  • Prices capped have nothing to do with nuclear energy and everything to do with stupid EU price policy.

    France used to have a monopoly by a state owned company on electrIcity: EDF. But everyone knows that’s terrible, and private market is the way to go. At the time, electricity in France was the cheapest across Europe, but it’s still terrible because… well that HAD to change!

    In order to introduce some competition, generation, network and “distribution” (billing…) activities were separated.

    Then private distributors (again: billing companies with 0 generation capabilites and 0 grid network) were allocated some quota of electricity from the nuclear electricity generated by EDF at low cost.

    In addition, and that’s the European policy: electricity price on the market would be set at the cost of the most expensive generator at a given time. Example: 100% nuclear today: cost is set at cost of nuclear. 95% of electricity from nuclear, 5% from gas: 100% of the electricity that day is billed at cost of gas! 80% nuclear, 15% gas, 5% coal: 100% of the electricity billed at cost of coal!

    Why? So that the priate newcomer would get huge benefits and be able to invest in electricity generation. But: there was 0 constrain in doing so, so they just rack up benefits at the expense of EDF and clients! Even better: since they get such low prices from their quota, they’re cheaper than the EDF split distributor company. So at some point, their quota was insufficient for their client’s demand. Time to invest… hahaha! No I’m kidding: time to ask for a bigger quota, of course granted by Macron and his team.

    Then came Ukraine invasion. Uh oooh! Gas price exploses, even the “distributors” start to feel the pain. What to do? Well, kick out their clients! Refure to renew contracts, or ask for such a ridicuously high price to make sure they just go! EDF’s hisorical distribution company is legally obligated to take them back. And that’s where the 2nd joke kicks in: EDF gave s much quota of nuclear electricity that they no longer have enough for these clients they have to take. No worries: the “distributors” sold back the electricity quota… at market price, ie mostly gas price!

    With the price of gas multiplied n times determining the cost of the whole production, it became unbearable for clients. That’s where genius Macron and Lemaire (Minister of Economy) set a “shield” (cap) on the bills. It’s no shield nor cap. It’s actually the state of France paying the difference in the bills between the actual bill and the cap they set. That’s public money!

    And again, that money didn’t go to resources. It went straight to “distributors” (rather call them parasites).

    For sure, the heavy maintenance work on the nuclear power plant done at the time didn’t help. They decided to do it on all plants at once (another bad call) and it lasted longer than planned.

    But the price issue has nothing to do with nuclear and everything to do with stupid policies.

    And now, lesson learned (not): Spain and Portugal got out of that absurd elecricity market. Germany and France (and many other countries) made a few changes and keep going. Because competition with multiple private actors in electricity is good. Can’t you see it??




  • In these companies, does anyone check the licenses in details to make sure using them is ok for the company?

    Meta will get at least the metadata: meaning they will record who was in which call connecting from where.

    For example, if one member is visiting a client, Meta may be able to infer the relation between the 2 companies.

    If any of the people in the room click “report”, then the discussion is sent for review without the encryption protection

    I’m pretty sure their user agreement translates to “you agree to let us do whatever the f*ck we want with the data you’re purposely disclosing to us”.

    And last but not least: if Meta decides to wipe the archives, any info get lost?

    There a reasons large companies ban unauthorized apps to talk about work.








  • 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.
