Agentic Programming - navigation There are fans and haters of LLMs and agents. I'm neither. I'm just working with these tools, much like I used to work with programming languages and other tools. Little by little, this c

3D-printed Dragon Curve Once I stumbled upon a big glass box in the middle of the App in the Air office. I asked, "What is it?" Turned out it was a 3D printer. An expensive one. I didn't get a believable answer about wha

Friday trash Be careful, the first photo is really a kind of trash. 100 kilometers north of Moscow, kids are playing with a dead snake. If your toys were wooden, you were lucky. Near Zvenigorod there is a bunch of identi

Geometric proof of an algebraic formula In a friendly chat I saw an idea for a nice toy. It's a well-known thing, and you can check the [post](<https://t.me/geometrykanal/363>) with a magnificent picture, and a beautiful

Self-portrait To generate such a magnificent picture, say: "Redraw my photo in MS Paint style, with some likeness, but also off in a confusing way..." I'll try to write about myself under a similar prompt. The beginning

Sorry for the pause in posts. Over the holidays I read the whole new Pelevin book and analyzed Pearson-friendly institutions. Also, my daily work project buried me under a lot of hands-on tasks. Please help me decide wha

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
