Cost is central to viability. Cheapest storage wins.

But there are a lot of different costs: capex and opex cost per kWh to store energy, capex and opex cost per kW to bank energy, capex and opex cost per kW to extract energy, cost for conversion losses, cost for banked energy losses, plus extra specific costs and sometimes specific benefits. Some of those costs will change radically with time as circumstances change; cost for conversion losses of all methods will fall as top line generation gets cheaper.

This is why synthetic fuels will be so important, despite low efficiency and high capital cost: the "specific benefits" exceed those.

Operating this thing via captured CO2, and feeding hydrocarbon synthesis and carbon sequestration, might improve its viability.
I assume “anybody” includes people with 0 hours of gun training, convicted felons, children, non-residents, non-citizens and those with serious mental illnesses?

Only slightly related, but a Japanese friend of mine has a story of interviewing a few engineering candidates for their remote crypto company. They all applied under Japanese names, claiming they were Japanese citizens in Japan. When the interview came around, they all spoke English with a Korean accent, and when asked if Japanese would be better they admitted they could not speak Japanese. When my friend asked around it sounded like many founders in the space have encountered this profile of applicant, and many suspect these are people working for the North Korean state.

If this is indeed North Koreans trying to get remote jobs, I've been wondering if their game is:
- Getting a job for themselves to bring income to their own household
- Getting a job for themselves to bring income to the North Korean state.
- Getting a job in a crypto company with plans of figuring out vulnerabilities and siphoning funds to themselves/the state.
- Getting a job for others, and selling the service of passing the interview.
I disagree with the idea that we shouldn't build capturing innovations on top of chimney CO2 emissions just because we need to eliminate those chimney emissions. Yes, we should reduce chimney emissions. But it appears that isn't going to be as easy as we'd like. It's why we're seeing various European countries turning on their coal plants again because Russia turned off the gas. We really need to have these capturing innovations that happen at the chimney too.

I wrote this other comment a couple of days ago: https://news.ycombinator.com/item?id=31850610

I don't see us succeeding in reducing our dependency on fossil fuels in the near future. We can achieve some reductions at national level. But these fossil fuels are simply going to find a customer somewhere else. It would be better if the West can provide cheap sustainable fuels or export/sponsor CO2 capturing solutions for foreign countries.
That's really interesting. What happened to 8pen, the domain is not used anymore. Are there still some implementations around?

What I'm pushing for is open formats + git for sync. That way, you can easily combine different tools. GitJournal is never going to do everything, the note taking app world is way too complex.

Instead, my plan was for GitJournal to be one other tool in your workflow.

Having more adventures. There's plenty good that can be done by trying out some routines and input chemicals, but at the end of the longest day, what memory is there in a forgettable life? A good adventure is sort of like a mnemonic, we encode stuff very well in stories. So in much of what we do, we ought to make an adventure of it.
It is a deterrence capability that can quickly reposition to protect other satellites in space. As to the actual payload of what it does in these situations, that is the closely guarded secret.

Other countries have deployed counter-satellite capabilities (the most interesting is the Chinese one that grabs and flings other objects out of orbit), so this is our counter-counter-satellite capability.
Eh, this was a pretty contrived read, and a bad way to think IMO. A healthy dose of pessimism makes sense but I've never believed in futility.
My takeaway from this passage is the simple reminder that we don't have to always assume the worst about people -- and if we consciously choose not to, then even mundane experiences can become generally more pleasant for yourself.

I've been looking for an app like this so I could mark quotes in a book I'm reading, save all the quotes under the book's url and then have these quotes highlighted when I open that url again. The second part needs an extension, but the first part can be done via the browser's "share" button in the context menu, but currently it forgets the url when creating the note.
Any life philosophy that helps one get through the day in a positive way is good. I do have a nit to pick with part of this one. It leans on the idea that "everyone is winging it all the time" and links to a Guardian opinion(?) piece where they pull quote from people who can't read a clock or tie their shoes. I think that's both not the right level of assumed incompetence that the author wanted to convey, but also reinforcement of a comforting excuse for failing to flourish. There is such a thing as expertise, and it (almost) always takes a lot of work to achieve it. So it both denigrates those who have worked hard to be competent in their field and gives aspirationals an out that potentially stunts their growth.

