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('https://jsonplaceholder.typicode.com/posts').then(r => r.json())

and to make result data nicely formatted as a table:

await fetch('https://jsonplaceholder.typicode.com/posts').then(r => r.json()).then(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 Socket.io, 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."

Amundsen : Lyft’s data discovery & metadata engine

lyft/amundsenfrontendlibrary: Front-end service library for Amundsen @ GitHub

"Think of it as Google search for data.
The project is named after Norwegian explorer Roald Amundsen,
the first person to discover South Pole."

It includes three microservices and a data ingestion library.

• amundsenfrontendlibrary: Frontend service which is a Flask application with a React frontend.
• amundsensearchsearchlibrary: Search service, which leverages Elasticsearch for search capabilities, is used to power frontend metadata searching.
• amundsenmetadatalibrary: Metadata service, which leverages Neo4j as the persistent layer, to provide various metadata.
• amundsendatabuilder: Data ingestion library for building metadata graph and search index. Users could either load the data with a python script with the library or with an Airflow DAG importing the library.

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."

Uber is running private data centers, not using public cloud
It is also not using Kubernetes, instead has has developed its own cluster scheduler.
It is moved from node.js to GoLang for performance.
It has also moved from Posgres to MySQL, and running "schemaless" datastore.
It has a LOT of data, and running ML on that.

Amazon drone + hot air balloon patent

Amazon hot air balloon Prime Air patent describes stealthy delivery drones - SlashGear

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

“unmanned aerial vehicle with inflatable membrane” would have a balloon hidden inside the chassis. That could be inflated using compressed gas, via a tank or chamber also carried on the drone. 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."

Why the Lean Start-Up Changes Everything @ HBR
by Steve Blank

• "First, rather than engaging in months of planning and research, entrepreneurs accept that all they have on day one is a series of untested hypotheses—basically, good guesses.
• Second, lean start-ups use a “get out of the building” approach called customer development to test their hypotheses.
• Third, lean start-ups practice something called agile development,"

WebAssembly System Interface: WASI

Mozilla Announces WASI Initiative to Run Web Assembly on All Devices, Computers, Operating Systems

"WebAssembly System Interface (WASI), defines one single conceptual operating system interface, which can be implemented by multiple, actual operating systems.

The WASI standard will strive to provide WebAssembly's portability and security through a modular set of standard interfaces, and to provide a solid foundation for an ecosystem. Mozilla and Fastly are already shipping prototypal WASI implementations."

"...creating a WebAssembly instance for each of the tens of thousands of requests per second in a single process, which requires a dramatically lower runtime footprint than possible with a browser JavaScript engine. Lucet can instantiate WebAssembly modules in under 50 microseconds, with just a few kilobytes of memory overhead. By comparison, Chromium’s V8 engine takes about 5 milliseconds, and tens of megabytes of memory overhead, to instantiate JavaScript or WebAssembly programs."
