* RBAC is an authorization system built on Azure Resource Manager that provides fine-grained access management of resources in Azure.
* Hub and spoke is a networking model for more efficient management of common communication or security requirements. It helps avoid Azure subscription limitations, save costs by centralizing services that can be shared by multiple workloads and aids separation of concerns through deployment of individual workloads between central IT teams and workload teams.
* The hub is a virtual network (VNet) in Azure that acts as a central point of connectivity to your on-premises network. The spokes are VNets that peer with the hub, and can be used to isolate workloads.
* A hub-spoke topology can also be used without a gateway, if you don't need connectivity with your on-premises network.
* As a first step toward migrating a datacenter to the cloud, the first services that need to be shared are identity and security services such as DNS, IDS, NTP, or AD DS. Shared services are placed in the hub VNet, while each environment is deployed to a spoke to maintain isolation.
* VNet peering is non-transitive. In order to implement spoke to spoke communication, exclusively allow peering between spokes or deploy Azure Firewall or an NVA for routing in the hub, and use UDRs in the spoke to forward traffic to the hub.
* Azure Data Factory Data (ADF) leverages a Self-Hosted Integration Runtime (SHIR) service to connect on-premises and Azure data sources. SHIR can run copy activities between a cloud data store and a data store in a private network, and it can dispatch transform activities against compute resources in an on-premises network or an Azure virtual network.
* Microbrowsers are simple-brained browsers, a class of User-Agents that also visit website links, parse HTML and generate a user experience. But unlike those traditional browsers, the HTML parsing is limited and the rendering engine is singularly focused. It is the little thumbnail preview of a website mentioned in a tweet, the expanded description in a Slack channel, or in WhatsApp group chat. The experience is not intended to be interactive. Rather the experience is intended to be representational - to give the user a hint of what exists on the other side of the URL. Page requests from Microbrowsers don’t run JavaScript and they don’t accept cookies. Some of these Microbrowsers impersonate real browsers and others impersonate Facebook or Twitter.

* Design System Checklist
* A very small percentage of people may experience a seizure when exposed to certain visual images, including flashing lights or patterns that may appear in video games. Even people who have no history of seizures or epilepsy may have an undiagnosed condition that can cause these “photosensitive epileptic seizures” while playing video games. You may reduce risk of photosensitive epileptic seizures by taking the following precautions:
- Play in a well-lit room.
- Do not play if you are drowsy or fatigued.
* According to a study, even though 76% of working professionals believe that a mentor is important to growth, more than 54% do not have such a relationship.
* Tharangambadi, formerly Tranquebar, is a town in the Nagapattinam district of the Indian state of Tamil Nadu on the Coromandel Coast. Tranquebar was established in 1620 as the first Danish trading post in India. King Christian IV had sent his envoy Ove Gjedde who established contact with Raghunatha Nayak of Tanjore. An annual tribute was paid by the Danes to the Rajah of Tanjore until the colony of Tranquebar was sold to the British East India Company in 1845.
* Denmark is about the same size as Haryana. The top five popular last names in Denmark are Nielsen, Jensen, Hansen, Pedersen, Andersen and most others end with "sen" which means "son of".
* There are officially 6852 islands in Japan and has a coastline bigger than Australia
* Indigo remained a rare commodity in Europe throughout the Middle Ages. In the mid-1660s, when Newton bought a pair of prisms at a fair near Cambridge, the East India Company had begun importing indigo dye into England. Isaac Newton introduced indigo as one of the seven base colors of his work. Being a cash crop which needed high amounts of water and which left the soil infertile, local farmers usually opposed its cultivation, instead preferring to grow daily need crops such as rice and pulses. The British colonialists forced farmers to grow indigo, often by making this the condition for providing loans, and through collusion with local kings, nawabs and landlords. When Gandhiji returned to India from South Africa in 1915, and saw peasants in Northern India oppressed by indigo planters, he tried to use the same methods that he had used in South Africa to organize mass uprisings by people to protest against injustice. The farmer's uprising that took place in Champaran district of Bihar led to the Champaran Satyagraha of 1917, a major revolt in the Indian Independence Movement.
* The Martand Sun Temple built in the 8th century in Anantnag was completely destroyed on the orders of Muslim ruler Sikandar Butshikan in the early 15th century.
* Bollywood director Vishal Bhardwaj is known for his admiration of William Shakespeare's works. "Haider" is the Indian adaptation of Hamlet while Maqbool is based on Macbeth and Omkara on Othello.
* Most criminal defendants, in Japan or elsewhere, don’t have the option to simply exit their proceedings if they believe they can’t win. Carlos Ghosn—with ample financial resources and passports from Lebanon, France, and Brazil—did. An elite extraction team led by Michael Taylor, ex-Green Beret turned security contractor, spirited the former CEO of Nissan Motor Co. and Renault SA, out of Japan by studying hotel layouts and airport security. Ghosn’s passports had been taken as a condition of his bail—with one exception. He had two French passports, a privilege granted to citizens with particularly demanding travel schedules. He’d received permission to keep the second one; Japanese law requires foreigners to carry their identity documents at all times. As part of their reconnaissance, Taylor’s people had surveyed airports all over the country, looking for terminals where security was lax. The team observed that the X-ray machines in Kansai’s private terminal were much too small to scan a large box—and oversize items were simply waved through. The routine was the same on the night of Dec. 29. Airport officials didn’t examine the large black cases that Taylor and Zayek had with them, and they were loaded onto the Bombardier without incident. It landed at Istanbul’s Ataturk Airport about 12 hours later from where Ghosn took a second plane to Lebanon - Bloomberg
* The Rani of Jhansi Regiment was the Women's Regiment of the Indian National Army, the armed force formed by Indian nationalists in 1942 in Southeast Asia with the aim of overthrowing the British Raj in colonial India, with Japanese assistance. It was led by Dr. Lakshmi Swaminathan who came to be known as Captain Lakshmi & Lakshmi Sahgal. Sahgal was an atheist. Her body was donated to Ganesh Shankar Vidyarthi Memorial Medical College for medical research after she passed away at the age of 97.
