... a novel public health concept. They were implemented for the first time in China in February, 2020, to tackle the coronavirus disease 2019 (COVID-19) outbreak. The Fangcang shelter hospitals in China were large-scale, temporary hospitals, rapidly built by converting existing public venues, such as stadiums and exhibition centres, into health-care facilities. They served to isolate patients with mild to moderate COVID-19 from their families and communities, while providing medical care, disease monitoring, food, shelter, and social activities.

Vitamin D supplementation recommended to help fight COVID-19 in Ireland
'Epidemiological studies, including several meta-analyses, have shown that people with low vitamin D levels have a higher risk of acute respiratory tract infection and community-acquired pneumonia. While these data do not necessarily infer causality, multiple molecular mechanisms have been identified by which vitamin D deficiency impairs resistance to viral respiratory tract infection. There are also a significant number of studies, including several meta-analyses, which have indicated that vitamin D supplementation may reduce the likelihood of acute respiratory tract infection, and decrease its severity and duration where such infection does occur. These respiratory tract infections may include Covid-19. Proposed Protective Mechanisms against Covid-19: In this regard, vitamin D supplementation has been shown to suppress CD2614, a cell surface receptor which is thought to facilitate entry of the Covid-19 virus into the host cell. There is also good evidence that enhanced vitamin D status may protect against the critical immunological sequelae which are thought to elicit poorer clinical outcome in Covid-19 infection. These include prolonged interferon-gamma response, and persistent interleukin 6 elevation, a negative prognostic indicator in acutely-ill pneumonia patients, including those with Covid-19.'

COVID-19 and the NHS—“a national scandal” - The Lancet
Bloody hell, the UK is heading for a disaster. 'The NHS has been wholly unprepared for this pandemic. It's impossible to understand why. Based on their modelling of the Wuhan outbreak of COVID-19, Joseph Wu and his colleagues wrote in The Lancet on Jan 31, 2020: “On the present trajectory, 2019-nCoV could be about to become a global epidemic…for health protection within China and internationally…preparedness plans should be readied for deployment at short notice, including securing supply chains of pharmaceuticals, personal protective equipment, hospital supplies, and the necessary human resources to deal with the consequences of a global outbreak of this magnitude.” This warning wasn't made lightly. It should have been read by the Chief Medical Officer, the Chief Executive Officer of the NHS in England, and the Chief Scientific Adviser. They had a duty to immediately put the NHS and British public on high alert. February should have been used to expand coronavirus testing capacity, ensure the distribution of WHO-approved PPE, and establish training programmes and guidelines to protect NHS staff. They didn't take any of those actions. The result has been chaos and panic across the NHS. Patients will die unnecessarily. NHS staff will die unnecessarily. It is, indeed, as one health worker wrote last week, “a national scandal”. The gravity of that scandal has yet to be understood.'

new paper from the Imperial College COVID-19 epidemiological team: 'Following the emergence of a novel coronavirus (SARS-CoV-2) and its spread outside of China, Europe is now experiencing large epidemics. In response, many European countries have implemented unprecedented non-pharmaceutical interventions including case isolation, the closure of schools and universities, banning of mass gatherings and/or public events, and most recently, widescale social distancing including local and national lockdowns. In this report, we use a semi-mechanistic Bayesian hierarchical model to attempt to infer the impact of these interventions across 11 European countries. Our methods assume that changes in the reproductive number – a measure of transmission - are an immediate response to these interventions being implemented rather than broader gradual changes in behaviour. Our model estimates these changes by calculating backwards from the deaths observed over time to estimate transmission that occurred several weeks prior, allowing for the time lag between infection and death.'

Notes from the front lines in Italy: 'The current emergency allows exceptions to the use of not certified medical devices, if it is proved that no certified choices are available and in accordance with the local ethical committee. Furthermore, due to the short time required for the production, it is not possible to run extensive testing campaigns on the components, but each [additive manufacturing] operator must pay attention to the selection of materials and technologies that are suitable for the specific application, considering the risk classification of the components and the operational environment. In the following we summarize the workflow we applied at 3D4Med (http://www.3d4med.eu) – the Clinical 3D Printing Laboratory of San Matteo Hospital in Pavia – and Protolab – its engineering counterpart – to produce some of the requested components, along with some practical examples.'

What happened with the UK's "herd immunity" COVID-19 strategy
"I'll tell you what happened in the UK. Over the past decade, eminent figures in public health developed complex models that would help inform the UK response to a pandemic. The response plan would allow slow spread through a population and a number of deaths that would be deemed acceptable in relation to low economic impact. Timing of population measures such as social distancing would be taken, not early, but at a times deemed to have maximal psychological impact. Measures would be taken that could protect the most vulnerable, and most of the people who got the virus would hopefully survive. Herd immunity would beneficially emerge at the end of this, and restrictions could relax. This was a ground-breaking approach compared to suppressing epidemics. It was an approach that could revolutionise the way we handled epidemics. Complex modelling is a new science, and this was cutting edge. But a model is only ever as good as the assumptions you build it upon. The UK plan was based on models with an assumption that any new pandemic would be like an old one, like flu. And it also carried a huge flaw - there was no accounting for the highly significant variables of ventilators and critical care beds that are key to maintaining higher survival numbers." Amazing. The sheer arrogance and hubris of assuming the model was right! Somebody will have to pay for this, it's shocking.

Maciej Ceglowski asks for a massive surveillance program to defeat COVID-19.
However, as I mentioned on twitter -- there IS an alternative, privacy-preserving approach, which is what is being done in Singapore with their TraceTogether app.
In summary, everyone carries a phone running an app which has an anonymized a random ID, scans local Bluetooth periodically for other people's apps with their random IDs, and records them locally (not uploading to a server). If you find out you have COVID-19 you then trigger an upload of your contact history to a central server. That server then broadcasts out the list of IDs, and everyone you've been in contact with will then get a ping on their app to get tested, self-isolate, etc.
No central surveillance, no creepy big brother watching your location.
My pinboard has a few more write-ups on basically the same idea from various other places, including MIT. This is similar to what China's app does, but (as far as I can tell) with more privacy.
It looks like the Singaporean government digital services team behind TraceTogether is putting together an open source version, at Bluetrace.io.
IMO we have to do this or we will never get out of COVID-19 lockdown before 2021. I am massively in favour of adopting this approach in Ireland and across the world.

We Need A Massive Surveillance Program (Idle Words)
The most troubling change this project entails is giving access to sensitive location data across the entire population to a government agency. Of course that is scary, especially given the track record of the Trump administration. The data collection would also need to be coercive (that is, no one should be able to opt out of it, short of refusing to carry a cell phone). [...] But the public health potential of commandeering surveillance advertising is so great that we can’t dismiss it out of hand. I am a privacy activist, typing this through gritted teeth, but I am also a human being like you, watching a global calamity unfold around us. What is the point of building this surveillance architecture if we can't use it to save lives in a scary emergency like this one?

What’s the Evidence on Face Masks? What You Heard Was Probably Wrong
According to research on the SARS epidemic, face masks were the most consistently effective intervention for reducing the contraction and spread of SARS. In a Cochrane Review on the subject, 6 out of 7 studies showed that face masks (surgical and N95) offered significant protection against SARS. Hand washing was also very effective, supported by 4 out of 7 studies in a multivariate analysis. Although most of the studies in the Cochrane Review were on medical workers in a hospital setting, one study followed community transmission of SARS in Beijing. It found that consistently wearing a mask in public was associated with a 70% reduction in risk of catching SARS. Additionally, the authors of the paper noted that most people in the community wore simple surgical masks, not N95 respirators.

Rapidly manufactured ventilator system specification - GOV.UK
This is a specification of the minimally (and some preferred options) clinically acceptable ventilator to be used in UK hospitals during the current SARS-CoV2 outbreak. It sets out the clinical requirements based on the consensus of what is ‘minimally acceptable’ performance in the opinion of the anaesthesia and intensive care medicine professionals and medical device regulators. It is for devices, which are most likely to confer therapeutic benefit on a patient suffering with ARDS caused by COVID-19, used in the initial care of patients requiring urgent ventilation. A ventilator with lower specifications than this is likely to provide no clinical benefit and might lead to increased harm, which would be unacceptable for clinicians and would, therefore, not gain regulatory approval.

'PPE (Personal Protection Equipment) is critical to the protection of healthcare workers, acting as a barrier and therefore controlling exposure to COVID-19. Some of the most fundamental items comprising PPE include gloves, goggles, surgical masks, respirators, protective gowns, and disinfectant. Many of these crucial PPE items are now in short supply due to interruptions in the supply chain, and also from the massive demand as the number of patients infected continues to grow exponentially. Numerous medical devices are required to treat the COVID-19 patient and will also fall into short supply (e.g. ventilators). Shortages of necessary PPE and medical devices will continue to pose a significant problem for healthcare workers and patients around the globe.'

