  • I use to say “all extremes call for their opposite”. Since almost no information ever transpires about this whole scandal, the opposite is to release all the names to the public. It was to be expected. If we were trusting the justice system, this would seem inappropriate. But we have what we have, and making the whole list public is the only guarantee we have that not one of the “bad” guy can escape public’s attention. That of course, is valid only if the list is comprehensive and some names have not already been taken out.

    It is indeed unfortunate that a lot of people who didn’t deserve and didn’t want any bad attention will get some.

    I’m not saying I agree with the move. I’m saying it was to be expected.

  • Nuclear plants consist mainly of a shitton of concrete (and only the best sort is good enough). The production of that concrete causes a terrible amount of carbon emissions upfront.

    Actually, if you compare them to solar or wind at equivalent service, it’s not that straightforward:

    Renewables installed capacity is nowhere close to their actual production, nuclear can produce its nominal capacity in a very steady way.

    Wind turbines also need a lot of concrete, and much more metal for equivalent output. Solar panels need a lot of metals.

    Renewables need a backup source to manage their intermittency. It’s most often batteries and fossil plants these days. I don’t think I need to comment on fossil plants, but batteries production also has a very significant carbon emission budget, and is most often not included in comparisons. Besides, you need to charge the batteries, that’s even more capacity required to get on par with the nuclear plant.

    With all of these in consideration, IPCC includes nuclear power along with solar and wind as a way to reduce energy emissions.



  • “Collapse” meaning what, exactly? Do you mean run out of storage from the volume of content, or that processing all the messages is too taxing?

    Years back, I setup a Synapse’s server on my personal server (Yunohost). At some point, I joined the “big” Matrix room. Bad idea: RAM and CPU usage went through the roof. I had to kill the server but even that took forever as the system was struggling with the load.

    But don’t just take my words for it:

    Last comment is from less than one year ago. I was told things should be better with newer servers (Dendrite, Conduit, etc.), but I’ve not tried these yet. They’re still in development.

    How does it scale differently than Matrix?

    The Matrix protocol is a replication system: your server will have to process all events in the room one or more users attend(s) to. There is a benefit to this: you can’t shut down a room by shutting down any server: all the other ones are just as “primary” as the original. Drawback: your humble personal server is now on the hook.

    XMPP rooms are more conventional: a room is located on one server. That’s an “old” model, but it scales.

    That’s for the host. For other attendees, it’s much lower.

    I don’t think I atteld any public room out there with 3k users, so I can’t report my first hand experience, this is the best I found. But I never had to check for load issue on a small server (running Metronome and many more services).

    Out of curiosity, why do you say this?

    I don’t use the Fediverse the way I engage with individual people. If I want a closer relation with someone, I don’t want to be bound to yet-another-messenging system, let alone on multiple accounts

    And another reason is I may not want to be bothered by people I don’t know, regardless how much I could appreciate reading and/or exchanging with them in the Fediverse.

    Ignoring or declining requests from strangers can leave a lot to interpretation and then frustration. Remove the button and no one is tempted to press it the be disappointed with the outcome. Less drama.

    And that’s only considering well intended people.

    But these are my humble 2cents.


  • I think it’s worse than that. We humans are inherently selfish and self-preserving.

    People who live far away from any coal mines do not feel threatened by coal, because it will not impact them directly (besides fu**ing up the planet, of course, but that’s another issue humans have with big pictures and long term effect correlation to present small scale actions).

    But most people can’t tell where a nuclear plant can be built, so it could be close enough to expose them to a risk of disaster?

    Therefore: “Nuclear is more dangerous than coal (for my personal case)”


  • What I don’t like with Matrix is the load it puts on the server. It basically copies 100% of a room content to any server having one or more users registered in the room.

    So if you’re on a small server, and one user decides to join a 10k+ large room, your server may collapse under the load as it tries to stay in sync with the room’s activity. This is deterrent to self-hosting or family/club/small party servers.

    XMPP, on the other hand, has proven to be highly scalable, has E2EE, federation and some bridging services.

    The only thing XMPP does NOT have is a single reference multiplatform client with all basic features for 2023 (1:1 chat, chat rooms, voice/video 1:1, and voice/video conference) than anyone can use without wondering if the features-set is the same as the persons you’re talking to.

    And while we’re there: I’m not even sure I want a messaging account linked to any of my Fediverse accounts…
