  • Imo part of the problem with mastodon, at least in my experience, is that it’s sold as a twitter replacement while still being devoloped and largely populated by people who don’t like twitter (because it’s too “toxic”). This means that you can’t really have the twitter experience on mastodon by design so people coming from twitter mostly wanting to get away from musk bounce of. Bluesky has been a more successfull twitter replacement and I think that’s largely because it basically is twitter with feeds.

    I think that mastodon should either commit to being more like twitter (which it is propably too late for at this point since I don’t imagine that their current userbase would be into that) or people should stop trying to make it the new twitter and instead let it be it’s own kind of different thing.


  • It’s gonna go public eventually, this is like a closed beta kind of thing. The purpose seems to be more to get people curious about it and foster a certain culture which I must say that they’ve been pretty effective at. They strategically handed out invites to a lot of black twitter users for example, which is smart since black twitter has historically been an important cultural force on the internet



  • Depends on in what way you’re looking for a youtube alternative!

    I think peertube might be fine if you’re looking for a way to host your own videos, but it’s propably not a good place to just browse for video content the way you might with youtube. I think the most solid alternative for that is Nebula. It costs like a dollar a month IIRC and has a couple big name video easayist kind of types. It doesn’t really have anything to do with the fediverse or anything, but a majority of it is owned by the creators and from what I understand it is more generous per view than youtube, plus it has a buissiness model that doesn’t rely on serving you adds and selling your data.








  • While I think that the article is correct in stating that mastodon isn’t currently a serious competitor to facebook, it’s possible that it (or something else based of activitypub) might become that one day. I think that there’s a decent chance that facebook might want to prevent fediverse spaces from potentially becoming serious competitors, and even if that’s not the main reason why their implementing activitypub, if e.g. mastodon ever does get to a point where it can challange meta (which I think most of us are hoping!) then facebook will use the position of power they will have over activitypub to try to prevent that. I think it’s a misstake to give facebook any power of our spaces because that means essentially giving up on the idea of an internet not controlled by large corporations like facebook.






  • Right now fediverse is mostly made up of techy people - which is fine! But there are many other kinds of people you might potentially want to interact with online. Threads could bring in normies and celebs to the metaverse. Normies are a mixed bag - this includes your racist uncle but also your really cool and funny friend who can’t be bothered to set up a mastodon account. Celebs are a source of real world influence (I’m including politicians and journalists for example in this category) which is obviously attractive. I’m gonna miss cyberbullying local politicians on twitter, and it would be nice to be able to continue doing so through the comfort of e.g. kbin.

    I get your point and I largely agree but it isn’t that hard to see the appeal of threads for me. I don’t think it’s gonna work out in the end though so I really hope they mostly stay of the broader fediverse.



  • (typed this out yesterday before @ZickZack s excellent answer, but couldn’t post it at the time due to maintenance…)

    No, you’ve got it wrong. This is a fairly common missunderstanding which is perpetuated by a lot of coverage about the topic being sloppy.

    You could argue that there is a grain of truth to the idea of processing multiple possibilities at once, but it’s a bit more complicated than that and the way it’s usually presented leads to people building a bad intuition of how it works. If you do get in to the nitty-gritty of Shors algorithm it feels to me at least a bit like a weird hack that shouldn’t work at all or at least not be faster than the normal way to compute prime factors. It isn’t a general speedup, just in certain cases where you can exploit quantum mechanics in clever ways.

    Of the top of my head the SMBC comic about it is actually pretty good. This article makes basically the same points, but a bit more elaborated (note that it was written a while ago so the part about the current state of quantum computing is outdated). I noticed that Veritasum put out a YouTube video which I haven’t watched, but he is in my experience good at explaining physics and math so I think that there’s a good chance that it’ll hold up. I remember liking this Minute Physics video about Shor’s algorithm too, if you wanna get a better understanding of it.

    I should clarify that I’m not a quantum phycisist, I’ve just done a couple of internet deep dives on the topic but I can’t say that I fully understand quantum computing at all. I do think my understanding of it is better than the one in this article and others like it.



  • This is article is missleading about how quantum computing works.

    Superposition increases the computing power of a quantum computer exponentially. For example, two qubits can exist in four states simultaneously (00, 01, 10, 11), three qubits in eight states, and so on. This allows quantum computers to process a massive number of possibilities at once.

    Quantum computers aren’t faster because they “process” multiple “possibilities” at once. Quantum computers aren’t any faster than regular computers when it comes to general purpose computing. You can exploit some interesting properties about quantum computing to solve certain problems asymptotically faster, like with Shor’s algorithm.

    This means that the time to solve a problem as the size of the problem grows scales better. Using Shor’s algorithm, the time to factor a polynomial is proprtional to (log N)^2 log log N, where N is the size of the input data, instead of the fastest known non-quantum algorithm which takes time proportional to e^(1.9(log N)^(1/3)(log log N)^(2/3)). Note that the majority of problems that we would maybe like to solve using a computer don’t have any fancy quantum algorithms asociated with them and as such are no faster than a normal computer,

    Given a large enough problem that can be solved with a quantum algorithm, a quantum computer will eventually outperform a non-quantum computer. This does not mean that quantum computers can solve arbitrary problems quickly.