This is absolutely appalling behaviour. People are dying -- free the blueprints!
A medical device manufacturer has threatened to sue a group of volunteers in Italy that 3D printed a valve used for life-saving coronavirus treatments. The valve typically costs about $11,000 from the medical device manufacturer, but the volunteers were able to print replicas for about $1 (via Techdirt). A hospital in Italy was in need of the valves after running out while treating patients for COVID-19. The hospital’s usual supplier said they could not make the valves in time to treat the patients, according to Metro. That launched a search for a way to 3D print a replica part, and Cristian Fracassi and Alessandro Ramaioli, who work at Italian startup Isinnova, offered their company’s printer for the job, reports Business Insider. However, when the pair asked the manufacturer of the valves for blueprints they could use to print replicas, the company declined and threatened to sue for patent infringement, according to Business Insider Italia. Fracassi and Ramaioli moved ahead anyway by measuring the valves and 3D printing three different versions of them.

China have enforced a variety of measures aimed at social distancing including lockdowns, restrictions on movement and cordon-sanitaires, as well as the Alipay Health Code smartphone application (an add on to the WeChat app system) now adopted in over 200 cities and by 90% of individuals in one Chinese province. A separate system has been implemented in South Korea, and both have come under public scrutiny over issues of data protection and privacy. We sought to design a broadly acceptable version of this platform, leveraging commonly used smartphone functionality. This system is currently in development, and based on a very simple algorithm, that we show through mathematical modelling will enable public health agencies to prevent a COVID-19 epidemic while minimizing social and economic disruption.

COVID-19 has a relatively long infectious incubation period, averaging five days but potentially up to two weeks, during which there may be asymptomatic transmission. In other words, there may be a period of time in which people who carry COVID-19 don't necessarily show symptoms and may not even realise they are infected, but are still capable of infecting others. This makes it harder for health professionals and epidemiologists to trace who has come into contact with infected persons ('contact tracing'), which in turn makes the virus more difficult to effectively contain. Many people, however, now carry GPS-enabled smartphones which already track their location over time - most mapping apps, like Google Maps or MapQuest, already collect this data by default. We believe that this information could be used to rapidly and automatically perform a type of contact tracing, helping limit the spread of COVID-19 and other infectious diseases. These phones are usually also Bluetooth-enabled, allowing them to track and record which other phones they're in proximity to. We believe that together, these two pieces of information can be used to inform and empower our users in a range of ways. Firstly, we can generate heatmaps of high-risk areas from demographic data, known cases, and epidemiological modelling, allowing users to adjust their behaviour accordingly. Secondly, we can use Bluetooth connections between users to enact cryptographically secure contact tracing and alerting them if we learn that they have been exposed to COVID-19, without revealing the identities or infection status of any other users.

Good to know. This is testing against a H1N1 flu virus, but hopefully applies for COVID-19 too.
... Rapid treatment of the virus with hot water had little effect on the virus, reducing the titre by around two-fold, but prolonged incubation at 55°C abolished detectable infectivity. However, the addition of any of 1% bleach, 50% and 10% malt vinegar and 1%, 0.1% and 0.01% washing up liquid were all effective at rapidly reducing viable virus below the limit of detection, while a low concentration of vinegar (1%) was no more effective than hot water alone (Figure 1A). In contrast to the plaque assay results, most agents were ineffective at reducing the number of detectable genome copies as determined by RT-PCR, with only bleach having a significant effect (Figure 2A). The data for the plaque assays and RT-PCR assays are compiled in Tables S1 and S2. Thus, while a strong oxidizing agent such as bleach is effective at reducing both genome detection and virus infectivity, low pH and detergent are equally efficacious virucidal agents. These results also indicate that whilst vinegar and detergent disrupt the viral envelope proteins reducing infectivity, only bleach disrupts the viral genome.

Unpleasant stuff:
A week ago, Italy had so few cases of corona that it could give each stricken patient high-quality care. Today, some hospitals are so overwhelmed that they simply cannot treat every patient. They are starting to do wartime triage. Here’s the guidance for that.

Trees on commercial UK plantations 'not helping climate crisis'
“There is no point growing a lot of fast-growing conifers with the logic that they sequester carbon quickly if they then go into a paper mill because all that carbon will be lost to the atmosphere within a few years,” said Thomas Lancaster, head of UK land policy at the Royal Society for the Protection of Birds (RSPB), which commissioned the report. “We should not be justifying non-native forestry on carbon grounds if it’s not being used as a long-term carbon store.”
Absolutely. Commercial forestry is not going to help address the climate change problem.(tags: business economics environment climate-change forestry trees coillte)
low-cost mechanical ventilator prototype
a team of students from MIT has devised a better way to keep patients breathing in places that lack standard mechanical ventilators, or during times of emergency such as pandemics or natural disasters, when normal hospital resources may be overextended. They have designed a system that uses the same widely available manual pump — the same type used for the farmer in India. The new system encases the pump in a plastic box with a battery, motor and controls to take the place of the manual compression process.
This article from 2010 notes 'a U.S. government study in 2005 found that in a worst-case pandemic scenario, this country alone might need more than 700,000 mechanical ventilators, while only 100,000 are now in use.'(tags: ventilators covid-19 breathing healthcare hardware mit ambu-bag)
Testimony of a surgeon working in Bergamo, in the heart of Italy's coronavirus outbreak : medicine
Terrifying:
After thinking for a long time if and what to write about what's happening here, I felt that silence was not responsible. I will therefore try to convey to lay-people, those who are more distant from our reality, what we are experiencing in Bergamo during these Covid-19 pandemic days. I understand the need not to panic, but when the message of the danger of what is happening is not out, and I still see people ignoring the recommendations and people who gather together complaining that they cannot go to the gym or play soccer tournaments, I shiver. I also understand the economic damage and I am also worried about that. After this epidemic, it will be hard to start over.

We’re learning a lot about the coronavirus. It will help us assess risk
Early studies on Covid-19 suggest people who have contracted the coronavirus are emitting, or “shedding,” infectious viruses very early on — in fact sometimes even before they develop symptoms. “We do know from shedding studies that people can shed in the pre-symptomatic phase,” Van Kerkhove said, adding that while the data are still preliminary “it seems that people shed more in the early phases rather than the late phases of disease.”

The Bulletin of the Atomic Scientists on nuclear power plant risks
The Japan Center for Economic Research, a source sympathetic to nuclear power, recently put the long-term costs of the 2011 Fukushima accident as about $750 billion. [...] The main public risk of nuclear power plants comes from rare but devastating nuclear accidents. Because data on such accidents is sparse, the probability of their occurrence has to be calculated on the basis of a model, rather than obtained from experience. Moreover, the extent of an accident and its monetary consequences are postulated on the basis of models that are limited by analysts’ imagination. Who would have imagined, for example, that the Fukushima accident would involve several reactors? Or that Japan would subsequently shut down all its other nuclear power plants?

The history of leaded gasoline is nuts
It is frankly shocking that this was ignored for so long! "The history of leaded gasoline is nuts. Scientists warned it was poison, the factory where it was made was making workers loopy, but GM/Standard Oil enlisted the surgeon general to convince everyone it was safe and rejected alternatives. Massive public harm resulted." "A Yale physiologist named Yandell Henderson had tested tetraethyl lead as a potential nerve agent during WWI, and when asked his thoughts on putting it into gasoline, he reacted with alarm. 'Widespread lead poisoning was almost certain to result.' Later he deemed it the 'single greatest question in the field of public health that has ever faced the American public.'"

When Bloom filters don't bloom
A good exploration into modern CPU/memory performance behaviour, and profiling same on Linux using "perf stat -d" and "google-perftools":
Modern CPUs are really good at sequential memory access when it's possible to predict memory fetch patterns (see Cache prefetching). Random memory access on the other hand is very costly. Advanced data structures are very interesting, but beware. Modern computers require cache-optimized algorithms. When working with large datasets, not fitting L3, prefer optimizing for reduced number loads, over optimizing the amount of memory used. I guess it's fair to say that Bloom filters are great, as long as they fit into the L3 cache. The moment this assumption is broken, they are terrible. This is not news, Bloom filters optimize for memory usage, not for memory access. For example, see the Cuckoo Filters paper.

