Autofs on Mac OS X

With autofs you can easily mount network volumes upon first access to the folder where you want to mount the volume. Autofs is available for many OS and is preinstalled on Mac OS X so I show you how I mounted my iTunes library folder using this method.

Prepare autofs to use a separate configuration file

autofs needs to be configured so that it knows where to gets its configuration. Edit the file /etc/auto_master and add the last line:

#
# Automounter master map
#

+auto_master # Use directory service

$Path = 'i:\'
$OutCSV = 'c:\Windows\Temp\i_drive_suspects.csv'
$RegEx = "[^-\w\.\ \~\'\(\)\$\&\+\,\@\%]" # This matches anything that isn't a-z, A-Z, 0-9, or the '-', '_', and '.' characters.  Add any others you need to permit.

$Output = Get-ChildItem -Path $Path -Recurse | Where-Object -FilterScript { $_.Name -match $RegEx } | ForEach-Object {

true and false vs. "truthy" and "falsey" (or "falsy") in Ruby, Python, and JavaScript

Many programming languages, including Ruby, have native boolean (true and false) data types. In Ruby they're called true and false. In Python, for example, they're written as True and False. But oftentimes we want to use a non-boolean value (integers, strings, arrays, etc.) in a boolean context (if statement, &&, ||, etc.).

This outlines how this works in Ruby, with some basic examples from Python and JavaScript, too. The idea is much more general than any of these specific languages, though. It's really a question of how the people designing a programming language wants booleans and conditionals to work.
