Huh? That's not a tuple at all! I don't understand why you say this so I'm not even sure if I should point out the obvious differences.

To wit, I've literally never used vector<any>, but tuple quite a lot(though often just because it's convenient for some metaprogramming hacks).
Doh! Thank you for the tip. I'll be honest, I was a little confused by the ~$1B market cap, but I did buy VGAC thinking I was getting a slice of 23andMe at a ~3.5B market cap, because that's how the press release made it sound.

In the future it would be nice if SPACs and the companies made that dead simple. I don't think this is something that needs to be regulated though. From the events this month I think we just need to allow the public to invest in whatever, abolish copyrights (which allow lies to flourish and buries the truth), and let the market figure it out.

Bayesian Analysis of Covid-19 Vaccine Efficacy
You mention economics.

Macro-economic theories are based on high-level relationships that economists have observed in reality, and that have some theoretical basis. For example, supply and demand can be represented as curves (aggregates of individual positions), and that in a perfect market the value of a good will converge at the intercept of supply and demand. There are a considerable number of assumptions required to make a statement like this, most of which are made to 'manage away' complexity.

Complexity theory helps us find ways to address and model complexity, such that we can reduce the number of assumptions required. For example, if we can build an agent-based simulation of supply and demand, and we model these agents as realistically as possible (few assumptions), we can then see if the same realisation of a good's value occurs.

The value in this is that we can then test the assumptions directly (what happens if 20% of people make irrational decisions?) and see how it affects the emergent behaviour.

Complexity theory can help in properly building these kinds of fine-grained simulations in a smart way, and can also help in understanding and debugging such simulations when the wrong behaviour emerges.

In my field (power systems) complexity theory can help us investigate and understand why large-scale blackouts have a fat tail distribution. That is, to understand why our macro-level statistical models aren't accurate in the edge cases. Primarily it is because these outliers occur 'emergently' due to the complexity of power systems, in ways that we overlook by applying old-school approaches to grid development and system operation.

In short: complexity theory helps us look beyond our 'mostly right' high-level statistical models and theories.
When we're talking about exchanging information between two parties, like on Sabine's hacker interception case, how is that quantum information exchanged? If it can be done through an electric cable, what forbids the hacker from just using a high impedance tap in the cable?

Interesting, and that's a cultural difference that I wasn't aware of. For context, I'm from the US, and very few people insist on titles of any kind. In grad school, most of the professors went by first names only. That said, some of the professors were German and had horror stories of their professors getting enraged at students having the wrong order of titles in "Herr Professor Doktor Doktor", or forgetting the appropriate number of "Doktor"s for each professor. How much of that is a location-based difference or a generational difference, I couldn't say.
It's a "hidden" (in that it's not documented very well or advertised much by AWS) feature of the AWS SDKs. I think it was likely added for debugging purposes originally, but security tools have started to hook into it as a more local and compete version of the kinds of logs you'd see in CloudTrail.

I've used it mostly for debugging and temporary monitoring of service calls.

“The” terminal degree is inaccurate. Ph.D.s in education are granted all the time to people who plan to become professors. The Ed.D. is also a terminal degree in education but the standards are much lower because it’s not for aspirant academics; it’s for aspirant principals and superintendents.

Equivocating is not the same thing as stating the equivalence of two things. Equivocation is "deliberate evasiveness in wording" and more particularly using one word but switching between two different meanings of that word in a tricky way.

If this article is equivocating (I haven't read it), then it isn't in the title. The title makes a clear claim that doesn't even equate disinformation and dissent. It rather makes the claim that the war is dishonest with its stated goal.

It just so happens that I think that's accurate.
Note the long disclaimer, though, clarifying among many other things:

"Possible Risks and Uncertain Benefits

- Immediate allergic or other serious reaction

- Unforeseen long-term effects

- Instillation/administration of the vaccine in an inappropriate way or in an infected area might increase the risk of infection by enhancing viral entry into the body

- Benefits are uncertain. There are extensive published histories of the materials and procedures described on this site, but every novel vaccine should be considered experimental, with the possibility there will be no benefit.

- Even if there are signs of immune response there is no guarantee this response is indicative of protection from SARS-CoV-2 infection, or if protection is achieved, how long it will last.

- Even if the vaccine confers protection from the virus, certain methods for assessing protection–such as measuring antibodies due to previous infection–might not capture vaccine-induced immunity. In such cases, infection, and thus a positive test result, are unlikely to occur. Immunity passports and other privileges given to convalescents might be difficult to obtain for those with vaccine-induced immunity.

- Use of this vaccine may change the efficacy of any future vaccines you may take or that are administered to you, in unknown ways."
If that's the case they wouldn't be able to collectively decide to keep expanding either, the decision would have to be made by the parts of the civilization that came in contact with the other civilization.

This implies a lot of things though - let us say we expand to Mars and manage to terraform it somehow - after a few hundred years though Mars has enough of a population that they end up needing new resources (obviously we need some story as to how they expand this quickly, I blame genetic engineering and Hoxar Matos the dictator-general of Mars who commands a billion test tube babies be born and raised by robots in the underground Martian nursery creches).

