Hydrogen is in an economic race with batteries in storage. Hydrogen is hard to store in tanks and has a higher thermodynamic loss and the fuel cells are expensive. Batteries are big and expensive.

So the efficiency of hydrogen split-store-generate needs to beat the efficiency of store-release of the battery and the costs of the equipment.
This depends on the compiler of course. Most will not because it is not worth it, but I expect that there is at least one compiler out there with the option to exhaustively search the allocation space for that very last nanosecond of runtime optimization. Probably inside an HFT firm somewhere.
I often find that developers jump for threads too early. Concurrency is much easier to reason about than parallelism.
it looks like this linter is _specifically_ for try/except linting. do you anticipate users will use this alongside another linter? or do you plan to grow into a full linter?
That's wonderful, but be careful generalizing your experience to others. You don't know who is struggling with mental illness, executive control issues, ADHD, OCD, depression, etc.

Tobacco is more than nicotine delivery. It contains harmaline alkaloids, which among other effects, is a monoamine oxidase inhibitor. Quitting a cocktail of nicotine and MAOIs, while those stimulants are "treating" underlying conditions, is a way harder task.

For these folks, vaping is absolutely a step up, and allows them to wean off the tobacco MAOIs, especially in conjunction with treatment such as bupropion.
Most nations won't bother lowering their emissions. So the question is not whether CCS is cheaper than not emitting, the question is whether CCS is cheaper than taking action to force the issue. Which would include abandoning several international treaties like the WTO, air traffic agreements, maybe impose sanctions and even go to war.

If climate change is a sufficiently important issue, then hell yes, the US should be paying for CCS, even if that means that the Saudi royal family can afford a few more solid-gold-airplanes. If the issue isn't that important, than why bother at all?
Have you ever heard that "posession is nine-tenths of the law"? Well... this is a system in which "posession is ten-tenths of the law".

This has obvious disadvantages (as you pointed out), but it also has a clear advantage: it becomes trivial to figure out who effectively owns something within the system (whoever controls/posesses the associated key).

Just because a system doesn't encode/enforce "property laws", doesn't necessarily mean that it is useless. In fact, few systems (if any) formally encode property laws: that is always something imposed from the outside.

If someone steals your crypto keys, you can still use the (normal) court system to get your assets back (assuming you have some way of proving that you own the assets, and you know who stole them from you).

Does the Internet encode/enforce property laws? No. If someone (e.g.) copies your stuff, you're still forced to go to the court system (just like when someone "steals" crypto from you). Does that make the Internet "not suitable for almost anything", just because it doesn't automatically enforce property laws?
He does have a point in that a 12 MP CMOS sensor will have 12 million sensor elements, not 36 million. Colour filters are placed in front of each pixel, so RGB data can be extracted. Usually, 1/4 of the pixels are R, 1/4 are B and 1/2 are G. The raw sensor data for each pixel thus contains either R, G, or B, of varying intensities, depending on the passbands of each filter. The data is combined using a demosaicing/debayering filter/algorithm to extract subpixel data. That is, surrounding colour information is combined so that each pixel has R, G, and B elements.

Sorry if the writeup isn't that specific, I mostly work with monochrome CMOS cameras.

https://en.wikipedia.org/wiki/Demosaicing
https://en.wikipedia.org/wiki/Bayer_filter

edit: I should also state that I don't know anything about iPhone cameras. It's quite possible, but not typical that they have a 36 MP sensor producing 12 MP images.

edit 2: I read that the iphone 12 has 1.7 um pixels. A 36 MP 4:3 sensor with 1.7 um pixels would be 8.3 mm. A 12 MP 4:3 sensor would be just 6.8 mm wide.
Pointing out inaccuracies isn't "arguing against climate change" or at least it doesn't have to be.
I think banning it is the wrong approach. Data ownership should be regulated that personal info belongs to the person it is about. Companies need to pay for it if they want to store it over a certain time period. They also have to face large fines when they leak personal info.

