If you visit the west of Ireland or Achill, you can still see the traces of booleying today. Fascinating part of Irish rural history:
by the 1800s, it was mostly young people and teenage girls especially who had the job of looking after cows at these seasonal ‘boolies’. This gave rise to a vibrant but now largely forgotten cultural scene in Ireland’s uplands. Oral history collected in the 1930s and 1940s in Connemara, Mayo, Donegal, and the Galtee Mountains makes clear that booleying facilitated the transmission of a lot of important cultural knowledge. One man from Cloch Cheannaola in Donegal states that his mother had learned her songs from other dairymaids in the hills, while another account from Iorras Aintheach in Galway outlines how the girls not only sang but played musical instruments and danced as well. [….] The small degree of independence which young women gained as participants in booleying was sometimes missed later on in life. There is an unmistakeable sense of loss in songs like Na Gamhna Geala and Aililiú na Gamhna, in which married women reminisce about their time looking after cows and calves in the hills.

I’ve had to develop a special radar for reading product pages now: a mounting feeling of dread as a promising technology is introduced while I inevitably arrive at the buried lede: it’s more crypto bullshit. Cryptocurrency is the multi-level marketing of the tech world. “Hi! How’ve you been? Long time no see! Oh, I’ve been working on this cool distributed database file store archive thing. We’re doing an ICO next week.” Then I leave. Any technology which is not an (alleged) currency and which incorporates blockchain anyway would always work better without it. There are hundreds, perhaps thousands, of cryptocurrency scams and ponzi schemes trussed up to look like some kind of legitimate offering. Even if the project you’re working on is totally cool and solves all of these problems, there are 100 other projects pretending to be like yours which are ultimately concerned with transferring money from their users to their founders. Which one are investors more likely to invest in? Hint: it’s the one that’s more profitable. Those promises of “we’re different!” are always hollow anyway. Remember the DAO? They wanted to avoid social arbitration entirely for financial contracts, but when the chips are down and their money was walking out the door, they forked the blockchain.

The precise molecular mechanisms connecting regular activity to improved health have been unclear. A study published April 14 in Science Advances makes major gains in this understanding. Building off previous work on single bouts of exercise, researchers at Ghent University in Belgium found that when humans perform long-term training, histamine receptors are activated, improving a variety of cardiometabolic risk factors, from insulin sensitivity to aerobic capacity and blood vessel health. “It’s awesome, it’s a very cool paper,” says University of Oregon exercise physiologist John Halliwill, who was not involved in the study. “This is one of a few studies out there finally looking at these molecular transducers, and this is the only one out there on histamine that showed that it has this lasting impact on how we adapt to exercise. . . . It’s not just a signal associated with allergies and asthma, wound healing. It seems to have a hand in everything related to exercise, which is quite amazing.”

Cases of SARS-CoV-2 infection in Manaus, Brazil, resurged in late 2020, despite previously high levels of infection. Genome sequencing of viruses sampled in Manaus between November 2020 and January 2021 revealed the emergence and circulation of a novel SARS-CoV-2 variant of concern. Lineage P.1, acquired 17 mutations, including a trio in the spike protein (K417T, E484K and N501Y) associated with increased binding to the human ACE2 receptor. Molecular clock analysis shows that P.1 emergence occurred around mid-November 2020 and was preceded by a period of faster molecular evolution. Using a two-category dynamical model that integrates genomic and mortality data, we estimate that P.1 may be 1.7–2.4-fold more transmissible, and that previous (non-P.1) infection provides 54–79% of the protection against infection with P.1 that it provides against non-P.1 lineages. Enhanced global genomic surveillance of variants of concern, which may exhibit increased transmissibility and/or immune evasion, is critical to accelerate pandemic responsiveness.
Some context — European telcos no longer operate their equipment:
As an icebreaker, [telco operators] were asked if they thought the Chinese could eavesdrop through “backdoors” in Huawei equipment. Every single hand went up. One of the bankers then asked, for balance, if they thought the US could access communications through key Cisco equipment. “All the hands went straight back up without hesitation” [….] In a modern telecommunications service provider, new equipment is deployed, configured, maintained and often financed by the vendor. Just to let that sink in, Huawei (and their close partners) already run and directly operate the mobile telecommunication infrastructure for over 100 million European subscribers. The host service provider often has no detailed insight in what is going on, and would have a hard time figuring this out through their remaining staff. Rampant outsourcing has meant that most local expertise has also left the company, willingly or unwillingly.(via ITS slack)

This is the best news to happen in Ireland’s emissions situation for a while! The ESB plan to turn off the highly polluting coal power station at Moneypoint, switching it to be a hub for offshore wind energy, including energy storage using hydrogen.

