Subject: Let's fix 'em before they break -- or are broken
An op-ed in *The New York Times* by Upmanu Lali and Paulina Concha Larrauri,
28 May 2020, is titled "Dam Failures Are a Warning". RISKS for years might
have more generally written "Damn Failures are a Warning."
After two recent dam failures, this article notes that "about 25,000 dams
are considered high or significant hazards if they failed." The final
paragraph is pithy, and very relevant here:
"We need a real plan and real money, and we need them soon. The
coronavirus pandemic, which we are spending billions to battle, should at
least remind us that a little bit of prevention can avert an enormous
amount of anguish."
This is pervisive advice, and should also apply to aging bridges, buildings,
roads, manufacturing plants, and even computer software and networks.

Subject: Concerns as rise of connected cars coincides with sharp increase in
cyber-attacks (Auto Express)
Cyber-attacks on connected cars rose by 700 per cent between 2010 and 2019,
according to new analysis, prompting experts to warn that drivers should
clear all personal data from their cars before selling them.
Some 67 per cent of new cars registered in the UK are `connected', meaning
they transmit data to their manufacturer via the Internet. By 2026, it's
thought that every single new car will be connected, according to research
by energy comparison site Uswitch.
The 700 per cent rise in cyber attacks on connected cars is shown by data
from security firm Upstream. In its most recent report on the subject, the
company analysed 367 global data-breach incidents between 2010 and 2019
involving cars, 155 of which took place in 2019 alone - a growth of 99 per
cent over the previous year.
One incident in October 2019 saw a mobile phone app Mercedes drivers could
use to locate and unlock their cars sometimes showed other people's
accounts and vehicle information. The previous month, thieves were caught
on camera stealing a Tesla in under 30 seconds using a keyless entry hack.
July 2019 saw an exposed database at Honda allowing anyone to see which of
its systems had security vulnerabilities, risking 134 million rows of
employee data.
Earlier in the year, Toyota suffered two separate cyber attacks in the
space of five weeks, with the offenders accessing servers that held sales
information related to 3.1 million customers. [...]

Subject: Riding the State Unemployment Fraud Wave (Krebs)
When a reliable method of scamming money out of people, companies or
governments becomes widely known, underground forums and chat networks tend
to light up with activity as more fraudsters pile on to claim their share.
And that's exactly what appears to be going on right now as multiple U.S.
states struggle to combat a tsunami of phony *Pandemic Unemployment
Assistance* (PUA) claims. Meanwhile, a number of U.S. states are possibly
making it easier for crooks by leaking their citizens' personal data from
the very websites the unemployment scammers are using to file bogus claims.
Last week, the U.S. Secret Service warned of *massive fraud* against state
unemployment insurance programs
<https://krebsonsecurity.com/2020/05/u-s-secret-service-massive-fraud-against-state-unemployment-insurance-programs/>,
noting that false filings from a well-organized Nigerian crime ring could
end up costing the states and federal government hundreds of millions of
dollars in losses.
Since then, various online crime forums and Telegram chat channels focused
on financial fraud have been littered with posts from people selling
tutorials on how to siphon unemployment insurance funds from different
states. [...]

