Commit Message Guidelines

Goals

• allow generating CHANGELOG.md by script
• allow ignoring commits by git bisect (not important commits like formatting)
• provide better information when browsing the history

• (:identity req) is auth backend independent way to access user data
• login and logout implementation depends on auth backend

Programming Media Keys on the Ducky One 2

To use media keys on the Ducky One 2, 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:

Thread Pools

Thread pools on the JVM should usually be divided into the following three categories:

1. CPU-bound
2. Blocking IO
3. Non-blocking IO polling

Each of these categories has a different optimal configuration and usage pattern.
