  1. How did `up n` become a must have function?

    I just scrolled through over 20 bash and zsh configs on GitHub, and they all had the `up n` function.

    mine is simply:
    ..
    ...
    ....
    .....

    😂

    Might scrap that and add `up.bash` to my config.

  6. What's the best string representation of a function? Comparing with other PLs:

    Python: <function __main__.add_one()>
    JS: [Function: addOne]
    Clojure: #function[user/add-one]
    Scheme: #<procedure add-one (x)>

    I'm currently thinking about <fun add_one() foo.gdn:123>

  7. Every song in the Glass Ceiling Records catalog carries its own history, lineage, and emotional #function. These posts are designed to help readers understand not only the music itself, but the creative and anthropological framework that shapes the entire #ecosystem.

  8. #RedFlag 1: You Are Treated as a #Function, Not a Human

    A person relating to you as a role — “the helper,” “the strong one,” “the responsible one,” “the emotional one” — is not relating to your #complexity.
    They are relating to the function they need you to perform.

  9. Динамический полиморфизм для свободных функций: еще одна практика из С++ для машинного обучения

    Привет, Хабр! Я Кирилл Колодяжный, разработчик систем хранения данных в YADRO и ML-энтузиаст. Продолжаю рассказывать о паттернах С++, которые легко адаптировать под задачи машинного обучения. В этой части поговорим о динамическом полиморфизме — технологии, которая помогает объединить интерфейс для запуска вычислений с разными условиями. Ссылку на первую часть найдете в конце статьи.

  11. #Rotating a #Point about the origin, through some #Angle θ is something that is taught in school #maths class, usually in #CartesianCoordinates, by multiplying the #Coordinates by a the rotation #Transformation #Matrix. What’s not generally taught is that you can apply the same transformation to any #Function y=f(x). All you need to do is replace
    x by xcosθ + ysinθ
    and y by -xsinθ+ysinθ.

  12. Обходим подводные камни работы с UDA в коде на Lua для ScyllaDB: дружим Java-драйвер и пустые значения

    Привет, Хабр! Мое имя Александр Коваль, я разработчик IoT-сервисов в МТС Web Services. Сейчас ScyllaDB поддерживает ограниченное количество функций, в том числе агрегационных. В стандартном наборе: min, max, count, avg. Но ее функциональность расширяется двумя типами пользовательских функций : скалярными (scalar functions) и агрегационными (aggregate functions). Первые работают со значениями одной строки, а вторые — нескольких. Реализовать такие функции можно на Lua или Rust. В процессе работы с агрегационными функциями можно столкнуться с тем, что ScyllaDB и Java-драйвер по-разному обрабатывают пустые значения. В этом посте я расскажу, как это можно решить относительно просто и без сложных дополнительных телодвижений. Для примера возьму код на Lua и покажу, как он реализуется в виде функции ScyllaDB. Дисклеймер: этот материал написан на основе личного опыта — все решения получены методом проб и ошибок. Конструктивные предложения и советы по их улучшению приветствуется. Код с примерами и ссылки на ресурсы можно найти у меня в репозитории GitHub .

  13. The Fourier Transform is a mathematical operation that transforms a function of time (or space) into a function of frequency. It decomposes a complex signal into its constituent sinusoidal components, each with a specific frequency, amplitude, and phase. This is particularly useful in many fields, such as signal processing, physics, and engineering, because it allows for analysing the frequency characteristics of signals. The Fourier Transform provides a bridge between the time and frequency domains, enabling the analysis and manipulation of signals in more intuitive and computationally efficient ways. The result of applying a Fourier Transform is often represented as a spectrum, showing how much of each frequency is present in the original signal.

    \[\Large\boxed{\boxed{\widehat{f}(\xi) = \int_{-\infty}^{\infty} f(x)\ e^{-i 2\pi \xi x}\,\mathrm dx, \quad \forall\xi \in \mathbb{R}.}}\]

    Inverse Fourier Transform:
    \[\Large\boxed{\boxed{ f(x) = \int_{-\infty}^{\infty} \widehat f(\xi)\ e^{i 2 \pi \xi x}\,\mathrm d\xi,\quad \forall x \in \mathbb R.}}\]

    The equation allows us to listen to mp3s today. Digital Music Couldn’t Exist Without the Fourier Transform: bit.ly/22kbNfi

  14. My wife was working through finding the derivative of the #exponential #function #exp(x) from first principles.I was made aware that she hadn’t actually seen why the number e=2.7128… was the #base the of the function and that that’s what you need to start with. In fact, that means one must actually start by finding the first differential of a general #logarithm and find #e from there. Once you’ve find the #Derivative of #lln, the #derivative of the #ExponentialFunction is straightforward. (1/2)

  16. Effects of #Alkaline #Solutions on the #Structure and #Function of #Influenza A Virus

    Source: Viruses, AbstractInfluenza A virus (IAV) infection contributes to high annual morbidity and mortality, thus necessitating measures aimed at protecting against the disease. Alcohol-based disinfectants are commonly used to inactivate IAV, but they have several undesirable properties. In search of other means which would inactivate IAV, we focused on the effect of alkaline…
