Most comments are missing the point of Direct Air Capture (at least the point the people working on this are making): In no economic way can DAC compete with not putting CO2 in the atmosphere in the first place. It is vital that we do our very best to first reduce and then eliminate our emissions. But even with this very best, there is still going to be lots of CO2 we've blasted into the atmosphere on the way to zero emissions that we will want to get back. And sure hundreds of dollars per ton of CO2 is extremely expensive, but by then removing it out of the air is our only option, and it is (probably - if the economy of scale works out) still cheaper than the damage climate change inflicts. Still, why do DAC now, when there currently are better options available (preventing emissions)? The reason is that we need to give those economics of scale a chance, and the prices can't come down without incremental improvements and real world experiments that will take some time.

There is a bigger problem. Those who scrutinize climate change are punished by the society even though we need legit scientists and people that debunk overarching claims. You could accept CC arguments but still be a critic of some of the insane claims going on today.

It's like the early COVID days. Can't criticize. Can't speak against the mob. Can't do science without scrutiny.

The whole article seems to be about sticky sessions which are needed for the long polling fallback transport option Socket.io uses when websockets can't be used.

Eg. from the article:
"
the WebSocket transport does not have this limitation, since it relies on a single TCP connection for the whole session. Which means that if you disable the HTTP long-polling transport (which is a perfectly valid choice in 2021), you won't need sticky sessions

>> Why can't I tell that my turn signal is on by 'feel'?

I once had a ford rental car with turn signals that made me actively avoid using them. They felt OK, but the clicking of the relay was fake, a recorded sound. All seemed good until you cancelled the indicator. The computer sometimes kept playing the fake clicking sound. It kept clicking for a full click cycle every time you cancelled the indicator mid-click. It was only a fraction of a second, a full second at most, but I always thought that I had failed to cancel the indicator. It was both the smallest and most annoying problem I've ever had with a car.

2nd most annoying: Driving a US-made care in a country using the metric system. The cruise control is incapable of being adjusted a single kph, instead the minimum change is some number of mph. So you are stuck doing either 99 or 101, but never exactly 100 kph. The source of the problem is confirmed where the cruise control can be set to 80 kph, which is almost exactly 50mph. I venture that no BMW has ever had this problem.
> But this time really is different. Driven by war and pandemic, a new macroeconomic paradigm is forming. High inflation is back after a 30-year absence, and with it, much tighter monetary policy. Interest rates are rising, and central banks around the world are burning money. The era of plentiful dollars is coming to an end. And that will mean persistently lower prices for cryptocurrencies.

This seems to be the gist of the author's case. What the piece fails to consider is the possibility that "much tighter monetary policy" is transitory. Really, the author goes on as if we're 800 basis points into the Fed hiking cycle when it's just barely lifted off. And QT, although it is supposed to have started, has done very, very little to turn the Fed's balance sheet around. Those MBS are still safely in the lockbox.

How exactly does this author think the Fed will react to another housing market crash? One that stretches out to an election year? One like 2008 that permeates the entire economy?

It's gonna be bazookas and "whatever it takes" as far as the eye can see. It won't matter what the CPI is reading.
> How many people have been killed in US wars

Easily in the millions. And that’s innocent civilians, not combatants. Not to diminish the suffering that happened there under Mao - but the lives ruined by US wars continue to add up. People are still born to this day with birth defects and cancer due to the chemical weapons we used in Vietnam, for example. And if we’re counting the 20th century, how about the fact that Hitler was inspired by America’s treatment of Native and Black people when he started the Holocaust? Eugenics got its start in the US. Genocidal forced sterilization of minorities was still happening here well into the 20th century. The list of atrocities goes on.

> Remind me where the US has implemented a concentration camp of about a million individuals based on ethnicity alone

Native Americans for the entire history of our country, until we finally put them on land that white settlers didn’t want. Japanese during WW2. Prison/torture camps all over the world during the “war on terror” which scooped up Muslims indiscriminately under the guise of fighting terror. These were all either officially denied, or admitted and openly justified at the time.

And forget corporate espionage - how about the well-known fact that US intelligence agencies have outright overthrown and assassinated democratically elected leaders all over the world? We even did it to Australia, an ostensible ally.

I’ll give you that China has a horrible record of harassing and imprisoning people who criticize their government, as well as censoring media. That’s one thing the US has going for it.

