Thanks for the request. Both Emacs and Latex are definitely worth learning. Emacs is a very efficient text editor and Latex allows you to focus only on your writing and then have it typeset into beautiful documents with all sorts of math notation.
Unfortunately, however, I’ve never really used Emacs. I’m more of a Vim guy. So if I write an article, it would probably be on Vim, not Emacs. But I can’t promise anything anytime soon. I still got a long list of other topics I want to write about first. But I’ll definitely take note!
