Google Meet vs Zoom

Google Meet, Google’s Zoom competitor, is now free for everyoneGoogle Meet, Google’s Zoom competitor, is now free for everyone | Ars Technica

Google Meet, Google's newest video chat service, will soon be free for everyone. The service, which was previously locked behind G Suite, is opening up to anyone with a Google account.

Users will be able to access the service at or through the iOS and Android apps. While the service's free tier is unrestricted now, it won't be unrestricted forever. Google says that, after September 30, meetings for non G Suite accounts will be limited to 60 minutes.

Do I need to install anything?
For users on Chrome, Firefox, Safari and new Edge we don't require or ask for any plugins or software to be installed, Meet works entirely in the browser. This limits the attack surface for Meet and the need to push out frequent security patches on end-user machines. On mobile, we ask that you install the Meet app from Apple App Store or the Google Play Store

Zoom Vulnerabilities with Patrick Wardle - Software Engineering Daily
Zoom’s rapid growth in user adoption came from its focus on user experience and video call quality. This focus on product quality came at some cost to security quality. As our entire digital world has moved onto Zoom, the engineering community has been scrutinizing Zoom more closely, and discovered several places where the security practices of Zoom are lacking.

Node.js with WebAssembly (WASM+WASI)

Node.js version 14 available now - Node.js - Medium

Packages written in Web Assembly for Node.js bring the opportunity for better performance and cross-platform support for certain use cases. The 14.x release includes an experimental implementation of the Web Assembly System Interface (WASI) in order to help support these use cases. While not new to Node.js v 14, this is noteworthy as WASI has the potential to significantly simplify the native modules experience

VS Code dev in container

Developing inside a Container using Visual Studio Code Remote Development

"The Visual Studio Code Remote - Containers extension lets you use a Docker container as a full-featured development environment. It allows you to open any folder inside (or mounted into) a container and take advantage of Visual Studio Code's full feature set. A devcontainer.json file in your project tells VS Code how to access (or create) a development container with a well-defined tool and runtime stack. This container can be used to run an application or to sandbox tools, libraries, or runtimes needed for working with a codebase.

Workspace files are mounted from the local file system or copied or cloned into the container. Extensions are installed and run inside the container, where they have full access to the tools, platform, and file system. This means that you can seamlessly switch your entire development environment just by connecting to a different container."

Waymo: the end of AutoPilot

Why Waymo Gave Up On Driver-Monitored Autopilot | CleanTechnica

"Around 6 months after Tesla’s Autonomy Day, Waymo CEO John Krafcik gave a presentation to German auto giants that he was seeking to partner with. A video clip of this presentation, provided by Third Row Tesla, shows the CEO explaining why Waymo shut down their “Autopilot program.”
Third Row Tesla Podcast on Twitter: "On autonomy day, @elonmusk hit Waymo pretty hard revealing to the world for the first time that their project was bound to fail. 6 months later, Waymo hit Tesla back in a presentation to the German auto giants, who he seeked to partner with.

"Bidirectional Encoder Representations from Transformers (BERT) is a technique for NLP (Natural Language Processing) pre-training developed by Google. BERT was created and published in 2018 by Jacob Devlin and his colleagues from Google.[1][2] Google is leveraging BERT to better understand user searches.[3]"

BERT Encoder

The BERT Encoder block implements the BERT—​Bidirectional Encoder Representations from Transformers—​network in its base size, as published in BERT: Pre-training of Deep Bidirectional Transformers for Language Understanding.
BERT pushes the state of the art in Natural Language Processing by combining two powerful technologies:
  • It is based on a deep Transformer encoder network, a type of network that can process long texts efficiently by using attention.
  • It is bidirectional, meaning that it uses the whole text passage to understand the meaning of each word.

AI: Stephen Wolfram: A New Kind of Science: computation

AI Lex: Stephen Wolfram: Cellular Automata, Computation, and Physics | MIT | Artificial Intelligence Podcast

Stephen Wolfram is a computer scientist, mathematician, and theoretical physicist who is the founder and CEO of Wolfram Research, a company behind Mathematica, Wolfram Alpha, Wolfram Language, and the new Wolfram Physics project. He is the author of several books including A New Kind of Science

As a businessman, he is the founder and CEO of the software company Wolfram Research where he worked as chief designer of Mathematica and the Wolfram Alpha answer engine. His recent work has been on knowledge-based programming, expanding and refining the programming language of Mathematica into what is now called the Wolfram Language.

Since its nascent beginnings in the 1930s, computation has been primarily approached from two traditions: engineering, which seeks to build practical systems using computations; and mathematics, which seeks to prove theorems about computation.

