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.

The question i have is, what is the exact useage for discord here?(personally, im not a fan of the "missing content" that should have been made here.) Lets say we remove it, and replace it with irc, will it properly fill the void that was discord?
Perhaps discord is for trusted users, to have slightly more private conversations.
How would this irc client work? Do the programmers here build it, would we have to install it on our computers seprately, or would it be on 22chan itself?
Would mods give access to only trusted anons?
So, lets say everything goes well with irc. What will happen to livechan? I mean, i'm the only one who goes there daily, its like no one knows it exists. I mean, if we find somthing better like the irc deal, im fine if we get rid of it.
The irc cant take anything away from 22chan, and would it have to be built from scratch?
We have (so far, two new namefags who are seemingly very nice so far.) And maybe around ((30)) diffrent anons on 22ch. Would that be enough people for it not to be a ghost town?
We just cant just,
Rush things and making it now, i think is bad idea,
for everything to go well, it'll be a slow change.

 No.245[D]

>>244
>Perhaps discord is for trusted users, to have slightly more private conversations.
this line of thinking is bad in itself. There are no trusted users, no users with badges and whatnot, there is only anons, we are all equal here and that's what imageboards are like. You can't make friends out of chans because everyone here is anonymous(or supossed to be). It is strange when you think about it, how people interact with others without knowing one another, that feeling of connection is what we seek here.
as for the others questions I don't really care about IRC, the community is still small to fuel an active channel, I just want discord gone becuase it's a major problem in this board.

 No.246[D]

>>245
To be fair, yes, anons are equal here and that's what imageboards or at less, the first imageboard 2chan and 4chan did before the more early 2010s or what not. But if it's equal, how do mods and janitor come to where they are. Without trust and known badges for mods and janitors, that can turn this place into an anarchy place if trust is removed and the owner has too much power without any rules for anons, or a messed up place full of bad janitors and mods careless or abusing power.

 No.247[D]

>>245
I'm just trying to figure out the exact point
Of discord in the first place.i do like the mods, even though i don't really know them. I just had minor conversations to them like everybody else, and beleve that we have similar mindsets. I feel like i can trust them. Sure, i just found this place in april, and they had minor sqabbles then and there, but we all do that.
Discord just poped out of knowhere, and i'm slightly curious as to what it's being used for. ((Discord is a jewish plot to sell 22chan to google jk lol))

 No.248[D]

The thing about discord is that there's a lot of just daily conversations.
Things that don't really belong on any board or doesnt fit 22chan's quality standards.
It does give out good OCs/ideas for threads, which then are posted on the site, if it's shit-then it remains in the discord like most other things.
>>244
>30 different anons
on discord there at least 90 people, a different question is how many of them are active, but there's a lot more people who use the site itself without discord.

Moar questions
Minor answers
I'll try to explain.( i got some of the math from my ham radio textbook.) If I shine a flashlight in front of me, I will measure the beam to travel at about 300,000 km/s, which is also known as the speed of light. (Fun fact electromagnet waves "radio waves travel at the speed of light.)
And if you are moving at 200,000 km/s faster than me, and shine a flashlight ahead of you, I will see the light from your flashlight moving at the 300,000km/s. It will appear to me, as though the light from your flashlight is moving away from you at 100,000 km/s.
But when you will measure the speed of that light, relative to you, you’d think it’d be moving at 100,000 km/s as well, but instead from your perspective it will ALSO clock in at 300,000 km/s. What time it is depends upon your vantage point, and so there is no single absolute time.
Finally, because of relativity, each point in the Universe experiences time at a slightly different rate. For example, when we observe the cosmic microwave background, we find that we are moving at a speed of about 630 km/s relative to the background. That means we experience time a bit more slowly that something at rest relative to the cosmic background. it’s just a tiny bit slower, but added over the entire age of the Universe, our cosmic clock is 30,000 years behind the times.
Thats all i got. I used to have a couple good quantum mechanics books about this but sadly they were destroyed.

Unification theory says there is only one thing.
We used to think there were 4 fundamental forces, but we found out they were all the same thing. Strong em force, weak em force, electromagnetism, and gravity are all the same thing. We know that gravity is the same as time. High mass objects warp space time, which both generates gravitational forces (space) and changes the rate at which time flows relative to the rest of the universe (time). But the fact of the matter is that gravity is a myth. Objects warp time around them. Matter is sucked from areas with a high rate of time to areas with a low rate of time. It's all one thing. There is only time, and ripples in time.
But Einstein was Jewish, so I take all this with a grain of salt.

>necrobumping a shit thread
Anyway....

There are actually valid reasons why vim is not as good as some say (I am not going to comment on its philosophy or default keyboard bindings) :
- It has a lot of legacy cruft (can be fixed by switching to neovim or ed)
- Vimscript (the language that's used for developing its extensions) is crappy (can be fixed by switching to neovim)
- Vim is not POSIX compliant (this doesn't really matter in practice, however)
- Gnu Emacs has better documentation and tutorial
- It's a lot easier to customize and extend Gnu Emacs. elisp is also way better language than vimscript
Also emacs isn't nearly as bloated as some say, since Gnu Emacs is, in fact, a lisp interpreter that's just specialized for manipulating text and building a text editor, and the Emacs' core, the lisp kernel, is actually rather small and most of Emacs' functionality is build using elisp.
If you want, you can actually use evil-mode to emulate vi(m) in Gnu Emacs.

tl;dr
Install Gnu/Emacs, open it and type ctrl+h t
Install evil-mode, if you want to.

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?

 No.151[D]

>>149
As we understand it, yes, the laws of thermodyamics does imply that humans, and everything else in this universe will all end up a giant cloud of weakly interacting particles. However, scientists don't estimate that happening for another googol years or so (a 1 with 100 zeroes after it). That's plenty of time for humanity to thrive, flourish, and potentially maybe figure out a workaround for the whole entropy thing. After all, something had to put our universe into its initial high-energy low-entropy state, so who's to say it can't happen again?
