- Meeting Minutes
    - Micah ran Zarr v3 tests
        - Zarr compression ratio question 
            - Very suspicious 2x compression ratio on raw(!) Zarr
        - transfer speed question - need to switch to Zarr v3 container
            - Zarr V2 containers (the default "ZarrBlosc1...") do not support sharding
        - Dropping ~2% of frames with Zarr devices (vs. 0 with benchmark Tiff)
            - Larger chunks tend to drop more frames, compression tends to drop more frames
        - BloscLZ4 is running slightly slower (we say by virtue of dropped frame percentages) than BloscZstd
        - Alan shared the doc site, [test_zarr](https://github.com/acquire-project/acquire-python/blob/main/tests/test_zarr.py#L148)

    - [hackathon shared doc](https://docs.google.com/document/d/1Y0mZX9Uxh36gm9GHYW32cHDQwk4jBn42zCsAE0-gb8U/edit)
        - Karl is supportive
        - AI's comms won't have the bandwidth for website etc.
        - first half: participants share their projects and pain points, recruit people to the solutions
        - second half: work on solutions
        - make sure key people (e.g. MM community) can attend, engage early 
        - should hardware vendors be involved? 

    - retro
        - Achieved
            - driver support for the camera
            - implementing Zarr with sharding, v3
            - Acquire open sourced
            - AIND publication
        - Missed
            - Acquire yet to be the exaSPIM pipeline
            - multi-scale is yet to be the differentiator
            - getting runtime solid
            - imaging meeting workshop had unexpected outcome
            - Acquire did not get the new engineer, will restart the search
        - Will work on
            - multi-dimensional acquisition (XYZCT)
            - get Acquire into solid state for broader announcement
            - streaming to s3 directly 
            - major goal of hackathon is to bring the community together, (1) understand what people are working on and are comfortable with it. (2) build/identify new solutions
                - Talley, Curtis, Doug(?)
            - 3/13 to discuss progress with Karl et al.
        - Want
            - Acquire + hardware dissemination


- Action Items
    - [ ] Nathan & Adam & Chi-Li: short list individuals for invte/newsletter blast
    - [ ] Chi-Li: reach out to CZI comm team for hackathon support
