i asking question because, while have found related topics, of focus on using dropbox remote, haven't found addresses question: is there hazardous using dropbox local repo way work seamlessly from/between multiple machines (eg. let's made fork, make changes on desktop, want continue work laptop without running $ git commands), having remote elsewhere? another way ask question might be: there way use of dropbox-connected machines 1 local development space ... idea of machines on dropbox 1 machine purposes of development... know isn't clear way ask question, don't know how can more clear. i want make sure there won't conflicts between how repository tracks changes, , way synced via dropbox - more particularly, wondering if make commit, or stage file(s) on machine (let's call these "operations"), , update dropbox-syncs machine b, operations reflected on machine b when dropbox-sync complete, git run automatically ensure operations ref...

here's tree of boolean predicates. data pred = leaf (a -> bool) | , (pred a) (pred a) | or (pred a) (pred a) | not (pred a) eval :: pred -> -> bool eval (leaf f) = f eval (l `and` r) = \x -> eval l x && eval r x eval (l `or` r) = \x -> eval l x || eval r x eval (not p) = not . eval p this implementation simple, problem predicates of different types don't compose. toy example blogging system: data user = u { isactive :: bool } data post = p { ispublic :: bool } userisactive :: pred user userisactive = leaf isactive postispublic :: pred post postispublic = leaf ispublic -- doesn't compile because , requires predicates on same type -- usercancomment = userisactive `and` postispublic you around defining data world = w user post , , exclusively using pred world . however, adding new entity system necessitates changing world ; , smaller predicates don't require whole thing ( postispublic doesn...
