* A landing zone is an environment for hosting your workloads, preprovisioned through code. Azure landing zones provide cloud adoption teams with implementation options for a well-managed environment for their workloads.
* Automating ML monitoring and re-training is an important part of MLOps. The accuracy of ML models can deteriorate over time, a phenomenon known as model drift. Many factors can cause model drift, such as changes in model features. Concept drift can also affect your models, and if you have 100’s of them deployed to production, the good news is that you can use Amazon Sagemaker Pipelines’ workflow automation components to build operational resilience and reproducibility.
* Clarity, a behavioral analysis tool that helps you understand user experience.

* Opinion - There is no specific and direct provision for taxation of withdrawal from Tier II account under the Income Tax Act. If tax law does not have any specific provisions for taxation of an item, it does not by default becomes tax-free or taxable. Since the investment made in Tier II account does not carry any fixed rate of return like fixed deposits or bonds or debenture, the appreciation in the value of investments cannot be taxed under the head “Income from other sources". As a subscriber is allotted units for his investments in different categories of funds like of equity, corporate bonds and government securities at their Net Asset Value (NAV) at the time of investment, it is logical to treat contribution to tier II account as investments and treat any profits thereon as capital gains.
* The Central Recordkeeping Agency (CRA) charges for NPS tier II account are levied on a quarterly basis. The bill amount is recovered by way of redemption of units on the last working day of the quarter & can be viewed in the Statement of Holding. CRA follows the (T+3) Settlement Cycle.

* Former State Bank of India Chairman Pratip Chaudhuri was arrested on Sunday from his Delhi home in an alleged loan scam case related to a hospitality group in Jaisalmer in 2008 amounting to Rs 24 crore. Chaudhuri's tenure as the 23rd Chairman of SBI ended in September 2013. He later joined Alchemist ARC as Director. After the account became an non-performing asset (NPA) in 2010, SBI had assigned the recovery of loans associated with the hotel project to Alchemist ARC in March 2014. In December 2017, a non-banking finance company (NBFC) bought the hotel project under the Insolvency and Bankruptcy Code. Chaudhuri was the face of SBI's recovery efforts against Kingfisher Airlines in 2012-13, when banks had recognised the account as a non-performing asset.

She was given the Padma Shree by the President of India in 2005 for her service to the cause of public affairs.

* Colonel Richard Meinertzhagen, was a British soldier, intelligence officer, and ornithologist. While early biographies lionized Meinertzhagen as a master of military strategy and espionage, later works such as The Meinertzhagen Mystery present him as a fraud for fabricating stories of his feats and speculated he was also a murderer. He is frequently credited with a surprise attack known as the Haversack Ruse in October 1917; during the Sinai and Palestine Campaign of the First World War, according to his diary, he let a haversack containing false British battle plans fall into Ottoman military hands, thereby bringing about the British victory in the Battle of Beersheba and Gaza. The true author of the ruse, Lt Col Belgrave, had never contradicted Meinertzhagen's account because he was killed in action on 13 June 1918. The ruse inspired Winston Churchill to create the London Controlling Section, which planned countless Allied deception campaigns during the war, and such operations as Mincemeat and diversions covering D-Day were influenced by the Haversack Ruse. Salim Ali noted Meinertzhagen's special hatred for Mahatma Gandhi and his refusal to believe that Indians could govern themselves.
* Elon Musk graduated from University of Pennsylvania in 1997 with a Bachelor of Science degree in economics and a Bachelor of Arts degree in physics.

In March 2000, Elon Musk's x.com, an online financial services company founded in March 1999 merged with Confinity/Paypal, founded by Peter Thiel, Luke Nosek and Max Levchin. Musk's preference for Microsoft software over Linux created a rift in the company and caused Thiel to resign. In 2002, PayPal was acquired by eBay for $1.5 billion in stock, of which Musk—the largest shareholder with 11.7%—received over $100 million.
