You don't need to transport hydrogen - you can generate it on-site from water at the fuel station. Although this will require upgrading the electrical grid.

Hydrogen is already in use in e.g. forklifts that need to operate 24/7 (because recharging is slow), so while the logistical problem could be solved, I don't think it's worth doing so in all cases. Hydrogen has it's niche.

(tl;dr below: there's stuff that hydrogen is bad at but batteries literally cannot do, so if we prioritize ditching oil then hydrogen wins by default in those specific niches.)

IMO hydrogen also makes sense for large vehicles that need a long range - planes flying the New York to London trip will need to either be synthfuel or hydrogen, and we haven't figured out how to make synthfuel at scale yet. So while synthfuel will eventually be better than hydrogen, it might not be available in time for our climate deadline.

Similarly, hydrogen might be a better option for multi-man trucks on a long haul (i.e. a truck with a bed in the back and a second (or even third) driver, so they can drive for two 10-hour shifts without stopping for a break) through low-infrastructure areas. Yes, that is a bit niche.

Also, cargo ships could use hydrogen right now with only a 1-5% loss in cargo capacity. Batteries wouldn't get 100KM let alone across the pacific and synthfuel doesn't exist.

In theory biofuels are also a drop-in solution, but modern farming is very heavily reliant on oil, so biofuels are mostly just fossil fuels with extra steps (and speaking of which: tractors need high uptime, you can't be constantly charging the tractor batteries on harvest day so once again, hydrogen tractors win by default). Also, unnecessarily straining our food supply is really dumb.
Also weird that they just repeated back exactly ChatGPT. How lazy can you be?

You're not really selling the job very well. I often hear about how people used to jump at job opportunities like this or working on pipelines or other infrastructure that required them to work remotely, and I wonder if there's some nostalgia colored glasses there, or if these jobs used to pay a lot better in inflation adjusted terms. Or if maybe there are just better employment options these days.
That's what I said. It's the cost of the powerplant that drives nuclear's cost. But you can reduce that dramatically via mass production of power plants. It will be a cheap source of electricity if done right. And we don't want just one energy source for everything anyways.
A good case that consistent brainwashing is likely laborious to do manually.

But why leave the job to humans?

I expect an effective approach is to have model A generate many possible ways of testing model B, regarding an altered fact. Then update B wherever it hasn't fully incorporated the new "fact".

My guess is that each time B was corrected, the incidence of future failures to product the new "fact" would drop precipitously.

Thank you for this point this is really interesting. I had a friend who is a recovering alcoholic living in TX. He would talk about going to get CBD gummies, and sometimes he'd say something about "wow, I took too many, I got messed up!". I was thinking "what a crackpot, you don't get high off CBD", I live in a legal state and I've taken CBD-only products. He came to live with me for a while and one day came home saying he'd bought some CBD. I asked him to show it to me, it was just regular 10mg THC gummies. Now this guy had a shaky relationship with the truth, but I thought THC was totally illegal in TX. This explains what was happening, I'm sure he actually was buying THC products.

Also, we smoked a joint together, and it was kind of scary. I've smoked my share of pot with lots of people, and I've never seen it affect someone like this. Not long after he moved away I read something else on here tying THC to schizophrenia. This guy was already bipolar but his affect under THC was different and really bothered me - I wouldn't smoke with him anymore after that one time. I'm no psychologist, but schizophrenic is how I'd describe his reaction to it.

I'll add that skepticism follows most addictions. I do have a problem with alcohol and this is part of the AA literature: only alcoholics understand an aloholic's relationship with alcohol. I've sat through enough meetings to know it. Lots of people in my life have asked "why can't you just stop at one or two?", the answer is that my brain handles it differently from theirs.

I think they're actually subtly different.

A bug is a computer program behaving unexpectedly. It can be caused by a defect. It can be caused by a bug crawling into the wiring and making the hardware malfunction. It can be caused by a cosmic ray flipping a bit.

A defect in a computer program is a place where the computer program that does not instruct the hardware to perform in a way so as to do what the program is intended to do.

Given the current (poor) state of our software, most bugs are defects, but not all. Sometimes it really is a bug shorting out a path on the motherboard causing the computer to not do what it was told to do.

