Friday shitposting. Old Moscow photos. It seems that I’m stuck in a deep perfectionist loop, endlessly polishing my post about stochastic wandering. Meanwhile, let me share some trash photos I took about 20 years ago.
Pi ! While I'm preparing a post on random nature of ROC, let's celebrate this point. I was wondering which next number would trigger me, tried to check perfect squares, cubes... Nothing clicked. But today I saw 314 and i
Friday shitposting. 1 May Thirty-five years ago, in April 1991, I started this project. The idea was quite simple: use the `DRAW` operator in QBASIC to draw a stylised “1 MAY” banner. The `DRAW` operator offered only a s

Integration: Codex and JupyterLab I tried a few ways of working with an LLM inside JupyterLab: magic commands, editing files through Codex, even using Cursor. All of them felt like different shades of “this is not what I
Friday. Trash. Rescue in Midair. It’s an ancient story. I probably read it sometime around 1993, and it’s probably apocryphal. It doesn’t matter. The storytelling is magnificent. A demonstration performance by parachutis
Plan: from school-level math to a March 2026 arXiv The stakes turned out to be higher than I expected. Our quiet little discussion of the Titanic dataset may have suddenly wandered into publication-level territory. You c
Quick recap: We have a model that gives scores of -1, 0, and 1. When we plot the ROC curve, we get a graph with 4 points and an AUROC of 56%.
Let’s rock ROC All this time, it bothered me that the ROC in [the post](<https://t.me/phys_math_dev/164>) contains only three points. I’ve been thinking about this situation for a while, and I think I’ve found a small bu
