await fetch in Chrome dev tools console

Here is a simple way to get data from a web URL in Chrome dev tools console.
Since fetch() is an async function that returns a javascript promise, need to use await keyword, that is now supported by Chrome dev tools console.

await fetch('').then(r => r.json())
and to make result data nicely formatted as a table:

await fetch('').then(r => r.json()).then(console.table)

Chrome/Firefox console.table()

Ts.ED: TypeScript Web Server Framework

Ts.ED Provides TypeScript Framework Leveraging Express and Decorators

"Ts.ED provides a server-side TypeScript framework on top of Node.js and Express. The framework provides classes and decorators to simplify common server-side patterns, and offers integration with many other projects including TypeORM, Swagger, GraphQL, AJV, Passport.js, and, among others.

Ts.ED provides controllers using the @Controller decorator, each of which maps to Express' routing system. Similarly, decorators get provided for common patterns including requests, sessions, posts, middleware, server settings, and services.

To learn more about creating applications with Ts.ED, read the getting started with Ts.ED documentation and Ts.ED examples.

Ts.ED is open source software available under the MIT license. Contributions and feedback are encouraged via the Ts.ED GitHub project and should follow the Ts.ED contribution guidelines."

Google "Anthos": managed K8S for GCP, AWS, Azure, on premise

Google’s hybrid cloud platform is coming to AWS and Azure | TechCrunch

Anthos (supports) AWS and Azure as well, so people get one way to manage their application and that one way works across their on-premise environments and all other clouds

So with Anthos, Google will offer a single managed service that will let you manage and deploy workloads across clouds, all without having to worry about the different environments and APIs

Anthos/Google Cloud Services Platform is based on the Google Kubernetes Engine, as well as other open-source projects like the Istio service mesh. It’s also hardware agnostic, meaning that users can take their current hardware and run the service on top of that without having to immediately invest in new servers.

Anthos is a subscription-based service, with the list prices starting at $10,000/month per 100 vCPU block."

It has also moved from Posgres to MySQL, and running "schemaless" datastore.
It has a LOT of data, and running ML on that.

"Drones ... make a lot of noise. Amazon’s strategy is to combine some old-school hot air balloon technology to cut the noise pollution...

When the UAV roamed into an area where noise levels needed to be cut – such as the delivery location, Amazon suggests – the balloon could be inflated."
