- 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
- [ ] change meeting time to 30 min in the new year, keep it biweekly
