Theres many platforms to choose on peertube, does making account on one platform still works on other peertube platform? ELI5 the peertube

It's been a while since I was taught Chemistry, but I was reading something the other day and I couldn't quite get my head around the concept.

So the periodic table shows elements with their atomic numbers (protons) and atomic weight (protons + neutrons). Isotopes have different numbers of neutrons, like carbon-12 and carbon-13 which I believe would have 6 and 7 neurons respectively.

So why is carbon-12 the 'default' option, shown on the periodic table? Is it to do with which version of carbon is the most common? I don't understand how we decide what makes up the pure version of an element/ it's atomic weight as shown on the periodic table

I understand that the Romans were unable to conquer Scotland so they build Hadrian's Wall (which explains the survival of older cultures there). But as far as I know they occupied Wales and Cornwall, so how is it that the Celtic culture (language etc.) survived in those places?

I want to build my own cloud with Raspberry Pi, but I don't know which hardware to buy.

Will it be enough if I buy a Raspberry Pi 5 and two SSDs?

I've been trying to keep up with it but I just don't understand how he profits from this scheme?

Also why is it sometimes called a federated ID? Does it have to be an email address or could any value work?

So almost every GDPR cookie consent banner out there has a section for "legitimate interest" cookies that they can leave on by default and you will inadvertently accept even if you choose "Reject all" unless you go to the detailed settings and disabled those too.
Some of them have dozens of legitimate-interest cookies.
I read some articles about what they are and why it is allowed to keep them on by default, but they were very vague. So can someone explain it to me like I am five?

Do they get some kind of real-time feed that tells them "hey this URL popped up in the web today, but it is a tracker, so block it", or is this exercise is mostly helped by the crowd ?

I keep seeing references to RICO in the Trump Georgia stuff. What is it and how is it relevant to that case?

I'm completely out of the loop.

I understand that in end to end encryption the message is encrypted and only the recipient has the key to Decrypt it. How is the key transmitted, and how can the key not get intercepted with the message?

I feel like whenever I see the ampersand on this website, it’s followed with “amp;”. I’ve noticed it other places on the internet also. Why does this happen? Is it some programming thing?

Just for a test: &

For example, anyone could use Let's Encrypt to get a trusted certificate, so what makes this trustworthy? Or why not trust everyone that signs their own certificates with a program like OpenSSL?

In a similar vein, why can we not use the technology of RAM to prolong the life-cycle of an SSD?

Why is the recent news around the LK-99 room-temperature superconductor such a big deal? What material impact would those findings have on electronics and modern technology?

I remember back in the day when people would "Jailbreak" iPhones, but never really picked up on what they were doing other than that it let them do stuff that those of us with "non-jailbroken" iPhones couldn't do.

Are they just booting another OS, e.g. android? Also: why haven't I heard of it in a while? Is it not possible on newer iPhones?

I know gator-aid and its like advertise that they have lots of them. And I know sometimes I feel bad if I sweat a lot and just drink water. But are they just advertising... salt? Are there different kinds of electrolytes, and if so are they interchangable?

I use manjaro linux and I installed brave using the AUR repo. I keep hearing stories about how Brave is just another ad tracking software like Chrome. What I don't understand is why, like specifically.

Because I downloaded Brave from here. The code for Brave is here. I can build and install Brave and it will be the same as from AUR right?

Ok let me list my questions:

1. If the sourcecode for Brave is open and is all I need to compile and run the software then where's the tracker. The code base is honestly to big and high level for me and my professional abilities but I'm not that great of a programmer, I'm just really good. If there are ad trackers or adblock-blockers then I should beable to see it in the code right? I just need help actually seeing these lines of code.
2. I've used wireshark to monitor Brave in isolation and I couldn't see traffic that I would disapprove of. It is also very realistic that I just don't know how to recognize.
3. Just because Google maintains chromium doesn't mean that chromium browsers have to track you. Chromium is opensource and it shouldn't cost much to comment out trackers. So wasn't this already done? And if not can we actually see the lines of code that track us?

Really what I'm looking for is help coming to the conclusion that these browsers are that bad for me myself.

I think I understand why this is bad, but I am not confident in my technical understanding of the mechanics here. Will appreciate an explainer :)

looks like rendering adblockers extensions obsolete with manifest-v3 was not enough so now they try to implement DRM into the browser giving the ability to any website to refuse traffic to you if you don't run a complaint browser ( cough...firefox )

here is an article in hacker news since i'm sure they can explain this to you better than i.

and also some github docs

I like shopping in book stores. There's something about wandering the aisles and waiting for a book to jump out at you that I can't get shopping online. Unfortunately, whenever I compare the price of a book Amazon has every in-person store beat, often pricing their offerings 30%-50% lower (or around $10/book in my experience) even when I go to a large chain like Barnes and Noble.

How is it that Amazon is able to afford to offer the books so much cheaper and also support all of the infrastructure involved in shipping it to my doorstep compared with in-person stores?

I know every distro has its own package manager, some of them share the same package manager, you can even install other package managers.

Besides the source there getting the content from, the formatting of the download and compilation phases, and maybe even a specific programming language; I still can't wrap my head around why there need to be so many?

What rule says that every distro needs its own package and manager to install any package?
