Edit 8/19: You might notice, the cover is no longer a jellyfish. While I know this is a slight disapointment for some - including myself - trust me when I say I have a plan to remedy this. Stay tuned! 

So as it turns out my petition for a kickass cover was ultimately unsuccessful. But the good news is that I’m not suck with something neither cute nor cuddly. Instead I got a Jellyfish, after spending some time thinking about it is pretty good. (Though certainly not as awesome as a hydra.)

Jellyfish Facts

  • Jellyfish can be found in every ocean. Therefore, in the time if trouble they can call on the nine pirate lords for help. Much like F# being able to use nine different programming paradigms and styles:
    • functional, imperative, object-oriented, metaprogramming, scripting, concurrent, reactive, declaritive, and awesome. (Yes, ‘awesome’ is a programming paradigm… and Haskell doesn’t support it.)
  • Jellyfish do not have a brain or central nervous system. Just like F#… umm… you don’t need a nervous system to write world-class applications?  Let me get back to you on this one…
  • The real reason I’m excited about having a Jellyfish on the cover is that they can Sting and Kill you. Like F#, Jellyfish are deadly.

So anyways, this October be on the lookout for Jellyfish Book!
