A simple, drop-in replacement for ForEach-Object that automatically gathers up objects from the input pipeline and presents a progress bar as each item is processed by subsequent pipeline commands. Flexible options for presenting progress messages along with the progress bar.

	# Displays a progress bar as each computer is queried for
	# the state of its hard drives using WMI.
	# The Status parameter selects the computer name to display
	# in the progress message.

	' BY JOSH EINSTEIN
	'
	' This is an Excel VBA macro that transposes a contiguous range of selected cells in Excel
	' and repeats the header rows. Created specifically for a friend of mine, so probably not
	' generally useful.

	' To use, select a rectangular range of cells containing the table that you want to transpose.
	' The first row should include the header values across that you want to be repeated

Handle back button issues with Twitter Bootstrap's tab component.

	// Handle back button issues with Twitter Bootstrap's tab component.
	// Based on: http://stackoverflow.com/a/10120221/81769
	// It has been changed to avoid the following side effects:
	// - Switching tabs was being added to navigation history which is undesirable
	// (Worked around this by using location.replace instead of setting the hash property)
	// - Browser scroll position was lost due to fragment navigation
	// (Worked around this by converting #id values to #!id values before navigating.)
	$(document).ready(function () {

	if (location.hash.substr(0,2) == "#!") {

A PowerShell implementation of my Wolfram Alpha API search script. Unlike the Bash version, this one doesn't use XSLT to produce the output so it's easier to read.

Simple Wolfram Alpha queries from the Mac terminal. The XML parsing is incredibly basic (it just looks complicated because of the work needed to indent the lines to make it look good) so I haven't really tested it with any other results yet.

	url="http://api.wolframalpha.com/v2/query"
	appid="YOUR APP ID" # get one at https://developer.wolframalpha.com/portal/apisignup.html
	query="$@"
	value="$(perl -MURI::Escape -e 'print uri_escape($ARGV[0]);' "$query")"

	echo "Computing: $query"

	curl -s -L -G -d "input=$value&appid=$appid&format=plaintext" $url >/tmp/wolfram-alpha.xml

	xsltproc ~/Scripts/wolf.xslt /tmp/wolfram-alpha.xml

A CodePen by Josh Einstein. Keyboard Navigation in Table Cells - Uses jQuery to enable arrow key functionality in tables. Pressing up/down/left/right in input fields will move focus to adjacent cells. Doesn't currently deal with column spans or custom input scenarios such as on-the-fly input fields.

	<table id="people">
	<thead>
	<th>First Name</th>
	<th>Last Name</th>
	<th>Phone Number</th>
	<th>Location</th>

josheinstein / New-PSObject.ps1

I wish PowerShell object literals worked like this...

	# PowerShell 3 adds the new [PSCustomObject] pseudo type attribute which
	# lets you declare an object literal using a syntax very similar to that
	# of an ordinary Hashtable. (There's also a new [Ordered] attribute that
	# creates a hash table with the order of keys preserved.)
	#
	# But it only lets you declare an object literal with NoteProperties.
	# What I would really love to have seen is the syntax look for script
	# blocks and create ScriptProperties out of them if there is no param
	# block or ScriptMethods out of them if there is a param block.
