An implementation of the Bjorklund algorithm in JavaScript

Inspired by the paper 'The Euclidean Algorithm Generates Traditional Musical Rhythms' 
by Godfried Toussaint

This is a port of the original algorithm by E. Bjorklund which I
found in the paper 'The Theory of Rep-Rate Pattern Generation in the SNS Timing Systems' by
E. Bjorklund.

{#
 time can be any string acceptable by http://www.php.net/strtotime, the
 template will output that time's month.

 If you don't want to pass in a date you can set time like this:
 {% set time = "now"|date("U") %}
 {% set time = "December 2012"|date("U") %}

 How ever you want to output items onto the calendar is a different issue,
 but I'd assume pushing everything into an array numerically indexed by that day:

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

console.log(" cos(2) = " + Math.cos(2));
console.log("-sin(2) = " + Math.sin(2));
console.log("(d cos/dx)(2) = " + derivative(Math.cos)(2));
 
function f(x) { return Math.pow(x, 3) + 2 * x + 1; };

Auto-deploying built products to gh-pages with GitHub Actions

This is a set up for projects which want to check in only their source files, but have their gh-pages branch automatically updated with some compiled output every time they push.

A file below this one contains the steps for doing this with Travis CI. However, these days I recommend GitHub Actions, for the following reasons:

• It is much easier and requires less steps, because you are already authenticated with GitHub, so you don't need to share secret keys across services like you do when coordinate Travis CI and GitHub.
• It is free, with no quotas.
• Anecdotally, builds are much faster with GitHub Actions than with Travis CI, especially in terms of time spent waiting for a builder.

Fundamentals: why state machines?

States. The final frontier. These are the voyages of an enterprising developer. Her eternal mission: to explore strange new techniques, to seek out better ways to engineer for mental models and new design patterns. To boldly go where a few awesome devs have gone before.

So you’ve found our poignant guide to SCXML and surely you’re wondering “Why should I want to go out of my way to use formal state machines?” or something like that. Hopefully this introduction addresses that kind of question.

An example: Nancy’s RPG

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