Imagine how quickly companies would only save minimal personalized data.
Yeah, you're right that it's not a perfect analogy, but I think mine is closer to reality than OP's... There are plenty of apps (stores, in the analogy) out there that are actually designed to work on many platforms (with many cars, in the analogy), but still have to pay the store %.

The broader point is that just saying "oh, it's like X, therefore we should treat it like X!" just isn't enough for app stores. There is no perfect analogue. Apple and Google call them "stores" because they really want them to be thought of that way, but there are important features of phyiscal stores that the app stores lack, and important features of app stores that physical stores lack.

How we, as a nation and a society, decide to treat app stores for purposes of consumer protection laws is up to us... so let's be careful just blindly trusting the way these companies want us to think about them.

What I don't understand is people who deny climate history. Facts are facts.
I find this movement very similar to Buddhism or Christianity teaching, in the sense that you give up material world as the circumstances are such that you can not win.
If you perceive world where every man mad political system as practical implementation is aristocracy then understanding that there is no democracy, socialism, communism (as they are just a flavor of the same system) will lead you that there is split on two group of people those who are aristocrats and those who are slaves.
Only difference is that "good" aristocracies give more rights and more resources to their slaves. So, as each aristocracy must have slaves to exist (which will turn at some point to robots and AI) they have to advertise production of more slaves.
In that regard in Buddhism and teaching of Christ to escape vicious cycle of you or your children being wolfs or sheep, only way to escape is to exercise nonviolent resistance and give up on the entire game.
I'm surprised no one made conversation about the same with covid testing and potential DNA harvesting too.
> And rich people tend to pollute more, so it will make poor people better off.

In the long term, poor people will be better off, yes, but not in the short term.

I'm not convinced. Carbon improves the living standard of everybody. Even a fair and progressive carbon tax will hit poor people harder in relative terms. So even if it hits rich people harder, it will much unpleasant on poor people than it will be on poor people.

To give an example, removing 5% of the income of poor people is much more unpleasant that removing 30% of the income of rich people, for plenty of reasons that are explained in studies on inequality.

So I don't disagree that rich people pollute more and will be taxed a lot, but it doesn't change the fact that poor people having been benefitting from CO2 emissions, so the 30% of rich people, as individuals and not corporations, are not responsible for the majority of CO2 emissions.

Cutting the emissions of corporations will also affect poor people in unpleasant ways.

This forum is rate-limiting my posts so I am not able to respond to each particular thread.

I am guessing that the renewed interest in our game is coming from the recent post at Astral Codex Ten: https://astralcodexten.substack.com/p/lockdown-effectiveness... It is well worth reading that post.

Let me also link a post from one of our collaborators explaining how, for most countries, the dichotomy between saving lives and economy was somewhat false and relative to the real outcomes it was possible to improve both: https://translate.google.com/translate?sl=auto&tl=en&u=https...

A lot of the discussion on this forum center around the question what was the optimal policy and how well the game simulated that policy. In particular, there is a lot of discussion around the two "extreme" approaches: "zero covid" and "no interventions". That is fine, we had these discussions many times and we can explain how these approaches are represented in the game (in my opinion, not too unrealistically) but, at the same time, it somewhat misses the point. The game was about building intuition about simple epidemiological SEIR model close to the regime where the real country was operating - and for political reasons it was very unlikely that the country will radically change the course.

Lot of the game design decisions were some compromise between different goals of the game. Let me give an example: the team of authors of the game strongly believes that expanding contract tracing would a good thing. We were considering adding it to the game. However, what would be a point of adding that option to the game? It would further clutter UI (we had mobile users on mind). It would not add anything to the game because the decision to expand tracing would have no significant downside. And last it would hardly add anything to the public debate, it would just communicate that the authors of the game like contact tracing. There were already zillion of well argued opinion pieces on the topic. In fact, failures of contact tracing were more about failures of the specific agency than any conscious decision on the decision maker side. In short, tacking this issue in the game would quickly move from mathematical modeling into much more murky waters of public service efficiency.

