Updating expired GPG keys and their backup 🔑🔐💻

I use a GPG key to sign my git commits.

An error like this one might be a sign of an expired GPG key.

error: gpg failed to sign the data fatal: failed to write commit object

Macro Must-Haves

These are my must-have macros for running games online. I make full use of the compendium, which gives these macros access to common actions and rolls, saving me time.

Remember to add /w gm or @{selected|wtype} to hide sensitive info from your players. WTYPE is an attribute used in the 5th Edition OGL character sheet, a prerequisite for most of these.

Here's what my bar looks like.

Freeing up extra disk space inside a Docker container

Sometimes while running a command inside of a docker container, the container itself will run out of disk space and things can fail (sometimes in strange ways). This is not a guide on how to allocate resources, but a quick cookbook on how to free up disk space inside a container. See below for links to more resources and reading.

If at all possible, just run Docker with increased disk space

See Limit disk size and bandwidth of a Docker container.

# In order for gpg to find gpg-agent, gpg-agent must be running, and there must be an env
# variable pointing GPG to the gpg-agent socket. This little script, which must be sourced
# in your shell's init script (ie, .bash_profile, .zshrc, whatever), will either start
# gpg-agent or set up the GPG_AGENT_INFO variable if it's already running.

# Add the following to your shell init to set up gpg-agent automatically for every shell
if [ -f ~/.gnupg/.gpg-agent-info ] && [ -n "$(pgrep gpg-agent)" ]; then
    source ~/.gnupg/.gpg-agent-info
    export GPG_AGENT_INFO
