Never touch your local /etc/hosts file in OS X again

To setup your computer to work with *.test domains, e.g. project.test, awesome.test and so on, without having to add to your hosts file each time.

Requirements

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

HLS streaming from node

Provided that you already have a file or stream segmenter generating your .m3u8 playlist and .ts segment files (such as the ffmpeg 'hls' muxer), this little node server will serve up those files to an HLS compatible client (e.g. Safari). If you're using node for your streaming app already, this obviates the need to serve the HLS stream from a separate web server.

	There is a javascript console, called JSC, in:

	/System/Library/Frameworks/JavaScriptCore.framework/Versions/Current/Resources/jsc

	JSC is not in the shell PATH by default, to fix that:

	$ sudo ln /System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Resources/jsc /usr/local/bin

	Note that you'll have to use debug() instead of the conventional console.log() in your script to see any output.
