First the tor announcement and now this. That's a lot of exciting News from Mozilla recently.

  Well, this was a couple months ago. See https://news.ycombinator.com/item?id=16811721 https://news.ycombinator.com/item?id=16811721 for the past discussion. Definitely still exciting though.

Way to go Mozilla. This is awesome.
krisdol 8y ago
This looks awesome. Really useful tooling + gorgeous interface + clean fonts. Mozilla's looking pretty good lately.

Nice video but (unrelated to the IDE) in order to use a printf from js it was necessary to: provide a js emulated syscall to c file that calls another c function that calls back to js again

  Yeah, it’s super weird when most people are expecting this to compile into JavaScript running in a browser. Nevertheless, to be fair, this isn’t a C, C++, or Rust to JavaScript compiler-compiler it’s a C, C++, or Rust compiler that targets WebAssembly. I realize this might read as overly pedantic but it explains why it makes sense to the implement the C interface. It’s also a reasonable optimization pass for a mature compiler when it knows that you’re targeting WebAssembly running in a browser.

I felt like seeing a lisp machine

  yeah, web assembly vm is a stack machine
  - agumonkey 8y ago
    not only that, the fact that you have programmatic access to low level semantics up to presentation into a "single" window and language. Very dynamic and multilayered

  I've never seen a Lisp machine, but when I use Chrome's developer tools, which can display complex, interactive objects right in the text console, that's what I think about.

    Devtools reminds me of the Smalltalk environment.

      it's not far in spirit, but it's still quite far away

The WebAssembly Studio may track its usage through telemetry. We use this information to improve user experience. This information is not made publicly available.

env: { __syscall0: function __syscall0(n) { return syscall(instance, n, []); }, __syscall1: function __syscall1(n, a) { return syscall(instance, n, [a]); }, __syscall2: function __syscall2(n, a, b) { return syscall(instance, n, [a, b]); }, __syscall3: function __syscall3(n, a, b, c) { return syscall(instance, n, [a, b, c]); }, __syscall4: function __syscall4(n, a, b, c, d) { return syscall(instance, n, [a, b, c, d]); }, __syscall5: function __syscall5(n, a, b, c, d, e) { return syscall(instance, n, [a, b, c, d, e]); }, __syscall6: function __syscall6(n, a, b, c, d, e, f) { return syscall(instance, n, [a, b, c, d, e, f]); },

Fast forward few years later - web is made of executables and openness and user control is gone.

  To be honest minimised JavaScript code isn’t much more readable.
  - ethanwillis 8y ago
    This is why Stallman says we need to push to have a link out to the un-minified (or in this case source code that led to the WASM) so that people can go and read the source.
    - ben-schaaf 8y ago
      We already have this, there's nothing stopping you from using source maps in production. They're automatically loaded by browsers and can contain the full source code.

  That’s a big downside and something I don’t like. But if we get actual universal bytecode out of it, it will have been worth it. Every platform out there, with the same bytecode and with a myriad of OSS languages out there able to target everything under the sun. It would take us out of the dark ages of having everything in C cause lowest common denominator...

    1995 wants its Java 1.0 back ;)

Binary explorer in cloud IDE is beautiful ;)

Out of curiosity, does anyone know what the sample_rate query parameter in this URL is for?
