nemo™ 🇺🇦Academic consensus question on <a href="https://mas.to/tags/Signals" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Signals</a> safetyTL,DR: YES 100% ✅ Signal, a messaging protocol known for its end-to-end encryption, is widely regarded as secure. It is used by popular applications like WhatsApp and Facebook Messenger, serving over a billion users. The protocol includes advanced security features such as "future secrecy" and "post-compromise security," achieved through a technique called ratcheting, which updates session keys with every message sent" <a href="https://mas.to/tags/thread" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#thread</a> (1/4)

Pustam | पुस्तम | পুস্তম🇳🇵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.

Habrsignals в качестве альтернативы useState в ReactПривет, хабр! Больше года назад я впервые узнал про сигналы , а три месяца назад @Sin9k записал видео на эту тему. И поскольку сигналы по-прежнему обходят стороной, попробую немного исправить ситуацию) В материале будет использоваться обёртка signals-react , так как изначально рассматриваемая библиотека написана под Preact.<a href="https://habr.com/ru/articles/892730/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://habr.com/ru/articles/892730/</a><a href="https://zhub.link/tags/react" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#react</a> <a href="https://zhub.link/tags/signals" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#signals</a> <a href="https://zhub.link/tags/reactmemo" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#reactmemo</a>

HabrПонимая реактивные системы: искусство планирования зависимостейВ этой статье мы продолжим разбирать базовые концепции реактивности на основе идей и примеров, изложенных Райан Карниато (Ryan Carniato), автором SolidJS. Сегодня рассмотрим, как в реактивных системах планируется выполнение изменений производных значений. Большинство разработчиков воспринимают реактивность как систему событий. У вас есть некоторое состояние, которое обновляется, а все зависящие от него данные пересчитываются. В итоге это изменение проявляется через побочные эффекты.<a href="https://habr.com/ru/companies/first/articles/892582/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://habr.com/ru/companies/first/articles/892582/</a><a href="https://zhub.link/tags/javascript" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#javascript</a> <a href="https://zhub.link/tags/%D1%80%D0%B5%D0%B0%D0%BA%D1%82%D0%B8%D0%B2%D0%BD%D0%BE%D1%81%D1%82%D1%8C" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#реактивность</a> <a href="https://zhub.link/tags/%D1%80%D0%B5%D0%B0%D0%BA%D1%82%D0%B8%D0%B2%D0%BD%D0%BE%D0%B5_%D0%BF%D1%80%D0%BE%D0%B3%D1%80%D0%B0%D0%BC%D0%BC%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D0%B5" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#реактивное_программирование</a> <a href="https://zhub.link/tags/react" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#react</a> <a href="https://zhub.link/tags/vue" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#vue</a> <a href="https://zhub.link/tags/signals" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#signals</a> <a href="https://zhub.link/tags/solid" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#solid</a> <a href="https://zhub.link/tags/svelte" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#svelte</a>