I agree that the mantra applies in some circumstances, like casual social interaction (although I'm sure there are subject matter experts in that realm too who could out-chat any of us), but applying it to your career and goals seems self-defeating to me.

But again, we are all different and different motivations work on each of us. Just my unsolicited opinion.
> neither of these are true because your mother's womb is all of environment, diet, not (your) genetics, and not controlled by a twin study.

> you're welcome to invent some kind of intervention study where you edit one twin's genes and not the other though.

And yet all of these criticisms are just saying we don't have a way to perfectly isolate the genetic effect. These studies still provide evidence for the impact of genes on whatever they are studying, even if the conditions in the mother's womb are also factor. The position that "everything but genes explains the observed differences" is the irrational one given the evidence.

> The other issue is that genetics don't typically make you better/worse in general, they make you more adapted to an environment.

I'm not sure why you are bringing this up? I didn't say anything about being better/worse in general (whatever that means)? I am talking about being able to run a 4 minute mile on Earth's surface (1 atm, 15-30 celsius, etc.)

> Though I remember hearing about this tribe of long-distance runners, who adapted to their lifestyle not through genetic traits but cultural ones

And yet, it's trivial to find papers mentioning how more genetic analysis is required, but there is evidence for genetic adaptation:

"The only genetic analysis carried out specifically in Tarahumara runners showed a striking enrichment in genes related to the production of the extracellular matrix of tendons and muscles in a gene ontology analysis (41). This genetic profile could provide the mechanical advantages for the foot strike that we mentioned above."

"Remarkably, it has been found that physical training in hypoxia can upregulate NKC activating molecules (52). And indeed, the activator gene, KIR2SD5, has a differential expression among the Tarahumara (19)."

> The best examples of genetic traits that do differ in humans are ones we got from elsewhere; humans really are extremely closely related for a species and haven't had much time to invent a lot of them.

You are talking about traits such as Tibetan adaptation to high elevation - something which requires genetic variability and selection pressure - whereas I am simply talking about the fact that there is genetic variability at the individual level that impacts performance.

Absence of a large number conserved genetic traits in specific populations, does not imply "human genetic differences are irrelevant at the individual level".

I am not claiming Norwegians as a whole have developed the "superhuman middle-distance running trait". There likely has been no (or little) selection pressure to do so, so the "trait" does not exist as something that is conserved in a specific population.

What exists is a lot of genetic variation that allows for some individuals (such as Jakob Ingebrigtsen) to be significant outliers when it comes to running a mile race. Because. of. his. genes.
Yes. It's also the fund where all the GPs are women.
To be honest I'd rather love to see "select folder for storage" become a standard app feature. Then I could just use whatever app I want to synchronize the files (in my case probably Syncthing). Integration of $APP_FEATURES and $SYNC_BACKENDS in apps is a major waste of developer resources and it also means that, as a user, I can never freely choose the app based upon its intrinsic features but also always have to keep synchronization in mind.
Maybe Millennials won’t, but Gen Z polls favor progressive politics by wider margin than ahead of Millennials.

Gen Zs political lean has not softened as they age into their late 20s, as it did with Millennials and older.

Minus their elders, Gen X is not a powerful enough political force in another decade to avoid capitulating on new new deal type government. Gen X is pre Information Age, no where near as savvy and aware of how technological society works, raised by a still very God-headed society (the US recently just crossed a threshold of <50% believing in higher powers; was >80% around 2000).

Urban growth has seen fewer teens get a license. Pee wee leagues participation was down before covid, as parents worried about future health, and cratered due to covid. Some unis have ended early education programs due to low enrollment. Essential workers are not staying in essential jobs as long, as they’ve seen they’re just a target for abuse by people who can’t feed themselves. 80% of nurses are considering leaving the field as they’ve just seen Americans rely on them like a mother rather than care for themselves.

