I am glad you brought up bra-ket notation. I have wasted a lot of time trying to understand how to formalize bra-ket notation. I kept seeing the words "C* algebra" and "rigged hilbert space" being thrown around. I recently learnt the full story:

- Von Neumann's paper "mathematical foundations of quantum mechanics"[http://alpha.math.uga.edu/~davide/The_Mathematical_Foundatio...] builds up hilbert space theory and solves problems without ever using dirac deltas. So if one wants to use bra-ket without dirac deltas, this is the formalism.

- To make dirac deltas themselves precise, forgetting the bra-ket context, one uses the language of distributions. So we view the dirac delta distribution as a linear functional which takes a function `f` and spits out the value `f(0)`, and all that jazz.

- To join distribution theory with Hilbert space theory, we construct rigged Hilbert spaces. This is the theory that carefully delineates from which subset of Hilbert space we can pick kets, and from which larger space of distribution we can pick bras, to allow the bra-ket formalism to continue to work.

I found the reference "The role of rigged Hilbert spaces in QM"[https://arxiv.org/pdf/quant-ph/0502053.pdf] incredibly valuable.

This is the sort of thing that drives me nuts. I bought and tried to read Shankar, because I was told it is "rigorous". It's not. It casually uses dirac deltas and all sorts of "punning" with bra-kets with zero formalism.

Do you have a good recommendation for learning this heat and work perspective? I always found this confusing [eg. "adiabatic work", "infinitely slowly" and all that]. FWIW, I wanted to learn stat-mech for a closer look at entropy and information, which I felt I got with some LL.
The problem is you've now screwed all of the people who own the stock. So you diversify the ownership of this particular company, but all of the mutual funds, and other people who own the stock just get to suffer a huge loss?

And what prevents another entity from buying up a huge portion of the stock using a different company? This new entity could be controlled by some other billionaire or group and you gained no diversity at all.
The conclusions are painted with too broad a brush in my view. People don’t split binary into thrill-seekers and conflict-avoiders, it’s more of a spectrum, and people can exhibit both qualities in different circumstances.

In my opinion the real difference in leadership style derives from theory x (top-down) vs theory y (bottom-up). If you haven’t read up on that you definitely should. I’ve noticed I can work with managers regardless of their risk profile, but I do not thrive under theory x leadership because it is too stifling.
all of them know. some of them invent and believe intricate fantasies in which everybody is faking it, nobody is comptent, and is actually secretly behaving like them.. to justify their behavior.
None of those things was solved in the last 3-4 years though.

Some might now be done via AI, but is it done any noteceably better than 3-4 years ago? I certainly don't trust my camera to adjust itself, or the sleep analysis to be any good, or the article recommendation to not recommend based on outrage, or the spam filter to work at all.
The traditional way to make this project feasible is to give the billionaires (and maybe even a few aspiring multimillionaires; one mustn't be too picky in fundraising) a piece of coloured ribbon in exchange for their donations to their fellow citizens, as well as inviting them and their families (especially marriageable children) to an annual cell-phones-in-the-fishtank no-non-donators-allowed party celebrating their commitment to their nation.

(TIL "Eat the rich" is attributed to Rousseau, not to Wells' Eloi/Morlock dynamic. I am disappoint. "Tax the rich" is apparently a 3rd rail in US politics. "Feast the rich", on the other hand, would use the carrot of exclusive membership — what Capitalist could resist such an incentive?)

Compare with ruby: `gem install the-gem`. Done. No "virtual envs", no plethora of similar but different tools to do slightly the same thing / whatever, no preconditions, no step by step procedures. Simplicity is important!
Buybacks were never the problem.

Buybacks as part of acquisitions, using the acquired companies resources to take complete control for less than its market value, are a ridiculous accounting trick which should never have been permitted.

Buybacks combined with tiered stock are also pretty fraught.

Buybacks by existing leadership in pure-common-stock orgs are fine.

