BRVTY - Ain't nobody got time for that

The first tool of my new startup “Fanlens” just got released! Train your own little pet robot
to filter your social media pages and communities!
Docker, by default, directly manipulates iptables
in order to work its network magic. It thus completely circumvents UFW rules! In this post I show strategies to deal with this.
In this post we’ll take a look at HyperLogLog, a probabilistic data structure that allows you to estimate the cardinality of huge data sets with minuscule memory requirements. This page is running an implementation JavaScript and uses 4kb to estimate a cardinality of up to 10,000,000 unique visitors based on 50,000,000 randomly generated visits.
This quick post started as a challenge to myself: “I wonder if I can bang out a k-means implementation with visualization from memory in less than 2 game of thrones episodes…” The result is an immutable, functional implementation in ES6 including a visualization in D3.js.
