Programming Media Keys on the Ducky One 2 Skyline

To use media keys on the Ducky One 2 Skyline, you must record a macro to bind the media function to a hotkey combination, i.e. Fn plus some key.

Example

Important: In the instructions below, "Press X+Y+Z" means press and hold key X, press and hold key Y, press and hold key Z in that order, and then release all three.

As an example, to bind Fn+PgUp to the play/pause media function:

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

If you prefer VirtualBox or aren't running OS X, here are some instructions and a script to help you get started with SmartOS under VirtualBox. If you use VirtualBox, skip the first section and read the section on how to get the Node.js SmartMachine up and running.

Running SmartOS under vmware Fusion

1. Start by downloading the latest live image
2. When you run the new VM wizard, select "Continue without disk" on the first screen of the wizard.
3. Select Sun Solaris / Solaris 10 64-bit on the next screen.
4. You're going to get dumped to a config screen when the live image starts up, choose DHCP for the networking and defaults for everything else.
5. Pretty much the first thing you're going to want to do is figure out how to SSH into the box once it boots and creates its storage pools, because trying to do stuff in the virtual console is miserable. There's no cut and paste