What it does have is user-programmable GPIO and the rpitx package, which converts a GPIO pin into a basic radio transmitter. Of course, the Pi’s GPIO pin’s aren’t long enough to efficiently transmit at 304.2 MHz, so [River] added a proper antenna, as well as a low-pass filter to clean up the transmitted signal. The rpitx package supports OOK out of the box, so [River] was quickly able get the Pi controlling his fan in no time’
Zeynep Tufekci hits the nail on the head here — 3 particular factors were wilfully overlooked in Western countries’ early response to the COVID pandemic:
Put all three together: airborne transmission, clusters driving the epidemic, and presymptomatic transmission. Not only do we get a clear and consistent picture of many things that have happened since, we also get the mitigation strategy. Further, all three dimensions support each other: transmission from people not (yet) coughing or sneezing very much argues in favor of aerosol transmission, which explains how large clusters can be driving the epidemic and how transmission in a situation like that ship can occur. And the mitigation and other strategies become clear: pay attention to clusters and ventilation, universal masks, different policies for indoors and outdoors, etc.
Holy cow this could have been pretty serious:
A software mistake caused a Tui flight to take off heavier than expected as female passengers using the title “Miss” were classified as children, an investigation has found. The departure from Birmingham airport to Majorca with 187 passengers on board was described as a “serious incident” by the Air Accidents Investigation Branch (AAIB). An update to the airline’s reservation system while its planes were grounded due to the coronavirus pandemic led to 38 passengers on the flight being allocated a child’s “standard weight” of 35kg as opposed to the adult figure of 69kg. This caused the load sheet – produced for the captain to calculate what inputs are needed for take-off – to state that the Boeing 737 was more than 1,200kg lighter than it actually was.

Official guidance from the CDC is toning down the “bleach everything!” messaging:
People can be infected with SARS-CoV-2 through contact with surfaces. However, based on available epidemiological data and studies of environmental transmission factors, surface transmission is not the main route by which SARS-CoV-2 spreads, and the risk is considered to be low. The principal mode by which people are infected with SARS-CoV-2 is through exposure to respiratory droplets carrying infectious virus. In most situations, cleaning surfaces using soap or detergent, and not disinfecting, is enough to reduce risk. Disinfection is recommended in indoor community settings where there has been a suspected or confirmed case of COVID-19 within the last 24 hours. The risk of fomite transmission can be reduced by wearing masks consistently and correctly, practicing hand hygiene, cleaning, and taking other measures to maintain healthy facilities.Can we tone down the cleanliness theatre now?
The short version is this: we think about 1% of applications and traffic “out there” are still using TLS1.0/TLS1.1. Given where browsers are at, I think this percentage is an under-estimate of the usage on Java applications – I suspect it’s even higher there. When we dig in with customers “Why are you still using TLS1.0 or TLS1.1” the most common reasons are legacy appliances and applications. Think of hardware load balancers that were never updated, or can’t be, to support TLS1.2 or better. Compliance mandated traffic inspection devices that force TLS1.0 in certain industries are another reason. For these applications, the change will break them, and they’ll get a low-level exception. The users can re-enable TLS1.0 and TLS1.1, but they may suffer an outage because they likely weren’t expecting a breaking change low in the networking stack.

