    Best to read up on the device your surgeon advocates BEFORE undergoing

    monetary incentive they receive for promoting the recommended device,
    etc. Any evidence of historical device efficacy and patient outcome NOT prepared or sponsored by the manufacturer?

    Wade Rousch, Scientific American, May 2020, p.26

    "In the speech-recognition business, 95 percent accuracy might as well be zero." That's 1 of every 20 words erroneously transcribed automatically.

    'ASR systems may never reach 100 percent accuracy. After all, humans do not always speak fluently, even in their native languages. And speech is so full
    of homophones that comprehension always depends on context. (I have seen transcription services render `iOS' as `ayahuasca' -- and `your podcast' as `your punk ass'.

    A misplaced comma in a business document can dramatically affect legal judgment. Proofreading remains an important editorial function. (see https://www.bbc.com/worklife/article/20180723-the-commas-that-cost-companies-millions .)

    Risk: Over-reliance on ASRaaSWP -- automated speech recognition as a service without proofreading.

    In contrast to ASR, https://www.nytimes.com/2020/04/08/technology/ai-transcription-human-services.html
    testifies to the effectiveness of human-driven transcription. Subject matter comprehension, contextual awareness, and conversational immersion elevate transcription quality. These factors are substantially out-of-reach for ASR.

    The technological race to improve ASR, and retire human transcription,
    reminds me of "John Henry" per https://en.wikipedia.org/wiki/John_Henry_(folklore). Perhaps an undiscovered Agatha Christie story entitled "Death by Transcription" offers a
    post-mortem?

    Grail' Targets Since 2012 (Davey Winde)

    Davey Winde, Forbes 7 Apr 2020 via ACM TechNews, 13 Apr 2020

    A BlackBerry research and intelligence team said five Chinese advanced persistent threat groups have long been attacking Linux servers that
    "comprise the backbone of the majority of large data centers responsible for the some of the most sensitive enterprise network operations." Particularly worrying is evidence of the attackers using a previously undocumented Linux malware toolkit including at least two kernel-level rootkits and three backdoors, actively deployed since March 13, 2012. Analysis associated this toolkit with one of the largest Linux botnets ever found, with a significant number of organizations likely infected. Targets include Red Hat Enterprise, CentOS, and Ubuntu Linux environments for purposes of cyber-espionage and intellectual property theft, with researchers describing Linux defensive capabilities as immature at best. Former U.K. Military Intelligence Colonel Philip Ingram said mitigating such exploits entails "treating [the threats]
    as if they are ... as much a threat as any other operating system." https://orange.hosting.lsoft.com/trk/click?ref=3Dznwrbbrs9_6-24b68x22187fx068278&

    As Washington tries to take China, Russia, and India to task, these nations
    are mounting defenses in the name of `cybersovereignty'.

    The US and other democratic states don't engage in many of the Chinese or Russian activities that so worry policymakers in Washington, like
    intellectual property theft. Clearly, these behaviors directly contradict
    what many countries deem to be fair trade practices. But some issues, like
    data localization mandates and data security regulations, are bound to
    receive more domestic focus from the US and its democratic allies and
    partners. How American policymakers reconcile these facts when addressing perceived digital trade barriers elsewhere -- all the while combatting [*] false equivalencies is crucial for digital diplomacy and trade going
    forward.

    via ACM TechNews, 13 Apr 2020

    California's Department of Motor Vehicles has authorized an autonomous technology startup to test two driverless delivery vehicles in nine
    cities. Startup Nuro will use its driverless low-speed R2 vehicle to begin conducting deliveries with local retail partners. The startup has been
    testing autonomous vehicles with safety drivers on the state's roads since 2017. Said Nuro's David Estrada, "Our R2 fleet is custom-designed to change
    the very nature of driving, and the movement of goods, by allowing people to remain safely at home while their groceries, medicines, and packages, are brought to them." In February, Nuro was granted permission by the National Highway Traffic Safety Administration to deploy up to 5,000 low-speed
    electric delivery vehicles without any human controls in Houston. https://orange.hosting.lsoft.com/trk/click?ref=3Dznwrbbrs9_6-24b68x221883x068278&

    Subject: Legit email/websites considered harmful, or RISKs in the time of
    COVID-19

    Earlier this month I received an email purporting to be an offer from UCSF
    (a premier medical school/hospital in on the US West Coast) to access information about COVID-19 through a third party (Emmi Solutions, LLC --
    emmi in the sequel). Clicking on the appropriate "personalized code" button landed on a sparse webpage that demanded my date of birth (DOB), so I
    stopped.

    Being about COVID-19, and associated with UCSF, this seems to be nice
    example of the counterpart of a typical RISK: the legitimate email/website causes more harm than if they were malicious!

    To wit:

    (1) The DOB requirement in the emmi landing page is a red flag, so many
    *recipients will refrain from going further and actually receiving the
    information* (like I did).

    (2) The style and content of the email message *train recipients into
    vulnerability to malicious emails/websites,* by exposing them to red flags
    that turn out to be harmless.

