Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

Install ImageMagick for image conversion:

brew install imagemagick

Install tesseract for OCR:

brew install tesseract --all-languages

Or install without --all-languages and install them manually as needed.

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

	// this return the url that redirects to the according user image/avatar/profile picture
	// implemented services: google profiles, facebook, gravatar, twitter, tumblr, default fallback
	// for google use get_avatar_from_service('google', profile-name or user-id , size-in-px )
	// for facebook use get_avatar_from_service('facebook', vanity url or user-id , size-in-px or size-as-word )
	// for gravatar use get_avatar_from_service('gravatar', md5 hash email@adress, size-in-px )
	// for twitter use get_avatar_from_service('twitter', username, size-in-px or size-as-word )
	// for tumblr use get_avatar_from_service('tumblr', blog-url, size-in-px )
	// everything else will go to the fallback
	// google and gravatar scale the avatar to any site, others will guided to the next best version

	### Locating UI elements ###

	# By ID
	<div id="coolestWidgetEvah">...</div>
	element = driver.find_element_by_id("coolestWidgetEvah")
	or
	from selenium.webdriver.common.by import By
	element = driver.find_element(by=By.ID, value="coolestWidgetEvah")

	# By class name:

	SELECT
	-- Assumed to be trimmed
	name

	-- Does name contain multiple words?
	,(LOCATE(' ', name) = 0) AS hasMultipleWords

	-- Returns the end of the string back until reaches a space.
	-- E.g. "John Doe" => "Doe"
	-- E.g. "Francis Scott Key" => "Key"
