AWS S3 Object Lambda

 Amazon Announces S3 Object Lambda

Amazon has recently announced S3 Object Lambda, a new serverless feature to add customized code and process data from S3 before returning it to an application. S3 Object Lambda works with S3 GET requests and uses AWS Lambda functions to modify data as it is being retrieved from the object storage.

S3 Object Lambda is designed to add transparency to the consumer of the S3 objects with the clients receiving a modified version without interacting with another endpoint and without changes to an existing product.

The innovation of Onion Flats is important as buildings are responsible for 38% of global greenhouse gas emissions.

Firebase, Firestore


Firebase is a BaaS platform (Backend as a Service)
offering a wide variety of features and components for enhanced mobile and web application development. Firebase is preferred by many business owners and developers due to the level of usability it offers. Using the service reduces the need for users to develop APIs and manage servers. Firebase can also be customized based on the specific requirements of developers.

Firebase works with two different databases. The Real-Time Database is the original Firebase database product, and Cloud Firestore is a new and improved version of the Real-Time Database.

Cloud Firestore refers to a NoSQL cloud database that can be used to store and sync data for server-side and client-side programming purposes. Cloud Firestore facilitates flexible mobile, web, and server development. It can also be used for synchronizing data across real-time applications.

China's Digital Currency

 Anxiety in the US as China Creates the First Major Digital Currency

A thousand years ago, when money meant coins, China invented paper currency. Now the Chinese government is minting cash digitally, in a re-imagination of money
