This Week I Learned -
* The spoke virtual networks can be hosted in the same or a different Azure subscription with respect to the hub virtual network and they are used to isolate workloads from one another. The benefits of using a hub and spoke configuration include cost savings, overcoming subscription limits, and workload isolation.
* Neat compilation of resources for Azure VMware Solution (AVS)
* According to Gartner, the root cause of 90% of cloud-based availability issues will be the failure to fully use cloud service provider native redundancy capabilities.
* In the detailed preceding ML Lifecycle diagram, the red boxes represent comparatively newer concepts and tasks that are now deemed important to include in, and run in a scalable, operational, and production-oriented (vs. research-oriented) environment.
* From the buzzword factory - DataOps, MLOps, ModelOps and PlatformOps, which comprise XOps, are necessary to achieve efficiencies and economies of scale through DevOps and using best practices of reliability, reusability and repeatability. This also reduces duplication of technology and processes and enabling automation.
* Accellion, a privately held company based in Palo Alto, California, developed the File Transfer Appliance as a secure way to overcome limits imposed on the size of email attachments. Recipients get links to files hosted on the FTA, which can then be downloaded. The product is nearly 20 years old, yet it's still used by hundreds of organizations in the finance, government and insurance sectors to transfer sensitive files. Accellion prides itself on secure file sharing, so the appliance – given its age and wide use – is a juicy target. Several data breaches stemming from unpatched vulnerabilities in Accellion's File Transfer Appliance (FTA) have been revealed. New Zealand's Reserve Bank is one victim of a breach involving Accellion's FTA product. Accellion has stated that Kiteworks, its enterprise content firewall platform was not affected by the attacks.
* creativecommons.org & Unsplash offer free images that can be used commercially. They also provide APIs to programmatically access these images.
* 2018 Kindle Paperwhite is rated IPX8, meaning it can sit in 2 meters of water for two hours. The Amazon Kindle Oasis (2019) is more expensive than two Kindle Paperwhites. The Kindle Kids Edition includes a two-year no-questions-asked replacement guarantee. If your kid smashes it just once, you get your money back.
* Twitter CEO Jack Dorsey listed his first-ever tweet as an NFT. NFT stands for "nonfungible token." Nonfungible, meaning you can't exchange it for another thing of equal value. A $10 fungible bill can be exchanged for two $5 bills. An NFT, though, is one of a kind. The token refers to a unit of currency on the blockchain. It's how cryptocurrency like Bitcoin is bought and sold. When you buy an NFT, you're usually not getting the copyright or trademark to the item. It is a certificate of authenticity that serves as proof that a certain version of something is uniquely yours.
* Bill Gross started Idealab with a dream to make something like a modern version of Thomas Edison’s Lab where he could test ideas under one roof and then spin them off into separate companies. Idealab came up with more than 5,000 ideas, started more than 150 companies, and had more than 50 successful IPO’s and acquisitions and created more than 10,000 jobs in 25 years.
* The tech savvy US air force had rejected the stealth technology initially when it was developed by DARPA (Defense Research Advance Project Agency). Stealth was developed by Lockheed in it’s Skunk Works. The conception, funding and co-ordination was by DARPA. DARPA is NOT a research lab but a funding agency.
* Rockboard is a rigid, fire-resistant mineral wool insulation used for both acoustic and thermal insulation best used in residential and commercial buildings.
* Iridium, one of the rarest precious metals and mined as a byproduct of platinum and palladium, is 3 times expensive than gold
* Data fetishism is referred to as the phenomenon evolving when active users of self-tracking devices become enticed by the satisfaction and sense of achievement and fulfillment that numerical data offers. Proponents of such line of criticism tend to claim that data in this sense becomes simplistic, where complex phenomena become transcribed into reductionist data. The Quantified Self movement has been criticized for providing predetermined ideals of health, well-being and self-awareness. Rather than increasing the personal skills for self-knowledge, it distances the user from the self by offering an inherently normative and reductionist framework. The "know thy numbers to know thyself" slogan of the Quantified Self movement is inconsistent, it has been claimed, in the sense that it does not fully acknowledge the need for auxiliary skills of health literacy to actually get to "know thyself".
* Health professionals recommend that adults receive tetanus boosters at least every ten years, as preventing tetanus is much easier than curing it once infected. It isn’t the rust that causes the tetanus infection, but rather it’s a type of bacteria known as Clostridium tetani that is on the nail. Spores of this bacterium are ubiquitous in the natural environment — lurking in soil, dust, as well as in animal intestines and feces. In fact, the rusty nail scenario isn't the only way this disease spreads. Any deep puncture can become infected with Clostridium tetani, as can burns, torn flesh, punctures from needles during drug use, animal bites and scratches, or other wounds contaminated with human and animal feces or saliva. Once these spores find a way into the body, they grow into bacterium that can produce a toxin known as tetanospasmin, which spreads systemically throughout the body. This toxin interferes with motor neurons, the neurons that control the muscles, and can produce muscle stiffness, rigidity, or spasms. For those who suspect they’ve been exposed to tetanus, there are a number of symptoms to watch out for:
- Spasms and stiffness of jaw (hence why tetanus is commonly known as “lockjaw”)
- Muscle spasms — often in the abdomen
- Painful muscle stiffness throughout the body
- Trouble swallowing
- Restlessness and irritability
- Fever
- Headache
- Sore throat
- Changes in blood pressure or heart rate
* The tetanus vaccination works by causing an immune response in the body to an inactivated form of the tetanus toxin, thereby developing antibodies. In most cases, the vaccine is given to children as part of the diphtheria, tetanus, and pertussis (DTaP) shot. - Go Ask Alice!
* Mother India (1927) is a polemical book by American historian Katherine Mayo which attacks Indian society, religion and culture. Mayo's book Mother India was criticized by Mahatma Gandhi as a "report of a drain inspector sent out with the one purpose of opening and examining the drains of the country to be reported upon" but he also said that all Indians must read it and introspect. Annie Besant called Mother India "a remarkably wicked book slandering the whole Indian people". The book has also been cited as an example of feminist rhetoric being appropriated for advancing western imperialism and racism
* Pathala Bhairavi (1951) is the first ever Telugu film to gross over 1 crore.
* Chilika Lake in Odisha is Asia's largest brackish water lagoon and world's largest coastal lagoon.
* The Devanagari script, composed of 47 primary characters including 14 vowels and 33 consonants, is the fourth most widely adopted writing system in the world, being used for over 120 languages. It was developed in ancient India from the 1st to the 4th century CE and was in regular use by the 7th century CE. It is widely adopted across India to write Sanskrit, Marathi, Hindi and its dialects, and Konkani. Unlike the Latin alphabet, the script has no concept of letter case.
* During the 5th to 7th centuries CE the early Bādāmi Chālukyās and Early Banavasi Kadambās used an early form of the Kannada script in inscriptions, called the Kadamba script. The Kadamba script evolved into the Telugu-Kannada script, which was used between the 7th and 11th centuries CE. Kannada became a written language ahead of Telugu.
* Given the concept "Take it easy" by Kadhalan (1994) director Shankar, A R Rahman took three months to come up with first words "Urvasi Urvasi" for that song which went on to become a chartbuster.
* Talks at Google Anchor - Would you consider broadcasting your jam sessions just for people to get inside, into how you think and work?
A.R. Rahman - ...just that when you expose yourself too much, they don't want you
* "The more I learn about people, the more I like my dog." - Mark Twain
