About Fun With GenServers

GenServers are fun! Andreas gives all the context. Things were learned, knowledge was aquired. You can do so much with GenServers, but make sure you have a good reason.

If you don't watch out, this is where concurrency goes to die.

Dynamic supervisors, and their children, are thoroughly considered.

Also delved into is the mess other ecosystems make of doing things at the same time, waiting, and so on.

The strange worlds of C and other unusual languages are considered.

Finally, an interesting bug.
