  • my take is that 1. you don’t need equal supply year-through because big consumers should be able to sleep and reduce their energy intake in the winter. yes i know that is complicated, but sleep is also complicated in nature and evolution still pulled through with it because it does pay off in the long term.

    So you’re trying to advocate we should put millions of people on virtual unemployment during winter to save energy? Who will pay for that?

    Do you think it’s honest to compare nuclear price all-included LCOE to the solar and wind LCOE* (* = not accounting for the tens or hundred of billions of unemployment subsides each year to account for forced shutdown because of power drought)?

    secondly, storage can also be renewable biomass. i have some napkin math sitting around somewhere on my disk that says that about 5% of the yearly energy demand can be covered with basically non-cost “waste” biomass that’s basically being burned to get rid of it today. I actually wanted to write a longer post about it in the !bathtubthoughts@discuss.tchncs.de community, i just couldn’t figure out how to properly present my calculations yet.

    First thing: biomass is about 200-250g of CO²eq per kWh. Burning biomass is polluting, and thus is not a viable alternative to nuclear, hydro, solar, wind, and the other low-carbon power sources we should aiming for.

    Even if your calculus are correct, if I take the example of a country like France which has a +30-50% increase in power consumption for 5 months during the coldest months than in the rest of the year. And it’s not because of industry, it’s because we heat up with a lot of electricity, even if we still need to convert a lot of fossil-based heating to low-carbon electricity heating.

    But the solar production at the time has a -75% decrease. Wind is basically non-consistent through the year.

    So when we need solar the most, to heat up in winter, a phenomena that will get even worse when we decarbonize heating, it just does not follows up. And wind drought during very cold weeks definitely happens regularly.

    So we NEED interseasonal power storage to make full-renewable working, at least without huge capacities in hydro-electricity.

    And we’re not even close to achieving this kind of gigantic power storage, which is why Germany, the biggest advocate for solar and wind with more than 40% of its electricity coming from it, and has no hydro, is still one of the dirtiest electricity in Europe. Because it still burns gas and coal to compensate for solar and wind lack of reliability.


  • But will Fusion ever be cheaper than solar?

    Will solar with interseasonal storage ever be even feasible?

    People like to throw LCOE around, occulting that running countries with solar (and wind) power is plain science-fiction and nowhere close to change, while nuclear (at least fission) is empirically proven to work reliably, even for cheap, costing less than 200 billions of euros in the span of 60 years in France for example.

    When you don’t have enough sun (or wind), you either have sufficient backup in hydro or solar, or you burn coal and gas.

    Wether you like it or not, some people don’t have the luxury to stop fighting, even more so right now with so-called democratic governments that brutalize, lock up and torture people for their opinions, their sexuality or their skin color.

    Ignore these debates if you wish, and disconnect from social networks if you need to rest. But don’t call for people to stop fighting when their very existence is put at risk by people like DHH, that Framework decided to support.



  • That happens all the time. There’s no way to guarantee that it won’t happen with any codec or really with anything.

    Yes, so there’s no reason to hold back on releasing updates, since it could very well happen on AV1.

    It is very expensive to defend against even when the claim is bogus.

    The principle behind AV1, once again, is to have a modern codec that is out of reach from patent trolls. Those who are part of the AOM consortium, which developed this codec, have all contractually agreed to unconditionally license all patents they hold that are necessary for the implementation of the codec.

    And those who are not part of the consortium and who would like to claim patents relating to the AV1 or AV2 codecs would have to face the legal teams of the companies part of said consortium, including Amazon, Alibaba, Adobe, AMD, Cisco, Google, Intel, Microsoft, Mozilla Foundation, ARM, Huawei, Samsung, Tencent, Meta, Nvidia, Apple, Netflix, and other large companies.

    The AV1 and AV2 codecs, after perhaps H264, are the most secure codecs available today in terms of patent trolls. Nobody has both the will and the means to attack it.





  • A country like France would need around 20 truly massive STEPs like Grand’Maison to provide for a single winter night (~60GW for ~14h). That’s 100-200km² to put under water, a massive ecological disaster, and a massive hazard.

    And you must find a way to produce enough energy and find enough water to recharge your STEPs in the next 10h before the next night.

    And that’s with the current France needs, having only 25-30% of its energy being decarbonized electricity, it’s getting even worse if we go to electrical heating and transports.

    Powering an entire country without hydro, geo, nuclear or fossils is just plain science fiction. And hydro and geo cannot be built everywhere, so realistically, you either go fossils, or nuclear to have clean electricity.

    And you can verify it empirically: even with trillion invested in solar and wind, the only countries which have decarbonized their electricity have massive hydro/geo/nuclear.

    I already answered your second paragraph: Jellyfin holds no sensible data.

    And there is no central server gathering data from all users, an hacker would need to find and break in multiple Jellyfin instances, to get useless data from 1 to maybe 10 users each time.

    And Plex is not easier to install and secure than Jellyfin.

    My Jellyfin is behind a Crowdsec + Cloudflare proxy with geoblocking and other protections + Reverse Proxy with additional protections, in a rootless Docker container with no access to the Docker socket, and has only access to a mounted folder which contains just downloaded movies and shows. The effort to break in is high, the reward very low.

    But the most important difference between Jellyfin and Plex is that neither Jellyfin devs nor Jellyfin instances have any personal or credit card information from their users, and therefore are way less a problem if hacked into.
