What the Heck is WebAssembly, and do I Have to Learn C Now?

Presented by @callahad at Twin Cities Code Camp, April 2016.

Note: As of April 2016, you must use Firefox Nightly and manually set javascript.options.wasm to true in about:config, or use Chrome Canary and enable "Experimental WebAssembly" in chrome://flags for native WebAssembly to work.