There are a lot of trends that are really interesting to see, and the big gorilla is a bunch of senile leaders like Feinstein who apparently forgets peoples names minutes after introductions, and others who can’t understand ideas that aren’t presented in folksy slang. American agency is a lot like her memory; giving way to something else.
> in theory 3 space shuttles could deliver ~90 large warheads or up to 900 smaller warheads.

In practicality, all three shuttle launch facilities could not be used simultaneously. In fact, the two actually ever used could not have been used simultaneously. And space shuttles could not have been kept at standby, their launch sequence even in an emergency could never be reduced below 72 hours, and even that with tremendous difficulty.

And even if you could get three shuttles airborne at once, where would you land them? Also, I'm not sure if the Vandenburg launch could land after a single orbit, I think that the Florida launches would land a white sands.

> Space Shuttles would also have the ability to identify hard to find targets such as mobile ICBM launchers.

Space shuttles overflying the Soviet Union on a polar trajectory had no ability to maneuver, they had to fly a very specific trajectory to make the landing site. And no way an orbital vehicle could identify a target on the ground and alter its inclination to overfly it on that orbit. That would require both enormous Delta-V and high lateral G loads. Then they'd have to readjust the inclination to land.
Riding on the coat-tails of the noise problem is power. PAM-4 is an easy win because 2-level signalling is "over-margined" (which is why you don't need error correction with 2 levels, but you start to rely on it more and more as the # of levels goes up).

The "easiest" way to get around noise problems is to put more signal in, but power consumption increases with the square of voltage -- so it's extremely costly to overcome noise with more signal. However, noise is a fundamental limit; there's a set of tricks you can maybe do to improve it but for example, kT/q (thermal voltage of noise at roughly room temp) is about 25mV and that plays a role in a lot of device physics.

Thus most signals engineers would steer away from higher-order PAM and go to QAM, where they use phase to encode one dimension of data, and voltage to encode the other. This gets you out of a one-dimensional line of voltages and into a two-dimensional matrix of voltage vs. time to represent information.

This helps fight against that square-law term for power, but it comes at the expense of more precise timing sources. Time also has noise mechanisms, that are typically only overcome at the expense of -- you guessed it -- power.

At the end of the day, probably the most fundamental limit all computation will run into is power -- both how much you can afford to put in, and more importantly, the limit of what you can pull out reliably and efficiently. I'd be curious to see the plot of PCI-express energy-per-bit over its generations...I suspect it improves over time, but not improving as fast as bandwidth is going up, which means in net each link should run hotter.
I've been using Thunderbird since 2009 and while I really like it, I wouldn't call it lightweight and fast: it's pretty slow to start, takes quite a lot of memory and the search feature is really slow.

It's an excellent piece of software no matter what and I'm not sure you can do a much faster and lightweight email client anyway, because it basically needs to be a web browser to render HTML emails properly (but I'm pretty sure the search feature could be an order of magnitude faster)
AB 2847 is a clear attempt at a handgun ban (requiring California to ban 3 handguns for every new one- that's not a sustainable process). California also copied the Texas law about suing abortion providers, except for manufacturer's of gun parts (although that one hasn't gone into effect yet)

That is, the problem isn't just the ORM but the very different characteristics of the databases behind the ORM.

Any serious production app and I bet no one is touching that config. Especially, if it has been running for months with one db or the other.

And now, you're stuck with an extra database and a ORM.

I check mail on my phone with K9 (configured to leave messages on server,) possibly answer BCCing myself and eventually download mail forever on my laptop and remove from server.

My 35 years experience with email: I don't need to read old messages when I'm not at my computer. I never did before 2011 (first Android phone) and nothing changed after then. I can easily figure jobs that need constant access to the complete email archive. Not my one.

