Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

Not all that interesting but I recently built a server for 2FA.

It mainly consists of a simple CLI utility that generates TOTP codes using an AES encrypted lookup table of secrets.

I piggybacked access to this off an unrelated web site and it is now readily available from any device if you can provide the decrypt and lookup key and know the URL.

That's pretty nifty. Security first.
