Everything else apart from solar is generating AC. You'd need expensive converters and more expensive switching equipment with arc supression in order to transport DC. HVDC is mainly used for underwater cables because it's more efficient to transport DC than AC by cable. We'd probably benefit by interconnecting these cables coming from offshore wind farms and imports with parallel land based HVDC infrastucture.

Oh, come on. Most houseowners aren't landlords (people who own multiple properties and make money by renting it to others).

It is in the interests of landlords that as few people owned property as possible. This being pro-landlord is being anti-ownership, numbers-wise.

I'm pro-owernship of property, I'm anti-getting-rich-off-mere-ownership (that is, quite literally, rent seeking).

Someone who only wants the police to have easy access to guns is anti-gun ownership.

Someone who only wants landlords to own property is anti-property-ownership.

And being pro-landlord is exactly that.

TL;DR: all landlords are owners, most owners aren't landlords. And the rent is too damn high.
This might be off topic but I just don't know what else to do. I don't understand why we're not in full-on panic mode yet. It makes me scared. Really scared. As in I've never been so scared in my life.

We knew about climate change for decades. Scientists keep producing report after report after report. Every one grimmer then the preceding. Yet the global GHG emissions just keep going up. Governments and politicians have failed to act. I am tired of waiting for systemic change. I am tired of waiting for technological breakthrough.

While we should keep fighting for systemic change, I begin to believe individual action is paramount and a prerequisite for any broader change to take place. The time for signing petitions is over. It's time to act. There are no low-hanging fruits here. There will be no silver bullet. There will be lots and lots of tweaks across the board.

People don't like being told what to do. I get that. But I am not a politician telling you what to do. I am your peer crying for help. Please do something. Please don't say "most people" wan't sacrifice this or that. I am not talking to most people. I am addressing you, the HN crowd.

So what an honorable member of the HN community can do

- Stop flying to conferences. Go to a local meetup. It's fun. And cheaper. If you really need to get out of town, take a train. Don't think about it as not flying for the rest of your life. Rather, can we declare a moratorium on conferences for like three years? Let's hope by then Prometheus will give us carbon-neutral jet fuel

What I don't understand is why this is so controversial. I clicked on a link in the article, leading to this article: https://techcrunch.com/2019/05/06/new-study-shows-human-deve.... The comment on it is extremely dismissive about climate change. I see this on pretty much every news website nowadays. First of all I don't see how man-made climate change is even controversial with the amount of evidence we have, but furthermore I don't see why we shouldn't transition to renewable energy asap anyway. Even if climate change would be a hoax (which it is not), then why would it be a bad thing to make changes to prevent it from happening anyway? Why would it be a bad thing to get rid of air pollution? Why would it be a bad thing to switch to an energy source that doesn't run out in ~20 years simply because it isn't renewable?

It's strange to see the concerns they had then (image manipulation) being echoed today with video and the dangers of deep fakes (and related audio with lip synchronisation).

With some perspective, it may looks like that concern about fake images has not really become a huge concern for society and people still get caught when they try to pass some fake as real (witness the recent roar about Nat Geo's night sky pictures[1]).

The impact is maybe more subtle though, with some going to the extreme of doubting photographic evidence as being fake even when it's not (moon landing deniers, flat earthers, ...).

Technology at least introduces the potential for creating doubt in people's mind: a way to manipulate people's emotions and opinions either by creating fakes or rejecting real images as being fake.

Riot/iOS is already native, and works pretty well, so will likely evolve to behave more like RiotX as time goes on rather than getting rewritten.

RiotX is trying to be something that starts off feeling like WhatsApp or Telegram, but can expand into IRC/Discord/Slack for powerusers. Who knows if it'll work.

For native desktop apps, there are a bunch of other Matrix clients focused specifically on that domain - e.g. https://neilalexander.dev/seaglass and https://wiki.gnome.org/Apps/Fractal and https://github.com/Nheko-Reborn/nheko and https://github.com/QMatrixClient/Quaternion. Riot/iOS might expand into Riot/macOS though in future (although this is basically what Seaglass is already).
You know why. Most of the world has market economies that rely on growth. The measure of growth is GDP and put simply GDP doesn't measure how much you're wasting, just how productive you are. Short term political aims are in conflict with long term environmental stewardship. The current US president only cares about his numbers, not the mess he's leaving behind. We'll be in full panic mode when it negatively impacts GDP, which will of course be too late.

This is written by someone who doesn't know what Core Data is, or how it persists its objects. It's funny to see how they try to guess what various columns are and how data is formatted.

