| With severe weaponized autism, the help of several people involved, thousands of dollars spent, and countless hours wasted, we present you the largest world download project ever Never underestimate the power of severe weaponized autism! |

| ▲ | Netcob 5 hours ago | parent | next [-] | | I have a theory that the modern world would not exist without it. | | |
| ▲ | korse 4 hours ago | parent | next [-] | | >Yeah and we'd be better off. The modern world is quantifiably worse than the world we had even 10 years ago. That includes everything in software development and computer science. Rather than killing this comment, how about we discuss quantification? I actually feel this way too but do not talk about it too much and sort of boil it down to a combination of advancing in age + yelling at clouds and "Stop putting computers in all my stuff!". Can we reliably quantify that "weaponized autism", i.e. the aggressive monetization of nerds by capital to squeeze profit out of every possible corner of society (as I interpret it in a broad sense), is making things worse. Is it damaging the economy for most people? Making people less happy? Decreasing net social mobility or discrimination? Lowering life expectancy? | | |
| ▲ | fc417fc802 4 hours ago | parent | next [-] | | > Can we reliably quantify that "weaponized autism", i.e. the aggressive monetization of nerds by capital to squeeze profit out of every possible corner of society That's not what that term means. Also that comment wasn't killed directly. That user is banned. Interestingly that was his first (attempted) post since 2022. | |
| ▲ | seba_dos1 4 hours ago | parent | prev | next [-] | | That's a redefinition of the term - while there is some merit to your interpretation, it's an already commonly used term that means something else. It'd seem to me that the modern tech is significantly less "autistic" than it used to be in the prior decades and will only continue to move in this direction; and aside of that, I'm pretty sure Netcob's "modern" was meant to mean current thousands rather than tens of years. | |
| ▲ | LoganDark 3 hours ago | parent | prev | next [-] | | I feel there's reason to believe autism is one of the reasons why bits of goodness and democracy are still hanging on so tightly even in the midst of such a depressing present. (Search term: "positive nonconformity") | |
| ▲ | FrustratedMonky 4 hours ago | parent | prev [-] | | -> "monetization of nerds by capital to squeeze profit " Note. In case this is read incorrectly. For the most part the nerds are not profiting. The nerds are sitting hunched over their desk being fed coffee from a feeding tube, to keep them happy while the owners make money. And. To be more sad, these days you can't even get free coffee. Being fed free coffee and donuts, while others profit from us, is considered the golden age of computing. We loved our cozy cells, not so much these more uncomfortable ones. |
| |
| ▲ | FrustratedMonky 4 hours ago | parent | prev [-] | | I don't think this is even sarcastic. There are some theories that Autism was more useful in the wilderness. More adapted to the old world, not the modern world. | | |
| ▲ | pixl97 4 hours ago | parent | next [-] | | I think of it as a different algorithm to crawl the problem space of the real world. In a general sense, humanity needs to be generalist (especially in the past) to accomplish all the things you need to do to stay alive. Having all 20 members of your tribe geek out and stare at a problem for 48 hours straight means a bear sneaks up and eats you. But having that one oddball (hey me) fall into a rabbit hole of observation and mental computation can lead the group out of a local maxima into a new paradigm of doing things. | |
| ▲ | pavel_lishin 2 hours ago | parent | prev | next [-] | | I don't think you're wrong, but I do think that the "modern" world - which I guess I'd label as anything that happened after the invention of writing and cities - really let those individuals thrive, and let their work become very useful for the world at large. Trying to diagnose people across millennia is a fool's errand, but I'd wager a lot to say that people like Newton & Tesla were at the very least neurodivergent in some way, and they've had wildly outsized impacts on the world. | |
| ▲ | pavel_lishin 2 hours ago | parent | prev [-] | | The Percy Jackson series posited that in their magical world, ADHD is actually a strength on the battlefield, not a weakness. I wonder what a book series that tried to do that with autism would look like. (I can think of exactly one book where autism - or something close enough to it - was treated as a serious "what if" plot device, but I don't want to name it because it is a little bit of a spoiler, I guess.) |

| I'm so continuously confused why Minecraft doesn't have a show-off mode where a team of people can build something, and then someone else can spectate it, without causing undue server load. I should be able to give you a URL to some location, and when you click it, it opens up Minecraft, streams the blocks, and you're viewing it. minecraft://server/loc?w=0&x=0&y=0&z=0 w is the overworld, nether, end, etc. And if you want to set up a server where you and your friends can interact with each other and make edits, the server should be able to stream blocks from some backing server, but copy-on-write them to your own local storage. How is this not a thing? If you want to be really awesome, set it up like bittorrent, where you can share the load, so the central server isn't hammered. And if bittorrent doesn't really work as a model, then set it up so that "downloader pays" for bandwidth, plus a small royalty for the creator. As a downloader, I get to set up rate limits, etc, to not accidentally spend more than I want to, etc. This whole 2b2t would cost $2,111.04 to download from AWS, if I'm doing the math right. But that's a trillion blocks. You don't need a trillion blocks to enjoy flying around some awesome maps. |

