Standing items

    • Whenever updated numbers land, please screenshare and show the budget.
      • Link is in Keybase (numfocus_spreadsheets.txt)
  • open votes

    • 1 for core, 4 for staged recipes - expect 5 emails from voting system
  • 2022 Outreachy / GSoC

    • Ask each week: Any interested parties in owning this?
      • News after discussing things at Anaconda
    • Discussion 2021-11-03
      • If we want to do outreachy again we need a champion - Filipe can't do it next year. Same with GSoC.
      • GSoC is free to us
      • Outreachy costs us $$ ($6500). $6k for student, $500 for admin
      • Some interest from Jannis - he and Filipe will chat about possibly handing off
        • Trying to figure out what policy for interns at Anaconda - some overlap maybe. Jannis wants to pick Filipe's brain. Dave C. has also done this in the past at galaxy
      • (FF 2022-01-14) Folks. NumFOCUS is applying as an umbrella org for GSoC again. I won't be able to manage that again b/c I'll be doing that for my day job. If anyone is interested please reach out and I help you apply with NumFOCUS.
      • Anaconda is interested in funding outreachy ($6500-$7k) and helping with program managment (from new Berlin based staff)
      • Ideas
      • FF: Started with docs last time. this is more on our side. We're going to try next round. Was hoping to get someone to work on Grayskull, but Marcelo just had a kid so...
        • JR: Quansight has a summer internship program that could help out with some conda-forge stuff. Not going to do outreachy
      • DC: Current outreachy program is june-aug. need to submit community application (conda-forge is already approved) by a 25th of feb (but cf might not need to submit). project proposals will be due shortly after that. Something worth throwing out there, given outreachy's
      • DC: Any bandwidth in bioconda to support outreachy?
      • MRB: If I can get help reviewing applications, I can handle most of the mentoring
        • Jaime, Filipe, Jannis volunteered to help reviewing applications
      • Jannis can mentor a more technical intern (maybe doing grayskull)