You should also keep in mind that the game was just a small piece in a bigger mosaic of truly incredible efforts of many other volunteers. E.g. "Interdisplinary group for epidemic situations" https://www.meses.cz/. The game was never intended to provide comprehensive picture or recommendations.

The 1936 records were lower. They were in a different region with different climate. And human activity was part of why they happened.
Yes, you can use any existing python modules. In the demo you'll see I am using pandas dataframes in individual cells. Pandas is built on numpy.
As a developer who uses Rust a bunch (work & personal), this is what I ended up having to do. I'm joking, but this one simple trick can cut compile times in half.
Yes, and it's richer for it. Java is definitely not the last word in language design!

For the last 30 years, parents whose first child was a girl were allowed to have a second child (not everywhere, but this was still for many hundreds of millions of people).

That's actually more than enough to explain the skewed ratio, even though selective abortions likely also have had a noticeable impact.
Did you read even one of the articles I linked?

But the BBC article... "the research has not yet been peer-reviewed.

"They used 21 climate models to estimate..."

"They compared the climate as it is today, with the world as it would be without human-induced warming."

This is not empirical science. And by using a 1000 year model they are starting their analysis, conveniently, after the peak of the Roman Warm Period.
The best strategy is to place environment at the top priority, to breakdown capitalism and the frenesy for consumption, money, products. It's not idealism/utopism, I've been living since 10 years somewhat far from the modern lifestyle (except my laptop), I use a bike, and eat local fruits and legumes, or markets vegetables left/wasted at the end, I go to supermarket once or twice a year to buy soap bars and rice/quinoa, that's all. This guy is also a good inspiration https://www.robgreenfield.org/. It takes time, but it's easy to do the switch, governments/countries need to stop behaving like financial companies, we need to have public fruit trees and on the other side reduce the useless services and jobs (luxury, tourism, ..), remove intermediates, promote local food (avoid industrial collecting non-ripe fruits, and wasting ripe ones, ..), so many simple, logical things. Just reducing the use of cars will make people change their lifestyle for the better (both them and environment)

That is I think the solution, not a rocket science solution that tries to find yet another industrial way to depollute one of pollutants (and probably worsen the case for others and the overall balance), just a natural solution. As soon as people have a environment footprint much lower, like mine, it's like the total population is divided by 2 or more
Yes, but currently, attribution is hard. And the press cried "wolf!" far too often with each and every lightning storm that was a little more severe than average. So currently there is no credibility in that future cost projections.
>> massive, expensive, and hugely uncomfortable changes in one's lifestyle.

Why? The biggest climate change issue, carbon, doesn't require any lifestyle changes. Solar/wind/batteries + nuclear reactors can provide us with all the electricity we need. Cars/trucks can be electrified in the near term too, although there are non-electric green options too (fuel from captured carbon).

Maybe if your precious "lifestyle" involves rolling coal as you drive to you private jet to then go shoot some endangered lions. Maybe if your lifestyle involves a love of smokestacks or indulging a hypochondriac fear of that windmills will give you cancer. Those people will see an impact. But us normals can still drive cars and have air conditioning in our apartments.
There's a real argument to be made there at the level of federal policy, but note that the US is at or near the top of the list in per-capita wind/solar/hydro and that it dominates world battery vehicle technology and production (though not yet deployment domestically).

There's a real schizophrenia problem politicly, and it's worth discussing. But really, americans are your allies here, and the US is doing a ton more help than harm.
Cigarette smoking is so harmful, in addition to the reasons cited by other comments, because you are inhaling burnt matter. Vaping doesn't involve this.

Big difference between inhaling a heated liquid vs combusted solid. And yes the nicotine is mostly harmless. I rather enjoy my nic addiction with good black coffee.

"Costs money" is not an argument that is of much use - for an economy. Cost is income. It's a circle. Only when you apply the mindset of an individual does that cost avoidance mindset make sense. Then "costs" represent something really gone and lost. On a bigger scale though, if you want more income for more people you don't want to reduce "costs", quite the opposite.