Subject: Re: The Pandemic Is Exposing the Limits of Science (Bloomberg)
In recent decades people seem to have adopted a terribly simplified, rather
lazy, version of science. Consider the word's Latin roots, meaning just
"knowledge", not something miraculous. One good read is /Failure/, by Stuart
Forestein, subtitled "Why Science is so Successful".
The scientific method hopes to approach truth, but not usually in a
continuous way or by sudden understanding of everything that really matters.
As a discrete process, it can't quite be described as asymptotic. But
laymen (or women, we need a new word!) have come to expect that scientists
have perfect knowledge: The workers themselves generally see many things in
their results that need to be improved. Think of Newton's theory of
gravity, and his /Principia/, which were and still are marvelous
accomplishments: By the late 19th century it was widely recognized that his
version of gravity was not quite right, and Einstein in both special
relativity and then (another step forward) general relativity, took care of
much of what had been worried about. We certainly accept Newton as
accurately describing what happens if we drop a rock from our hands, but
NASA needs Einstein's improvements if calculating orbits, engine burn data,
etc. And nowadays there are discussions about how Einstein's world is still
not quite right.
In our current crisis we have tried to collapse the time scale to zero. The
amount of work and the knowledge gained have both been amazing. But it is
unreasonable to expect that complete and accurate results would be found by
now! The population at large has been led to believe that any technology
that requires you to think is thereby shown to be flawed. I would hope that
/Risks/ participants would understand how this works and how we need to
think and learn rather than to expect impossible payoffs! We can
pray/hope/wish/... for results quickly, but those don't come with
guarantees, and the answers probably won't be simple!
My own field is mathematics, where it might be easier to decide that a
result is really right than in some of the messier parts of our world that
have to deal with outside facts. But it is really sad to see people who
should know better seeming to misunderstand the whole way science works.

Subject: Risk of Polarisation (Re: Maziuk and Ladkin)
Regarding the contributions from Mssrs Maziuk and Ladkin; I do hope that the
polarisation and associated symptoms which we are seeing in U.S. and UK
politics will not infect RISKS!
I do not think Prof. Ferguson needs defending, but I was under the
impression that the "250'000 deaths" estimate, was based on the assumption
that NO lockdown measures were introduced.
"Coronavirus: UK changes course amid death toll fears"
https://www.bbc.com/news/health-51915302
If this forecast contributed to the decision to implement the lockdown it
certainly saved many lives.

I don't know why this ten week old piece was included in comp.risks: as if
it contained current and up-to-date information.
The *current* situation is that we *do* know which measures work to contain
the virus! Currently, 45 countries from around the world are winning: with
the number new cases per day dropping towards zero. 27 countries are
"nearly there", while 52 countries (including the UK and the USA) need to
take action.
The data is here:
https://www.endcoronavirus.org/countries
Back in November 2019 the USA and the UK were determined to be the two
countries best prepared for a pandemic.
https://www.weforum.org/agenda/2019/11/countries-preparedness-pandemics Both
countries knew that the pandemic was coming in mid February, both decided to
take little or no action. As as result, these two countries now have the
highest death tolls of all.
The USA and South Korea recorded their first cases on the same day:
South Korea immediately introduced a range of effective measures
including lockdown, extensive testing, contact tracing and isolation.
As a result the virus was contained with a total number of deaths,
as of today, of just 269.
By contrast, the USA has just passed over 100,000 deaths in the same time
period, and is planning to ease the lockdown while in 20 states the number
of new cases per day is still increasing.
It is estimated that over 30,000 deaths in the UK could have been avoided by
starting the lockdown a week earlier: such is the power of unconstrained
exponential growth.
https://www.telegraph.co.uk/global-health/science-and-disease/earlier-us-lockdown-could-have-saved-tens-thousands-lives/
(In searching for the above article I also discovered that more than 130,000
deaths in the UK since 2012 could have been prevented if improvements in
public health policy had not stalled as a direct result of austerity
cuts. Life is cheap in the UK:

