Verified Spec-Driven Development (VSDD)

The Fusion: VDD × TDD × SDD for AI-Native Engineering

Overview

Verified Spec-Driven Development (VSDD) is a unified software engineering methodology that fuses three proven paradigms into a single AI-orchestrated pipeline:

Spec-Driven Development (SDD): Define the contract before writing a single line of implementation. Specs are the source of truth.
Test-Driven Development (TDD): Tests are written before code. Red → Green → Refactor. No code exists without a failing test that demanded it.

Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

Manage services in systemd, openRC and runit

systemd

list all services: systemctl list-unit-files
list running services status: systemctl list-units
list failed services: systemctl --failed
list available services: systemctl --all
start a service: systemctl start [SERVICE_NAME]
stop a service: systemctl stop [SERVICE_NAME]

QueryExtensions

First, you'll need to incorporate the extension:

class ApplicationRecord < ActiveRecord::Base
  extend QueryExtensions
end

Arel Cheatsheet on Steroids

A (more) complete cheatsheet for Arel, including NamedFunction functions, raw SQL and window functions.

Tables

posts = Arel::Table.new(:posts)
posts = Post.arel_table # ActiveRecord

Vue: Pass Slots through from Parent to Child Components

The Situation

We've got some components A, B and C which provide different slots.

const A = {
  template: `<div><slot name="a">Default A Content</slot></div>`
}

const B = {

	class Cond
	IDENTITY = -> v { v }

	def initialize(if_cond: IDENTITY, then_branch: IDENTITY, else_branch: IDENTITY)
	@if_cond = if_cond
	@then_branch = then_branch
	@else_branch = else_branch
	end

	def call(v)
