автор tg: @PyotrAndreev 27 My Exp 2025 Resume Python unites people. Your given value increase trusting you and give you new: - communities & contacts - prof.knowledge & culture understanding - opportunities You comeback with a new life rhythm & resource state; you see the World and opportunity map much bigger, where you live 

No One Knows All C/Python open to your mistakes 

автор tg: @PyotrAndreev 29 What community actually gives (and costs) ? - community with prof.unite point - open: - connect with core.devs - prof.society - Steering Council 

автор tg: @PyotrAndreev 30 What community actually gives (and costs) ? How to be useful for community - mentoring you and yours: PyConUS --FT person - volunteering: free conf.enter - PSF: involve into community more - conferences: speaker - CPython contribution 

автор tg: @PyotrAndreev 31 aim #1: turn personal growth into Python impact and get momentum back - becoming familiar with big difficult project: - your contributing: - - understanding how it works -- growing as specialist - - visibility & hook for employers: - - Donghee NA - - one more core dev - - Linux maintainer: NVidea your Python contribution -- your grow 

автор tg: @PyotrAndreev 32 aim #2: speaker POV conference energy into measurable impact: contributions | collabs | outcomes new knowlages & ideas & collaboration points: - geeks & industry.prof.: - photos: keyboard, forest fire & ML, phone nets & servers computations - Singapore: (photos) badges -- collaboration points - job offers -- team collaboration - socialization and society introducing

автор tg: @PyotrAndreev 34 aim #3: Python's future: hard community questions open source -- not about money -- wrong open source – base for the world: sustainability, motivation problem – core-devs ecosystem for people involving?: need constant gradient force to people for growing - status popularity: core-devs – famous in Py community but outside ? 

автор tg: @PyotrAndreev 35 aim #3: Python's future: hard community questions do Py community has full time employees for? - marketing-brand strategy - marketing to companies - contribute to Python should be is very high respectful - maybe I don't see the all picture, but why companies investing only if they need some features in python? - brand sails & company investing (why: Donghee's initiative?) 

автор tg: @PyotrAndreev 36 what people think: money afraid contributing with grants & rank system money motivation: pay money to cor-devs: - family time (play with your children) - earn extra money - or contribute to CPython Why do we lose people who chose the 1st & 2nd ? Also, we compete with other projects → let's they contribute to our project: CPython aim #3: Python's future: hard community questions 

автор tg: @PyotrAndreev 37 World play in capitalism game, How can we "play" better game via the rules? need more money motivations for contributors aim #3: Python's future: hard community questions

автор tg: @PyotrAndreev 39 not transparent system of status growing in community (0 --> core-dev): - people need understand revard/cost track of growing - gamification – support small step grows aim #3: Python's future: hard community questions 

автор tg: @PyotrAndreev 40 Toolkits education → CPython contributors (my practice) need strong stream of new blood: how we can involve them? 

автор tg: @PyotrAndreev 41 Toolkits education → CPython contributors as a part of advanced Python courses We need: - support system (invest money to support): - cells curators with deep knowledge, who support teachers & education streams: to contribute to CPython - education system/universities who need the contributions as KPI people will not be a lot from on uni., but many people from many universities -- involve new people to contribution
