Dan-Q / whitespace-a-like.rb
Created November 26, 2012 23:06
Encode a Ruby program into a version composed almost entirely of unicode whitespace characters. Decodes itself on the fly.
#!/usr/bin/env ruby
# encoding: utf-8
CHARS = %w{                       ​ ‌ ‍   　}
def encode(string)
string.chars.map{|c|"#{CHARS[c[0]/16]}#{CHARS[c[0]%16]}"}.join
end

Dan-Q / grimesweeper.rb
Created March 18, 2013 15:51
Calculates the probabilities of victory using unusual combinations of non-transitive dice. Does not make any optimisations (e.g. ruling out always-lose/always-win combinations on a DiceSet) at all, so it quickly slows down if, for example, two players each throw six dice.
#!/usr/bin/env ruby
# Grimesweeper
# Calculates the victory chances if different combinations of Grime Dice (non-transitive dice) against one another
# Inspired by https://protonsforbreakfast.wordpress.com/2013/01/08/amazing-dice-rediscovering-surprise/

Dan-Q / zen-hangman.rb
Created December 11, 2013 13:21
What's the hardest-to-guess word in Hangman, for any given number of letters? Give this program a wordlist.txt and a number of letters, and it'll tell you, by repeatedly playing an optimised game against itself and then sorting the results.
#!/usr/bin/env ruby
# -*- coding: iso-8859-1 -*-
# Inspired by http://datagenetics.com/blog/april12012/index.html
# Comes up with the "hardest words" to guess, in hangman, assuming the player is playing optimally
# (choosing the letter most-likely to appear, given a dictionary of all candidate words and the
# letters guessed so far [because hangman guesses are not independent; they affect the gamestate
# either by saying "this letter DOES NOT feature" or by saying "this letter features in THESE
# positions"])
# Result: a "hardest hangman words" dictionary?

Improved version of getButterly's teleprompter script, originally found at http://getbutterfly.com/jquery-tv-teleprompter-script/. This version does not require MySQL and needs no set-up before it works. It's still vulnerable to unescaped inputs damaging the settings.
<?php
if(isset($_POST['submit'])) {
$save_result = file_put_contents('settings.ini',
array("[prompter]", "\n",
"text_size=", $_POST['text_size'], "\n",
"text_colour=", $_POST['text_colour'], "\n",
"text_speed=", $_POST['text_speed'], "\n",
"container_height=", $_POST['container_height']));
if($save_result === false) die('Failed to save settings: check write permission on settings.ini.');

Dan-Q / extract-features.rb
Created April 22, 2015 09:17
A tool written during the EEBO-TCP Hackathon at the Weston Library, University of Oxford, in March 2015. Extracts markup features from XML documents and produces HTML tables showing their frequency across a corpus.
#!/usr/bin/env ruby
#
# Run in a directory containing any number of XML files from the EEBO-TCP project,
# which can be acquired via Github at https://github.com/textcreationpartnership,
# among other ways. It uses the Nokogiri XML parser to perform frequency counts of
# each of the selected features (specified in CSS3 syntax) and outputs the result
# to a HTML table (by default, called "output.html").
#
# Thrown together quickly for the EEBO-TCP Hackathon at the Weston Library in Oxford
# in March 2015, as described at https://danq.me/2015/04/22/eebo-tcp-hackathon, this

Dan-Q / split-message.rb
Created November 2, 2016 21:28
Ugly Ruby code to split a message into two messages with alternate words escaped.
msg = "Your message goes here."
[true, false].each{|x|puts msg.split(' ').map{|w|(x = !x) ? w : ('_'*w.length)}.join(' ')}
# Result:
# ____ message ____ here.
# Your _______ goes _____
