This Week I Learned -
* Migrate for Anthos is one of the most scalable approaches to modernize applications with Kubernetes orchestration, image-based container management and DevOps automation. Migrate for Anthos automatically generates a container image, a Dockerfile for day-2 image updates and application revisions, Kubernetes deployment YAMLs and (where relevant) a persistent data volume onto which the application data files and persistent state are copied. This automated, intelligent extraction is significantly faster and easier than manually modernizing the app, especially when source code or deep application rebuild knowledge is unavailable. Unlike VMs, all containers on a single node share one copy of the operating system and don’t each require their own OS image and vCPU, resulting in a much smaller memory footprint and CPU needs. This means more workloads running on fewer compute resources.
* The Five Disciplines of Cloud Governance in the Cloud Adoption Framework
* Private clouds are commonly used for predictable workloads (75% according to IDC) and the elastic nature and consumption-based charge of public clouds are good at supporting unpredictable workloads. Without proper visibility, businesses won't even know what's driving their public cloud costs. Start with a secure private cloud and slowly move applications to a public cloud as growth demands. Slowly move resources and expand to a hybrid cloud model. Private cloud is known as the most secure option but it needs to be built that way - Nutanix: Top 20 Private Cloud Questions
* Wikipedia turned 20 years old on Friday, 15 January 2021
* Social-media service Parler vanished on 10th January, when Amazon.com Inc. followed through on its threat to stop hosting the public-messaging platform that has exploded in popularity among supporters of President Trump. Parler’s effective disappearance came shortly after Apple Inc. and Alphabet Inc.’s Google removed the Parler app for mobile devices from their app stores - WSJ
* Signal is developed by the Signal Foundation, a non-profit funded by a loan from Brian Acton (co-creator of WhatsApp) of $105m, repayable in 2068 at 0% interest. He co-founded WhatsApp with Jan Koum in 2009 and it was acquired by Facebook in February 2014 for US$19 billion.
* The United States celebrates the birthday of Martin Luther King Jr on the 3rd Monday of January every year, giving people a 3 day weekend.
* Mufti Mohammed Sayeed, was sworn in as India’s first Muslim home minister in the VP Singh government. His daughter Rubaiya was kidnapped a few days later and released after the Farooq Abdullah government released five militants as demanded by the JKLF. Mufti later formed the J&K People’s Democratic Party in 1999 and became chief minister in 2002 and 2015. Rubaiya never joined politics but her sister Mehbooba took over the mantle from Mufti after his demise.
* Food Corporation of India distributes 47.5 million tonnes of food grains every year to 800 million poor people at subsidised rates under national food security act (NFSA).
* National Defence Academy, Khadakwasla was inaugurated on 16 Jan 1955. The three chiefs of the Indian Armed Forces are NDA Coursemates(1976).
* Bahrain has fewer than 2m residents, the UAE fewer than 10m. Bahrain and the UAE authorised Sinopharm's BBIBP-CorV vaccine in December after declaring it 86% effective. BBIBP-CorV is based on an inactivated strain of the SARS-CoV-2 virus, a long-established way of making vaccines, rather than the new mRNA technology used by Pfizer and other Western manufacturers. Many countries have been reluctant to approve BBIBP-CorV because it lacks reliable trial data. There are few reservations in the Gulf about BBIBP-CorV partly due to public trust in governments with a reputation for being well-run. The UAE’s embrace of Sinopharm is bringing them closer to China. State-run telecoms firms in the Emirates have awarded 5G contracts to Huawei, which is blacklisted by America. Military ties are growing as well, with the UAE fielding Chinese-made attack drones in Libya - The Economist
* Japan has the world’s longest life expectancy, and 80,000 centenarians. Japan has long had one of the lowest sugar-consumption rates among the OECD countries, a club of mainly wealthy countries. Japan largely banned meat for 1,200 years, and still consumes relatively little meat and dairy. The unhappy irony is that Japan’s health gains, paired with a low birth rate, threaten its economy. By 2060, 40% of Japanese could be 60 or older. In a study of 48,000 Britons, vegetarians were unusually resistant to heart disease, but prone to strokes. Japan’s rate of strokes fell during a period when it began eating a bit of meat. - The Economist
* FAST test for stroke that you can go through to determine if emergency medical care is needed:
- Face: Ask person to smile and notice if one side starts to droop compared to the other.
- Arm: Have the person raise both his arms. Notice if one side is lopsided compared to the other.
- Speech: Give the person a phrase to repeat back to you. Does the person have difficulty with speaking it or does it sound strange?
- Time: If any of these symptoms are observed, emergency care might be necessary.
* Ear training or aural skills is a music theory study in which musicians learn to identify pitches, intervals, melody, chords, rhythms, solfeges, and other basic elements of music, solely by hearing. The application of this skill is analogous to taking dictation in written/spoken language.
* "Patterns are funny things, for you can see them your entire life without ever noticing them. But once you finally notice, they appear everywhere. When I learned to notice this pattern, it was like finally seeing the world in three dimensions—I was still looking at the same objects, but now everything had depth. My enhanced vision revealed even more patterns. Patterns that have changed the world." - Jim Mckelvey, Innovation Stacks