Whether or not most defects are bugs is very case specific. Sometimes they're bugs. Sometimes they're just features that haven't been implemented yet, causing the computer program to not do what it is intended to do in an expected, rather than an unexpected, fashion.
I think that's just your own experience being extrapolated a bit too much. In my own industry I'm aware of a few dozen commercial products. Every single one has a first class Python API. Most only have the one Python API. All academic scientists and engineers in industry (in my field) use Python with a little Julia, Matlab, or C++. It's presence has grown a lot in the past decade. In IT, there's also Java, C#, and Go.

They mention the possibility of a mistake when measuring resistivity, which has already been discussed.

But yeah, the partial levitation is not a mistake. Their abstract suggests LK-99 is a "highly insulating diamagnet", but they are not even able to "detect any
reliable diamagnetic signal" with their instruments.

I'd rank the possibilities as: fraud, a different material, or some comical series of bizarre mistakes and contamination from the original team.

> Cigarettes are even worse they really have no benefit of any kind to anyone

No benefit of any kind to anyone?

Jesus, the arrogance of this guy. What makes you think you can make such blanket statements about everyone's experience like this?

Cigarettes are great for getting a boost of energy, or for having an excuse to talk to a stranger. And sure, both of those are things that we shouldn't need in a perfect society because we should all have enough time and calm to sleep and mental health care to get over our social anxieties. But that's not the society we live in--we live in a society where we can't be arsed to provide insulin for type 1 diabetics or school lunches for children. Giving nurses reasonable hours or high school students realistic dating advice aren't things in our society. So you'll have to excuse people for using the fucked up solutions that are available rather than the perfect solutions that aren't.

I'm not even a cigarette smoker, I just have a basic sense of empathy.
I was able to find a print ad for this thing[0], and it has 9.5 cubic feet of storage. Modern "full size" fridges have 2-3x as much storage (20-30 Cubic feet!), are going to be vastly cheaper to run/use, and have built in ice and water makers.

And you get can similar sized, simple fridges (that are still probably vastly cheaper) for like the same price as that one, but minimum wage is like 8x higher today.

Agreed. Quitting smoking (THC) and vaping have been the two healthiest decisions I’ve ever made. I was also having breathing issues, though thankfully never as acute an issue as you did.

This is missing the larger point, perhaps intentionally. Anthropomorphic descriptions color our descriptions of subjective experience, and carry a great deal of embedded meaning. Perhaps you mean it communicates the wrong idea to the layperson?

Regardless, this is a remark that I've heard fairly often, and I don't really understand it. Why does it matter if some people believe AI is really sentient? It just seems like a strange hill to die on when it seems - on the face of it - a largely inconsequential issue.
> According to domain name records, even if a site supports both IPv4 and IPv6 it defaults to IPv6. I would love to know why.

Newer is better? Good clients use the 'happy eyeballs' (rfc 8305) mechanism, which is roughly, open v6, wait a bit, open v4, use whichever connection comes back first. There's a bias towards v6 because often it's a more direct connection, and may work better, but it was also common to have non working AAAA records, so a delayed fallback is preferable to no fallback as used to be common.
What's the difference? I'm not sure how this renaming would change my behavior.
You'd be surprised. After all, if we were not lazy we'd be still digging the ground with our bare hands. "How do I get X while doing less work" is a kind of laze that defines human.

The storage level at Lake Mead has an annual spread of ~100ft; the dam is currently at historic low capacity and could hold about twice its current level: https://www.usbr.gov/lc/region/g4000/lakemead_line.pdf

Reservervoir dams certainly can store water and dispense it when appropriate.

Like I said, this is happening every day already, you can see it in the hourly data on wind/hydro generation share, and you can see it in the annual storage capacity data for Norwegian hydro.
FCC Slowly Updating Its Industry-Friendly Definition of 'Broadband'
And on the flip side, some energy markets like New England see a minimal variation in energy demand throughout the day, less than 10%.

Provision enough generation to satisfy peak demand and spend the excess power doing things like carbon dioxide sequestration or desalination in places with limited drinking water. Too much energy is a vastly easier problem to solve than too little. And the great thing about nuclear is that it's no more expensive to run at 100% capacity than 50%.

The material output of programmers is code. In that sense, programmer productivity is (|additions| + |deletions|) / time. Economically, it’s (|additions| + |deletions|) / wages paid.

