Simple Python UDP echo server

	#!/usr/bin/env python3
	# -- coding: utf-8 --

	# Author: David Manouchehri <[email protected]>
	# This script will always echo back data on the UDP port of your choice.
	# Useful if you want nmap to report a UDP port as "open" instead of "open\|filtered" on a standard scan.
	# Works with both Python 2 & 3.

	import socket

Calculate the blast radius of a shuffle shard

	import sys

	# choose() is the same as computing the number of combinations. Normally this is
	# equal to:
	#
	# factorial(N) / (factorial(m) * factorial(N - m))
	#
	# but this is very slow to run and requires a deep stack (without tail
	# recursion).

Quick and dirty DDNS using Bash and Cloudflare (API v4 compatible)

	#!/usr/bin/env bash

	# Step 1: Fill in EMAIL, TOKEN, DOMAIN and SUBDOMAIN. Your API token is here: https://www.cloudflare.com/a/account/my-account
	# Make sure the token is the Global token, or has these permissions: #zone:read, #dns_record:read, #dns_records:edit
	# Step 2: Create an A record on Cloudflare with the subdomain you chose
	# Step 3: Run "./ddns.sh -l" to get the zone_id and rec_id of the record you created.
	# Fill in ZONE_ID and REC_ID below
	# This step is optional, but will save you 2 requests every time you this script
	# Step 4: Run "./ddns.sh". It should tell you that record was updated or that it didn't need updating.
	# Step 5: Run it every hour with cron. Use the '-s' flag to silence normal output