Connectivity at the origins of domain specificity in the cortical face and place networks | PNAS
Wow, this is cool -- babies are born with some "pre-wired" visual connectivity networks, specifically for faces and scenes:
Where does knowledge come from? We addressed this classic question using the test cases of the cortical face and scene networks: two well-studied examples of specialized “knowledge” systems in the adult brain. We found that neonates already show domain-specific patterns of functional connectivity between regions that will later develop full-blown face and scene selectivity. Furthermore, the proto face network showed stronger functional connectivity with foveal than with peripheral primary visual cortex, while the proto scene network showed the opposite pattern, revealing that these networks already receive differential visual inputs. Our findings support the hypothesis that innate connectivity precedes the emergence of domain-specific function in cortex, shedding new light on the age-old question of the origins of human knowledge.

Why Some COVID-19 Cases Are Worse than Others
For reasons that aren’t entirely clear, some people—especially the elderly and sick—may have dysfunctional immune systems that fail to keep the response to particular pathogens in check. This could cause an uncontrolled immune response, triggering an overproduction of immune cells and their signaling molecules and leading to a cytokine storm often associated with a flood of immune cells into the lung. “That’s when you end up with a lot of these really severe inflammatory disease conditions like pneumonia, shortness of breath, inflammation of the airway, and so forth.”

Heavy-duty electric truck driver ditches diesel
This is significant news -- sounds like electrified heavy trucks are well on the way:
When it is time to accelerate, the eCascadia’s single gear provides immediate power. That matters during all-too-frequent slowdowns on California freeways. When traffic begins moving, Williams keeps pace. In a diesel, he would be left behind, working through gears to get up to speed. “I would have the space of two diesel trucks in front of me. By the time I get going, five cars jump in front of me,” he said. “With this truck, I can stay right with the cars rather than being dropped back every time we stop and go.” Even with the truck restricted to 60 mph, Williams said he can shave 15 minutes off the drive from the ports to Chino in heavy traffic. With advanced driver assistance systems (ADAS) like adaptive cruise control, which keeps his truck at a set distance from the vehicle in front of him, and automatic emergency braking, Williams also drives a safer truck.

This is very persuasive and I'd have to agree.
Email is unsafe and cannot be made safe. The tools we have today to encrypt email are badly flawed. Even if those flaws were fixed, email would remain unsafe. Its problems cannot plausibly be mitigated.
Key point: this isn't (just) about PGP or SMTP, it's email as a whole system:The least interesting problems with encrypted email have to do with PGP. [...] But that’s a whole other argument. Even after we replace PGP, encrypted email will remain unsafe. Here's why: If messages can be sent in plaintext, they will be sent in plaintext. Metadata is as important as content, and email leaks it. Every archived message will eventually leak. Every long term secret will eventually leak.

A deepfake of the president of India’s ruling Bharatiya Janata Party (BJP), Manoj Tiwari, went viral on WhatsApp in the country earlier this month, ahead of legislative assembly elections in Delhi, according to Vice. It’s the first time a political party anywhere has used a deepfake for campaigning purposes. In the original video Tiwari speaks in English, criticizing his political opponent Arvind Kejriwal and encouraging voters to vote for the BJP. The second video has been manipulated using deepfake technology so his mouth moves convincingly as he speaks in Haryanvi, the Hindi dialect spoken by the target voters for the BJP.

A joint investigation from CORRECTIV and Frontal21 reveals how the American Heartland Institute is supporting climate change deniers in Germany with the goal of undermining climate protection measures:
Throughout the next half hour, Taylor shares the inner workings of his disinformation toolbox. He believes that Mathias, the PR agent sitting opposite him, wants to help his clients funnel cash into the intricate network of climate change deniers. Taylor explains how he is able to raise awareness of topics in exchange for money, how people can make tax-deductible donations anonymously through a U.S. foundation, and how the Institute’s publications mimic the tone of the New York Times so obscure ideas are taken more seriously. He detailed how he intends to make a young YouTuber from Germany the star of climate denier, and how he works closely with German partners whose ideas are consistently cited by the AfD in the Bundestag. Then a few weeks later, Taylor will send an offer in writing. It is something like a strategy document for a PR campaign in Germany: A campaign that the public will not recognize for what it really is, making it even more effective. The goal: No more prohibitive climate laws. Diesel instead of electric cars, energy from coal instead of wind turbines, industry growth instead of environmental protection.

excellent letter to the editor of the Farmer's Journal regarding the IFA's climate-denialist stance
in full:
Dr Donal Murphy-Bokern M.Agr.Sc. (NUI), Kroge-Ehrendorf, Germany Dear Sir: I've been involved in reseach on diet, sustainable agriculture and climate change for 25 years. Having followed the public debate across Europe in that time, I can only describe the current debate about diet and greenhouse gas emissions in Ireland as hysterical. This hysteria started a year ago with the then Irish Farmers Association's president appearing to refer to the EAT Lancet Commission, which includes highly respected nutritionists from the Harvard School of Medicine, as "quacks masquerading as nutrition experts". This was followed by his condemnation of the Taoiseach for answering a question about his carbon footprint by stating an intention to moderate his consumption of red meat. No vegan-led campaign could have better drawn public attention to the links between diet and environment than the IFA's boorish and ignorant reflex reactions. The hysteria goes on. Now, just a year later, the IFA's chosen greenhouse gas "guru" reports that methane from farming should be treated differently to CO,, raising hopes of a get-out-of-jail card for cattle and sheep. Self-description as a guru does not invite the confidence of scientific peers and Dr Mitloehner's presentation, published by the IFA, reveals why he is as controversial as is widely reported. Methane's short-lived nature does not lead to the public policy outcomes that he implies it should with climate acquittal for ruminant production. He reduced discussion about the impact of livestock to one currency, which is carbon, and then misrepresented the valuation of that currency. Despite being a native of Germany, where most land not suitable for arable crops is under forest, he argued that marginal land in Ireland cannot be used for anything other than for keeping cattle and sheep. But what was most striking about the IFA's guru is how he worked the audience using rhetorical tricks more associated with demagogic politicians than science. This science denial included using the strawman fallacy, raising and then countering several bogus opposing arguments. Listening to him, one could be forgiven for believing that vegans have been protesting on the streets of Dublin threatening to interfere with the nation's food supplies. He used the classical conspiracy theory complete with a collective name for the conspirators: "destructors". He then drew on popular images of Ireland ("green and lush" and "happy cows") to ingratiate himself with the audience while making wild and poorly informed assumptions about the scope for carbon sequestration on Irish grassland, displaying a poor understanding of basic soil science. The IFA's stated purpose was the rebalancing of the public debate. Hosting a controversial US scientist who refers to those with views different to those of the IFA on these matters as "destructors" is hardly a promising way forward. The IFA seems to continue to take pride in caring little for the concerns and expectations of the wider society upon which the real long-term interests of its members ultimately depend. Their faux-militancy might go down well with some members, but it now risks presenting Irish farmers as environmental and social pariahs.

The false promise of “renewable natural gas”
RNG [renewable natural gas] can, depending on feedstock and circumstances, be low or even zero-carbon. Utilities argue that ramping up the production of RNG and blending it with normal natural gas in pipelines can reduce [greenhouse gases] faster and cheaper than electrifying buildings. By pursuing electrification, they say, regulators are pushing unnecessary cost hikes onto consumers. It would be nice for the utilities if this were true. But it’s not. RNG is not as low-carbon as the industry claims and its local air and water impacts are concentrated in vulnerable communities. Even if it were low-carbon and equitable, there simply isn’t enough of it to substitute for more than a small fraction of natural gas. And even if it were low-carbon, equitable, and abundant, it still wouldn’t be an excuse to expand natural gas infrastructure or slow electrification. It isn’t a close call. The research is clear: Especially in a temperate climate like California, RNG is not a viable alternative for decarbonizing buildings. It is a desperate bid by natural gas utilities to delay their inevitable decline. Policymakers would be foolish to fall for it.

Opinion: Why has the State invested €70m in a private company to look at our genetic data?
In the UK, the publicly-funded 100,000 Genomes Project is attempting to sequence 100,000 genomes from 85,000 NHS patients. It is a private company, owned by the Department of Health and Social Care, that partners with industry and has transparent policies in place on ethics, access to the genetic data and engagement with patients and the public. Ireland too has decided to invest in genomic medicine. Rather than ensure that this investment is in a manner that best serves the Irish public, €73.5 million was given to Genomic Medicine Ireland (GMI), a company owned by the Chinese pharmaceutical company WuXi with zero public ownership, to sequence the genomes of 400,000 Irish people. This investment has serious legal and ethical concerns that are likely to negatively impact genomic research in Ireland.

