Salutations!

Salutations fellow Linux enthusiasts, users and newbies. I am a former astronomer, reborn data scientist, and have been using Linux actively over 20 years, although my first experimentation happened about 30 years ago. Despite of all that, I am not a guru (like a couple of my friends), so I do need to improve my Linux skills and know-how. That is one reason why I am here. The other is that once my Linux expertise expands, I would like to give back to the community and help those struggling with some mysterious problem.
