We obviously live in a matrix/simulated world, and it can't be older than 50 years, because before that, computers didn't exist. Checkmate christians.

this is a dildo😳
I think they were held in earlier times as a deliverer of meat, for people who lived in cities and didn't have the space to hold pig. I guess? It would make sense.
You're a plant, and capitalism is a great fire. By pulling yourself up by the roots, you're exposing yourself to the great fire, instead of hiding in the dark underground.

I imagine the reason why comments here are more constructive is because Lemmy is perceived to have a high technicality-threshhold (you have to be somewhat familiar with technology to make an account here - even though that's not true). That leads to only people with a high enough motivation to sign up here.
I think it's important that we grow and find new users, not because I seek growth, but because I seek diversity. We need more people, more opinions, and more different perspectives.
Yeah the politics is annoying at this point, it feels like 60% on the front page is politics. I'm glad when the US votes are finally over.
Yeah, I have made the experience that most communities on the german-speaking feddit.de were great, but after that had technical issues and went down for 4 months (!), the content isn't as good anymore and the users are more frustrating.

[discussion] DC (direct current) power network
(lemmy.blahaj.zone)
As we all know, AC won the "War of the Currents". The reasoning behind this is that AC voltage is easy to convert up/down with just a ring of iron and two coils. And high voltage allows us to transport current over longer distances, with less loss.
Now, the War of the Currents happened in 1900 (approximately), and our technology has improved a lot since then. We have useful diodes and transistors now, we have microcontrollers and Buck/Boost converters. We can transform DC voltage well today.
Additionally, photovoltaics produces DC naturally. Whereas the traditional generator has an easier time producing AC, photovoltaic plants would have to transform the power into AC, which, if I understand correctly, has a massive loss.
And then there's the issue of stabilizing the frequency. When you have one big producer (one big hydro-electric dam or coal power plant), then stabilizing the frequency is trivial, because you only have to talk to yourself. When you have 100000 small producers (assume everyone in a bigger area has photovoltaics on their roof), then suddenly stabilizing the frequency becomes more challenging, because everybody has to work in exactly the same rhythm.
I wonder, would it make sense to change our power grid from AC to DC today? I know it would obviously be a lot of work, since every consuming device would have to change what power it accepts from the grid. But in the long run, could it be worth it? Also, what about insular networks. Would it make sense there? Thanks for taking the time for reading this, and also, I'm willing to go into the maths, if that's relevant to the discussion.

grindset does not rule
(feddit.org)
Hey there, I wanted to make a meme to clarify what the "grindset" actually does. It grinds the human to dust.
With "grindset" I mean the "hard-working" mindset that lots of people in the US seam to have.
I think it's very unhealthy, exhausts the body, and should be avoided. People should make a living with less than 50 hours of work per week.
