I'm not sure it'd change the calculus for the UK or France because they are NATO members which effectively ensures their second strike capability. (It certainly might change the cost/benefit calculation on building submarines, though!) Israel probably doesn't even subscribe to a second strike doctrine given that the potential adversaries they're trying to deter don't even have nuclear weapons.

Scaling up could be limited by the availability of Boron:

> Boron is synthesized entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, so it is a low-abundance element in the Solar System and in the Earth's crust.[12] It constitutes about 0.001 percent by weight of Earth's crust.[13]

I just learned that the Budgie Desktop is written in Vala.

https://github.com/BuddiesOfBudgie/budgie-desktop

Also, on Arch I use Pamac as a GUI for package management and it is written in Vala as well.

I have used apps for quite a long time before realizing they were written in Vala. Not great for marketing but otherwise I would consider that one of its strengths.
The catch is that hydrogen storage is the smallest of the problems facing the nascent hydrogen economy. Energy losses in electrolysis and in the conversion from hydrogen to electricity are by far the biggest piece of the efficiency-loss pie.
> It is a well established practice in the US that billed prices have no bearing on reality and if you are insured, you have no liability to pay them

And if you're uninsured? Or your insurance refuses to cover it? Or it does, but with a high deductible?

My point is that the "well established practice" in question is useless at best and outright detrimental (to say the least) on society. Why even bother throwing out that number unless there's an expectation that someone would pay it?

>The protesting citizens do this as a plea for help from the national government. They know that the true believers in the national government need to be kowtowed to.

Could the plea for help from the national government be sincere? My understanding is that in early Soviet history, many people were sure that if Lenin/Stalin knew about the awful things local commissars were doing, the great leader would surely order such acts to stop.

Obviously by the Brezhnev/Andropov years very, very few people would be so gullible as to believe such, and I suppose that it's awfully late in the history of the PRC and CCP to expect otherwise of the Chinese, but the thought at least came to mind.

Another way to interpret this would be a (much, much more serious) counterpart, in the US and the West, during the past half decade of the de facto necessity in most parts of online discourse of prefixing anything that is not left of center-adherent with "I hate Trump, but".

I just clicked on an api.equifax.com link in a text message
I was filling out a rental application on on-site.com and a modal popped up telling me I had been texted a link and had 5 minutes to resend the link. I got a text from 32858 and it was of the form https://api.equifax.com/business/secure-mfa/v2/authentications/verification-tokens/<long hexstring>/verify. I clicked on it and it took me to a page that just had the text, "Authentication completed. Return to your application," or something like that. I don't remember what the domain was.

I couldn't find anything online about this, so I'm wondering, is this legit? Or is this somehow an elaborate ploy to steal my identity? What's also weird is that the website didn't change after I clicked on the link, but at some point I saw a back button on the page which closed the modal, and now I'm wondering if that button was there the whole time. Also, if I tap on the link again, I get redirected to secureauth.io/expired, but I can find no information about that domain online. My co-applicant never had the modal pop up and never got a text.

This number is nonsense. You can legitimately argue against the ethics of drone warfare (and likely win) without quoting completely false numbers.

Here's the wiki cohort estimate [1]. You can argue that it's off by multiples if you really want, but it's still not even in the same order of magnitude as your fake estimate:

> Taken together, independent estimates from the non-governmental organizations New America and the Bureau of Investigative Journalism suggest that civilians made up between 7.27% to 15.47% of deaths in U.S. drone strikes in Pakistan, Yemen, and Somalia from 2009–2016, with a broadly similar rate from 2017–2019.[6] Civilian casualties as a percentage of overall deaths were highest in Yemen and lowest in Somalia.[6]

My son and I got a lot out of a similar iPad app called Tynker, which we both ended up liking better than Scratch, which he used at school. Tynker has a physics engine, which opens up all sort of great game possibilities (we made a cheapo Angry Birds). Also as referenced above, Tynker has a slightly richer language that gets rid of the need for some bad practices (e.g., functions can return values, you can declare local vars vs all-globals-all-the-time, etc). Having the tool work well on a tablet also travels really well, and is a simpler container than a browser window for a really young kid.
In short, it is a writing tool. Are you a writer? Are you blogging? Are you working on developing a theory of something?

This is a very important sentence. Modern day knowledge workers are under constant cultural pressure that tells them everything they do is better if they shove it up its own ass. You don't have to create a document for every book you read, a record of every action you take. Without specific goals in mind obsessive self-documentation is just a massive level of busy-work that doesn't actually contribute to your skills or happiness.
Part of the problem is that even the state of stress at installation isn't known very precisely. I basically did some pre work on a similar idea.

I did all the computer related admin work at an ngo back in the day (and the transition from dos to windows was painful to say the least.

In our case Windows got itself thru the door only because we wanted to be able to use Aldus Pagemaker to do our DTP in-house.

