  • https://github.com/conda-forge/conda-feedstock/pull/315
  • WV: What is the performance cost of virtual package detection?
    • TH: Offering to do some benchmarking
      • TH: Doesn't actually have a GPU, so this may make things difficult 😂
  • IF: Please post benchmarks in the PR on conda-feedstock
  • WV: Could instead add a dependency to conda-build?
• (TH) Presenting about staged recipe contribution at the end of the month at https://meetup.doepy.org/

    • I'm curious about how I should go about recruiting new reviewers. I know there's a currently a need for more c/cpp reviewers. Are there other deficits I need to know about?
  • Should I have someone from conda-forge core review my slides beforehand? Or do I have everyone's blessing 🙏
• (LH) Native runners for RISC-V in conda-forge
