  • Matrix is fragmented too, but it’s generally less fragmented in my experience (if you use a relatively well developed client). Part of this is because most people just use Synapse for their server. With XMPP, server implementations support random combinations of XEPs, and specific servers often are missing random XEPs because they’re not enabled by default and so on (thinking about ejabberd for instance here, the default config probably isn’t what most people want). I also routinely have random compatibility problems between clients pop up with XMPP. As a basic example, retracting messages is very haphazard.

    Anyway, yeah, if they standardize on server and client setup for all govt instances, it’d be fine either way probably. The clients may be somewhat janky, but they can probably fix those issues more easily when they’re only focused on one client (although unless it’s like FluffyChat and cross-platform, they may need to standardize multiple clients) and server.



  • The biggest problem with XMPP is what various servers and clients implement is kind of all over the place. For instance, most clients support an older version of OMEMO, but some clients support newer versions, and the different versions are incompatible.

    The other issue is some platforms (iOS in particular) have pretty shitty XMPP apps filled with bugs.

    I still generally like XMPP more than Matrix since ATM Matrix clients are also filled with bugs/laggy, Synapse (the main server implementation) is very resource heavy, and message syncing is kind of shit if the client doesn’t implement sliding sync (like FluffyChat). I personally think the UI for both XMPP and Matrix clients generally kind of suck, which isn’t great for convincing non-techy people to use them.


  • Except it is still encrypted to the intended recipient. As the other commenter said, WhatsApp is just another “member” of the group that you can’t see. Basically all they’d have to do is have a server somewhere functioning as a WhatsApp client. Your client sends the message to your intended recipient. It also then sends the message to their “client.” The routing server for the messages can’t decrypt the messages. All the messages are still encrypted per-member of the group and can’t be decrypted until it hits the ends, but WhatsApp is basically a mole siphoning all your messages and storing them.





  • This issue is largely manifesting through AI scraping right now. Additionally, many intentionally ignore robots.txt. Currently, LLM scrapers are basically just bad actors on the internet. Courts have also ruled in favor of a number of AI companies when sued in the US, so it’s unlikely anything will change. Effectively, if you don’t like the status quo, stuff like this is one of your few options.

    This isn’t even mentioning of course whether we actually want these companies to improve their models before resolving the problems of energy consumption and potential displacement of human workers.




    1. Over-focus on the most popular artists. There is a long tail of music which only gets preserved when a single person cares enough to share it. And such files are often poorly seeded.
    • We primarily used Spotify’s “popularity” metric to prioritize tracks. View the top 10,000 most popular songs in this HTML file (13.8MB gzipped).
    • For popularity>0, we got close to all tracks on the platform. The quality is the original OGG Vorbis at 160kbit/s. Metadata was added without reencoding the audio (and an archive of diff files is available to reconstruct the original files from Spotify, as well as a metadata file with original hashes and checksums).
    • For popularity=0, we got files representing about half the number of listens (either original or a copy with the same ISRC). The audio is reencoded to OGG Opus at 75kbit/s — sounding the same to most people, but noticeable to an expert.

    Perhaps I’m reading this wrong, but is this not a little backwards? Since unpopular music is poorly preserved, shouldn’t the focus be on getting the least popular music first?
