  • Solar and wind are not cheap enough

    Solar on itself works between a few less than 8 hours and 16 hours depending on the solstice you are the nearest of.

    And that’s the theorical best.

    Reality is efficiency will drop during summer because of the record temperatures each year and in winter we are seeing more sun (Haven’t seen snow in 7-8 years btw) but the production is still relatively low.

    If you want it to run 24h/24, you need to build batteries which adds more carbon and cost. And that’s on top of the maintenance cost for the panels themselves.

    Wind can work 24h/24 but you cannot predict it long term.

    Wind too strong? We stop the plant. Wind too weak? Subpar production. And with climate change, your expectations on a few years basis can change very rapidly.

    So how do you make sure we produce the same amount of energy with certainty? You build oversized farms more expensive than what you theorically predicted.

    There is also the problem of land.

    A wind or solar power farm requires a lot of land comparatively to nuclear if you want to approach the same power production.

    That land can be occupied instead for housing, farming or anything else.

    Comparatively, a nuclear plant can easily be circled in a few minutes by foot and produce over 1 Tera Watt of energy.

    Once you compound everything, nuclear is the best solution we have at our current technology level but ridiculous anti-nuclear propaganda acts like it is a thing from the demon.(My green party almost closed several nuclear power plants. During the start of the russian war. To open gas power plant instead. Like WTF?).

    So what will the rich people do?

    Refuse to build nuclear because their fearmongering to push gas/oil backfired on humanity and refuse to build solar/wind because we could build 50 Disneylands in the same area.

    I would love them to eat their shit and choose either solution still. But it’s only a dream.


  • I just accept our fate.

    Humanity will probably realize we seriously fucked up around 2050 and near the end of the century mass migration will lead to a death count much bigger than WW2 or the chinese civil wars.

    The only grace is that most of us reading this thread will die from various reason before the second stage.

    I will still do my part by reducing my CO2 footprint but unless we find some miracle technology producing nuclear power plant levels of energy for the cost of a charcoal power plant, shitty world leaders and corporations will ruin everything for fake wealth.


  • Let’s not forget the unmentioned income thanks to gathering all that user data.

    The real value of Youtube (and social medias in general) is not the raw revenue they generate.

    It’s being able to be able to predict what will trend in advance to sell ads to anyone, anywhere. Which is proven by their 200+ billions in revenue from ads from all services.

    It’s extremely likely that in an alternate universe where Google doesn’t own YouTube, their profit today is lower than what they currently have.

    But like you said, poor YouTube is not making money explicitly on its own so they’ll use it to justify any cost increase attempt when they already know what the real money maker is.









  • In addition to what the other commenter said, Mozilla doesn’t have the will to improve Firefox into a market contender.

    They get a lot of free money from their competitors to prevent legislations from attacking chromium for market monopoly which makes them prioritize making Google happy more than their users.

    They also have very controversial opinions regarding actual useful features such as progressive web apps (where support was given exclusively on Android but after a lot of complains). You can’t make your browser into a market contender if you act like Safari on PC.

    10 years ago when we had a 3 way market, Mozilla actually cared about making a good product.

    Nowadays, they are just Google’s shell company to keep Chrome’s dominance away from the anti-competivity law suits.





  • How is that a rip off? You pay 20€ once and get the ability to sideload any UWP app and develop for the console.

    Compare it to both Nintendo and Sony where:

    • You have to pay multiple times the price of the console for the dev kit
    • You don’t own said dev kit
    • Their SDKs are not publicly accessible
    • You have to sign multiple NDAs on top of all those issues
    • Assuming you have no problem with all this, you can be rejected as a developer for any reason

    Considering how locked consoles were and still are (Except for the PS3 “other OS”) period. Being able to get a decent current gen console, that doubles as an emulator, with development capabilities for an additional 20 euros is a gift, not a rip-off.





  • It’s more that UBI is just not financially possible for any country.

    I live in a country with the highest tax rate on the continent and with just 20% of our population as pensioners, the situation is just getting worse and worse even though 49% of the population has a tax rate between 25 and 50% (+13% from welfare taxes). Just with this small percentage, we are spending 20% of our budget in pensions. More than any other area by at least 5% of our national budget.

    If the state now had to pay an UBI to 69% of our population on top of this, the very minimum to pay off the UBI without going bankrupt would be to sell off the free healthcare and public transport in their entirety. And I’m assuming a small UBI of 500€/month (Not even enough to rent a 1 room appartement with utilities in some areas).

    UBI would destroy any country’s budget for what? Landlord increasing rent to match the UBI, corporations increasing prices to match the inflation and people wasting that money when it could have been put to use to increase renewable energy production, improve education, …

    UBI is only a good idea in paper and you only need to look at the public expenses of most European countries + have a basic understanding of capitalist greed to see it.

    The database isn’t really the problem in the current state of things. The server is because:

    • Until 0.18 there was no caching (for the UI) and the poorly implemented websockets
    • The developers have admited that they aren’t proficient in SQL, in which case, why not using an ORM instead? Sure, they aren’t perfect but they will do better than the average developer at scale.
    • There is no queue system for activityPub requests
    • Because there is no queue, user requests and federation have the same priority when it shouldn’t and one can bottleneck the other
    • Live inserts are used meaning that regardless of the DB used, performance is going to be killed since inserting data 1 at a time several times a second is a major waste of resource

    Tl;dr: It’s trying to do everything and not that well. So users suffer because they have to share resources with non-UI related tasks.

    The database suffer because it has to do an insert of 1 object X 50 times in a second when it could do it once for all 50 items.

    Federation suffers because you can’t offload it to a seperate machine farm whose job will be to receive and send ActivityPub requests and send/read data from the correct queues to do so.
