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...

Download and install p4merge

Download the perforce visual tool suite from here: http://www.perforce.com/perforce/downloads/index.html
Copy only the p4merge.app file into your /Applications/ directory

Setup p4merge as a visual mergetool

I just had to set up Jenkins to use GitHub. My notes (to myself, mostly):

Detailed Instructions

For setting up Jenkins to build GitHub projects. This assumes some ability to manage Jenkins, use the command line, set up a utility LDAP account, etc. Please share or improve this Gist as needed.

Install Jenkins Plugins

get both the git and github plugin

Atom Clojure Setup

This describes how I setup Atom for an ideal Clojure development workflow. This fixes indentation on newlines, handles parentheses, etc. The keybinding settings for enter (in keymap.cson) are important to get proper newlines with indentation at the right level. There are other helpers in init.coffee and keymap.cson that are useful for cutting, copying, pasting, deleting, and indenting Lisp expressions.

The Atom documentation is excellent. It's highly worth reading the flight manual.