Good article on the topic of COVID-19 airborne transmission, with some decent graphics and charts
This is going to be one of the big scandals of COVID-19, when we get around to looking back from a position of safety in the future:
On 28 March 2020, two months after the WHO had declared COVID-19 a global health emergency, the agency broadcast a public-health message on Twitter and Facebook. “FACT: #COVID19 is NOT airborne,” it said, labelling claims to the contrary as misinformation. But evidence quickly established that the virus is transmitted by air, and researchers roundly criticized the agency. The WHO updated its advice on SARS-CoV-2 transmission three months later, acknowledging the possibility that airborne transmission might occur in some community settings. Airborne transmission in “crowded and inadequately ventilated spaces over a prolonged period of time with infected persons cannot be ruled out”, the updated advice says. Yuguo Li, a building environment engineer at the University of Hong Kong, says that he is disappointed it took the WHO and other health authorities so long. “We would have saved a lot of people” if airborne transmission was recognized earlier, he says.
Keith Dawson has written up a great summary of a paper by Dr. Zoë Hyde:
The general perception and belief for the last year has been that children are less likely than adults to be infected with SARS-CoV-2. A new paper in the journal Clinical Infectious Diseases casts serious doubt on this assumption. The author of that paper, Zoë Hyde of the University of Western Australia, argues that there are two principal reasons why the myth of a lower attack rate in children developed: we don’t test kids much, and they may only be infectious for a very short window of time. The CDC’s stance on kids and Covid seems to be overly sanguine. The metric used in their paper is hospitalization rate. It is true that hospitalization rates for teenagers and younger people are extremely low, but that may not be strongly indicative of infection rate. Kids’ infections are more likely to result in a mild or even asymptomatic case of Covid-19 — about twice as likely as for adults, according to Hyde. Combine this fact with the US bias towards testing only once symptoms appear, and you can see how this could contribute to an undercount of childhood cases. Compounding the dearth of testing is the (fairly robust) finding that, when infected, children may be shedding virus for a shorter time than adults: only two days on average, compared to five days for adults. So kids are more than twice as likely to show up PCR-negative even in the rare instances in which they are tested. Looking at seroprevalence surveys, Hyde cites studies from Italy and Brazil pointing to similar levels of children and adults who have antibodies indicating they have recovered from the disease. (In the Italian study from last year, children’s seroprevalence was even higher than that of the oldest adults, the result of what Hyde calls “survivorship bias” — i.e., the older people who got Covid-19 mostly died.) The hosts on This Week in Virology went over Hyde’s paper in last week’s podcast, TWiV #731. If you can spare the time, listen to 11 minutes’ worth of their discussion beginning at 23:33. One compelling point the TWiV team brought out: children are not immune from long Covid. A UK study found that 12.9% of kids had symptoms weeks after clearing the disease, compared with 22% of adults. The belief that children don’t get infected much should no longer be used as an argument for why schools ought to be reopened.

Well done, Slovakia — massive decrease in prevalence after 2 rounds of mass testing.
Slovakia conducted multiple rounds of population-wide rapid antigen testing for SARS-CoV-2 in late 2020, combined with a period of additional contact restrictions. Observed prevalence decreased by 58% (95% CI: 57-58%) within one week in the 45 counties that were subject to two rounds of mass testing, an estimate that remained robust when adjusting for multiple potential confounders. Adjusting for epidemic growth of 4.4% (1.1-6.9%) per day preceding the mass testing campaign, the estimated decrease in prevalence compared to a scenario of unmitigated growth was 70% (67-73%). Modelling indicated that this decrease could not be explained solely by infection control measures, but required the additional impact of isolation and quarantine of household members of those testing positive.

Amazing well-preserved human footprints from between 4200 and 4600 years ago:
The Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) has participated in chapter 17, which covers the prints of bare feet preserved in the soft floor sediment of Palomera Cave in the Ojo Guareña Karst Complex (Merindad de Sotoscueva, Burgos, Spain). These footprints, ascribed to traces left by about ten individuals who explored the caves between 4200 and 4600 years ago, were discovered in 1969 by Grupo Espeleológico Edelweiss (GEE) at the Sala y Galerías de las Huellas site, some 1200 m from the entrance to Palomera Cave. The fragility of the footprints and their environment meant it was not possible to study them, and doing so has had to await the development of the new non-invasive teledetection techniques.

This is great. An amulet is ‘a kind of poem that depends on language, code, and luck. To qualify, a poem must satisfy these criteria: Its complete Unicode text is 64 bytes or less; and the hexadecimal SHA-256 hash of the text includes four or more 8s in a row.’
The hash is a cold hexadecimal spew – 9a120001cc88888363fc67c45f2c52447ae64808d497ec9d699dba0d74d72aab – and, like a fingerprint, it doesn’t tell you anything about the entity it identifies. That’s by design, but even so, it feels strange for a value so pivotal to be totally disconnected from the underlying content, especially when it is this value that’s being collected and traded in cryptographic marketplaces. Ostensibly, the hash provides an immutable link between unique cryptographic object and free-floating digital media. The amulet asks: what if we took that link seriously? In a sense, the definition of the SHA-256 hash function created, at a stroke, all amulets of all rarities. Common to mythic, trashy to lovely, they have been hiding in the manifold combinations of language; we just didn’t know we ought to be looking for them. Until now!
This is comedy gold. Turns out some digital phrenology software used for AI-aided interviewing will produce higher results for candidates who simply have a bookshelf as a background. As Daniel Bilar puts it: it’s the “Clever Hans” phenomenon, […] ‘spurious correlations, can occur when there is a feature in the data that is highly correlated with the correct outcome, but is not the cause for the answer being correct.’
Via Colman Reilly — this really sounds like outright fraudulent behaviour by FB:
The filing also reveals that a Facebook product manager for the “potential reach” tool warned the company was making revenue it “should never have” off of “wrong data”. The unsealed documents pertain to a U.S. class action lawsuit, filed in 2018, which alleges that Facebook deceived advertisers by knowingly including fake and duplicate accounts in a “potential reach” metric. Facebook denies the claim but has acknowledged accuracy issues with the “potential reach” metric as far back as 2016 — and also changed how it worked in 2019. […] Redacted documents from the lawsuit, reported by the WSJ last year, included the awkward detail that a Facebook employee had asked “how long can we get away with the reach overestimation?”
This is pretty solid real-world data, IMO — even if they’re not testing correctly to find it, it’s there in the ONS data
Testing people with any of the three ‘classic’ symptoms would have spotted 69% of symptomatic cases, with 46 people testing negative for every person testing positive. However, testing people with any of seven key symptoms – cough, fever, anosmia, fatigue, headache, sore throat and diarrhoea – in the first three days of illness would have detected 96% of symptomatic cases. In this case, for every person with the disease identified, 95 would test negative. Researchers also found users of the Symptom Study App were more likely to select headache and diarrhoea within the first three days of symptoms, and fever during the first seven days, which reflects different timings of symptoms in the disease course. Data from the ZOE app shows that 31% of people who are ill with COVID-19 don’t have any of the triad of symptoms in the early stages of the disease when most infectious.

