The NYTimes has updated their paywall-- it's slightly more sophisticated. The content is no longer hidden behind a big transparent div, but instead is now actually removed from the page entirely. It's still simple to defeat, though. Using adblock plus (or your preferred adblocking device), block the following URLs:

*://*.nytimes.com/*/gwy.js*
*://*.nytimes.com/*/gw.js*

And you're done.

One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

Mathematics: What do grad students in math do all day?

by Yasha Berchenko-Kogan

A lot of math grad school is reading books and papers and trying to understand what's going on. The difficulty is that reading math is not like reading a mystery thriller, and it's not even like reading a history book or a New York Times article.

The main issue is that, by the time you get to the frontiers of math, the words to describe the concepts don't really exist yet. Communicating these ideas is a bit like trying to explain a vacuum cleaner to someone who has never seen one, except you're only allowed to use words that are four letters long or shorter.

What can you say?

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:

puffnfresh

function arityGuard(f) {
  function guarded() {
    var length = f._length || f.length;
    if(arguments.length != length) {
      throw new TypeError(
        (f._name || f.name || '<anonymous>') +
        ' called with ' +
        arguments.length +
        ' argument(s), expected ' +
        length

What this is

The Boulder Haskell Group is going to start working on a shared project to enhance the HSQML library on Hackage, which binds to the QT library for cross-platform GUI development.

This doc is a braindump currently. Please send pull requests w/ any more found out information as we go. It will probably be edited down and become a real README at somepoint for our new project.

This is material to go along with a 2014 Boston Haskell talk.

We are going to look at a series of type signatures in Haskell and explore how parametricity (or lack thereof) lets us constrain what a function is allowed to do.

Let's start with a decidedly non-generic function signature. What are the possible implementations of this function which typecheck?