The model for grabby aliens is that Mars must find somewhere else to expand as they are part of the human civilization - but given human civilization it seems more like splitting the civilization and infighting to get more resources would be the most likely outcome.
Chances are your random sequences don’t match up with any protein sequences that are externally accessible for real viruses.

Worst case, your random sequences matches a surface protein of your heart or liver and you trigger the immune system to attack an organ you can’t live without

The most productive people in terms of output and success are the ones who do not talk about what tools they are using. But instead they almost solely talk about behaviors and ideas.

Once I realized that I quickly learned to ignore all of the productivity/self help space that plagues the internet today.
New responder. First off: I am NOT a free speech libertarian. I've reluctantly come to consider that lies that are believed by 40% of population are de facto facts. We can't so easily just take them off the menu because we "in our wisdom" recognize them for what they are. It will make them more sought after and forbidden. And because we can't ACTUALLY remove them like we used to be able to -- now that we've invented uncensorable internets -- we need new approaches.

I for one set my hopes on tools that augment empathy across wider digital chasms. After all, empathy is the biological "technology" that conscious networks already invented/evolved to stabilize the network. The pattern has been proven a success by virtue of the fact that... civilization worked up til now. We just need to bolt on some things that allow it to work just as well online as it does in meatspace

All imho, of course :) And very kindly stated, with willingness to be wrong
TS is taking on an impossible challenge in trying to add a robust type system on top of JS without harming compatibility. Its designers have chosen to favour compatibility where the two can’t be reconciled, and that is a reasonable, pragmatic choice. Better a new language that offers some improvements and lots of people actually use than a new language that offers somewhat more improvements that hardly anyone uses?

Unfortunately, this does mean TypeScript’s type system can’t be entirely sound. A classic situation that is also legal according to the rules of TS but “ought” to fail type checking is something like this:

let arr_num: Array<number> = [1, 2, 3]
let arr_opt: Array<number | null> = arr_num // Erm...
arr_opt[0] = null // ERM!!!

Now arr_num[0] is null, clearly violating the intended type constraint.

This problem could be fixed by making it an error to alias arr_opt to arr_num. However, that might also cause a lot of extra work for anyone trying to migrate an existing JS code base, particularly if the types involved are not of their choosing but instead determined by code written elsewhere.

For example, if you called a library function that returned an Array<number> and you passed that into another library function that required an Array<number | null> and wasn’t going to modify that array, enforcing the constraint could mean that working code was broken for no real benefit.

Then you get into deeper questions about enforcing immutability using the type system, and finding that again you’re building on sand because you still have JS underneath. IMHO, it’s hard to blame the TS designers for not wanting to go down these kinds of rabbit holes.
Magnetic Storytelling: Attract better clients (and create passive income)
There's a distinction to be made between chaotic and complex systems. You cannot model chaotic systems at their chaotic level of abstraction (higher levels may form more predictable behaviour, eg. The weather patterns). Complex systems cannot be predicted with certainty but you can interact with and model them. Consider the human body - it's impossible to know the total state of the body and predict exactly what will happen next, but we can model different states of the body and understand what interventions can counteract undesired states. Of course the specific fields for working with the body have made many discoveries long before systems science existed, but in the same way that the scientific method provides tools for understanding linear causalities across fields, systems science provides tools for understanding nonlinear causality across fields.

Masks yes. Or “travel bans don’t work.” The official response from the ministry of truth appears to depend on who it is that institutes them. If it’s a president that happens to increase WHO funding, as Biden has, there’s not much of any dissent at all.

This has been fixed. Appreciate the tip.
Had the university not been funded, the PhD student and the team who came up with the idea may not have attended said university and the discovery would not have been made yet.

In addition, universities often return back much more than they are given in funding, for example, universities in the ' League of European Research Universities' such as the University of Copenhagen return five fold the investment [1].

On a separate note, I don't understand why socially we've come to associate one type of doctorate (usually an M.D.?), for a physician, as the only type of "Doctor" when we're talking about a physician. I assume it's just a historical convention?

I have no skin in this game, but today it seems rather rude to not consider other doctors, "Doctors," but OK to consider just physicians, colloquially a "Doctor", a "Doctor."

If I had a Ph.D. you'd damn well be sure I wanted people to acknowledge my doctorate, even if it was in something else, such as mathematics, law, or education.
Do you need both, or is `display: none` enough?

> The short of it is that the title has arisen as a result of a form of professional jealousy, primarily with medical professionals. Everyone wants to stand out and mark their social class even in supposedly "classless" societies.

This is my understanding too. In my opinion, use of honorifics demonstrates a character flaw that should be corrected, not accommodated or encouraged.

My general M.O is to use the same level of formality with a person that they use with me. For example, if my physician uses my first name, I use hers.

This lets me match their desired level of familiarity, but disregards any pretense they might try to introduce.

Sometimes popular science is itself the misinformation. The authors stretch the findings to land in prestigious journals. The news stretches the findings further to sell clicks (c.f. Gell-Mann Amnesia effect). The people on the internet selectively quote articles and selectively ignore others. The algorithm tries to only show you content that you like.

