For anyone who doesn't know, today is the day for EmacsConf 2019. As you might gather from the name, it's a conference all about Emacs, the joys of Emacs, Emacs Lisp and other Emacs-related things.
Better still, it's an online conference (although there do appear to be a couple of related physical gatherings around the world).
I've got snacks and drinks in and no plans for my Saturday, and I hope to follow the whole thing from start to finish.
If Emacs is your thing, or knowing more about Emacs is your thing, be sure to check it out!
