“CryptoHack is a fun platform for learning cryptography. The emphasis is on breaking bad implementations of “modern” crypto, such as AES, RSA, and Elliptic-curve. The format is a series of puzzles that teach small lessons and motivate further research.”
“Ellen Biros, MS, LCSW, a therapist in Suwanee, Georgia, describes grey rocking as a technique for interacting with manipulative and abusive people. This can include people with narcissistic personality disorder or antisocial personality disorder as well as toxic people without a mental health diagnosis…She goes on to explain that since people with manipulative personalities feed on drama, the duller and more boring you seem, the more you undermine their efforts to manipulate and control you.”
“This new coronavirus—dubbed SARS-CoV-2—is unquestionably dangerous. It causes a disease called COVID-19, which can be deadly, particularly for older people and those with underlying health conditions. While the death rate among infected people is unclear, even some current low estimates are seven-fold higher than the estimate for seasonal influenza.
And SARS-CoV-2 is here in the US, and it’s circulating—we are only starting to determine where it is and how far it has spread. Problems with federal testing have delayed our ability to detect infections in travelers. And as we work to catch up, the virus has kept moving. It now appears to be spreading in several communities across the country. It’s unclear if we will be able to get ahead of it and contain it; even if we can, it will take a lot of resources and effort to do it.”
Beth Mole’s science writing is on point. But, let’s not lie to ourselves. This idea that the United States is going to contain this pandemic is nothing short of fantasy. By May, there will be hospital crises across the country, and it will likely resurge in October after a summer lull. Best to accept this as fact.
“Spaced repetition is a centuries-old psychological technique for efficient memorization & practice of skills where instead of attempting to memorize by ‘cramming’, memorization can be done far more efficiently by instead spacing out each review, with increasing durations as one learns the item, with the scheduling done by software. Because of the greater efficiency of its slow but steady approach, spaced repetition can scale to memorizing hundreds of thousands of items (while crammed items are almost immediately forgotten) and is especially useful for foreign languages & medical studies.
I review what this technique is useful for, some of the large research literature on it and the testing effect (up to ~2013, primarily), the available software tools and use patterns, and miscellaneous ideas & observations on it.”
“The field of genomic epidemiology focuses on using the genetic sequences of pathogens to understand patterns of transmission and spread. Viruses mutate very quickly and accumulate changes during the process of transmission from one infected individual to another. The novel coronavirus which is responsible for the emerging COVID-19 pandemic mutates at an average of about two mutations per month. After someone is exposed they will generally incubate the virus for ~5 days before symptoms develop and transmission occurs…
…We believe this may have occurred by the WA1 case having exposed someone else to the virus in the period between Jan 15 and Jan 19 before they were isolated. If this second case was mild or asymptomatic, contact tracing efforts by public health would have had difficulty detecting it. After this point, community spread occurred and was undetected due to the CDC narrow case definition that required direct travel to China or direct contact with a known case to even be considered for testing. This lack of testing was a critical error and allowed an outbreak in Snohomish County and surroundings to grow to a sizable problem before it was even detected.
…We know that Wuhan went from an index case in ~Nov-Dec 2019 to several thousand cases by mid-Jan 2020, thus going from initial seeding event to widespread local transmission in the span of ~9-10 weeks. We now believe that the Seattle area seeding event was ~Jan 15 and we’re now ~7 weeks later. I expect Seattle now to look like Wuhan around ~1 Jan, when they were reporting the first clusters of patients with unexplained viral pneumonia. We are currently estimating ~600 infections in Seattle, this matches my phylodynamic estimate of the number of infections in Wuhan on Jan 1.”
Roughly speaking, the take-away from this article is that 9-10 weeks after you have cases in your area, you should expect widespread transmission. The article outlines things you can do to minimize your risk of exposure:
Practicing social distancing, such as limiting attendance at events with large groups of people
Working from home, if your job and employer allows it
Staying home if you are feeling ill
Take your temperature daily, if you develop a fever, self-isolate and call your doctor
Implementing good hand washing practices – it is extremely important to wash hands regularly
Covering coughs and sneezes in your elbow or tissue
Avoiding touching your eyes, nose, and mouth with unwashed hands
Disinfecting frequently touched surfaces, such as doorknobs
Beginning some preparations in anticipation of social distancing or supply chain shortages, such as ensuring you have sufficient supplies of prescription medicines and ensuring you have about a 2 week supply of food and other necessary household goods.
With these preparation in mind, it is important to not panic buy. Panic buying unnecessarily increases strain on supply chains and can make it difficult to ensure that everyone is able to get supplies that they need.
“The basic value in Kant’s ethics is that of human dignity – the rational nature in persons as end in itself. A person is a being for whose sake we should act, and that has an unconditional claim on us. This is the source of what Kant calls a categorical imperative: a ground for action that does not depend on any contingent desire of ours or any end to be effected by action set at our discretion. John Rawls corrected the basic and traditional misunderstanding of Kant’s ethics when he said that it is not an ethics of stern command but rather one of self-esteem and mutual respect. To this I would add that Kant’s ethics is also an ethics of caring or empathy – what Kant calls Teilnehmung: sympathetic participation. This is not sympathy merely in the sense of passive feeling for or with others, but instead an active taking part in the standpoint of the other which leads to understanding and concern.”
“The document, a product of our joint investigation with ZDF Frontal21, gives exclusive insight into the million euro business of climate change deniers. It proves how disinformation is professionally scattered around society with the help of supposed experts, corrupt scientists, intentional spin and YouTube.”
“Most people will have a positive emotion to the first sentence, a mild reaction to the second, and a negative reaction to the third. Likewise, writers can vary the meaning of their words by changing the length or structure of their sentences. Once their words are set in print, they can enhance their messaging with images that manipulate the reader’s emotions.”
“Many if not most people form their opinions based solely on whatever [Emotive] Conjugation is presented to them and not on the underlying facts.
Most words and phrases are actually defined not by a single dictionary description, but rather two distinct attributes:
Open Questions: Will agriculture by fundamentally transformed in the next decade? And if so, what are the likely health implications?
We are on the cusp of the biggest economic transformation, of any kind, for 200 years. While arguments rage about plant- versus meat-based diets, new technologies will soon make them irrelevant. Before long, most of our food will come neither from animals nor plants, but from unicellular life. After 12,000 years of feeding humankind, all farming except fruit and veg production is likely to be replaced by ferming: brewing microbes through precision fermentation. This means multiplying particular micro-organisms, to produce particular products, in factories.”
“We are on the cusp of the deepest, fastest, most consequential disruption in food and agricultural production since the first domestication of plants and animals ten thousand years ago. This is primarily a protein disruption driven by economics. The cost of proteins will be five times cheaper by 2030 and 10 times cheaper by 2035 than existing animal proteins, before ultimately approaching the cost of sugar. They will also be superior in every key attribute – more nutritious, healthier, better tasting, and more convenient, with almost unimaginable variety. This means that, by 2030, modern food products will be higher quality and cost less than half as much to produce as the animal-derived products they replace.”
