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...

First and foremost, let's take a look at the following pieces of code. The first one is something you should be rather familiar with, and the second one is also a somewhat familiar idiom these days (at least in languages with higher-order functions):

// Example 1:
30 + 12

// Example 2:
xs.map(f)

UFW

I use Ubuntu’s Uncomplicated firewall because it is available on Ubuntu and it's very simple.

Install UFW

if ufw is not installed by default be sure to install it first.

I was tired of Chrome eating all my laptop resources so I decided to put some limit to it with cgroup.

As I was using Ubuntu 12.04 with support for cgroup, I installed the package cgroup-bin and add the following group to the file /etc/cgconfig.conf:

group browsers {
    cpu {
#       Set the relative share of CPU resources equal to 25%
        cpu.shares = "256";
 }

	# This is a demonstration script for Facebook Chat
	# using the X-FACEBOOK-PLATFORM SASL mechanism.
	# It requires pyfacebook and pyxmpp to be installed.

	# This client only works for desktop applications (configured in the
	# developer app), and uses the old-style auth.getSession mechanism to get a
	# Facebook session. For newer-style or web apps, only the
	# `get_facebook_client` function should have to change.

	# bash generate random 32 character alphanumeric string (lowercase only)
	cat /dev/urandom \| tr -dc 'a-z0-9' \| fold -w 32 \| head -n 1
