Creating of the universe

How do you anons think the universe was created?
Do you think it was made by some higher power? Maybe a scientific phenomenon, or perhaps it was just always there.
All thoughts and beliefs are welcome, religion, scientific research or just personal beliefs, they're all just as valid to the question. After the universe was created, how did all the atoms and matter get there? What caused all of this matter to just appear? Excited to hear your thoughts.

Conway's Game of Life

Ever since I discovered it, I was fascinated by Conway's Game of Life. For those of you, who are not familiar with it: it is a cellular automaton with two dimensions on a rectangular grid with each cell having either the state "dead" or "alive". From any given state, the next state is computet by a very simple set of rules:

-if a cell has less than two neighbors it dies
-if a cell has two or three neighbors it lives on
-if a dead cell has three neighbors it becomes alive
-if a cell has more than three neighbors it dies

The attached image shows what patterns emerge. You can see still live, oscilators and gliders fliing around.

More info in these formations on wikipedia: https://en.wikipedia.org/wiki/Conway%27s_Game_of_Life

But what is even more fascinating is that people built very complex structures in Game of Life. Like spaceships, cannons or even functioning CPUs.


I always wondered how these are made as every structure in Game of Life is extremely fragile. Do people really spend hours/days/weeks on building these or am I missing something here?

Long-Time Nuclear Waste Warning Messages

Nuclear waste lasts a long time, like super long. We're talking longer than all of recorded history by orders of magnitude. Right now, the only way we know how to deal with this waste is to bury it somewhere and put up a bunch of signs that say "there's a bunch of radioactive material here, so put away that shovel." The problem is, language changes over time. English from a mere 500 years ago is nearly indecipherable to anyone without a college degree. How do we tell people 10,000 years in the future to stay away, without dedicating the resources to constantly maintain these burial sites? What if we get sent back to the stone age by a meteor impact, massive pandemic, or nuclear holocaust? What then?
The Sandia Report gives 9 messages that need to be conveyed:
>This place is a message... and part of a system of messages... pay attention to it!
>Sending this message was important to us. We considered ourselves to be a powerful culture.
>This place is not a place of honor... no highly esteemed deed is commemorated here... nothing valued is here.
>What is here was dangerous and repulsive to us. This message is a warning about danger.
>The danger is in a particular location... it increases towards a center... the center of danger is here... of a particular size and shape, and below us.
>The danger is still present, in your time, as it was in ours.
>The danger is to the body, and it can kill.
>The form of the danger is an emanation of energy.
>The danger is unleashed only if you substantially disturb this place physically. This place is best shunned and left uninhabited.
Humans are notoriously curious, so it's rather difficult to keep them out of the metaphorical cookie jar. Especially when said cookie jar is filled with the curses of ancient gods. Written language is useless, as has been covered, and word of mouth is dodgy at best. So it's down to symbols to communicate the message of "bad, stay away." These range from fairly tame, like a grimacing human face, to badass, like so-called "hostile architecture" (pic related)
So, my question to you and the purpose of this thread is, what is YOUR solution to the problem of communicating danger to future civilizations? Or any other cool facts related to human use of nuclear energy and its repercussions

IRC & Discord

So discord is taking IRC place for a lot of communities including 22chan, what do you think about it? Have you made the jump yourself yet?
For me I find it annoying that people with no knowledge of /t/ are more and more using Discord, it became the norm to have a discord account. I think it can evolve to the point of including business meetings and the such and this made it almost a normie thing.

Distributed internet

Have you ever heard of the distributed internet? The idea being that instead of having to rely on a server you share content with other users directly.
Torrents are the most famous example of this. However what if a distributed structure was used not only to share anime and cracked games but also to provide actual websites? Like another internet. What if there could be an internet without servers?
Here are some of the projects related to this I've seen around:
>Ipfs: https://ipfs.io/
Slightly improved torrents really. Removes duplicate files in the network. Has ipns, which allows to have a constant link to mutable content -> we can already have static web pages with this
>zeronet: https://zeronet.io/
Peer to peer, allows you to have mutable content as ipfs, but also supports having sites updating real-time. But most importantly it allows you to have websites where other people than the site owner can post content, which means you can have sites such as youtube, forums, imageboards, twitter (hopefully not. Jk they already have a thing similar to it). All without servers. Noice. It also has tor integration.
>freenet: https://freenetproject.org/
Again peer to peer, allows for websites and for user-content sites too (it says it has forums). Citing them:
>Communications by Freenet nodes are encrypted and are routed through other nodes to make it extremely difficult to determine who is requesting the information and what its content is.
Also has some functionality to hide that you are using freenet called "darknet". Seems similar to zeronet except more concerned with security and anonymity

old shitbox needs new drives

I have an IBM eServer xSeries 345. It's been gathering dust in the basement for awhile now and I'd like to turn it into a data storage server running linux.

However, the drives are only 18GB each. Are there terabyte-sized drives compatible with a system this old (made around 2001) that I can buy for a reasonable price? If so, what would make a drive compatible? Anything besides the connector?

I found this project recently. It's and alternate client for Discord (and slack) and although not open source you could probably trust it more than ((((discord)))). It still seems to be in beta though, there are some unimplemented features and logging in is finnecky. But once you get it working it's great for power users.

Does the 2nd law of thermodynamics imply the extinction of humanity?
You see, entropy always increases in a closed system, such as the universe. That means that the entropy will get higher and higher. But human bodies I'm pretty sure aren't peak entropy. At one point to grow further entropy will have to destroy all human bodies. Any sorts of computer human replica too, and I'm pretty sure anything that can move on its own/think. Entropy is disorder, and those two things require some order.
Am I wrong? Is there something I'm not considering?
