A backup of the jargon file
This has been immensely useful for me, personally, so I have downloaded the latest version (as of the time of this file's last commit) to hang onto in a publically available repo.
Other repos exist that do something very similar, but I'd also like my own in the event that I want to plug it in or link it to a future blog project. I throw around the jargon a lot ;)
There's a script, update.sh, that can be used to update the backup. If you're on Windows, you will need GOW or Cygwin, or Git Bash to run this. I recommend Git Bash, and running it in Git Bash.