The question for an economy is, does the flow of money lead to outcomes we want? I'd say if it flows through paths that lead to the growth of businesses that are good to reduce climate change impact that is something we want. On the other hand, if it flows through paths that lead to growth of purely financial constructs, wealth concentration (which also concentrates control, quite the opposite of the mantra of capitalism which is supposed to be freedom to do your own thing), or more unwanted telephone calls, or overpriced medicine, that's something where we would want to redirect some of the flow. For an economy, money is more about the flow, like blood. Where it passes things grow. So we want to look at the paths of the flows. "Cost" is of little use here. Of course, if you have a concrete thing you are looking at and want it to be more efficient cost again makes sense, but in this discussion here we are trying to make different kinds of decisions, where "cost" is less helpful, since we don't even have anything concrete that we want to make more efficient.

DISCLAIMER - These are the thoughts of someone not trained in (apart from a few semesters on the side while studying something technical) or working anything related to economics.

> For the very wealthy it’s simple greed.

It's greed for basically anyone above the poverty line. There's functionally no difference for wanting a better life for you and your children and to increase your wealth for what is, in the end, the same goal.

Unnecessarily driving an SUV, eating far too much meat and running the lines supplying peoples with those meat is morally not that different.
He goes over some fun and inspirational stories about that yes. But it's much more than that:

"In a lot of people's minds power over others equates to money and profits. Hey, is it your computer, or is it some companies' computer?"

He talks about companies trying to control and inhibiting repair and modification and compares it to the liberating and creative experience that he had and how that lead to him building the apple. He also compares the situation to a previous phone monopoly and how standardization and freedom lead to innovation.

The message is really strong and important and goes beyond what I assumed is going on with this movement. The Right to Repair isn't just about being able to fix things yourself. It is about fundamental freedoms that enable creativity, innovation and efficiency.

Looks like I need to move to a cooler area. Is there anywhere that has maps with projected yearly temperatures in different regions of the US? For example right now Boston is miserable in the winter, but it'd be nice to see projections or at least a historical trend of what the average monthly temperatures would look like 5-10 years from now. If they looked better then I'd look to moving up there. If they're too cold maybe I find somewhere more south like New Jersey, or if too warm somewhere more north like Maine.
Most people think we understand gravity better than we actually do.

To compare it to an actual hot-button issue, we know more about the mechanisms of evolution than we do about the mechanisms of gravity.

We know kind of how it behaves at various scales, but we don't know why it does. We don't know what makes gravity. Why do denser objects have more of it. Why is it weaker than other forces, yet felt on larger scales? Does it actually exist or is it an emergent property kind of like the centripetal force (or is it centrifugal, I keep getting those flopped)?
I always assumed carbon capture was a hard requirement for a sustainable future, as long as there are some things that can't be run off of renewables.

Plus, even if the world dropped its co2 output to pre-industrial revolution levels, wouldn't we still have to capture carbon to reverse the damage already done? Or is there some natural process which will slowly bring co2 levels back to some equilibrium level?
Yeah, can really see that "empowering everyone" motto coming into play.

I don’t understand why the intellectual narrative is “CO2 reduction at ANY cost… as long as we’re not wasting money on those expensive nuclear power plants”
> Of course, instantly sending all (or most) of Earth hydrogen into outer space is impossible — at the current technology level. But wasting what little water we have to make it is still a bad idea.

The whole point of making hydrogen (from water) to store energy is so we can release the energy later — by oxidising it back into water. We get the same amount of water back afterwards. No one is going to be stealing water to make hydrogen.
Copyrights and trademarks are entirely different types of IP.

...therefore it's possible to infringe THE TRADEMARK with a counterfeit product.

There is no such thing as counterfeiting the open source design.

EDIT: I'll add examples, it might help with the downvotes I'm getting:

- an OEM can make exact copies of a truly OH board but sell it under a different name and brand. Trademark is safe and Open Source is working as intended.

- another OEM can make its own Arduino clone with a different PCB layout and slap the Arduino logo and name on it. Trademark is breached and openness is lost and this is already happening.
