.

    Thanks in advance...

  • For every single way that you may be using to reach out the internet, there will always going to be an exit node which won't be able to hide out itself. You may still use ssl or whatever you want (cant think of anything else that widely used) to encrypt the connection, as you normally do on your computer every time like you try to reach out a server with https. But I still take some actions that are not being encrypted between me and other side which I don't want to be related with me. So basically, I don't want some of my traffic to be exposed to ISP or any possible other threat. In order to provide that, I find a vps provider which has enough internet traffic to not use ISP to access internet(like many big tech companies do), and buy a vps from there anonymously(of course my ip is being exposed here but it is also being exposed on other vpn services and I am not doing something that important to make my ip so much important to hide). Afterwards I setup a wireguard or openvpn (depends on your needs) server and connect it from my pc. Which basically works like a vpn service that many people subscribe.

    As far as I can see(if I am not mistaken somewhere), if you have a problem with this kind of protocol, then you have a problem with vpn services itself. And if you have a problem with that, and need more anonymity, you can connect to a public wifi and then a vpn and then a distributed network like tor.

    To what extent can I be skeptical? What is our limit of comprehension?

    cross-posted from: https://lemm.ee/post/3172656

    Couple of days ago I saw a post about on atheist community about a quote saying atheist can't base their morals on anything.

    I commented that if religion didn't accept some premises like god, they wouldn't either. Some said I am wrong and downvoted me. So I decided to post here about to what extent can I be skeptical about premises, to see where I am mistaken (or commenters).

    Before that post, for a while I had an idea that even the analytical truth/necessary truth (whatever you name it) like "a is equal to a" are premises which can not be proven (since they are the basics of our logic, which will we be in use to prove claims) even though they seem us to be true by intuition. They just have to be accepted to be able to further think about other things.

    So my question is since we can question the correctness of basics of our logic and cant find an answer, we can not justify or learn anything. Also, there lays the problem