The truth doesn't have a chance.
Here is an environmental impact study that Samsung had done a while back which shows the proposed expansion.

https://www.swf.usace.army.mil/Portals/47/docs/regulatory/pu...

Samsung's Texas fab produces ~100K wafers per month which puts it in the giga-fab category. if this expansion goes through that will easily double (or more) that production and make it THE largest non-memory fab in the world.

I've always found the Google C++ Style Guide useful, although it's about C++ in general and not specifically C++17 or C++20 (https://google.github.io/styleguide/cppguide.html). Sure it's specific to Google's need, but a lot combined experience went into it, and shouldn't be ignored.

There's also an interesting talk from CppCon 2014 where Titus Winter explains how they came up with it: https://www.youtube.com/watch?v=NOCElcMcFik

Here is something a bit similar from the Chromium team: https://chromium-cpp.appspot.com/

As for good projects written in C++, some of which is modern C++, I've always found LevelDB and Chromium to be good starting points. Here is a list of more projects which may help you: https://awesomeopensource.com/projects/modern-cpp

Finally, on your mention of "So I'm doubting if I should learn C++20 for now" => if you're in doubt, then 99% of the time the answer is no, don't spend time on it.

Learning has a diminishing return, especially once you reach the point of over-learning and spend time learning things you don't need or will never use. It's a lost opportunity as you could have spent that time learning something else that would actually be useful to you.

Wait until something either (1) become widely used and you can't ignore it, or (2) is required for you to get the job done -- because then you know it's actually useful for you to spend the time learning it.

I hope this helped, good luck with your learning!

Quantum information cannot be cloned. This forms the basis of quantum key exchange schemes that can say whether some communication (e.g. a keystream) was intercepted.
Universities started out as trade schools for the clergy, lawyers and doctors. The Ph.D. significantly postdates that. The title of doctor originally meant you were qualified to lecture. It was in use long before anyone was granted a Ph.D. as an honorific basically equivalent to calling someone learned.
So what he effectively did is create chitosan nanoparticles loaded with protein/carbon nanoparticles. This, I would imagine, is to allow the proteins to help bypass every protease, lysosome, and other defensive mechanisms that your body and cells have to protect against non-self proteins. These antigens, would then need to be presented by major histocompatability complexes to induce an immune response.
And with the property-based approach, test inputs can be generated that automatically increase coverage or that kill mutants.

The bane of mutation testing is equivalent mutants: mutations that aren't actually bugs, because they leave the program correct.
Yeah, it's a good point, and I'm indeed a bit guilty of hoarding data I can't immediately process.

However, the problem with the 'objective first' approach is that it's gonna require a lot of data to draw meaningful rigorous conclusions from small interventions, so I'm making sure to 'secure' the data first, and then gradually process it.

But also, it's a challenge in itself -- I'm automating a lot, sharing my system and trying to interoperate with existing tools, in the hope that my work can be useful to other people and make quantified self easier for them.

Complexity theory is interesting and useful.

However, because it's approximately descriptive, rather than accurately predictive, the field is haunted by quantum woo merchants, grand metaphysical unifiers, quasi-ecological musings and Buddha-lite pantheism. Which is neither interesting nor useful, except perhaps as a sociological phenomenon. Discuss.

Disagree because you’re looking at it as if my options are get Covid or take homemade vaccine.

I can pretty easily avoid Covid for the couple more months it’ll take before I get a real vaccine, so it’s low danger for me. I’m also younger and healthier so my risk if I get it is quite small. High enough that I’m modifying my life to avoid it, but still pretty small.

And since I think the homemade Covid vaccine is unlikely to work, it is unlikely to decrease the odds of any of the things you mentioned anyway.

However squirting strange chemicals up your nose adds risk. People die from Neti pots and that’s just water.

If I’m currently faced with the choices of taking a homemade vaccine or not taking a homemade vaccine, the latter is clearly the less dangerous course of action. I think that’s the spirit of the comment to which we were all replying, and it’s the actual choice being discussed.

Now if I were an 85 y/o diabetic in a nursing home and there weren’t a vetted vaccine available that might be different.
There _is_ disinformation by many actors and they have the aims as you explain them. But the issue is that Russia, China, _and_ the US are pushing agendas. We are not the shining knight of truth unfettered.

Likewise, there are quite a few who are _truly_ dissenting. Some may be mistaken on some points, but they are being quashed along with the malicious disinformation. It is not a good time for truth, since it is being lost in competing agendas, with very few major players being interested in the truth.

Our current climate doesn't encourage looking for truth. I think that is the major issue-- even if you don't believe dissent is needed, dissent is currently very unwelcome.

Even in business and tech, there is a lot of centralization and it is harder and harder to innovate as a little guy. That is a form of dissent, and it is becoming harder to do.
Do you really not understand the logic here, or are you making an ideological argument?

Try this analogous title, perhaps from an article arguing that exaggerated fear responses are all rooted in X or Y:

Surely, whether you agree or disagree with the article's thesis, you'd not argue that the article is implying that mice == spiders?