And I don't need mail on tablets and my old phone. I've got my main phone always with me, but the setup would be the same.

One reason it works for me could be that communication moved increasingly from email to messaging platforms and those are on my phone, except Slack which is confined to work boundaries. However I feel like I can lose all of WhatsApp and Telegram messages with no harm. I already lost a few years of WhatsApp and nothing happened. Who cares about conversations of 3 years or 3 days ago. It's mostly nearly unsearchable trash. And everybody else and I never had a verbatim trace of any IRL conversations for million of years, so they could be nice to have feature but not an important one.

But I'm doing my best not to lose mail. The long term important messages are in there.
You take the words out of my mouth. This is a strong and important realization, if you ask me.

Here's the Energiya launch site (a sequence of 360° photos, you can look around). What part of it could rotate, in your opinion? Keep in mind the tower is also missing the massive supports and the cosmonaut escape route, a humongous tube slide that couldn't move anywhere.

You might be thinking of the first R-7 launchpads that had to be rotated to a fixed angle before the launch because the control system from 1950's was unable to compute the roll maneuver in flight, aerodynamics being too complex for it.
> More to the point it shows the inherent weakness in open software - that is better open products have difficulty in competing against commercial ones because of stupid squabbles amongst the Open community - disagreements over minor technicalities and useability issues† means the greater objective has been lost.

What "greater objective" do you refer to? My objective is to have an OS that I have control over and can reasonably understand. For me that tends to be debian. So I guess for me the greater objective is satisfied.

> Turkey has also led a military campaign against Armenia together with their satellite just recently

That is not true, in 2020 Azerbaijan successfully liberated a region that was under Armenian occupation since 1994. I say liberated because that land was and is internationally recognized as part of Azerbaijan. Also, Azerbaijan suffered atrocities conducted by the Armenians, for example the Khojaly massacre[0]. Yes Turkey helped Azerbaijan, Russia helped Armenia. It was the first showcase of the Turkish drone technology in a war between regular armies but the Turkish help was not only in providing weapons, it was much deeper.

[0] https://en.wikipedia.org/wiki/Khojaly_massacre

When it comes to the Kurds, IMHO the Turks deserve most of the blame for the feud BUT what Turkey demands has nothing to do with Kurds but with internationally recognized terrorist organisations that operate in Turkey.

Think of it like this, if you are sympathetic of the people of Iraq for the horrible things that the USA did there would you also support ISIS? If your answer is NO then you don't have a case for supporting PKK against Turkey because PKK is a terrorist organisation that blows up public buses or kills teachers. If you are not familiar with their activities, there's ample amount of information online.
I joined my company last year when the stock was at an all time high and at the current price my total comp has dropped about 15%.

I asked whether they planned to make up for this, and the response from HR was essentially that it's tough luck.

I totally understand, that's how the stock market works, but it has definitely accelerated my plans to start looking around elsewhere (which would probably have happened anyway, it's not quite the right place for me). That said, I don't know what the actual refresher amount will be so it might be that it balances out somewhat.
Eh it should just die so it can be born again. I feel it's glacial in its updates and unfocused. People that like its current iteration are OK with it, people that want a more modern email client have to wait 5 more years, but then it'll be 5 years out of date.
In spite of the headline that might suggest otherwise, I don't think the author was suggesting inaction through futility and nihilism. Rather, as he mentions in the conclusion, it's about accepting that we don't have as much control over circumstances as we'd like, and to let go of external standards and situations:

...that's precisely when you can throw yourself at life's real hard challenges: the impressive accomplishments, bold life choices, and deeply fulfilling relationships. You get to live more intensely, because you're no longer making your full participation in life dependent on reaching some standard – of productivity, of certainty about the future, of competence, etcetera – that you were never going to reach in the first place.

That's on Walmart. Obviously we don't want to make things harder for already disadvantaged communities, but we simply can't let Walmart off the hook when they specifically tell their employees to complete transactions even when they suspect fraud.