Subject: Re: Misinformation (Ladkin, RISKS-31.84-89)
I think that most experts are all in violent agreement that these
epidemiological models are 'ill-conditioned', hence *any* noise in the input
can be dramatically *amplified* in such a way that it can often overwhelm
any 'answer'. Analogy: those screeching noises that are often heard from
audio public address systems that have positive feedback; the screeches
often overwhelm the person speaking.
Re: network-simulation Monte Carlo models, e.g., the Imperial model:
Monte Carlo models require enough iterations/runs in order to *average out*
the sampling noise (so that the 'result' is independent of the particular
random samples used), *which requires fully "exploring" the nether/tail
regions of the particular probability density function*.
The most trivial Monte Carlo model is that of estimating the *mean* of a
distribution by computing statistics from N samples. How many samples are
required in order to assure a reasonable estimate of the mean, where by
'reasonable' I mean an answer good to the first digit or so, *irrespective
of the random choices made* (one of the most substantial criticisms of the
Imperial model) ? Answer: N ~ O(distribution variance).
OK. Let's take an oversimplified 'superspreader' model for R0: 99% of the
time, R0=2, and 1% of the time, R0=98. The mathematical mean of this
bimodal distribution is 2.96, and the mathematical variance of this
distribution is ~91. But I just ran this Monte Carlo model and it takes at
least 15,000 random samples of this distribution just to get a reasonable
approximation to just one number -- its mean!
The reason why so many samples are required is that the relatively rare
event where R0=98 has to occur often enough to average out against the
vastly more probable R0=2 events.
But we're only getting started. R0 appears as the *base* of an exponential
in various epidemic models -- e.g., (R0)^(a*t), for some constant a.
But what if we have to sample, e.g., (R0)^10, i.e., a*t=10 -- to compute its
mean ? How many samples will we need to get a decent approximation ? (Note
that this is the 10-fold product of independently chosen R0's, so we can't
simply average numbers like sample^(1/10).)
So I ran another Monte Carlo experiment to compute the mean of the product
of 10 samples from our bimodal distribution from above. Even after sampling
1 billion such products, I still could not converge to even *one* decimal
digit of the mean, and the population variance was trending to O(10^15).
(Note that the worst case product has value 98^10 ~ 10^20, but also
probability (1/100)^10 = 10^(-20).)
How can we better to understand the probabilities of exponentials? Often
elementary statistics classes don't deal with *products* of random
variables, much less *exponentials* of random variables. One simple way to
understand such products and exponentials utilizes *lognormal*
distributions, which are not bimodal, and have heavy but not fat tails, and
are tractable. If X=L(m,v) is a lognormal distribution with parameters m,v,
then the distribution for the exponential X^n is L(n*m,n*v).
The mean of L(n*m,n*v) is exp(m+v/2)^n; the variance of L(n*m,n*v) is
exp(2*m+v)^n*(exp(v)^n-1). If we choose m,v to match the mean and variance
of our bimodal distribution above, then m~-0.1322 and v~2.4348, so the mean
of X^n is (2.96)^n and the variance of X^n is (2.96)^(2n)*(11.414^n-1) ~
100^n.
Since the variance of our lognormal (R0)^10 is ~100^10 = 10 *billion*, it
could take O(10 billion) random samples to get a reasonable approximation to
the mean of (R0)^10. I'd be willing to bet that the Imperial model was not
run 10 billion times, much less 10^15 times (for our bimodal distribution).
But this is merely one positive feedback loop in such a Monte Carlo network
simulation. What happens when there are multiple positive feedback loops ?
How many runs might then be required ?
The problem here is that our samples have to explore an incredibly wide and
incredibly shallow distribution, and then accumulate enough weight for each
sample to guarantee some reasonable accuracy for our result. But even if we
performed such a computation, what would it mean when the *variance* of the
distribution is so wide -- hence the weight of any particular value is so
tiny -- of what practical use is *any* particular value -- e.g., the "mean"?
This is the reason why "R0" models make no sense in the presence of
superspreaders -- there is no single 'R0' that captures any useful aspect of
the behavior of the epidemic.

