Web Assembly: Wasmtime

Introduction - Wasmtime

"Wasmtime is a Bytecode Alliance project that is a standalone wasm-only optimizing runtime for WebAssembly and WASI. It runs WebAssembly code outside of the Web, and can be used both as a command-line utility or as a library embedded in a larger application.

Wasmtime strives to be a highly configurable and embeddable runtime to run on any scale of application."

bytecodealliance/wasmtime: Standalone JIT-style runtime for WebAssembly, using Cranelift @GitHub

You can use Wasmtime from a variety of different languages through embeddings of the implementation:

• Rust - the wasmtime crate
• C - the wasm.h, wasi.h, and wasmtime.h headers or use wasmtime Conan package
• [C++] - the wasmtime-cpp repository or use wasmtime-cpp Conan package
• Python - the wasmtime PyPI package
• .NET - the Wasmtime NuGet package
• Go - the wasmtime-go repository

Etzy: React => Preact

 Ben on Twitter: "We migrated all of the React v15.6 code at Etsy to use Preact. It was a huge win, and the migration was significantly easier (with far fewer rewrites or refactors of old code) than going to v16 would have been. The Preact team was amazing through the whole process." / Twitter

TypeScript compiler in GoLang

 I'm porting tsc to Go

"I’m porting the TypeScript Type Checker tsc to Go, and not Rust. As the creator of SWC, an extensible Rust platform, this might sound strange. Let me explain. ... rewriting a massive project such as tsc would be extremely difficult to continue.

• tsc: 133.2 seconds (TypeScript)
• Rust rewrite: 2.13 seconds (62x faster)

Vercel is sponsoring and funding the work to port tsc to Go.
planning to open-source this work in the future.

Ruby On Rails on Ubuntu on Windows 10

Thanks to WSL2: Windows Subsystem for Linux on Windows version 2, 
whole Linux (select distributions) can run "natively" on Windows,
transparently, without "virtual machines". 

With that, all Linux (unix) tools become directly usable.
Ruby on Rails installer takes full advantage of that, 
much simplifying possible compatibility issues.

server side Dart, with gRPC

Writing server side Dart code. …and: is it worth it? | by Matias Meno | Dropzone

Server side dart code is very similar to node. The simplest code to actually start an HTTP server in dart is this:

import 'dart:io';
main() async {
  final server = await HttpServer.bind(InternetAddress.anyIPv6, 80);
  server.listen((HttpRequest request) {
    request.response.write('Hello, world!');
    request.response.close();
  });
}

you compile your whole server app into a single binary, which is optimized and starts instantly, and ship it in a tiny Container.

 "a potential long-term rival for Ethereum", citing superior transaction speeds and lower associated costs.

Solana achieves consensus using a proof-of-stake mechanism, as well as a "proof-of-history" mechanism which Solana's whitepaper claims improves scalability without sacrificing decentralization and security.^[8]

Solana can handle 710,000 transactions per second, which is faster than the Ethereum blockchain

Etsy Moves from React to Preact to Lower Migration Risks

Etsy, recently announced the completion of Etsy’s migration from React v15.6 to Preact 10. Going beyond the difference in library size, Sangster argued that adopting Preact lowered the risk associated with migrating Etsy’s large codebase. As Preact was already used by Etsy’s front-end team, migrating to Preact for seller-facing pages would avoid maintaining a fragmented stack.
