Sam Ruby's "long bets" don't seem so far off considering how quickly changes are happening on the internets....
By the way, have you seen the erlang "slave" and "pool" libraries? These might not do entirely what you want. Good news: applicable as-is. Even better: they can be (re-)implemented in not-so-much erlang to do entirely what you want.
So, without further ado, here’s my long bets for the moment, with the only caveat that in some cases I pick specific implementations as exemplars of a larger field.
Maybe its time really has come.
