  • Sure, in a ultra-consumerist world, everybody buy all things new. Now that hard drives cost a kidney, you buy refurbished ones, and you realize that it’s not that bad, especially if you use the right mitigations.

    And that’s a trend that may grow and spread to other things, considering that mondialisation will get increasingly difficult due to geopolitics troubles, and petrol becoming costlier over the next years/decades.


  • Bought 4x10TB drives 2 years ago for 385€ on eBay, from a 20+ years old seller account with tens of thousands of good reviews with a long warranty on drives, to build a local media server + some other services for family and friends.

    One was dead on arrival: they just sent me another one, no question asked.

    I have them set-up in a RAIDZ1 array, so I can have one disk down and still have the system up.

    I have my services and critical data backed up daily (with about twenty snapshots that go back to months before) with Restic to both a Hetzner storage box and a local external drive (both tested for recovery).

    I have one disk that failed me a few months ago: sent the disk to the seller, they tested it, and sent me a new 12TB drive because they didn’t have 10TB anymore.

    Added it to my ZFS pool, and since then, everything is ok. My few users didn’t even notice anything going on: downtime was minimal, performance was ok.

    If more than one disk fails, I have my data on my external drive. If my external drive fails, I can download everything from Hetzner. In both situations, I wait for new drives, replace the old ones in the pool, and restore my snapshots. The downtime is annoying, but I’m not running a business so nobody is paying for anything, so it’s ok.


  • french power plants are getting old

    Most of them still have 30+ years of life in them

    can’t handle oncoming increasing heatwaves

    Not this again… French nuclear plants has not being stopped because they can’t handle heatwaves, that’s plain bullshit, but because of ecological precaution, which on top of that, seems to be useless

    and regularly have major accidents

    Also plain bullshit

    source(german)

    That explains a lot of you take your sources from anti-nuclear organizations

    in the age of wind and solar and cheap batteries it is not necessary and much cheaper to build renewables.

    It’s not the age of wind and solar. We’re still in the age of coal (35% of electricity) and gas (22,5%). If we talk about energy at whole, it’s even worse : 30% is petrol, coal 26% and gas 23%. If you think that solar and wind will stay cheap when everybody will compete for the large amounts of metal and other sources needed to build them, and when we will run out of petrol to mine and produce them all, you’re lying to yourself. Nuclear in comparison require very little resource to build and to operate them.

    And that’s without taking into account a basic fact: we don’t have enough room to build enough STEPs and we don’t have enough resources to build enough batteries to run entire countries on solar and wind. Looking at costs in 2026 is just meaningless when we’re actually talking about science fiction.

    also: french nuclear energy is only cheap because it gets heavily subsidized. a kwh of renewables is about 7ct, a kwh of nuclear is in reality about 49ct

    Another bullshit: EDF has been making billions of benefits out of nuclear every year for decades (except in 2022). They even made 10+ billions of euros of net benefits the last 3 years.

    And EDF is subsidizing France, not the contrary: the State forced EDF to take a huge part of the cost of the Bouclier Tarifaire, and EDF paid billions of euros of dividends to the State as well

    Where do you even get the “media” part in it?

    I’ll quote myself because I already answered that: « Media is the plural of medium, which means “intermediary” ». That’s the textbook definition of the word media, and the consensus about what it means.

    Whatsapp is the middleman/platform, thus intermediary (= “medium/media”), between two people socializing. I don’t understand what you don’t understand.

    A social network is social media that allows to form groups or communities. Two people communicating is not a network, the whole point of a network is interconnection between members of a group.

    totally made up definition from your part

    You forgot the “from your part” that is quite important. Language is a consensus, you just invented your own definition and pretend that it is the consensus.

    And anyways, if “social media” and “social network” is the same, why have two different terms for it?

    They’re not the same, it’s the square/rectangle thing. A social network is a kind of social media, all social medias are not social network. You could argue that Whatsapp is a social media but not a social network (but the frontier is getting blurry with groups and these kind of things).



  • 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 [email protected] 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.
