GNU Parallel's intro videos are available on Youtube. But I have long been dissatisfied with Youtube's surveillance and arbitrary private censorship.
So I have been looking for an alternative, that was: * distributed (so no single organization can shut it down or censor it) * free software (so if the organization behind turns evil, we can fork the code) * and easy to run for normal people (if you need to port forward or have a 24/7 server, my mum cannot join the party) I think I have found it. It is called LBRY and you can get the software here: https://lbry.com/get LBRY is sort of a mix between Youtube, Bittorrent and Patreon; and I will highly encourage you to test it - especially if you are critical of Youtube's influence. You find GNU Parallel's channel at lbry://@GnuParallel:4 (or if you still have not installed the desktop program: https://odysee.com/@GnuParallel:4). And you can even download the latest version of GNU Parallel through LBRY at lbry://@GnuParallel#4/parallel-20210422.tar.bz2#b /Ole