The www was also a big windows ally. I remember having a perfect setup for uucp our mail, some gopher interfaces for the most savvy users, but once the web started to grow, it was all windows and trumpet winsock. Thank god for Peter Tattam!
This sounds like a line from Team America: World Police but unironically.
Yeah, dude, the number of 'normal people losing their homes' will create a revolution, and/or, consumer spending will crash, combined with the fact that a 'major component of GDP has crashed' (i.e. construction), that's 'extremely bad'.

The US was able to 'rebalance' by propping up some banks - but in reality they saved 'consumers' by taking toxic loan assets of banks balance sheet and absorbing it onto the fed balance sheet.

CCP can't really do that for houses that are not built.

The other issue is the size of that part of the economy in relative terms.

This is is not going to 'blow over' - everything, including Xi's totalitarian takeover, increased control and repression, issue of age, diminishing marginal returns to growth ...

... this adds up to a 'major shift' in what China is. We saw a different China in the 1990s (quietly building), 2000's (onto the world stage), 2010 trying to be a global superpower, threatening Taiwan, occupying S. China Sea etc, and now 2020's 'reckoning /rebalancing'.
I generally agree that tech monopolies are potentially bad for, not just national security, but general human wellbeing.

> The tech sector is out of alignment with law enforcement

In this particular case, I'd say that's a good thing. Law enforcement, and certain three letter agencies, have a terrible track record here. If big tech is making it a little harder for them to bypass basic privacy rights, I'm ok with that.
This blog post really captures the core of where null checking should go and how to capture that you've already vetted this field for correctness in the type system so that the rest of your code never has to worry about it -- and further, cannot because the types don't allow!: https://lexi-lambda.github.io/blog/2019/11/05/parse-don-t-va...

This is echoed in an amazing book called Domain Design Made Functional, which radically changed how I thought about what a type system is and what it can actually do for us if we lean on it correctly (even a relatively crummy one like Java's!).
The catch is that the parent article is extremely confusing.

The real research article

https://www.sciencedirect.com/science/article/abs/pii/S13697...

has nothing about the storage of pure hydrogen (a.k.a. dihydrogen), which would be very surprising if achieved, but about a better method for the separation and storage of certain unsaturated hydrocarbon gases, e.g. acetylene or ethylene (which can be absorbed by boron nitride powder and released later).
Is this supposed to be serious use of CSS or rather, as suggested by "Committing CSS Crimes", a critique of the absurdity of CSS?
Yes.

Of note:

> All up, the process consumes 76.8 KJ/s to store and separate 1000L of gases, which means it uses at least 90 per cent less than the current gas separation process commonly used in the petroluem industry.

> Even more significantly, once the gas is absorbed into the powder it gas can be transported safely and easily. When the gas is needed, the powder can be simply heated in a vacuum to release the gas unchanged.

Sadly, this doesn't put much of a dent in the larger issues around blue hydrogen.
And I know none. I don't recall ever actually meeting a Microsoft employee either, and I've been in tech a long time ( albeit in another country )

But picking Microsoft as an example or any of the faangs feels wrong, because they are the outliers. Millions of companies don't get that big and millions more fail.

The fact that a very small percentage of people do move between wealth classes and possibly social classes doesn't actually negate the original statement.
"vaccines"

real vaccines stop you from getting infected, spreading the disease or having symptoms, what's again efficacy of these vaccines at least against asymptomatic COVID? since we abandoned the idea that vaccines slow spread in any way...

Why would you get vaxxed if you are healthy person and your vaccination doesn't help anyone but you?

For the record in 11M Czechia 40K people died WITH COVID (that includes car accident victims, terminally ill patients it anyone enlisted in hospital who had to get tested) in more than 2 years, less than 1% of them were under 44. [1]

It could work if it gets to the point where 'only an idiot' wouldn't have broken the treaty, so you can just assume everyone has, because the idea is fairly obvious, the technology is easy, and there's not any other good options. Or if a rogue state does it or something like it, then you can assume the US and Russia have done it or will be doing it shortly.
Great lakes commercial fisherman and also crew on container ships have said for years that they see weird stuff dozens of miles offshore in the Great lakes.

Fish stories and all that. But there is precedent for submarines and even aircraft carriers in the Great lakes. Lake Michigan is filled with crashed trainer aircraft from WWII.
We saw the same thing happen in Korea and Japan after their post war construction, they moved up the ladder, worked hard, but then when they got a taste of real success there was a huge amount of speculation.

In the late 1980's Japanese real estate was the most valuable in the world, then it collapsed and they have not recovered.

This is a big secular shift for China. All of the previous projections were wrong, just like those indicating Japan would take over the world in the 1980's.

This is where China comes out of 'catch up' mode, and is now finding it's 'reality equilibrium' with the rest of the world.

Electrolysis is only one method to make hydrogen. Another one is using high-temperature reactors which have a much higher efficiency and don’t need as much energy.

It is quite the brain acrobatics to focus on it not being a test, duh, but a document. The point is what this document is supposed to document. And that is there being no indication, that you are infected with COVID.

