* The height of outsourcing - Businesses that use the WhatsApp Business app can send unsolicited messages. Once the message is received, it will be subject to the business’s own privacy practices. The business may designate a number of employees, or even other vendors, to process and respond to the message. While Facebook will not show your messages with businesses in anyone's personal Facebook account nor automatically use your messages to inform the ads that you see, businesses will be able to use chats they receive for their own marketing purposes, which may include advertising on Meta. You can always contact that business to learn more about its privacy practices.

*  Simple Object Access Protocol (SOAP) API standard can be significantly more verbose than REST and GraphQL, in part due to the usage of XML and because the standard includes more information, such as describing the XML namespace as part of the envelope system. This might be a reason why SOAP usage has declined for years.

* Building an ML model is one thing, but deploying it takes a completely different mindset and skillset.

A Princeton professor recently tweeted - "I mis-clicked on one of my 150 open tabs and it happened to be a tab that's been open since 2019 with a paper that has a solution to the exact research problem I've been puzzling over today. This is the moment I've been waiting for and I've decided to never close any tabs again". Going by the comments to that tweet, hoarding tabs is common phenomenon.  Edge browser kind of facilitates this behavior by conserving resources by "sleeping" open tabs that haven't been used recently.

However, in the case of Aadhaar, standards for data storage, sharing and transmission during collection are not available.

* Biometric authentication is essentially a method of image recognition (or pattern matching) and always results in a probabilistic score, rather than a clear match/mismatch

“RRR”—the title stands for “Rise Roar Revolt”—turns history into legend by way of heightened visual rhetoric. It’s based very loosely on the real-life stories of two Indian revolutionaries of the early twentieth century, Alluri Sitarama Raju and Komaram Bheem, who contested the oppressions of British colonial power. There’s no record of their having met, let alone joining forces. The director, S. S. Rajamouli—who also wrote the screenplay, based on a story by V. Vijayendra Prasad (his father)—derives a magnificent outpouring of creative energy from the inspiring fantasy of their volatile connection.  - The New Yorker

* Satyendranath Tagore, the brother of Rabindranath Tagore became India’s first civil servant in 1863.
