Recently, I undertook a rather challenging task: to fully reproduce a paper titled “Physics-informed deep generative learning for quantitative assessment of the retina” on a High-Performance Computing (HPC) cluster. The core software repository for this paper is RetinaSim. The goal was not merely to run the code, but to completely replicate its complex software stack and simulation workflow in a strictly managed computational environment, one that likely differed significantly from the original developers’. This blog post will chronicle my entire journey from the initial attempt to the final successful run, focusing on my chain of thought as I diagnosed and resolved a series of tricky issues. ...

Recount Problem The recent schoolboard elections were hotly contested: a proposal to swap school start times for elementary and high school students, a controversial new dress code proposal that bans athletic clothes in school, and a proposal to raise real-estate taxes to pay for a new football practice facility, and the list goes on and on. It is now hours after the polls have closed and a winner has yet to emerge! ...
