This Week I Learned - Week #241

This Week I Learned -

* Lambda runs a customer’s line of code in response to a request, like looking up a ZIP code when given an address. Customers never rent servers, but pay for the moments of computing. The per-millionth pricing began last November, in the A.W.S. product Lambda. At Amazon Web Services, which pioneered this method late last year, there is no charge for the first million times a customer runs code. Thereafter, A.W.S. charges by the million times, or for the hundreds of milliseconds the computer is used. Google charges pennies for search ads and spends $9.9 billion annually building out a global computing business. Good luck to any new entrant without the scale of these tech giants, however, as customers come to expect that sort of cheap metering. This economics of tiny things demonstrates the global power of the few companies, including Microsoft and Google, that can make fortunes counting this small and often - NY Times

* A Cloud Guru website's Salesforce 101 course provides a high level overview of Salesforce products


* CIFS is a particular implementation of the Server Message Block protocol, created by Microsoft. In the Windows world, SMB 2 has been the standard as of Windows Vista (2006) and SMB 3 is part of Windows 8 and Windows Server 2012. NFS stands for “Networked File System.” It was developed by Sun Microsystems and serves essentially the same purpose as SMB (i.e., to access files systems over a network as if they were local), but is an entirely different protocol. This means that NFS clients can’t speak directly to SMB servers.

* Service Integration and Management (SIAM) is an approach to managing multiple suppliers of services (business services as well as information technology services) and integrating them to provide a single business-facing IT organisation.

* Those cookie-based ads and targeted emails reminding you of other possibilities reinforce the paradox of choice, the oft-cited theory of Barry Schwartz, the psychologist, that increased options leave us more dissatisfied.This reduction of cognitive dissonance is easier inside and after leaving a store, which never reveals anything negative about its products and doesn’t typically burden the consumer with an onslaught of information that might impede an impulse purchase. But the sprawling internet bazaar is filled with scathing critiques, and every pertinent spec exists somewhere online for the diligent buyer to seek out. That one-star rating is hard to forget when your product is failing in the exact way the unhappy reviewer described - NY Times

* It is possible to show sets of locations selectively on a custom map using the Layers with the Google My Maps feature

* In Germany, that long term data analysis (of applicant data, statistics)...isn't allowed...You may not gather personal data and you have to delete personal data when you rejected the candidate.

TED Translators program launched in 2009, with 300 translations in 40 languages, created by 200 volunteer translators. Today, more than 120,000 translations have been published in 115 languages (and counting), created by more than 28,000 volunteers. In 2012, the program expanded to include the transcription and translation of TEDxTalks, the translation of TED-Ed lessons and the translation of content distributed by worldwide partners who help grow TED’s global footprint. TED Translators use a free online subtitling tool called Amara to subtitle talks and collaborate with other volunteers.

* Kathy Gibson runs the website Access Bollywood which presents Hindi film reviews from an American moviegoer's perspective. She tailors her reviews toward Westerners, highlighting details and subtitling issues that may make certain films harder to understand than others.
* Amazon Video describes Mani Ratnam's Kannathil Muthamittal / A Peck on the Cheek as a Bollywood musical

* The Make in India program has a target of getting manufacturing to account for 25% of GDP by 2022

* Android permission called “Activity Recognition” makes it much easier for developers to work out what you’re doing at any one time. Shazam and SoundHound request the permission, but it isn’t completely clear why. Activity Recognition can tell developers when your phone is: in a vehicle, such as a car; on a bicycle; not moving; being tilted, due to its angle “relative to gravity” changing; on a user who’s walking or on a user who’s running. The API automatically gives its findings a likelihood rating out of 100. The higher the number, the more confident it is that you’re actually doing what it believes you’re doing. This information is fed to the apps you’ve granted the Activity Recognition permission to - The Independent

* Aadhaar Act (Targeted Delivery of Financial and Other Subsidies, Benefits and Services) Act, 2016 does not require an Aadhaar number as a mandatory requirement for availing any subsidy, benefit or service.

* The validity of Aadhaar law that has been challenged by a number of people, including former Karnataka High Court Judge KS Puttaswamy, first Chairperson of National Commission for Protection of Child Rights and Magsaysay awardee Shanta Sinha and researcher Kalyani Sen Menon - Zee News

* A value greater than 150 on the Air Quality Index is unhealthy

* The Geography Now channel on YouTube has lighthearted and informative videos on countries around the world
