How To: Enable TRIM with Non-Apple SSD

The guide breaks the process down into three steps, all performed via copying and pasting the code snippets through the terminal window. To launch a terminal window, open the Utilities folder inside the Applications folder and select terminal.

The first step makes a backup of the original IOAHCIBlockStorage file called IOAHCIBlockStorage.original. You will be prompted to enter in your system password when using the "sudo" command, since you are modifying system files. Copy and paste the code into the terminal window, a successful or uneventful response is a new blank terminal line.

sudo cp /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage.original

Next the code patches the IOAHCIBlockStorage file, removing the requirements that the SSD be made by Apple. Copy and paste t

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

	// Usage:
	// p(instance)('privateMethod)(arg1, arg2, arg3)

	class PrivateMethodCaller(x: AnyRef, methodName: String) {
	def apply(_args: Any*): Any = {
	val args = _args.map(_.asInstanceOf[AnyRef])
	def _parents: Stream[Class[_]] = Stream(x.getClass) #::: _parents.map(_.getSuperclass)
	val parents = _parents.takeWhile(_ != null).toList
	val methods = parents.flatMap(_.getDeclaredMethods)
	val method = methods.find(_.getName == methodName).getOrElse(throw new IllegalArgumentException("Method " + methodName + " not found"))

	#!/usr/bin/env ruby
	# Usage: gitio URL [CODE]
	#
	# Turns a github.com URL
	# into a git.io URL
	#
	# Copies the git.io URL to your clipboard.

	url = ARGV[0]
	code = ARGV[1]

	class Filters[T] {

	//Some boilerplate-busting aliases
	type FilterResult = Either[Rejection, T]
	type FilterFunc = (T) => FilterResult

	//Handy helpers
	//Rejection can carry as much info as you wish;
	// Filter name, value in error, an exception, etc.
	case class Rejection(input: T, msg: String)