But as far as democracy goes, the things we’re talking about here - data collection, spying, extralegal evil acts committed by governments in secret - aren’t things that we get to vote on in America. Not one of us idiots arguing online has any say in what data the NSA collects and how they use it. Neither does any elected representative even bother talking about that anymore. Most of them don’t know what the NSA does, either. Them and the CIA are entirely unaccountable to democracy and that’s by design. It’s marginally better because we can at least talk about it, but that’s only because we’re powerless to stop it, so our opinion really doesn’t matter.
For context, here's a news article from March of this year:

You need to think bigger. There are several ways. Eating all the remaining individuals in a local population of an endangered animal until splitting the species in two isolated areas unable to survive, would be the obvious one.

> Despite this, what one could consider natural French territory, Belgium and Netherland

What's natural about this? Those countries had been fendong off occupyers for centuries by the time the French made any serious progress during Napoleon. If you're refering to the Rhine/Maas delta, after the Roman empire it never was a (significant) border again, at least not in the Netherlands.

This is actually quite common in the hardware space. A hardware project can take a couple years, meanwhile the existing product has to be sustained. Also, a lot of stuff in a hardware product can become a total loss due to component obsolescence or the need to cram new / different features into a physical footprint. Even if it was a great design.

As others have pointed out, just like in software, we have to be cognizant of the career risk of hitching one's wagon to the product that's going out the door.
I work in the carbon removal industry, and your calculations add up.

Where I encourage you to explore is what an equivalent unit of energy spent on developing new carbon removal systems is right now vs the equivalent unit of energy spent to make another solar panel. There's a trillion tons of excess carbon dioxide in the atmosphere, so even if we stopped every carbon dioxide emission tomorrow, the planet would still continue to warm for the next century.

My conclusion is that ultimately we need both, and that short term the energy spent on carbon removal solutions needs to be framed as an investment for it to make sense.

That goes a long way to explaining the pin count on those chips! The idea of that much current running through a bunch of angelhair thickness gold wire is horrifying.
Thank you. Sadly that's poorly phrased on my part. The bio says that I'm "into" that tech; i.e. it interests me. All I'm doing to capture CO2 at the moment is pay Climeworks monthly. I also took a sneak peek at their Orca plant in Iceland when I was there, but not much to see from the outside aside from a big 'keep out' sign.

I asked them if there would be any sort of tour available, given that the neighboring power plant has an exhibition (which is superb by the way! Easily worth the money, and I spent quite a bit of time geeking out there on.is/en/geothermal-exhibition/). Initially Climeworks responded, we exchanged a few emails, and one of their marketing guys wanted to give me a call, so I sent my number and... got ghosted. No replies to reminder/follow-up emails or anything. Bit bummed but oh well, didn't expect there would be anything available in the first place so I can't complain.

As for the other climate-related part of my bio, reducing emissions, there's a whole host of things but mostly things everyone already knows is an option: I chose to live in a place where I can commute by public transport, I buy and sell second hand instead of new when possible, reduce meat consumption (prioritized by a CO2/kg chart, which unfortunately includes cheese above chicken iirc) and buy veggie/vegan food to vote with my wallet, vote green in elections since imo basically everything else (short of war-like situations) can wait a few years, etc.
Yeps, that's a GCN, and probably the most popular GNN is indeed a RGCN :)

The transformer comment is interesting. They're very close, and in general, the tricks people use elsewhere are getting translated to GNNs: convolution, attention, ... . But scaling is still happening, so recent couple of years have gotten folks doing 1M-1B level, but not yet LLM scale yet. Critically, the scaling work is relatively recent -- good GPU impl, good samplers, etc -- and with a good trajectory.

We tracked GNNs for years but stayed away until heterogeneity + scaling started to get realistic for commercial workloads, and that's finally happening. Major credit to folks like deepmind, michael bronstein, early graphsage / jure, various individual researchers, and now aws+nvidia engineers for practical engineering evolutions here.

My life’s goals when I was a child were to get married, raise a kid, and to own the same Ferrari as Magnum PI. Done, done, and done (although the last one was mostly a bad idea). So I guess according to my standards I made it. The rest now is gravy.
Reducing emissions from the start, manufacturing, all sound like important parts of the solution! If you're looking for resources to get started, I linked Project Drawdown and others in another comment in this thread.
Ask HN: Why messenger search is wrong
Anytime I search for people in facebok's messenger app, ones that I just messaged five minutes ago, search results seem random.
I've never seen it give me a person I was looking for once at the top of results.

