  1. The methyl methacrylate tank incident in Garden Grove, California has resurfaced one of my pet peeves.

    According to mainstream news journalists, anything that is a "chemical" is "highly toxic". It's the end of the world. There isn't enough drama in the world.

    This stuff is not great - it's a skin irritant, and the fumes can irritate mucous membranes like the eyes, but it is *not* instant-death-on-a-stick. The explosion they were worried about was far more dangerous for its explosive effects than for the chemical release.

    It's no dimethylmercury or hydrogen fluoride or dioxygen difluoride [1]. Heck, it's oral LD50 is something like 7g/kg - so an adult would have to *eat* almost two pounds of the stuff to have an even-odds chance of dying.

    Stop trying to terrorize the public, journalists. Do your damned jobs.

    [1] Expose it to most things, even at almost 200 degrees C below freezing, it explodes. Try to put out the resulting fire with water, it explodes. Try to put out the fire with sand, it *sets the sand on fire*.

  10. Ваша модель показывает 95% accuracy и при этом бесполезна: метрики для несбалансированных классов

    Модель может показывать 95–99% accuracy и при этом не решать задачу: особенно если редкий класс важнее всего для бизнеса. В статье разбираем, почему accuracy ломается на несбалансированных данных, как читать precision, recall и F1, зачем смотреть PR‑кривую и confusion matrix, а также как подбирать порог классификации с учетом стоимости ошибок. Понять ошибки

  14. The 2026 Civil Defense SPR. What Changed?

    I also go into the changes I made to my Civil Defense Rifle build over the course of the last year. The goal was to improve the shootability and overall practicality of this lightweight, affordable Special Purpose Rifle build, without sacrificing any of the original goals (SPR capability/accuracy, sub 10 lbs, sub $1000)....
