The dads on this block have turned garbage day into an informal drum circle. This is why we need an HOA.

Don’t forget to disband the HOA in your mind, too

My 8yo crashed the HOA meeting and took notes for us.
I'm not sure if that's a parenting win or fail (raising NIMBYs?)

Channel characterization in screen-to-camera based optical camera communication
With the increase in optical camera communication (OCC), a screen to camera-based communication can be established. This opens a new field of visible light communication (VLC) known as smartphone to smartphone based visible light communication (S2SVLC) system. In this paper, we experimentally demonstrate a S2SVLC system based on VLC technology using a smartphone screen and a smartphone camera over a link span of 20 cms. We analyze the Lambertian order of the smartphone screen and carry out a ch…

MegaFold: System-Level Optimizations for Accelerating Protein Structure Prediction Models
Protein structure prediction models such as AlphaFold3 (AF3) push the frontier of biomolecular modeling by incorporating science-informed architectural changes to the transformer architecture. However, these advances come at a steep system cost, introducing: compute- and memory-intensive operators, 2D attention mechanisms, and retrieval-augmented data pipelines, which collectively hinder the scalability of AF3 training. In this work, we present MegaFold, a cross-platform system to accelerate AF…
