Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

Results

Voronoi Tesselation

10000 pixels partitions in to 30 regions as follows:

415,  91, 596, 420, 347, 239, 313, 298, 447, 259, 
414, 229, 137, 347, 353, 449, 744, 453, 479, 313, 
362, 363, 494,  87, 343, 395, 327, 140,  62, 285

PSA :

just use GHC for OSX https://ghcformacosx.github.io

TLDR version, if you have homebrew

xcode-select --install ; brew tap homebrew/versions ;   brew tap homebrew/dupes \

Haskell vs Clojure

The JSON data is in the following format

{
    "Genesis": {
        "1": {
            "1": "In the beginning..." ,
            "2": "..."

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

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:

This choropleth encodes unemployment rates from 2008 with a quantize scale ranging from 0 to 15%. A threshold scale is a useful alternative for coloring arbitrary ranges.

This is a modification of Mike Bostock's example, so single out individual states, picked out using their FIPS code. The State outlines can be also be found on GitHubt @ https://gist.github.com/4090846. A Bottle sever is included, for viewing at home.
