hlfcoding / wikipedia-2015.user.css
Created December 6, 2015 10:12
For those who've donated the previous year(s) and don't want to be bothered on each page view with no recourse in the actual UI, which is btw a totally rude UX thing to do.
.frbanner {
display: none;
}
#mw-page-base {
margin-top: 0;

Using NationBuilder iOS SDK with Swift

Additional Steps

  1. Put use_frameworks! in your Podfile. Use pod 'NBClient', '~> 1.3.0'. Re-run Cocoapods.
  2. Add bridging header to your project. See [guide].
  3. Refer to the same AppDelegate source to continue.

StateMachine
  • StateMachine
    • #constructor
      • should allow setting initialState
      • should allow registering State's
      • should allow registering Transition's, and a fallback Transition
    • #switchState
      • should allow switch between available State's
      • should perform a transition before calling #onEnter on new state
      • should return a promise, done or fail
  • should emit an event, done or fail

hlfcoding / Learn CSS the Hard Way.md
Last active March 16, 2023 19:16
Learn CSS the Hard Way - Example-driven talk that focuses in-depth on CSS2 fundamentals and best practices for real-world scenarios. Examples are interactive. There are also resources (below) for further learning. Everything is online for future reference and experimentation: http://codepen.io/collection/XOLJBj

Introduction (5min)

  • (Setup: http://codepen.io/hlfcoding/pen/vEzpVd, stopwatch, printout of this, all pens loaded.)
  • Reason for this talk: better 'general knowledge of' (will be less lost) / 'fundamental knowledge how to' (will do it right).
  • Format of the talk. Provide general outline. Q&A time after each point.
  • History and personal history with CSS.
    • How complexity has been introduced in places and resolved in others.
