• An open-source pick-and-place machine was announced with ~$450 BOM cost; full design files and a demo video are available at https://github.com/sphawes/index.  
• New high-speed DNA-PAINT fluorescent probes were highlighted that cut imaging time by 26×, eliminate the need for TIRF, and work on existing microscopes (preprint: https://www.biorxiv.org/content/10.1101/2020.04.29.066886v1).  
• A massively multiplexed protein-imaging technique using DNA-barcoded antibodies and fluorescent in-situ sequencing was shared (preprint: https://www.biorxiv.org/content/10.1101/2020.04.27.060624v1).  
• Discussion of digital holographic microscopy for low-cost metrology and full-depth focus using Raspberry Pi camera v2 or 4-lane CSI2 MIPI boards.  
• Participants debated the failure of transparent distributed-computing projects like openmosix/linuxPMI and considered reviving the concept via WebAssembly system APIs or Haskell/GHC integration for seamless off-loading of compute between devices.
