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.

f^(ξ)=f(x) ei2πξxdx,ξR.

Inverse Fourier Transform:
f(x)=f^(ξ) ei2πξxdξ,xR.

#Amplitude, the studio behind #Humankind, has announced last weekend thesixthaxis.com/2024/11/09/am that they will become an independent studio, not anymore affiliated with #SEGA. The owners apparently bought the company back, and will probably be looking for another interesting project. Join us to discuss this here: forums.civfanatics.com/threads

When your #iOS app doesn't have user accounts (no sign up/log in & no uuid provided by a server), how do you manage identity in analytics and reporting tools? Leave everything anonymous? Pass a UUID as a custom attribute?

I currently create my own UUID that I use for #RevenueCat, #Amplitude and #Sentry. This way I can find a user across the different tools for support. But I don’t handle multi devices: the same user will count multiple times and I won’t have a way to view the full user journey.