| ▲ | zamadatix 5 hours ago | parent | next [-] | | It's easy enough for a server which wants to provide some sort of "easy viewing cool builds" functionality to do it multiple ways such that something native would only be a minor convenience and many would still just use the more customized methods anyways. 2b2t wants to provide a certain anarchy server experience which would not align with that kind of functionality, spending quite a bit of effort in the opposite direction really, so this project is more about fighting to do cool things on the server than it is about dealing with Minecraft limitations. | | |
| ▲ | accrual 4 hours ago | parent [-] | | Yes, the anarchy and inability to truly protect anything is part of the appeal of 2b2t. There was an interesting base project wherein the true coordinates were only known to the top leaders. All other builders connected through a custom client that offset the coordinates to hide the true location. If anyone became untrusted, they were simply blocked from the client and could not expose the coordinates. There was care taken to ensure the area outside the proxy was never shown, block place directions were randomized to prevent reversing the proxy, etc. The base apparently thrived for months or years before finally being discovered and destroyed. | | |
| ▲ | pixl97 4 hours ago | parent [-] | | If I remember one of these stories right, a screenshot of netherrite blocks on the floor. A member of the community calculated the block placement in the chunk and used this to determine where it was on the actual map. | | |
| ▲ | bombcar 2 hours ago | parent [-] | | That's happened a number of times on various items - bedrock patterns, nether rack layout, etc. It's all based on the seed and coordinates. |

| ▲ | GreenDolphinSys 5 hours ago | parent | prev | next [-] | | It's not in the base game, but there is a plugin that generates a map of your server and hosts it, called Bluemap [0]. It has an example. [1] I always toss it on the servers I host. [0]: https://modrinth.com/mod/bluemap [1]: https://bluecolored.de/bluemap/ | | |
| ▲ | zimpenfish 4 hours ago | parent [-] | | A +1 for Bluemap. Plus because it's actually tied into the server[0], all your wacky mods have their blocks rendered correctly instead of confusing whatever map generator you're trying to use. [0] Plus you can get live player positions, update markers in real time, etc. |

You'll be confused by Minecraft in general then. Mojang's core team seems like they never changed a bit in all these years despite becoming a billion dollar studio, for better or for worse. Last time I played it, mods can still make the game run twice as fast. | | |
| ▲ | chadgpt3 an hour ago | parent [-] | | They actually added a lot of indirection to the code soon after being acquired. Instead of an array containing the number 1 (meaning dirt) it now contains a pointer to an object with a string name and a hashmap of properties. Instead of drawing a cube in code, it's loaded from an interpreted DSL - all possible calls to that DSL are fixated at load time. The chunk generation process creates and executes a graph of micro-tasks which forms that weird pixel map you see when creating or loading the world. It transitions each chunk through about 15 different states on the way from nonexistent to fully loaded. They used to talk about wanting to store block update relationships to prevent BUD (block update detector) behavior. I didn't like it at the time, but from a certain perspective it would have been an improvement. Instead they spent their complexity points on pointless memory waste. |

How is this different from just loading your world in a server and having your friends join? > If you want to be really awesome, set it up like bittorrent, where you can share the load, so the central server isn't hammered. BitTorrent isn't going to work. You could shard it so different parts of the world are handled by different servers. But it gets complicated and Minecraft's server software doesn't support doing this out of the box | | |
| ▲ | MattCruikshank 2 hours ago | parent [-] | | > How is this different from just loading your world in a server and having your friends join? Because player location, inventory, actions, are all load on the server. That's why servers have player limits. > BitTorrent isn't going to work. You and I are talking about different things. I'm talking about serving up the raw blocks alone. And yes, I know, Minecraft servers don't support static file serving, or streaming from another source, or copy-on-write. I'm saying these are all nearly trivial to implement. |

| ▲ | 2001zhaozhao 2 hours ago | parent | prev [-] | | I have a Minecraft-compatible game engine and it'd be an awesome project to host a copy of this world that people can fly around in if there's no legal issues. | | |
| ▲ | chadgpt3 an hour ago | parent [-] | | If you seek legal issues you will find - if someone reproduced a copyrighted work in this world then you could technically be sued for copying it. How likely do you think it is though? |

