Comparing Earthly and Toast for isolated / repeatable development.

Calculate a performance floor by running a fast command, echo, in the context of a large container (the emscripten SDK takes up about 1 GB).

After the initial build and caching, Toast takes 800ms and Earthly about 7 seconds on my 2020 M1 Macbook Air.

• MacOS 12.5
• Docker Desktop 4.10.1
• Toast 0.45.5
• Earthly v0.6.20 ad869c06c884b10f88948b5852ab22b4d7262e20

"Serverless" WebRTC demo

Start a server on localhost and open index.html (the host) and index.html#client (the client) in two different browser windows. They'll do their lil' p2p connection discovery dance via the wonderful public service that is https://patchbay.pub/ and, once established, a video-only camera feed from the client will display on the host.