Story of a script deleting my developer account
There is a theory that what we consider ADHD might have naturally evolved, because it would give an evolutionary advantage for hunter-gatherers.[0] Life in the modern era is different from hunter-gatherer lifestyle and thus people with ADHD find it difficult to fit in.

I don't know how true this theory is. There is some evidence for it, because ADHD is very prevalent, but at the end of the day it doesn't matter why people struggle. What matters is that they do and we have the tools to help with that.

A big reason for the divide between Europe and the US in ADHD is that Europe usually uses the ICD, while the US uses the DSM. The DSM seems to be less strict about the criteria. It's probably also the case that many Europeans, particularly in former Soviet states were never tested.

These services of course provide some value: they are easy to find/stumble on, they free customers of excessive choice, allowing them to not be actively interested in art and collapsing everything to simple "choose your style" option, they free customers of direct communications with artists, they arbitrage prices between different geographical markets.

On the other hand, these services compete with traditional artists, they devalue regular artworks in the minds of common potential customers AND further reinforce the thinning of the line between art and prints one buys in a furniture store.
Only about 25,000 years ago (into the last ice age), atmospheric CO2 levels were at 180 ppm. That was the LOWEST LEVEL in the entire 4.7 billion year history of earth. This is something that the ice worshipping fanatics of today will not tell you.

At 150 ppm, the enyzyme RuBisCo, existing in all photosynthetic organisms, basically stops functioning. At this point, all photosynthetic life dies off, followed by all other life given the food chain. It would be earth's greatest extinction event.

Thank humanity for putting some CO2 back into the atmosphere and averting a global catastrophe. At 415 ppm, it's a small fraction of the highest levels reached in earth's history, at 8000 ppm.

The problem is that most of the ideas you propose - although good - only have force in the West.

Western countries are not the major culprit at the moment. EU has decreased their CO2 emissions by 20% during the last 30 years. USA has maintained them. China and India, increased them by 300% and China alone now emits more CO2 than USA, EU and Canada combined.

This is not to say that Western countries can just cross their arms and do nothing, but, they are not the ones that are going to change the picture and all this discourse about global warming has been turned in an anti-West political weapon that never addresses the real issues and never has the courage to point their finger at the countries that are the biggest problem at the moment.

This way, I fear no real change will happen until it's too late.
Hi! Thanks for the elaborate reply. It's actually for a different idea that I am playing around with and am just trying to see if I can find people to talk to to get a lay of the land and or throw a landing page in front of them.

Reasons you should buy a hybrid bicycles
Or maybe it's not as bad as you think?

Like the fact you think the reports have gotten more and more dire is debatable at best, there were many reports decades earlier that predicted that today we should have already experienced at least a foot of sea level rise.

Also if you were concerned this was a life or death situation, why didn't you mention global birth control as an option? At some point you have to admit that humans aren't going to be net carbon neutral unless we come up with some great new technology that just solves the carbon crisis.

If we assume the reality of this, it only stands to reason that a booming population will lead to more carbon pollution and so the flip side also stands that a shrinking population will reduce carbon pollution.

I'm just saying that I find the bleak view of the future where we all just stop flying planes, turn off our computers and live in our little communities. We have to accept that we are a global community and breaking that down isn't going to solve the problem of carbon pollution.

Please do get involved with Green New Deal activism. Personal responsibility is great but it will NOT fix the problem. We need fundamental changes in how our global economy operates. We are having a moment in politics where it seems real change is possible, so please don’t let the slow progress of past years get you down.

I upvoted you, all the 3 suggestions are very good. However, I don't think individual action is going to cut it, I think the government needs to start explaining the problem and coordinating change (especially in private companies), and that's why you need petitions. It needs to be on people's minds, so that they can support each other in doing all these things that you have suggested and more.
That accounts for some portion of it, for sure.

Hi!

Thanks for sharing. Yeah I totally get you. Have been very dependent on Google with another project of mine and it's not great. But right now I am more trying to figure out how to just get a bunch of (target) people in front of my MVP (which is really just a landing page) for another idea, just so I can start to talk to them.

I feel a landing page is probably not enough to post on HN or PH but paying Google for ads is also so, so. The other thing I have been trying is going to related subreddits and that seem to bring in at least some feedback (maybe not super specific to what I am doing, but in general).
As others have pointed out, most issues are political, not technical. There are already places which would be perfect(deep mine shafts surrounded by salt deposits, so they are literally impenetrable as salt is self-sealing) but the countries/states they are in object to keeping the waste as some sort of ideological issue.

What I want to know is whether there is a technical issue with what I am suggesting.
