WasmEdge in Kubernetes

WebAssembly meets Kubernetes with Krustlet - Microsoft Open Source Blog

WasmEdge in Kubernetes - WasmEdge Runtime

"Developers can leverage container tools such as Kubernetes, Docker and CRI-O to deploy, manage, and run lightweight WebAssembly applications. In this chapter, we will demonstrate how Kubernetes ecosystem tools work with WasmEdge WebAssembly applications.

Compared with Linux containers, WebAssembly could be 100x faster at startup, have a much smaller memory and disk footprint, and have a better-defined safety sandbox. However, the trade-off is that WebAssembly requires its own language SDKs, and compiler toolchains, making it a more constrained developer environment than Linux containers. WebAssembly is increasingly used in Edge Computing scenarios where it is difficult to deploy Linux containers or when the application performance is vital.

One of the great advantages of Linux application containers is the rich ecosystem of tools. The good news is that you can use the exact same tools to manage WebAssembly applications, enabling Linux containers and WebAssembly apps to run side-by-side in the same system."

Turbopack: Rust-based successor to Webpack

 Introducing Turbopack: Rust-based successor to Webpack – Vercel

With over 3 billion downloads, webpack is the current champion of the bundlers (though Vite has been rapidly advancing). Vercel found it too slow and has funded work on Turbopack. It's a project to keep an eye on and boasts huge performance boosts over webpack or even Vite, but there are some limitations to take into account:

3D web: Babylon.js vs. Three.js

 Why We Use Babylon.js Instead Of Three.js in 2022

WebGL, WebGPU, and 3D in general is one of these fundamental capabilities that has the most potential to push the web to the next level. Using these technologies directly, however, can be rather complex. In most cases, it makes sense to use a 3D web framework to speed up the development process. Today, there are two major open source frameworks that are capable enough to be considered seriously: Three.js and Babylon.js.

Twitter =?=> Mastodon

Mastodon (software) - Wikipedia

Mastodon is free and open-source software for running self-hosted social networking services. It has microblogging features similar to the Twitter service, which are offered by a large number of independently run nodes, known as instances, each with its own code of conduct, terms of service, privacy policy, privacy options, and moderation policies.^[6][7][8]

Each user is a member of a specific Mastodon instance (also called a server), which can interoperate as a federated social network, allowing users on different instances to interact with each other. This is intended to give users the flexibility to select a node whose policies they prefer, but keep access to a larger social network. Mastodon is also part of the Fediverse ensemble of server platforms, which use shared protocols allowing users to also interact with users on other compatible platforms,^[9] such as PeerTube and Friendica. Mastodon is crowdfunded and does not contain ads.

The Mastodon mascot is an animal with a trunk, resembling a mastodon or mammoth, sometimes depicted using a tablet or smartphone. Messages posted using the software were formerly known as "toots", although they are now simply called "posts".^[10] Mastodon was created by Eugen Rochko and announced on Hacker News in October 2016.^[11]

Lego-style hemp blocks for building a house

Amazing Lego-Style HEMP BLOCKS Make Building a House Quick, Easy & Sustainable - YouTube

These hempcrete blocks are a green building material made with a hemp-lime insulation mixture packed around a bio composite structural frame. 

They can be stacked like bricks to build walls up to 30 feet high and they become the insulation and the structure of the building. All you need to do after the walls are built is plaster the inside and outside, and then add windows, doors, and a roof! 

The hemp plant sequesters carbon during its growth, and lime, as it dries, reabsorbs the carbon that was released when it was manufactured, which means the hemp-lime mixture is carbon negative (it sequesters more carbon than it creates in its life cycle). 

Not only is this an environmentally friendly building material, it also creates a comfortable living space. The hempcrete helps to regulate temperature and humidity, it reduces noise transmission through the walls, it's fire-resistant, and it's non-toxic. This is an incredible green building technology and we can't wait to see Just BioFiber ramp up their block production so that we can start to see hempcrete buildings popping up all over the world.

libsql: fork of SQLite

by Founder and CEO of ChiselStrike. Join me! https://github.com/chiselstrike/chiselstrike.

GitHub - libsql/libsql: libSQL is a fork of SQLite that is both Open Source, and Open Contributions.

libSQL is an open source, open contribution fork of SQLite. We aim to evolve it to suit many more use cases than SQLite was originally designed for.

We want to see a world where everyone can benefit from all of the great ideas and hard work that the SQLite community contributes back to the codebase. Community contributions work well, because we’ve done it before. If this was possible, what do you think SQLite could become?

SQLite is gaining ground in edge use cases, since it is fast, embeddable, and matches well the read-mostly, low-to-medium volume of data use cases that often arise at the edge. But there is still the problem of how to make the data available in all nodes.

That is challenging to do without support from the core database. Without proper hooks, existing solutions either build a different database around SQLite (like dqlite, rqlite, ChiselStore), or have to replicate at the filesystem layer (LiteFS).

What if we could do it natively?

SQLite does support user-defined functions. But there are two big problems with how they are approached: first, functions are written in C, which is increasingly becoming a tall ask for most developers with safety in mind. WASM is growing in popularity, allowing developers to write functions in their preferred language and be safely executed.

HTML template element

unnecessary "simplicity?"

Templating in HTML | Kitty Giraudel

the <template> HTML element is intended to store HTML that is not yet used. The element itself and all its content are invisible, so it can be basically anywhere in the document without much risk.

<template> do not enabling you to do anything that’s not possible otherwise. In that way, it’s more of a convenience tool really. If you have significant HTML structures that need to be injected at runtime

Why not a hidden element?

Unlike content within a hidden container, the content of a <template> is inert: images and scripts do not load, styles do not apply, elements are not queried, etc.
