  • Really interesting Marcel, thanks​!​

    I think that you would be really interested in some of the most cutting-edge research that I have come across explaining crowds, open innovation, and citizen science.​

    • The amazon success factors !21
    • !22 How about applying the very same principles to software development?
    • So, instead of using the web browser… !23
    • …we connect our IDEs: !24 project

    • Crowdsourcing inside the IDE !25 ❷ Mine data,
 extract patterns
 create recommendation models Knowledge base ❸ Deliver mined
 knowledge to developers ❶ You sharing information Software Development gets social again!

    • A simple observation !55 You wouldn‘t expect a call to #dispose()
 in #createSomething(), right?
    • What you expect is... !56
    • How many words do you have for ‟create” ? !57

    • Let‘s back up here for a second! !61
    • We get (almost) language agnostic! !62
    • But all that only happens if you share… !63
    • !64 Yes, there is a duck somewhere.