How the CIA used Crypto AG encryption devices to spy on countries for decades - Washington Post
The Crypto AG story returns to the headlines once more:
The operation, known first by the code name “Thesaurus” and later “Rubicon,” ranks among the most audacious in CIA history. “It was the intelligence coup of the century,” the CIA report concludes. “Foreign governments were paying good money to the U.S. and West Germany for the privilege of having their most secret communications read by at least two (and possibly as many as five or six) foreign countries.”
It is worth noting that Ireland was a victim to this snooping as well:During the sensitive Anglo-Irish negotiations of 1985, the NSA's British counterpart, GCHQ, was able to decipher the coded diplomatic traffic being sent between the Irish embassy in London and the Irish Foreign Ministry in Dublin. It was reported in the Irish press that Dublin had purchased a cryptographic system from Crypto AG worth more than a million Irish pounds. It was also reported that the NSA routinely monitored and deciphered the Irish diplomatic messages.

'A Log-Linear Histogram Data Structure for IT Infrastructure Monitoring, Heinrich Hartmann, Theo Schlossnagle, (Submitted on 17 Jan 2020). The circllhist histogram is a fast and memory efficient data structure for summarizing large numbers of latency measurements. It is particularly suited for applications in IT infrastructure monitoring, and provides nano-second data insertion, full mergeability, accurate approximation of quantiles with a-priori bounds on the relative error. Open-source implementations are available for C/lua/python/Go/Java/JavaScript.' The paper compares it against 'alternative data-structures which are employed in practice for aggregated quantile calculations: Prometheus Histograms, t-digest, [Gil Tene's] HDR Histograms, and DDSketches'

A minimalist dashboard style using horizon charts:
Horizon charts reduce vertical space without losing resolution. Larger values are overplotted in successively darker colors, while negative values are offset to descend from the top. As you increase the number of colors, you reduce the required vertical space [...] . By combining position and color, horizon charts improve perception: position is highly effective at discriminating small changes, while color differentiates large changes. To further increase data density, Cubism favors per-pixel metrics where each pixel encodes a distinct point in time. Cubism also includes thoughtful default colors by Cynthia Brewer.

How can data centers use 100% renewable electricity?
The first step has been to offset. This is followed by matching usage with like-for-like energy purchases somewhere. The final stage is direct consumption of locally generated renewables, either in real time or stored from recent generation. So the next time you see a tech company announcing a huge renewables project, you should look to see exactly what that mean and where that energy will really go. New renewables are good, but whether that energy is actually powering the company operations directly is another question.

Critical Bluetooth Vulnerability in Android (CVE-2020-0022) – BlueFrag
On Android 8.0 to 9.0, a remote attacker within proximity can silently execute arbitrary code with the privileges of the Bluetooth daemon as long as Bluetooth is enabled. No user interaction is required and only the Bluetooth MAC address of the target devices has to be known. For some devices, the Bluetooth MAC address can be deduced from the WiFi MAC address. This vulnerability can lead to theft of personal data and could potentially be used to spread malware (Short-Distance Worm). On Android 10, this vulnerability is not exploitable for technical reasons and only results in a crash of the Bluetooth daemon.

Health-Records Company Pushed Opioids to Doctors in Secret Deal - Bloomberg
This is APPALLING. holy crap.
To doctors opening patients’ electronic records across the U.S., the alert would have looked innocuous enough. A pop-up would appear, asking about a patient’s level of pain. Then, a drop-down menu would list treatments ranging from a referral to a pain specialist to a prescription for an opioid painkiller. Click a button, and the program would create a treatment plan. From 2016 to spring 2019, the alert went off about 230 million times. The tool existed thanks to a secret deal. Its maker, a software company called Practice Fusion, was paid by a major opioid manufacturer to design it in an effort to boost prescriptions for addictive pain pills -- even though overdose deaths had almost tripled during the prior 15 years, creating a public-health disaster. The software was used by tens of thousands of doctors’ offices.

Climate Change Could Force Millions of Americans to Flee the Coast. AI Predicts Where They'll Go
By the end of the century, sea level rise could force 13 million people to move away from the U.S. coasts. But it’s not just the coasts that will be affected—so will the places where those migrants end up. In a study published last week in PLOS One, researchers used artificial intelligence to predict where those places are. The findings could have huge value to people not only living on the coast, but the communities that may deal with an influx of climate refugees inland over the coming century. “Our findings indicate that everybody should care about sea-level rise, whether they live on the coast or not,” Bistra Dilkina, a Computer Science Assistant Professor at the University of Southern California who led the study, said in a statement.

Why cancer-spotting AI needs to be handled with care
“There’s this idea in society that finding more cancers is always better, but it’s not always true,” Adewole Adamson, a dermatologist and assistant professor at Dell Medical School, tells The Verge. “The goal is finding more cancers that are actually going to kill people.” But the problem is “there’s no gold standard for what constitutes cancer.” As studies have found, you can show the same early-stage lesions to a group of doctors and get completely different answers about whether it’s cancer. And even if they do agree that that’s what a lesion shows — and their diagnoses are right — there’s no way of knowing whether that cancer is a threat to someone’s life. This leads to overdiagnosis, says Adamson: “Calling things cancer that, if you didn’t go looking for them, wouldn’t harm people over their lifetime.” As soon as you do call something cancer, it triggers a chain of medical intervention that can be painful, costly, and life-changing. In the case of breast cancer, that might mean radiation treatments, chemotherapy, the removal of tissue from the breast (a lumpectomy), or the removal of one or both breasts entirely (a mastectomy). These aren’t decisions to be rushed. Overdiagnosis, he says, “is a problem for a lot of different cancers; for prostate, melanoma, breast cancer, thyroid. And if AI systems become better and better at finding smaller and smaller lesions you will manufacture a lot of pseudo-patients who have a ‘disease’ that won’t actually kill them.”

Kevin Beaumont is calling this 'totally out of control'; 'the quiet cover up by companies paying ransoms is creating advanced attackers operating at a skill and capability which are going to be very difficult to defend against':
We’ve seen 150 000 unique infections in the past 5 months. And a total of 148 samples together demanding more than 38 million dollars. Some of the attacks are on a huge scale, encrypting over 3000 unique systems in one attack. Some of these attacks where discussed in the news, but many companies remained silent. Keep in mind we have a limited visibility of all samples; we only extract samples from pastebin. For the infection traffic we don’t have visibility on samples that disable the C2 traffic. Next to this not every sample hits all of the c2 domains. All statistics shown in this blog are a subset of the total scale. The actual problem is even bigger than we can measure. [....] With the rise of more mature and big malicious business relaying on ransomware it is apparent that infosec plays crucial role. The most important step we as a security industry is secure offsite backups that are not removable from the network or using privileges acquired within the network. After that we can spend time actually securing our networks.

You want to reduce the carbon footprint of your food? Focus on what you eat, not whether your food is local:
For most foods – and particularly the largest emitters – most GHG emissions result from land use change (shown in green), and from processes at the farm stage (brown). Farm-stage emissions include processes such as the application of fertilizers – both organic (“manure management”) and synthetic; and enteric fermentation (the production of methane in the stomachs of cattle). Combined, land use and farm-stage emissions account for more than 80% of the footprint for most foods. Transport is a small contributor to emissions. For most food products, it accounts for less than 10%, and it’s much smaller for the largest GHG emitters. In beef from beef herds, it’s 0.5%. Not just transport, but all processes in the supply chain after the food left the farm – processing, transport, retail and packaging – mostly account for a small share of emissions.
Excellent graph from Our World In Data. tl;dr: beef is massively damaging in terms of emissions, poultry is far less, then fish, then various kinds of veg are at the low end. It's shocking how much impact beef has.(tags: co2 food data farming carbon emissions climate-change methane transport locavores)

Making a green internet with the Green Web Foundation
The tech sector is responsible for 2% to 4% of global emissions today. That’s less than all automobile transport, but roughly comparable to the global emissions of all shipping, or aviation. [....] The problem is that even as our electricity grids transition to more sustainable sources of energy, by dropping coal in favour of renewables, for instance, this doesn’t automatically mean we’re getting a much greener internet. That’s partly because the internet, while distributed around the world, is not evenly distributed. If you were to look at a map of all the major infrastructures of the internet, you’d see that it clusters around a number of geographic features. The reason behind this is that there is a cost, both in time and money, to move data around the world, and even though that cost dropped over time, the rate that we generate and use data for processing has grown faster than this cost has dropped. This creates incentives to increase the amount of infrastructure in a few places, rather than distribute it evenly. So, where we’ve previously seen data centres built in places with good access to fossil fuel energy, and in a regulatory environment that favours established fossil fuel industries over renewables, you’ll often see even more internet infrastructure being built, often using the same kinds of ‘grey’ power mixes. The best example of this is the Data Centre Alley in North Virginia, USA. Here, the county of Loudoun boasts that 70% of the world’s internet traffic passes through its digital infrastructure. With 13.5 million square feet of data centres in use, and another 4.5 million planned or developed, it’s the largest concentration of infrastructure in the world. Most of the power needed for this data centre comes from a single company, Dominion Energy, which runs a particularly dirty energy mix, with most of its energy coming from fracked gas, coal and nuclear power. Less than 5% comes from renewables, and this figure will barely pass 10% by 2030.

