Whoa, thanks! OP here, I'd thought nobody really cared about this stuff and considered this thread dead
In any case, I guess I'll post something new so that the bump isn't empty
>a fun story about a magic switch
>my personal experience, how I found out about hacker culture
I was just a kid when I... sigh... became curious about becoming a "hacker", in the mainstream meaning of the term. The reason I think was that at the time I heard about the "Anonymous hacker group" and obviously was extremely fascinated by it. I mean, they were fighting for good, and were epic hackers! And they did it all from their bedrooms, and were otherwise pretty ordinary people like me!
Thing is, surprisingly enough on one of the websites which claimed to be associated with "Anonymous" I found a link to catb, specifically the "how to become a hacker" page
And that page encouraged me to learn more about programming languages, which had a big impact on me, as discovering langs other than java, python and c exposed me to new and different ideas that I probably wouldn't have heard much of otherwise until much later. It's also indirectly what got me into emacs. The culture itself really inspired me at the time too, and even though sadly I didn't become a hacker, I think those ideas influenced me growing up. Later my focus shifted to other things, and gradually I forgot about all this up until recently, when after revisiting some old places and reading some new things I made this thread


This thread reminded me of a relatively recent video Mutahar made

Have you tried Waifu2x? It's meant for anime pictures, but it would probably work on a non-photo like that one.

There is a criminal organization in Brazil using NSO Group's Pegasus to infect devices for hack for hire, to incite terrorism, blackmail people, produce illegal pornography and assist in assassinations. They also have other advanced malware, like UEFI implants and even persistent implants for Kindle and Raspberry Pi. Plus face/voice recognition on every camera and microphone they can get into, in public or private places.

Brazil won't do anything to stop them. Only the FBI, CIA and NSA can stop them.

There is also the possibility that they were engaged on the hack of Bezos' smartphone.

If you know of any security researcher who wants to reverse engineer the exploits they are using, I am more than willing to help them.

If you want a story about how they operate, I am willing to work with you to expose them.


What? sure i guess, please elaborate, i would like to know the full story. do you have any documents or news stories related too?

Recommend me a good antivirus program that will protect my PC from viruses and cyberjews
6 replies omitted. Click here to view.


back in the old days, I used to use Avast, as it was considered the best of the free ones. Nowadays, I hear Avast is basically malware itself, so I wouldn't recommend using it. If you are using Windows 10, the one built in is probably good enough for everyday use. The main way you would get infected would be installing/running shady software. Don't download cracked/pirated software is the best way to avoid malware. Also, use an blockader. Drive-by malware ads are the main other way that malware spreads these days, and that is incredibly easy to defeat.

If you don't think the built in Windows anti-virus is good enough, you can try uploading downloads to virustotal.
It scans the upload across dozens of different anti-viruses.

Also this.


try kaspersky it's free


>Don't download cracked/pirated software is the best way to avoid malware
You can as long as from you get them from the right places

Why do malware warnings scare me so much?
1 reply omitted. Click here to view.


cuz ur a pussi


becuase you don't know much about malwares


>Why do malware warnings scare me so much?
They are designed to be scary. They make them scary to keep normalfags from clicking the "go to the website anyway button." The do this because they have a vested interest in keeping malware off of normalfags computers. If a normalfag can easily click past the warning, they will, and they will inevitably get infected. When they get infected, the normalfag blames the antivirus for not protecting them instead of themselves for deliberately not following the warning. This blaming of the antivirus would reflect poorly on the company and also allow malware to spread further. Thus, they have to resort to scaring normalfags as part of the systems protection.

This is the same way that religion works. Make up a scary God and punishment in order to keep normalfags from harming themselves.

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?

The answer on stack says it takes 11,520 generations per clock count (I guess it means for 1 minute)
Also that simulator site allows to set the framerate. So: (from a comment on stack)
>24 FPS with a Generation Step of 8
>24 x 8 x 60 = 11520
Should work. I don't how precise it is, and you'd need to start it perfectly on time, but it would be fun


As far as I understand it, the "step" parameter is the amount of steps per frame. So with a step value of 512 and fps of 20 that is 10240 steps per second.

The Problem is, that it displays only every 512th step. If it took only 3600 steps for a minute it would show every step with 60fps (60 steps per second * 60 seconds in a minute).


Sadly that can't work with the current design
>At the very top, there's the clock. It is a 11520 period clock. Note that you need about 10.000 generations to ensure the display is updated appropriately, but the design should still be stable with a clock of smaller period (about 5.000 or so - the clock needs to be multiple of 60).
You'd need to redesign the thing for a smaller display, or it would all just be a mess

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?

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 civilizationPost too long. Click here to view the full text.

Kind of related, I was watching archaeologists excavate an old Roman town in England somewhere. It was live-streaming on the internet and they dug up the blacksmith and the air filled with lead fumes and they all had to leave and cancel the live stream.


I think that problems like these will sort themselves out. Say that theoretically all knowledge of the present is destroyed. The descendants of the survivors build their own primitive cultures, with traditions and taboos. People who dwell in radioactive locations will become sick and die. Stories of those peoples sickness will spread and locals will come to understand such a place as dangerous, cursed, etc.: a place to avoid. Rebellious idiots break the taboos and go there and die, and are a sacrifice to the survival of the traditions and thus to the society. And the cycle continues.

You can avoid the linguistic problem by image-idea rather then word-idea key pairs.
I would do something like this:
Put three of four statues of humans with waste
One where human is healthy, digging
One where he comes close the marked item
One where he is sick and close to death
They would go one taller than the other, or only be viewable in such a way that the sequence would be pretty clear. One other suggestion I've heard was to incorportate folk stories with clues to these dangerous places, but in my opinion people would forget the important details quite fast.

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

Really? I didn't know about that. I mean about it being distributed
> And a bunch of people hosted cp and stuff Like that unknowingly because of that.
That sucks. But I'm sure you can make moderated p2p networks, so I'd say it's the moderators fault. If someone posts cp on a normal ib it will be hosted there till a mod removes it. Same on p2p


>muhhhh decdntrlaization

fuckoff with this shit. It never fucking works, its communism for content.


I've just found out that an entirely distributed search engine exists!
I'm curious to try it but it requires to download it and set it up
