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.

Cryptographic Best Practices

Putting cryptographic primitives together is a lot like putting a jigsaw puzzle together, where all the pieces are cut exactly the same way, but there is only one correct solution. Thankfully, there are some projects out there that are working hard to make sure developers are getting it right.

The following advice comes from years of research from leading security researchers, developers, and cryptographers. This Gist was [forked from Thomas Ptacek's Gist][1] to be more readable. Additions have been added from

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

Use NGINX as a Reverse Proxy

What is a Reverse Proxy?

A reverse proxy is a server that sits between internal applications and external clients, forwarding client requests to the appropriate server. While many common applications, such as Node.js, are able to function as servers on their own, NGINX has a number of advanced load balancing, security, and acceleration features that most specialized applications lack. Using NGINX as a reverse proxy enables you to add these features to any application. This guide uses a simple Node.js app to demonstrate how to configure NGINX as a reverse proxy.

Install NGINX

These steps install NGINX Mainline on Ubuntu 16.04 from NGINX official repository

Open /etc/apt/sources.list in a text editor and add the following line to the bottom. Replace CODENAME in this example with the codename of your Ubuntu release.

Adding a new user and password for a user

$ adduser demouser
$ passwd demouser

Double check the user file

$ vi /etc/demouser.conf

	First, install nginx for mac with "brew install nginx".

	Then follow homebrew's instructions to know where the config file is.

	1. To use https you will need a self-signed certificate: https://devcenter.heroku.com/articles/ssl-certificate-self
	2. Copy it somewhere (use full path in the example below for server.* files)
	3. sudo nginx -s reload
	4. Access https://localhost/

	Edit /usr/local/etc/nginx/nginx.conf:

	# Redis Cheatsheet
	# All the commands you need to know


	redis-server /path/redis.conf # start redis with the related configuration file
	redis-cli # opens a redis prompt


	# Strings.
