Considering how the user benefits when a mature project goes fully open-sourceāeven one with the baggage of something like Gumroad.
I stumbled upon this nice little program to keep an eye on your system files to make sure no one inappropriate is changing them! I like to have this run in cron once a week and send me a report. When your first changing your system / installing things, a lot of false positives will be tripped. But, once you settle into your system and are not constantly installing things and changing config files ā this can be a handy service to have running to keep an key on your filesystem.