“Cyber Rambo”: How a US Army vet aided the right-wing coup in Bolivia
Twitter's turning out to be a shitfest of a platform:
Julián Macías Tovar, a social media coordinator for the Spanish left-wing party Podemos, analyzed the data from the hashtags and found that thousands of accounts were created in the days before the election and spiked after Bolivian military leaders called on Morales to resign. According to his data, 48,000 accounts were created in a matter of just four days to amplify the hashtags. Tovar also discovered that a single account contributed more than 13,000 retweets to the hashtags. The account belonged to US Army veteran Luis Suarez, who automated his account to retweet posts with the hashtags using a custom app. Data scientist Rubén Rodríguez Casañ similarly found that Suarez's account was able to retweet as many as 69 posts in a single second.

Historic S3 data corruption due to a fault load balancer
This came up in a discussion of using hashes for end-to-end data resiliency on the og-aws slack. Turns out AWS support staff wrote it up at the time:
We've isolated this issue to a single load balancer that was brought into service at 10:55pm PDT on Friday, 6/20 [2008]. It was taken out of service at 11am PDT Sunday, 6/22. While it was in service it handled a small fraction of Amazon S3's total requests in the US. Intermittently, under load, it was corrupting single bytes in the byte stream. When the requests reached Amazon S3, if the Content-MD5 header was specified, Amazon S3 returned an error indicating the object did not match the MD5 supplied. When no MD5 is specified, we are unable to determine if transmission errors occurred, and Amazon S3 must assume that the object has been correctly transmitted. Based on our investigation with both internal and external customers, the small amount of traffic received by this particular load balancer, and the intermittent nature of the above issue on this one load balancer, this appears to have impacted a very small portion of PUTs during this time frame. One of the things we'll do is improve our logging of requests with MD5s, so that we can look for anomalies in their 400 error rates. Doing this will allow us to provide more proactive notification on potential transmission issues in the future, for customers who use MD5s and those who do not. In addition to taking the actions noted above, we encourage all of our customers to take advantage of mechanisms designed to protect their applications from incorrect data transmission. For all PUT requests, Amazon S3 computes its own MD5, stores it with the object, and then returns the computed MD5 as part of the PUT response code in the ETag. By validating the ETag returned in the response, customers can verify that Amazon S3 received the correct bytes even if the Content MD5 header wasn't specified in the PUT request. Because network transmission errors can occur at any point between the customer and Amazon S3, we recommend that all customers use the Content-MD5 header and/or validate the ETag returned on a PUT request to ensure that the object was correctly transmitted. This is a best practice that we'll emphasize more heavily in our documentation to help customers build applications that can handle this situation.

Expert reaction to World Health Organisation Q&A on e-cigarettes
It does seem that scaremongering about vaping is hurting efforts to get people off cigarettes:
“Practically all the factual statements in it are wrong. There is no evidence that vaping is ‘highly addictive’ – less than 1% of non-smokers become regular vapers. Vaping does not lead young people to smoking – smoking among young people is at all time low. There is no evidence that vaping increases risk of heart disease or that could have any effect at all on bystanders’ health. The US outbreak of lung injuries is due to contaminants in illegal marijuana cartridges and has nothing to do with nicotine vaping. There is clear evidence that e-cigarettes help smokers quit. “The authors of this document should take responsibility for using blatant misinformation to prevent smokers from switching to a much less risky alternative.”

Facebook Ad Library Showed Just How Unreliable Facebook’s Security System For Elections Is
On Dec. 10, just two days before the United Kingdom went to the polls, some 74,000 political advertisements vanished from Facebook’s Ad Library, a website that serves as an archive of political and issue ads run on the platform. [....] Facebook has said it will not fact-check political ads or restrict the ability for campaigns to target people. Instead, it said it will provide transparency with tools like the Ad Library, the Ad Library report, and the Ad Library API, so the public, researchers, and journalists can monitor how elections play out on the platform. But that only works to the degree that those tools operate properly. It was only the news media’s reporting that brought the issue out into the open. “The fact that they could have an outage like this that went up to the day before an election, and they didn’t really publicly communicate,” Laura Edelson, a computer scientist at NYU whose work involves using the API, told BuzzFeed News, “that’s just not how you treat a security system. That’s what this is — this is a security system for elections.”

How is computer programming different today than 20 years ago?
Some good answers:
A desktop software now means a web page bundled with a browser. You are not officially considered a programmer anymore until you attend a $2K conference and share a selfie from there. Code must run behind at least three levels of virtualization now. Code that runs on bare metal is unnecessarily performant. Running your code locally is something you rarely do. A tutorial isn’t really helpful if it’s not a video recording that takes orders of magnitude longer to understand than its text. Mobile devices can now show regular web pages, so no need to create a separate WAP page on a separate subdomain anymore. We create mobile pages on separate subdomains instead. We run programs on graphics cards now. Since we have much faster CPUs now, numerical calculations are done in Python which is much slower than Fortran. So numerical calculations basically take the same amount of time as they did 20 years ago. Storing passwords in plaintext is now frowned upon, but we do it anyway.
There's also some serious answers, but I prefer these ones.(tags: evolution dev programming humour coding lols fortran history)

The Center Blows Itself Up: Care and Spite in the ‘Brexit Election’
The center of British politics has become a smoldering pit. The country is now being governed by a hard-right government placed in power by its oldest citizens, in the face of the active hatred of its increasingly socialist-inclined youth. It’s fairly clear that for the Johnson team, Brexit was never anything but an electoral strategy, and that they don’t have the slightest idea how to translate it into economic prosperity. (It is an unacknowledged irony of the current situation that the people most likely to profit from the Brexit process are, precisely, lawyers—and, probably secondarily, accountants. For everyone else, it’s hard to imagine a scenario where they will improve their current situation, and quite easy to imagine Johnson being remembered as one of the most disastrous prime ministers in British history.)

The “Smoky Cokey” cocktail tastes exactly how it sounds, and that’s a good thing
Via Ben -- here's a bunch of critics going nuts about a fecking whiskey and coke. 'The 'Smoky Cokey' [...] is a Coca-Cola that tastes smoky thanks to the addition of peaty scotch. Specifically, the drink as it was explained to me requires Lagavulin 16, a scotch that sells for around $75 a bottle in the United States. My god the critics go overboard with this: 'the rich smoke and intensity of Lagavulin is beautifully countered by the sweet vanilla and gentle spices of the cola' 'I actually like to make mine with Mexican Coke when I have one handy, because I find the extra sweetness works even better with the fairly aggressive peatiness of something like a Lagavulin' 'There’s something about the sherry notes present in the Lagavulin that makes it really sing when drowned in high fructose corn syrup' My theory is that this is a marketing wheeze devised by Diageo PR to garner a bit of clickbait....

Wow, this is a great paper recommendation from Adrian Colyer - 'Ironies of automation', Bainbridge, Automatica, Vol. 19, No. 6, 1983.
In an automated system, two roles are left to humans: monitoring that the automated system is operating correctly, and taking over control if it isn’t. An operator that doesn’t routinely operate the system will have atrophied skills if ever called on to take over. Unfortunately, physical skills deteriorate when they are not used, particularly the refinements of gain and timing. This means that a formerly experienced operator who has been monitoring an automated process may now be an inexeperienced one. Not only are the operator’s skills declining, but the situations when the operator will be called upon are by their very nature the most demanding ones where something is deemed to be going wrong. Thus what we really need in such a situation is a more, not a lesser skilled operator! To generate successful strategies for unusual situtations, an operator also needs good understanding of the process under control, and the current state of the system. The former understanding develops most effectively through use and feedback (which the operator may no longer be getting the regular opportunity for), the latter takes some time to assimilate.

Modin: Speed up your Pandas workflows by changing a single line of code
The modin.pandas DataFrame is an extremely light-weight parallel DataFrame. Modin transparently distributes the data and computation so that all you need to do is continue using the pandas API as you were before installing Modin. Unlike other parallel DataFrame systems, Modin is an extremely light-weight, robust DataFrame. Because it is so light-weight, Modin provides speed-ups of up to 4x on a laptop with 4 physical cores. We have focused heavily on bridging the solutions between DataFrames for small data (e.g. pandas) and large data. Often data scientists require different tools for doing the same thing on different sizes of data. The DataFrame solutions that exist for 1KB do not scale to 1TB+, and the overheads of the solutions for 1TB+ are too costly for datasets in the 1KB range. With Modin, because of its light-weight, robust, and scalable nature, you get a fast DataFrame at small and large data. With preliminary cluster and out of core support, Modin is a DataFrame library with great single-node performance and high scalability in a cluster.

