#!/usr/bin/env sh
# shellcheck disable=SC2214
#
# A POSIX-compliant shell script that estimates the number of hours taken to
# create the contents of a Git repository. The heuristic is based on grouping
# bundles of commits according to a certain period limit, accumulating time
# differences between pairs of commits in each bundle, and compensating for its
# first commit with another parametrized quantity. Timestamps are taken from
# the author of the commit.

#!/usr/bin/env bash
# shellcheck disable=SC2214
#
# A shell script that shows the size of a file in each commit that modifies it,
# alongside the timestamp taken from the author of the commit. This is useful
# to visualize the size evolution of a file.
#
# It accepts a single option to customize its behavior, described as
# follows. The last argument must be a valid file tracked by its respective
# repository, with the first file obtained from git-ls-files(1) as default.

#!/usr/bin/env awk -f
#
# AWK script to send multiple `sendkey` commands to a QEMU virtual machine.
# It writes at a rate of roughly 40 keys per second, due to lower delays
# resulting in garbage output.
#
# It makes use of a TCP client created by an external utility, such as OpenBSD
# Netcat, to interact with QEMU's monitor and send a stream of `sendkey`
# commands. This is a practical way to transfer a small file or to script
# interactions with a terminal user interface.

Script that reconstructs the order of unlocked secrets in the `so.sol`
auxiliary save game file for The Binding of Isaac (2011 roguelite game).

The main save file for Isaac is called `serial.txt`, located inside the game
folder. It is the only file backed up by Steam Cloud [1], and its secrets field
does not hold the order in which these were unlocked. If the secondary file
`so.sol` is missing, it will be recreated without this information.

The idea is to use Steam achievement timestamps to recreate the unlocking order
of Isaac secrets. If a secret has no corresponding achievements, it is randomly