Subject: Re: Vitamin C
The idea that megadoses of Vitamin C can prevent or cure disease is one of
those zombie ideas that just keeps popping up, in spite of being refuted
over and over. Maybe this is because it was originally pushed by Linus
Pauling, or maybe it's because Vitamin C generally doesn't do any harm.
Still, it's disappointing to see RISKS pushing this myth.
While there aren't many studies yet of Vitamin C and COVID-19, for obvious
reasons, there are lots testing its effect on the common cold. This is a
pretty representative one:
https://pubmed.ncbi.nlm.nih.gov/11700812/?dopt=Abstract No statistical
difference was found, with the placebo group actually showing slightly
better outcomes than the one that got the C megadoses.
The FDA has repeatedly warned companies against making outlandish claims
about Vitamin C's abilities to cure tuberculosis, cancer, Ebola, etc.:
https://quackwatch.org/cases/fdawarning/prod/fda-warning-letters-about-products-2017/fonorow/
Just because it's "natural" doesn't mean it's better.
[There's no point arguing with a total nonbeliever. However, since
you have goaded me, here are a few thoughts, that border on less relevance:
1. I have been told that Linus Pauling's notion of *large* doses of
Vitamin C was 1000 mg. It took 40 grams a day for Dr. Cathcart.
2. Many supplements are not providing what is on the label, and some
are laced with excipients that may be iatrogenic (such as
polyethelene glycol -- read the labels).
3. Who is claiming C is a CURE? Having a healthy immune system is
likely to be one of many *preventive* measures, and a good idea here
because of the next item.
4. The most serious cases of the novel corona virus seem to be targeting
people with already compromised immune systems.
5. Some in the medical communities are of course likely to be trashing
or ignoring many things that seem to have documented evidence of being
helpful, but are not high-priced pharmaceuticals. That is a long-time
battle. Not too long ago, there were many claims that there was no
connection between diet and health, no links between smoking and
health, and of course a former president who believed that ketchup was
a vegetable. Don't believe everything you hear.

Subject: Riding the State Unemployment Fraud Wave (Krebs)
When a reliable method of scamming money out of people, companies or
governments becomes widely known, underground forums and chat networks tend
to light up with activity as more fraudsters pile on to claim their share.
And that's exactly what appears to be going on right now as multiple U.S.
states struggle to combat a tsunami of phony *Pandemic Unemployment
Assistance* (PUA) claims. Meanwhile, a number of U.S. states are possibly
making it easier for crooks by leaking their citizens' personal data from
the very websites the unemployment scammers are using to file bogus claims.
Last week, the U.S. Secret Service warned of *massive fraud* against state
unemployment insurance programs
<https://krebsonsecurity.com/2020/05/u-s-secret-service-massive-fraud-against-state-unemployment-insurance-programs/>,
noting that false filings from a well-organized Nigerian crime ring could
end up costing the states and federal government hundreds of millions of
dollars in losses.
Since then, various online crime forums and Telegram chat channels focused
on financial fraud have been littered with posts from people selling
tutorials on how to siphon unemployment insurance funds from different
states. [...]

Subject: Re: The Pandemic Is Exposing the Limits of Science (Bloomberg)
In recent decades people seem to have adopted a terribly simplified, rather
lazy, version of science. Consider the word's Latin roots, meaning just
"knowledge", not something miraculous. One good read is /Failure/, by Stuart
Forestein, subtitled "Why Science is so Successful".
The scientific method hopes to approach truth, but not usually in a
continuous way or by sudden understanding of everything that really matters.
As a discrete process, it can't quite be described as asymptotic. But
laymen (or women, we need a new word!) have come to expect that scientists
have perfect knowledge: The workers themselves generally see many things in
their results that need to be improved. Think of Newton's theory of
gravity, and his /Principia/, which were and still are marvelous
accomplishments: By the late 19th century it was widely recognized that his
version of gravity was not quite right, and Einstein in both special
relativity and then (another step forward) general relativity, took care of
much of what had been worried about. We certainly accept Newton as
accurately describing what happens if we drop a rock from our hands, but
NASA needs Einstein's improvements if calculating orbits, engine burn data,
etc. And nowadays there are discussions about how Einstein's world is still
not quite right.
In our current crisis we have tried to collapse the time scale to zero. The
amount of work and the knowledge gained have both been amazing. But it is
unreasonable to expect that complete and accurate results would be found by
now! The population at large has been led to believe that any technology
that requires you to think is thereby shown to be flawed. I would hope that
/Risks/ participants would understand how this works and how we need to
think and learn rather than to expect impossible payoffs! We can
pray/hope/wish/... for results quickly, but those don't come with
guarantees, and the answers probably won't be simple!
My own field is mathematics, where it might be easier to decide that a
result is really right than in some of the messier parts of our world that
have to deal with outside facts. But it is really sad to see people who
should know better seeming to misunderstand the whole way science works.