SHA-1 is a Shambles - First Chosen-Prefix Collision on SHA-1 and Application to the PGP Web of Trust
Abstract: The SHA-1 hash function was designed in 1995 and has been widely used during two decades. A theoretical collision attack was first proposed in 2004 [WYY05], but due to its high complexity it was only implemented in practice in 2017, using a large GPU cluster [SBK+17]. More recently, an almost practical chosen-prefix collision attack against SHA-1 has been proposed [LP19]. This more powerful attack allows to build colliding messages with two arbitrary prefixes, which is much more threatening for real protocols. In this paper, we report the first practical implementation of this attack, and its impact on real-world security with a PGP/GnuPG impersonation attack. We managed to significantly reduce the complexity of collisions attack against SHA-1: on an Nvidia GTX 970, identical-prefix collisions can now be computed with a complexity of 261.2261.2 rather than 264.7264.7, and chosen-prefix collisions with a complexity of 263.4263.4 rather than 267.1267.1. When renting cheap GPUs, this translates to a cost of 11k US\$ for a collision, and 45k US\$ for a chosen-prefix collision, within the means of academic researchers. Our actual attack required two months of computations using 900 Nvidia GTX 1060 GPUs (we paid 75k US\$ because GPU prices were higher, and we wasted some time preparing the attack). Therefore, the same attacks that have been practical on MD5 since 2009 are now practical on SHA-1. In particular, chosen-prefix collisions can break signature schemes and handshake security in secure channel protocols (TLS, SSH). We strongly advise to remove SHA-1 from those type of applications as soon as possible. We exemplify our cryptanalysis by creating a pair of PGP/GnuPG keys with different identities, but colliding SHA-1 certificates. A SHA-1 certification of the first key can therefore be transferred to the second key, leading to a forgery. This proves that SHA-1 signatures now offers virtually no security in practice. The legacy branch of GnuPG still uses SHA-1 by default for identity certifications, but after notifying the authors, the modern branch now rejects SHA-1 signatures (the issue is tracked as CVE-2019-14855).

Algorithms interviews: theory vs. practice
Good critique of the current practice of using algorithm questions during tech interviews from Dan Luu
At this point, we've gone through a few decades of programming interview fads, each one of which looks ridiculous in retrospect. Either we've finally found the real secret to interviewing effectively and have reasoned our way past whatever roadblocks were causing everybody in the past to use obviously bogus fad interview techniques, or we're in the middle of another fad, one which will seem equally ridiculous to people looking back a decade or two from now. Without knowing anything about the effectiveness of interviews, at a meta level, since the way people get interview techniques is the same (crib the high-level technique from the most prestigious company around), I think it would be pretty surprising if this wasn't a fad. I would be less surprised to discover that current techniques were not a fad if people were doing or referring to empirical research or had independently discovered what works.

Power Line Adapter noise interference
oh dear, I use this model....
About 3 weeks ago our neighbour installed power line adapters. The PLAs in question were branded TP-Link [....] How did I know that my neighbour had installed these? Well, the 50MHz band was immediately submerged under a wall of radio noise. Much tinkering with the Noise Blanker settings on the Icom IC-7300 allowed me to separate out two distinct types of noise - 1st a sound like a chicken clucking which was there 24 hours per day and - 2nd a wideband swoosh of white noise of varying strength which happened at certain times.

City maps from tourists' feelings
This is fascinating, and potentially quite useful -- although the great loft I stayed in in Antwerp is marked in a decidedly yellowish region :) (via Nelson)
The aim of this project is to map tourists’ perceptions of different urban areas through data retrieved from vacation rental platform Airbnb. After their stay, Airbnb guests score their feeling about the neighbourhood using a star-based rating system. The aggregated rating of each Airbnb listing is publicly accessible, and given the widespread expansion of this platform, a large amount of data is available for the most visited cities. When overlaid on a map of the city, the data reveals interesting geographic patterns and exposes subjective perceptions on safety, upkeep or convenience. -- Beñat Arregi

Alice Goldfuss clarifies JK Rowling's "dress however you please" anti-trans comments
This was a really educational thread for me -- demonstrating how these phrases are a symptom, not support
JK Rowling hates trans people, but I want to talk a little bit about the *way* she hates them so you can recognize it in the wild. She says “Dress however you please” and “Call yourself whatever you like” At first glance it sounds supportive, but it isn’t It’s disengaging She is taking a very real and concrete issue (the acceptance of trans people as humans with full rights and respect in society), minimizing it to some surface level features (appearance and names), and then abdicating any responsibility She is purposefully mischaracterizing trans people as adults playing dress-up and then claiming to be fine with that...at a distance The language she uses is similar to language used to minimize gay people “You can kiss whoever you want behind closed doors!” It’s also similar to the old favorite “I don’t care if you’re black, white, or purple!” Purple people don’t exist, but now they’ve minimized the issue of racism and swept it away while claiming to be supportive All of these phrases add up to the same message: “I support you, as long as you don’t change my experiences or inconvenience me in any way.” And that’s not actual support

J.K. Rowling’s transphobia is a product of British culture
Good explainer on why the UK is so TERFy these days:
Trans-exclusionary radical feminist (TERF) ideology has been helped along in the UK by media under the leadership of Rupert Murdoch and the Times of London for years. Any vague opposition to gender-critical thought in the UK brings accusations of “silencing women” and a splashy feature or op-ed in a British national newspaper. Australian radical feminist Sheila Jeffreys went before the UK Parliament in March 2018 and declared that trans women are “parasites,” language that sounds an awful lot like Donald Trump speaking about immigrants. According to Heron Greenesmith, who studies the modern gender-critical movement as a senior research associate at the social-justice think tank Political Research Associates, gender-critical feminism in the UK grew out of a toxic mix of historical imperialism and the influence of the broader skeptical movement in the early aughts — which was hyperfocused on debunking “junk science” and any idea that considered sociological and historical influence and not just biology. Those who rose to prominence in the movement did so through a lot of “non-tolerant calling-out and attacking people,” Greenesmith said, much like gender-critical feminism. “Anti-trans feminists think they have science on their side. It is bananas how ascientific their rhetoric is, and yet literally they say, ‘Biology isn’t bigotry.’ In fact, biology has been used as bigotry as long as biology has been a thing.”

Opinion | Twelve Million Phones, One Dataset, Zero Privacy - The New York Times
'We identified people at political rallies and protests, in one case from 2016 we saw a Seattle-based Microsoft employee take a day off and visit Amazon's campus...when we found him on LinkedIn in 2019 he was an Amazon employee. Turns out his phone had given away his job interview. In recent months we’ve spoken with people we’ve found in the data. Their reaction is surprising — a blend of contradictory emotions like outrage and apathy. We don't have the language to talk about this stuff. And part of the reason is...we adopted this tech so fast. A big takeaway from my experience with this reporting: This is the decade we were brainwashed into surveilling ourselves. In just over 10 years we were sold a future of personalization and convenience and paid for it with little pieces of ourselves that we can never get back.'

Ex-US healthcare industry insider spills the beans on false "choice"
The truth, of course, is you have little "choice" in healthcare now. Most can’t keep their plan as long as they want, or visit any doctor or hospital. Some reforms, like Medicare For All, *would* let you. In other words, M4A actually offers more choice than the status quo. So if a politician tells you they oppose reforming the current healthcare system because they want to preserve "choice," either they don't know what they're talking about - or they're willfully ignoring the truth. I assure you, the insurance industry is delighted either way.

In The 2010s, We All Became Alienated By Technology
Looking back from the shaky edge of a new decade, it’s clear that the past 10 years saw many Americans snap out of this dream, shaken awake by a brutal series of shocks and dislocations from the very changes that were supposed to "create a civilization of the Mind in Cyberspace.” When they opened their eyes, they did indeed see that the Digital Nation had been born. Only it hadn’t set them free. They were being ruled by it. It hadn’t tamed politics. It sent them berserk. And it hadn’t brought people closer together. It had alienated them.