| For those who don't know: 2b2t is a famous minecraft server known for its true "anarchy" configuration. You can do absolutely anything on it. Modded client, x-raying, item duplication. There are no area protections. PvP enabled. It is difficult to leave spawn :) |
| |
| ▲ | skerit 5 hours ago | parent | next [-] | | You can use a modded client, everyone does, but there _are_ some protections. So you can get kicked, you just won't get banned. | | |
| ▲ | lanyard-textile 5 hours ago | parent [-] | | I hand waved the details for simplicity, you're correct. Egregious bugs like item dupes are also patched; but while they last, they're allowed. |
| |
| ▲ | lftl 5 hours ago | parent | prev | next [-] | | > It is difficult to leave spawn :) I know 2b2t is old enough to have had many different eras, but when I heard about and checked it out in 2018, the spawn was barren, of course, but I had no problem leaving and surviving out to a pretty far distance to build a little base. | |
| ▲ | Phelinofist 5 hours ago | parent | prev | next [-] | | It is also the oldest anarchy server in Minecraft | | | |
| ▲ | tapper 5 hours ago | parent | prev | next [-] | | Thanks for the info. I was just about to post as a old fuddy-duddy WTF is this. lol | |
| ▲ | charcircuit 2 hours ago | parent | prev [-] | | >You can do absolutely anything on it. As long as that anything doesn't consist of putting anything bad in chat or a sign such as a cuss word like "shit" or building a build or map art that someone may find offensive. If you want to do absolutely anything you need to find a different server. | | |
| ▲ | chadgpt3 an hour ago | parent [-] | | that's because Microsoft said it would blacklist 2b2t (making the client refuse to join it, or the auth server refuse to auth players for it - a punishment normally reserved for pay-to-win servers but the bar has been lowering) if it didn't ban swear words in chat | | |
| ▲ | charcircuit an hour ago | parent [-] | | Considering no other server has to ban swear words (ignoring Bedrock partnered servers), I do not believe that happened. The server administration does not care so they are just trying to censor as much as they can automatically so they don't have to manually spend time looking at the server. There are other servers who are small enough to continue to have actually anarchy and who are willing to require having alternate domains to bypass the blocks. |

| 2B2T really has an extremely interesting and long history, and some of the most interesting exploits/security vulnerabilities found just for it, for example https://2b2t.miraheze.org/wiki/Nocom where the attackers had a blunt server DoS and through it influenced the server owner to report it to PaperMC, and the fix for the DoS gave them ability to track other players just as they had hoped. > In July 2018, 0x22 and Babbaj created a coordinate exploit, using the groundwork laid out in the lag exploit. The two theorized that, if the server didn't return a response for unloaded chunks, but returned a response for loaded chunks, the rough location of players in 2b2t could be approximated. However, prplz's patch returned a response regardless of whether a chunk was loaded or unloaded, requiring a second patch to Paper that would only return a response if the chunk was loaded. > Knowing that the issue would be resolved if Hausemaster reported it to Paper, likely through the method they laid out, 0x22 and Babbaj began intentionally, repeatedly, and blatantly sending CPacketPlayerDigging packets, causing the Paper watchdog process to output a stack trace, which included the line added by prplz. |

| > Providing a Torrent for this amount of data is not easy whatsoever. We are currently working on creating a Torrent that includes all data, but this may take a few weeks. What do they mean by this? I understand that it would be a download on the order of 26TiB (if we extrapolate from the recent 200k^2 download, which is a ~1TiB torrent[1]). If bandwidth costs are the issue (certainly it's an issue) they could throttle their seeding speed and let the swarm seed it. That's what bittorrent is for.

| Maybe a dumb question but since 2B2T (as I understand it) is a single instance of everyone modifying it to their heart's content, why does the download look like the standard biomes of a fresh minecraft map? |
| |
| ▲ | aeyes 5 hours ago | parent | next [-] | | It is running on a single machine so the player count is relatively low. Today the limit is ~1500 concurrent players but it used to be much lower. And of the players online probably half are bots which don't build. The map is 30Mx30M blocks so outside of the very center you'll not see that much player activity. DonutSMP is the largest Minecraft server today, the overworld is 225,000x225,000 blocks and the map is modified wherever you look. | | |
| ▲ | wongarsu 5 hours ago | parent [-] | | And because destroying other's builds is allowed most of the impressive builds are hidden in the middle of nowhere. Building within 50k blocks of spawn comes with the expectation that it might quickly turn into a crater or lava cast |
| |
| ▲ | lanyard-textile 5 hours ago | parent | prev | next [-] | | The world is mind bogglingly big; as are most minecraft worlds, but this one especially. People sprawl far to prevent PvP encounters. | |

| Minecraft world downloading is an interesting problem, because attempting to solve it by brute force (Loading all chunks in x radius) increases the problem space, because most likely not all of those chunks have been loaded before. So brute forcing it increases the amount of data you must download. |

| > A search for vertical 5x5 obsidian/crying obsidian pinwheels was also made, and only 1258 were found, with only 613 within a 25k radius of spawn. There were many more than this in December of 2025, so this is either a sign of other players removing them, or the owner(s) of 2b2t worldediting them all out at some point. I did Nazi that coming. |

| ▲ | DaSHacka 4 hours ago | parent | next [-] | | This other comment ITT has a good explanation: https://news.ycombinator.com/item?id=48181033 The TLDR is a Minecraft server with ""no"" rules, where hacked clients, item dupes, and griefing are allowed. Only thing that's really banned afaik are lag generators and things of that nature that explicitly stress the server and ruin the QoL for everyone. | |
