LiFX CoAP Bridge

This document is outlining the schema for a CoAP bridge for LiFX devices.

• /discover - Post to force rediscovery of LiFX equipment.
• /d/
  • all/
    • raw - Send a raw frame to all devices.
• power

Congress Reimagined
===================

This is a document which summarizes my thoughts on how congress could be organized differently
in order to allow for more than two viable political parties.

Senate
------

The senate would be changed quite dramatically. Instead of each state voting for two

Hardware encrypted USB ideas

There are hardware encrypted USB sticks on the market, but a few things make me uncomfortable about them:

• They all involve running an executable on the computer you want to access the data from.
• There is no standardized mechanism for how the app takes your password and communicates that to the microcontroller on the encrypted drive.

Instead of using a vendor-provided executable, I propose a mechamism which allows the encrypted USB drive to be securely mounted on any machine that has a web browser.
