Specifications for simple open source mechanical ventilator
from Julian Botta, Johns Hopkins Emergency Medicine Resident PGY-3 , Twitter: @julianbotta ‘This is a living document intended to give non-clinicians/non-respiratory therapists an idea of key ventilator features and one proposed simplified design. I encourage other healthcare professionals who are very familiar with ventilators and their use to give me feedback using the comments feature to improve these specifications.’

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.

Global MediXchange for Combating COVID-19 – Alibaba Cloud
The Jack Ma Foundation and Alibaba Foundation, together with the First Affiliated Hospital of Zhejiang University, jointly established the Global MediXchange for Combating COVID-19 (GMCC) programme, with the support of Alibaba Cloud Intelligence and Alibaba Health, to help combat the global outbreak of the novel coronavirus, COVID-19. This platform was established to facilitate continued communication and collaboration across borders, as well as to provide the necessary computing capabilities and data intelligence to empower pivotal research efforts. The platform can provide frontline medical teams with the necessary communication channels to share practical experience and information about fighting the pandemic.

Another privacy-preserving COVID-19 contact-tracing app, this one from MIT:
The news: An app that tracks where you have been and who you have crossed paths with—and then shares this personal data with other users in a privacy-preserving way—could help curb the spread of Covid-19, says Ramesh Raskar at the MIT Media Lab, who leads the team behind it. Called Private Kit: Safe Paths, the free and open-source app was developed by people at MIT and Harvard, as well as software engineers at companies such as Facebook and Uber, who worked on it in their free time.

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.
This also introduced me to a new concept, “herd protection”, which is described as “Ronald Ross’s great discovery: you don’t need to stop all infections to stop an epidemic, you need to get and keep R<1."(tags: papers toread covid-19 social-distancing movement cordons quarantine epidemics pandemics china smartphones location herd-protection)

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.

Chris Hayes on Twitter: “A doctor I spoke to today called this the “paradox of preparation” and it’s the key dynamic in all this. The only way to get ahead of the curve is to take actions that *at the time* seem like overreactions, eg: Japan closing all schools for a month with very few confirmed cases”. See also the Millennium Bug, and what’s currently (failing) to happen with climate change. This is a great concept, and good to have a name for it.

If You Go Out Now, You Might Feel Guilty Later. I Do.
Others have written eloquently of the importance of social distancing. But the scale and scope of this is something every single one of us is having to grapple with. Things that felt like a dumb overreaction a week ago — “Canceling vacation? Really?” — now feel hilariously quaint. Or if they don’t, they will soon. If you still can’t quite believe that you need to take these measures, or that people’s lives may hang in the balance, or if you still think that it will be okay because the numbers where you live aren’t so bad yet, I am not here to scold you. But if you do go out, and you do risk infecting somebody else, you may feel the guilt — and the fear — that I’m struggling with right now. Trust me, it’s not worth it.

There were no strategies for protecting the vulnerable and there had been a failure to engage the public. “We have a superficial prime minister who has got no grasp of public health,” Ashton said. “Our lot are behaving like 19th-century colonialists playing a five-day game of cricket. “This virus will find the weak points. You can’t just plan this from an office in Whitehall. It’s pathetic. The government doesn’t seem to understand classic public health. You need to be out and about.

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.

Trees on commercial UK plantations ‘not helping climate crisis’

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)

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.

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.

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.”