    Red flags include:

    (i) Design language (if we can call it that!) / *branding inconsistent with
    the UCSF branding* - looks as if someone pasted a logo on something
    designed in 2005;

    (ii) The *URLs contained in the email *lie*: the button says startemmi.com,
    but actually links to my-emmi.com. ("my-ucsf.com", anyone?)

    (iii) I found no mention of this email campaign or emmi resources of in the
    UCSF COVID-19 page <https://coronavirus.ucsf.edu/>; *the emmi webpage
    looks unrelated to UCSF.

    (iv) the aforementioned DOB requirement at the emmi landing page.

    (3) The campaign *unnecessarily enables emmi to associate DOBs with IP and
    MAC addresses* (at least). Why is this necessary? This *undermines trust
    patients have in UCSF.

    (4) By allowing emmi to collect DOBs, the campaign exposes emmi and through
    emmi UCSF, and importantly, recipients of the email, aka UCSF* patients,
    to* the risk of *unauthorized disclosures of personally identifiable data
    (PII). Given the association of email address to the specific code, there
    is a strong likelihood the information matched via the website landing
    includes a lot more PII and is stored by emmi.

    Subject: Efficacy of location surveillance

    Having seen the reality of the app proposed for our [UK] NHS, and the great distance between our public health folks' assumptions and those of assorted tech companies and academics proposing private contact tracing, I blogged
    about the issue:

    https://www.lightbluetouchpaper.org/2020/04/12/contact-tracing-in-the-real-world/

    The time for contact tracing is past, for this wave. If we're going to use
    it next wave then the 5,000 public-health officers on the UK local
    government payroll won't be anything like enough. But we have a couple of million people being paid by the government to do nothing. If we follow the South Korean / Taiwanese example we'll want to start training lots of
    them. It's important not to distract policymakers from that decision by offering techno-magical promises on which we cannot deliver.

    There have recently been several proposals for pseudonymous contact tracing, including from Apple and Google. To both cryptographers and privacy
    advocates, this might seem the obvious way to protect public health and
    privacy at the same time. Meanwhile other cryptographers have been pointing
    out some of the flaws.

    There are also real systems being built by governments. Singapore has already deployedand open-sourced one that uses contact tracing based on bluetooth beacons. Most of the academic and tech industry proposals follow this strategy, as the *obvious* way
    to tell who's been within a few metres of you
    and for how long. The UK's National Health Service is working on one too,
    and I'm one of a group of people being consulted on the privacy
    and security. [...]

    The role of the ICANN community, Board, and organization in maintaining a secure, stable, and unified Internet has always been important, but at this time, when reliance on the Internet has skyrocketed, our collective role has become all the more vital. ICANN's mission frames our concern about cybercriminals who are exploiting the pandemic by perpetrating scams and victimizing Internet users. Some are selling phony cures, treatments, and vaccines. Some are using domain names as part of their efforts to prey on people at this time when many are experiencing anxiety, fear, and

    'Weitzner said the Bluetooth concept works by identifying proximity, not location. "We don't need to know where you were close to someone, just that
    you were close to someone," he said."'

    Common wisdom says that 'close' only counts for horseshoes and tossing hand grenades.

    Pandemic contact tracing, and proximity notification alerts, relies on human civility and restraint. People are timorous, and on high-alert given
    community spread potential. While social distancing protocols are generally deployed and enforced, there's little risk of a riot.

    A crowd of people protesting lock-down or other confinement restriction who receive a proximity alert notification, given COVID-19 serological test
    latency or a false-positive test result, might turn ugly very quickly.

    Walls, Shoes (Typer Durden)

    Tyler Durden, ZeroHedge, 13 Apr 2020 <https://www.zerohedge.com/geopolitical/new-cdc-study-shows-coronavirus-can-survive-hours-floors-walls-shoes>

    A preview of a new study: <https://wwwnc.cdc.gov/eid/article/26/7/20-0885_article> by the US Centers
    for Disease Control and Prevention - the CDC, for short - released last
    night offers some distressing news for health-care workers, as well as their families, partners and friends: New research suggests that nurses, doctors
    and others can track the virus out of the ward and into another - perhaps a more public, or less well-protected - environment, helping to spread the disease in a new way that public health officials haven't really considered.

    The study, entitled "Aerosol and Surface Distribution of Severe Acute Respiratory Syndrome Coronavirus 2 in Hospital Wards, Wuhan, China, 2020",
    was conducted in two wards at Wuhan's Huoshenshan Hospital by large team of Chinese researchers back in February and March. Though the team insisted
    that "respiratory droplets and close contact" remain the primary vectors for the disease, the possibility for hospital workers to transmit the virus on their shoes and clothes wasn't really well understood, until now.

    And unfortunately, if the data are confirmed, it would suggest that wards
    where coronavirus patients are treated are literally crawling with the
    virus, placing these health-care workers at extremely high risk for
    infection.

    According to the research, "94% of swabs taken from the ICU floor and 100%
    of swabs taken from one of the general wards used to treat patients with
    severe symptoms tested positive for coronavirus."

