How different is it from the semantic Web (schema, RDF, OWL…)? Instead of reinventing something, why not using a well established technology that can also be beneficial for other usages?

In this article, I illustrate how Data-oriented Design helped to remove annoying memory pressure and lock contention in multiple sorters used in the Matrix Rust SDK. It has improved the execution by 98.7% (53ms to 676µs) and the throughput

Thanks for mentioning this other possibility! To be honest, I've discovered this possibility from you. Sadly, it doesn't improve the performance that much. We get the following performance: - time: 98ms - throughput: 101Kelem&#x2F

WebAssembly only supports i32, i64, f32, and f64 for the moment. So you need to allocate the string manually inside the Wasm memory, then pass the pointer of that string to the Wasm function. I will add an example to showcase that, many peo

At my work, we have developped `loupe`, a Rust crate that does precisely that, https://github.com/wasmerio/loupe/ . I'm the main author of it. `loupe` provides the `MemoryUsage` trait; It allows to know the si

I recommend this excellent reading, https://00f.net/2018/11/25/webassembly-doesnt-make-unsafe-la... . It clarifies what “safe” means in this context.

The best way to help right now is to test it, and report any issues! I've been able to try it on Windows so far for instance. Also the API isn't complete. We need to be able to grow the memory for instance. We need to understand t

That's true. However, it allows to integrate your Wasm program to your favorite framework more easily. It's likely to be a small surface of code to review carefully. It's always a balance :-).

We don't support that yet, but we are working on it. It's not that easy even if the theory is kind of simple to explain. The implementation in the different backends is mostly the challenge. The Python extension uses the Wasmer ru
