# based on a script from a now deleted askubuntu answer on this question http://askubuntu.com/questions/71863/how-to-change-pulseaudio-sink-with-pacmd-set-default-sink-during-playback
# the script linked in the answer is still available at https://github.com/mpapis/home_dotfiles/blob/master/bin/mypa though

# dependencies: pulseaudio pacmd awk xargs grep volumeicon
# optional dependencies: zenity (for gui switch)

# this script assumes you are using volumeicon as a tray icon and will restart it on switch
# if you do not use volumeicon you should remove the 2 lines in switch_sink()

Please include a repro

You probably arrived here because of a curt message in response to an issue you filed on a repo that I contribute to. Sorry about that (particularly if you filed the issue long ago and have been waiting patiently for a response). Let me explain:

I work on a lot of different open source projects. I really do like building software that makes other people's lives easier, but it's crazy time-consuming. One of the most time-consuming parts is responding to issues. A lot of OSS maintainers will bend over backwards to try and understand your specific problem and diagnose it, to the point of setting up new test projects, fussing around with different Node versions, reading the documentation for build tools that we don't use, debugging problems in third party dependencies that appear to be involved in the problem... and so on. I've personally spent hundreds of hours of my free time doing these sorts of things to try and help people out, because I want to be a responsible maintainer and I

Semantic Commit Messages

See how a minor change to your commit message style can make you a better programmer.

Format: <type>(<scope>): <subject>

<scope> is optional

Example

import React, { Component } from 'react';

export default function withPropsChecker(WrappedComponent) {
  return class PropsChecker extends Component {
    componentWillReceiveProps(nextProps) {
      Object.keys(nextProps)

          return nextProps[key] !== this.props[key];

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:

eddiemoore

type Undefined<T> = { [P in keyof T]: P extends undefined ? T[P] : never }

type FilterFlags<Base, Condition> = {
  [Key in keyof Base]:
  Base[Key] extends Condition ? Key : never
};

type AllowedNames<Base, Condition> =
  FilterFlags<Base, Condition>[keyof Base];