The term is actually well defined, especially what is supposed to be documented by it. I am German and they borrowed it straight from the government regulation. The "Negativnachweis"

And you being vaccinated with a leaky vaccine doesnt mean there is no indication you are infected. Not in any way. This is misinformation that actually kills, because it allows COVID to spread. And its not information spread by some morons who drink bleach but by the government and quite literally taped to the doors of the figurative house of science. Because people lack the integrity to call out bullshit for what it is.
You made the same mistake as the higher comment. Yes, this is how it works legally in the US. But the concept of free speech is not tied to US law. It is a free speech issue and it’s perfectly conceivable that a countries laws would reflect these rights for social media protections.

The link is legitimate, but can't say the source from which it was generated. These kind of links can be generated by 3rd parties too.
These kind of systems are not always appropriate, but when they do, they work wonderfully.

Our use case was to build a service to manage the dynamic part of our infrastructure. These are infra pieces that are created/deleted/modified on the fly according to some policies, instead of defining them statically as code. The implementation is simply a lambda function that runs every minute, loads a policy, compares the current state of the system, and then creates/deletes/modify resources as needed.

I am currently in the process of writing a talk that I will deliver to the rest of my org. This will help me crystalize my thoughts, but here are some pointer on why I think it worked in this case:

* The service is stateless. On each run it just loads a policy, compares it to the current state of the system, and acts accordingly. This avoids handling complicated state or coordinating executions. In theory two policies could contradict each other, but in practice we partition our policies in such a way overlap is not possible.

* Operations are idempotent. This is one of the reasons the system converges to a desired state. This makes the service resilient to both failures and eventual consistency.

* Deviation from policies doesn't affect correctness. We are fortunate that our system is not directly customer facing. Deviation from policies affects only performance. The system can work several minutes (if not hours) outside policy band without consequences. This probably will be a critical blocker for most production systems.

Other than control theory and let it fail, I had the chance to play with other cool concepts while implementing this service. These are some of those:

* Parse, don't validate/anti-corruption layer: The service downloads and parses a policy at the beginning of each run. If parsing fails, it errors out. Otherwise, it passes the policy object to the rest of the execution. This makes the system easy to test, and avoids the anti-pattern of peppering your code with instructions reading input, just to find mid-execution that the policy was invalid.

* Pluggable policies: The main body of the service is a very simple sense/act loop. For the actors, we use a strategy pattern, where policies can choose what strategy to use. This approach has helped us to introduce new behavior with minimal code changes.

* Typescript as configuration language: This service replaces an older, less flexible one. A major pain of the old service is that policies where defined as Jinja templates over plain text files. This became unmaintainable as the number and complexity of policies grew. Our new service defines policies in Typescript. Policies are statically typed, and we use regular programming constructs (functions, loops, variables...) to build them at compile time. The output is still a plain JSON file.

Hope that helps.
They do need to do a bit of heating to extract the hydrogen, but probably not a huge deal as compressed H2 gas when expanded out and burned would pull energy from the environment — so there is energy being used there as well.

This is not what happened. (The Fed never bought the toxic assets. It bought Treasuries and super-safe nontraditional assets off owners of toxic assets so they had the liquidity to resolve themselves. But the toxic stuff ended up in other places.)

This doesn't answer the question. China also sells mortgage backed securities and has parts of its financial sector operating with little regulation. Something like 40% of outstanding Chinese loans are tied up in shadow banking activities. It's entirely possible that a failure to pay mortgages leads to contagion, especially because the mortgages aren't even backed by anything in many cases. In some ways, we're already seeing contagion. A lot of these developers are folding due to new regulations on how much debt developers can take on.
This article is complete BS. The abstract of the publication does not mention hydrogen at all, and in fact concerns storage and separation of acetylene and ethylene gas, which are hydrocarbons, not hydrogen.

In which volume? The public abstract of the paper at https://www.sciencedirect.com/science/article/abs/pii/S13697... states

> The mechanochemical process produces extremely high uptake capacities of alkyne and olefin gases in the BN (708 cm3/g for acetylene (C2H2) and 1048 cm3/g for ethylene (C2H4)) respectively.

I assume that is the volume of gas per cm3 of Boron Nitrate.

As I said, I will believe it when I see it. Heard the same doomsday stories over and over at this point.

The most likely way this plays out is CCP slowly nationalizes Evergrande and other embattled developers (bond holders and equity investors 100% screwed), sell the unfinished projects to developers that didn't run themselves into the ground for them to be completed. This is already happening.

As much as people want to believe there will be collapse I just see it as incredibly unlikely given both track record and the iron grip that CCP has over the Chinese state banks. Without a failure in the banking sector I just don't see significant enough contagion to cause long-term damage.
Having lived in a mobile home for a couple years, I can say that a large part of my hatred for OSB/particle board comes from that house. It seems pretty much every mobile home i've ever been in suffers from sponge floor, which is the OSB degrading to the point that the carpet is providing more structural support. Eventually the flooring gives way, and its becomes possible to stick ones floot through the floor.

When I was living in that home (as a Highschool student) one of the things I spend many hours doing is ripping up the floors and replacing them with actual plywood, which seems to be significantly more robust when used as a flooring material.
