So there were a few threads going around recently about a challenge to write the longest sequence of keywords in Javascript:

• https://twitter.com/bterlson/status/1093624668903268352
• https://news.ycombinator.com/item?id=19102367

There are, however, a few problems:

• These solutions use non-keyword tokens (null, true, false are actually Literals, not Keywords)
• One of the solutions isn't quite valid (new super)

/* bling.js */

window.$ = document.querySelectorAll.bind(document);

Node.prototype.on = window.on = function (name, fn) {
  this.addEventListener(name, fn);
};

NodeList.prototype.__proto__ = Array.prototype;

In-Application Sandboxing with Web Workers

A design rationale.

For the past fews years, the Web has been shifting control to the client. Given the limitations of remote services, developers are now looking for ways to "unhost" static applications – that is, break the dependency on remote servers while still using the Web platform.

One untapped technology for client-side control is the Web Worker Sandbox. This API lets the Page load, execute, and destroy separate Worker threads which use their own Virtual Machines. By using Worker Sandboxes to drive behavior, the Web can give users the choice of which software they run together, shifting development from a centralized SaaS model into a distributed and free (as in freedom) script-sharing model.

Worker Sandboxes can Execute Arbitrary Code

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

// requires underscore.js for `_.clone`, although come to think about it could be done without it.

// The router module.
var router = (function () {

  // Get the location array and filter out empty strings.
  var path = window.location.pathname.split('/').filter(Boolean)
      // The param arg stack.
    , arg_stack = [];

""" Convert values between RGB hex codes and xterm-256 color codes.

Nice long listing of all 256 colors and their codes. Useful for
developing console color themes, or even script output schemes.
