TFWR. Drone coordination. Last time we discussed how to create drones. Today let's discuss how to coordinate their activity. In the game there is quite a limited number of tricks that allow you to coordinate drones. Let'

The First Vibe Coding Project In the chat about TFWR, one of the subscribers asked how to learn Python and HTML. I answered like this: “Feel free to vibecode a small application that uses Python, HTML, and CSS, and then

Topics request Now I have a list of topics for the nearest posts. * video for the first vibe coding project * why binary features are bad extrapolation features (explanation why quality goes down when interpolating featu

LLM in education Sorry for this quite a rather unoriginal topic, but it bothers me. I'm teaching my son programming. So far we have discussed it in a classical way: variables, loops, algorithms. We spend hours discussing

Ultraviolet lamp In my other channel I published a [post](<https://t.me/alina_yerevan_js/133>) about vanished place where I worked in 1991-1992

GBDTE. Culprit is found. I started to dig really deep and, with the help of the iron friend, I checked several hypotheses. I found the optimal expression for the ideal model for this dataset. And this result is worth a s

TFWR. Spawn drones. In "The Farmer Was Replaced" game there is quite an interesting option - one can spawn drones in order to operate the farm more efficiently. This option is advanced because of language tricks and game

Bubble sort of one cacti column in TFWR This game provides quite a nice opportunity to see how different sorting algorithms work. In this post, let's discuss the famous bubble sort. You can check the [code](<https://gith

Logloss dataset for GBDTE It seems that I repeated the post about dataset generation twice, so let's move on. The picture shows lift graphs for 16 features. One can see that the lines are uneven - it's because of randomn

GBDTE: LogLoss dataset My approach with the synthetic MSE dataset was successful. I created it, and all experiments gave me quite expected results. The next frontier is a synthetic dataset for testing the logloss functio

TFWR. Labyrinth Let’s think about the labyrinth problem in The Farmer Was Replaced game. First of all, let’s state it. We have an 𝑛×𝑛 labyrinth, where n = get_world_size(). In position measure() there is a treasure. Our

When is a door not a door? I first heard this joke in the 1997 animated movie Anastasia, and it’s stuck with me ever since. In the film it’s treated like one of those classic jokes everyone’s supposed to know. Do you kno

Riddle of the day "What number, when you remove one letter from its spelling, transforms into an even number?" UPD: There are slightly different options for this riddle, like "I’m an odd number. If I lose one letter, I b

In my other channel I published post about physical exposition which my father and I found in 1988. Quite an exclusive [material](<https://t.me/alina_yerevan_js/122>) . In Russian.

GBDTE log‑loss dataset In this post I want to solemnly declare: I'm not a mathematician. My friends who are, I'm totally sure, would solve this problem without effort using Bayes' formalism. I can only wave my hands. So,

Big MSE dataset. Depth of trees. There are 128 groups in the Big dataset. And to distinguish them perfectly, it's necessary to use exactly 7 binary features. Why is it so? Because when we add one more level to a decision

Big MSE dataset for GBDT In the previous post I demonstrated a small dataset that shows how GBDT works. Now I want to present you quite a big one. There are 10 000 points in it. I wasn't happy with the quality of the tex

Liquid Nitrogen Station An attentive reader of one of my previous posts about the diamond plate in an electron microscope could notice a repetitive note: let's pour liquid nitrogen here, let's pour liquid nitrogen there.

Torus navigation Problem statement: issue control commands on torus map to navigate bot to a given point. Essence * pythonic (x2-x1) % n gives eastward toroidal distance * easier to think in "direction first" terms * go_

Dawn of the day It dawned on me today that Harlequin ↔️ Harley Quinn. An example of paronomasia (a pun)—more specifically, it works like an eggcorn/mondegreen for a proper name
