Use Linode's DNS Manager API for one-line dynamic DNS

This can be useful for cron, for instance.

Prereqs

• You are using Linode's DNS Manager to manage a zone for your domain
• You have already created an A record for the name you want to make dynamic
• You have an API key for Linode's API
• curl and jsonpp (jsonpp is not necessary but makes the manual steps easier)

// Run the function as soon as it's called, but prevent further calls during `delay` ms
// Example: function.throttle(200) will only run function() once every 200 ms.
// Useful, for example, to avoid constant processing while typing in a live search box.
Function.prototype.throttle = function(delay) {
  var fn = this
  return function() {
    var now = (new Date).getTime()
    if (!fn.lastExecuted || fn.lastExecuted + delay < now) {
      fn.lastExecuted = now
      fn.apply(fn, arguments)

How to setup Let's Encrypt for Nginx on Ubuntu 16.04 (including IPv6, HTTP/2 and A+ SLL rating)

There are two main modes to run the Let's Encrypt client (called Certbot):

• Standalone: replaces the webserver to respond to ACME challenges
• Webroot: needs your webserver to serve challenges from a known folder.

Webroot is better because it doesn't need to replace Nginx (to bind to port 80).

In the following, we're setting up mydomain.com. HTML is served from /var/www/mydomain, and challenges are served from /var/www/letsencrypt.

I have found this interesting for debugging, but also fun to hear web pages

Marsaglia-polar.js

This script generates random numbers along a Normal or Log-normal distribution using the Marsaglia polar method.

There are four functions you can use:

• normalRandom: Generate random numbers that follow a Normal distribution.
• normalRandomInRange: Generate random numbers that follow a Normal distribution but are clipped to fit within a range
• normalRandomScaled: Generate random numbers that follow a Normal distribution with a given mean and standard deviation
• lnRandomScaled: Generate random numbers that follow a Log-normal distribution with a given geometric mean and geometric standard deviation