1. Effective lockdown leading to low transmission rates can essentially eliminate common #SARS_CoV_2 variants contributing to disease ..BUT.. 2. ..new variants can be introduced (likely [via] travel) that seed new waves of #COVID19. As daily infections fall, hopefully correct implementation of new travel restrictions can help stop future W4 of #COVID19Ireland. We also hope that this data helps people understand how travel contributes to new #COVID19 infections (and new variants) coming into the country.
via John McClean: Imperial College COVID-19 Response Team report on premature reopening under different vaccination strategies in the UK. They find significant risk of a large 3rd wave of infections: ‘For all gradual easing of NPI scenarios explored, unless vaccination is rapidly ramped up to 3 million doses a week, gradual lifting of NPIs from 1st March to 1st July will lead to a third wave of hospitalisations which will exceed our indicative threshold of 25,000 beds national hospital capacity.’
Excellent article from Tomas Pueyo on the new COVID-19 variants:
In the race between the variants and the vaccines, the variants are the hare and the vaccines are the tortoise. We all know that, in the end, the vaccines will win. Like the tortoise. By this summer, in developed countries, vaccination rates will likely range between 50% and 80%. Since there will also be some herd immunity, and summer means outdoors in the Northern hemisphere, it’s likely that the pandemic will die down some time during the summer. The question is: Will they also be rolled out in time to prevent the new variants from taking over? Now we have our answer: Unfortunately, no.TBH, though, I am not so sanguine about the results for the Northern hemisphere. With open borders, no mandatory quarantine, and the rest of the world suffering without sufficient access to vaccines, new variants will keep passaging and keep emerging, risking putting our vaccine progress back to square one. (via Cormac)

Galvão, the lead physician in the coronavirus ward at a public hospital in the Brazilian city of Manaus, had been haunted by the wave that crashed last spring. In less than 10 days, it ruptured the city’s bewildered medical system. Sick patients were turned away. The dead were piled into mass graves. So Galvão’s hospital organized contingency plans. Additional beds were reserved, and a detailed schedule for opening them was created. But the new surge, when it came, was different. The virus had mutated, with a suite of alterations that probably made it more transmissible — and perhaps more lethal. Manaus was hit by what scientists call the P.1 variant. This time, it didn’t take 10 days to overwhelm Galvão’s hospital. It took 24 hours.

Recent preprint paper from the UK —
Adjusting for patient-level factors, mortality was higher for admissions during periods of high occupancy (>85% occupancy versus the baseline of 45 to 85%) [OR 1.19 (95% posterior credible interval (PCI): 1.00 to 1.44)]. In contrast, mortality was decreased for admissions during periods of low occupancy (<45% relative to the baseline) [OR 0.75 (95% PCI: 0.62 to 0.89)]. [...] The results of this study suggest that survival rates for patients with COVID-19 in intensive care settings appears to deteriorate as the occupancy of (surge capacity) beds compatible with mechanical ventilation (a proxy for operational pressure), increases. Moreover, this risk doesn’t occur above a specific threshold, but rather appears linear; whereby going from 0% occupancy to 100% occupancy increases risk of mortality by 92% [...]As Andrew Kunzmann noted – “To aid interpretation, the difference in risk for a 70-year-old man with no comorbidities being admitted during a period of high versus low occupancy is equivalent to the risk if they were approximately a decade older”.
A recent preprint from China — lots of “long COVID” impact, still:
