      • Crank up the RAM! But only so much scaling

      • Minimal SQL writing

        • Searchlight.jl: Julia ORM layer within

      • Is Genie like a shiny?

        • No, more of a full-stack

        • Goes beyond just visualization dashboards

    • Sequencing data

      • Equally data

      • Everyone uploads data in slightly different ways

      • Make simple ways to pull that data

      • R Conductor –> JuliaConductor?

        • Would make genomic pipelines within Julia pipelines a lot easier

      • We need to understand the underlying structures

      • One of the big pain points

        • Often to have roll your own

    • EpiR –> EpiJ?

      • Power calculators

    • Co-founder of start-up

      • Found unmet need for remote monitoring for neuotropenia

      • Non-invasive screen for neutropenia

      • Device runs Julia

      • Pain points:

        • Testability of hardware

        • LOTS of CI – bit of a pain

        • How much repetition happens in CI

      • Part of the problem for these problems:

        • There are still going to be folks who use the same organizations

        • Overcoming inertia to do the same or similar things in Julia

        • Wrapping around Julia?

          • Bringing it into the R ecosystem

          • Leading to big impacts for callable things from R by having smaller static binaries

          • Wrapping Julia packages in R

        • N3C – National COVID Cohort Collaborative

          • Went to many healthcare systems across the US to get COVID data

          • Shelled out to Palantir

          • Open source tools within the ecosystem

          • JuliaHub has Boeing board member

            • Trusted within security community

            • Could help in this situation

  • Thoughts on how to address some of these problems

    • Using other packages outside of Julia

      • If you have some way to wrap around it

      • Getting support

      • PythonCall.jl or RCall.jl

        • Not clear how to make this compositional

    • The paradox of compositionality

      • Blog posts go a huge ways to solving problems

      • Tutorials showing how things can be combined together

      • Promotional type material

      • Nice docs are nice

    • The Julia Blog itself

      • Mentions JuliaBloggers but doesn’t help with guiding users to read

      • Blogs need to go on as official blogs

      • Julia Forem – is it maintained?

        • Hook into the tags from blogs

        • Cross-posting where appropriate

    • How to learn Julia within the context of health

      • Carpentries for learning resources
