Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style

FILE SPACING:

 # double space a file
 sed G

 # double space a file which already has blank lines in it. Output file
 # should contain no more than one blank line between lines of text.
 sed '/^$/d;G'

These snippets provide a foundation for starting and stopping supervision trees at runtime using feature flags (e.g. Launch Darkly).

Some things to note when adapting these snippets:

1. application.ex needs to be adapted into an existing application. The important part is that each child spec provided is compliant, and that there is a feature flag (ld_key) specified.
2. As written, if a feature flag fails for some reason, it defaults to starting all children. There is room for adaptation here as needed.
3. This implementation will still require a FeatureFlags module to be available that implements is_on?/2. Adjust as needed to accomodate your own feature flag setup.