That's the whole point. If you are still using classical solutions for these things that are years old, you are far behind best experience and the competition. As an example, noise removal in low light images has advanced tremendously each year with stunning gains. Same goes for grammar correction and auto-correct. You can see the difference in Siri and Google Assistant that is literally an order of magnitude. Siri even has trouble doing proper voice recognition and as Apple does not even know how to do search, its question answering skills shines only for highly curated tasks. First thing I've always done on my iPhones is to turn it off. However, Google had been amazingly improving these stuff every year. The end result is that while I do use iPhone, I tend to use mostly Google services and when something is only available on Android I get a tremendous itch to switch.
Then your pay will be cut too. Lots of people think that is unfair because you are doing the same work, but those people just don't understand that salaries are market based.

Also you might think "my company doesn't cut salaries", or "I just won't say I've moved". That might work if you stay at the same company for the rest of your life, but if you move jobs there's no way you'd get the same deal.
IRL, cops behave far more threateningly than calling someone a “bitch” on Twitter, and yet they don’t get charged.
> In addition, lisp programs (at least in these environments) don’t have “main”.

But they have similar mechanisms.

In Symbolics Genera 'programs' are called 'activities'. They can be started by keyboard shortcut, command, an application menu or by a general function, where the activity is an argument. Usually each 'activity' runs a command loop.

Additionally images have named lists containing functions, which are executed on certain event. For example if an image starts, a 'cold boot' list will be executed. If one has registered starting application programs (activity) - remember activities have names like editor, listener, mail client - they will be started by the operating system after a boot.

If a user logins on a Lisp Machine an init file gets executed. That init file can also contain general forms which start activities.
Virtual envs never made sense to me. I never understood what made Python so special that it needed these.

I never got where the virtual env is, what it does and why I need it.

Why can't I just `pip3 install xxx` and be done with it?

Python dependency management is a nightmare, and it seems like it always will be due to the insane number of so called "easy" solutions.

Roughly 60% population have HSV-1 (and 10% HSV-2). I don't think that the percentage of people getting daily antivirals is the same.
While the various xep might be a confounding factor - the biggest issue I see today with xmmp is that end to end encryption and perfect forward secrecy is optional and bolted on.

I think Facebook and Google's embrace-extend-extinguish (both fb messenger/chat and gtalk used xmpp - neither allowed federation - and created artificial silos) was probably the worst thing for open standard chat.

Gmail isn't quite big enough to have been able to fracture email yet - but not for lack of trying (years of poor imap support, strange handling of threads/top-posting etc).

It doesn't matter. You can argue that "people shouldn't fall prey to groupthink" and I'd agree with you. But they do. We're talking about a group of 2.6 billion people, not an individual. On average, people are a product of their environment. And the environment, in this case, is a bad one. It promotes all the wrong things and the incentives are in all the wrong places.

The question is, have you? Because inflation is precisely the biggest problem when it's applied. It works on certain scenarios but it's not a long term solution.
Look at the root causes of increasing wealth inequality. Today’s global, connected world has allowed the winning of much larger markets than before. It is very similar to how industrialization allowed the accumulation of huge amounts of wealth. This global, connected world has also devalued low skilled work. Increasing amounts of work will be devalued.

Any solution should be addressing these root causes while trying to not lose many of the great benefits.

One aspect should be creating a basic living standard.

Another aspect should be maximizing human potential. This isn’t just education but also opportunity. This isn’t just STEM but other human potential: music, art, etc...

The last issue is how to pay for it. Progressive taxation makes sense as does a luxury tax. An inheritance tax makes sense because it still motivates individuals to produce.

That doesn't make any sense. The key part of Bergstrom's logic is here:

"But ex post, holding the epidemic trajectory constant, it means that the disease is more transmissible per contact event than you expected."

...but that's wrong. The epidemic trajectory isn't constant (R0 is not an innate property of a virus; it changes with context), and it's pretty likely that we've completely mis-measured it by sampling from the wrong population. Our estimates for R0 are mostly model extrapolations from PCR testing data, which are not uniformly sampled from the population. If anything, in fact, they're heavily biased toward the susceptible population.

In other words, because we're sampling disproportionately from the most susceptible population, our estimates of R0 already seem high. If you sampled randomly from the population of less-susceptible people, you would see that the R0 is much lower than you originally predicted.

