At the moment, wasm can only call functions that were passed as values of the import object which is passed to to one of the instantiation functions (e.g. https://developer.mozilla…

That came from one of Lin's first posts about WebAssembly: https://hacks.mozilla.org/2017/02/a-crash-course-in-just-in-...

I wouldn't say this is "tied" to ES6, but rather intends to integrate nicely. If a developer has no interest in being called by or calling JS, they should be able to ignore the ES6…

The current plan ( https://github.com/WebAssembly/design/blob/master/Web.md#imp... ) is to integrate WebAssembly into the ES6 module system (so you could have a JS module import a …

asm.js now allows the heap to be resized (by replacing the heap's ArrayBuffer with a newer, bigger ArrayBuffer that was either copied or produced via ES7-proposed ArrayBuffer.trans…

On x64 in Firefox, at least, there are no bounds checks; the index is a uint32; the entire accessible 4GB range is mapped PROT_NONE with only the accessible region mapped PROT_READ…

For (1): You're right that an option is to compile the VM itself to asm.js (since the VM is usually written C/C++ code; JITs are an obvious exception since they generate machine co…

The 'war on native' has multiple fronts and this post is just reporting on one of them. For many apps, I agree that the items you've mentioned are the most significant and progress…

I've always thought that this ranked among the most obscure: typedef int F(int); class C { F f; }; int C::f(int i) { return i; } I've never seen it used in practice...

Agreed, I was just replying to the OP that, even on desktop using scalar ops, there are advantages to single vs. double precision ops.

Referring to http://agner.org/optimize , both Nehalem (Intel Core i7) and Jaguar (AMD Kabini) instruction tables: you are right that addss, subss show the same latency as addsd and…

Hah, you beat me to it :)

You're right, if they left out the + sign on the beta keyboard UI they probably forgot all the calls to free(), WebSockets, and maybe CSS. Outlook is bleak.

Wow. 45 fps in a Firefox nightly, 20 fps in Chromium. Pretty impressive for JS.

Paging isn't cheap; neither are cache misses.

Umm, the claim wasn't speculative, it was measured on an aurora release that you can test out right now: http://www.mozilla.com/en-US/firefox/channel .

Boot To Gecko is not a project to build an operation system. IIUC, Mozilla is planning to reuse Linux and core components of Android. If anything, I would think Boot To Gecko would…

Yeah, it seems to be a Linux thing; Andreas was explaining that the font-rendering is highly platform-dependent.

If the title was "Could Go be used instead of C for a great many applications?" then the author would stand a chance at making a point. However, asking whether Go can "replace" C s…
