- 1. We ♥ Haskell ------------------ by @heidiHarman & @greenEmilyMay @scrive Monday, August 15, 2011
- 2. We ♥ Haskell ------------------ The story behind SkrivaPå and more about Haskell Monday, August 15, 2011
- 3. @heidiHarman & @greenEmilyMay @scrive @skrivaPa @scrive_UK Emily Green Heidi Harman :: JavaDev -> HaskellDev -> _ Kaospilot, Denmark ServerCode _ Planner, projectmanager = :: BristolUni -> Maths -> Degree webagencies :: JQuery -> CSS -> GUICode _ IFL Stockholm School of Economics :: Bank -> Scrive -> Happy _ Agencies _ Runalong Startup _ GeekGirlMeetup _ London, Scrive Monday, August 15, 2011
- 4. Structure allows freedom Monday, August 15, 2011
- 5. Or as Björk would have put it: “I tried organizing freedom, how scandinavian of me” Monday, August 15, 2011
- 6. SkrivaPå aka Scrive Digital signatures for contracts etc Monday, August 15, 2011
- 7. @heidiHarman & @greenEmilyMay @scrive @skrivaPa @scrive_UK Why SkrivaPå? > Proven business model and product > A fantastic Team Monday, August 15, 2011
- 8. @heidiHarman & @greenEmilyMay @scrive @skrivaPa @scrive_UK Why SkrivaPå? Yes, it’s as simple as that! > Proven business model and product > A fantastic Team Monday, August 15, 2011
- 9. @heidiHarman & @greenEmilyMay @scrive @skrivaPa @scrive_UK Tibetan Patches 3 3 3 1 Monday, August 15, 2011
- 10. @heidiHarman & @greenEmilyMay @scrive @skrivaPa @scrive_UK We Use Haskell Because the CTO, Gracjan, wanted to. “Haskell, whatʼs that?” > Itʼs a strongly typed, lazily evaluated, functional language. “Haskell, thatʼs a brave choice.” > Itʼs well-known and loved in academic circles, but a bit unusual of an unusual choice for building “real stuff”. Monday, August 15, 2011
- 11. @heidiHarman & @greenEmilyMay @scrive @skrivaPa @scrive_UK Can I Describe What itʼs Like? Imagine: Variables canʼt change value. Once you set the value of a variable you canʼt change it. Ever. (If you ask me how to keep an incrementing count of user logins, I shall say “monads”.) Monday, August 15, 2011
- 12. @heidiHarman & @greenEmilyMay @scrive @skrivaPa @scrive_UK Functions Only :: Input -> AnotherInput -> Output Want to go mess around with something that isnʼt stated in the type signature. Hard cheese. You canʼt. Monday, August 15, 2011
- 13. @heidiHarman & @greenEmilyMay @scrive @skrivaPa @scrive_UK My, this sounds insane, why?! Answer: some things are easier The thing thatʼs making functional languages like Haskell popular at the moment is ........ Programming for Multiple Cores Monday, August 15, 2011
- 14. @heidiHarman & @greenEmilyMay @scrive @skrivaPa @scrive_UK How many cores does your computer have? How many will it have in 3 years time? Monday, August 15, 2011
- 15. @heidiHarman & @greenEmilyMay @scrive @skrivaPa @scrive_UK Immutability Makes Multi- Threaded Code Easier Did you know Twitter uses a functional language for itʼs highly threaded server code? Monday, August 15, 2011
- 16. @heidiHarman & @greenEmilyMay @scrive @skrivaPa @scrive_UK TypeSafe saveAddress :: String -> Maybe Error User newtype Email = String saveAddress :: Email -> Maybe Error User Monday, August 15, 2011
- 17. @heidiHarman & @greenEmilyMay @scrive @skrivaPa @scrive_UK Structure Gives Freedom But it makes compilation longer > “Like a logician on your shoulder” - eric > GHC magic Monday, August 15, 2011
- 18. @heidiHarman & @greenEmilyMay @scrive @skrivaPa @scrive_UK Itʼs Different > Do you miss that excited feeling you got when you coded as a kid. Become a happy idiot again, learn Haskell. Monday, August 15, 2011
- 19. @heidiHarman & @greenEmilyMay @scrive @skrivaPa @scrive_UK Quest to Grok the Monad > If you learn Haskell you will quickly hear the word “monad”. Keep calm. Monday, August 15, 2011
- 20. @heidiHarman & @greenEmilyMay @scrive @skrivaPa @scrive_UK I love one thing more than Haskell, Haskell coders. Tip: if someone learns Haskell just to work on your project, theyʼll probably do a good job. Monday, August 15, 2011
- 21. Thank you Monday, August 15, 2011
