Using ADB to control Accessbility settings for easier testing with Android Emulators + Real Devices

It's a lot easier to test accessibility on the fly using ADB. This gist attempts to make the days of navigating through the Android device settings UI to change Accessibility settings obsolete.

These ADB commands will hopefully encourage Android developers to test and use their apps with common Accessiblility settings enabled.

Credit to James Nitsch for inspiring this, and for figuring out the put commands to enable these settings.

Font Scale (Font Size -- Testing Dynamic Text)

These are instructions for setting up git to authenticate with GitHub when you have 2-factor authentication set up. This authentication should be inherited by any GUI client you are using. These are intentionally brief instructions, with links to more detail in the appropriate places.

Download and install the git command-line client (if required).

Open the git bash window and introduce yourself to git (if required):

git config --global user.name 'Firstname Lastname'
git config --global user.email '[email protected]'

A composable pattern for pure state machines with effects

State machines are everywhere in interactive systems, but they're rarely defined clearly and explicitly. Given some big blob of code including implicit state machines, which transitions are possible and under what conditions? What effects take place on what transitions?

There are existing design patterns for state machines, but all the patterns I've seen complect side effects with the structure of the state machine itself. Instances of these patterns are difficult to test without mocking, and they end up with more dependencies. Worse, the classic patterns compose poorly: hierarchical state machines are typically not straightforward extensions. The functional programming world has solutions, but they don't transpose neatly enough to be broadly usable in mainstream languages.

Here I present a composable pattern for pure state machiness with effects,
