...when they're available. Energy storage is another story, especially in places where there are no convenient hydropower facilities which can be "run in reverse" to store the output from said renewables as potential energy in the reservoirs. Maybe hydrogen storage can play a role here, maybe synthetic hydrocarbons can but for now there is no real solution for those still dark winter nights when the sun and wind are absent, necessitating the establishment of a backup power source which can cover the entire demand. Some of this can be achieved by importing power but where does that imported power come from? When it is dark here it is dark in neighbouring countries as well. There might be some wind power but that won't be enough to cover the needs. There may be hydropower available in neighbouring countries but how far can this power be exported before the losses outweigh the gains? Someone somewhere will need to build a backup power plant to cover the needs. That will most likely be a nuclear power plant since that is the only "carbon-free" source which can supply the needs. And then... there is a nuclear power plant which can supply power all day long since fuel costs are only a small part of the operational costs of nuclear power plants. Why only use it as backup power then?

A possible future scenario might be a base load infrastructure fed by reliable nuclear power plants and hydropower where possible ensuring power is always available. Renewables feeding into hydrogen storage or hydropower storage facilities to create hydrogen for those processes which can make use of it - e.g. steel production, synthetic fuel production etc. - and to keep the hydropower reservoirs filled. Domestic solar may play a role as well since it is feasible to use battery storage at a single-home scale, especially when used EV batteries start to become available at scale - for now it is just too expensive.

I’ve dreamed of having some app that mixes in bite sized learning lessons with otherwise “fun” internet (social media, news, etc.)

I could imagine it could give you a little tutorial and then ask you a quiz (to force application). If you get it wrong it keeps you at the same concept and explains it a different way next time, maybe asks if you want to revisit prereqs.

Even if you can’t memorize the answers, you can change your understanding and intuition.

No opioid addict can beat opioid addiction using alcohol. Lots of addicts end up abusing alcohol on top anyway.

And by the way, the equivalent death of an alcoholic (happens to millions of people every day) would be an agonizing death with gastrointestinal bleeding, maybe cirrhosis, maybe a long period of disability before (which effectivel can mean death if you're homeless)...

As others have already said, you pretend to understand problems which you obviously have not experienced or witnessed at close yourself.

Your "I'd rather be" sounds like "They should rather eat pie" to any person with any kind of empathy or emotional connection to addicted humans.

That being said, yeah, I'll too rather not be addicted, as addiction to hard drugs (including alcohol) means pure agony. Why does anyone "choose" agony then?

Overcoming any serious addiction is a personal, social and medical problem requiring lots resources, luck and extreme willpower.

I'd say, a form of willpower that people comparing addiction to sheer indulgence cannot even grasp.

Beating addiction is not simply a decision, although an individual decision is of course required. Seeing that as the root of the problem is a flawed view from outside that contradicts everything we know about how human brains (and lifes) work.
I'm not an economist or market prognosticator nor do I have anything to do in the financial sector besides my sagging 401k. But this is what "they" want right? A cooldown in the economy so that inflation abates. As people are losing their jobs in the tech sector and goods are more expensive, a new computer purchase seems like a luxury. This TSMC miss and Apple's sales plunge earlier is expected right? What's next? Cars? Homes?

> If you want your donation to help, at least check sites like Charity Navigator and Give Well and make a smart donation instead of blindly venmoing the Red Cross to help them fight the war against "administrative fees."

Then the title of the post should really be: "Be careful of the charities you give your money to because many have negative externalities and haven't thought through the implication of their missions very well and also waste a lot on administrative bloat". But that title won't get clicks

Probably, charities which seek to alleviate poverty are just pissing in the ocean. They can have real impacts on people but not nearly the level of utility that the federal government can provide.

But there are non-profits that do things that government simply can't or won't do, like removing landmines[1] and helping refugees escape communist countries[2]. Sometimes problems (like North Korea) are too politically sensitive for any government to want to tackle, and so it comes down to NGOs to do anything about it.

Machines cost almost nothing in China

Are you talking about the machines that can mechanize the planting of rice seedlings? I find it hard to believe that poor farmers in China can afford these machines, unless this state is providing for free, or with zero interest loans and very long repayment periods.

Also, most rice farming in China isn't done on difficult topography. I call that stereotype the "National Geographic" effect. If you look where most rice farming is done, it isn't very steep or mountainous. See more here: https://www.statista.com/statistics/242360/production-of-ric...
This is Hacker News. Over engineering things is part of our cultural heritage.
Yes, I am proposing precisely that. I understand how it might look like victim blaming, but this is not about blame. It's about agency. There will never be a culture without pressures. But everyone has the power to choose to resist those pressures. I think this is one big way that culture changes. Articles like this can also be part of it.

Consider the microwaving. I don't think there is any predatory business or institution pushing that? Wouldn't that especially suggest a bigger role for agency? Could we consider the cognitive biases that make us more receptive to flawed cultural messages, and how we can overcome them? Or is it perhaps possible that the dominant culture messages could be good in the eyes of the people sending those messages, but not good for every individual person that receives those messages?
I work at Culture Amp and was once team lead of the Design System team.

