  • This isn’t an application on a Mac, but it is a demo website for a series of qr-code libraries so it will work on any platform. It isn’t as convenient for people unfamiliar with QR codes, but if you need full control over the encoded data then this works really well.

    The website does the generation in JavaScript so you don’t need worry about hammering some guy’s API if you needed to generate a lot of QR codes.

  • Now I think I see what you are saying. People have suggested that Lemmy needs a separate protocol to connect with other Lemmy instances to more efficiently synchronize. Gossipsub could do that. It would also be nice if each Lemmy instance only needed to keep a minimal amount of data at any one time to service the clients that connect to it while the rest exists in the swarm.

    I still don’t think that you would want a phone to function as your server and your client, though. All that coordinating takes bandwidth and processing power. Phones are ill-equipped for that. Also, usually to p2p effectively you need to be able to make direct connections through firewalls. Opening your phone directly to the Internet would be a bad idea, plus I doubt any phone companies would let you do that. Without a direct connection, you would need to proxy your connection through some server somewhere and deal with bandwidth costs. Might as well just connect to a server as a client.

    Maybe the final solution is software like Lemmy running with decentralized identities via the Nostr protocol that is federated out using Gossipsub.


  • Then the p2p network is really the “server” and the phone is still just a client. I’m also not sure that a p2p network could be queried very well because something would have to be able to produce aggregated and sorted results. It isn’t like pulling one file from a swarm. It would be like a blockchain and the phone would have to download the whole dataset from the p2p network before running queries on it.

    What you are talking about sounds kind of like the Nostr protocol. It is a distributed social network trying to solve the same problem that ActivityPub is but in a slightly different way. All the events are cached on multiple relays and the client applications query those relays looking for information that gets aggregated and sorted on the client however it wants.


  • ActivityPub is all about pushing content around to subscribing servers. It sort of expects the subscribers to always be online which would not work for a phone. Servers could resend missed events, but essentially you would miss every event that occurs while the phone is asleep or doesn’t have the app running.

    Also, every event that occurs needs to be processed and stored whether or not you are actively looking at it so it would be a huge battery drain while it was running.

    It is definitely a service best run on an always-on server with a client application in a phone just asking the server for the latest stuff on-demand.


  • I have also thought this is a good idea. I think that the ActivityPub standard should have a required field that lists a copyright license. Then a copyleft style copyright should be created that allows storing and indexing for distribution via open-source standards, and disallows using for AI training and data scraping. If every single post has a copyleft license then it would be risky for bigtech to repurpose it because if a whistleblower called them out that could be a huge class action suit.

    A good question is if a single post can be copyrighted. I think it could. Perhaps you would consider each post like a collaborative work of art. People keep adding to it, and at the end of the day the whole chain could function as a “work”. Especially since there is a lot of useful value and knowledge in some post threads.


  • I’m confused. Isn’t the commission that is paid just a cut of the profits from sales? The 85% not paying commission would be because their app is free. Apple’s argument is that they are providing a huge platform and infrastructure for app developers; many of which are utilizing it for zero cost (except the annual $99 developer fee).

    If someone then uses that infrastructure to make money then Apple takes a cut of either 15% or 30% to help sustain the whole thing. Those numbers are argued to be too high although they are basically in-line with the mark-up of most goods and services.

    The real complaint is that Apple doesn’t allow alternate app stores that would compete, and theoretically push down the commission to whatever the free market determines is reasonable (and presumably below 15%). Apple, of course, argues that they do it for safety purposes. One way to offer lower commissions is to have less strict screening processes to save money. This could end up being a race to the bottom of quality which may not really benefit users.



  • I have recently been thinking that copyright and patents should be enforced until the creator made back their money plus a set profit; like 30%. The reason for this is that it makes it similar to physical products which are often sold at cost plus some profit; usually around 20-50% depending on competition.

    Doing it this way has some interesting side effects.

    • It puts creative production on par with physical production.
    • It requires transparent accounting.
    • It covers the hard work required to develop something while not giving windfall profits to minor discoveries that just piggyback off the work of others.
    • The more that is charged for a protected product, the quicker it enters the public domain. If you needed to keep a copyright for a long time then you wouldn’t charge a lot for it which is still beneficial to the public.

    There could be some nuances. I’d imagine that there would be some threshold amount that covers smaller items. Maybe everything is covered for the first $200,000 or so. If one was claiming more than that for R&D then they would have to produce accounting demonstrating that amount. That way smaller creators aren’t necessarily burdened like a large corporation that does R&D for a living would be.

    Obviously numbers could be fudged, but it could be set up so that is difficult. Accounting could be adjusted. Perhaps quarterly or yearly reports have to be made on which projects money was spent on. That way there would be a paper trail that would make it harder to pretend like more work was done on something than actually was.

    Just a thought.


  • It sounds like you are referring the federation. When something is posted to one server, that server has to then propagate it to the other servers. That process is not instant; especially in large servers. In fact, right now with the Lemmy software it is a bit of a bottleneck that will be worked on soon. issue/3230

    Another possible reason for this is caching. Browsers and servers cache pages to a lot to reduce load and make things go faster. That means that I sometimes you can see an old version of a page for a bit until it refreshes. Set correctly, a cache shouldn’t get too stale, and using the browser refresh button could fix it.
