Matteo Technical Principles

1. Conway’s Law is paramount.

Any organization that designs a system (defined broadly) will produce a design whose structure is a copy of the organization's communication structure.

In order to design a piece of software we need to “design” the team that is going to produce it.

2. Developer Experience is key to productivity

A compile-time 4-Bit Virtual Machine implemented in TypeScript's type system. Capable of running a sample 'FizzBuzz' program.

Syntax emits zero JavaScript.

type RESULT = VM<
  [
    ["push", N_1],         // 1
    ["push", False],       // 2
 ["peek", _], // 3

The history of hyperHTML followed by lit-html

While many remember the epic hyperHTML: A Virtual DOM Alternative post I've published the 5th of March 2017, the first official implementation of the library was working as hyperHTML.bind(node) function for tagged literals the day before, and it's been in my experiments folder already for a little while.

The hilarious reaction from the skeptical community

At first glance people couldn't believe performance of the DBMonster demo shown in that article,

	import {Readable} from 'node:stream';
	import {TextDecoderStream} from 'node:stream/web';
	import {spawn} from 'node:child_process';

	const childProcess = spawn(
	'echo', ['hello world'],
	{
	stdio: ['ignore', 'pipe', 'inherit'],
	}
	);

	<link rel="shortcut icon" width=32px>
	<canvas style="display: none" id="loader" width="16" height="16"></canvas>

	<script>
	class Loader {
	constructor(link, canvas) {
	this.link = link;
	this.canvas = canvas;
	this.context = canvas.getContext('2d');
	this.context.lineWidth = 2;

	import { defineAsyncComponent } from 'vue'

	const Content = defineAsyncComponent(() => import('./component-content.js'))

	export default {
	name: 'App',
	components: { Content },
	template: /html/`
	<Content />
	`

	export const h=(t,p,...c)=>({t,p,c,k:p&&p.key})
	export const render=(e,d,t=d.t\|\|(d.t={}),p,r,c,m,y)=>
	// arrays
	e.map?e.map((e,p)=>render(e,d,t.o&&t.o[p])):
	// components
	e.t.call?(e.i=render((render.c=e).t(Object.assign({children:e.c},e.p),e.s=t.s\|\|{},t=>
	render(Object.assign(e.s,t)&&e,d,e)),t.i\|\|d,t&&t.i\|\|{}),d.t=t=e):(
	// create notes
	m=t.d\|\|(e.t?document.createElement(e.t):new Text(e.p)),
	// diff props

	const os = require('os')
	const crypto = require('crypto')
	const path = require('path')
	const fs = require('fs')
	const util = require('util')
	const puppeteer = require('puppeteer')
	const libxml = require('libxmljs')
	const dayjs = require('dayjs')

	// generates static html files for server side rendering
