This Week I Learned -
* AWS Patch Manager automates the process of patching Windows and Linux managed instances. Use this feature of AWS Systems Manager to scan your instances for missing patches or scan and install missing patches. You can install patches individually or to large groups of instances by using Amazon EC2 tags.
* Dell EMC Storage options include all-flash, cloud and software-defined systems for entry, midrange and enterprise businesses.
* A lot of successful start-ups launched with a different business model, and when they ran into trouble, they pivoted to something new. Like Instagram. That was a location-based check-in service when it started. - Silicon Valley, S1E8
* The first official zebra crossing stripes were officially first used in Slough, just west of London, on October 31, 1951. By the end of the year, the British government had adopted it widely for pedestrian crossings.
* Foreign-born immigration has caused the U.S. population to continue its rapid increase, with the foreign-born population doubling from almost 20 million in 1990 to over 45 million in 2015. White people constitute the majority of the U.S. population, with a total of about 234,370,202 or 73% of the population as of 2017. Including multiracial people, the white share of the population exceeds 75%.
* New York City is the most populous city in the United States and has been since at least 1790.
* Rainforests are responsible for roughly one-third (28%) of the Earth's oxygen but most (70%) of the oxygen in the atmosphere is produced by marine plants. The remaining 2 percent of Earth's oxygen comes from other sources. The ocean produces oxygen through the plants (phytoplankton, kelp, and algal plankton) that live in it. These plants produce oxygen as a byproduct of photosynthesis, a process which converts carbon dioxide and sunlight into sugars the organism can use for energy. One type of phytoplankton, Prochlorococcus, releases countless tons of oxygen into the atmosphere. It is so small that millions can fit in a drop of water. Prochlorococcus has achieved fame as perhaps the most abundant photosynthetic organism on the planet. The health of all organisms in the ocean is connected to the health of phytoplankton. - Nat Geo
* Prenuptial agreements are not valid in India. Any contract which has marriage as an object is null and void
* Sitting around Fateh Singh Rathore’s campfire under the banyan tree outside Jogi Mahal, Ranthambhore, Bittu Sahgal made a rash promise to his mentor in 1980 that on his return to Mumbai he would start a wildlife magazine and galvanise urban Indians in support of the country’s wilds. The first issue of Sanctuary Asia rolled out in October 1981, with no business plan, no editorial experience and no capital. The magazine survived. Over thirty-five years it snowballed into a larger conservation movement of action, communication and advocacy, leading to the establishment of the Sanctuary Nature Foundation in 2015.
* In the 1984 Parliamentary elections, Mamata Banerjee defeated the CPM stalwart Somnath Chatterjee in her first political battle to win the Jadavpur constituency. In 1998, she broke away and launched the Trinamool Congress. All through her life she has proved to be a path-breaking politician who has reacted more on impulse than on political doctrine and diplomatic calculations. She single-handedly wrecked the red bastion in West Bengal, ending the Left Front's uninterrupted 34-year-old rule to become the Chief Minister in 2011.
* Dr. Krishna Ella founded Bharat Biotech in 1996 at Genome Valley, Hyderabad, together with his wife Suchitra Ella. With more than 140 patents, Bharat Biotech has over 16 vaccines for bio-therapeutics, registered in 116 countries and the WHO prequalified vaccines in its portfolio. Bharat Biotech has successfully developed Rotavac, the most affordable vaccine against rotavirus induced diarrheal infections and death in the world.
* Raga is the musical framework within which singers have the freedom to improvise.
* Hindustani, or northern Indian, classical music, an art form that calls forth a near-religious devotion from its adherents...it demands technical skill, improvisatory brilliance and .. a daunting, possibly unattainable degree of spiritual and philosophical purity. - LA Times
* Although Africa’s 1.3bn people offer a huge market for medicines, it imports 99% of the vaccines it uses (and 70% of its pharmaceutical products). - Economist
* Solipsism is the philosophical theory that what's in your mind is the only reality that can be known and verified.
* "If the last year has taught us anything, it is that people are tired of the Warren Buffetts and Charlie Mungers of the world acting like they are the only oracles of investing....Progress is adapting our old ways, and has always been how we advance as a society. From the automobile, to radio, to the internet, to the smartphone — technology is the great equalizer. And when it comes to investing, equal opportunity and accessibility is exactly what Robinhood is built to provide." - Robinhood
