Instructions for exporting/importing (backup/restore) GPG keys

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/

ReStructuredText Youtube / Vimeo video embed directive
# -*- coding: utf-8 -*-
"""
ReST directive for embedding Youtube and Vimeo videos.
There are two directives added: ``youtube`` and ``vimeo``. The only
argument is the video id of the video to include.
Both directives have three optional arguments: ``height``, ``width``
and ``align``. Default height is 281 and default width is 500.

Mutt, Gmail and GPG

GPG / Mutt / Gmail

About

This is a collection of snippets, not a comprehensive guide. I suggest you start with Operational PGP.

Here is an incomplete list of things that are different from other approaches:

  • I don't use keyservers. Ever.
  • Yes, I use Gmail instead of some bespoke hipster freedom service

Installing STM32CubeMX on Linux

Installing STM32CubeMX on Linux

The STM32CubeMX tool is written in portable java, but unfortunately it is distributed as a Windows executable embedded in a Windows installer.

To install it on Linux:

  1. sudo java -jar SetupSTM32CubeMX-4.11.0.exe
  2. install the tool somewhere in your home, eg: /home/you/stm32/cubemx
  3. sudo chown -R you:you /home/you/stm32/cubemx
