#!/bin/bash
# Utility script for making it easier to sign stuff for Keybase.io with an
# airgapped offline key.
#
# Usage:
# 1. Set the `REMOVABLE_DEVICE_UUID` below (see `$ lsblk -o +FSTYPE,UUID`)
# 2. Go to keybase.io and add a new key or proof, track someone etc.
# 3. Choose to sign manually
# 4. Copy the script to the Xorg primary clipboard (should be enough to just
# select it all - triple-clicking the text box does the trick in Firefox)

Last active March 31, 2016 08:38
#!/bin/bash
# Clean out Syncthing *.sync-conflict-* files from Password Store
#
# Usage: Run the script from anywhere with no parameters.
#
# The script will remove all conflict files in `~/.password-store` for which
# the plaintext contents of the original file and the conflict file have the
# same SHA256 checksum. I.e. if `foo.sync-conflict-20151115-205258.gpg` and
# `foo.gpg` have the same checksums after decrypting, then the former will be
# removed.

Shenzhen I/O: Frobnicator
-- The function get_name() should return a single string that is the name of the puzzle.

function get_name()
return "Frobnicator"
end
-- The function get_description() should return an array of strings, where each string is
-- a line of description for the puzzle. Surrounding text with asterisks will cause it to
-- be rendered in bold, something we use when mentioning a signal by name.
