Mikalai Birukou will tell us about the third leg of his journey in building out web infrastructure at scale. He writes:

I have talked about Docker and LXC out of my own experience. Now I've been Salt-ing the whole infrastructure ( https://docs.saltstack.com/en/latest/ ).

I'd love to share my own finite experience, findings, choices (not ideal, of course). I'd love to hear your comments, your perspective and your "war stories".

As usual, I'll talk from a perspective of doing it from ground up, the simple way possible (forever novice).

 

John Eddie Kerr will deliver his long-anticipated presentation on LaTeX at his law library. He writes:

Not just for math and science, LaTeX has found its way into the law library I manage. I will demonstrate some of the documents I create in the library. I will also show what Gaelic and LaTeX have in common.

This will be a beginner-friendly presentation.