I don't know why this ten week old piece was included in comp.risks: as if
it contained current and up-to-date information.
The *current* situation is that we *do* know which measures work to contain
the virus! Currently, 45 countries from around the world are winning: with
the number new cases per day dropping towards zero. 27 countries are
"nearly there", while 52 countries (including the UK and the USA) need to
take action.
The data is here:
https://www.endcoronavirus.org/countries
Back in November 2019 the USA and the UK were determined to be the two
countries best prepared for a pandemic.
https://www.weforum.org/agenda/2019/11/countries-preparedness-pandemics Both
countries knew that the pandemic was coming in mid February, both decided to
take little or no action. As as result, these two countries now have the
highest death tolls of all.
The USA and South Korea recorded their first cases on the same day:
South Korea immediately introduced a range of effective measures
including lockdown, extensive testing, contact tracing and isolation.
As a result the virus was contained with a total number of deaths,
as of today, of just 269.
By contrast, the USA has just passed over 100,000 deaths in the same time
period, and is planning to ease the lockdown while in 20 states the number
of new cases per day is still increasing.
It is estimated that over 30,000 deaths in the UK could have been avoided by
starting the lockdown a week earlier: such is the power of unconstrained
exponential growth.
https://www.telegraph.co.uk/global-health/science-and-disease/earlier-us-lockdown-could-have-saved-tens-thousands-lives/
(In searching for the above article I also discovered that more than 130,000
deaths in the UK since 2012 could have been prevented if improvements in
public health policy had not stalled as a direct result of austerity
cuts. Life is cheap in the UK:

Subject: Re: Misinformation (Ladkin, RISKS-31.84-89)
I think that most experts are all in violent agreement that these
epidemiological models are 'ill-conditioned', hence *any* noise in the input
can be dramatically *amplified* in such a way that it can often overwhelm
any 'answer'. Analogy: those screeching noises that are often heard from
audio public address systems that have positive feedback; the screeches
often overwhelm the person speaking.
Re: network-simulation Monte Carlo models, e.g., the Imperial model:
Monte Carlo models require enough iterations/runs in order to *average out*
the sampling noise (so that the 'result' is independent of the particular
random samples used), *which requires fully "exploring" the nether/tail
regions of the particular probability density function*.
The most trivial Monte Carlo model is that of estimating the *mean* of a
distribution by computing statistics from N samples. How many samples are
required in order to assure a reasonable estimate of the mean, where by
'reasonable' I mean an answer good to the first digit or so, *irrespective
of the random choices made* (one of the most substantial criticisms of the
Imperial model) ? Answer: N ~ O(distribution variance).
OK. Let's take an oversimplified 'superspreader' model for R0: 99% of the
time, R0=2, and 1% of the time, R0=98. The mathematical mean of this
bimodal distribution is 2.96, and the mathematical variance of this
distribution is ~91. But I just ran this Monte Carlo model and it takes at
least 15,000 random samples of this distribution just to get a reasonable
approximation to just one number -- its mean!
The reason why so many samples are required is that the relatively rare
event where R0=98 has to occur often enough to average out against the
vastly more probable R0=2 events.
But we're only getting started. R0 appears as the *base* of an exponential
in various epidemic models -- e.g., (R0)^(a*t), for some constant a.
But what if we have to sample, e.g., (R0)^10, i.e., a*t=10 -- to compute its
mean ? How many samples will we need to get a decent approximation ? (Note
that this is the 10-fold product of independently chosen R0's, so we can't
simply average numbers like sample^(1/10).)
So I ran another Monte Carlo experiment to compute the mean of the product
of 10 samples from our bimodal distribution from above. Even after sampling
1 billion such products, I still could not converge to even *one* decimal
digit of the mean, and the population variance was trending to O(10^15).
(Note that the worst case product has value 98^10 ~ 10^20, but also
probability (1/100)^10 = 10^(-20).)
How can we better to understand the probabilities of exponentials? Often
elementary statistics classes don't deal with *products* of random
variables, much less *exponentials* of random variables. One simple way to
understand such products and exponentials utilizes *lognormal*
distributions, which are not bimodal, and have heavy but not fat tails, and
are tractable. If X=L(m,v) is a lognormal distribution with parameters m,v,
then the distribution for the exponential X^n is L(n*m,n*v).
The mean of L(n*m,n*v) is exp(m+v/2)^n; the variance of L(n*m,n*v) is
exp(2*m+v)^n*(exp(v)^n-1). If we choose m,v to match the mean and variance
of our bimodal distribution above, then m~-0.1322 and v~2.4348, so the mean
of X^n is (2.96)^n and the variance of X^n is (2.96)^(2n)*(11.414^n-1) ~
100^n.
Since the variance of our lognormal (R0)^10 is ~100^10 = 10 *billion*, it
could take O(10 billion) random samples to get a reasonable approximation to
the mean of (R0)^10. I'd be willing to bet that the Imperial model was not
run 10 billion times, much less 10^15 times (for our bimodal distribution).
But this is merely one positive feedback loop in such a Monte Carlo network
simulation. What happens when there are multiple positive feedback loops ?
How many runs might then be required ?
The problem here is that our samples have to explore an incredibly wide and
incredibly shallow distribution, and then accumulate enough weight for each
sample to guarantee some reasonable accuracy for our result. But even if we
performed such a computation, what would it mean when the *variance* of the
distribution is so wide -- hence the weight of any particular value is so
tiny -- of what practical use is *any* particular value -- e.g., the "mean"?
This is the reason why "R0" models make no sense in the presence of
superspreaders -- there is no single 'R0' that captures any useful aspect of
the behavior of the epidemic.

