This Week I Learned - Week #40 2020
This Week I Learned -
* Azure Advisor reports new features and security issues related to AKS
* Pods within a K8s node can have startup and runtime errors
* The Kubernetes community releases minor versions roughly every three months. Recently the Kubernetes community has increased the window of support for each version from 9 months to 12 months, starting with version 1.19. Kubernetes follows this numbering scheme: [major].[minor].[patch]. The supported window of Kubernetes versions on AKS is known as "N-2": (N (Latest release) - 2 (minor versions)). Older versions will be removed and will be out of support in 30 days. Clusters running unsupported Kubernetes releases are not covered by the AKS support policies. If a cluster has been out of support for more than three (3) minor versions and has been found to carry security risks, Azure contacts you to proactively upgrade your cluster. If you do not take further action, Azure reserves the right to automatically upgrade your cluster on your behalf.
* Windows 8 was followed by Windows 10, which is actually the 11th consumer version of Windows. The second Xbox was the Xbox 360, and the third Xbox was called the Xbox One.
* Elements of AI is a living course that will keep getting updated
* Performing his autopsy on Auguste Deter in 1906, Alois Alzheimer noticed three unusual features of her brain. It was at least a third smaller than normal. Many neurons, the nerve cells, had vanished. He also saw abnormal deposits inside the remaining cells, especially in the cerebral cortex, the thin outer layer of grey matter. Between a third and a quarter had been invaded by dense knotty bundles, now known as “neurofibrillary tangles”, caused by a build-up of a protein called tau. And across the cortex were deposits of another protein, since identified as beta-amyloid, which collect between neurons and disrupt their functioning. Three genes have been implicated in the rare, inherited, early-onset form of Alzheimer’s. For the more common sort, several genes have been found to increase the risk, particularly one form of the apoe gene, apoe4, which also appears to raise the risk of heart disease and covid-19.
* A study presented at the July Alzheimer’s Association conference estimated that dementia could be prevented or delayed in 40% of cases by attacking 12 risk factors. It added three (excessive drinking or incurring head injuries in middle life, and exposure to air pollution in old age) to nine already identified (including smoking, high blood pressure, obesity, hearing loss, less education and diabetes)....impaired spatial awareness and sense of direction are often early signs of dementia
* “data tech is progressing much faster than biotech”. Data research should allow more extensive mapping of correlations between physical conditions and behaviour and the later onset of dementia. - The Economist
* Helping the business to navigate through covid-19 will undoubtedly continue to elevate the strategic importance of CTOs within their organizations. Indeed, there are a growing number of examples of CTOs who have gone on to become CEO. Many of them are in technology companies, such as the current heads of US and UK telecommunications carriers Verizon and BT Openreach, but there are also examples from organizations that would not traditionally be considered “tech companies,” including GE Transportation, the UK’s National Health Service, and Indonesia’s Garuda airline. - MIT Technology Review
* On an average, it takes 7 years to be an unicorn in India
* Indian visual effects (VFX) company Prime Focus earned $4 million (over Rs 18 crore) from a deal to create 200 shots of the 1,600-odd shots in Avatar. The film's title refers to a genetically engineered Na'vi body operated from the brain of a remotely located human that is used to interact with the natives of Pandora.
* Arabic, Hebrew, Pashto, Persian, Urdu, and Sindhi are the most widespread RTL writing systems in modern times.
* pax means people/persons/occupants
* Shivraj Singh Chouhan served as the Chief Minister of the Madhya Pradesh, between 2005 and 2018 and five-time Member of Parliament, having represented Vidisha in the Lok Sabha, the lower House of the Indian Parliament, between 1991 and 2006.
* Eli Cohen, was an Israeli spy best known for his espionage work in 1961–65 in Syria, where he developed close relationships with the Syrian political and military hierarchy, and became the chief adviser to the Minister of Defense.
* Robert Bilott is an American environmental attorney who has spent more than twenty years litigating hazardous dumping of the chemicals perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) by DuPont. Bilott's story also became the basis for Dark Waters, a 2019 film starring Mark Ruffalo as Bilott.
* Taiwan has all but returned to normal. The national death toll due to Wuhan Corona? Seven. It was enabled through the use of open data and transparent governance
* Vaccines help develop immunity by imitating an infection. This type of infection, however, almost never causes illness, but it does cause the immune system to produce T-lymphocytes and antibodies. Sometimes, after getting a vaccine, the imitation infection can cause minor symptoms, such as fever.
