Sun and Earth

Experiments faking 3d rotation of a globe and sun in SVG. Illusion is helped by dynamic gradients, two nested orthographic projections, scaling the sun circle's radius based on distance from the 'camera', and toggling a clipping mask that makes the sun appear to move "behind" the earth.

Based on Mike Bostock's Solar Terminator and this past experiment.

This example stems from drafts of maps for Norway the Slow Way. Also see Mike's Pencil Sketch example.

Clojure Destructuring Tutorial and Cheat Sheet

Clojure Destructuring Tutorial and Cheat Sheet

(Related blog post)

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

Vectors and Sequences

app.all('*', function (req, res, next) {
res.header("Access-Control-Allow-Origin", req.headers.origin);
res.header("Access-Control-Allow-Credentials", true);
res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE,OPTIONS');
res.header("Access-Control-Allow-Headers", "X-Requested-With, Content-Type, Authorization, Content-Length");
if (req.method == 'OPTIONS') {
return res.send(200);
}

The Shadow DOM Diaries

#The Shadow DOM Diaries

Feature design is hard, and takes time. With time, it doesn't matter how public and consistent you are with communication during design process. In the end, it all will look like a jumbled mess of emails and bug comments. That seems bad. To make things less bad, I decided to start writing these little docs. Here they are. I may add more. Or not. Whatevs.

Sometimes You Need to Build a Larger Thing First looks back at the road we've traveled.

Shadow DOM Evolution outlines the path forward.

Why Do We Only Allow Children in Insertion Points provides a glimpse into the reasoning behind current insertion point design.

List of JavaScript Crypto libraries.

JavaScript Crypto Libraries

List some crypto libraries for JavaScript out there. Might be a bit out dated. Scroll to the bottom.

WebCryptoAPI

http://www.w3.org/TR/WebCryptoAPI/

This specification describes a JavaScript API for performing basic cryptographic operations in web applications, such as hashing, signature generation and verification, and encryption and decryption. Additionally, it describes an API for applications to generate and/or manage the keying material necessary to perform these operations. Uses for this API range from user or service authentication, document or code signing, and the confidentiality and integrity of communications.

Fourier series visualisation with d3.js.

From Wikipedia:

In mathematics, a Fourier series decomposes periodic functions or periodic signals into the sum of a (possibly infinite) set of simple oscillating functions, namely sines and cosines (or complex exponentials).

Use the bottom right form to change the visualized serie.

MapBox Cloudless Atlas Tour

Speakers notes

Part of a presenation given at NACIS 2013: https://github.com/springmeyer/cloudless-nacis2013

  • Bahamas - land really pops due to blurred shallow nearshore
  • Australia - rich hues
  • Great Barrier Reef - Extremely subtle textures visible + water mask helps show smallest reefs
  • Amur River - effectively shows many combined flood events / murky water in delta
  • Taiwan - deforestation clearly visible
  • Tibet - Jewel lakes
