@rzeta0 my friend, what do you think about the code using np.roll() (in the linked sketch)?
I'm afraid it would be a bit hard to explain on a short class. So I'll use the simpler inefficient function...
The next big step in efficiency would be using #scipy I think:
def count_live_neighbors(status):
"""Counts the number of neighboring live cells"""
kernel = np.array([
[1, 1, 1],
[1, 0, 1],
[1, 1, 1]
])
return scipy.signal.convolve2d(status, kernel, mode='same', boundary="wrap") -

CW: Advent of Code 2025 Day 10 Spoilers
Today I "cheated" and used scipy's MILP solver for Part 2. Discretion is the better part of valor, as they say, and writing a constraint solver by hand is not what I had planned for this Wednesday morning. The existence of `uv` to deal with all the dependencies makes reaching for scipy for even little scripts like this an easy choice.
Part 1 was trivial. Treat the lights and the buttons as bitmasks and recognize that buttons XOR themselves so they're pressed at most 1 time each. Generate the smallest combination of buttons that XOR to the target.
Part 2 is probably solvable via something like DFS before the heat death of the universe, but it would take way too long. Instead, I used scipy's integer linear programming solver, defined the constraints, objective, and bounds, and let it do its thing.

The #Volcanic Isles . A brief history of volcanism across The British Isles.
Quite pleased with how this one turned out.
Location of volcanoes taken from wikipedia (spotted a mistake and got to make an edit to wikipedia in the process); fault lines from the #BGS 625k bedrock dataset and the IE GSI 500k Bedrock Geology for Ireland. Font: League-Spartan by the League of Moveable Type.
#requests, #pandas and #geopandas for scraping and wrangling.#scipy for making the proximity surface (that's the colour scheme), #matplotlib for plotting. With all labeling done manually in #inkscape.
EDIT: I've been kindly and helpfully informed that (a) Ben Nevis' age is closer to 399 Ma; (b) some are missing; (c) others perhaps shouldn't be there; (d) it's complicated. So, maybe don't use this map to make any strategic decisions.

Все об устройстве Q65 с примерами на Python (часть 1)
Q65 — цифровой протокол, разработанный Джо Тейлором (K1JT) и его командой в 2021 году для проведения минимальных связей в условиях сложных трасс прохождения радиосигнала, в том числе для проведения связи через отражение сигнала от Луны, где сигналы не только очень сильно ослабевают, но и имеют Доплеровский разброс. В этой статье будут рассмотрены подробности работы протокола. Статья может быть интересна радиолюбителям, как знакомым, так и не знакомым с Q65, а также тем, кто хочет понять устройство этого протокола.

Scipy is a phenomenal library. It's not every day that one can beat its performance by 1-2 orders of magnitude. Today is that day, though!

@hisold Citing a plain website or GitHub repo is kinda unprofessional. Many widespead software packages have a publication that is well citable, e.g. #sympy has this one with a proper DOI: https://doi.org/10.7717/peerj-cs.103, same for #numpy, #scipy, #matplotlib, etc. Some have at least a #Zenodo entry (with a DOI) to be properly citable. #PlatformIO apparently has none of those.

Did you know the main driver behind NumPy/SciPy didn't get tenure? 🧐
I guess that board was wrong about Travis Oliphant.Literally everything I did in my scientific work since 2008 heavily depends on work like (and in my case particularly) NumPy/SciPy. #numpy #scipy #python #ScientificComputing

My first experience with #chatgpt5.
I queried how to write some #python code to write out unformatted, binary files so my #fortran code could read it.
Proceeds to give me a load of #NumPy code. Completely neglects to mention the #SciPy FortranFile class that can trivially read and write, and appears on the first page of a search.
This is going to be a bumpy ride!

Comparing a naive "nearest neighbor" #TravellingSalesmanProblem solver with a #2optSwap one, adding a #DelaunayTriangulation mesh, it shows how often the better solution falls into the triangulation!
The #py5 sketch is interactive, you can generate other random nodes and move them around dragging with the mouse.

Индуктивная статистика: доверительные интервалы, предельные ошибки, размер выборки и проверка гипотез
Одной из самых распространённых задач современной аналитики является формирование суждений о большой совокупности (например, о миллионах пользователей приложения), опираясь на данные лишь о небольшой части этой совокупности - выборке. Можно ли сделать вывод о миллионной аудитории крупного мобильного приложения, собрав данные об использовании лишь для 100 пользователей? Или стоит собрать данные для 1000 пользователей? Ответ интуитивно прост и понятен: чем больше данных есть в наличии, тем более точными будут прогнозируемые результаты для всей совокупности. Какую вероятность ошибиться при анализе мы можем допустить: 5% или 1%? Относятся ли две выборки к одной совокупности, или между ними есть ощутимая значимая разница и они относятся к разным совокупностям? Точность прогноза и вероятность ошибки при ответе на эти и другие вопросы поддаются вполне конкретным расчётам и могут корректироваться в зависимости от потребностей продукта и бизнеса на этапе планирования и подготовки эксперимента. Рассмотрим подробнее, как параметры эксперимента и статистические критерии оказывают влияние на результаты анализа и выводы обо всей совокупности, а для этого смоделируем тысячу A/A , A/B и A/B/C/D тестов .