Its not hard to justify the team. If 4 front end engineers in a design system team can solve some common problems (writing components, improving accessibility of existing components, writing docs, answering technical questions etc) in a way that makes 40 product facing front end engineers more effective than 44 who don't have access to the team... then the team is a net positive.

At our scale we'd need to give a 10% improvement in efficiency to the product engineers. Both the engineers in product teams, and the various levels of leadership, have seen enough to believe we're making at least that much of a difference. Like almost any other company... measuring that accurately is a nightmare (and would require a significantly larger team just to measure ) but its a safe enough bet that we continue to invest in it.
I think it should be 0.99^10, since you lose 1% every year, just like interest.

Example showing final balance at end of each year:

Year 0: Start with $1000

Year 1: $990 (1% is $10)

Year 2: $980.1 (1% is $9.9)

...

Year 10: $904.38

For all its reputation, I'm not sure Boston is clearly a lot harder to drive in generally than a lot of San Francisco is--given Boston weather for maybe 8 months out of the year. However, after a big snowstorm (admittedly not much this year) it's a whole other game. And while it's easy to say just don't use self-driving if there's a snowstorm or if lanes are partially blocked by snow, that's not ultimately a driving system that can be depended on. And I guarantee people who maybe only drive a few dozen times a year in the worst conditions will be an absolute menace on the roads.

(And "just don't drive then" isn't an option for a lot of people in a lot of circumstances.)

Leaks are common with quick-install couplings and shoddy soldering. They seem to be more prevalent in the US, because qualification requirements for the installation of A/C and heatpumps are low to nonexistent, and anyone can just visit the DIY store and get refrigerant refills. So a leak isn't much of a problem beyond getting a cheap refill for most people, so craftsmen don't prioritize leakproofness.
The wikipedia page isn't as detailed as I recall. I don't think that physiological disease can totally explain the phenomenon. The building of stages and congregating of dancers together, to me, suggests there was another dimension to the phenomenon.

You cannot talk about the homeless as some monolithic group of people that are all the same. Some of them are schizophrenic and their nature is crime because their brain is haywire. Some of them are addicts (both legal and illegal) who would be nice people if given treatment for their problem. Some are at nice people, but they are at the bottom of the intelligence chart (not to be confused with IQ, but instead what people think of as intelligence despite it not being well defined) and mentally unable to hold a job that could support themselves. There is a lot more, but I'm not a homeless expert. The above are just specific people I know (either family or family of close friends).

Some homeless are also criminals, some are not. Some of the criminals would turn away from crime if given the proper help, some will not. Some of them will refuse help unless it is forced on them - we have as a society rejected the needed force because of rampant abuse in the past. Each situation is different. Some of them are easy to solve - most are not.
Specifically, what the heat pump dryer is doing is basically pulling air through the clothing which evaporates some water from the clothes into the air, then cooling the air, which causes water to condense, removing the condensed water and warming the air back up to send through the clothes again. The effect is much closer to the clothes hanging from a line in a garden on a perfect drying day, except it's inside a box.

Whereas the other way to do this is just cook the clothes and the water evaporates, then you dump the warm moist air either outside or into a separate dehumidifier which throws much of the energy away. As you observed this is faster, but most people don't need faster if it's unattended. My dishwasher is slower than washing dishes by hand, but I don't need to sit there watching while it does it so who cares?

> This ensures you can never really retire and you have to continue to work no matter what.

Norway has a state pension and isn’t especially notable for late retirement (modulo life expectancy). One usually also invests one’s savings which rather mitigates the effect of the tax and inflation.
I am an Apple ][ fan. I started off with some big iron, then discovered the ][ and rarely looked back. I dabbled with the TRS80, VIC-20, & the C64s but I came back to the ][.

Apple started as open as one can expect at the time. The system was readily modifiable in all kinds of ways. I was able to build my first modem card without voiding warranty or breaking the system.

The arrival of Mac was the end of that era. A new, locked down, fully-out-of-my-control environment emerged. No more easy modifications. I am not disparaging the Mac, I derogate the lack of openness.
This isn't a strong argument for externalities: no municipality in the world would (should?) accept toxic waste being dumped in its water supply just because a small fraction of its tax base is paid handsomely to do so.

Put another way: the value proposition for SF (and other tech cities) exists above and prior to these companies being allowed to treat the city's streets as a testing ground.

Complete denial of reality. I've posted actual numbers on real costs, but of course there are always people like you dealing with imaginary money, throwing around numbers they can't back up.

Pessimistic 5 billion per plant -- what a joke. Flamanville 20 years under construction, 20 billion. Olkiluoto 15 years under construction, 15 billion. Hinkley C, deadline for 2027 already clear will not be held, price tag already estimated now to be 40 billion in the end [1].

