#TIL about @frequency, a federated photo-sharing app;

"I'm trying to be very upfront. Like, OK you're going to have to pay for this service. But I really want to make it as affordable as possible. I want to give you options to pay for your family and friends, to bring everybody in if there's someone that can't pay for it ..."

Le silence du #fediverse.

Hackers' Pub · “조용한 연합우주” 문제를 해결하는 두 가지 접근법: 대화 백필링 메커니즘이 글은 연합우주(fediverse)에서 발생하는 "조용한 연합우주" 문제, 즉 대화의 일부만 보이는 현상의 원인과 해결책을 탐구합니다. ActivityPub 프로토콜의 분산 특성으로 인해 대화가 여러 서버에 분산되어 저장되면서 발생하는 이 문제를 해결하기 위해, 답글 트리 크롤링과 컨텍스트 소유자 기반 방식이라는 두 가지 주요 접근법을 제시합니다. 답글 트리 크롤링은 모든 답글을 순차적으로 가져오는 방식이지만 네트워크 취약성과 작업량 증가의 단점이 있고, 컨텍스트 소유자 방식은 대화의 원 작성자가 대화 내용을 관리하는 중앙화된 접근법이지만 컨텍스트 소유자에 대한 의존성이 높다는 단점이 있습니다. 또한, 모더레이션 패러다임의 충돌과 상위 전파 누락 문제와 같은 논쟁점을 지적하며, 주기적 크롤링, 사용자 트리거, 멘션 기반 백필과 같은 추가적인 백필 메커니즘을 소개합니다. 마지막으로, FEP 수렴 논의와 구현체 간 협력 현황을 통해 향후 개발 방향으로 하이브리드 접근법의 표준화를 제시하며, 다중 전략 구현, 리소스 관리, 모니터링 및 로깅의 모범 사례 가이드라인을 제시합니다. 이 글은 연합우주가 더욱 풍부하고 연결된 소셜 네트워크로 발전하기 위한 노력과 사용자 경험 개선의 중요성을 강조합니다.

I still recall the day several decades ago when I, as a young #ElectricalEngineering undergrad, was introduced to the concept of "negative #frequency". I was unsettled. I suppose my reaction to the idea of negative frequencies was like the Medieval mathematicians' reaction to Fibonacci's discovery of negative numbers. But after my head was properly bashed in by a couple of homework problems, this concept became as natural to me as the negative number and the negative time.

I am curious how civil, mechanical, and other engineering fields deal with the concept of negative frequencies.

To receive by #radio #reticulum #rnode #announces on #lora radio one needs to have the same 4 radio parameters as the announce: #frequency #bandwidth #spreadingfactor SF #codingrate CR
-> #meshchat permits any number of #rnode interfaces !
To hear the most announces, does it make sense & is it possible to set up several e.g. 5 #lora #radios with same frequency: 869.525 MHz
bandwidth: 250 kHz but
each with different SF & CR? Would one be able to receive more announces that way? Would it work?

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