'Despite the growth of ethical frameworks, AI systems continue to be deployed rapidly across domains of considerable social significance—in healthcare, education, employment, criminal justice, and many others—without appropriate safeguards or accountability structures in place. Many urgent concerns remain, and the agenda of issues to be addressed continues to grow: the environmental harms caused by AI systems are considerable, from extraction of materials from our earth to the extraction of labor from our communities. In healthcare, increasing dependence on AI systems will have life-or-death consequences. New research also highlights how AI systems are particularly prone to security vulnerabilities and how the companies building these systems are inciting fundamental changes to the landscape of our communities, resulting in geographic displacement. Yet the movements of the past year give reason to hope, marked by a groundswell of pushback from both expected and unexpected places, from regulators and researchers to community organizers and activists to workers and advocates. Together, they are building new coalitions upon legacies of older ones, and forging new bonds of solidarity. If the past year has shown us anything, it is that our future will not be determined by the inevitable progress of AI, nor are we doomed to a dystopic future. The implications of AI will be determined by us—and there is much work ahead to ensure that the future looks bright.'
COP-25 Report from Prof. John Sweeney of An Taisce
Very negative review from COP-25. This is depressing:
There is no doubt but that the failure of COP25 is symptomatic of a world failing to advance the multilateralism ideals many of us grew up with. International cooperation in economics, politics and in solving environmental problems, such as ozone depletion, have now given way to narrow national and populist ideologies. What is most worrying about current developments in tackling climate change is however the disconnect between the power brokers and society at large. The advice of the scientists and the pleas of the young were ignored in Madrid. Indeed some 200 young people were summarily ejected from the conference after a protest, and the eloquent arguments presented by the young Irish activists at several side events fell on deaf ears. Attempts by some world leaders and some media commentators to direct personal vitriol against young activists even surfaced.

COP25 Ended in Failure. What’s the Way Forward?
over the last few months, I’ve found myself thinking a lot more about the model offered by the nuclear nonproliferation agreements forged between the U.S. and the Soviet Union in the late 1980s — the planet’s two superpowers reaching a kind of consensus about a global existential threat, taking significant (if not complete) steps to mitigate that risk, and then more or less bullying the rest of the world to follow suit. Climate change is a very different challenge, but policy negotiations to address it may nevertheless benefit from reducing the number of sides involved in a game-theory calculus from 186 (the number of nations party to the Paris accords) to just two (in this case, the U.S. and China). Of course, this would require not just a complete change of perspective on climate in Washington but some shift almost as complete in Beijing, where commitments made in 2019 to open new coal plants are sufficient on their own to eliminate the entire planet’s chances of staying below 1.5 degrees Celsius of warming.

The internet wasn’t the place for smart campaigning. The Labour party put out slick video after slick video, outspent the Tories on Snapchat and Facebook, and handed Jeremy Corbyn’s Twitter account to someone who understands memes extremely well for the entirety of election day. The Conservatives simply sat down and spent six weeks being wilfully stupid, and it worked. In fact, one of the few changes in strategy we saw in the online election was the Conservatives doubling down on simple and stupid. The opening of the campaign was marked by a “shitposting strategy”, with the Tory party sharing low-effort, banally funny campaign messages in the clear hope that they would get as much distribution from opponents as supporters. But, as the election went on, that approach was dropped in favour of a brutally simple one: pick three lines, whether or not they’re true, and just repeat them, for ever, on every platform, without shame or variation. Invent some Labour policies, make up a price-tag for them, and tweet it out as the cost of Labour. Make up a taxation strategy to pay for it, and tweet that out as the party’s tax bombshell. Endlessly, humourlessly, robotically come back to “get Brexit done”. There are lessons here for other political parties, but they aren’t pretty.

Trucks sent by the Queensland government carrying emergency supplies to the school, including Mount Tamborine bottled water, have been passing trucks heading in the opposite direction taking local water to bottling plants for beverage giants such as Coca-Cola. Water miners in the Mount Tamborine area supply roughly 130m litres of water each year to commercial bottling operations. Now the local bores are running dry.

A responsible entity would honestly and accurately address the real issues at hand, and would demonstrate that they've listened to communities beyond their own through their actions. On the other hand, an exploitative entity would pay lip service to the communities they affect while continuing to actively harm them. They would ramp up their launch schedule. They would continue to send up offensive, unaltered satellites while putting minimal effort into solving problems that have been raised. They would invite consultants, but would squash any objectionable voices. They would distort the truth about concerns that have been raised. They would put their business interests — such as lucrative potential government contracts — ahead of any human interests. And they would deflect criticism by running PR campaigns that draw attention away from the real issues.

Spain Might Be The World’s Most Important Climate Test | HuffPost UK
Can Spain get a Green New Deal enacted in the EU?
the Sánchez administration was forced to call another snap election last month. The Socialists again eked out a slim win, and this time agreed to form a coalition with Unidos Podemos, a party to its left. If Sánchez’s center-left vision of a Green New Deal could be criticized for not being ambitious enough, the inclusion of the anti-austerity Podemos could make the country the first to seriously attempt the kind of Green New Deal progressives elsewhere have laid out to curb soaring economic inequality and planet-heating emissions. Green New Dealers on both sides of the Atlantic argue that addressing both crises at once is key to staving off a resurgent neo-fascist right wing. Vox, a far-right party openly nostalgic for Franco-era Spanish authoritarianism, surged from zero to 24 parliamentary seats last April. November’s election brought that total to 52, making it the third-largest party in Spain. But, even with a new left flank in the governing coalition, experts say the chances of making transformative changes are slim, thanks to the European Union’s rules on spending and public ownership. It’ll be a test for how much effectively the Green New Deal can beat back the far right while still confined by what one researcher called the “straitjacket of austerity.”

Denmark adopts climate law to cut emissions 70% by 2030
Denmark’s parliament adopted a new climate law on Friday, committing to reach 70% below its 1990 emissions in the next eleven years. The law targets carbon neutrality by 2050 and includes a robust monitoring system. New legally-binding targets will be set every five years, with a ten-year perspective. The first of these will be set in 2020. In what the government claims is a first for a national legislature, the new law also has a commitment to climate engagement internationally. This includes an ongoing obligation to deliver on international agreements, including climate finance to developing countries.

Now Any Government Can Buy China’s Tools for Censoring the Internet
Well, this is grim:
“Autocracy as a service” lets countries buy or rent the technology and expertise they need, as they need it. It gets around the problem that being able to censor and surveil the internet isn’t just a technology challenge, but a management and human resource one. China offers a full-stack of options up and down the layers of the internet, including policies and laws, communications service providers with full internet shutdown options pre-installed, technical standards, satellites, cables, and infrastructure. This is possible because China has developed its own indigenous internet stack, sometimes copying the foreign technology it sought to replace. China even offers training in governance and strategy, consulting on writing a national strategy, and help building smart cities with its own full surveillance stack, euphemistically called “safe cities.”

“This is quite divorced from reality, what you are all discussing,” Simon Lewis, a climate science professor at University College London, told the oil executives during a Q+A. Lewis went on to explain to the audience that even if polluters invested in every nature conservation, sustainability agriculture or other “natural climate solution” in the world, those projects would only offset about 20% of global greenhouse gas emissions; the vast majority of cuts would still have to come about through actual reductions in fossil fuel use. Given this, Lewis asked them to explain how the initiative was any different from other corporate schemes put forth in past decades—good PR that doesn’t actually tackle the problem. In addition, carbon offset trading—which has been going on at smaller scales for decades—is no silver bullet. It has had mixed results to date, including failed projects, outright fraud, and human rights abuses against rural, indigenous and other vulnerable communities, prompting fierce opposition from grassroots climate organizations against including carbon trading in the Paris Accord. The carbon trading question is one of the remaining thorny issues country negotiators are supposed to iron out during this two-week climate conference, which ends December 13. The rules for such “market-based solutions” (included in what is technically known as Article 6 of Paris Agreement) were supposed to be decided at last year’s meeting, but countries remain far apart; in fact, some observers wonder if it won’t be punted off again until next year. Meanwhile, the oil majors have yet to unveil a plan for reducing their own company emissions in line with the Paris Agreement, which calls for dramatically reducing fossil fuel use to prevent climate catastrophe.

What China's Surveillance Means for the Rest of the World | Time
Bakitali Nur, 47, a fruit and vegetable exporter in the Xinjiang town of Khorgos, was arrested after authorities became suspicious of his frequent business trips abroad. The father of three says he spent a year in a single room with seven other inmates, all clad in blue jumpsuits, forced to sit still on plastic stools for 17 hours straight as four HikVision cameras recorded every move. “Anyone caught talking or moving was forced into stress positions for hours at a time,” he says. Bakitali was released only after he developed a chronic illness. But his surveillance hell continued over five months of virtual house arrest, which is common for former detainees. He was forbidden from traveling outside his village without permission, and a CCTV camera was installed opposite his home. Every time he approached the front door, a policeman would call to ask where he was going. He had to report to the local government office every day to undergo “political education” and write a self-criticism detailing his previous day’s activities. Unable to travel for work, former detainees like Bakitali are often obliged to toil at government factories for wages as miserly as 35¢ per day, according to former workers interviewed by TIME. “The entire system is designed to suppress us,” Bakitali says in Almaty, Kazakhstan, where he escaped in May. The result is dystopian. When every aspect of life is under constant scrutiny, it’s not just “bad” behavior that must be avoided. Muslims in Xinjiang are under constant pressure to act in a manner that the CCP would approve. While posting controversial material online is clearly reckless, not using social media at all could also be considered suspicious, so Muslims share glowing news about the country and party as a means of defense.