If Germany had done what France had done in the 70s and 80s it would be in the same situation as France is today: every other month a plant goes into emergency maintenance because of cracks in the pipes, and relying on neighbors to keep its lights on.

If it had invested in nuclear 20 years ago it would be sitting on heaps of unfinished uneconomical plants and it would still use coal for the majority of its electricity. The plants even if finished would take decades to make up for the lost opportunity to reduce emissions during the decades of construction.

Rubbish! Nuclear energy's days are numbered. That industry will need to find another way to take tax payers' money.

> Are bike manufacturers going to pay for bike lanes? Or is it going to be a regressive transfer?

The fact that there are less cars on the road already is a HUGE benefit to them. Less cars => less parking lots and less noise pollution => less maintenance costs => savings for tax payers.
Few reasons:

- nothing public should be closed source, just think about electronic IDs, most of them here in EU are ISO 14443 smart cards BUT with proprietary middlewires, what if a day one of their OEMs cease to exists and so no one else support it's middlewires?

- infra can't be designed up-front well, countless of integrations might be needed, it's not just a matter of open protocols, for instance a State might develop an SSO for the public sector, anyone can run an instance of a federated services and integrate it in their own infra stack
Yeah, VisiCalc + Apple ][ was the real revolution. It gave non-hobbyists a reason to buy a computer. VisiCalc sold Apple ][s and pushed most of the Apple ][s into businesses which surprised the Steves quite a bit. The next big moment for microcomputers was really the internet. There other things, but spreadsheets continued to be a big reason for computer sales until the net.

I have two self-installed ground source heatpump units (6 tons total) in operation since summer of 2016 with no maintenance except for the loop pump. I was using two very old second-hand pumps until last summer (one for each unit), when one impeller completely disintegrated. I took the opportunity to reconfigure the plumbing and wiring a little bit to use only one pump (more modern, theoretically better fit for my system), and it has been smooth sailing since then. We'll see how long the new pump lasts I guess.

As for loop installation, I have a few acres and dug a ditch with my dad's backhoe. Most homes around here don't even have room for a septic system, much less a horizontal ground loop. I can't speak to the cost of a vertical system, but I think it would also affect the specs of the loop pump, and not in a good way. Check for tax-incentives as well: I got a 40% tax credit on the units themselves when I bought them.

I have to edit to address the underground refrigerant leak:
I haven't had to deal with this. I can only say that it would not be a fun time. I think in a properly installed and tested system, it shouldn't really happen outside of freak seismic events though, at least within a human lifetime.

False, everyone is not a Pedestrian, I moved into my current home specifically because there are no sidewalks (and no HOA), and I resist any movement to add them to my street.

People that want to use and benefit from Self Driving cars, just like people that vote for sidewalks.

I have a feeling the number of people that want the dream of being able to have a car that just drives itself is FAR FAR FAR FAR higher than the number of people that utilize sidewalks. At least for my Geographic region...

The article cites how they've struck deals with the grid operators. So therefore they're just using grid energy and hence using the carbon intensity of the local grid is very reasonable.
The huge amount of cars makes it seem attractive to widen roads and such. Which, more road surface leads to more maintenance. Along with that, widening also induces more demand and such.

I am sympathetic but I suppose I am one of the person's you describe here. I do not want homeless in my street. I actually don't mind someone sleeping but unfortuantely if you are homeless, lying down isn't the only thing you do on the street. And if it's allowed, how many homeless people are you ok with on your street. I suppose with homeless people on the street, you can anything from just a person keeping to himself to mental health issues to drug use to crime. Now would I want that where my kids play/walk etc. I'll be honest, I do not.
Now let me talk about property values too. I worked hard and saved up for x years and bought a house in a good neighborhood (location, location, location as they say), took up a 30 year loan. Now, if the property values drop because there's a homeless camp in the street, then I am under water for a long time, potentially even losing my house. My home, which was also me building wealth for myself when I get old, will also loose value now. If you suddenly take away value from my biggest and long term investment that took years of work, yes, I would not want that either.

I understand the problem and I will support solutions, but just saying let people live on the street in front of my house is simply not one of them.

I have a 12,000 sqft building in the northwest corner of Massachusetts. Really well insulated and heated entirely with heat pumps. I have a large solar array to offset the costs. I ending up paying around $1.50 this year for all the electricity. If I factor in my SRECs sales it drops to around $.75. Last august the Governor signed new legislation that increased the the price utilities pay for the KWhs I produce so I expect another reduction in cost. The biggest problem I have is that 5 years ago all the HVAC installers claimed one couldn't use a heat pump in our area. Now we need many more installers than are available. Our local vocational school just added an HVAC heat pump program for the build back better funds.
Other follow up, you can always buy government treasuries for yield to offset the tax, which requires very minimal work. At billionaire wealth level, you most certainly have someone managing the funds for you.
I have a pretty high efficiency tankless boiler so it would be expensive and wasteful to switch at this point. It is possible to buy a wood fired boiler and hook it up to the house to supplement the tankless but I'm skeptical that makes financial sense.
