[Haskell-cafe] is it normal for docs to be pending for 24 hours?

I didn't realise that. Let me read more about the problems that stack is
trying to solve vs those that cabal is trying to solve. To my untrained
eye, they're solving very similar problems to exist as two separate
projects. Isn't a package a kind of a project? Or vice-versa.

As I said, I need to read more on this topic.

Was the only reason to suggest the fetching of curated lists from Stackage
in interest of faster go-to-market? Wouldn't it require the community to
maintain 2 sets of highly-available infra? Also, wondering aloud, is the
curation process purely algorithmic or human assisted?

Where can I read more about GPS Haskell? I managed to get to
http://www.ozonehouse.com/mark/platform/GPS-Haskell-HIW2014.pdf from your
blog post at https://www.fpcomplete.com/blog/2014/12/backporting-bug-fixes,
but it's a 404 right now.
