* The Computer Vision API response holds the insight the REST API has about your image, as a JSON payload. The Azure CLI 2.0 uses the --query argument to execute a JMESPath (JSON Matching Expression paths) query on the results of commands. JMESPath is a query language for JSON, giving you the ability to select and present data from CLI output. These queries are executed on the JSON output before any display formatting. The --query argument is supported by all commands in the Azure CLI.

* AWS CLI & Azure CLI 2.0 support JMESPath

* Tsundoku is a Japanese word for a stack of books that you have purchased but not yet read.

* China has been collecting DNA samples from its men and school-age boys, with the aim to generate genetic profiles of nearly 70 million from the country’s overall male population. The genetic data gleaned from this pool, Nature reports, can be used to construct genetic links to China’s entire male population, since the marker at the heart of this exercise are Y-chromosome’s short tandem repeats (STRs)—that is certain combinations of bases pairs (upto 6) getting repeated anywhere between 5-50 times on a chromosome. Y-STRs, which are used in forensics and genealogical testing, are extremely similar among males of common paternal lineage. While most countries do use DNA profiling for forensics, the scale at which China’s ministry of public security is doing this—expanded from its earlier DNA profiling for forensics—is unprecedented - Financial Express

* The pandemic has spared the Buddhist parts of South-East Asia. Vietnam’s communist dictatorship is atheist. At the start of the year it instinctively distrusted China’s reassurances about covid-19 and even launched cyber-attacks to get better information on the epidemic’s course. It closed its border and used authoritarian powers to lock down the population and trace and isolate cases. The quality of its health care makes Thailand (a sham democracy overseen by generals,) a popular destination for medical tourism. The government was quick to set up a vigorous covid-fighting task-force. Even the poorest countries adopted measures that must have helped check the spread of the coronavirus. Other factors that may have helped..a pre-existing proclivity for masks..the wai, a Buddhist greeting of palms pressed together, helps with social distancing - The Economist

* In December 1961, India forcibly expelled the Portuguese from Goa. The "armed action" was code named Operation Vijay (meaning "Victory") by the Indian Armed Forces. It involved air, sea and land strikes for over 36 hours, and was a decisive victory for India, ending 451 years of rule by Portugal over its remaining exclaves in India. The engagement lasted two days, and twenty-two Indians and thirty Portuguese were killed in the fighting.
