Duplicates in Views with random sort
So to make sure everyone gets a fair shot in the building of ARTLIB I've used (Global) Random sort on various Views based search results.
Trouble is (as some smart cookie pointed out) across paginated pages we see duplication. This is because the random seed in Views is generated every page load. Thats not good.
Of course this is a common problem so there is a common solution. Views Random Seed. This is a drop-in replacement for the builtin (Global) Random sort with a couple of options. You can vary the expiry time and share the randomness across all users of the site (ensuring that everyone sees the same random at the same time). Nice! Thanks swentel!
