So while mastodon.social is down, one can flex some of that #fediverse power and dust off long forgotten alts :)

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: http://bit.ly/22kbNfi

RE: https://cosocial.ca/@timbray/116891415911514354
You know what? Whenever people may ask me why I heart #Mastodon big time and why I'm no longer interested in traditional enshittified #SocialMedia tools, I'm going to start sharing this fabulous blog post by @timbray that pretty much nails it, as far as I am concerned.
In fact, for those folks who were using Twitter circa 2006 to 2010 it's a lovely trip down the memory lane of what #Web20 promised back then 👌🏻😎

I had an interesting conversation on here recently that made me realize that maybe not everyone who uses Mastodon knows that you can use filters as a way to add content warning to other people's posts?

#Mastodon my friend @skelders333 is still in dire need, and things are getting worse as there hase been no movement at all
If you have spoons, can you grab this flyer and share it around?
If you don't have that many spoons can you #Boost
If you have financial security as in a roof and food that is mostly dependent on YOUR labor which provides income can you contribute?

Question, does anyone have a link to a 'how does Mastodon work' explanation (or 'how does the Fediverse work') that is understandable for people who still use Instagram or Facebook, for example? #dta #mastodon #fediverse
