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 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...

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 of do we really understand the same thing from the same concepts, and does language limit us?

If I am mistaken, which is highly probable, please correct me and don't judge. I am not much of a philosophy reader.

I would really appreciate it if you could share some resources (video, article, book, anything...) about limits of our understanding, logic, language and related topics.

Thanks in advance...
