Yeah you can host your own blog on the fediverse. I’ve started similar attempts, in fact, such as !aniki_blog@feddit.org . I intend to expand it, but it takes time getting used to this type of personal web space.

normies
Honestly some normies would help us talk about something different than US politics, linux and being trans femboys. Honestly, we’d have some diversity in content. I’d like that.
Btw how do we stand on just blatantly copying and reposting material from reddit? I missed the announcement talking about that.
Thank you for this well-thought and balanced viewpoint. It took me 19 days to process all the information.
So basically, I was wrong when I assumed that inverters had an efficiency of around 50%. That misunderstanding comes from the phrase that “filters in the inverter eliminate high-frequency components in the PWM’s output”. I thought they discard that power. But that’s apparently not the case. So the efficiency is more like >95%. So that’s good.
The issue I have with this that basically, now users need to “pay” (with compute time) to speak their mind. This would be similar than if you had to pay to vote in political elections. It favors the rich. A poor user might not be able to afford 20$ additional electricity bill a month, but a large agency (such as state sponsored, corporate agendas) might have a 1000000$.
I don’t think that would work well, because I knew no one when I came here.
Yeah, after all, we post on the internet for it to be visible by everyone, and that includes bots. If we didn’t want bots to find our content, then other humans couldn’t find them either; that’s my stance on this.
just like me!
I’ll give you a short introduction to the power grid (btw. it’s called “stromnetz” (electricity network) in german). The power grid has many “levels”, where each level represents a network of cables that transport current at a given, specific voltage. For example, you might have one 220kV level, and then a 5kV level, and a 230V end-consumer level.
Between these levels, there have to be translations. These are “transformers” today, transforming high-level AC into lower-level AC or the other way around. For AC networks, they are basically a ring of iron and a few coils. However, for DC networks, other transformers exists, such as Buck/Boost converter.
My question basically is: is there anyone who can give me experimental data on how well DC networks would work in practice? Personal experience is enough, it doesn’t have to be super-detailed reports.
All that aside yes in the future there’s probably going to be a high voltage DC network in Europe. Less so for private consumers, at least not in the foreseeable future, but to connect up large DC consumers, that is, industry, with DC power sources. If you’re smelting aluminium with solar power going via AC is just pure conversion loss.
Thank you, that was exactly what I was looking for. I know about aluminum production processes, and that it requires large amounts of DC power.
do you have a source for that?
I know about the buck/boost DC-to-DC converters, but they don’t really use AC internally.
agree
Okay, these are short term problems. “power lines as thick as your wrist” depend on the voltage. If voltage conversion works well enough, that issue disappears.
But, take note of how many DC voltages you use in your house. Devices in mine range from 3v to 25v and some weird one like 19v for a laptop.
Yeah, that’s why we need some kind of standard for these things.
well, a large part why I asked the question is because I hope that somebody knows more about what buck/boost-converters can do today. I know they work well enough on small scales, but I have no experimental data for them on larger scales.
I assume they would work well, but I’d like that somebody links me to the right datasheet or something.
Edit: you have a very important point there. " Seems like the […] voltage converter should be the prime determinant, rather than specific applications of generation/consumption." YES. So, let me rephrase my question: does anybody have experience with high-power DC voltage converters?
I don’t believe there’s misinformation because we fail to discern the truth though. Misinformation exists because people believe what they want to believe.
almost how a printing press made the production of books so much faster
… and we all know that lead to 30 years of bloody war, btw
Your comment somehow just made me realize something: When we see/read news, we have to trust the one who’s telling them to us. Since we weren’t there in person to see it with our own eyes. Therefore, it’s always about a “chain of trust”.
This is true no matter whether photos can be manipulated or not. People have been able to lie since humanity exists. Nothing has really changed. Photography, just like globalization, has only brought everything closer together, making it easier to have a more direct, straightforward relationship to other people and events. With the beginning of AI, this distance between you and an event is going to increase a bit, but the core mechanics are still similar.
I kind of wonder, how do we really know that something is true? Do atoms actually exist? What if we’re being lied to by our authorities. You say “of course not”. But what if? I mean, if we blindly trust authorities, we end up like the republicans, who believe everything that fox news tells them. How, then, do we discern truth?
How, then, do we discern truth? I guess we have to give “proof” for everything, in the sense of mathematical proof. Something that everybody can follow, using only their fundamental assumptions and deduction. I guess that is what science is all about.
I agree. Wholeheartedly. I think it’s just so obvious how quality dramatically takes off when the people creating it feel safe, sound, and economically stable. Financial Security (UBI) drives creativity probably more than anything else. It’s a huge win!
