  22. Mutual Assessment developer at center • developers: find driven people

    – potential collaborators • recruiters: identify fast learners aware of assessment • developers manage their “personal brands” everyone looking for passion 14
  23. Passion technology & learning • constantly searching for interesting new

    frameworks, languages enjoying others • motivated by appreciation, recognition, competition 15

    frameworks, languages enjoying others • motivated by appreciation, recognition, competition 15 “This incredible group of fascinating people that get interested in all sorts of things, makes it interesting to talk with them, and work with them.”
  25. Passion inspiration • new technologies • best practices • development

    culture 16

    culture 16 “On Twitter, I follow a few prominent software developers. For example, Kelly Sommers from Canada, she’s constantly trying new things. I don’t think she ever sleeps. She’s a great source of inspiration.”
  27. Coder Footprint technical niche • relevant? standing in community •

    important? interesting? 17
  28. Coder Footprint technical niche • relevant? standing in community •

    important? interesting? 17 “When I look at repos around this topic, I may be interested in seeing the coder footprint of people that work in this area: their favorite languages, the topics they write code about, what they work on”
  29. Diversity … technologies • everything with single framework or tries

  31. Developer Profile Aggregators first step at aggregated coder footprint •

    superficial non-technical recruiters struggled • unsure: what do achievements mean? • misintepretations 19
  32. Developer Profile Aggregators developers / technical recruiters • first overview

    – need to look deeper code • do they use good practices? do they write tests? communication • how do they work with users? and with developers? • would I want to work with them? 20
  33. Summary

  34. Summary mutual assessment with focus on developer/developer • passionate about

    community, technology, novelty • look for that in others – diversity as a sign • spectrum to explore: superficial aggregates vs. public protocols 22
  35. Summary influences on adoption of technologies & practices • achievements

    can motivate to try something new • appreciation from peers motivates • inspiration from opinion leaders actively sought 23