Wolfram introduces a third tradition that seeks to empirically investigate computation for its own sake: he argues that an entirely new method is needed to do so because traditional mathematics fails to meaningfully describe complex systems, and that there is an upper limit to complexity in all systems.[4]

Game of Life

Conway's Game of Life - Wikipedia

The Game of Life, also known simply as Life, is a cellular automaton devised by the British mathematician John Horton Conway in 1970.[1]

The game is a zero-player game, meaning that its evolution is determined by its initial state, requiring no further input. One interacts with the Game of Life by creating an initial configuration and observing how it evolves. It is Turing complete and can simulate a universal constructor or any other Turing machine.

AWS ElastiCache Global

Amazon Introduces a New Feature for ElastiCache for Redis: Global Datastore

With the Global Datastore, Amazon delivers a feature to its ElastiCache for Redis following customer demand for replication of clusters across AWS regions. Writing data into ElastiCache for a Redis cluster in one region leads to the data available for reading in two other cross-region replica clusters when creating a Global Datastore – thus enabling low-latency reads and disaster recovery across regions.

"Amazon EventBridge is a serverless event bus that makes it easy to connect applications together using data from your own applications, integrated Software-as-a-Service (SaaS) applications, and AWS services. EventBridge delivers a stream of real-time data from event sources, such as Zendesk, Datadog, or Pagerduty, and routes that data to targets like AWS Lambda."

Schema Registry ... stores event structure - or schema - in a shared central location and maps those schemas to code for Java, Python, and Typescript so it’s easy to use events as objects in your code. Schema from your event bus can be automatically added to the registry through the schema discovery feature. You can connect to and interact with the schema registry from the AWS Management Console, APIs, or the SDK Toolkits for Jetbrains (Intellij, PyCharm, Webstorm, Rider) and VS Code.

Nassim Taleb: Covid is not a "Black Swan"

meaning it was predictable

The Corona Crisis is Not a Black Swan: Nassim Nicholas Taleb (Universa Inv. & NYU Tandon) - YouTube

Our tightly networked world: Blessing and curse | American Enterprise Institute - AEI

The risks of such rare, concerning events are of course especially on our minds today in the context of Covid-19. Taleb anticipated this in a supplemental essay he wrote for the paperback edition of The Black Swan when it appeared in 2010: 

“As we travel more on this planet, epidemics will be more acute—we will have a germ population dominated by a few numbers, and the successful killer will spread vastly more effectively.

Taleb-Advised Universa Tail Fund Returned 3,600% in March - Bloomberg

"A tail-risk hedge fund advised by Nassim Taleb, author of “The Black Swan,” returned 3,612% in March, paying off massively for clients who invested in it as protection against a plunge in stock prices."

Clojure (Lisp): the "last" programming language?

Clean Coders: Clean Code, Episode 0 - The Last Programming Language, by Robert "Uncle Bob" Martin

"Are there any more types of languages that we haven't seen? Or have we completely explored the language space? And if we have, then isn't it time we pruned the menagerie of languages down to a manageable few—perhaps even one?

Other industries have done this, so why not us? Others disciplines have brought their notations down from dozens to one: electronics, chemistry, biology, mathematics, etc. And the benefits they reaped by doing so were significant! Perhaps it's time for us to follow suit.

If we did choose a language, what kind of language would it be? What features would it have? What syntax would it follow? What paradigms would it conform to?"

Tone.js Interactive Music Web Framework

Tone.js leverages the Web Audio API to provide a framework for creating interactive music in the browser.
The Web Audio API is a promising W3C recommendation for creating music on the web, but is not without its challenges and limitations. Tone.js strives to provide a framework that is familiar to both musicians and audio programmers for creating web-based audio applications.
Tone.js offers a wide range of digital audio workstation (DAW) features, including scheduling events, prebuilt synths and effects, and more. Tone.js provides an abstraction on top of Web Audio's AudioContext time, replacing seconds with music notes or measures.

"no code" & clouds

Salesforce logo.svgNew Microsoft, Google, Amazon cloud battle over world without code

“There is a 1 million developer shortfall in the U.S. alone, and all these companies are struggling to create content and applications to go truly digitally native"
Salesforce created a (cloud) empire based on "no-software".

That was 20 years ago.
The meaning was: no download & install, just run on web/cloud.

Now again, major cloud provides are attempting to enable
faster creating of "apps" (software), without need for
programming "low level" instructions: code. “Behind the cloud”, shines the sun – Kasper Spiro

TypeScript: Typed JavaScript at Any Scale.


Grady Booch, author of Object-Oriented Analysis and Design with Applications:

"Clean code is simple and direct. Clean code reads like well-written prose. Clean code never obscures the designers’ intent but rather is full of crisp abstractions and straightforward lines of control."

“code that you cannot trust is code that you do not understand.
The reverse is true also: code that you don’t understand is code you can’t trust.”

YAGNI Martin Fowler

Yagni originally is an acronym that stands for "You Aren't Gonna Need It".
It is a mantra from ExtremeProgramming that's often used generally in agile software teams.
It's a statement that some capability we presume our software needs in the future
should not be built now because "you aren't gonna need it".
