  • Nice article.

    why bother? Why I self host

    Most of this article is not purely about that question, but I dislike clickbait, so I’ll actually answer the question from the title: Two reasons.

    First of all, I like to be independent - or at least, as much as I can. Same reason we have backup power, why I know how to bake bread, preserve food, and generally LARP as a grandmother desperate to feed her 12 grandchildren until they are no longer capable of self propelled movement. It makes me reasonably independent of whatever evil scheme your local $MEGA_CORP is up to these days (hint: it’s probably a subscription).

    It’s basically the Linux and Firefox argument - competition is good, and freedom is too.

    If that’s too abstract for you, and what this article is really about, is the fact that it teaches you a lot and that is a truth I hold to be self-evident: Learning things is good & useful.

    Turns out, forcing yourself to either do something you don’t do every day, or to get better at something you do occasionally, or to simply learn something that sounds fun makes you better at it. Wild concept, I know.

    Conclusion




  • This is a web service that returns the ActivityPub data for any URL that returns an ActivityPub message. For instance this post (https://lemmy.ml/post/19589249) returns:

    {
      "@context": [
        "https://join-lemmy.org/context.json",
        "https://www.w3.org/ns/activitystreams"

    Prepend https://browser.pub/ to the URL you want to check: https://browser.pub/https://lemmy.ml/post/19589249






  • I’m going to throw this out there not being sure how true it is, but I find it interesting to think about.

    XMPP is much more widely used than Matrix if you count WhatsApp (Meta/Facebook). ActivityPub is much more widely used than AT Protocol and nostr combined if you count Threads (Meta/Facebook). So reasons why people aren’t talking about XMPP include not wanting to recognize that Meta is hugely influential in this space and that most people don’t talk about the underlying protocols of the services and tools they’re use at all leaving a self selected group of people looking for alternatives with traction that don’t depend on Meta. Outside of WhatsApp, there’s not a lot of traction with any particular XMPP implementation. And none of the XMPP implementations have a Discord-ish organization of chat rooms that’s popular and familiar right now. Matrix has both right now (although I don’t think it will ever be more than a small niche in the mobile messaging space).

    I’m fine with using Matrix for what it is. There are programming language communities that have been very helpful for me and a number of Lemmy related communities that have been nice to be a part of.

    It cuts both ways. Less commercial interest means only hobby level development (which can be high quality, but is typically slow and unpolished for users).

    So you can spend your energy on making up the gap between the ease of use of the commercially supported software and the pure volunteer projects or you can have free time for things you’re more interested in and jump ship when they squeeze too hard for cash.