I wonder if it's just the app on android devices? What is the utility of such thing if it's designed that way?
It may be parochialism on my part, but as a Canadian, the first thing that comes to mind when hearing such a suggestion, is that it would likely result in us basically militarizing our border with the United States. It would impede trade and make it a hassle to visit and I'm not sure that would be in the interest of either country.
climate change regulation is the political equivalent of achieving fusion power, though. it's so hard. it's a planet-scale prisoner's dilemma.

every economic/political actor sees only long-term benefits from fixing the climate, and those benefits are the average of each actor's carbon contributions. everyone has an incentive to cut corners (spin up those coal plants to keep energy cheap) unless doing the right thing just so happens to be the easiest thing (solar costs less now.)

infinite economics and peace Nobels for whoever solves that. or physics Nobels for whoever makes fusion practical. it's basically the same thing, after all.
Trees can trap carbon, but only if you prevent them from burning or dying and decomposing.
Tax straddles—now illegal—is a new concept to me. A couple old articles about it from New York Times:

> An e-book is going to heavily (and negatively) impact the sales figures for the print book.

Well, if the price is the same, that hardly matters? Or are you implying unpaid/illicit downloads will be worse with a legal digital version as opposed to an illicitly scanned copy?

After buying an e-reader I can't defend buying print books from an environmental standpoint - it may be a sunk cost/resources fallacy - but with all the infrastructure for digital production, distribution and reading in place - print copies are a strict waste of resources.
I too had Dunninger's book when I was a kid. You may already know this but it was subsequently shown by magic historians that Dunninger actually never used some of the methods described in the book and never even performed some of the effects shown by any method. He just made some of the effects up along with their supposed methods to have more fodder to fill the book. It's a pretty fascinating story and perhaps his 'best' trick.
Executives typically do face consequences for making poor decisions. But the nature of their work means the outcome horizons are often way off in the future. C-suite leaders who perform poorly are eventually removed by the board and shareholders.

In some organisations there is so much fear of making poor decisions, that leading never really happens. And instead of thriving in a competitive environment, the company slowly dies.

A good middle manager is supposed to be able to mediate the strategic needs of the organisation as dictated by senior leadership, and the feelings of their team in a way that makes everybody happy. This is a very difficult skill.
Close, but without centralization, I can't imagine non-techies would use this.
It's a lot more than just shipping containers.

All the way down to the minerals being extracted from the earth. Nobody thinks about this... which is why we have all these smug EV drivers everywhere thinking they are net zero emissions.

Mining is dirty. Transporting raw material, smelting, transporting, forging, transporting, forming/shaping/fabricating/transporting again, etc... finally moving the finished products to the destination for final installation.

Nothing is "carbon neutral". It's a made up term to make people feel good about themselves.

I'd say it's a bit more nuanced than that - foreign countries are already quite active even when most don't realize it. Major political moves have been influenced by foreign country/ies, regardless of which side of the Atlantic you are - see both Brexit and the 2016 US elections.

Honestly, those numbers seem pretty good to me for a first generation product. As a baseline, at Ontario electricity prices that means I can get my carbon emissions to net zero ignoring any zero lifestyle changes for ~$5000/an. That’s high, but not ludicrous. I assume you could find further savings by further R&D on the process and by integrating electricity production. Now add in lifestyle and other technological changes (EVs, more efficient homes, more responsible purchases, more renewable electricity generation, etc) and we’re IMO into highly viable territory.
How do you expect that to work in the US?
If a nuclear device goes off in the Ukraine, it will be a false flag attack trying to incriminate Russia. With prevailing winds, any nuclear fallout from Ukraine will be spread right across Russia. Not the sort of thing any sane Russian would do.
We need CO2 capture because China and India will never go along with western efforts to tamp down on fossil fuel use before those countries fully industrialize. Beating that dead horse will only distract from efforts that could actually be useful.

Yes, the marginal income taxes were high but the capital gain taxes were low, so the rich didn't pay much. For example when the top income tax was 91% in the 1950s the capital gain tax was just 25%. See the historical top income and capital gain tax rates here https://ctj.org/pdf/regcg.pdf
I could be wrong, but I wouldn't think the autoscaling or load balancing would affect the websocket connection. There may be another aspect of the infrastructure that's preventing the connection though. Can you share more about the setup? Strange that the connection would succeed sometimes but not others.. This could be related to the configuration of some intermediate network layer. Eg. if Nginx is used, you may have to look into the settings that are needed to ensure websockets work well.

Yes, but it's often not nearly as newsworthy. A fossil being older is much more likely to change the timeframe for when something occurred. A younger fossil probably just means that same thing was still occurring
Nah, more like wrinkled gauze. In fact there is a photo of a beautifully low-tech model at the bottom: two styrofoam balls, one with a few loops of plastic thread stuck in it, one with a loop of a wrinkled, gauzy fabric. Both are casting a shadow on the wall; the gauzy fabric's shadow has a lot of subtleties of translucency that the thread doesn't, and does indeed look more like all the sun photos above it.
