Is there anywhere a "hello world" or simple DOM modification program which I can implement with WebAssembly?
But you can use the WebAssemblyExplorer https://mbebenita.github.io/WasmExplorer/: There is also a nice video about using WebAssemblyExplorer and even uses a simple WebAssembly-Module: https://www.youtube.com/watch?v=3XrGjSnPHGY&t=310s
This article in few lines lists key differences between PNaCl and WebAssembly: --- WebAssembly defines no new platform APIs other than some APIs for loading and linking WebAssembly code, relying on standards-based Web APIs for everything else. WebAssembly differs from asm.js by defining a bytecode format with some new operations JS doesn't have, so some spec work was required (and has been done!). Like asm.js, WebAss…
I don't really understand what "the compiler is trusted" means. What could an evil compiler really do? Maybe add a spinning loop to waste CPU cycles, but that can be done in JS too.
This does not change Firefox being on its final death throes though.
Chrome won where it counts.
I don't really like the headline. I don't want Mozilla to "win", and I don't think Mozilla wants to either; I want the open web to flourish. That said, the article is very informative, and well-balanced. It was really good of Google and the other browsers to join the wasm bandwagon. And yes, although as the author himself points out, "proclaiming a "winner" is unimportant or even counterproductive", Mozilla does dese…
The general message being: "Mozilla are being very diplomatic and restrained, whereas many in their current position would be outright celebratory"

Both PNaCl and WebAssembly need a compiler to a get the machine code run by CPU, but the output of PNaCl is checked via NaCl verifier while nothing checks that the output of WebAssembly is safe machine code. As the verifier for NaCl is likely to be an order magnitude smaller than a component in WebAssembly implementation that verifies and compiles the bytecode to the native code, PNaCl attack surface is much smaller.
Webassembly is an overcomplication. But, as always, I suppose we have to live with it.

Congrats for winning! This does not change Firefox being on its final death throes though. Chrome won where it counts.
Thus, Google's interests align with the users', and also Mozilla's. It's perfectly possible for this to change when, for example, it becomes lucrative for Google to move people from the open web to android apps. At that point, we should all hope to have Mozilla and others like it still around.
It shouldn't be surprising that Google can outcompete any other organisation when it sees something as relevant to the absolute core of its business.