Subject: Re: Vitamin C
The idea that megadoses of Vitamin C can prevent or cure disease is one of
those zombie ideas that just keeps popping up, in spite of being refuted
over and over. Maybe this is because it was originally pushed by Linus
Pauling, or maybe it's because Vitamin C generally doesn't do any harm.
Still, it's disappointing to see RISKS pushing this myth.
While there aren't many studies yet of Vitamin C and COVID-19, for obvious
reasons, there are lots testing its effect on the common cold. This is a
pretty representative one:
https://pubmed.ncbi.nlm.nih.gov/11700812/?dopt=Abstract No statistical
difference was found, with the placebo group actually showing slightly
better outcomes than the one that got the C megadoses.
The FDA has repeatedly warned companies against making outlandish claims
about Vitamin C's abilities to cure tuberculosis, cancer, Ebola, etc.:
https://quackwatch.org/cases/fdawarning/prod/fda-warning-letters-about-products-2017/fonorow/
Just because it's "natural" doesn't mean it's better.
[There's no point arguing with a total nonbeliever. However, since
you have goaded me, here are a few thoughts, that border on less relevance:
1. I have been told that Linus Pauling's notion of *large* doses of
Vitamin C was 1000 mg. It took 40 grams a day for Dr. Cathcart.
2. Many supplements are not providing what is on the label, and some
are laced with excipients that may be iatrogenic (such as
polyethelene glycol -- read the labels).
3. Who is claiming C is a CURE? Having a healthy immune system is
likely to be one of many *preventive* measures, and a good idea here
because of the next item.
4. The most serious cases of the novel corona virus seem to be targeting
people with already compromised immune systems.
5. Some in the medical communities are of course likely to be trashing
or ignoring many things that seem to have documented evidence of being
helpful, but are not high-priced pharmaceuticals. That is a long-time
battle. Not too long ago, there were many claims that there was no
connection between diet and health, no links between smoking and
health, and of course a former president who believed that ketchup was
a vegetable. Don't believe everything you hear.