According to the research published today, almost every peer-reviewed climate model of human-caused global temperature rise dating back to 1970 lines up with the warming we see today. “In scientific terms, we'd say there's no bias,” the paper’s co-author Henri Drake, a PhD candidate at MIT, told me over the phone. “Once we accounted for the differences in CO2 emissions, 14 of the 17 models we analyzed were consistent with current observations.” “Taken together,” he added, “these climate models have always been quantitatively accurate.”

Low Carbon Kubernetes Scheduler
'A demand side management solution that consumes electricity in low grid carbon intensity areas':
To justify Kubernetes’ ability or globally distributed deployments the researchers chose to optimize placement to regions with the greatest degree of solar irradiance termed a Heliotropic Scheduler. This scheduler is termed ‘heliotropic’ in order to differentiate it from a ‘follow-the-sun’ application management policy that relates to meeting customer demand around the world by placing staff and resources in proximity to those locations (thereby making them available to clients at lower latency and at a suitable time of day). A ‘heliotropic’ policy, on the other hand, goes to where sunlight, and by extension solar irradiance, is abundant. They further evaluated the Heliotropic Scheduler implementation by running BOINC jobs on Kubernetes.

Climate emergency: world 'may already have crossed several tipping points’
The world may already have crossed a series of climate tipping points, according to a stark warning from scientists. This risk is “an existential threat to civilisation”, they say, meaning “we are in a state of planetary emergency”. Tipping points are reached when particular impacts of global heating become unstoppable, such as the runaway loss of ice sheets or forests. In the past, extreme heating of 5C was thought necessary to pass tipping points, but the latest evidence suggests this could happen between 1C and 2C. The planet has already heated by 1C and the temperature is certain to rise further, due to past emissions and because greenhouse gas levels are still rising. The scientists further warn that one tipping point, such as the release of methane from thawing permafrost, may fuel others, leading to a cascade.

China’s Operating Manuals for Mass Internment and Arrest by Algorithm - ICIJ
“The Chinese have bought into a model of policing where they believe that through the collection of large-scale data run through artificial intelligence and machine learning that they can, in fact, predict ahead of time where possible incidents might take place, as well as identify possible populations that have the propensity to engage in anti-state anti-regime action,” said Mulvenon, the SOS International document expert and director of intelligence integration. “And then they are preemptively going after those people using that data.” Mulvenon said IJOP is more than a “pre-crime” platform, but a “machine-learning, artificial intelligence, command and control” platform that substitutes artificial intelligence for human judgment. He described it as a “cybernetic brain” central to China’s most advanced police and military strategies. Such a system “infantilizes” those tasked with implementing it, said Mulvenon, creating the conditions for policies that could spin out of control with catastrophic results. The program collects and interprets data without regard to privacy, and flags ordinary people for investigation based on seemingly innocuous criteria, such as daily prayer, travel abroad, or frequently using the back door of their home. Perhaps even more significant than the actual data collected are the grinding psychological effects of living under such a system. With batteries of facial-recognition cameras on street corners, endless checkpoints and webs of informants, IJOP generates a sense of an omniscient, omnipresent state that can peer into the most intimate aspects of daily life. As neighbors disappear based on the workings of unknown algorithms, Xinjiang lives in a perpetual state of terror. The seeming randomness of investigations resulting from IJOP isn’t a bug but a feature, said Samantha Hoffman, an analyst at the Australian Strategic Policy Institute whose research focuses on China’s use of data collection for social control. “That’s how state terror works,” Hoffman said. “Part of the fear that this instills is that you don’t know when you’re not OK.”

Sacha Baron Cohen Uses ADL Speech to Tear Apart Mark Zuckerberg and Facebook
“if Facebook were around in the 1930s, it would have allowed Hitler to post 30-second ads on his ‘solution’ to the ‘Jewish problem,’” he said. “So here’s a good standard and practice: Facebook, start fact-checking political ads before you run them, stop micro-targeted lies immediately, and when the ads are false, give back the money and don’t publish them.” [...] “if we prioritize truth over lies, tolerance over prejudice, empathy over indifference and experts over ignoramuses” then “maybe, just maybe, we can stop the greatest propaganda machine in history, we can save democracy, we can still have a place for free speech and free expression, and, most importantly, my jokes will still work.”

A carbon-flow model for managed forest plantations was used to estimate carbon storage in UK plantations differing in Yield Class (growth rate), thinning regime and species characteristics. If the objective is to store carbon rapidly in the short term and achieve high carbon storage in the long term, Populus plantations growing on fertile land (2.7 m spacing, 26-yr rotations, Yield Class 12) were the best option examined. If the objective is to achieve high carbon storage in the medium term (50 yr) without regard to the initial rate of storage, then plantations of conifers of any species with above-average Yield Classes would suffice. In the long term (100 yr), broadleaved plantations of oak and beech store as much carbon as conifer plantations.

An interesting Amazon scam:
The end game here in many cases is for the seller to be able to pose as a verified purchaser and write a glowing review of their own product. Gaming the review system in this way pushes their products up higher in Amazon search results — regardless of whether the product is actually “good” or not. Amazon told CBS News that it investigates all customer reports of unsolicited packages like those made by the Gallivans. The company will shut down the accounts of vendors or reviewers found abusing the review system.
KIAM defaults result in massive latencies on AWS API calls
KIAM [a Kubernetes IAM API helper] happens to provide short-lived credentials to Pods, which makes sense as it’s fair to assume that the average lifetime of a Pod is shorter than EC2 instances. The default is precisely 15 min. But if you put both defaults together, you have a problem. Each certificate provided to the application has a 15 min expiration time. The AWS Java SDK will force refreshing any certificate with less than 15 min expiration time left. The result is that every request will be forced to refresh the temporary certificate, which requires two calls to the AWS API that add a huge latency penalty to each request. We later found a feature request in the AWS Java SDK that mentions this same issue. The fix was easy. We reconfigured KIAM to request credentials with a longer expiration period. Once this change was applied, requests started being served without involving the AWS Metadata service and returned to an even lower latency than in EC2.

BBC podcast's attempt to define 'shitposting' leaves viewers baffled
Laura Keunssberg, the Beeb's inept political editor, manages to make an utter mess of explaining "shitposting", claiming it's analogous to "boomer memes".

Thomas Talhelm's DIY air purifier
Simply strap a HEPA air filter to a desk fan for $30:
I tested it over and over—hundreds of days, with a control room, with a stronger fan, against the big brand purifiers that I borrowed from my rich friends. Eventually, I saw enough data that I was convinced. This $30 DIY purifier was removing significant amounts of tiny particulate from my Beijing bedroom. I wanted to tell the world that those $1,000 purifiers were ripoffs. I made all the data and testing methods open source. I wrote up the instructions for how to make one.

UK Tories pioneering 'government through shitposting'

The consultants who ran it – Topham Guerin – are now working for the Tories. So expect more dodgy memes.

How A Massive Facebook Scam Siphoned Millions Of Dollars From Unsuspecting Boomers
Since 2015, Ads Inc. has made money — lots of it — by executing one of the internet’s most persistent, lucrative, and sophisticated scams: the subscription trap. The subscription trap works by tricking people into buying what they think is a single free trial of a celebrity-endorsed product. Although the customers would receive the product — which in most cases was not made by Ads Inc. itself — in reality, the celebrity has nothing to do with the offer. And in purchasing the free trial, the customer unwittingly commits to a pricey monthly subscription designed to be hard to cancel. As for the products, a current employee described the diet and male enhancement offerings as, “the worst of the worst … China-made sawdust in a capsule.” But the subscription trap was just one part of Ads Inc.’s shady business practices. Burke’s genius was in fusing the scam with a boiler room–style operation that relied on convincing thousands of average people to rent their personal Facebook accounts to the company, which Ads Inc. then used to place ads for its deceptive free trial offers. That strategy enabled his company to run a huge volume of misleading Facebook ads, targeting consumers all around the world in a lucrative and sophisticated enterprise, a BuzzFeed News investigation has found.
