Edgerouter / EdgeOS / DoH / Security Settings

Notes

• It seems that every firmware update, whatever was done to get nextdns into the router, will be gone, so you will have to redo the steps or at least some, if you confirm that it has happened.
  • However there is locations where the config might be persisted on router reset.
  • /config/scripts/post-config.d/ or /config/user-data/
• I recommend not configuring the router through the UI, after reset, but by SSH after enablig it. That can prevent bad configuration, re-requiring the router reset.
• Make sure to have NTP enabled and configured. To avoid bugs.
• You can do through the UI CLI or using SSH, if you have enabled it and set a port.

Implementing complex numbers and FFT with just datatypes (no floats)

In this article, I'll explain why implementing numbers with just algebraic datatypes is desirable. I'll then talk about common implementations of FFT (Fast Fourier Transform) and why they hide inherent inefficiencies. I'll then show how to implement integers and complex numbers with just algebraic datatypes, in a way that is extremely simple and elegant. I'll conclude by deriving a pure functional implementation of complex FFT with just datatypes, no floats.
