John Hoot presented at the 2018 SAS meeting a talk: A Linux Virtual Machine for Astronomy and Education where he describes a collection of tools for astronomers that he is making available. You can get it via mail following the instructions at his website.
I was wondering if anyone knows of a place to download it; nowadays a 32Gb download is not too daunting.
If not I'll get a copy and make it available on request.
Cheers,
George
