Any recommendations on how to find community meetup groups (online and in person)? I'm specifically looking for tech stuff in SF. I know there should be so many groups for this, but I'm not sure where to start.

Thanks!

Any scifi recommendations? I'm specifically looking for works that do something interesting with fictional technology (which is the point of this genre, but I've seen a lot that just slap on aliens and call it a day). I have no preference for hard/soft and any medium is fine.
