Sandi Metz's blog post:

Make Everything The Same

Upon reading I decided to try an implement Sandi's concept before lookig at her code.

It wasn't worth a dime in comparison, but after reading her code, I decided to try and improvise from there.

Of course, this is no more than remixing the composition from a genius to feel your own style on it. But it was a interesting exercise. I opted for a module with no state and pure functions.

Exercise:

Given this calls:

Taskman.queue(2.5) { print 'world!' }
Taskman.queue(1.0) { print 'hello ' }

When we do this one:

Taskman.work

A very classy snake

I have the habit of start my coding musings by branching away from other people's proposals.

In this case I found myself looking at this video, where the author codes the snake game in 4'30''

The video is very good and the code is purposefully and relentlessly hacky. And the game indeed works after that time. While I was looking at it I was thinking, wow, I cannot beat him at his own game, but is it really so much different between that

Rails Boilerplate Script

This is a quick and dirty script to get going with Rails

Assumptions:

• Docker is installed
• Docker Compose is installed

window.Namespace = window.Namespace || {};

// Usage:
// Namespace.Rolenamee.init({ prop1: '.prop1', prop2: '.prop2' })
const Rolename = (function Rolename(expose) {
  // private class/constructor
  function Implementor({ foo, bar }) {
    this.foo = $(foo);         // store a value that will be needed asyncronously
    $(bar).on("event", () => { // set up an asyncronous reaction
      this.foo.method();       // use the stored value asyncronously through =>'s lexical `this`
