AWS App Runner & Copilot CLI for cloud containers

 449-introducing-aws-app-runner - AWS Podcasts

"AWS App Runner is a fully managed container application service that makes it easier and faster for customers to build, deploy, and run containerized web applications and APIs with just a few clicks, no infrastructure or containers experience required."


It is AWS Beanstalk with ECS/Faregate under the hood

448-aws-copilot-modern-applications-cli - AWS Podcasts

"Want to eliminate the heavy lifting of setting up infrastructure and deploying containerized applications to multiple environments? AWS Copilot CLI lets you build, deploy, and manage your containerized applications with a simple, well-organized set of commands. Then you can focus on application development while the CLI handles nuances of how AWS services integrate and manages all the steps required to deploy a container to the cloud!"

AWS Copilot CLI - AWS Copilot CLI

It is CloudFormation under the hood, with open source script CLI generating templates

interesting: it is written in GoLang, not in Python as AWS CLI is. 

GitHub - aws/copilot-cli: The AWS Copilot CLI is a tool for developers to build, release and operate production ready containerized applications on AWS App Runner, Amazon ECS, and AWS Fargate.

V8 "Sparkplug": fast JavaScript compiler

Chrome's JS V8 engine is getting faster, again... 

Sparkplug — a non-optimizing JavaScript compiler · V8

"Writing a high-performance JavaScript engine takes more than just having a highly optimising compiler like TurboFan. Particularly for short-lived sessions, like loading websites or command line tools, there’s a lot of work that happens before the optimising compiler even has a chance to start optimising, let alone having time to generate the optimised code."



"Sparkplug is designed to compile fast. Very fast. So fast, that we can pretty much compile whenever we want, allowing us to tier up to Sparkplug code much more aggressively than we can to TurboFan code.

There are a couple of tricks that make the Sparkplug compiler fast. First of all, it cheats; the functions it compiles have already been compiled to bytecode, and the bytecode compiler has already done most of the hard work like variable resolution, figuring out if parentheses are actually arrow functions, desugaring destructuring statements, and so on. Sparkplug compiles from bytecode rather than from JavaScript source, and so doesn’t have to worry about any of that.

The second trick is that Sparkplug doesn’t generate any intermediate representation (IR) like most compilers do. Instead, Sparkplug compiles directly to machine code in a single linear pass over the bytecode, emitting code that matches the execution of that bytecode. In fact, the entire compiler is a switch statement inside a for loop, dispatching to fixed per-bytecode machine code generation functions."

Rust => WASM @ Deno Server

Using Web Assembly Written in Rust on the Server-Side – The New Stack

this could be useful for "cloud functions @ edge"



WebContainers: Run Node.js as WebAssembly in web browser

Introducing WebContainers: Run Node.js natively in your browser


The advent of WebAssembly and new capabilities APIs made it seem possible to write a WebAssembly-based operating system powerful enough to run Node.js, entirely inside your browser.

WebContainers allow you to create fullstack Node.js environments that boot in milliseconds and are immediately online & link shareable—in just one click. The environment loads with VS Code's powerful editing experience, a full terminal, npm and more. It also runs entirely inside your browser

Grain: Your WebAssembly-First Programming Language vs AssemblyScript

Grain: Your WebAssembly-First Programming Language - WebAssembly Summit 2021

Grain is strongly typed (with a typechecker from OCaml), and its type inference significantly reduces the need for type annotations. Besides the WebAssembly core data types (e.g., i32 becomes Int32), Grain also provides composite types that are commonly used in high-level typed languages.


AssemblyScript, which compiles a strict variant of TypeScript to WebAssembly, also self-describes as made for WebAssembly and includes a standard library with common composite types (e.g., arrays, dates). Like Grain, AssemblyScript compiles to WebAssembly using Binaryen. AssemblyScript strives to give

Fuchsia OS

 Google finally starts pushing the new Fuchsia OS for the first-gen Nest Hub - Gizmochina

Google first commenced development of the Fuchsia OS in 2016, an open-source operating system that is distinctively not based on the Linux kernel, one major distinguishing feature from the Android OS. Instead of the Linux kernel, the OS is based on a microkernel called Zircon.







Fuchsia is an open-source capability-based operating system developed by Google. It first became known to the public when the project appeared on a self hosted form of git in August 2016 without any official announcement. The name means "Pink + Purple = Fuchsia (a new Operating System)",[2] which is a reference to Pink (Apple's first effort at an object-oriented, microkernel-based operating system) and Purple (the original iPhone's codename).[3] In contrast to prior Google-developed operating systems such as Chrome OS and Android, which are based on the Linux kernel, Fuchsia is based on a new kernel called Zircon. After years of development, Fuchsia was officially released to the public on the first-generation Google Nest Hub, replacing its original Cast OS.

DataOps

a "new buzzword"

DataOps - Wikipedia

"DataOps is an automated, process-oriented methodology, used by analytic and data teams, to improve the quality and reduce the cycle time of data analytics. While DataOps began as a set of best practices, it has now matured to become a new and independent approach to data analytics.[1] DataOps applies to the entire data lifecycle[2] from data preparation to reporting, and recognizes the interconnected nature of the data analytics team and information technology operations.[3]

DataOps incorporates the Agile methodology to shorten the cycle time of analytics development in alignment with business goals."

ReScript – the language after TypeScript? - codecentric AG Blog


"ReScript (formerly ReasonML) is the brainchild of React framework creator Jordan Walke. Although the language has only existed since 2016, an entire team is now working on its further development. Besides Facebook and financial giant Bloomberg, volunteer enthusiasts from all over the world are involved. It is therefore hardly surprising that the project has over 5,000 stars and almost 300 participants on GitHub and scores very well in surveys on developer satisfaction, as State Of JS shows. In the State of JS 2018 study, ReScript (at that time still called ReasonML) even won the prediction award – the award for emerging technologies.

Surprisingly, however, ReScript is not a completely new language. The underlying OCaml has been around since 1996, and Walke noticed that OCaml was a good fit for React, but the unfamiliar syntax put off many front-end developers. So he came up with the idea: How about giving the OCaml language a syntax that allows JavaScript developers to quickly find their way around? Thus, ReScript allows the concepts of a mature functional programming language with the popular Hindley-Milner type system to be transferred to the frontend in a very short time. This works surprisingly well: ReScript is relatively easy to learn for JavaScript and TypeScript developers. The language comes with an excellent type system, high performance and concepts from functional programming. For such a young language, there is also already relatively sophisticated tooling available.

Sidenote: OCaml and ReScript share the same roots as F# – another member of the ML-family which is great alternative in Microsofts .Net-ecosystem."

Ask HN: Who invented Base58 Encoding - Flickr or Bitcoin? | Hacker News


A commonly held view is that Satoshi Nakamoto invented Base58 encoding for Bitcoin: https://en.wikipedia.org/wiki/Base58

However, a Flickr discussion about Base58 encoded URLs exists from April 2009: https://www.flickr.com/groups/api/discuss/72157616713786392/

Did Flickr deploy their Base58 encoded URLs before the Bitcoin white paper was published on Oct 31, 2008?


recode uuid to shorter URL safe string, length: 36 => 22, i.e.
'1496c7cb-b4e4-4c84-954f-3da570e2e281' => '3xsFQ446662SRziHg4g3uZ'

import short from 'short-uuid';