    Here's a summary of the research that describes how the GW and ICU were
    found to have the highest levels of the virus present on the floors and
    walls, as well as in the air. The rate of positivity was higher for the ICU than the GW, which makes sense.

    Even samples taken from the floor in the nearby hospital pharmacy showed
    'weak positive' for the virus. Patients are not allowed in the pharmacy, meaning there's only one way the samples could have gotten there.

    From February 19 through March 2, 2020, we collected swab samples from potentially contaminated objects in the ICU and GW as described
    previously. The ICU housed 15 patients with severe disease and the GW housed
    24 patients with milder disease. We also sampled indoor air and the air
    outlets to detect aerosol exposure. Air samples were collected by using a
    SASS 2300 Wetted Wall Cyclone Sampler at 300 L/min for of 30 min. We used sterile premoistened swabs to sample the floors, computer mice, trash cans, sickbed handrails, patient masks, personal protective equipment, and air outlets. We tested air and surface samples for the open reading frame (ORF)
    1ab and nucleoprotein (N) genes of SARS-CoV-2 by quantitative real-time PCR.

    Almost all positive results were concentrated in the contaminated areas (ICU 54/57, 94.7%; GW 9/9, 100%); the rate of positivity was much higher for the
    ICU (54/124, 43.5%) than for the GW (9/114, 7.9%) (Tables 1, 2). The rate of positivity was relatively high for floor swab samples (ICU 7/10, 70%; GW
    2/13, 15.4%), perhaps because of gravity and air flow causing most virus droplets to float to the ground. In addition, as medical staff walk around
    the ward, the virus can be tracked all over the floor, as indicated by the
    100% rate of positivity from the floor in the pharmacy, where there were no patients. Furthermore, half of the samples from the soles of the ICU medical staff shoes tested positive. Therefore, the soles of medical staff shoes
    might function as carriers. The 3 weak positive results from the floor of dressing room 4 might also arise from these carriers. We highly recommend
    that persons disinfect shoe soles before walking out of wards containing COVID-19 patients.

    The authors suggested that "air flow" and the forces of gravity might be responsible for moving the samples to the floors and the walls.But this certainly doesn't bode well for anybody arguing that the subway and
    restaurants will be able to go quickly back to normal, since an asymptomatic diner can leave the virus at their table for the next customer to pick up
    even if the table sits empty for hours - or even overnight.

    Governments worldwide are using digital surveillance technologies to track
    the spread of the coronavirus pandemic, raising concerns about the erosion
    of privacy. Many Asian governments are tracking people through their
    cellphones to identify those suspected of being infected with COVID-19,
    without prior consent. European countries are tracking citizens' movements
    via telecommunications data that they claim conceals individuals'
    identities; American officials are drawing cellphone location data from
    mobile advertising firms to monitor crowds, but not individuals. The biggest privacy debate concerns involuntary use of smartphones and other digital
    data to identify everyone with whom the infected had recent contact, then testing and quarantining at-risk individuals to halt the further spread of
    the disease. Public health officials say surveillance will be necessary in
    the months ahead, as quarantines are relaxed and the virus remains a threat while a vaccine is developed. https://orange.hosting.lsoft.com/trk/click?ref=3Dznwrbbrs9_6-24c74x221a65x068377&

    EXCERPT:

    The purpose of this FEMA page is to help the public distinguish between
    rumors and facts regarding the response to coronavirus (COVID-19) pandemic. Rumors can easily circulate within communities during a crisis.

    Do your part to the stop the spread of disinformation by doing three easy things:

    1. Don't believe the rumors.
    2. Don't pass them along.
    3. Go to trusted sources of information to get the facts about the
    federal (COVID-19) response.

    Always go to trusted sources of information like coronavirus.gov or your
    state and local government's official websites or social media accounts
    for instructions and information specific to your community.

    For more information on the coronavirus, please visit coronavirus.gov <https://www.coronavirus.gov/>. You can also visit our coronavirus
    (COVID-19) response <https://www.fema.gov/coronavirus> page for more updates

    So I just got a robot call from the NYC Department of Health in regards to C-19.

    Aside from the misleading info in it, and no way to ask it to "repeat", and lots of fadeouts...

    T-Mobile flagged it as a "scam likely".

    Yes. Really

    Subject: Error rates and CoVID-19 antibody tests

    In security, we know that there are errors that are false positives, and
    errors that are false negatives, and that both can create problems.

    At the moment, everybody is eagerly looking forward to serology tests for CoVID-19. These are tests (usually blood tests) that determine if you have antigens or antibodies related to defence against the SARS-CoV-2 virus.

    At least, they *try* to determine that. Because, well, errors.

    A good article on this is available at NPR. https://www.npr.org/sections/health-shots/2020/04/15/834497497/antibody-tests- for-coronavirus-can-miss-the-mark

    If you want the tl:dr version:

    If the test has 99% specificity, and you live in an area where only 1% of
    the population is actually infected, then when you get a "positive" test,
