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.
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...
I came across 'bundler/inline' in Bundler pull request 3440, which I'd found from Rails pull request 20429. This now has a little snippet on the What's new page of the Bundler site.
This little example demonstrates how I might use it to create a single file using minitest.
I've just noticed that this script was working for me because I already had minitest installed as a system gem. If I uninstall the gem then the script fails because it can't find minitest. The source code documents an option to install gems if they don't exist (gemfile(true) do) but that doesn't seem to work for me. I see the following error:
Fetching gem metadata from https://rubygems.org/...
Fetching version metadata from https://rubygems.org/..

I added two verified email addresses to AWS SES so that I could send emails from/to them while in the SES Sandbox.

I receive a number of periodic emails that prompt me to do something (e.g. take an electricity meter reading). I wanted to be able to add information to those emails to remind me how to perform the task.
This JavaScript allows me to configure rules so that I can display a link to a web page when I'm viewing an email with a specific subject in Gmail.
I'm currently hosting the JavaScript and installer web page using rawgit.com.

The todoist.rb script uses their API to print a list of all my completed tasks in CSV format.
The standard Todoist backup doesn't contain completed tasks.
It looks as though using Release Phase commands (available as of 2 June 2016) is the preferred way of running things like migrations after the slug has been compiled and deployed.
The Buildpack API explicitly suggests avoiding side effects during the build:
Buildpack developers should avoid generating side effects during the build. For example, it is not recommended to perform database migrations in the compile script.
The following example creates a Rails app with a single migration and demonstrates that the migration is run after deployment.
