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...

#! /usr/bin/env python
import fileinput
import argparse
from operator import itemgetter

parser = argparse.ArgumentParser()
parser.add_argument('--target-mb', action = 'store', dest = 'target_mb', default = 61000, type = int)
parser.add_argument('vmtouch_output_file', action = 'store', nargs = '+')
args = parser.parse_args()

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 = git@github.com: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:

# Enable noatime on local ext3/4 & xfs filesystems

fstab = File.open('/etc/fstab',"r")
newlines = Array.new
needremount = Array.new
ihaveswap = false
fstab.each do |line|
  # Tokenize each fstab line with a space separator
  tokens = line.split
  if tokens[2] == "swap"

Irssi in Mac OS X Notification Center

Overview

This guide will explain how you can make irc messages in a screen on a remote server appear in your Mac OS X Lion Notification Center with the help of terminal-notifier.

We will also explain how the process can be automatically started each time you log in to your Mac and ensure the connection to the server is kept alive.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

To comment a single line use

  <%-# commented line -%>

This also works

  <%# my comment %>

To comment a whole block use a if false to surrond your code like this

randerzander

USER='admin'
PASS='admin'
CLUSTER='dev'
HOST=$(hostname -f):8080

function start(){
  curl -u $USER:$PASS -i -H 'X-Requested-By: ambari' -X PUT -d \
    '{"RequestInfo": {"context" :"Start '"$1"' via REST"}, "Body": {"ServiceInfo": {"state": "STARTED"}}}' \
    http://$HOST/api/v1/clusters/$CLUSTER/services/$1
}
