Nginx: stat() failed (13: permission denied)

from https://stackoverflow.com/questions/25774999/nginx-stat-failed-13-permission-denied

Nginx operates within the directory, so if you can't cd to that directory from the nginx user then it will fail (as does the stat command in your log). Make sure the www-user can cd all the way to the /username/test/static. You can confirm that the stat will fail or succeed by running

sudo -u www-data stat /username/test/static

The difference is that for builds a lazy sequence and returns it while doseq is for executing side-effects and returns nil.

user=> (for [x [1 2 3]] (+ x 5)) (6 7 8) user=> (doseq [x [1 2 3]] (+ x 5)) nil user=> (doseq [x [1 2 3]] (println x)) 1
