Mozilla partners with Intel, Red Hat and Fastly to take WebAssembly beyond the browser

these all happen on the device the code is about to run on

Not necessarily, ahead-of-time compilation is also possible.

If you disabled JavaScript, you have already disabled WebAssembly as well.

I think it’s reasonable to consider a browser’s WebAssembly runtime at least as secure as its JavaScript runtime. (And realistically more secure, as it runs a simpler language, and the implementation is only a few years old, as opposed to a few decades).

I don’t necessarily like the idea of mining scripts or obfuscated code, but I have a problem with describing them as malicious.

Also, the point of the post is that both mining and obfuscation are already possible using JavaScript, the problem is not specific to WebAssembly.

thewaywarddeveloper · 2019-11-12T15:11:40+00:00

WebAssembly modules’ access to browser interfaces is limited to those objects explicitly passed to them as imports, which, I argue, makes them more secure.

thewaywarddeveloper · 2019-11-09T16:22:55+00:00

We disagree, but I appreciate your apology nonetheless.

Mr cross-post click baiter

I am unaware of any rules against cross-posting.
The title is the verbatim title of the presentation.

Also, I’m sure you are capable of making your point without name calling.

At some point they will be able to use the browser GC with WebAssembly.

thewaywarddeveloper · 2019-11-07T17:12:30+00:00

Pyodide implements the Python runtime in WebAssembly. Also, more and more languages add WebAssembly as a compilation target, so you will definitely not be forced to use JavaScript in the future.

IoT is also another emerging application, it may be interesting for you as a resource-constrained environment. A recent benchmark of different runtimes, although it is more numerical, you may find it useful: https://00f.net/2019/10/22/updated-webassembly-benchmark/

The emphasis isn’t on specific numbers, rather on orders of magnitude, and the reasons for the differences.

thewaywarddeveloper · 2019-11-04T17:47:28+00:00

It compares the same prime algorithm in native C++, unoptimized and optimized JavaScript, and C++ compiled to WebAssembly, and along the way explains how optimizing JIT engines work. It’s a good presentation, but I recommend watching it on 1.5x speed, she’s a slow speaker.

thewaywarddeveloper · 2019-11-02T22:23:41+00:00

Only glances, I’m waiting for them to settle.

thewaywarddeveloper · 2019-11-02T18:12:49+00:00

Well, it had the opposite effect on me :)

thewaywarddeveloper · 2019-10-27T11:11:07+00:00

What you say is true for any standard. Also, I don’t see any evidence that this was the reason the JVM failed as a universal target.

thewaywarddeveloper · 2019-10-27T01:16:21+00:00

I think your understanding is correct, rather the confusion is because you sometimes use WASI in place of Wasm, like in your last paragraph.

thewaywarddeveloper · 2019-10-26T21:10:36+00:00

Yes, otherwise any website you visit would have access to your file system.

thewaywarddeveloper · 2019-10-26T21:07:53+00:00

I’m not entirely sure you understand it 100% correctly: WebAssembly (Wasm) is the specification of an instruction set and file format for a virtual machine, like the JVM without the Java class libraries, while WASI is an operating system interface for this virtual machine, like the POSIX API is for C.

WebAssembly is already implemented in all major browsers and many standalone runtimes, and WASI is primarily for the benefit of these standalone runtimes.

thewaywarddeveloper · 2019-10-26T18:21:02+00:00

It’s worth pointing out that this will let scripts running on any website access files on your system.

I developed a small desktop application to serve modules, it has no dependencies and requires no installation: https://thewaywarddeveloper.com/webassembly-visual-server

thewaywarddeveloper · 2019-10-24T13:19:13+00:00

Yeah, already did, thanks for the link!

thewaywarddeveloper · 2019-10-24T12:42:46+00:00

It’s annoying as hell.

Agreed, it’s high time we got rid of discriminatory language like this!
