I'm a mathematician at UNAM in Mexico City. I work in algebraic topology, homotopy theory and higher category theory, but am interested in all sorts of math.
I also enjoy computer programming as a hobby and am a big fan of the text editor Emacs.
A master's student of mine wanted to go to a workshop in Canada and applied for a visa. He was rejected for reasons that sound insane to me: they said he didn't have sufficient family ties outside of Canada (his entire family lives in Mexico!); and they said it wasn't clear that he would benefit from attending the workshop (which I consider to be an academic decision that this embassy employee was not equipped to make!).
I've seen many, many students be rejected for American visas, but I think this is the first time I've seen this happen with a Canadian visa.
@jameshowell@fediscience.org How is this different from using Emacs's built-in backup system¹ configuring backup-enable-predicate to check for membership in your list of precious files (and configuring backup-directory-alist to put the backups wherever you want them)?
