Gerrymandering and math

California’s proposition 50 turned out to be one of the most challenging voting issues that I have encountered, taking me a few days to think through. In the end it boiled down to this: if someone did a bad thing, should we do another bad thing to counter it?



During the process I also encountered some interesting related research, such as this podcast about math and redistricting (and social science more generally).

Sharing unpublished research work

Sharing a research work that is not yet published (not even a preprint on arXiv) can have several benefits, such as receiving early feedback, increasing visibility (especially for junior researchers), and attracting potential collaborators.

On the other hand it also has some risks, such as being scooped by others or jeopardizing anonymity during the review process or public disclosure for patent application.

To maximize the benefits and minimize the risks, I suggest sharing only with trusted colleagues who have the expertise to provide constructive feedback and ethics to maintain confidentiality. If the paper is still under review, check the conference/journal policies (e.g., this for SIGGRAPH). For patent application, any public disclosure will invalidate international filings but there is a one-year window for US filings.

Diwali party vultures and scavengers

The line for the Diwali party was too crowded earlier in the afternoon, so he went there later around the closing time, when only a few vultures and scavengers remained, to get some food.

Rooftops jumping dream on October 4, 2025

Chased by a tiger, a lion, and a leopard.

I attempted to depict the dream by drawing it before realizing that it could be faster to collage from existing images. Idea is more important than execution, at least for this particular case.
