Ask HN: Good place to get help on / learn WebAssembly? (beginner level)

I started to get some interest in WebAssembly after seeing the possible applications and decided to take the leap this week-end.

I managed to get past the hello world stage on my own with some help from stackoverflow but I'm now stuck while trying to re-implement my js game of life in wasm. The IRC #webassembly does not seem active.

Any good place you know for some practical advice ?

The webassembly, emscripten, mozilla docs are a bit overwhelming and not that much example oriented and the tutorials I found are probably out of date on many aspects considering the moving target that WebAssembly is...