This is how I would quantitatively measure the productivity of members on the teams I work with. If you look at this measure across your team, I think you’ll find it roughly matches your intuitive notion of who the most productive programmers are. I also think you’ll find story size positively correlated with the magnitude of code change or time.

The thing is, measuring how fast programmers output software isn’t all that useful.

Research out of Berkeley, 1 Aug 2023: theoretical analysis suggests high-Tc superconductors from apatite possible, points to synthesis challenges.

> Finally, the calculations presented here suggest that
Cu substitution on the appropriate (Pb(1)) site displays
many key characteristics for high-TC superconductivity,
namely a particularly flat isolated d-manifold, and the
potential presence of fluctuating magnetism, charge and
phonons. However, substitution on the other Pb(2) does
not appear to have such sought-after properties, despite
being the lower-energy substitution site. This result hints
to the synthesis challenge in obtaining Cu substituted on
the appropriate site for obtaining a bulk superconducting
sample.

Edit: Layperson summary from https://twitter.com/Andercot/status/1686215574177841152. It's crazy for the sim to not only be favorable towards SC, but also showing results that align with what the researchers proposed and what the replicators are experiencing (difficulty in synthesis).

> The simulations modeled what the original Korean authors proposed was happening to their material - where copper atoms were percolating into a crystal structure and replacing lead atoms, causing the crystal to strain slightly and contract by 0.5%. This unique structure was proposed to allow this amazing property.

> Lastly, these interesting conduction pathways only form when the copper atom percolates into the less likely location in the crystal lattice, or the 'higher energy' binding site. This means the material would be difficult to synthesize since only a small fraction of crystal gets its copper in just the right location.

Grey market isolated canabanoids are not at all the same. I would use caution with all of them, and particularly their sources, processing, and purity.
Yes. You just need to feed it bad data.
Seems the fastest way to clear this up would just be for the original team to send a sample to some other scientists for testing. That would solve any issues regarding other teams reproducing the material incorrectly, and at a first pass, what everyone cares about is whether its a superconductor at room temp, not how to make it.
If that’s what people where liquidating then it’s not problem, but 10,000 ETH and 2,000,000 ETH are just wildly different numbers here.
Solar thermal heating is not going to produce much energy in the winter when there's fewer hours of sunlight and more hours of cloud coverage - which just so happens to coincide with places that would need heating during the winter. Solar thermal performance is worse with diffuse light (read: overcast days) than PV solar, in fact that's a big part of why it was largely abandoned in the 2000s.

> China’s single party structure could liberalize capital controls faster than expected if incentives increased enough, which would enable faster internationalization of the Yuan.

The article kind of fell apart there. No, being authoritarian doesn’t mean it’s easy for the party to do whatever it wants. It doesn’t let them pull off magic tricks. In many ways it’s harder to do the right thing because they can’t kick the responsibility down to the next government.

China has known that they need to fix the housing market bubble for a decade now. Most likely the only way to fix it is to let it crash. But they can’t. Their legitimacy depends on GDP growth.

They’re barely keeping the economy together as it is, and they’re showing clear signs of being absolutely desperate to avoid a collapse. Liberalising capital controls at this point would almost certainly lead to enormous capital flight, which would be a self-sustaining downward economic spiral.
Thank you so much for answering. I was curious as hell but it felt rude to ask. It’s almost the most obvious answer, but I didn’t think of it once.

The DSM is just a compilation of named clusters of ambiguous and arbitrary symptoms that have been agreed upon by some arbitrary board of psychologist and psychiatrists.

It's not like the DSM is some infallible book of mental disorders backed by rigorous mathematical proofs. Rather, the DSM-V seems to be constantly criticized, lacking evidence, culturally biased, etc., and it mainly benefits health insurance companies more than patients and clinicians.

FWIW, the DSM, ICD-11, Neurology, etc. all have differing definitions of the word addiction.
Yeah, I’m convinced that the concentration of THC found in products these days is unhealthy. I’m a weed user myself, but since legalization I haven’t had a great experience due to the high THC contents.

"astroturfed"??? WTF?? All those players out there are real people.

This may be true, but if it's going to be used for housing foundations regardless (because there aren't competitive alternatives), then it's essentially a sunk cost.