On top of that, there's absolutely no reason to believe that cellular immunity would make it seem like R0 is lower in any particular population: T-cell-mediated immunity is a late response. It can reduce the severity of an infection, but it's still highly likely you'd show up as a positive PCR test, and count toward an R0 estimate.

So you have a measurement based on a test that isn't strongly affected by cellular immunity, derived from a population biased toward the most susceptible individuals. If you have to doubt something here, you doubt the estimate of R0 (i.e. the model), not the observations of reality.

This is a strange and IMO unsatisfying book review, as it's largely a summary without much in the way of analysis or evaluation (except for the explanation of which real-world critics Kaufman is targeting). But perhaps this is an attempt at a demonstration, by its absence, of the value of criticism - which would be an appropriately meta way of responding to Kaufman.

The lead hypothesis offers no explanation for the huge surge in crime in the late 60s and 70s. However the fact is that criminal justice system was handicap during that time. Crime just wasn’t prosecuted or punished in that period.

I would also say that they are far more likely. correlation is not causation. Lead exposure and crime are very widely separated variables.

I do agree but perhaps Facebook hastens a journey that some users were already on, towards more socially destructive behaviour. Perhaps the social proof of seeing those users encourages others to join on that path?

Ultimately though i agree with your point which means even if i am right in thinking Facebook accelerates and encourages bad practices - it doesn’t matter because responsibility lives with each user, each individual.

I reckon all the laptops I was exposed to in the early-mid 90s through school and my father’s work were Toshibas, to the point where I may even have thought Toshiba was the only company that made laptops.

Climate change isn't a partisan issue. Policy will be, but the "narrative," as you call it is established science.

> Now imagine a conservative media making such quick connections between, say, a bump in immigration rates and a crime. Or even saying: "that crime spree? Immigration is to blame". That's obvious fake news, right?

Both illegal and legal immigrant groups have lower incarceration rates than native born Americans. So, whenever a right-wing pundit says that immigration is to blame for crime rising, there likely is statistical fuckery or outright lies.

However, it is hilarious how, even while being treated with kid gloves, you are still whinging about there being a bias against the right wing.
That's such a little neat trick, it's great. Sometimes I think that some civilizations back then had figured out more about how to be a society at least in some respects, than we have today.

I like this article. Please check
https://stevenpinker.com/files/pinker/files/pinker_comments_... Steven pinker makes some good points in this short essay why there should be more skepticism towards this hypothesis:
“ Also, the parallelism in curves for lead and time-shifted crime seem too good to be true, since the lead hypothesis assumes that the effects of lead exposure are greatest in childhood. But 23 years after the first lower-lead cohort, only a small fraction of the crime-prone cohort should be lead-free; there are still all those lead-laden young adults who have many years of crime ahead of them. Only gradually should the crime-prone demographic sector be increasingly populated by lead-free kids. The time-shifted curve for crime should be an attenuated, smeared version of the curve for lead, not a perfect copy of it. Also, the effects of age on crime are not sharply peaked, with a spike around the 23rd birthday, and a sharp falloff—it’s a very gentle bulge spread out over the 15-30 age range. So you would not expect such a perfect time-shifted overlap as you might, for example, for first-grade reading performance, where the measurement is so restricted in time.”

I’m also not convinced on your point about crime in California. The police have essentially ceased prosecuting many of those petty crimes. It makes sense that they would go up with no deterrence.

Exactly, and I'm also scared at how open the current administration is about trying to break the postal service right before a record mail-in election. Call it absentee voting fraud, then appoint a partisan postmaster to mix up the organization as much as possible and make changes intended to cause mail delays. Plus the comments about delaying the election.

OP was taking the NYT method such as in this article about a possible vaccine:

>The goal is to prevent haphazard or inequitable distribution of a treatment or vaccine when there isn’t enough to go around. Such a system has already been used in allocations of remdesivir, the first drug shown to be effective against the coronavirus.

>“This is all very new,” said Dr. Douglas White, an ethicist and vice chairman of the department of critical medicine at the University of Pittsburgh, which began using a weighted lottery last month to distribute remdesivir.

It's quite easy to see how the jump to vaccine can be made when they really meant treatment.
