# 30 minutes Lisp in Ruby
# Hong Minhee <http://dahlia.kr/>
#
# This Lisp implementation does not provide a s-expression reader.
# Instead, it uses Ruby syntax like following code:
#
#     [:def, :factorial,
#       [:lambda, [:n],
#         [:if, [:"=", :n, 1],
#               1,

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...

Let's say you have an iOS project, and you want to use some external library, like AFNetworking. How do you integrate it?

With submodules

Add the project to your repo:

git submodule add git@github.com:AFNetworking/AFNetworking.git Vendor/AFNetworking

or something to that effect.

# Usage: Add it to your PATH and `git remove-submodule path/to/submodule`.
#
# Does the inverse of `git submodule add`:
#  1) `deinit` the submodule
#  2) Remove the submodule from the index and working directory
