Raise Open File Limits in OS X

in OS X 10.4 to macOS sierra 10.12 and maybe higher!

Create Launcher Script:

`/Library/LaunchDaemons/limit.maxfiles.plist`

Copy this entire code block and paste it into your terminal and push Return to create this file for you with correct permissions. It will (probably) ask for your password:

How to set up stress-free SSL on an OS X development machine

One of the best ways to reduce complexity (read: stress) in web development is to minimize the differences between your development and production environments. After being frustrated by attempts to unify the approach to SSL on my local machine and in production, I searched for a workflow that would make the protocol invisible to me between all environments.

Most workflows make the following compromises:

Use HTTPS in production but HTTP locally. This is annoying because it makes the environments inconsistent, and the protocol choices leak up into the stack. For example, your web application needs to understand the underlying protocol when using the secure flag for cookies. If you don't get this right, your HTTP development server won't be able to read the cookies it writes, or worse, your HTTPS production server could pass sensitive cookies over an insecure connection.
Use production SSL certificates locally. This is annoying

Update May 2017

Eric Bidelman has documented some of the common workflows possible with headless Chrome over in https://developers.google.com/web/updates/2017/04/headless-chrome.

Update

If you're looking at this in 2016 and beyond, I strongly recommend investigating real headless Chrome: https://chromium.googlesource.com/chromium/src/+/lkgr/headless/README.md

Windows and Mac users might find using Justin Ribeiro's Docker setup useful here while full support for these platforms is being worked out.

	$: (Dollar Colon) is basically a shorthand version of $LOAD_PATH.
	contains an array of paths that your script will search through when using require.
	$0 (Dollar Zero) contains the name of the ruby program being run. This is typically the script name.
	$* (Dollar Splat) is basically shorthand for ARGV. $* contains the command line arguments that were passed to the script.
	$? (Dollar Question Mark) returns the exit status of the last child process to finish.
	$$ (Dollar Dollar) returns the process number of the program currently being ran.
	$~ (Dollar Tilde) contains the MatchData from the previous successful pattern match.
	$1, $2, $3, $4 etc represent the content of the previous successful pattern match.
	$& (Dollar Ampersand) contains the matched string from the previous successful pattern match.
	$+ (Dollar Plus) contains the last match from the previous successful pattern match.

	# Mac OS X Lion introduced a new, iOS-like context menu when you press and hold a key
	# that enables you to choose a character from a menu of options. If you are on Lion
	# try it by pressing and holding down 'e' in any app that uses the default NSTextField
	# for input.
	#
	# It's a nice feature and continues the blending of Mac OS X and iOS features. However,
	# it's a nightmare to deal with in Sublime Text if you're running Vintage (Vim) mode,
	# as it means you cannot press and hold h/j/k/l to move through your file. You have
	# to repeatedly press the keys to navigate.
