Hi everyone!

I started a shorts-series about differential forms. This is part 2 so far. I also have a part 1: https://youtube.com/shorts/J20AI3iE4OM

These videos are supposed to be short, concise and most importantly fun, while still being correct! (If you spot a mistake, please let me know)

I have so far introduced differential 1-forms in the previous video, and now I defined the exterior algebra which I used to introduce differential k-forms. Next up, I wish to define the exterior differential and hopefully some day I will also get to Maxwell's equations and de Rham cohomology (but this might take a while).

All feedback is warmly welcome!

Dear all,

I have great news to share! Previously, using the fingerprint reader on ROG Flow X13 (GV301QE, GV301QH and GV301RA) always/mostly failed^(1).

I finally managed to get the fingerprint reader to work on Linux^(2). This allows for fingerprint based authentication (no more typing passwords!).

I built this on the source code that filip-rs provided^(3).

Example usage:

example usage of patched libfprint to successfully validate sudo usage

Installation:

If you use NixOS, you can use this snippet to get my patched driver:

services.fprintd = {
      enable = true;
      package = (
        (pkgs.fprintd.override {
          libfprint = pkgs.libfprint.overrideAttrs (oldAttrs: {
            src = pkgs.fetchFromGitHub {
              owner = "quoteme";
              repo = "libfprint";
              rev = "0e9498eb4821ed43e26102179bae2728fb4f05ac";
              hash = "sha256-XN+VyKukunFw2aAKCQDaa7jBTc6cxszsxb0Elar7Pzg=";
            };
          });
        })
      );
    };

For other distros, please check your distros manual and use this repo to build libfprint: https://github.com/Quoteme/libfprint.

Support:

It would matter really much to me, if you could star my repo https://github.com/Quoteme/libfprint

please star the repo
