I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).

Data, Narratives and Uncertainty

Ideas for 2014

December has been a contemplative month, and January is going to be hectic.

I don't believe in setting goals or making resolutions for the New Year. Usually I just let the New Year pass by. But there are ideas circulating in my head that I know I want to spend more time figuring out in 2014 — these ideas are half-baked but I don't want to forget them.

One idea I'm grappling with is the relationship between data and narrative and how to communicate uncertainty.

	git checkout better_branch
	git merge --strategy=ours master # keep the content of this branch, but record a merge
	git checkout master
	git merge better_branch # fast-forward master up to the merge


	----------------------

	If you want your history to be a little clearer, I'd recommend adding some information to the merge commit message to make it clear what you've done. Change the second line to:

	$(document).ready(function() {
	$('body').on('click', '.set-to-now', function(e) {
	e.preventDefault();
	var target_selector = $(this).attr('data-target');
	var year = $(target_selector+'_1i');
	var month = $(target_selector+'_2i');
	var day = $(target_selector+'_3i');
	var hour = $(target_selector+'_4i');
	var minute = $(target_selector+'_5i');
	// var current = [year, month, day, hour, minute].map(function(item) {

	// Looks an element up by CSS selector and keeps it centered in the viewport on window resize
	// Useful for testing responsive versions of specific DOM elements


	// if jquery isn't loaded on the page, paste this code into the console first to load it:
	var jqURL = 'http://code.jquery.com/jquery-latest.min.js';
	var jqscript = document.createElement('script');
	jqscript.type= 'text/javascript';
	jqscript.src = jqURL;
	document.head.appendChild(jqscript);

	# These are shell functions to quickly create pansharpened RGB images ready for color correction
	# from a set of raw Landsat 8 TIF files in a given directory.

	# For example:
	# l8_pansharp LC81690352014169LGN00
	# Creates:
	# LC81690352014169LGN00_rgb_pansharp.tif

	# l8_rush_pansharp downloads a L8 tile from Google Storage (if they have it), extracts the relevant bands, then creates the pansharpened output.

	# This is a shell function to quickly grab the data for a given Landsat 8 tile ID from Google's servers
	# For example:
	# l8get LC81690352014169LGN00

	# The echo at the end is to remind myself of the syntax for extracting bands 8, 4, 3, and 2. (Pansharp, Red, Green, Blue)

	# On OSX this would go into your ~/.bash_profile file.
	# Requires gsutil from https://developers.google.com/storage/docs/gsutil_install
	# Most useful in conjunction with USGS' Earth Explorer: http://earthexplorer.usgs.gov/

	#! /bin/bash

	# Convert Landsat 8 GeoTIFF images into RGB pan-sharpened JPEGs.
	#
	# Requirements:
	# * gdal http://www.mapbox.com/tilemill/docs/guides/gdal/
	# * convert (image-magick)
