Wait, is this satire? I only noticed 3/4 through the article.

The best argument against democracy is a 5-minute interview with an average voter.

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.

without watching the video - google search is falling apart because there's a lot of shit content, a lot of bad articles being written.

and there's a lot of bad articles being written because there's a lot of authors that just want to make money from advertising, without actually caring about the content. in other words, it's advertising's fault that the quality of content is dropping. and ironically, it's mostly google's fault that advertisement on the internet got so big as it is today.

on mobile? do you really wanna know?

we live in very special times. take a step back and appreciate how transformative the recent years are.

for a billion years, life existed on earth. in the last 200 years, we invented electricity, electric cars and transistors.

I guess people are afraid of sending E-mails and doing phone-calls for this reason.

The fear of accidentally pasting a porn-link into an email is immense. So much that I clear my copy-clipboard regularly, just to be double-sure.

it's me me meee right?

Right now I can think of the buddhist "tale of the bug".

Two (human) friends died and were reborn. One in heaven, the other as a dung beetle (a type of bug) on a dung pile.

The guy in heaven tried to "help" his friend by going down to Earth and carrying his friend to the skies. But his friend refused, because the dung pile was now his home, and he didn't want to leave at any cost. Only then the guy realized that it is not heaven that makes you happy, but finding the place that you're destined for.

 

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.
